Abstract
A multichannel wireless digital audio distribution system provides for the synchronization of the output of audio data by different receiving units set to output audio data for receiver unit assigned channels. The transmitter includes parallel data respectively representing a plurality of audio data channels in each data packet. The data packets are broadcast wirelessly with known, predetermined packets including a timing marker. Each receiver unit receives the broadcast data packets and selects the parallel data respectively representing the receiver unit assigned audio data channel. The receiver unit outputs the selected data synchronized to the receipt of the timing marker by the receiving unit.
