Abstract
A system for reducing the bandwidth of a data stream transmitted via a digital multimedia link does not result in the loss of data. The system encodes control signals such that control words are generated each time the status of the control signals change. The system multiplexes payload data and the control words to generate the data stream. If no blanking period of the payload data is present, the data stream comprises payload data. During the blanking period, the data stream comprises the control words. The data stream is transmitted across the digital multimedia link using transmit and receive FIFO memories. The transmitted data stream is then demultiplexed, and the payload data and the control words are separated from each other. The control words are decoded to recover the control signals. The system can transmit payload data conforming to the video formats VGA, SVGA, XGA, SXGA and UXGA.
