VxPoint Video Crosspoint Switch
VxPoint is a single slot, semi-ruggedized 6U VME Video Crosspoint Switch card which will accept up to 8 standard video signals and will route these to any of 32 outputs with virtually no loss in image quality. A wide range of video formats can be accommodated including composite NTSC or PAL signals and high resolution RGB video. The card incorporates a microprocessor for controlling the on-board circuits and is able to function as a communications controller via its four serial ports. An encoder is also provided to convert between RGB video and PAL or NTSC encoded composite video.
The on-board firmware interprets commands received via the serial lines or via the shared memory interface on the VME bus. It also communicates with other cards via the remaining serial lines. Comprehensive built-in test routines verify the correct operation of the on-board circuits at power-on and when initiated by the host.
