The VS870 is a standalone solution for video format conversion and processing. It accepts a number of video inputs and displays these in a full screen or windowed / picture-in-picture format on its video outputs.
A powerful FPGA is used to provide flexible buffering, scaling and processing of multiple simultaneous video streams:
each source may be displayed full screen or within a programmable window; the Z-order of windows is programmable to control the results of overlapping windows;
overlay of one video source over another is supported, with transparency controlled separately within multiple programmable regions and/or via chroma keying;
a character generator provides support for a text overlay with user defined characters as well as programmable foreground and background colours and/or transparency.
Additional capabilities such as simple graphics may be provided by firmware customisations.
