Patent ID: 8825497

Claim:
An audio system comprising: a first audio unit; a transmitter coupled to the first audio unit; a receiver coupled to the transmitter; a second audio unit coupled to the receiver; a first processor coupled to at least one of the first audio unit and the transmitter, the first processor adapted to convert audio data associated with audio content to a bitstream comprising audio bits associated with the audio content, receive a control command selected from a plurality of control commands, in response, generate a control segment comprising a preamble and control bits associated with the control command, insert the control segment to the bitstream, and transmit the bitstream to the second audio unit using the transmitter; a second processor coupled to the second audio unit and the receiver, the second processor adapted to monitor the bitstream for the preamble to detect the control segment, and if the control segment is detected, receive the control bits and execute the corresponding control command; and an audio digital-to-analog converter connected to the second processor and adapted to process the bitstream to produce audio associated with the bitstream; wherein at least one of the first processor and the transmitter is adapted to change the oversampling frequency to a selected value while the control segment is being transmitted to generate sufficient bandwidth to send the control segment concurrently with the audio data.
