1-5 ISM 824 Integration Scaling Multiswitcher • Introduction
Features
Inputs —
Video inputs — The ISM switches among eight configurable 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 boards — With optional scaler, scan converter, dual or single
wideband output boards 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 board type installed:
• ISM RGB, ISM DVI, or ISM HDSDI (Universal Video and RGB Scalers
with BNC, DVI, or HDSDI output connectors) — Scales any low or high
resolution input signal to a high resolution signal up to 1920 x 1200, 720p,
1080i, or 1080p.
• ISM VS (Video Scaler) — Scales any low resolution input 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 board.
• ISM 2WB Dual output wideband — This optional board takes any two
input signals and passes them through unprocessed on two 15-pin HD
connectors.
• ISM 1WB Single output wideband — This optional board 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 film. When film 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.
