Abstract:
1. Apparatus for communicating multimedia data over a wired communication channel, comprising: a transmitter, operating at a predetermined clock rate, coupled via an interface to the wired communication channel, and further having an encoder for forming data packets having at least a packet sequence number and a packet re-transmit number associated with the data packet; and a receiver, coupled via an interface to the wired communication channel and having a timer and a decoder, wherein the decoder operates at a clock rate that is substantially the same as the clock rate of the encoder in the transmitter but independent therefrom; means for receiving user entered signals to cause a channel selection signal to be transmitted from the receiver to the transmitter via the wired communication channel; means for acknowledging, at each receiver, receipt of a valid received data packet and a correct packet sequence number associated therewith; and means for synchronizing the initiation of playback of the multimedia data in each receiver according to the arrival time of a first received data packet having a zero-valued re-transmit number.
