Imagestore HDTV User Manual Overview
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
HDTV 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 HDTV (Product code IS-HDTV) is part of Miranda Technologies
Ltd's professional broadcast equipment range of products and its primary use
is to insert logos into a HD-SDI digital video signal. The capabilities of this
2U unit include simple logo insertion, still and animated images.
Applications
Imagestore HDTV is typically used to insert a still or animated logo, a
channel identification, a programme schedule, an advertisement, an
emergency image, or a combination of any two of those. Each of these
resources may be brought on-air from the 40-image library (optionally 400 or
1000 image). Alternatively, external 'live' fill and key signals from a
character generator, or a still/animation store, can be directly inserted into the
HD signal.
Concept
Imagestore HDTV is set up for operation where the two keyers are arranged
in series as shown below. This configuration allows two images to be keyed
simultaneously, but independently, over the background video.
A fail-safe mechanical Video Relay Bypass option (VRB-HD-001) is
available that directly connects the background video source to the
programme output in the event of a power supply problem.
Miranda Technologies Ltd Page 19
Overview Imagestore HDTV User Manual
Still (.oxt) and animated (.oxa) 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-002-HD) is designed for this purpose and
is supplied with each Imagestore HDTV.
An Ethernet interface option (NET-HD-001) 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 Media
Distribution System (MDS). The MDS software provides for transfer and
management of still-images and animations. Files may also be transferred
using an FTP program.

Getting Started
Applying Power
Before applying power, ensure that the floppy disk
drive does not contain a disk.
Imagestore HDTV 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. In the event the second PSU option
(PSU-HD-001) in not fitted always connect to the IEC
socket labelled PSU1 first.
Miranda Technologies Ltd Page 21
Overview Imagestore HDTV User Manual
Boot-Up Sequence
Once power is applied Imagestore HDTV will boot automatically and the
complete process takes about 30 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
The entry-level Imagestore HDTV provides storage for up to forty full-screen
images with their associated keys and this can currently be upgraded to 400
or 1000 images. 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) and animation (.oxa) files saved to floppy disks from Miranda
Technologies Ltd's Media Conversion Software - (or other Miranda
Technologies Ltd units) can be loaded in the same way. The Media
Page 22 Miranda Technologies Ltd
Imagestore HDTV User Manual Overview
Conversion software allows large animations and images to be saved across
multiple floppy disks (span files .oxm), using loss-less compression to reduce
the number of disks required.
Miranda Technologies Ltd also provides an image transfer and management
system for Imagestore HDTV. The Media Distribution System (MDS) uses a
local area network to 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.
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 HDTV 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 or 1000) 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 HDTV.
There are two 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 for larger animations, up to full screen, are reduced proportionally
to the area used. Areas are evaluated each frame so bugs may change in size
with no penalty.
Miranda Technologies Ltd Page 23
Overview Imagestore HDTV User Manual
With 256MB of playout memory, a logo of ¹/64 screen size can be animated
for just over 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 package
supplied with Imagestore HDTV.
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.
AB Mixer
The optional integral AB Mixer (MIX-HD-001) video switcher is designed to
be fed by an any of the units input sources or by an external router under
automation control. The mixer provides cut and cross 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
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.
Page 24 Miranda Technologies Ltd
Imagestore HDTV User Manual Overview
Imagestore HDTV is highly suited to automated broadcast environments and
remote control options include RS422/RS232, as well as GPI and analogue
fader inputs.
Mechanical Bypass
In the event of power loss to the Imagestore HDTV, or failure of an internal
power supply, the mechanical video relay bypass option (VRB-HD-001)
routes the serial digital "background signal" directly to the programme
output. This feature is an emergency failsafe and is completely nonsynchronous in operation. During boot-up, the bypass is maintained until
Imagestore HDTV is fully operational.

Imagestore HDTV User Manual Front Panel Operation
Front Panel Operations
This section of the manual explains, on a task-by-task basis, the operation of
an Imagestore HDTV using only the front panel controls. Each task is fully
detailed, making reference to other sections unnecessary.
Controls
All of Imagestore HDTV's operational and configuration features can be
monitored 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 HDTV contains a 3½ floppy disk drive, four
push-button 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 displayed on the VFD. The upper key of the group
is identified on the panel as the escape key and the bottom 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 W and X are used to indicate that other options exist to the left
and right respectively. Using the appropriate arrow key will reveal those
options.
Any options shown in brackets i.e. (AB Mixer) denotes a licensed option
where the appropriate license has not been installed.

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 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 key may be used to
reduce the displayed value and the right key may be used to increase it.
