<p>Systems and methods for transmitting audio data and control segment in a single bitstream and reducing audio disturbance associated with the control segment when the bitstream is processed by an audio digital-to-analog converter. The system, according to one aspect, comprises 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, a second processor coupled to the second audio unit and the receiver, and an audio digital-to-analog converter connected to the second processor. The first processor is configured 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. At least one of the first processor and transmitter is configured 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.</p> |
