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.

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 3-10.

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 input frame rate.

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.
