SYSTEM AND METHODS FOR ALIGNING CAPTURE AND PLAYBACK CLOCKS IN A WIRELESS DIGITAL AUDIO DISTRIBUTION SYSTEM

摘要

A wireless digital audio distribution system includes a transmitter that performs parallel acquisition of audio data from plural audio data channels. The acquired data is stored to a first buffer during intervals defined by a first clock unit. A radio transmitter provides for the packetization of the parallel collected data and the inclusion of a timing marker in a predetermined packet of data transmitted during an interval. A receiver unit delivers audio output data corresponding to one of the audio data channels. The receiver unit includes a radio receiver for receiving packetized data and storing second parallel collected data to said second buffer. A demultiplexer is coupled to the second buffer to select the audio output data corresponding to the selected one of the plural audio data channels, whereby the audio output data is available for the selective reproduction of the chosen audio data channel.
