Overview
Introduction
This introduction provides a basic overview of the concept of the unit and
includes instructions for getting started.
An extensive range of options and upgrades are available for Imagestore 750
and this section describes the purpose and features of each enhancement.
More detailed and specific information regarding operation, configuration,
installation, the web interface, operation with Dolby and support are provided
in later sections.
Imagestore 750 (Product code IS-750) is part of Miranda Technologies Inc.'s
professional broadcast equipment range of products and its primary use is to
insert up to four logos into either SD-SDI or HD-SDI digital video signals.
The capabilities of this 1RU unit include simple logo insertion, still and
animated images. The Imagestore 750 can be purchased with Dolby options
to enable enhanced audio features.
Applications
Imagestore 750 is typically used to mix between different program feeds and
to insert a still or animated logo, channel identification, a programme
schedule, an advertisement, an emergency image, or a combination of any
four of those. Each of these resources may be brought on-air from the image
library of up to 4000 images. Alternatively, up to three separate external 'live'
fill and key signals (from a character generator, or a still/animation store) can
be directly inserted into the SD-SDI or HD-SDI signal via any of the four
keying layers.
Imagestore 750 is also fully compatible with the Presmaster Control System
and panel to create a Master Control environment.
Miranda Technologies Inc. Page 35

IS750 Block Diagram – Main Signal Paths
There are line FIFOs on each SDI video input, feeding 2 Video Channel
Blocks (Program and Preview) and one parallel Audio Processing block.
Each video channel has and AB Mix and 4 keyers which may be fed from up
to 3 external Fill/Keys or one of 4 internal stores and an optional dualchannel DVE.
Still (.oxt), animated and Easytext (.oxa) images are typically stored in the
unit's storage library (compact flash or hard disk, depending upon the option
purchased) and then loaded into the internal stores. Images may be added to
the library using a USB stick but the files must be in an appropriate format.
Miranda Technologies Inc.'s Media Conversion Software is designed for this
purpose and is supplied with each Imagestore 750.
An Ethernet interface provides for the rapid loading of images and
animations over a 100BaseT network using Media Conversion Software
Page 38 Miranda Technologies Inc.
Page 39
Imagestore 750 User Manual Overview
(MCS). This interface also enables the transfer of images between a PC
workstation and Imagestore using Miranda Technologies Inc.'s Vertigo
Xplorer product. This software provides for transfer and management of stillimages and animations. Files may also be transferred using a secure FTP
program.
A fail-safe mechanical Video Relay Bypass option is available that directly
connects the A and C video input sources (see block diagram below) to the
program and preview outputs in the event of a power supply problem.
Video Architecture
Each of the 2 video channel blocks within the Imagestore 750 contains an AB
Mixer and 4 Keyers, overlaying either internal or external media onto
background video (from 4 stores and/or up to 3 external Fill/Key inputs).
The video architecture is depicted below:
There is a DVE option that equips each video channel with a dual-channel
DVE. The DVE may be inserted at more than one point in the Keyer chains.

Imagestore 750 User Manual Overview
Getting Started
Applying Power
Before applying power, ensure that the USB port does not contain a USB
stick. Each of the two power supply units (PSU) on the Imagestore 750
contains a power switch accessible by removing the front facia. The product
should be connected to the mains via an appropriate circuit breaker on each
circuit.
Boot-Up Sequence
Once power is applied, Imagestore 750 will boot automatically and the
normal complete boot process takes about 50 seconds (approx 90 seconds
after a software upgrade).
Before booting normally, the unit first checks to see if there is a USB stick in
the USB port and, if it finds one, it will attempt to boot from that disk.
Miranda Technologies Inc. issues specialised USB sticks for use as part of
the software upgrade boot-up sequence. No other USB stick should ever be
inserted. The upgrade procedure is covered later in this manual.
The normal boot sequence is complete when the following top level "bootup" menu appears on the front panel display.
Note: When a restart is required to change settings such as the video
standard, then a Software Reset can be used. Since this option
will usually complete in approximately 16 seconds it is much
faster than Restart System.
Miranda Technologies Inc. Page 41

Facilities and Features
Image Loading and Distribution
The entry-level Imagestore 750 provides storage for up to 4000 full-screen
images with their associated keys. Each animated clip is counted as one
single image stored in the library. With large or long duration animations
(where the total pixel count of the animation exceeds one full-screen frame)
the total number of full screen frames used counts towards the permitted
maximum of full-screen images in the library.
Images (.oxt), animations and Easytext (.oxa) files saved to a USB stick from
Miranda Technologies Inc.'s Media Conversion Software (or other Miranda
Technologies Inc. units) can be loaded via a USB key or network transfer.
Note that to save or load media to/from a USB stick, the USB stick needs to
have been DOS formatted.
Miranda Technologies Inc. also provides an image transfer and management
system for Imagestore 750. The Xplorer software uses a local area network to
connect the workstation to a number of Miranda Technologies Inc.'s image
and audio insertion products. Details of Xplorer are contained in a separate
manual user guide.
Image Editing
The image editor permits an operator to position an image/animation (both
horizontally and vertically), mask the image/animation and adjust the clip,
gain and transparency levels prior to transmission.
Transmission
Once prepared, an image/animation can be saved in the image library and
sent to air using fade and cut transitions.
Animated Images
Imagestore 750 provides image animation, for applications such as moving
logos, messages and emergency images. The image motion system provides
Page 42 Miranda Technologies Inc.
Page 43
Imagestore 750 User Manual Overview
storage and live playout for up to 4000 full or part-screen images of variable
duration.
The maximum animation length is dependent upon the screen-size of the
images, the playout memory installed in the Imagestore 750 (512MB or 2GB)
and the amount of that memory allocated to the associated keyer.
There are four video stores, which may be used to hold text, stills or moving
logos. The images may be any size up to full screen. Stored images and their
associated keys are stored and processed at 10 bit resolution (unless the
image is stored without key to save space in which case it is stored at 8 bit
resolution.)
The time of larger animations, up to full screen, is reduced proportionally to
the area used. Areas are evaluated each frame so animations may change in
size with no penalty.
With 128MB of playout memory per store, a logo of ¹/64 screen size can be
animated for just over half a minute. Larger screen sizes or smaller playout
memory sizes affect the maximum animation time pro rata.

Moving images are constructed from component images using the Animation
Builder software provided as part of the Media Conversion Software (MCS)
package supplied with Imagestore 750.
Component images are imported into the animation builder utility from 32-bit
Targa image files thus allowing components to originate from almost any
computer graphics system.
Miranda Technologies Inc. Page 43

Overview Imagestore 750 User Manual
AB Mixer
The integral AB Mixer video switcher is designed to be fed by any of the
unit’s input sources or by an external router under automation control. The
mixer provides cut, cross and V-fade transitions with variable fade rates.
Timing, Control and Automation
Imagestore is designed to be easy to install. One line FIFO’s are provided on
each input for simplified system timing.
Other valuable set-up and control features include a menu-driven front panel
display, a General Purpose Interface (GPI) macro editor and a facility to load
(or save) configuration settings from (or to) a USB stick.
Imagestore 750 is highly suited to automated broadcast environments and
remote control options include RS422/RS232, as well as GPI.
Mechanical Bypass
In the event of power loss to the Imagestore 750, or failure of both internal
power supplies, the mechanical video relay bypass routes the serial digital
“background signal” “A In” directly to the Program output “PGM” and “C
In” to Preview output “PVW”.
This feature is an emergency failsafe and is completely non-synchronous in
operation. During boot-up, the bypass is maintained until Imagestore 750 is
fully operational. At switch-over a glitch in the video is to be expected.
Emergency Alert System
Imagestore 750 supports Emergency Alert Systems providing the relevant IS750-EAS licence is installed. The two supported EAS receivers are:
• Sage ENDEC Model 1822
• TFT EAS 911T
To configure a communication port to accept the EAS data stream refer to the
Serial Comms Setup section on page 176. For more information about EAS
please refer to page 235.
Page 44 Miranda Technologies Inc.
Page 45
Imagestore 750 User Manual Overview
2D DVE (PGM and PVW)
Both of the 2D DVE licence options provide the Imagestore 750 with
independent control of DVE sequences on Program (PGM) and Preview
(PVW) channels. The IS-750-DVE option enables a single DVE window per
channel, and the IS-750-DVE-DUAL option enables two DVE windows per
channel.
These options are capable of digital video effects on any of the input video
streams or AB Mixer output, making them ideal for picture-in-picture
applications such as over the shoulder news transitions, as well as squeezes
for credits, news flashes, sports results and schedules.
Clock Insertion
The Bugclock option (IS-750-Clock) allows Imagestore 750 to insert
customised in-vision clocks. A wide range of clocks and timers can be
generated, with hour, minute and second indications. Fully customised clocks
can be produced offline using the Clock Builder application (part of the
Media Conversion Software (MCS) package). Bugclock can be locked to
station LTC or VITC timecode. Clocks are loaded, previewed, positioned and
keyed in the same way as animations and static logos.
Bugclock images behave like all other images with respect to positioning,
transparency and masking controls. Previewing behaviour is the same as with
other clips and images and will show the clock running where appropriate
All existing GPI and automation commands, that apply to still images and
animations, function identically for clocks.
Bugclocks like other images use a single keying layer. This means that a
clock can be previewed while a different clock is shown on program.
Miranda Technologies Inc. Page 45
Page 46
Overview Imagestore 750 User Manual
Embedded Digital Audio Mixer
The optional Easysound digital audio mixer (IS-750-Audio6 or IS-750Audio16) can be enabled within Imagestore 750 and is designed to add voiceovers, jingles and other audio inserts over a program soundtrack at
transmission. Easysound can also accept audio from AES/EBU sources, as
well as embedded audio from the Imagestore's background video input. The
mixes are available on AES/EBU outputs and can also be re-embedded into
the SDI program output.
Switching Dolby E Signals
When operating in a progressive video standard (either 720p at50Hz or 720p
at 59.94Hz) and switching Dolby E signals, the Imagestore 750 must be
given an interlaced reference input – (1080i tri-level or SD bi-level analogue
reference) – and the Dolby E data must be aligned to this. This is because
Dolby E data is locked to the interlaced frame.
• 720p @ 59.94Hz = 59.94 Hz frame rate
• 1080i @ 59.94Hz = 29.97 Hz frame rate
This applies to all Imagestore 750 units that receive Dolby audio data,
whether or not any Dolby decode/encode options are enabled. Units without
Dolby options enabled are able to cut-switch between Dolby data streams,
with the transition occurring at the mid-point of an AB mix.
Digital Audio Storage
Easyplay options (IS-750-EP2 or IS-750-EP8) allow digital audio storage and
playout for Imagestore 750. With Easyplay, broadcasters can associate
sounds to image files, creating a whole new range of possibilities for musical
logos and sound enhanced captions. Easyplay requires the Easysound option
to be enabled and the system may be networked with the Media Distribution
System.

Imagestore 750 User Manual Front Panel Operations
Front Panel Operations
This section of the manual explains, on a task-by-task basis, the operation of
an Imagestore 750 using only the front panel controls. Each task is fully
detailed, making reference to other sections unnecessary.
Controls
All Imagestore 750 operational and configuration features can be monitored
and controlled from the front panel of the unit using the joystick and display.
A simple menu-driven procedure provides access to the operational,
configuration and set-up options.
The front panel of Imagestore 750 contains a USB port, a four-position
joystick and a front panel LCD display. Local control of the unit is "menu
driven" using a combination of joystick movements together with options
displayed on the front panel. Joystick up is identified on the panel as escape
and joystick down is identified as enter. Left and right joystick moves ⊳
are used to move a cursor left and right accordingly to select menu options.
To the right of the Joystick is a small hole, behind which there is a button
used to reset the system (not recommended) or perform a software update
recovery (see page 394).
Front Panel Display
The alphanumeric front panel display is divided into two separate lines.
• The upper row of characters indicates the function
• The lower row indicates the current selection and any optional
configuration changes that are available.
Miranda Technologies Inc. Page 51

- Intermediate state, transition being processed.
↑Image/voice-over keyed up (to air)
↓Image/voice-over keyed down (from air)
B Fade to Black
S Fade to Silence
Escape and Enter Joystick Selections
Selecting escape is used to proceed to a menu option closer to the boot-up
menu. Successive pressing of escape will bring the display to the start-up
menu.
Selecting enter is used to accept the menu item currently shown as selected
by being enclosed in brackets.
Left and Right Joystick Arrows
Left and right joystick arrows ⊳ may be used to index left and right
respectively along a displayed menu branch to select a function. When a
selection of parameters is offered, these keys may be used to select a
variable. Where a single value is displayed the left arrow may be used to
reduce the displayed value and the right arrow may be used to increase it.

To adjust the input mask values for an input, select it using the joystick
arrows ⊳, and press enter. Pressing enter after adjusting the Bottom value
will accept all changes made. Pressing escape prior to this returns all settings
back to their previous values.
Warning: Setting masks will directly affect the equivalent SDI source,
so anything else that uses that source (for example, the AB
Mixer or a DVE Input) will be also affected.
If an input is associated with a colour field or test pattern (so
that it is not using its SDI input source), then the image will
not be masked. Only the SDI source is masked.

Note: Pressing enter will activate the transition.
A CUT transition is an instant switch to the selected source. By default this is
achieved between frames in the vertical interval so the active picture is
allowed to finish before the new data is transmitted, but other cut options are
also possible – (see page 68).
A FADE transition is the gradual process of switching to the selected source
with rates adjustable between 1 and 999 fields (16.65 seconds at 60Hz). By
default fades begin between frames in the vertical interval, but this can be
adjusted (see page 68).
The front panel display will identify the background video source. Either A
or B will appear on the top line of the display depending on which is active.

Both of the 2D DVE licence options provide the Imagestore 750 with
independent control of DVE sequences on the Program (PGM) channel. The
IS-750-DVE option enables a single DVE window. The IS-750-DVE-DUAL
option enables two DVE windows.
These options are capable of digital video effects on any of the input video
streams or AB Mixer output, making them ideal for picture-in-picture
applications such as over the shoulder news transitions, as well as squeezes
for credits, news flashes, sports results and schedules.
The DVE delay is exactly 2 interlaced fields or 2 progressive frames. For
59.94Hz standards the delay is 2/59.94 s and for 50Hz standards the delay is
2/50 s.
Any non-active picture data in the DVE input stream is also delayed whilst
the video is resized. Embedded audio is delayed in the Audio Engine.
If the DVE is not required for that channel it can be completely taken out of
circuit by setting the DVE mode to bypass. This will remove the delay
completely.
Using the DVE editor software up to 97 sequences can be loaded onto the
Imagestore 750 for later playback. The DVE editor software and manual is
supplied on the MCS CD.

DVE Mode
The following DVE modes can be selected altering the video path within the
system. Modes can be set independently for program (PGM) and preview

With DVE enabled, the DVE mode is in circuit and active. DVE
compensating Video delay is in circuit.
The inputs for each DVE channel are defined via the DVE 1 Input and DVE 2 Input menus (see page 73), thereby giving a large number of possible DVE

Set Key Params
Keying is the process of inserting one video signal (referred to as the Fill
signal) into another video signal (referred to as the Background signal)
according to a third signal (referred to as the Key signal). There are two
separate processes to consider
• Generating the Key signal
• Using the Key signal
Oxtel series products implement keying where the Key is contained in the
luminance content of the SDI signal. The Key source is selected from either
the Fill input (known as Self Key) or a separate Key signal. Once selected,
the Key signal is processed with Clip, Gain and Transparency to alter the
mapping function between Key input luminance to Key output values.
Transparency modifies the maximum key value in the range 0 to 1.
Once generated, the Key signal controls the combining of the Background
and Fill video signals. Oxtel series products support both Linear and Full
keying.
Key invert replaces the Key output with 1-Key, thereby inverting the action
of the Key.
Linear keying is used 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
external to the Imagestore 750. Then the Imagestore 750 computes (1-Key)
Page 82 Miranda Technologies Inc.
Page 83
Imagestore 750 User Manual Front Panel Operations
and uses this to “cut a hole” in the Background signal and the Fill is then
simply added to this.
An example of this is where the output of a signal generator requires high
quality keying. If a Full key was used it may cause a darkened border around
characters where the character edge on the Fill signal correlates with the
character edge on the Key signal and the resultant Fill signal after
multiplication would be parabolic.
Full keying is where the Fill signal needs to 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 external to the Imagestore 750. Then the
Imagestore 750 cuts a hole in the Fill with the Key and then cuts a hole in the
Background with a computed (1-Key) signal. The cut Fill and cut
Background are then added together.
Miranda Technologies Inc. Page 83
Page 84
Front Panel Operations Imagestore 750 User Manual
Source
Self key: When the source option is set to self, the key data is derived from
the luminance content (Y value) of the "Fill" signal itself.
Separatekey: When the source option is set to separate, the key data is
derived from the luminance content (Y value) of the separate "Key" image.
None: When the source option is set to none the key for an image is set to
white so that there is no image transparency.
Type
Full Key is where the foreground image (Fill) is passed only where the key
signal is present.
Linear Key is where the background and foreground (Fill) are summed and
the foreground (Fill) is unaffected by the key.
Sense
Normal, a black-level key signal that will cause the "Fill" image to be fully
transparent and not appear over a background. A white-level key signal will
cause the "Fill" image to be opaque with no background appearing through.
Intermediate keying levels will produce a pro-rata transparency effect.
Invert reverses this effect and white-level key signals now create a fully
transparent "Fill" image with black-level signals producing an opaque "Fill"
image.
Masking
Defines a mask area for the keyer. The number range is determined by the
width and height of the image in pixels, and is limited by the selected
standard. To maintain correct YUV values the pixel count will increment in
units of 2. Anything fed into the keyer (i.e. external fill and key, and the
output from the stores) can be masked. Note that if viewing the stores on the
monitor output, they will not be masked as the masking is now done in the
keyer rather than in the store.

C, G & T (Clip, Gain & Transparency)
Clip
Clip is the level under which the key signal will be forced to black. In a
keying process this will result in a total absence of fill video in areas where
the incoming key signal is less than the clip level.
Gain
The gain level amplifies the key signal, forcing grey levels towards and up to
white. In a keying process this will result in the fill signal being less
transparent than it otherwise would be in areas with a grey key signal.
Miranda Technologies Inc. Page 85
Page 86
Front Panel Operations Imagestore 750 User Manual
Transparency
Transparency controls the luminance content (grey scale value) of the key
signal and therefore the amount of background video that will 'seep' through
the keyed image.
Typical CGT Values
For optimum results set the CGT values to the following:
• Clip 64 (Black level)
• Gain 940 (Peak White)
• Transparency 512 (Fully opaque)
Clip and Gain values are in the range of 64 (black) to 940 (white).
Transparency is in the range of 0 (clear) to 512 (opaque), and can be adjusted
using the joystick arrows ⊳.
