Aspects of a method and system for multiple HCI transport for Bluetooth&#xae; Host controllers may include communicating between a plurality of Bluetooth&#xae; hosts and a single Bluetooth&#xae; host controller by using one or more Bluetooth&#xae; host controller interfaces. Control of the Bluetooth&#xae; host controller interfaces may be assigned to one or more of the Bluetooth&#xae; hosts. Control of the Bluetooth&#xae; host controller interfaces may be switched among different Bluetooth&#xae; hosts using various protocol commands may be used to communicate between Bluetooth&#xae; hosts to control switching. Communications between Bluetooth&#xae; hosts may occur over interfaces different from the Bluetooth&#xae; host controller interfaces. Switching may occur without resetting the Bluetooth&#xae; hosts and Bluetooth&#xae; host controller.

Method and system for multiple HCI transport for bluetooth host controllers

A system and method for discarding or inserting audio frames in a jitter buffer is described. The system and method provides improved audio quality as compared to conventional jitter buffer management systems. In one embodiment, buffer control logic determines whether to discard audio frames to be stored in a jitter buffer or to insert audio frames among audio frames to be output from a jitter buffer based not only on the number of audio frames currently stored in the jitter buffer but also based on the power of the current audio frame to be stored in or output from the jitter buffer. The system and method is generally applicable to any wireless or wired communication system in which audio signals are transmitted between entities operating in different clock domains.

Jitter buffer adaptation based on audio content

A system and method is described herein in which an audio source wirelessly transmits audio content to a first audio sink over one wireless link and to a second audio sink over another wireless link. The two audio sinks also exchange forward error correction (FEC) streams over a link between the two audio sinks, wherein the FEC streams are generated by FEC encoding the audio content received from the audio source. The audio sinks advantageously use the exchanged FEC information to synchronize the playback of the audio content as well as to improve the robustness of the wireless links with the audio source in a manner that does not consume additional bandwidth on those links.

Dual streaming with exchange of FEC streams by audio sinks

A system and method is described herein in which an audio source wirelessly transmits audio content to a first audio sink over one wireless link and to a second audio sink over another wireless link. The two audio sinks also exchange forward error correction (FEC) streams over a wireless link between the two audio sinks, wherein the FEC streams are generated by FEC encoding the audio content received from the audio source. The audio sinks advantageously use the exchanged FEC information to synchronize the playback of the audio content as well as to improve the robustness of the wireless links with the audio source in a manner that does not consume additional bandwidth on those links.
