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 and
this section describes the purpose and features of each enhancement.

More detailed and specific information regarding operation, configuration,
installation and support are provided in later sections.

Imagestore (Product code IS2) is part of Miranda Technologies Ltd's
professional broadcast equipment range of products and its primary use is to
insert logos and audio into a SDI digital video signal. The capabilities of this
compact unit extend well beyond simple logo insertion and, in addition to
still, animated and clock image insertion, its capabilities may be extended to
include digital audio mixing, storage and play-out.

Applications

Imagestore is typically used to insert a still or animated logo, a channel
identification, a programme schedule, an advertisement, an on-screen clock,
an emergency image, or a combination of any two of those. Each of these
resources may be brought on-air from Imagestore's 400-image memory
(optionally 2000 or 4000 image). Alternatively, external 'live' fill and key
signals from a character generator, or a still/animation store, can be directly
inserted into the SDI signal.

A dedicated remote control panel is available and one or more remote
controllers can operate multiple Miranda Technologies Ltd products when
used with the optional Intelligent Pane l Router.

Dual stereo pair voice-overs can be performed using the Easysound optional
digital audio mixer. The Easyplay upgrade to Easysound provides for the
play-out of library audio with images. Full details of the Easysound and
Easyplay options are given in a the Easysound Audio section of this manual.

Overview Imagestore User Manual

Page 26 Miranda Technologies Ltd

Concept

Imagestore may be set up for operation in one of two modes, Swap Preview
and Cascade. These two modes use the internal keyers in a different
configuration and provide differ ent operational characteristics.

In either mode a fail-safe mechanical by-pass option is available that directly
connects the background video to the programme output in the event of a
power supply problem.

Still, animated and clock images are typically stored in the unit's hard disk
library. Images may be added to the library using the floppy disk drive but
the files must be in an appropriate format. Miranda Technologies Ltd's Media
Conversion Software (MCS), designed for this purpose, is supplied with
Imagestore.

An Ethernet interface provides for the rapid loading of images and
animations over either a co-axial or twisted pair network using MCS. This
interface also enables the transference of images between a PC workstation
and Imagestore using Miranda Technologies Ltd's MS Windows NT™ based
Media Distribution System (MDS). The MDS software provides for transfer
and management of still-images, animations and clocks.

Imagestore Solo

Imagestore Solo is an entry-level product, software limited to a single keying
layer and permanently set in Swap/Preview Mode. The keyer can be
previewed on the Preview monitor, which is also used to view the Edit Pack
options of Polyphoto, Playlist and Image Clean-up.

Imagestore Solo is NOT Presmaster compatible but does support all other
standard Imagestore sales options including the A/B Mixer, Squeezy
Easyplay, Oxtel RCP etc.

Imagestore Solo can be upgraded to an Imagestore 2. For full details on how
to upgrade please consult your local Miranda Technologies representative.

Imagestore User Manual Overview

Miranda Technologies Ltd Page 27

Swap-Preview Mode (IS2 - Solo)

Swap-Preview Mode Concept

In Swap-Preview mode, the two keyers work in parallel, as shown above.
One keyer operates exclusively as a dedicated preview and image edit device
within a preview channel while the main keyer provides programme output.

This configuration of keyers allows any of the images in the hard disk image
library to be previewed and edited without affecting the programme output.
The standard SDI preview output may be replaced with an optional analogue
PAL/NTSC output although this option uses an 8-bit DAC and is intended for
monitoring purposes only.

The preview output may also be used to view system information and, where
the Edit Pack option is installed, thumbnails of the library images.

Cascade Mode Concept

In Cascade mode the two keyers are arranged in series as shown above. This
configuration allows two images to be keyed simultaneously, but
independently, over the background video. Cascade Mode provides a more
restricted preview capability whilst still providing the ability to view images
prior to transmission.

Imagestore User Manual Overview

Miranda Technologies Ltd Page 29

Getting Started

Applying Power

Before applying power, ensure that the floppy disk drive does not contain a
disk.

Imagestore does not have a power on/off switch and power is applied
immediately when the IEC plug is connected to mains power. The product
should be connected to the mains via an appropriate circuit breaker.

Boot-Up Sequence

Once power is applied Imagestore boots automatically and the complete
process takes about 50 seconds. The unit first checks to see if there is a disk
in the floppy drive and, if it finds one, it will attempt to boot from that disk.
Miranda Technologies Ltd issues specialised floppy disks for use as part of
the boot-up sequence when software upgrades are being implemented. No
other disk should ever be present in the floppy disk drive during the boot
sequence. The boot sequence is complete when the following top level "boot­up" menu appears on the front panel VFD display.

Facilities and Features

Image Loading and Distribution

Entry-level Imagestore provides storage for up to forty full-screen images
with their associated keys and this can currently be upgraded to 400, 1000,
2000 or 4000 frames. 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 full­screen images in the library.

Imagestore can import TARGA and JPEG images directly from DOS­formatted floppy disks. The imported images are copied directly to the
preview channel and also saved within the internal image library.

Images, animations, clocks and audio files saved to floppies from Miranda
Technologies Ltd's Media Conversion Software - (or other Miranda
Technologies Ltd units) can be loaded in the same way. The Media
Conversion software allows large animations and images to be saved across
multiple floppy disks, using loss-less compression to reduce the number of
disks required.

Frames may be grabbed from SDI video using the Fill and Key ports. An
image clean-up feature to remove inter-field flicker forms part of the "Edit
Pack" option.

Miranda Technologies Ltd also provides an image transfer and management
system for Imagestore. The Media Distribution System (MDS) is based on a
pre-loaded and pre-configured PC workstation. A local area network can
connect the workstation to a number of Miranda Technologies Ltd's image
and audio insertion products. Details of MDS 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.

Imagestore User Manual Overview

Miranda Technologies Ltd Page 31

Transmission

Once prepared, an image/animation can be saved in the image library and
sent to air using cut and fade transitions.

Animated Images

Imagestore provides image animation, for applications such as moving logos,
messages and emergency images. The image motion system provides storage
and live playout for up to 40, (optionally 400,1000, 2000 or 4000) full, or
part-screen images of variable duration.

The maximum animation length is dependent upon both the screen-size of the
images and the playout memory installed in the Imagestore. With 128MB of
playout memory, a logo of ¹/

64

screen size can be animated for up to 3
minutes. 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 package
supplied with Imagestore.

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.

Polyphoto, Playlist and Image Clean-Up

The Edit Pack option provides the additional features of polyphoto, playlist
and image clean-up.

Polyphoto provides for the viewing of image library thumbnails at the
preview output whilst Playlist enables an ed itable sequence of images to be
created. Image clean-up provides interpolated and algorithmic image clean­up functions used to remove inter-field flicker caused by grabbing images.

In order to view polyphoto images a monitor must be connected to the PVW
(preview) output of the Imagestore. The preview output may either provide a
digital or analogue output signal and the monitor attached must be
appropriate. The polyphoto feature may only be used when Imagestore is
configured for Swap-Previ ew mode and is not available in Cascade mode.

Overview Imagestore User Manual

Page 32 Miranda Technologies Ltd

Control of Polyphoto, Playlist and Image clean-up features may only be
achieved using a Miranda Technologies Ltd remote controller, Oxtel RCP.

Clock Insertion

The Bugclock option allows Imagestore 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 (part of the MCS Media Conversion software 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.

A Bugclock image uses a single layer of the system it runs on. This means
that a clock can be previewed while a different clock is shown on
programme. In Cascade mode, two different clocks can be displayed
simultaneously.

Squeezy Digital Video Effect (DVE)

Squeezy DVE is a single-channel 2D DVE. It is designed for picture-in­picture applications such as over the shoulder news transitions, as well as
squeezes for credits, news flashes, sports results and schedules.

Imagestore User Manual Overview

Miranda Technologies Ltd Page 33

AB Mixer

The AB Mixer integral AB video switcher is designed to be fed by an
external router under automation control. The switcher provides cuts, wipes
and fade transitions with variable fade rates.

Embedded Digital Audio Mixer

The optional Easysound digital audio mixer can be fitted within Imagestore
and is designed to add voice-overs, jingles and other audio inserts over a
programme soundtrack at transmission. Easysound can accept audio from
AES/EBU sources, as well as embedded audio from the Imagestore's
background video input. The four mixes are available on AES/EBU outputs
and can also be re-embedded into the SDI programme output.

Digital Audio Storage

Easyplay is the digital audio storage and playout option for Imagestore. 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 fitted to Imagestore and the
system may be networked with the Media Distribution System.

Timing, Control and Automation

Imagestore is designed to be easy to install. One line FIFO's are provided on
each 270Mb/s SDI input for simplified system timing. An external system
reference may be used to provide high stability system timing and system
integrity.

Other valuable set-up and control features include a menu-driven front panel
VFD display, a General Purpose Interface (GPI) macro editor and a facility to
load configuration settings from, and save system configurations to, a floppy
disk.

Imagestore is highly suited to automated broadcast environments and remote
control options include RS422/RS232, as well as GPI and analogue fader
inputs.

Overview Imagestore User Manual

Page 34 Miranda Technologies Ltd

Remote Control Panels

Miranda Technologies Ltd offers a versatile remote control panel for use with
Imagestore which include alphanumeric displays, menu driven soft-keys and
multiple dedicated keys.

The Oxtel RCP can provide for control of all Imagestore's functions. Each
key can be individually disabled so that, for example, accidental "fade-to­black" could be prevented. Contact the Miranda Technologies Ltd helpdesk
for full details.

Remote control panels can be built into a desk or mounted into a 19" rack­mount frame using the RMF-001 option, which holds up to two panels. A
blanking panel, RMF-001-BP, is required where only one co ntrol panel is to
be mounted in the RMF-001 frame.

To save space and simplify control, the remote control panels can control
more than one Imagestore when used with the Intelligent Panel Router (IPR).
The IPR also allows a single Imagestore to be controlled by multiple remote
control panels in different l ocations.

Mechanical Bypass

In the event of power loss to the Imagestore, or failure of an internal power
supply, the mechanical bypass option routes the serial digital "background
signal" directly to the programme output. This feature is an emergency
failsafe and is completely non-synchronous in operation. During boot-up, the
bypass is maintained until Imagestore is fully operational.

Options

Status information regarding the options included with each Imagestore can
be accessed from the front panel display, using the panel control keys as
described later in this guide.

The following table lists the options with their identifying codes and briefly
describes the purpose.

Front Panel Operations

This section of the manual explains, on a task-by-task basis, the operation of
the Imagestore using only the front panel controls. Each task is fully de tailed,
making reference to other sections unnecessary.

Controls

All of Imagestore's operational and configuration features can be monit ored
and controlled from the front panel of the unit using the pushbuttons and
display. A simple menu-driven procedure provides access to the operational,
configuration and set-up options.

The front panel of Imagestore contains a 3½ floppy disk drive, four push­button control keys and a vacuum fluorescent display (VFD). Local control
of the unit is "menu driven" using a combination of the push-button keys
together with options displa y ed on the VF D. The upper key of the group is
identified on the panel as the escape key and the botto m key is identified as
the enter key. Left and right keys W X are used to move a cursor left and
right accordingly to select menu options.

VFD Display

The alphanumeric VFD display is divided into two separate lines. The upper
row of characters indicating the function and the lower row indicating the
current selection and any optional configuration changes that are available.

Where there are more options available than there is room for on the display,
the symbols < and > are used to indicate that other options exist to the left

and right respectively. Using the appropriate arrow key will reveal those
options.

VFD tallies (mixer/keyer states)

To highlight the state of either the mixer or the keyer, additional symbols are
shown on the top line of the VFD display at the right hand edge. These
symbols represent:

A source A
B source B

- intermediate state, transition being processed.
↑ image keyed up (to air)
↓ image keyed down (from air)

B Fade to Black

Escape and Enter Keys

The escape key is used to proceed to a menu option closer to the boot-up
menu. Successive pressing of the key will bring the display to the start-up
menu. The enter key is used to accept the menu item currently shown as
selected by being enclosed in brackets.

Left and Right Arrow Keys (W X)

Left and right arrow keys W X may be used to cursor 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 key may be used to
reduce the displayed value and the right key may be used to increase it.

Common Mode Operations

Imagestore's top-level menu provides the option to choose either manual
(operations) or set-up (configuration). When manual is selected the Manual
Override menu is revealed. Sub-menus accessed through the operate option

Setting A/Bgnd, Fill and Key Inputs

Imagestore has three digital video input signals, identified as A/Background,
Fill and Key. The user has the option to set each of these inputs so that it
either accepts external SDI video signals or an internally generated test
colour field is inserted at that input.

To check the status of the input settings or to change any settings, select the
set-up option from the boot-up menu and, using the arrow keys W X, displa y
the set inputs option. Press the enter key to apply that selection.

Three options are made available, A/Background, Fill and Key. Use the arrow
keys W X to select the appropriate input and then press the enter key to
apply that selection. In each case the display will indicate whether SDI video
or colour is currently selected.

To change the current setting, use the arrow keys W X to select the choice
and press the enter key to apply the selection.

If the SDI video option is selected but no signal is present at that input, the
input defaults to colour field with a value determined by the colour field
settings.

When the Colour option is applied, the user is presented with three
adjustments in turn, which together set the colour of the field to be inserted.
The first adjustment only affects the red component of the field.

Imagestore User Manual Front Panel Operation

Miranda Technologies Ltd Page 41

Using the left and right arrow keys W X the percentage value may be
changed. Pressing the enter key will apply that setting and bring up a similar
adjustment for the green colour field. Having set the percentage of green,
pressing the enter key will bring up a similar adjustment for the blue colour
field. Pressing the enter key from the blue field adjustment completes the set­up and the menu is returned to the Input Signal Set menu.

Emergency to Air

Imagestore has an emergency image facility, which, in the event of a
background video failure, enables an operator to rapidly get a preset
emergency image to air. The emergency image is stored in the image library
under the name "V000.oxt" and it replaces any other foreground image that is
currently being displayed.

Having selected manual from the boot-up menu, use the arrow keys W X to
display the emergency to air option and select it by pressing the enter key.

Having selected emergency to air, confirm the intention by pressing the X
arrow key to select Yes then pressing the enter key. This action will fade
down any images that are currently on air before fading up the emergency
image.

Once in the Emergency to Air mode, Imagestore may be reset to its original
state by pressing the escape key as prompted.

As an alternative to using the front panel, the emergency image may be
brought to air using an external button. This is achiev ed by allocating the
emergency to air command to one of Imagestore's GPI inputs. The procedure
for allocating GPI commands is described in the installation and integration
section of this guide.

Live Input

This option is used to load images or patterns (shown in real time on the SDI
Fill and SDI Key inputs) and take them directly to the preview store. This

option is particularly useful for keying external video signals, such as moving
images from a character generator.

With the live input prompt is displayed, press the enter key to load the image
into the preview store.

To cancel a live input condition, load a lib rary image in to the preview store
and the loading action resets the condition.

Loading from FDD

Imagestore requires the 3½" floppy disks to be DOS-formatted (1.44MB) and
the files to be in a format shown in the following table. In each case the
image file extension must match the image format.

When the load from FDD prompt displayed, and a disk is in the drive, press
the enter key to load the file.

As the disk is read, each file on the disk is examined in turn and each image
file found is copied into the image library and loaded onto the prev iew
output. The display will acknowledge a successful or failed load.

The last image loaded from the FDD will remain in the preview store. This
allows a single image file to be easily imported and then taken immediatel y
to air.

The filenames of the original file forms are used to form the file name within
the image library so that FRED.JPG will be saved in Imagestore's library as
FRED.OXT.

Image File Types

File Type Description

TARGA (*.TGA)

8-bit (Greyscale), 24-bit (RGB) and 32-bit (RGB + Key)

'Lossy' compressed images. This format does not support key
information.

Images On More Than One Disk

Various techniques are available to deal with large images and animations
that cannot normally be placed on a single floppy disk.

The Media Conversion Software (MCS) image, animation and clock build ing
tools supplied with Imagestore can all generate disk sets, where a single large
file is split over multiple floppies (called disk spanning)'. When this
technique is used, the MCS tools also apply loss-less compression to the file
to reduce the number of disks required.

To load an image or animation held on multiple floppies put the first disk in
the drive, select the load from FDD option and press enter. Imagestore will
prompt you for the each subsequent disk as it is required.

The floppies can be presented in any order. Imagestore will automatically
combine and decompress the resulting file. Each component file of a multi­disk set has the special name SPANFILE.OXM.

Special File Types

Any file named KEY.TGA is given special treatment as it is taken to be the
key image for the most recently loaded file. This process allows 'fill' and 'key'
Targa files to be combined internally to give the equivalent of a 32-bit

RGB+Key Targa file, by loading two files called, for example
MYPICTURE.TGA and KEY.TGA.

Any file called IMAG.KEY is also treated specially as a key image in .OXT
format. When an image saved by Imagestore cannot fit on a single disk, two
disks are written. The first disk holds a file called IMAG.OXT and the second
disk holds IMAG.KEY.

Library Images

From the Load Image menu use the arrow keys W X to step through the
library images until the name of the image of interest is shown in line two of
the display. The files are shown in alphabetic order and the right and left
arrow keys W X move the filename forward and back respectively. Pressing
the enter key will cause the displayed file to load from the library.

Image Load Mode

This option defines how an image is loaded into the preview store.
Select set-up/image load mode from the boot-up menu then press enter.
Using the left and right arrow keys W X select one of the following options,
pressing the enter key to accept the choice

Wipe Load

As the image/animation is loaded into the preview store it is also disp layed
via the preview output. Larger files may be displayed gradually until th e
image is complete. Animations will be displayed frame by frame until the
entire sequence is loaded.

Clean Load

Clean load removes the existing image from the preview store before loading
the new file. The image/animation will NOT be displayed until it is fully
loaded.

Cut Load

Cut load is similar to clean load but the existing image remains active until
the new file is loaded. A cut transition then replaces the new image for the
old one.

Saving Images

The "Save Image" feature enables the user to save the image currently in the
preview key and fill stores, to the image library, or to floppy disks in the 3½"
disk drive. "Live" images cannot be saved.

Select manual/operate/preview/save image from the boot up menu to locate
this feature.

Images may be saved as Full Image or Cropped. When the image editor has
been used to create a mask for an image, the full image may be saved
together with its mask allowing the option for the mask to be subsequently
enabled, disabled or modifi ed. Where Cropped is selected only the image
within the masking area will be saved thus creating a smaller file but
permanently restricting the image to the boundaries of the mask.

The resultant prompts from the Full Image and Cropped options are identical.
In each case a choice is offered between the floppy disk drive (FDD) and a
numbered location within the image library.

When a save is to be made to the image library, the arrow keys W X are used
to increment and decrement the image number for the save. Where a filename
is already in use an asterisk will appear following the displayed name.

Imagestore User Manual Front Panel Operation

Miranda Technologies Ltd Page 53

If an image is being saved to floppy disk, two disks may be required. If the
image is large, one disk is used to save the Fill store and, if insufficient sp ace
remains on the disk, a second disk is used to save the Key.

Animations and clocks cannot currently be saved to floppy disk. Images are

To grab another image, press the enter key and Imagestore will return to the
preview image state. Repeat grabs can now be made until the required image
is obtained. Once the desired image has been grabbed, the user may exit the
Grab Image mode by pressing the escape key. The grabbed image will
remain held in the preview store.

Editing Images

The image editor enables the user to adjust a number of parameters, all of
which affect the visual appearance of an image.

Once changed, the image ma y be used immediately, or saved for later use.
The following four groups of parameter may be changed:

♦ Clip, Gain and Transparency
♦ Set Position
♦ Masking
♦ Key Parameters

Select manual/operate/preview/image editor from the boot-up menu to locate
the feature.

Imagestore User Manual Front Panel Operation

Miranda Technologies Ltd Page 55

Adjusting Clip, Gain and Transparency

If external faders are being employed for control of clip, gain and
transparency, Imagestore will not offer front panel level setting and will
instruct the user to use the faders. Enabling and disabling external faders is
described in the configuration and set-up section of this manual.

When the clip, gain and tra nsparency option is applied, the user is first
offered an opportunity to adjust the current clip level. The minimum and
maximum levels are shown to the left- and right-hand sides of line two of the
display, with the currently selected level shown in the middle. The right and
left arrow keys W X are used to increase and decrease the setting
respectively.

The setting is applied by pressing the enter key. Once set, the display moves
on to the next parameter Adjust Gain. The adjustment is made in exactly the
same way as for Clip.

Once Gain is set the display moves on to the final adjustment (Adjust
Transparency), which is set in the same way as Clip and Gain.

Clip Level

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 Level

The gain level amplifies the key signal, forcing grey levels towards, and up
to, white level. 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.

Front Panel Operation Imagestore User Manual

Page 56 Miranda Technologies Ltd

Transparency Level

The transparency level controls the amount of background video, across the
whole picture that will 'seep' through the keyed image. This function is
achieved by attenuating th e key signal.

Set Position

The Set Position sub menu offers a choice between horizontal and vertical.
Use the arrow keys W X to select between options as indicated by the
brackets enclosing that option. Press the enter key to apply the selection.

Images may be repositioned horizontally (left and right) and vertically (up
and down) in increments of two pixels. The settings, accessed through the set
position sub-menu, define the relative position between the top left corner of
the visible background and the top left corner of the image.

For a horizontal adjustment, the setting is the number of pixels that the image
is to the right of the top left visible corner of the screen. Negative values are
displayed if the image is moved to the left of that top corner reference where
part of the image would be outside of the visible screen area.

For a vertical adjustment, the setting is the number of pixels that the image is
below the top left visible corner of the screen. Negative values are displayed
if the image is moved above the top corner reference where part of the image
would be outside of the visible screen area.

Masking Images

Images may be masked by restricting the margins and confining an image to
less than full screen. Before any image can be masked the feature must be
turned to enabled. An option within the Set Masking sub menu provides the
enable/disable switching.

Imagestore User Manual Front Panel Operation

Miranda Technologies Ltd Page 57

Images may be masked from the left, right, top or bottom. In each case the
arrow keys W X are used to control the masking.

The minimum a nd maximum levels are shown to the left and right sides of
line two, with the currently selected level shown in the middle. The right an d
left arrow keys W X are used to increase and decrease the setting
respectively and the enter key applies the setting.

Key Parameters

The following three key signal parameters can be set:

♦ Sense (this allows the key signal to be used either normally or inverted)
♦ Source (selects between using no keying, a separately stored key signal,

or an internal key signal derived from the stored picture image)

♦ Type (selects between full or linear keying modes)

For Type, the mode Full Key sums the background (with the key signal
removed) to the foreground. The foreground is only passed where the key
signal is present. This mode is used with self-luma keys. With Linear Key the
mode sums the background (with the key signal removed) to the foreground.
The foreground remains unaf fected by the key .

When the Key Parameters option is selected, the parameters are displayed for
selection as shown below. Use the arrow keys W X to move the brackets to
enclose the parameter to be changed and press the enter key to view the
appropriate sub-menu.

Front Panel Operation Imagestore User Manual

Page 58 Miranda Technologies Ltd

When sense has been selected, the arrow k eys W X are used to choose
between normal and invert. Pressing the enter key applies the selection.

When source has been selected, the arrow keys W X are used to choose
between separate, self and none. Pressing the enter key applies the selection.

When type has been selected, the arrow keys W X are used to choose
between full and linear. Pressing the enter key applies the selection.

Sense

When the sense option is set to normal, a black-level key signal 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 leve ls will prod uce a
pro-rata transparency effect.

Setting the sense option to 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.

Source

When the source option is set to separate, the key data is derived from the
luminance content of the separate "Key" image. When the source option is
set to self, the key data is derived from the luminance content of the "Fill"
signal itself. 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

With Full Key the foreground image is passed only where the key signal is
present. Alternatively, with Linear Key the background and foreground are
summed and the foreground is unaffected by the key.

Cascade Mode Operations (IS2 Only)

Cascade mode operates with the two keyers arranged in series to allow two
images to be keyed simultaneously, but independently, over the background
video. This mode provides a more restricted preview capability, whilst still
providing the some ability to view an image prior to transmission.

The two keyers are identified as the "midground" (MG) keyer and the
"foreground" (FG) keyer. Both layers operate identically, but the "image
editor" feature cannot be used whilst the MG layer is "on-air". If the MG
layer is in use when a user requires the "image editor" feature, the MG layer
would have to be taken "off-air" first.

To change between Swap Preview or Cascade mode select
Set-up/system/Swap-PVW / Cascade.

Press the enter key then use the arrow key W X to select the new mode. Once
selected press enter key.

Cut Up/Down and Fade UP/Down

The cut up/down and fade up/down features affect the MG or FG image that
is present at the programme output. "cut up" and "fade up" take the MG or
FG image "on-air" over a background using a cut or fade transition. "cut
down" and "fade down" take the MG or FG image "off-air" from a
background using a cut or fade transition.

To find the cut up/down and fade up/down features from the "boot-up" menu,
select manual/operate and then choose either midground or foreground from
the Cascade Operate menu. Use the arrow keys W X to locate the cut-
up/down and fade up/down features.

Press the enter key to action a cut (fade) up, or a cut (fade) down. When the
operation takes place the arrow symbol will change from ↑ (cut fade up) to ↓

(cut fade down). No other changes can be detected on the VFD display,
which remains showing the same menu selection for further cut (fade)
up/down operati ons.

Switching Fade to Black On and Off

The FTB on/off feature causes the appropriate keying layer output on-air to
fade to full-screen black. When the output is already faded to black, selection
causes the same layer output on-air to fade from a full-screen black image to
the previously displayed image. The replacement rate is determined by the
setting under transition rates.

Select manual/operate/midground or foreground/FTB on/off from the boot-
up menu to locate the feature.

Front Panel Operation Imagestore User Manual

Page 64 Miranda Technologies Ltd

Press the enter key to action a FTB on/off. When FTB is on the B symbol
will appear next to the arrow (↑ or ↓). When FTB is off no B symbol is

displayed. During the FTB transition the intermediate state symbol – appears
next to the arrow acknowledging FTB is taking place. No other changes can
be detected on the VFD display, which remains showing the same menu for
further FTB on/off operations.

Turning the foreground "fade to black" (FTB) to ON will force the
programme output of the Imagestore to black. With the midground FTB ON,
any foreground image that is currently "on-air" will still be seen over the
black output of the midground keyer.

Loading Images

The load image feature is used to load images from following the floppy
disk, the image library, or "live" from the fill and key input ports.

The arrow keys W X are used to select the source and identity of the file for
loading.

Once loaded the image may be taken on air using the cut-up or fade-up
operations.

Select "manual/operate/midground or foreground/load image from the boot-
up menu to locate the feature.

Imagestore User Manual Front Panel Operation

Miranda Technologies Ltd Page 65

Press the enter key to view the load image menu. When the load image menu
is displayed, use the left and right arrow keys W X to determine the source of
the image to be loaded. The three options available are live input, load from
FDD and filename.

Live Input

This option is used to load images or patterns being presented, in real time,
on the "SDI Fill" and "SDI Key" inputs. The option is particularly useful for
keying external video signals, such as moving images from a character
generator.

If live input is selected for either the MG or FG stores, the grab facility will
be suspended from use (this applies even if the image is not on air). To regain
the "grab" facility, a new image must be loaded into the channel that has live
image selected.

Although the live input function is normally independent of the Background
SDI signal, it should be noted that, if the Imagestore is using the SDI digital
signal as a clocking source, that signal must be present.

Press the enter key and the Imagestore will begin to load the image. If no
signal is present at the Fill input, the operation will terminate.

Load from FDD

Imagestore requires the 3½" floppy disks used to be DOS-formatted
(1.44MB) and that the files be in a format shown in the following table. In
each case the image file extension must match the image format.

With the load fro m FDD prompt displayed, and with a disk in the drive, press
the enter key to load the file.

Full details of FDD image loading are found under Swap-Preview mode.

Front Panel Operation Imagestore User Manual

Page 66 Miranda Technologies Ltd

The filenames of the original file forms are used to form the file name within
the image library so that "FRED.JPG" will be saved in Imagestore's library as
"FRED.OXT".

Images by name

From the Load Image menu use the arrow keys W X to step through the
HDD library files until the name of the image of interest is shown in line two
of the display. The files are shown in alphabetic order and the right and left
arrow keys W X move the filename forward and back respectively. Pressing
the enter key will cause the displayed file to load from the library.

Image Load Mode

This option defines how an image is loaded into the midground or foreground
store. Select set-up/image load mode from the boot-up menu then press enter.
Using the left and right arrow keys W X select one of the following options,
pressing the enter key to accept the choice

Wipe Load

As the image/animation is loaded into the midground or foreground store it is
also displayed via the appropriate output. Larger files may be displayed
gradually until the image is complete.

Note: Animations loaded this way will be displayed frame by frame until

the entire sequence is loaded.

Clean Load

Clean load removes the existing image from the midground or foreground
store before loading the new file. The image/animation will NOT be
displayed until it is fully loaded.

Cut Load

Cut load is similar to clean load but the existing image remains active until
the new file is loaded. A cut transition then replaces the new image for the
old one.

Controls

The RCP’s front panel comprises a backlit LCD display, dedicated push­button switches with legends, menu driven soft-keys and potentiometers.

The RCP also includes the following option buttons on the top-level menu
which you use to select the sub-system you want to control (note that the list
of options available to you will depend on which options have been fitted to
your version of Imagestore):

♦ Mixer (opt i o nal feature)
♦ Logos (standard feature included with all Imagetsore systems)
♦ Squeezy (optional feature)
♦ Audio (optional feature)

(see Soft Keys below for details about how to choose these options)
During the power-up self-test sequence the integral lamp within each push-

button switch will illuminate in turn. The following paragraphs describe the
use of the controls for new users.

Display

The LCD display provides interactive access to the control menus of the

shortly after power is first supplied and can be reached at any ti me by
repeatedly pressing the "ESC" key.

The brightness and contrast of the display may be adjusted to suit the user by
pressing the "Setup" key followed by the left-hand soft key (identified on­screen as RCP). These actions will bring up the "Set LCD & Keys" menu and
the left and right rotary potentiometers may be used to make adjustments.
Lamp brightness can also be adjusted to suit ambient conditions.

Push Button Switches

The RCP has thirty dedicated pushbuttons of which eleven comprise an
alphanumeric keypad ("0" to "9YZ" plus ENTER). The following paragraphs
describe the use of each button in turn.

Imagestore User Manual Oxtel RCP Operation

Miranda Technologies Ltd Page 73

ESC Key

The ESC key is used to return to the basic display. When the basic display is
being presented the key is not illuminated. Once a control menu is selected
the button becomes illuminated indicating that th e button is now providing a
function. To return to the basic display press the button repeatedly until it is
extinguished.

Menu Keys

The six keys to the right of the ESC key are the menu keys. Keys that are
illuminated are available for use. Any key that is not illuminated is
unavailable either because the feature is not currently appropriate or the unit
connected does not support that feature.

Pressing any available (illuminated) menu key results in the appearance of an
operational display. Use of these features is described in the section relating
to the product connected to the remote control panel.

Load

The LOAD key provides access to the image loading, grabbing and "live"
loading options.

Save

The SAVE key provides access to the image saving and image erasure
options.

Edit

The EDIT key provides access to any image editing options that are available
on the controlled equipment.

Play List

The PLAY LIST key provides access to the options for creating, loading,
unloading and editing a Playlist.

Oxtel RCP Operation Imagestore User Manual

Page 74 Miranda Technologies Ltd

Setup

The SETUP key provides access to provision for setting the LCD
parameters, accessing the polyphoto display, setting fade transition rates and
for configuring the sampling point of the controlled equipment preview
output.

Next Del

The NEXT DEL key is used to delete characters of names that have been
entered on the alpha numeric keypad. For e x ample, if a file were to be named
"MIRANDA" and was incorrectly entered as "MIRANAD", the NEXT DEL
key could be used to delete the final "D" and "A" allowing a correction to be
made.

Alphanumeric Keypad

The alphanumeric keypad comprises keys "0" to "9YZ_" and the ENTER
key. These keys are not normally illuminated and become illu minated only
when a procedure is selected which might require their use.

When using the keypad to enter a file name, use the set-up RCP feature to
select the buttons for "alpha" or "numeric" mode. Where "alpha" is selected,
press the key once for the first character, twice for the second alphabetic
character and so on.

When the appropriate character is displayed, pressing a different
alphanumeric key will automatically move the entry cursor. Where the same
key is to be re-used, move the cursor manually using the left-hand rotary
control.

If a keying error is made, pressing the "ESC" key will cancel the complete
entry and "NEXT DEL" key will delete the last character entered. When all
the appropriate characters have been entered pressing the ENTER key will
apply the entry.

Fade to Black

The operation of the "FADE TO BLACK" key differs from the other keys in
that its illumination is not intended as an indication of its availability. When
the "FADE TO BLACK" key is illuminated it indicates that a Fade to Black
status is in effect and that the output is currently faded to black. Should

Imagestore User Manual Oxtel RCP Operation

Miranda Technologies Ltd Page 75

pressing the "FADE TO BLACK" key fail to result in the button illuminating
or the programme output fading, wait to see if a long fade rate has been set
before concluding that this feature has bee n disabl ed.

Previous (Prev)

When a play-list is not loaded, and an image is being monitored at the PVW
output, pressing "PREV" (previous) will load the preview keyer with the
preceding image from the image library. In play-list mode the image loaded
will be the preceding image in the play-list.

In polyphoto mode the "PREV" key will move the cursor (flashing yellow
dot) to the previous thumbnail image.

Next

When a play-list is not loaded, and an image is being monitored at the PVW
output, pressing "NEXT" will load the preview keyer with the following
image from the image library. In play-list mode the image loaded will be the
following image in the play-list.

In polyphoto mode the "NEXT" key will move the cursor (flashing yellow
dot) to the following thumbnail image.

Take and Swap

The “TAKE” light is lit when the image selected on the programme output is
“on-air”. The light is out when the programme image is cut or faded down.

The "TAKE" key can be used to take logos/images to and from air over the
background signal or to exchange the contents of the preview and programme
keyers. The effect of this key depends on the status of the "SWAP" key.
Pressing the "SWAP" key selects and deselects the swap condition and
determines the action of the "TAKE" button and the illumination of the swap
legend is toggled.

With the swap legend illuminated the "TAKE" button exchanges the
logo/image on air with the preview logo/image using the selected cut or fade
effect. With the swap legend not illuminated successively pressing the
"TAKE" button simply takes the programme logo/image on and off air.

Oxtel RCP Operation Imagestore User Manual

Page 76 Miranda Technologies Ltd

Cut/Fade

The "CUT/FADE" key is used to toggle between the two options controlling
the type of transition to and from air of the programme keyer. The current
selection is indicated by the illumination of the legend above the button. This
setting only affects keyer fade transitions and does not affect the programme
"fade to black" transition or the keyer "cut" transition.

Rate

The "RATE" key is used to switch between the speed options for keyer fade
transitions. The current selection is indicated by the illumination of the
legend above the button and only the op tion currently selected is illuminated.
Rates are set using the "Set-Up" feature.

FG Keyer and MG Keyer

These two keys are only effective when the RCP is connected to an
Imagestore that is operating in the "Cascade" mode. FG is an abbreviation of
foreground and MG is an abbreviation of midground. The keys are used to
determine the keyer affected by current operations.

Channel Set

The "CHAN'L SET" key is only effective when the RCP is used via an
Miranda Technologies Ltd Intelligent Panel Router. Pressing the "CHAN'L
SET" key will provide access to the "Channel Set" menu.

Soft-Keys

The remote control panel features four soft-keys which are positioned from
left to right under the LCD. These keys have no dedicated purpose and are
allocated by the different menus as is appropriate for a particular purpose.
When a purpose is to be allocated to any soft key a legend will appear on the
LCD directly above the key indicating its temporary purpose.

Rotary Controls

The remote control panel features three rotary controls which are positioned
from left to right above the LCD. These "pots" have no dedicated purpose
and are allocated by the different menus as is appropriate for a particular

Imagestore User Manual Oxtel RCP Operation

Miranda Technologies Ltd Page 77

purpose. When a purpose is to be allocated to any "pot" a legend will appear
on the LCD directly below the "pot" indicating its current purpose.

Swap/Preview Mode Operations

The RCP can be used in either of the two operational modes to co ntrol image
loading, image editing, image previewing, image saving and image
transmission. The features and facilities available differ significantly
dependent on the operational mode. This user guide describes both modes
separately and some duplication may occur.

In all circumstances pressing the ESC button repeatedly until it is no longer
illuminated returns the controller to its start up display.

Transmission Control

The group of buttons in the bottom, right-hand corner of the controller is used
to take images on and off air and to exchange images between the program
and preview keyers. The use of these buttons does not involve any prompts
on the controller LCD.

Note The SWAP button is used to determine the action of the TAKE

button and pressing it will cause the legend above the SWAP button
to either illuminate or extinguish.

Program Fade to Black

Pressing the "Fade to Black" button will cause the programme output to fade
to black over the number of frames set for that transition.

When the output has been faded to black the button becomes illuminated.
Pressing the button again will cause the normal program output to reappear
over the same number of frames and the button light will go out.

The FTB option may be disabled where appropriate and the Miranda
Technologies Ltd helpdesk will provide details on request.

Program Image "On Air/Off Air"

When taking a foreground image "on-air" or off-air", the condition of the
SWAP button is crucial. Ensure that the legend marked SWAP above the
swap button is extinguished. If it is illuminated, press the SWAP button to
extinguish the legend. With the SWAP legend extinguished, pressing the
TAKE button takes the foreground image "on air" over the background.
When the foreground image is "on air", pressing the TAKE button will
remove it "off air".

Exchanging Program and Preview Images

When exchanging the cont ents the Program and Preview Images stores, the
condition of the SWAP button is crucial. Ensure that the legend marked
SWAP above the swap button is illuminated. If it is not illuminated, press the
SWAP button to illuminate the legend. With the SWAP legend illuminated,
pressing the TAKE button exchanges the Program and Preview images.

Selecting Transition Speed

Each time the "Rate" button is pressed the rate selection will step through its
options. The currently selected option is indicated by which of the settings
("Slow", "Med" and "Fast") is illuminated. This determines the rate at which
the images will come to air when selected. The actual transition rate values
may be preset (in fields) using the "Set-Up" menu.

Cut or Fade Selection

When the "Cut/Fade" button is pressed, the type of keyer transition toggles
between cut and fade. The current setting is shown illuminated above the

Loading Images

Pressing the 'LOAD' button brings the load image display to screen. "Load"
provides access to three types of image loading. These allow loading of
images, animations and clocks from the Imagestore library, capturing and
storing frames of video input (Grab), or allowing live video from the Fill and
Key inputs to be keyed over the background video (Live).

Loading from the Image Library

Images can be loaded by numeric entry, filename, and title. The 2

nd

from left
soft-key toggles between "File" and "Title" to determine which of those
methods is to be used for searching.

Images using numeric filenames (example V123.OXT) may be loaded by
simply entering the 3-digit value (example 123) at the keypad and pressing
ENTER.

The rotary control associated with "Letter" is a coarse control quickly
scrolling through the library images displaying the first file, or title, starting
with each alphanumeric character. Once the starting character has been
located the rotary control under "File" may be used as a fine control to step
forwards or backwards through each file or title from that point.

The rotary control associated with "Cursor" may be used to move the cursor
through a file name or title. The keypad may be used to amend any character.

Once the required image is indicated on the di spl ay , pressing the ENTER key
will cause it to load into the preview store.

Oxtel RCP Operation Imagestore User Manual

Page 80 Miranda Technologies Ltd

Loading a Live Image

To load the image at the Fill and Key video inputs, press the left-hand soft­key, identified on the display as "Live". The "Live" image loads into the
preview channel and may be cut swapped, fade swapped, cut up and down,
faded up and down, as with any o th e r image.

Cascade Mode Operations

Cascade mode offers two-layer keying (midground and foreground). For
example, both a logo and a caption may be simultaneously, but independently
inserted over a background signal. Image editing and image saving are not
available in Cascade mode.

To control the foreground layer, press the "FG KEYER" button. To control
the midground layer, press the "MG KEYER" button.

Transmission Controls

The buttons grouped in the bottom, right-hand corner of the controller are
used to change the program output and to take images "on air" and "off air".
The use of these controls does not involve prompts or displays on the
controller LCD.

Program Fade to Black

Pressing the "Fade to Black" button causes the appropriate keying layer
output on-air to fade to full-screen black. When the output is already faded to
black, selection causes the same layer output on-air to fade from a full-screen
black image to the previously displayed image. The replacement rate is
determined by the "Rate" setting.

Turning the foreground "fade to black" (FTB) to "ON" will force the
programme output of the Imagestore to black. With the midground FTB
"ON", any foreground image that is currently "on-air" will still b e seen over
the black output of the midground keyer.

Foreground/Midground Images "On Air"

To take either a midground or foregroun d image "on air", first press the
appropriate FG or MG button which will illuminate accordingly. If the TAKE
button is illuminated the image for that layer is already on air and vice versa.
Pressing the TAKE button will either take the image on-air (button
illuminated) or off air (button extinguished).

Miranda Technologies Ltd Page 89

Selecting Transition Speed

Each time the "Rate" button is pressed the rate selection will step through its
options. The currently selected option is indicated by which of the settings
("Slow", "Med" and "Fast") is illuminated. This determines the rate at which
the keyer logo/images will come to air when selected.

Cut/Fade Selection

When the "Cut/Fade" button is pressed the type of keyer transition toggles
between cut and fade. The current setting is shown illuminated above the
button. This determines the effect that is used to bring images to air.

Loading Images to Foreground and Midground

Once the "MG KEYER" or "FG KEYER" button has been selected the
procedure for loading images is identical and the following description is
equally valid for both.

Press the appropriate keyer button ("FG KEY E R" for foreground or "MG
KEYER" for midground). Press the "LOAD" button to display the "Load
Image" menu that provides access to two types of image loading; library
image or "live" from the "Fill" and "Key" ports.

Load from the Image Library

In order to load an image from the Imagestore library the image to be loaded
must be identified. Locating an image for loading can be achieved using the

either the file name or the image title. The 2nd from left soft key toggles
between "File" and "Title" to determine which is to be used for searching.

The rotary control associated with "Letter" is a coarse control quickly
scrolling through the library images displaying the first file, or title, starting
with each alphanumeric character. Once the starting character has been
located the rotary control under "File" may be used as a fine control to step
forwards or backwards through each file or title from that point. The rotary
control associated with "Cursor" may be used to move the cursor through a
file name or title and the keypad may be used to amend any character.

Once the required image is indicated on the di spl ay , pressing the ENTER key
will cause it to load into the preview keyer.

Loading a Live Image

To load the layer image at the Fill and Key video inputs directly to the
programme output, press the left-hand soft key, identified on the display as
"Live". The video input will then be passed directly to the either the FG or
MG keyer and appear on the PGM output. The display will indicate "Live
Loaded".

To cancel or override the "live load" condition, select an image from the
Imagestore library and load it. The action of loading a new image to the
keyer will cancel the "live" condition.

Saving Images

The procedure for saving images from either the foreground or midground
stores in Cascade mode is identical to that for Swap-PVW mode and
reference should be made to that description.

Editing Images

Images can only be edited in Cascade mode when the midground keyer is not
"on-air". Ensure that there will be no requirement for the midground image to
be taken "on-air" during an editing session.

When using the Cascade mode editing features refer to the "editing images"
section of RCP Swap-PVW Mode given in earlier paragraphs of this guide.
