The multiswitcher accepts up to eight video inputs of various resolutions on five
female BNC connectors per input. Depending on the output card configurations,
the multiswitcher scales, down-converts, or simply passes the video inputs to
output RGB or YUV video. The outputs are made on five female BNC connectors,
or two 15-pin HD connectors (dual wideband card only). Inputs and outputs are
made in the following signal formats:
• RGB (RGBHV, RGBS) video
• YUV-HD (HDTV) video
• Progressive YUV component video
• Interlaced YUV component video
• S-video (Y/C)
• Composite (NTSC, PAL, SECAM) video
Each video input is individually configurable for color, tint, brightness, contrast,
detail, position, size, and zoom via the front panel, RS-232/RS-422, or Ethernet
control. The ISM also allows the various high-resolution and low resolution video
formats to be displayed on a device with a fixed resolution and aspect ratio, such as
a liquid crystal display (LCD) projector, a digital light processor (DLP) projector, a
plasma display, or, optionally, a DVI or HD-SDI device.
Figure 1-1 shows an example of an ISM 824 application.
