Abstract
A wireless audio delivery system and method are disclosed for distributing an audio signal to a plurality of headsets through short range wireless communication channels. An audio delivery method for a short range wireless communication network including a master device and a plurality of slave devices includes selecting, at the master device, one of the slave devices as a primary slave device, assigning a master control to the primary slave device, establishing a communication channel between the master and the slave devices and delivering audio data to the slave devices through the communication channel.
Claims16
An audio delivery method for a short range wireless communication network including a master device and a plurality of slave devices, comprising the steps of:
- selecting, at the master device, one of the slave devices as a primary slave device;
- assigning a master control comprising at least one of an audio data playback control for controlling playback of the audio data and a call control of the master device for controlling a call connection with another telephony device to the primary slave device;
- establishing a communication channel between the master and the slave devices;
- delivering audio data to the slave devices through the communication channel;
- receiving an audio data change request signal from the primary slave device;
- changing the audio data to another audio data;
- and
- transmitting the changed audio data to each of the plurality of slave devices;
- wherein the step of establishing a communication channel between the master and the slave devices comprises the steps of:
- establishing a synchronous connection oriented link and an asynchronous connectionless link between the master device and the primary slave device;
- and
- establishing asynchronous connectionless links between the master device and slave devices except the primary slave device.
An audio delivery system comprising:
- a plurality of slave devices for receiving identical audio data and outputting the audio data as audible sound waves comprising a primary slave device;
- and
- a master device for:
- selecting one of the plurality of slave devices as the primary slave device;
- assigning a master control comprising at least one of an audio data playback control for controlling playback of the audio data and a call control for controlling a call connection with another telephony device to the primary slave device;
- establishing a synchronous connection oriented link and an asynchronous connectionless link between the master device and the primary slave device;
- establishing asynchronous connectionless links between the master device and slave devices except the primary slave device;
- delivering the audio data to the slave devices through the communication channels;
- receiving an audio data change request signal from the primary slave device;
- changing the audio data to another audio data;
- and
- transmitting the changed audio data to each of the plurality of slave devices.
