Features

Inputs —

Video inputs — The ISM switches among eight fully-configurable RGB, HDTV component video (ISM 482), 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 —

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.

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 feature helps 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 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 (-24dB to +9dB) via the RS-232 or Ethernet link or from the front panel. Individual input audio levels can be adjusted so there is no noticeable volume difference between sources.

Ethernet port — Supports connection to an Ethernet LAN so that the switcher can be accessed and operated from a computer running a standard Internet browser anywhere in the world.

Quad-standard video decoder — The switcher uses a digital, four-line adaptive comb filter that can decode NTSC 3.58, NTSC 4.43, PAL, and SECAM.
