Abstract
A wireless audio system using low overhead in-band control and audio transmission is provided. The wireless audio system includes a first wireless audio device configured to operate separate physical layer channels for audio data and control data, and transmit the audio data and control data using a single wideband carrier. The wireless audio system also includes one or more second wireless audio devices configured to receive the audio data and control data, and execute an instruction based on the control data.
Claims20
A wireless audio device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless audio device to:
- communicate using a frame scheme comprising a plurality of frames, wherein each of the plurality of frames comprises a respective broadcast channel slot;
- receive, via a broadcast channel slot of at least one of the plurality of frames, an indication of a frame scheme parameter;
- receive, via a common control channel slot, an indication of a control channel pair allocation;
- and
- communicate, via a control channel that is based on the frame scheme parameter and the control channel pair allocation, control data.
A method comprising:
- communicating, by a wireless audio device, using a frame scheme comprising a plurality of frames, wherein each of the plurality of frames comprises a respective broadcast channel slot;
- receiving, via a broadcast channel slot of at least one of the plurality of frames, an indication of a frame scheme parameter;
- receiving, via a common control channel slot, an indication of a control channel pair allocation;
- and
- communicating, via a control channel that is based on the frame scheme parameter and the control channel pair allocation, control data.
A non-transitory computer readable medium storing instructions that, when executed, cause:
- communicating, by a wireless audio device, using a frame scheme comprising a plurality of frames, wherein each of the plurality of frames comprises a respective broadcast channel slot;
- receiving, via a broadcast channel slot of at least one of the plurality of frames, an indication of a frame scheme parameter;
- receiving, via a common control channel slot, an indication of a control channel pair allocation;
- and
- communicating, via a control channel that is based on the frame scheme parameter and the control channel pair allocation, control data.
