About the Switcher
The ISM 482 is an eight-input, two-independently-scaled-output, video and stereo
or mono audio matrix switcher. Figure 1-1 shows a typical ISM 482 application.
The switchers accept high resolution RGB video, YUV (component) video,
S-video (Y/C), and composite video inputs; scale the inputs; and output RGBHV or
RGBS video and stereo audio. Triple-Action Switching™ (RGB delay) blanks the
screen during the switch to prevent distracting video glitches. The switcher’s two
independent scalers permit differing video formats on each input to be displayed
in different resolutions on different projectors.
Each video input is individually configurable to allow for different video formats.
The ISM allows analog RGBHV, RGBS, RGsB, and RGBcvS video, component
video, S-video, and composite video signals to be displayed on a device with a
fixed resolution and aspect ratio, such as a liquid crystal display (LCD) projector,
digital light processor (DLP) projector, or plasma display.
The ISM provides two separate outputs. The selected input can be switched to
either or both outputs. With an optional DVI output card, the ISM converts the
scaled image to DVI as an additional set of output 1 signals.
The switcher inputs all valid video signal formats on eight sets of five BNC
connectors. The ISM 482 scales the input up or down to a wide variety of output
resolutions and rates. The switcher outputs the scaled video, as RGBHV or RGBS,
on two sets of output connectors, consisting of five BNCs and a 15-pin HD
connector. These connectors share identical outputs.
Several of the output resolutions and rates include Extron’s Accu-RATE Frame
Lock™ (AFL™), a proprietary technology that locks the output frame rate to the
input rate, solving the image tearing problem that can result from different input
and output rates. The switcher features HDTV 576p, 720p, 1080p, and 1080i outputs.
