Abstract
A system and method of transmitting respective audio streams to a plurality of end points, such as headphones, earphones, headsets, speakers, etc. is disclosed. Different audio streams are transmitted to each of the plurality of end points. The end points may be arranged to audibly output received audio streams, and so each end point may audibly output a respective different audio stream, i.e. the respective audio streams may be mutually different from each other.
Claims21
(canceled)
A method for wireless media distribution, the method comprising:
- determining, by a signaling administrator of a source device, first media stream capabilities of a first device that is connected to the source device during a first time period using a Bluetooth protocol;
- determining, by the signaling administrator, second media stream capabilities of a second device that is connected to the source device during the first time period using the Bluetooth protocol;
- allocating, based at least in part on the first media stream capabilities, first bandwidth to a first advanced audio distribution profile (A2DP) that is associated with the first device;
- allocating, based at least in part on the second media stream capabilities, second bandwidth to a second A2DP that is associated with the second device, wherein the combination of first bandwidth and second bandwidth is less than a maximum A2DP bandwidth;
- establishing a first Bluetooth audio channel between the source device and the first device, the first Bluetooth audio channel having the first bandwidth;
- establishing a second Bluetooth audio channel between the source device and the second device, the second Bluetooth audio channel having the second bandwidth;
- sending, during the first time period, a first audio stream from the source device over the first Bluetooth audio channel to the first device;
- and
- sending, during the first time period, a second audio stream from the source device over the second Bluetooth audio channel to the second device, the first audio stream different from the second audio stream.

A source device for wireless media distribution comprising:
- a processor configured to:
- determine, by a signaling administrator of the source device, first media stream capabilities of a first device that is connected to the source device during a first time period using a Bluetooth protocol;
- determine, by the signaling administrator, second media stream capabilities of a second device that is connected to the source device during the first time period using the Bluetooth protocol;
- allocate, based at least in part on the first media stream capabilities, first bandwidth to a first advanced audio distribution profile (A2DP) that is associated with the first device;
- allocate, based at least in part on the second media stream capabilities, second bandwidth to a second A2DP that is associated with the second device, wherein the combination of first bandwidth and second bandwidth is less than a maximum A2DP bandwidth;
- establish a first Bluetooth audio channel between the source device and the first device, the first Bluetooth audio channel having the first bandwidth;
- establish a second Bluetooth audio channel between the source device and the second device, the second Bluetooth audio channel having the second bandwidth;
- send, during the first time period, a first audio stream from the source device over the first Bluetooth audio channel to the first device;
- and
- send, during the first time period, a second audio stream from the source device over the second Bluetooth audio channel to the second device, the first audio stream different from the second audio stream.
