Abstract
A method and apparatus that combines video streams to reduce interconnection between video processors and rendering devices is presented. Multiple video streams are multiplexed at particular phases of a clock signal so that, at the rendering device, the desired video stream is selected by selecting the appropriate phased clock signal. In a preferred embodiment, the combined signal is compatible with conventional single-port rendering devices, such as displays, video recorders, and video encoders. Also presented is a means for selecting among multiple video streams that minimizes the number of interconnections that are switched.
