ISM 482 Integrated Scaling Matrix Switcher • Introduction 3

Features

• Inputs

• Video inputs — The ISM switches among eight fully-configurable RGB, HDTV

component video, component video, S-video, and composite video inputs on five

BNC connectors per input.

• Audio inputs — The ISM switches among eight balanced or unbalanced stereo or

mono audio inputs on 5-pole captive screw connectors.

• Outputs

• Standard video outputs — The ISM outputs individually scaled video signals as

RGBHV or RGBS. Two sets of BNC connectors and two 15-pin HD connectors are

provided. One set of BNC connectors and one 15-pin HD connector display the

output 1 image, and the other set of BNC connectors and 15-pin HD connector

display the output 2 image.

• Optional DVI video output — If you install the optional DVI output card, a single

buffered DVI-D signal can be output as an additional output 1 image.

NOTE: For output resolutions with less than 1024 pixels horizontally, the

optional DVI output’s true horizontal resolution is limited to 1024 pixels. For

the 1365 x 1024, 1080p, and 1080i output resolutions, the optional DVI

output’s true horizontal resolution is limited to 1280 pixels. The DVI card

outputs all other selected resolutions normally (see the table on page 20).

• Audio outputs — The ISM outputs the selected unamplified, line level, balanced or

unbalanced stereo or mono audio on 5-pole captive screw connectors.

• Accu-RATE Frame Lock™ (AFL™) — A patented technology exclusive to Extron that

solves frame rate conversion issues experienced by video scalers. When video input

and output refresh rates differ, occasionally the two rates cross over each other. The

result is a glitch or image freeze on the display. AFL solves this problem by locking the

output frame rate to the frame rate of input 1.

• Dynamic Motion Interpolation™ (DMI™) — This video processing technique is an

advanced motion prediction and compensation method that treats motion content and

still content with different algorithms to yield high fidelity images.

• 3:2 pulldown detection for NTSC video sources and 2:2 film detection for PAL

— These advanced, patent pending, 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 deinterlacing 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 process, 2:2 film detection, is used for PAL film-source video.

• Audio follow and breakaway — Audio switching can follow its corresponding video

input signal or it can be broken away from the video input. Audio breakaway switching

can be done via front panel control or under RS-232 or Ethernet remote control.

• Audio gain/attenuation — Users can set the input level of audio gain or attenuation

(-24 dB to +9 dB) via the RS-232 port, Ethernet link, or from the front panel. Individual

input audio levels can be adjusted so there is no noticeable volume difference between

sources.
