A system and method for time division multiplexing multiple lower bandwidth signals into a high bandwidth signals such as a high-definition television signal. The invention provides an integrated transmission, distribution and routing signal format in which low-bandwidth signals are embedded in the active video and vertical blanking areas of a high-bandwidth signal. Data from the source data streams, including timing data, is formatted in packets, each packet comprising a plurality of channels. The packets are inserted into the high-bandwidth signal along with a header word providing a 'data valid bit' or 'status bit' for each of the channels, which identifies valid data words within the packet. The source data streams are accurately reconstituted by de-multiplexing according to header data specifying routing destination, stream ID, stream type, channel usage and stream clock reference for clock recovery at the receiving end.

The present invention relates to a video display processor comprised apparatus for receiving digital input signal components of a signal to be displayed, apparatus for converting the components to a desired format, apparatus for scaling and blending the signals in the desired format, apparatus for outputting the scaled and blended signals for display or further processing, and an arbiter and local timing apparatus for controlling the apparatus substantially independently of a host CPU.

The present invention relates to a method of converting signal components of one of a first input three component color model signal and a second input three component color model signal to either one of the first or second three component color model comprised of matrix multiplying input signal components with an array of predetermined transformation parameters to form a multiplied set, vector adding the multiplied set with a predetermined group of offset vectors, whereby signal components of the output signal are produced.
