The Imagestore 750 is a master control and branding processor for highly automated specialty channels, capable of inserting up to four layers of graphics into HD or SD. The graphics layers can be fed by an external graphics device such as an Intuition XG or from internally stored stills and animations. The Imagestore 750 also offers character generation and clock insertion. It is ideal for downstream banding or master control switching applications.

Its integrated audio engine provides multi-channel mixing and voice-overs. Audio is accepted either as embedded SDI or from 16 AES input connectors. The Imagestore 750 provides 16channel audio mixing and playout with dynamic shuffling and gain control. Background audio is automatically “ducked” during voice-overs. It supports multi-channel audio clip storage and playback of up to 16 channels in four audio streams. Playback of stored audio clips is called Easy- play 2. Advanced audio options include audio description (AD), stereo-to-5.1 up-mixing, and Dolby processing with up to 4 Dolby decoders or encoders and sophisticated metadata processing.

An extensive range of options and upgrades are available for the Imagestore 750, including video A/B mixing, audio mixing, Emergency Alert System (EAS) and a temperature probe. Its high-performance graphics capability includes dual-window 2D DVEs on both program and preview outputs. See figures 2-1 and 2-2.

A template-based character generator (called Easytext) can insert crawl layers or static text layers that are dynamically updated. High quality characters are output with 256 level antialiasing, with easy control over drop shadows and transparency. Unicode characters in TrueType fonts are available from 6 to 600 pixels, in any RGB color.

The Imagestore 750 has a master control option. This option turns the Imagestore 750 into a powerful master control switching and branding channel designed for automated, multichannel environments. The option provides multi-channel arbitration for multiple panels, channel branding (through Intuition XG or internal stores), video and audio switching and a robust and scalable control system. The master control option is typically used in conjunction with other associated devices such as automation, the NV9000 Router Control System, Intuition XG, iMC control panels and monitor walls such as Kaleido-X. Automation drives upstream content from video servers and causes the channel to synchronize router switches with appropriate video/audio mixing, graphics keying events, DVE moves, audio switches, and so on. The

Introduction

Functional Features

Imagestore 750 transition engine synchronizes the overall transition by driving the NV9000 Router Control System to make router switches at appropriate times, driving the Intuition XG graphics output, and performing its own internal transitions as required. Panel operators may use any iMC control panel to acquire ownership of the channel manually to preview channel states, override automation, and adjust a number of other channel settings related to transitions, media loading or system configuration.

The Imagestore 750 can be used with the Xmedia Suite’s work order management, graphics preparation, asset management, data interfacing and playout automation workflow tools. The Xmedia Suite streamlines graphics operations in localized and distributed environments, and contributes to lower costs, faster delivery, and greater creativity.

The Imagestore 750 provides SNMP support for system monitoring and diagnostics, and provides configurable alarms and traps.

Introduction

Architectural Summary

The Imagestore 750 has 8 video inputs, HD or SD. Each SDI video input feeds the internal video buses (program, preview, monitor, and clean-feed) and one parallel audio-processing block. The Imagestore 750 has line FIFOs for all 8 SDI inputs for timing adjustment. Embedded audio can be de-embedded from any 4 of the 8 inputs, and then be manipulated as required by the Imagestore 750’s audio engine.

The program video bus (PGM) has an A/B mixer, four keying layers and an optional dual-window 2D DVE. The A/B mixer allows the PGM output to be transitioned between two SDI video streams. Each of the keying layers may be fed graphics content from its own dedicated store or any of the three available external fill and key pairs, and then keyed over the background video. The stores can be loaded with a still image, animation, Easytext template, analog/digital clock, or Emergency Alert System (EAS) crawl. All available media files are stored in the media library (compact flash or hard disk, depending upon the option purchased) and then loaded into the internal stores on demand. The dual-window 2D DVE is used to create picture-in-picture squeeze effects which can be dynamically positioned between different keying layers on the program video bus.

The preview video bus (PVW) has four keying layers and an optional dual-window 2D DVE. Each keying layer shares graphics content with the corresponding program keying layer, but can be controlled independently in order to preview graphics before they are viewed on-air. Similarly the dual-window 2D DVE can be used to preview DVE moves before they are played on-air.

The clean-feed (CLN) and monitor (MON) video outputs allow a number of different internal points within the video system to be sampled and viewed for partial branding or monitoring purposes. For example, the CLN output can take its output from DSK3 of the program bus to show a partially branded version of the program output, without a station logo.

A fail-safe mechanical video relay bypass connects the A video source to the program output directly and connects the C video input to the preview output (PVW) directly when a power supply problem occurs. The bypass mechanism is shown in Figure 2-1.

The Imagestore 750’s audio engine accepts audio inputs from four embedded SDI feeds, 16 AES pairs, and from the multi-channel Easyplay2 audio clip player, which gives simultaneous playout of up to four audio clips sharing a total of 16 channels. The audio engine provides 16-channel A/ B mixing and multiple voice-overs. During voice-overs, background audio is automatically ducked. Silence detection automates control of multiple independent voice-overs fed from the same Easyplay clip. (Silence detection is typically used in a multi-language broadcast environment.)

Optional audio modules can be added that provide integrated support for Dolby encoding and decoding, and stereo-to-5.1 up-mixing. The audio engine complements Dolby and up-mixing with advanced metadata processing. Audio description (AD) allows a background commentary track to be mixed with the background audio for people who are visually impaired.

One of up to 16 possible tap points from the audio engine can then be dynamically assigned to each of the available unit outputs, to the four embedded outputs (PGM, PVW, CLN, MON), to the external AES outputs, and to the level metering.

 The audio engine is configured using the ‘Audio Graph’ page of the Imagestore 750

An Ethernet interface provides rapid transfer of images and animations using Media Conversion Software (MCS) and other third-party media management applications. This interface also allows the transfer of images between a PC and the Imagestore 750 using Miranda’s Vertigo Xplorer.

Joystick

User Manual

The Front Panel

The front panel has a 16×2 alphanumeric display which is used for status and for configuration. It is used in connection with a 4-position joystick:

Fig. 2-7: Imagestore 750 front panel display and joystick

Using the joystick, an operator can navigate efficiently through a fairly large menu system. The menu system is hierarchical. See Appendix A for a complete description of the menu.

Moving the joystick down has two functions, depending on the current position in the menu system.

• It accesses the first item in the list of items belonging to the menu currently displayed.

• If the current menu item has no list of items (i.e., it is a leaf node in the menu tree), the item is

an operand and moving the joystick down selects the value of the operand as the current value of the parameter it represents.

Moving the joystick up causes the display to go up one level in the menu tree. At the top level, moving the joystick up has no effect.

Moving the joystick left or right selects the previous, or next, item in the list of items at the current menu level.

Symbols and Conventions

Where this user manual discusses joystick input, it represents the 4 positions of the joystick with the terms ‘[esc]’, ‘[enter]’ or the arrow icons

At times, additional symbols are shown on the top line of the display, at the right hand edge. These highlight the state of either the A/B Mixer (video or audio) or the keyers. These symbols represent:

In this scenario, an Imagestore 750 provides a combination of logo insertion, animations, basic text crawls and picture-in-picture DVE squeeze effects. Moreover, advanced graphics can be achieved using an Intuition XG, advanced audio processing (Dolby decode/encode, up-mix, AD). Voice-over mixing can also be applied to the background signal. In this scenario, everything is under control of automation, but an RCP-BR control panel can also be used for branding control.

Three Scenarios

Master Control Switching

The Imagestore 750 can be used as a traditional master control switcher. Automation controls arm-and-take transitions involving router sources for A/B mixing, keyer control, DVE squeezes, voice-overs and Intuition XG graphics. iMC panel operators can take manual control of the channel processor whenever it is required to override automation. Output from the channel processor is fed back to the station router for distribution to the outside world; media servers, local monitor walls, and so on. Sources are grouped to make it easier to manage multiple sources.

The Imagestore 750 is the hub of this control system, managing routing through an NV9000 router control system and using the advanced graphics of an Intuition XG. If the Imagestore 750 ever fails, it can be quickly bypassed using a redundant backup channel.

Branding Insertion Options for Intuition XG

Advanced branding from the Intuition XG (including audio embedded in the fill signal) can be inserted into the program output in several different ways.

Fill/Key Branding Insertion

This example feeds the video source into the Imagestore 750, which performs A/B mixing, DVE squeezes and basic branding. The Intuition XG’s fill and key outputs also feed rich multi-layered graphics into one of the Imagestore 750 keying layers, contributing to the final program output. All audio mixing and processing is performed by the Imagestore 750, although the Intuition XG can supply voice-overs in its fill signal.

Fig. 3-3: Fill/Key Branding Insertion

A benefit of fill/key branding insertion is that the graphics device is not in the direct signal path and will not affect output in the event of a failure. Also both devices can be controlled as a single “channel processor” by automation and iMC control panels. The main disadvantage is that it is difficult to synchronize Intuition XG graphics with DVE squeezes.

Downstream Branding Insertion

This example feeds the video source to the Imagestore 750, which performs A/B mixing of video and audio plus performs advanced audio processing such as Dolby decoding or up-mix. Output from the Imagestore 750 is then passed downstream into the Intuition XG which performs DVE squeezes and applies rich multi-layered graphics to give the final program output. The Intuition XG can also play out and mix audio clips with the program output as embedded audio.

Applications

Three Scenarios

Fig. 3-4: Downstream Branding Insertion

A benefit of downstream branding insertion is that the DVE and branding are performed by the same device, which is much simpler to configure and automate. Also AFD data can be used for graphics positioning. Dolby E and Dolby Digital (AC-3) can be passed through the Intuition XG, but cannot be manipulated. The main disadvantage is that the graphics device is in the direct signal path. In addition, this scenario is not supported by the master control option.

In-Stream Branding Insertion

This example feeds the video source to the Imagestore 750, which starts by performing A/B mixing of video and of audio. Output from the A/B mixer is then routed into the Intuition XG, which performs DVE squeezes and applies rich multi-layered graphics to the video signal. The fill output of the Intuition XG then feeds one of the Imagestore 750’s keying layers to provide the final program video output. Advanced audio mixing and processing (Dolby decode/encode, upmix, AD) is performed by the Imagestore 750 in parallel with video through the Intuition XG. The Intuition XG can play out and mix audio clips with its output as embedded audio to be used by the Imagestore 750 as a voice-over. Although simple processing of PCM background audio could be performed by the Intuition XG, there are better monitoring possibilities if it is always done by the Imagestore 750. Further, there will be no inconsistencies in audio output if the Intuition XG is ever removed from the signal path.

User Manual

This scenario combines the advantages of both “fill/key branding insertion” and “downstream branding insertion.” The Imagestore 750 acts as a robust bypass for the Intuition XG. If the Intuition XG ever fails, the Imagestore 750 keyer receiving Intuition XG graphics is cut down and an unbranded (or lightly-branded) version of the original video source will continue to be output without any break in signal integrity.

Agile Audio Handling

Video sources feeding the Imagestore 750 can have different input audio configurations, some including Dolby data and others, PCM audio. To maintain a constant output audio mapping as the A and B inputs switch between different router sources (or sources change audio format dynamically), the Imagestore 750 mixes between different audio configurations by selectively using Dolby decode, up-mix and Dolby encode audio modules.

Example 1

In this example, sources that feed the Imagestore 750 inputs will always be in one of two possible audio formats: 5.1 PCM + 2.0 PCM and 5.1 Dolby E + 2.0 PCM.

The two input audio streams are passed into Dolby E decoders which dynamically convert audio to a format suitable for A/B mixing (5.1 PCM + 2.0 PCM). The audio A/B mixer then transitions (fades or cuts) between sources, a voice-over can be mixed, and the output is encoded back into the required Dolby E configuration (5.1 Dolby E + 2.0 PCM).

Propagation Delay

With the DVE in circuit, the delay through the Imagestore 750 is 2 interlaced fields or 2 progressive frames depending on the video standard. See DVE (for Program and Preview) on page 41 for more information.

Without the DVE in circuit, the delay through the Imagestore 750 can be up to 1 line. The delay consists of input line’s FIFO depth delay (which depends on the adjustment of the reference timing) plus a minimum video processing propagation delay.

The video propagation delay for the Imagestore 750 is as follows:

Video Standard Propagation Delay

525i / 59.94

625i / 50 Hz 5.4 ms

1920 × 1080i / 59.94 Hz 2.6 ms

1920 × 1080i / 50

1280 × 720p / 59.94 Hz 2.6 ms

1280 × 720p / 50 Hz 2.6 ms

Table 4-1: Video Standard Propagation Delay

Hz 5.4 ms

Hz 2.6 ms

Reference

Embedded audio delays are different from those of video. Embedding and de-embedding circuits are required by SMPTE standards to buffer many samples before processing. The Imagestore 750’s audio “through-path” propagation delay is measured in audio samples (~20 per audio sample at 48

kHz). Because audio sample duration is significant compared to video

line duration, embedded audio samples present on input video line L will be processed, then output, on video line L + N, where N is variable and depends on both the video standard and line L. As a rough guide, N is generally 5 to 12 lines.

Reference Types

The Imagestore 750 locks to one of the following inputs, in order of priority:

REF IN Analog reference input, if present and compatible PGM IN If present and at the correct video standard

Otherwise the Imagestore 750 will free-run.

Adjusting Reference Timing

 Always adjust reference timing off-air because it can result in a loss of picture in downstream

equipment. Errors can occur in the SDI stream as the adjustment is taking place.

The Imagestore 750 has one FIFO on each input for simplified system timing. You can modify the reference offset using the front panel menu. Select Setup > Reference > Offset.

Then choose either:

Lines/Samples Lines/uS

Use the front panel arrows to increase or decrease the offset value. For any video standard, the factory default reference timing is 0 lines plus half the length of a video line. This setting buffers about half a video line for inputs that are timed to a reference offset of + 0 lines + 0 samples (or + 0 lines + 0

ms).

Reference adjustment affects the line number marking of the output stream. The reference must be adjusted to match the input signal timing of the local facility. Ancillary data such as timecode, captions and audio metadata may be missed by downstream equipment if they are not present on the same line on which they were input. If the output reference timing is not set correctly, problems might be seen such as:

• Loss of timecode.

• Loss of closed captions.

• Errors in embedded audio.

• Errors in Dolby E streams.

Note that reference adjustment affects the line number marking of the output stream. The reference must be adjusted to match the input signal timing of the local facility.

An SDI data analyzer is needed to monitor the timing of the SDI input sources and the outputs with respect to the facility reference.

Features

Reference

Clean switching between the inputs is made possible by buffering the input FIFOs to co-time them before processing. The reference timing adjusts the active depth of the FIFOs to accommodate small timing differences between the input signals.

The shortest video processing delay from any input through the Imagestore 750 to the program output occurs when the input FIFO depth is at its minimum. By increasing the output reference timing with respect to PGM IN, the FIFO depth is lengthened, up to its maximum of 1 line.

 To be valid, the input timing value must be negative. If the value is not negative, the refer-

ence offset must be adjusted so that the input timing value is negative.

HD Example (1080i)

Timing is dependent on the relative phase between the SDI input and the reference. The following example illustrates how to set up HD signals with a tri-level sync to achieve the minimum delay through the unit:

• Assume that the HD input arrives 3 μs later than the associated tri-level sync (+0 line +3 ms).

• Assume that the minimum processing delay is about 2.6 ms for HD.

Example: Because PGM IN is 3 later than PGM IN, the minimum starting point at which to set the reference timing is (0 line +3

ms) + 2.6 ms= 0 line + 5.6ms.

The reference timing must now be increased so that some data is buffered in the line FIFOs. In this example, the line FIFO is almost empty. This is a very undesirable timing point because the FIFO is on the threshold of going from empty to full if the input timing changes slightly, resulting in a 1-line vertical shift. Furthermore, the whole video picture may show corruption precisely at the FIFO empty point.

Adding half a video line to the above reference timing provides enough buffering to accommodate the largest timing differences when the input is switched to a source that is not correctly co-timed. Co-timed inputs will then have approximately half a line buffered in their FIFOs. Any sources that arrive earlier or later will increase or reduce the FIFO depth respectively.

The following table shows line lengths of the SDI standards:

ms later than the tri-level sync and PGM OUT is at least 2.6 ms

ence by several lines then adjust the reference by the same number of lines to align the output to the unusual input timing. Then add 10 to 20 microseconds to give some buffering in the line FIFOs.

Audio Processing

Audio processing requires the IS-750-Audio6 or IS-750-Audio16 audio option to be enabled. The audio engine has the following characteristics:

• Input selection from embedded SDI (4 feeds having 16 channels) or external AES (32 chan-

nels).

Embedded SDI Audio

Embedded audio processing requires the IS-750-Audio6 or IS-750-Audio16 audio option to be enabled.

Audio can be de-embedded from 4 of the 8 available SDI inputs and re-embedded in the 4 SDI outputs. The IS-750-Audio6 option provides 4 channels of de-embedding for each feed, and the IS-750-Audio16 option provides 16 channels of de-embedding for each feed.

External AES Audio

There are 16 AES pairs (32 discrete channels) available for both audio input and audio output. The AES inputs and outputs are presented on a 68-pin SCSI D-connector to enable wiring of mating connectors to a 1RU breakout box. (The order codes for those products are ABT-32-32D110 and ABT-32-32-D75.) All AES inputs and outputs are sampled at 48 video.

kHz and locked to

Audio A/B Mixing

Audio A/B mixing requires that the video A/B mixing option be enabled. It is not available for the IS-750-LOGO.

The Imagestore 750 allows A/B mixing of multi-channel audio sources for cuts and variable rate fades with mixes being up to 48 channels wide. Audio can be configured to follow the video A/B mixer position automatically, or it can be controlled independently for lead/lag or breakaways. Depending on the type of video A/B mix, audio mixes pass through either silence (V-fades) or a 50% mix of the A and B sources (X-fades).

Voice-Overs

Voice-overs adjust the combined levels of the background audio and incoming voice-over so the audio level does not exceed the original background volume. The diagram shows how the ‘duck’ and voice-over presets adjust the actual audio levels.

Fig. 4-3: Audio level during Voice-Over - duck and voice-over preset

The duck value is the amount by which the background audio level is attenuated when the voice-over is fully on. The voice-over preset value is the level of the voice-over audio when the voice-over is fully on. Both values are given in decibels.

The Imagestore 750 Configurator’s ‘Audio Graph’ page allows you to define 8 independent voice-overs for use on the program bus. There are also 8 preview voice-overs for the preview bus which can be set to cut up or down automatically based on the arm state of the corresponding program voice-over. (See Audio Mix Blocks on page 165 for more information.)

Easyplay

 Easyplay2 requires the IS-750-EP16 option to be enabled.  Note: In software versions 3.1 and later, 16 channels of audio clip playout are also enabled by

IS-750-EP2 and IS-750-EP8 options. The Easyplay feature allows digital audio clip storage and playout of up to four independent

streams sharing a total of sixteen audio channels. Many variations are possible, such as:

Easyplay audio clips are often associated with one of the 16 available voice-overs on PGM and PVW. The associated voice-over may be configured to fade up automatically when the Easyplay stream starts playing, and fade down automatically when the Easyplay stream stops. Alternatively, the Easyplay stream can be configured to start or stop playing when its associated voiceover is faded up or down.

You can place Easyplay in a mode in which it follows video layers cuts, fades, loads and unloads automatically. In this mode, audio clips are loaded by association with image file names, and the audio clips play out (or stop) automatically when the keyer associated to the media file is cut up (or down). The association may be made with either program or preview keyers.

The Imagestore 750 supports the following Easyplay audio clip file formats:

.wav Multi-channel WAV files. (This is the preferred format.) .oxw 2-channel clips created with Audio Builder (available on the MCS CD). .oxe Multi-channel Imagestore 750 audio file created with Audio Builder.

Switching Dolby E Signals

When it is operating in a progressive video standard (720p at 50 or 59.94 Hz) and switching Dolby E signals, the Imagestore 750 must be given an interlaced reference input tri-level or SD bi-level analog reference ence. That is because Dolby E data are locked to the interlaced frame.

— and the Dolby E data must be aligned to this refer-

— such as 1080i

• 720p at 59.94 Hz = 59.94 Hz frame rate

• 1080i at 59.94 Hz = 29.97 Hz frame rate

This requirement applies to all Imagestore 750s that receive Dolby audio data, regardless of whether any Dolby decode/encode options are enabled. Imagestore 750s without enabled Dolby options can cut-switch between Dolby data streams, with the transition occurring at the mid-point of an A/B mix.

Video A/B Mixing

The Imagestore 750’s video A/B mixer is fed by any of its input sources or by an external router. The mixer’s output provides the background video source for the PGM keyers. The mixer can be dynamically configured either to cut or to fade the video. The Imagestore 750 supports crossfades, cut-fades, fade-cuts, V-fades and U-fades over variable durations, with V-fades transitioning through a predefined color field. You can define the profile of each fade type.

You can configure the audio mix to follow the video mix automatically. Choose Setup > Audio Setup > Follow Video > A/B Mix at the Imagestore 750’s front panel. Alternatively, you can configure the audio mix to be completely independent of the video.

Features

Store Memory

The entry-level Imagestore 750 (either an IS-750 or an IS-750-LOGO) provides storage shared between the 4 keying layers for up to 512 MB of images or animations with their associated keys. The IS-750-MEM-2GB upgrade expands this storage to 2

The percentage of total store memory allocated to each of the four stores can be configured. This is useful if you want to assign one keying layer to long animations, and other layers for smaller logos or external fill/key. There are two ways to change the allocation:

• At the front panel: use ‘Setup > Stores > Stores Memory’.

• In the Imagestore 750 Configurator: choose the ‘Store Manager’ tab under ‘Configuration

Mode’. See Store Manager on page 161.

You should always load media files into the store memory before they are keyed over background video. Stored images and animations can be taken to air by fade or cut transitions. An automation pre-load capability (command R7) allows the next animation to be loaded in advance while another animation is on-air, provided there is sufficient memory, to avoid playout delays on-air. However, it is preferable to use two keying layers to switch between different media whenever possible.

It is recommended that a media management system is used to transfer media to the Imagestore 750. It is possible to load media using Miranda’s Media Conversion Software (or other Miranda tools), from a USB device or via an FTP transfer (see the FTP Interface section for more information).

Keying Graphics

Keying is the process of inserting one video signal (a fill signal) into another video signal (the background signal) according to a third signal (the key signal). The key signal governs the trans-

parency of the fill signal. Fill and key signals can be obtained from the following sources:

• An external graphics playout device, such as the Intuition XG, fed into a fill and key input.

• Internal media files loaded into store memory.

You can control the following keying parameters:

• Source

• Clip, gain and transparency

• Type

• Sense

• Masking

External Graphics

You can connect an external graphics device or CG to the Imagestore 750’s BNC pairs (Fill-1, Key-1), (Fill-2, Key-2) or (Fill-3, Key-3). The fill and key signals may then be fed to any of the supported keying layers and keyed up, or down, as required.

See Keying Parameters on page 39 for a description of the various keying parameters.

Imagestore 750

User Manual

Internal Media

The following internal image file types can be cut or faded onto any keying layer with an associated store:

Images .oxt Animations .oxa Easytext .oxa Bugclock .oxa

See Keying Parameters on page 39 for a description of the various keying parameters. The images may be any size up to full-screen. Stored images and their associated keys are processed at 10-bit resolution (unless the image is stored without a key to save space in which case it is stored at 8-bit resolution).

Images

Logos and full-frame still images are defined within .oxt image files. The image file embeds information such as the on-screen position, keying source and keying type. The image’s transparency can be defined in a key image, so effects such as soft edges can be applied.

(See Keying Parameters on page 39 for more information.) You can ge n erate .oxt image files using one of the following applications:

• Xplorer

• Animation Builder (available on the MCS CD).

Animations

Cell animations are defined in .oxa animation files. The animation file embeds information such as the on-screen position (for each field or frame of the animation if necessary), keying source and keying type. The transparency of each frame may be defined in a sequence of key images, so effects such as soft edges and dynamic fades can be applied. You can define any of the following loop modes:

• Single shot

• Cycle

• In-loop-out

• Linear control

• Ping-pong

• Multiple loop

(See Keying Parameters on page 39 for more information.) The maximum length of a cell animation is limited by the available store memory, as determined

by the installed memory and the amount of memory allocated to the associated keyer, in combination with the screen area of the animation. The duration of larger animations, up to full screen, is reduced proportionally to the area used. Because areas are evaluated at each frame, animations can change in size with no penalty.

 If the last animation frame is completely transparent, then the keyer stays cut up after the

last animation frame. If the last animation frame is small (2×2) then the keyer cuts down after the last animation frame.

With 128 MB of playout memory per store, a logo that is 1/64 of the screen size can be animated for just over half a minute. Larger screen sizes or smaller playout memory sizes affect the maximum animation duration pro rata. This table shows the duration for animations at 1080i. The frame rate is 29.97 frames per second and the size of a frame is 7.91

Component images can also be imported into the animation builder from 32-bit Targa image files, allowing components to originate from almost any computer graphics system.

Easytext

 Easytext requires the IS-750-ET option.

CG text effects, including static text and simple crawls, are defined in .oxa Easytext files, or templates. The templates can comprise many text and image elements, all of which can be updated dynamically through automation. Data sources can also be defined within text elements to help achieve dynamic data-driven updates including timers, date, stopwatch, countdown, and custom data.

You can ge n erate .oxa Easytext files using one of the following applications:

• XStudioLT.

• TextBuilder2 (available on the MCS CD).

Bugclocks

 “Bugclocks” require the IS-750-Clock option.

Analog or digital clocks are defined within .oxa Bugclock files. The Bugclock file defines the properties of the clock, such as hand and face styles, and whether it shows hours, minutes, and seconds. Digital clocks can be 12 or 24 hour style. A bugclock can be locked to a station’s LTC or VITC timecode. Clocks are loaded, previewed, positioned, keyed and controlled through GPIs and automation, as are animations and static logos.

‘Emergency to Air’ and ‘Emergency from Air’

If a background video failure occurs, an emergency image message can be brought to air using the ‘Emergency to Air’ feature. The message can be triggered by automation, a GPI event, from a control panel, or from the Imagestore 750’s front panel.

When ‘Emergency To Air’ is selected, the most downstream keyer that is associated with a store (on the program output channel) fades down over 25 fields. Image V000.oxt is then loaded and faded up over a further 25 fields.

When ‘Emergency from Air’ is selected, the most downstream keyer that is associated with a store (on the program output channel) fades down over 25 fields and the previous image is restored, but not faded up.

 Note: The emergency image must be stored in the image library under filename V000.oxt.

Emergency Alert System (EAS)

 The Emergency Alert System feature requires the IS-750-EAS option.

The Emergency Alert System (EAS) is a national warning system in the United States that notifies the general public of pending or imminent situations such as weather emergencies. It can also be used by the President of the United States to deliver a message. All television stations in the USA are required to transmit EAS messages. Cable head-ends are also required to transmit EAS messages on all programmed channels. For more information on EAS, see the FCC website or the websites of the EAS receiver manufacturers.

A televised EAS alert consists of two components:

• An on-screen crawl displaying the nature of the emergency and the regions affected in the

broadcast area.

• An audio message up to two minutes in length.

The EAS option provides a mechanism for the Imagestore 750 to receive information from an external EAS receiver and then generate the required video crawl and audio voice-over. The Imagestore 750 provides flexible branding capabilities for the video crawl, using an Easytext template, such as adjustable font type, size, and color, additional images or text, etc. It provides full GPI macro programmability and enforces keyer control so that the crawl is shown for the duration of the alert.

 Note: For EAS messages (a.k.a straps) to appear correctly on DSK 4, the fourth store must be

allocated sufficient memory. See Setup > Stores > Stores Memory on the Imagestore 750’s front panel.

EAS Receivers and Interfacing

The Imagestore 750 supports the following EAS receivers:

• Sage ENDEC Model 1822.

• TFT EAS 911.

Select the EAS receiver model and Baud rate in the Imagestore 750 Configurator or at the Imagestore 750’s front panel. Choose Setup > Serial Comms > Serial Ports > Com

Keying Graphics

The following external interfaces to the Imagestore 750 are required:

• Serial input

The EAS receiver connects to the Imagestore 750 over an RS-232 serial connection. This connection provides the EAS alert data including the alert level and crawl text data.

EAS messages can be up to 1990 characters long.

• GPI input

A GPI trigger on the Imagestore 750 is used to initiate, and then terminate, the EAS alert. This GPI can come directly from the EAS receiver, from automation, or from a manually initiated trigger.

The GPI trigger drives separate ‘EAS On’ and ‘EAS Off’ macros that allow you to build a custom branding event around the EAS crawl. The macro usually includes triggering of an AES voice-over (which will duck the background audio) but can play a pre-recorded Easyplay audio clip instead.

• Voice-over input

Audio voice-over input is fed into an external AES pair on the Imagestore 750. The EAS audio message is up to two minutes duration and stored in the receiver until the alert is triggered.

Because most receivers have analog audio outputs, the audio must first be converted to AES using an external converter (such as the Miranda ADC-1711 or ASD-771p). The AES audio is then fed to the Imagestore 750 through an external AES input pair and the audio is mixed with the background through a voice-over:

Fig. 4-4: EAS Receiver interfacing

EAS Crawl Templates

The Imagestore 750 monitors its COM ports for a serial string from an EAS receiver. When a message is received, its priority (high, medium, low, or none) is established and the text is updated in one of the following default Easytext crawl templates.

For each video standard, there is a standard set of files that correspond to the appropriate EAS alert level with the appropriate background color.

Each default EAS template file can be copied (from /etc/eas/ into /home/images/) and then modified to suit your requirements in the TextBuilder application (available on the Media Conversion Suite CD). You can customize background color, crawl speed, font, size, shadow, and positioning. You can also add additional elements to the crawl such as another text field or a logo or graphical element.

Note the following considerations relating to EAS template files:

• The EAS template filename should not be changed. Otherwise, the EAS option will not be

able to find the template.

• Always use Text Builder to transfer modified files to the Imagestore 750 so that all fonts asso-

ciated with the template are also transferred.

• The datasource name “EAS_TEXT” is associated with the text crawl element in an EAS tem-

plate. Ensure that its datasource value is not inadvertently adjusted by automation because doing so can affect the EAS message on-air.

• If no text has been received from the EAS receiver, blank text will be seen in the EAS tem-

plate. Either leave this blank, or pre-set the data-source to something harmless such as “Stand by for an important EAS alert.”

EAS Triggering

 Note: EAS messages are displayed on-air following appropriate GPI triggers or automation

commands. Refer to General Purpose Interface (GPI) on page 47 for information about setting up the relevant GPI. For automation commands, refer to the automation publications listed under Applicable Publications and Tools on page 3.

When an EAS alert is triggered ‘on’ by GPI or by automation, the following internal events occur:

• The ‘EAS Layer’, which is the most downstream keyer, is cut down. Its prior keyer state and

the image loaded (if any) are saved for later use.

• The appropriate EAS crawl template is loaded into the ‘EAS Layer’. The selected crawl file is

determined by the alert level in the crawl data and the video standard. The crawl data must be received before the EAS alert is initiated, otherwise stale data will be displayed.

• The ‘EAS Layer’ is cut up to reveal the EAS alert (in the video foreground).

When an EAS alert is triggered ‘off’ by GPI or automation, the following internal events occur:

• The current EAS crawl will complete, after which the ‘EAS Layer’ cuts down.

• The previous image (if any) is reloaded into the ‘EAS Layer’.

• The ‘EAS Layer’ is restored to its prior state.

Features

Keying Graphics

• Any remaining events in the EAS alert ‘off’ GPI macro are processed. These macro events are

suspended until the preceding events complete.

Additional commands can be added to the GPI macros to provide other EAS actions. At a minimum, these events must include a ‘Voiceover On’ and ‘Voiceover Off’ command and appropriate delays to ensure that the data for the crawl is received. Such GPI macros are outside the scope of this manual, but can be discussed with Miranda Support.

Because the Imagestore 750 retains the last EAS text message received, the EASNone.oxa crawl will be seen only when the EAS mode is activated with no alert level. When verbose logging is enabled, all EAS transactions are recorded in the standard Imagestore 750 log files.

Temperature Probe

 The temperature probe feature requires the IS-750-TEMP option.

This option provides a low-cost temperature sensor (Sensorsoft ST6154J) for measuring the local temperature, typically from the roof of the building. The temperature can be recorded in Celsius or Fahrenheit, and can be displayed (and continually updated) on a keying layer of the Imagestore 750 using an Easytext template.

The thermometer connects by cable to an RS-232 serial port of the Imagestore 750 and can be located up to 1000 feet away without the need for a battery or external power adapter. It has an external stainless steel probe, suitable for outdoor applications or where liquids are present.

More information is found on the temperature probe option’s instruction sheet. That is Miranda document M987-9805-101.

Keying Parameters

You can configure the following keying parameters for both internal and external graphics.

• Source

The key source (actually the keying method) may be chosen from the following:

Separate Key The key values are derived from the luminance content (Y value) of the

separate key.

Self Key The key values are derived from the luminance content (Y value) of the fill

signal itself.

None The key for an image is set to white so that there is no image transparency.

• Clip, gain and transparency

After the key source is selected, the key signal is processed with clip, gain, and transparency to alter the mapping from key input luminance to key output values. Transparency modifies the maximum key value as follows:

Fig. 4-5: Keying Parameters - Clip, Gain, Transparency

• Type

After the key output is generated, the type controls the combining of the background and fill video signals. The Imagestore 750 supports both linear and full keying types.

Features

Keying Graphics

Linear keying is where the fill signal has been pre-computed to match the key signal. In this case, the fill has already been cut by its own key independently of the Imagestore 750. The keyer computes (1 – key) and uses this to “cut a hole” in the background signal. The fill is then simply added to this.

Fig. 4-6: Linear Keying (pre-cut Fill)

Full keying is where the fill signal must be multiplied by the key signal prior to being added to the modified background signal. In this case, the fill has not already been cut by its key. The keyer cuts a hole in the fill with the key values and cuts a hole in the background with computed (1 – key) values. The cut fill and cut background are then added.

Full Keying

Fig. 4-7: (both Fill and Background cut by Key)

• Sense

Key inversion switches the key value with the (1 – key), thereby inverting the sense of the key signal.

The Imagestore 750 supports normal and invert sense.

• Normal

A black key level causes the fill pixel to be fully transparent. A white key level causes the fill pixel to be fully opaque. Intermediate keying levels produce a pro rata transparency effect.

• Invert

This is the reverse of the normal sense. A white key level causes the fill pixel to be fully transparent. A black key level causes the fill pixel to be fully opaque. Intermediate keying levels produce a pro rata transparency effect.

• Masking

The Imagestore 750 allows a rectangular masking area to be defined for each of the 4 keyers. This mask applies to any signals received by the keyer; whether they are external fill and key signals or the output from internal stores.

For internal images, the area range of the mask is determined by the width and height of the image in pixels, and is limited by the selected video standard. To maintain correct YUV values, the pixel count increments by 2.

For external fill and key signals, the area range of the mask is limited by the selected video standard. Here too, the pixel count increments by 2.

One situation where masking an external fill and key signal is useful is when output from an external graphics device must be split between two keying layers in different regions of screen area.

DVE (for Program and Preview)

The Imagestore 750 digital video effects (DVE) options provide visual effects giving comprehensive video image manipulation, including picture-in-picture squeeze transitions over a background. The main DVE features include:

• Single or dual 2D (rectangular) squeezes over a background.

• Independent control of DVE squeezes on the program and preview buses.

• Cropping and masking of squeezes, including soft edges and colored borders.

• Adjustable layering of dual DVEs, to bring new content to the front.

• Editor for creating and modifying DVE sequences to move between different squeeze posi-

tions.

• Up to 97 different DVE sequences stored on the Imagestore 750.

• Compensating video delays, post-A/B-mix on program and preview.

The following DVE options are available for the Imagestore 750:

IS-750-DVE Enables a single DVE window on PGM and PVW. IS-750-DVE-DUAL Enabled two DVE windows on PGM and PVW.

The DVE processors provide digital video effects on any of the input video streams or A/B mixer output. Digital video effects are suitable for picture-in-picture applications such as over the shoulder news transitions, as well as squeezes for credits, news flashes, sports results, and schedules.

You can create and manage DVE sequences using the DVE Editor (available on the Media Conversion Suite CD). Using the DVE editor software, you can upload up to 97 sequences onto the Imagestore 750 for later playback.

The DVE delay is exactly 2 interlaced fields or 2 progressive frames. For 59.94 delay is 2 DVE input stream is also delayed while the video is resized.

Note: It is important for video and audio (including metadata) to maintain a constant and unchanging delay through the Imagestore 750. To compensate for any potential DVE processing, matching delays must be applied to the background video (after the A/B mix), and to the audio/metadata paths defined within the audio engine.

You can set the DVE mode to ‘enabled’ or ‘disabled’ for the program and preview buses independently. When the DVE is enabled, DVE picture insertion takes place with the DVE window(s) being keyed at the position defined by the DVE configuration. When the DVE is disabled, DVE picture insertion is taken out of circuit to reveal the background video coming from the A/B mixer. In both cases, a DVE delay is experienced at the Imagestore 750’s output.

The DVE configuration menu option of the Imagestore 750’s front panel (Operate > DVE

Config) and the Imagestore 750 Configurator allows the position of the DVE picture insertion

within the video path to be one of the following.

This diagram illustrates the 3 DVE configuration options:

Fig. 4-8: DVE insert positions:- before keyers; after keyer 1; after Keyer 2

Each heavy (red) line represents a fill/key signal from one of the DVE scalers, which is then keyed over the background video at a position that depends on the current DVE configuration.

When DVE mode is enabled, the DVE keyer will often present full-screen video (normally routed from the A/B mixer). Any DSKs that are upstream of the DVE keyer will be lost. However, it is normal to have at least one DSK upstream of the DVE keyer so that full-screen media graphics can be used to hide the background video coming through the compensating delay. These graphics will also be revealed when the DVE squeezes back from full screen.

Note: The relative positioning of DVE1 and DVE2 scalers can also be modified using the DVE sequence editing software.

When DVE mode is disabled, the background video continues to pass through the compensating video delay. The compensating delay must be set to match the delay through the DVE scalers exactly. That way, when DVE mode is re-enabled, there will be no glitch in the video output.

Fig. 4-9: DVE video compensating delay

Video Frame Delays

It is very important for video and audio (including Dolby metadata) to maintain a constant and unchanging delay through the Imagestore 750 system to avoid lip-sync problems. To help achieve this, the Imagestore 750 provides the following video frame delays:

Name Bus Position Compensates For Delays From . . . Range

Program post-AB mix frame delay

Preview post-AB mix frame delay

Program output frame delay PGM Output Audio modules 0–16

Preview output frame delay PVW Output Audio modules 0–16

Clean feed output frame delay CLN Output Audio modules 0–16

Table 4-10: Imagestore750 Video frame delays

You can configure these delays in the Imagestore 750 Configurator using

System Settings > Video > Video Frame Delays.

The ‘post A/B-mix’ delays are primarily used to compensate for the DVE and any in-stream branding insertion. The ‘output’ delays are primarily used to compensate for the audio delay through Dolby decode and encode modules.

Table 4-11: Preview output options

The Imagestore 750’s default preview output selection is used typically for previewing A/B mixer transitions, keyer graphics transitions, DVE moves, and voice-overs prior to bringing them to air on program output. In the master control environment, you can preview exactly what will happen on the program output when the next transition is taken to air.

Active Preview AB Mixer

When ‘Active Preview AB Mixer’ is enabled, the preview background video depends on both the position of the program A/B mixer and its arm state. When there is no A/B mix armed, the preview background video follows program. If an A/B mix is then armed, the preview background video shows the transition state that will occur on program after the next “Take” transition.

You can set this option in the Imagestore 750 Configurator using Video > Preview >

Preview > Active Preview AB Mixer.

When ‘Active Preview AB Mixer’ is disabled, the preview background video is controlled independently of the program A/B mixer and its arm state. The preview A/B mixer angle is normally configured and remains in the ‘B channel’ position in the Imagestore 750 Configurator (Video > Preview > Preview > Preview AB Mixer Angle).

Active Preview Keyers

When ‘Active Preview Keyers’ is enabled, preview keyer position depends on both the position of the equivalent program keyer and its arm state. Whenever a keyer is disarmed, the position of

the equivalent preview keyer follows program. If a keyer is then armed, the preview keyer shows the transition state that will occur on program after the next “Take” transition.

Note: Keyers can be armed for cuts or fades from a Miranda iMC panel, an RCP-BR / Xpanel or through Presmaster automation. This table shows how active preview keyers are driven based on the equivalent program keyer position and arm state:

Imagestore 750

User Manual

The Imagestore 750’s monitor output is used typically for monitoring video at a number of different points within the Imagestore 750. The monitor output audio mix can also be changed dynamically using ‘Audio Output Monitor Multiplexor’. (See Audio Mix Blocks on page 165.)

General Purpose Interface (GPI)

The ports of the dedicated general-purpose interface (GPI) can be used either to trigger the execution of a series of internal pre-programmed commands (input) or to monitor the status of the Imagestore 750 (output). The Imagestore 750’s GPI has 16 input/output ports.

 GPI numbering is zero-based for pinouts, automation, and the front panel. Use GPIs

numbered 0–15.

When used as an input, a GPI input is activated as follows:

GPI On When the GPI pin is connected to 0V. GPI Off When a GPI pin is not connected. (The GPI signal pin gets pulled high.)

When used as an output, a GPI output is as follows:

GPI Active(On) The GPI output pin is internally driven to ground by a Darlington

transistor (Active low is represented by +0.7V or less.)

GPI Inactive(Off) The GPI output pin is internally pulled high. Lamps or relays attached to a GPI output port can use the GP_+5V fused supply (pin 7) but the maximum current drawn should not exceed 500mA.

Features

General Purpose Interface (GPI)

Where a GPI output is used to drive a relay coil, you should incorporate reverse voltage protection diodes in the external circuit to protect the Imagestore 750 from voltage transients.

See GPIO / LTC on page 207 for details of the GPI connector pinouts. The GPI ports can be used as inputs to execute a series of internal pre-programmed commands,

or GPI ON/OFF macros. The GPI ports can also be triggered either on or off by a pre-defined transition state defined for the Imagestore 750. See GPI Inputs and Macros on page 48 and GPI

Outputs and Events on page 50 for a description of how GPI inputs and outputs are configured.

 Because GPI ports are shared between inputs and outputs (bi-directional), it is a common

practice to reserve some GPI ports solely as inputs and others solely as outputs. However, GPI input macros can be configured to be driven from GPI output events on the same port if this is required. An example might be to cut up a voice-over automatically through a macro (input) when a DSK starts fading up (output).

GPI macros, described in the following section, are directly associated with the GPI connections and limited to a maximum of 32 macros (fewer when GPI outputs are defined).

 Note that GPI macros are difficult to compose and are limited to actions that can be selected

from the front panel’s ‘Operate’ menu. You can find a more versatile, extensible, and friendly way of creating macros in the Images-

tore 750 Configurator under ‘Macro Mode’. Up to 65,536 macros can be created, each of which can be named to help the iMC control panel meaningfully represent macros to a panel operator.

Macros consist of a list of Oxtel automation commands, with delays being inserted using the ‘Xd’ automation command. See Macros on page 50 for details. For complete details of the Oxtel automation protocol, see the automation publications listed under Applicable Publications and Tools on page 3.

GPI Inputs and Macros

Any GPI input can have two associated macros:

• One macro associated with the GPI port transitioning on.

• One macro associated with the GPI port transitioning off.

Each macro can contain up to 2048 bytes of Oxtel command data. (That is approximately 200 commands.) When the GPI is triggered, the commands within the macro are executed sequentially. Pauses may be defined within the macro if they are required. The macro associated with a GPI input can also be set to trigger a macro that was defined in the Imagestore 750 Configurator.

See Macros on page 50 for more details. To create a GPI macro from the Imagestore 750’s front panel:

• Select the appropriate GPI input event.

• Select Setup > GPI > GPI Inputs. Then choose GPI In x On or GPI In x Off.

Here “x” represents the GPI number, from 0 to 15.

• ON macros are triggered when the appropriate GPI input is triggered on.

• OFF macros are triggered when the appropriate GPI input is triggered off.

• Press the joystick down [enter] to enter the macro editor.

• If the GPI is unused, the display shows ‘> Empty <‘.

and press [enter]. 5 The front panel display returns to the macro list.

Repeat this process until the required macro is completely defined. You can add delays using the menu Miscellaneous > GPI Delay. The delays are defined in terms of fields (interlaced) or frames (progressive).

To delete a command from a GPI macro:

1 Select the appropriate GPI input event. 2 Select Setup > GPI > GPI Inputs. Then choose GPI In x On or GPI In x

Off, where “x” represents the GPI number from 0 to 15. 3 Use the joystick arrows [

] and [] to select the command to delete.

4 Press [enter] and then select Delete. 5 Press [enter] again to return to the macro command list. The command selected will have

been removed from the list.

The appropriate macro is activated either when the connection is made (GPI On), or when it is switched off (GPI Off ) relative to the ground pin on the GPI connector.

To trigger a macro associated with GPI In 1 On (for example), make an electrical connection between pins GPI 1 and GPI GND. To trigger a macro associated with GPI In 1 Off, break the electrical connection between pins GPI 1 and GPI GND.

See GPIO / LTC on page 207 for the connector pinout. The GPI input macros defined for an Imagestore 750 are stored in /home/params/gpi.xml.

The Imagestore 750 can be configured for use with Miranda’s Intuition XG (a single-channel advanced HD/SD graphics co-processor).

The Intuition XG can be regarded as a co-processor. It can generate complex output incorporating multiple objects (animations, clips, images, and text) on numerous “virtual” keying layers. These scenes can then be composited into one signal that is fed into the Imagestore 750 through the fill and key inputs and keyed as a ‘Load Live’ signal on any of the available keying layers. When this signal includes embedded audio, it can provide background audio or voiceover input to the Imagestore 750.

An Imagestore 750 with an Intuition XG co-processor is often called a “channel” or “channel processor” because it collectively manages all of the video signals, effects, graphics and audio processing that are output from the Imagestore 750.

When such a “channel” is being driven by Oxtel-protocol automation, it is generally recommended that the Imagestore 750 and Intuition XG co-processor to be controlled from independent serial automation links. However, the Imagestore 750 can also be placed in a mode where it receives all commands on a single automation link and then forwards selected layerbased commands to the Intuition XG co-processor over a serial or network link. This is described in more detail under Oxtel Command Forwarding to a Co-Processor, following.

When such a “channel” is being driven by Presmaster-protocol automation, there is only one serial link from automation to the Imagestore 750. Any automation commands intended for the Intuition XG co-processor are sent as “pass-through” commands.

Imagestore 750

User Manual

Oxtel Command Forwarding to a Co-Processor

Refer to Serial Connection to Intuition XG on page 207 for information on connecting the Imagestore 750 and Intuition XG for command forwarding over a serial connection.

The keying layer parameter in the Oxtel automation protocol is always represented by a single zero-based ASCII character in hexadecimal. The character can range from 0x0 to 0xF. The numbers for the four keying layers are reserved. The higher numbers are then used to address layers on the associated graphics co-processor according to the following table:

Layer Number Co-Processor Layer Number Co-Processor

0x0 (DSK 1) 0x8 0x4

0x1 (DSK 2) 0x9 0x5

0x2 (DSK 3) 0xA 0x6

0x3 (DSK 4) 0xB 0x7

0x4 0x0 0xC unused

0x5 0x1 0xD unused

0x6 0x2 0xE unused

0x7 0x3 0xF unused

Table 4-15: Oxtel Command Keying layer forwarding to a Co-Processor

For example, if an Imagestore 750 receives a command to load a graphic into layer 0x4, it will forward this command to the co-processor to load the graphic into the first keying layer. To do this the Imagestore 750 subtracts 4 from the layer value before relaying the command.

Commands forwarded by the Imagestore 750 can potentially address up to 12 keying layers on the co-processor. However, the usable range is 0x0 to 0xB because Intuition XG supports a maximum of 8 keying layers.

Command forwarding is supported for the following Oxtel automation commands:

Automatic Keyer Management

Automatic keyer management options can be used in conjunction with command forwarding to simplify the control of Imagestore 750 and graphics co-processor keying layers.

Whenever the Imagestore 750 receives a command from automation to cut up a layer on the coprocessor, the automatic keyer management options permit a ‘Load Live’ to occur with the associated keying layer on the Imagestore 750 being cut up automatically. Also, if automation cuts down all co-processor layers, the Imagestore 750 can cut down the associated keying layer and turn off ‘Load Live’.

Set up the automatic keyer management options in the Imagestore 750 Configurator or using the following front panel menu options:

• Setup > Slave > Keyer Assign

Assigns automatic keyer management to one keying layer of the Imagestore 750.

• Setup > Slave > Keyer Follow Up

Imagestore 750

User Manual

Defines whether the assigned keyer of the Imagestore 750 is cut up automatically when

there is some keyer activity on the co-processor layers.

• Setup > Slave > Keyer Follow Down

Defines whether the assigned keyer of the Imagestore 750 is cut down automatically when

there is no keyer activity on the co-processor layers.

• Setup > Slave > Fill&Key Input

Determines which external fill and key pair is routed to the assigned keyer for automatic

keyer management.

The status of the co-processor layers controlled by command forwarding can be monitored from the Setup > Slave > Keyer Status front panel menu.

 Note: Automatic keyer management works correctly only when used in conjunction with

command forwarding. This is because the Imagestore 750 maintains the layer status

(including keyer arm states) of the graphics co-processor based on the automation

commands it forwards to the co-processor and the tallies that it receives from the co-

processor as the status of its layers changes. The Imagestore 750 always uses tallies from the

co-processor to determine exactly when slave layers cut down because they often contain

out-transitions of indeterminate duration.

In the master control environment, we recommend that ‘Keyer Follow Up’ be disabled so that Intuition XG graphics can be previewed by iMC panel users without automatically appearing onair. Automation then must be responsible for cutting up the appropriate assigned DSK with Intuition XG layers.

Example

Following is an example of automation cutting up two layers on a graphics co-processor by using command forwarding through an Imagestore 750 with the following settings:

Default Keyer Assign DSK 1 (which is initially cut down)

Keyer Follow Up Enabled

Keyer Follow Down Enabled

Fill & Key Input Fill-1/Key-1

1 Cut up one co-processor layer ‘34 1’.

The Imagestore 750 maps the command ‘34 1’ to ‘30 1’ and forwards it to the co-processor.

The co-processor cuts up its first layer.

The Imagestore 750 performs ‘Load Live’ on DSK 1 using Fill-1/Key-1.

The Imagestore 750 cuts up its own DSK 1.

The co-processor output is now visible. 2 Cut up another co-processor layer ‘36 1’.

The Imagestore 750 maps the command ‘36 1’ to ‘32 1’ and forwards it to the co-processor.

The co-processor cuts up its third layer.

The Imagestore 750 does nothing with its own keying layers. 3 Cut down one of the co-processor layers ‘34 0’.

The Imagestore 750 maps the command ‘34 0’ to ‘30 0’ and forwards it to the co-processor.

Features

Closed Captions

The co-processor completes any out-transitions and then cuts down its first layer.

The Imagestore 750 receives a ‘30 0’ tally command from the co-processor, but does nothing

with its own keying layers because there is still one co-processor layer active. 4 Cut down the final visible layer of the co-processor ‘36 0’.

The Imagestore 750 maps the command ‘6 0’ to ‘32 0’ and forwards it to the co-processor.

The co-processor completes any out-transitions and then cuts down its third layer.

The Imagestore 750 receives a ‘32 0’ tally command from the co-processor, and then cuts

down DSK 1 because there are no co-processor layers active.

Note that ‘Default Keyer Assign’ can be cut down (or up) at any point to override the automatic keyer management.

 In the master control environment, we recommend that ‘Keyer Follow Up’ be disabled so

that Intuition XG graphics can be previewed by iMC panel users without automatically

appearing on-air. Automation then must be responsible for cutting up the assigned DSK

with Intuition XG layers.

Closed Captions

Timecode

Closed caption information is usually passed through the Imagestore 750 regardless of what the closed caption option is. The reason for the option is that when the standard is set as NTSC (525), closed caption information is found within the active picture (lines 20 and 21), and it will be destroyed when graphics are keyed over these lines.

When the closed caption option is enabled ( front panel menu), the Imagestore 750 ensures that the close caption information is preserved regardless of keyed graphics being present on lines 20 and 21. Disabling the option instructs the keyers and mixers to treat these lines as part of the active picture so that they may be mixed with the key.

For HD, closed caption information is contained in vertical ancillary data (VANC) on line 9, which is outside the active picture. Because this information is never processed by the keyers, the closed caption information is preserved, regardless of the option selected.

Please note that when an SDI picture is routed to a DVE, the closed caption information might be visible at the top of the DVE window. To avoid this problem, we recommend that all DVE sequences be cropped by 2.5% at the top to remove this undesirable effect.

The following timecode formats are supported by the Imagestore 750:

Setup > Miscellaneous > Closed Cap at the

• Linear (or longitudinal) timecode (LTC).

Received on the GPI/LTC port (or its 44-pin terminal block adaptor). (See GPIO / LTC on

page 207.)

Supports dropframe and non-dropframe.

Supports forward and backward directions.

• Vertical interval timecode (VITC).

Received from the external reference.

Supports dropframe and non-dropframe.

When it is physically connected and activated, the LTC or VITC timecode source is used to adjust the internal clock once per minute. When a timecode source is not connected, an NTP server can be used to update the system clock periodically. Alternatively, the internal clock will free run.

Timecode source, timecode status, and clock time can be viewed using the front panel menu.

Message Logging

The Imagestore 750 generates message logs to record warnings and errors during operation, and (optionally) to record commands received from automation. The message log file can help diagnose a range of different issues, from invalid parameters in automation commands to hardware faults.

The Imagestore 750 maintains two message log files:

• The file messages records log messages since the Imagestore 750 was powered on.

• The file messages.old records log messages for the previous powered session, in case the

Imagestore 750 was restarted after a failure.

Message logs can be downloaded from the Imagestore 750 web page as described in System

Information on page 179.

System Configuration

Local Logging

You can enable or disable local logging to the hard disk or solid-state data storage using Setup > Logging > Local Logging at the front panel menu. Disabling local logging writes the

message log to a (volatile) RAM disk thereby reducing wear to the internal hard disk or solidstate storage. When the Imagestore 750 is restarted or shut down safely from the front panel, the volatile message log is automatically copied into physical storage for future reference.

Note: When local logging is disabled, the message log will be lost if you restart the Imagestore 750 by pulling out the power cable.

System Configuration

 See Chapter 8 for complete details regarding the Imagestore 750 Configurator.

Different Imagestore 750 system configurations can be created for different applications. For example, the Imagestore 750 can be switched between different video standards if you create two configurations and then import the appropriate configuration file when a change is required. You can use the Imagestore 750 Configurator, or the front panel’s ‘User Presets’ menu to do this.

 Note: A device restart is required after a new configuration is imported, so updates cannot

be made while on-air.

System configurations may also be transferred between Imagestore 750’s during commissioning to ensure consistency of state between them. This is most easily achieved using the Imagestore 750 Configurator. After an import, all settings within the selected configuration file are validated against the capabilities of the new Imagestore 750 to ensure that differences in hardware or options are handled correctly.

Please refer to the following sections for more information on the main system configuration:

Configuration Mode page 156

Saving a Configuration page 175

Importing a Configuration page 175

Video Bypass

In the event of power loss to the Imagestore 750, or failure of both internal power supplies, the mechanical video relay bypass routes ‘A In’ (as a background signal) directly to the program output (PGM OUT) and routes ‘C In’ to preview output (PVW OUT).

(The relays switch to the bypass position when powered off.) This feature is an emergency failsafe and is completely non-synchronous in operation. During

boot-up, the bypass is maintained until the Imagestore 750 is fully operational. At switch-over, a glitch in the video is to be expected. (A jump in video and audio might also occur if delays are applied under normal operation.)

Miranda’s iMC master control system has many modular parts and provides many options. You can order a master control system that is optimal for your facility. It can change with your needs.

The Imagestore 750’s master control option ( control switching and branding system designed specifically for automated, multi-channel environments. The Imagestore 750 controls upstream router switching through a Miranda NV9000 router control system, and interfaces with Miranda’s iMC control panels which allow manual preview and override of channels.

At the heart of a master control system are transition processors: MCEs and Imagestore 750s. MCEs reside in NV5100MC frames; the Imagestore 750 stands by itself as a 1RU processor. The iMC system can be composed 3 ways:

1 Imagestore 750s transition processors (a.k.a. “channel branding processors”), an NV9000

router control system, and iMC control panels.

The Imagestore 750s can be used with Intuition XG graphics processors for advanced graph-

ics effects. 2 MCEs (master control engines) residing in NV5100MC frames, control panels, and optionally

an NV9000 router control system.

The MCEs can also be used with Intuition XG graphics processors for advanced graphics

effects. 3 A combination of 1 and 2.

Each channel processor provides the output for a single broadcast channel (or backup channel) by taking video (with embedded audio) signals from an upstream router, mixing signals and superimposing graphics that brand the channel.

Imagestore 750s always control the upstream router sources through an NV9000 router control system and the router(s) in turn provides the video and audio inputs to the Imagestore 750s.

IS-750-Master-Control) gives you a powerful master

Master Control

Overview

Panel users can acquire and control both Imagestore 750s or MCEs with an iMC control panel. Existing broadcast facilities equipped with MCEs can be expanded by adding Imagestore 750s to create a hybrid master control system.

The following iMC control panels support Imagestore 750s and MCEs:

• iMC-Panel-300

A large panel with a large touchscreen, function buttons, control knobs and joystick.

Its main function buttons rows have 24 buttons.

• iMC-Panel-200

A medium-size panel with a large touchscreen, function buttons, control knobs and joystick.

Its main function buttons rows have 16 buttons.

• iMC-Panel-100 (supported in later IS-750 software version)

A two-part panel with large touchscreen, function buttons, and control knobs.

One part is a slim, light-weight, 3RU rack-mountable button panel. The other part is a VGA

monitor. The VGA monitor can be a touchscreen. If it is not, it is operated with a mouse.

Its function buttons rows are 16 buttons wide.

• iMC-Panel-GUI

A software panel (i.e., GUI) with large menu area, function buttons, and other controls.

It emulates the iMC-Panel-200.

For more information, please refer to any of the iMC panel user’s guides listed under Applicable

Publications and Tools on page 3.

Imagestore 750 Configuration Overview

The Imagestore 750’s master control option adds additional capabilities to the Imagestore 750’s software architecture which must be configured correctly if all of the devices in the master control system are to communicate with one another successfully.

These are the aspects of Imagestore 750 configuration that relate specifically to master control:

• NV9000’s IP address.

• Channel sources

• Source groups.

• Router salvos

Imagestore 750

User Manual

• Router destinations

• Router sources.

• Intuition XG graphics co-processor providing fill and key signals.

• Channel acquisition and ownership.

• Monitor wall (optional).

Version 1.5, or later, of the Imagestore 750 Configurator is required if you are to support these features.

Configuration of the Imagestore 750’s master control option is described in the following sections and partially involves other components of the iMC master control system (e.g., the NV9000 router control system and the iMC panels). These other components are mentioned where they are part of the steps of Imagestore 750 configuration.

NV9000’s IP Address

The IP address of the NV9000 router control system is an essential part of the Imagestore 750 configuration. Without it, the software cannot configure the sources, destinations and salvos for the router and the Imagestore 750 cannot function in the master control system. The IP address may be a physical IP address (if you have a stand-alone NV9000 system controller), or a “virtual” IP address (when you have a redundant pair of NV9000s).

Note: This document does not address the configuration of the NV9000 router control system. Please refer to the NV9000 documentation, specifically the NV9000-SE Utilities Users Guide, listed under Applicable Publications and Tools on page 3.

Channel Sources

Routers come in many different sizes, from a very few to thousands of sources and destinations. A channel processor might require access to video signals from all of the available router

sources, or (for large routers) a subset of them. The Imagestore 750’s master control configuration allows the required router sources to be included in a list known as the channel sources. These sources are made available for the channel processor to use.

The names (e.g., VTR 23) of channel sources are automatically retrieved from the NV9000 router control system. The NV9000’s source name can be overridden (mapped) in the Imagestore 750 master control configuration by locally defined names. These source names allow iMC control panels to represent router sources in human-readable form on button legends.

 The names of channel sources must be ASCII.

Within the master control configuration, you can define audio gain and audio shuffle presets for each channel source. These allow each source to be independently gain-adjusted or shuffleadjusted to compensate for any upstream audio faults or peculiarities.

Channel sources are updated dynamically following any changes to the router sources in the NV9000 router control system. When the name of a router source changes in the NV9000, the equivalent channel source name is automatically updated on an iMC panel (assuming it was not overridden with a locally defined name). When a router source is deleted from the NV9000, it is still visible on the iMC panel but can no longer be selected. If new router sources are added to the NV9000, they will not be seen at the iMC panel because they are not available in one of the pre-defined source groups.

Master Control

Overview

Source Groups

A source group is a set of sources chosen from all of the available channel sources. They allow iMC panel operators to select between different groups of sources using ‘Group Select’ buttons. When a source group button is pressed, the sources included in that group are mapped onto the program, preset, and aux buttons of the panel.

The Imagestore 750’s master control configuration allows the definition of any number of source groups. The number of entries in each source group is generally chosen to equal the number of panel buttons allocated for sources on the iMC control panel. When a broadcast facility has a mixture of different panel sizes, you can configure source groups of different sizes for use with the appropriate panels. (A source group can have up to 24 entries because the maximum number of source buttons on any panel is 24.)

Sources can be included multiple times within a source group, and the same source can also be used in multiple source groups. For example, the main network feeds can be placed on the leftmost 2 buttons of every source group to make them easier to select in an emergency. There can also be gaps within source groups. Where a source group has gaps in it, the source buttons on the iMC panel are disabled and darkened. Pressing a disabled source button does nothing.

 The names of source groups must be ASCII.

Router Salvos

A salvo is a sequence of router control commands — defined in the NV9000 router control system

— that will execute, in order, when the salvo is invoked either by a button press or a

channel change at a panel. Salvos can be used by iMC panels during a channel acquisition to route the Imagestore 750’s outputs to a monitor wall, or to perform other custom monitoring tasks when the user presses a ‘Salvo’ button on the iMC panel.

Note: Salvos must be defined in the NV9000 configuration software, which is outside the scope of this document. Please refer to the NV9000 documentation, specifically the NV9000-SE Utilities Users Guide, listed under Applicable Publications and Tools on page 3.

Router Destinations (Feeding Program and Preset Inputs)

In the iMC master control system, a router destination is synonymous with an output (from the router) and a router source is synonymous with an input (to the router).

Router destinations and sources are set up during configuration of the NV9000 Router Controller and each may comprise one or more feeds.

A router’s function is to connect its sources to its destinations. The Imagestore 750’s settings for router destinations identify the NV9000’s router destinations

that feed its program and preset inputs. The program bus receives input at the A IN connector. The preset (a.k.a. preview) bus receives input at the B IN connector. The settings represent physical connections between the router and the Imagestore 750.

As a panel operator selects a video source on the program or preset bus of the panel, the Imagestore 750 issues commands to the NV9000 system controller to perform appropriate source switches. Pressing a program source button performs a “hot-cut” of the video source on the channel processor’s program bus. Pressing a preset source button changes the video source on the channel processor’s preset bus showing the source to which the A/B mixer will next transition. All source switches in the router are tallied back to all iMC control panels that own the channel.

Imagestore 750

User Manual

Router Destination (Feeding AUX)

This is a setting that identifies the NV9000 router destination that feeds an auxiliary device such as a waveform monitor. The setting represents a physical connection between the router and the auxiliary device.

As a panel operator selects a video source on the aux bus, the Imagestore 750 issues commands to the NV9000 system controller to perform appropriate auxiliary source switches. In that way, the panel operator controlling an Imagestore 750 has an “extra” set of controls (i.e., the aux buttons) with which to view sources on a monitor, or to route sources to some other device for another purpose. All source switches are tallied back to all iMC control panels that own the channel.

Router Sources (Fed by PGM, PST, CLN, and MON Outputs)

 Note: See the definitions of router sources and definitions under Router Destinations

(Feeding Program and Preset Inputs) above.

These settings identify the NV9000 router sources that are fed by the Imagestore 750’s program, preview, clean-feed, and monitor outputs. Connections to these sources allow the NV9000 system to route the Imagestore 750’s outputs to a local monitor wall.

These settings represent physical connections between the Imagestore 750 and router. Consequently unique sets of sources must be defined for every Imagestore 750 within the Master Control system.

Router Source (Fed by BLACK/SILENCE)

This setting identifies the NV9000 router source that corresponds to black/silence in a video standard that is appropriate for this channel processor. The source allows the NV9000 system to route black/silence to the local monitor wall when gaps appear within the current source group.

Router Source (Fed by USER 1-20)

These 20 settings identify the NV9000 router sources corresponding to custom-defined sources for this Imagestore 750. Such sources can be used to route outputs from a backup channel processor to the local monitor wall, or to view “mirrored” HD/SD channel processors in parallel.

Graphics Co-Processor Feeding Fill and Key

The Intuition XG co-processor (also known as the “slave” device) provides advanced graphics to the Imagestore 750 using one of the 3 available external fill and key inputs. The graphics are then keyed onto the video background signal using any of the 4 available keyers (DSKs). The fill provides the graphics signal, and the key provides the transparency.

You can use the Imagestore 750 configurator to identify which external fill and key inputs receive signals from the Intuition XG. The configuration also specifies to which DSK layer external graphics are assigned and specifies the automatic keying behavior of the assigned DSK as Intuition XG layers cut up and down.

You should also configure the system to allow slave layer states and other system information to be communicated between the Imagestore 750 and the Intuition XG. This can be done over an RS-232 serial connection or over Ethernet.

Master Control

Overview

Channel Acquisition and Ownership

A typical broadcast environment will include multiple channel processors and multiple iMC panels.

Sometimes each channel processor has a dedicated control panel, perhaps with a “super-user” panel operator who is able to take over control of channels in emergencies. Alternatively, panel operators may be responsible for monitoring and controlling several different channels. Flexible arbitration of channel ownership between different panels is therefore provided for master control environments.

The iMC panels have 4 channel acquisition methods (grab, drop, kick, share) to establish ownership of Imagestore 750 channel processors:

• “Grab” — acquire ownership of a channel. A grab can succeed only if the channel is not

already owned by another panel or shared by other panels.

• “Drop” — release ownership of a channel. This method places the panel in a “no channel”

state.

• “Kick” — force the current channel owner(s) to drop a channel. The success of this command

depends on relative panel permissions and the ‘allow kick’ setting of the owning panel.

• “Share” — acquire joint ownership of a channel that is already owned by one or more panels.

The success of this command depends on the ‘allows sharing’ settings of the panels.

Channels can be owned by one panel, or shared by multiple panels if channel sharing is enabled. When a panel already has ownership of a channel, other panels can attempt to kick-off the owning panel to gain sole ownership for themselves. Alternatively, they can attempt to share ownership with the current owner.

A flexible set of panel and channel ownership privileges and permissions allow for the many possible permutations of panel setups at different broadcast facilities.

Each iMC panel is configured with (1) an ownership permission level, (2) rules for being kicked and (3) rules for allowing channel sharing with other panels. Imagestore 750s can also impose kick and share behavior on panels that want to control them based on relative permission levels. This gives a flexible mixture of channel ownership models for different users.

Please see Panel Permissions Configuration on page 91 for further details on channel ownership permissions and other settings.

Monitor Wall

Usually there is a dedicated monitor wall for every iMC panel. This monitor wall is used to view the sources and the channel outputs that are relevant to the local panel.

When a panel acquires a channel, it causes the NV9000 system to make the appropriate router switches so that its local monitor wall shows the appropriate Imagestore 750 outputs (program, preset, clean-feed, and monitor), the current aux bus selection, and all of the sources within the panel’s currently selected source group. This gives the panel operator a complete view of the on-air channel output, any upcoming transitions, and all alternative sources.

Use the MCS Panel Configuration Editor to identify the router destinations that feed the local monitor wall. The router destinations physically connected to the monitor wall.

Monitoring of the channel outputs (program, preset, clean-feed, and monitor) can be achieved in two different ways:

• When a panel acquires a channel, it causes the NV9000 system to make appropriate router

This is the preferred method despite its requiring configuration of both the Imagestore 750

and iMC panel(s). (See Router Sources on page 85 and Monitor Wall Configuration on

page 95.)

• When a panel acquires a channel, it can fire a “channel acquisition salvo” for the channel/

panel combination to make the appropriate router switches for the monitor wall. The disad-

vantage with using salvos is that every existing panel configuration must be updated when

new channels are added to the broadcast facility.

See Applicable Publications and Tools on page 3 for information about software tools.

Hardware Connections

Installing the Imagestore 750 and configuring it to operate with an NV9000 system and iMC control panels is relatively simple if you complete a few specific (and simple) tasks.

Cable Connections

Imagestore 750

User Manual

Installing the Imagestore 750 master control system involves making cable connections and describing those connections in NV9000-SE Utilities, in the Imagestore 750 Configurator, and in various iMC control panel configurations. These are the basic connections:

Fig. 5-2: Master Control System - Cable Connections

The NV9000 system controls an NVISION series digital video router (such as an NV8576 or CR3232-HD). The router provides signals that are controlled by the Imagestore 750. The Imagestore 750 receives commands from automation and master control panels and relays those

Master Control

Hardware Connections

commands to the NV9000 whereupon the NV9000 switches sources to the destinations of interest.

Two of the router destinations must connect directly to the Imagestore 750. The other destinations related to the Imagestore 750 connect to other equipment.

Cable connections are required for each of the following system components:

Note: When you are cabling a channel, please refer to individual documentation for these system components.

Video Connections

• Digital video router (with support for embedded audio).

• NV9000 router control system.

• Imagestore 750 with optional Intuition XG graphics co-processor.

• Automation.

• iMC panel(s).

• Monitor wall(s).

• Configuration PC.

Note: the Imagestore 750’s video connectors are 75W BNCs.

The following video connections must be made when configuring a master control system:

• Connect two of the router’s destinations directly to the Imagestore 750, one to the A input

and one to the B input. A third router destination connects to an auxiliary device.

It is possible to connect the router’s aux destination directly to the Imagestore 750’s C input

which is directed internally to the Imagestore 750’s clean feed or monitor output, if extra

audio processing is required. However, doing this prevents multiple Imagestore 750s from

sharing an auxiliary device.

• If multiple Imagestore 750s are to share a monitor wall, feed the Imagestore 750’s program,

preset, clean-feed, and monitor outputs into the router, as sources, so that they can be used

by the monitor wall.

• Make video connections between the router and monitor wall(s). The number of connec-

tions depends on your system monitoring requirements, the number of monitor walls, and

the number of control panels. There will normally be 4 for the outputs of each Imagestore

750, plus the a number of connections equal to the size of the largest source group for all

panels. An additional connection would be required if you want aux output to appear on the

monitor wall.

It is typical for a master control system to have one monitor wall for each control panel. That

is not a requirement. In any case, the number of connections to any single monitor wall

remains fixed no matter how many channels or panels are present in the system.

• If your Imagestore 750 uses an Intuition XG co-processor, connect the Intuition XG’s fill and

key outputs to one of the fill/key input pairs of the Imagestore 750.

The default IP address is 192.168.7.201 for the primary NV9000’s master control network and

192.168.7.202 for the secondary’s.

If you prefer not to change the NV9000’s master control address, make all other IP addresses

on the master control network part of the 192.168.7.xxx subnet.

 Your NV9000 might have been defined with a virtual IP address. It is preferable to use the

virtual IP address if it has one.

Imagestore 750

2 Connect the Imagestore 750 to master control’s Ethernet switch using Ethernet cable. You

can use either of the two LAN ports on the Imagestore 750. 3 Assign an IP address to the Imagestore 750.

Setup > Network > Gateway Add).

Intuition XG

5 Connect the Intuition XG to the master control Ethernet switch using Ethernet cable.

Assign an IP address to the Intuition XG. (Refer to the Intuition XG publications listed under

Applicable Publications and Tools on page 3.)

The IP address must belong to the master control subnet. If necessary, assign a gateway

address.

Repeat this step for additional Intuition XG co-processors, always selecting unique IP

addresses.

iMC Panels

6 Connect the iMC panel to the master control Ethernet switch using Ethernet cable.

Assign an IP address to the iMC panel using its touch screen (

Setup > Change IP). The IP address must belong to the master control subnet. If neces-

sary, assign a gateway address.

Repeat this step for additional iMC panels, always selecting unique IP addresses.

Panel Settings > IP

Configuration PC

7 Connect a configuration PC to the master control switch and give it an appropriate IP

address on the master control subnet. Also connect a configuration PC to the NV9000 at its

house network port (again with an appropriate IP address). You can use the same PC for

both networks.

At this point, if you have the requisite configuration software installed, it is possible to configure the Imagestore 750(s), the NV9000, and your control panels.

Master Control

Software Configuration

There are various network-related settings that must be configured for master control. These are covered in following sections.

Serial Connections

Note: It is important for serial port settings to be correct at both ends of a serial connection.

Serial Connection to Automation

The Imagestore 750 connects to automation (Presmaster protocol) using an RS-422 serial cable. The Imagestore 750 requires an RJ45 connector at its chosen serial port (COM1– COM4). The following serial port settings are normally recommended between automation and the Imagestore 750:

Please refer to the automation system’s installation guide for information about configuring its serial ports. See Applicable Publications and Tools on page 3.

The Imagestore 750 configuration steps in the following sections refer to the respective hardware device’s configuration applications, as required.

Router Connections

Please see Imagestore 750 Configuration Overview on page 62 for an introduction. First, an NV9000 router controller must already have been set up with valid sources and destina-

tions appropriate for your master control system. Please refer to the NV9000-SE Utilities Guide and to the iMC Master Control Installation Guide. (See Applicable Publications and Tools on page 3.)

Next, establish a network connection to the NV9000 using the Imagestore 750 Configurator. Open the Imagestore 750 Configurator, and either create a new configuration or open an

existing configuration as described in Configuration Mode on page 156.

Master Control

Software Configuration

Choose ‘Configuration Mode’ in the top right drop-down menu. Then, choose the ‘System Settings’ tab and open the ‘Master Control’ branch of the navigation tree at the left:

Fig. 5-3: Imagestore Configurator - Master Control section

1 Specify the router type as NV9000. 2 Enter the IP address on the ‘router address’ field.

This can be a physical IP address (if you have a stand-alone NV9000 system), or a “virtual” IP

address (when you have a redundant NV9000 system). Refer to the NV9000-SE Utilities Users

Guide. 3 Leave the ‘router port’ field as its default. 4 Save and apply the configuration, and wait for the Imagestore 750 to restart. 5 During restart, the Imagestore 750 reads pertinent configuration data from the NV9000. 6 Choose

File > Open and select the Imagestore 750 by its IP address.

7 From the list of all Imagestore 750 configurations, select ‘Active Configuration’ and click OK. 8 Master Control system settings (from the NV9000) are now available to the Imagestore 750

Configurator

It is important to complete these steps before proceeding with other configuration tasks.

The configurator cannot perform certain functions without knowing the NV9000’s IP

address.

Master Control Configuration

 Please see Channel Sources on page 63 and Source Groups on page 64 for an overview.  Before a master control configuration file can be created, router sources must have been

defined on the NV9000. Please refer to the NV9000-SE Utilities Users Guide. (See Applicable

Publications and Tools on page 3.)

The master control configuration file defines channel sources and source groups that the channel processor will be able to control and the owning iMC panel(s) will be able to represent

Imagestore 750

User Manual

on the PGM, PST and AUX buses. The file is stored on the Imagestore 750 separately to the main Imagestore 750 configuration, but is referenced by it.

The following sections describe how to create and edit a master control configuration. You can reopen existing master control configurations to revise them at any time using ‘File > Open > From Device…’.

Note: The master control configuration file can be shared between different Imagestore 750 devices if the same sources and source groups are common to each channel processor.

Channel Sources Configuration

Choose ‘Master Control Mode’ in the top right drop-down menu:

Fig. 5-4: Imagestore Configurator - Master Control Mode

Then choose ‘New’ from the ‘File’ menu. Specify the IP address of the Imagestore 750:

Fig. 5-5: Imagestore Configurator - Specify IP address

When you have done so, a list of NV9000 sources appears:

Fig. 5-6: Imagestore Configurator - Available NV9000 sources

Master Control

Software Configuration

Select some or all of the sources that apply to this Imagestore 750. You can revise the list at any later time.

Save the configuration using the ‘Save’ or ‘Save As’ command from the ‘File’ menu. The chosen sources now appear in the ‘Channel Sources’ view:

Fig. 5-7: Imagestore Configurator - Channel Sources view

Source names allow iMC panels to represent the router sources in human-readable form on their LCD buttons. Initially, the name of each source is automatically retrieved from the NV9000 router control system, but you can override names as required:

1 Select the channel source ID to modify. 2 In the right-hand panel, type the source name that you want in the ‘Name’ field. 3 The ‘Name Generator’ field should automatically change from ‘Use name from router’ to

‘User defined name’.

You can select audio gain and audio shuffle presets for each channel source. (See Gain Mode on page 170 and Shuffle Mode on page 171.) They allow each source to be gain-adjusted or shuffle-adjusted independently to compensate for any upstream audio faults or peculiarities.

Once you have completed all changes needed for the master control configuration, save it onto the Imagestore 750 using the ‘Save As > To Device…’ in the ‘File’ menu.

Channel Source Templates

When you want to apply audio gain and shuffle presets repeatedly to different sources, you can simplify repetitive channel source configuration by using channel source templates.

Imagestore 750

User Manual

Begin by choosing non-default gain and shuffle presets (as you require) in one of the channel sources. In the following example, the source is attenuated by -3dB, and a stereo swap shuffle is applied.

Fig. 5-8: Imagestore Configurator - Channel Soure template

Right-click on the modified source (highlighted, in the center pane) and choose ‘Copy settings to source template…’:

Fig. 5-9: Imagestore Configurator - Copy Settings

Name the source template accordingly:

Fig. 5-10: Imagestore Configurator - Naming Source Template

Master Control

Software Configuration

This new source template now appears in the ‘Source Templates’ list in the left-hand panel. The template’s audio parameters, name, and color scheme can be adjusted in the right-hand panel:

Fig. 5-11: Imagestore Configurator - Source Templates

Select the sources to which you want to apply this template, then right-click a source and choose ‘Assign source template’:

Fig. 5-12: Imagestore Configurator - Apply Source Template

The sources selected above now shows the template name in the ‘Source Template’ column, and the template color scheme also helps identification. Notice that the audio parameters are greyed out because they follow the source template:

Fig. 5-13: Audio parameters greyed out, follow Source Template

Imagestore 750

User Manual

When the source template is adjusted later, all channel sources using the template will be updated to match. This can be very useful if hundreds of sources require the same audio adjustment.

To revert to prior audio parameters, select the channel source(s), right-click a source, and select ‘Break association with source template…’:

Fig. 5-14: Imagestore Configurator - Break Association with Source Template

A confirmation dialog appears:

Fig. 5-15: Imagestore Configurator - Break Association with Source Template - Confirmation dialog

Click ‘Yes’ to confirm a break in association with the source template, or ‘No’ to keep the template association.

Source Groups Configuration

Although source groups are defined in the Imagestore 750 configuration, they are for the use of iMC panels.

Create source groups by right-clicking within the ‘Source Groups’ tab in the left-hand panel under ‘Master Control Mode’. There are two options; ‘New…’ and ‘Auto assign…’:

Fig. 5-16: Imagestore Configurator - Create New Source Group

Master Control

Software Configuration

The ‘New…’ option asks you to enter a name and the number of entries for the new source group:

Fig. 5-17: Imagestore Configurator - Source Group Name (ASCII)

When the group is created, you will see a list of sources and “slots” for sources at the bottom of the window. The slots correspond to iMC panel source buttons.

To assign sources to the buttons, click-and-drag sources from the list to the slots. You can drag multiple sources into contiguous slots:

Fig. 5-18: Imagestore Configurator - Source Groups

It is acceptable to leave some slots unassigned, creating gaps. It is also acceptable to have the same source in more than one slot.

The ‘Auto Assign…’ option generates a series of sources groups that cover all available sources. When you choose this option, a dialog asks you to enter a name prefix and the number of sources in the source groups that will be generated:

Fig. 5-19: Imagestore Configurator - Source Groups Prefix

Imagestore 750

User Manual

You will then be informed how many source groups will be generated. This is a sample:

Fig. 5-20: Imagestore Configurator - Source Groups Created

In the example above, two source groups (Group 1and Group 2) were automatically created using sources 1–16 and 17–19. The source group mappings can then be modified.

Source group dependencies between the Imagestore 750 configuration and the iMC panel configurations must be considered. When panels that have different numbers of source buttons are to be supported by the same channel, a mixture of source group sizes can be defined accordingly.

For example, 32 sources might require 6 source groups when an iMC-Panel-300 and an iMCPanel-200 are used to control the same channel:

Two 16-entry source groups (1–16, 17–32) for the (larger) iMC-Panel-300.

Four 10-entry source groups (1–10, 11–20, 21–30, 31–32) for the (smaller) iMC-Panel-200.

Panels then must be configured to use the appropriate sized source groups. After you have completed all changes needed for the master control configuration, save the

configuration in the Imagestore 750 using the

File > Save As > To Device....

Master Control

Software Configuration

Master Control Configuration Cross-Reference
