Integration Scaling Matrix Switcher • Introduction 1-4
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.
