Abstract:
A video multiplexer apparatus comprising:a plurality of video input connectors that supply video signals, where some of the video signals are discrete video signals that have multiple discrete components, and some of the signals are combined video signals that have multiple components combined into a single signal;a plurality of programmable signal connectors, having video inputs and video outputs, said video inputs connected to receive video signals from said video input connectors, said programmable signal connectors operable to selectively multiplex the video signals received from said the video input connectors, wherein the video input convectors are coupled to said video inputs such that one programmable signal connector receives discrete video signal components of one type from different ones of said video inputs, and another one of said programmable signal connectors receives discrete video signal components of another type from different ones of said video inputs;a plurality of video output connectors, coupled to the video outputs of the plurality of programmable signal connectors, for receiving output video signals from the plurality of programmable signal connectors for processing through a first video stream and a second video stream;wherein at least one of said combined video signals is coupled from a video output of a first programmable signal connector to a video input of a second programmable signal connector, and then from a video output of the second programmable signal connector to a digital comb filter to separate the components of said composite video signal into respective signal streams.
