ISM 824 Integration Scaling Multiswitcher • Introduction
Features
Inputs —
Video inputs — The ISM switches among eight congurable RGB, HDTV
component video, component video, S-video, and composite video inputs.
Audio inputs — The ISM switches among eight balanced or unbalanced stereo or
mono audio inputs on 5-pole captive screw connectors.
Outputs —
Standard pass through video outputs — The ISM 824 outputs any video signals,
unprocessed, on outputs 1 and 2.
Optional output cards — With optional scaler, scan converter, dual or single
wideband output cards installed in the expansion slots, up to six additional
program video outputs are available. The output signals are scaled,
converted or passed through, based on the card type installed:
• ISM RGB Universal Scaler — Scales any low or high resolution input
signal to a high resolution signal up to 1600 x 1200 or HDTV 1080p.
• ISM VS Video Scaler — Scales any low resolution input output up
to 1400 x 1050 or HDTV 1080p. High resolution inputs pass through
unchanged.
• ISM SC Scan Converter — Converts any high resolution input signal to a
low resolution signal. Genlocking of any converted signal to an external
sync source is available with this output card.
• ISM 2WB Dual output wideband — This optional card takes any two
input signals and passes them through unprocessed on two 15-pin HD
connectors.
• ISM 1WB Single output wideband — This optional card takes any input
signal type and passes it through unprocessed on BNC connectors.
Audio outputs — The ISM outputs the selected unamplified, line level, balanced
or unbalanced stereo or mono audio on 5-pole captive screw connectors.
3:2 pulldown detection for NTSC and 2:2 film detection for PAL video sources —
These advanced film mode processing features help maximize image detail
and sharpness for video sources that originated from lm. When lm is
converted to NTSC video, the film frame rate has to be matched to the video
frame rate in a process called 3:2 pulldown. Jaggies and other image artifacts
can result if conventional de-interlacing techniques are used on film-source
video. The ISM’s advanced film mode processing recognizes signals that
originated from film. The ISM then applies video processing algorithms
that optimize the conversion of video that was made with the 3:2 pulldown
process. This results in richly detailed images with sharply defined lines.
A similar 2:2 pulldown process is used for PAL film-source video.
Switching flexibility — Provides individually buffered, independent matrix
switched outputs with audio follow and audio breakaway for audio models.
• Tie any input to any or all outputs
• Quick multiple tie — Multiple inputs can be switched to multiple outputs
simultaneously. This allows all displays (outputs) to change from source to
source at the same time.
• Audio follow — Audio can be switched with its corresponding video input
via front panel control or under Ethernet or RS-232/RS-422 remote control.
• Audio breakaway — Audio can be broken away from its corresponding
video signal. This feature allows any audio signal to be selected with any
video signal simultaneously to one or all outputs in any combination. Audio
breakaway switching can be done via front panel control or under Ethernet or
RS-232/RS-422 remote control.
