Abstract

A communication system (Fig. 2) including a transmitter (1'), a receiver (2'), and a serial link, in which encoded data (e.g., video, audio, and optionally also other auxiliary data) are transmitted from the transmitter (1') to the receiver (2'). The serial link can but need not be a TMDS or TMDS-like link. In typical embodiments, packets of encoded audio data are transmitted over each of one or more channels (CH0, CH1, CH2) of the link during data islands between burst of encoded video data, a pixel clock is transmitted over the link, and the receiver (2') regenerates a clock for the audio data using time code data in the packets and the pixel clock. Other aspects of the invention are transmitters for transmitting encoded data and a pixel clock over a serial link, receivers for receiving such data and pixel clock and performing audio clock regeneration, and methods for transmitting encoded data and a pixel clock over a serial link and performing clock regeneration using the transmitted data and pixel clock.
