System and method for generating and processing a stream of video data having multiple data streams

A system For processing a video stream having at least one video signal, said system comprising:

• a computer;
• a video card connected to said computer;
• and a frame processing card connected to said computer, wherein said video card generates a digital video signal by inserting said at least one video signal at an insertion rate into said digital video signal, said video card is caused to delay said at least one video signal into said digital video signal when said frame processing card would not be able to properly process said at least one video signal, said processing card is adapted to update a counter used to determine when to delay inserting said at least one video signal into said digital video sianal, said digital video signal is transmitted from said video card at a transmission rate to said frame processing card through a video output port of said video card, said transmission rate being greater than said insertion rate, an externally-generated video synchronization signal relating to said at least one video signal is provided to said frame processing card and said frame processing card extracts said at least one video signal from said digital video signal utilizing said video synchronization signal to maintain a frame rate for extracting said at least one video signal.

A processing card for processing a video stream having at least one video signal encoded in a digital video signal received from a video card, said processing card adapted to extract said at least one video signal from said digital video signal utilizing an externally-generated video synchronization signal related to said at least one video signal to maintain a frame rate for extracting said at least one video signal, said processing card adapted to signal to said video card to delay inserting said at least one video signal into said digital video signal when said processing card cannot properly process said at least one video signal, and said processing card adapted to update a counter used to determine when to delay inserting said at least one video signal into said digital video signal.

A processing card for processing a video stream having at least one video signal encoded in a digital video signal received from a video card, said digital video signal encoded in a DVI format, said processing card adapted to extract said at least one video signal from said digital video signal utilizing an externally-generated video synchronization signal related to said at least one video signal to maintain a frame rate for extracting said at least one video signal, said processing card adapted to signal to said video card to delay inserting said at least one video signal into said digital video signal when said processing card cannot properly process said at least one video signal, and said processing card adapted to update a counter used to determine when to delay inserting said at least one video signal into said digital video signal.
