摘要： A relay network of wireless devices extends the range of synchronized playback of broadcast audio signals. A method for delivering isochronous data using a relay network includes receiving first data of an isochronous data stream from a first wireless communications device of the relay network having a first presentation delay. The first data is received by a second wireless communications device of the relay network having a second presentation delay. The method includes presenting the first data by the first wireless communications device and the second wireless communications device at a time after transmission of the first data in a second isochronous data stream by the second wireless communications device. The first data may be presented by each wireless communications device in the relay network after transmission of the first data by a last wireless communications device in the relay network.

摘要： A multi-protocol wireless communications system uses prioritization of isochronous streams to increase the reliability and improve bandwidth utilization. Placement of subevents in an isochronous interval according to link quality reduces fragmentation of the isochronous interval. A method for multi-protocol communications between wireless communications devices using a wireless communications interface includes placing in an isochronous group event, by a first wireless communications device, at least one subevent for each isochronous stream of a plurality of isochronous streams of an isochronous group based on a historical retransmission rate for each isochronous stream of the plurality of isochronous streams. The method may include counting retransmissions for each isochronous stream of the plurality of isochronous streams to thereby determine the historical retransmission rate for each isochronous stream of the plurality of isochronous streams.

摘要： An isochronous channel extension technique transmits asynchronous data using an isochronous channel to reduce or eliminate latency of asynchronous data transfers when asynchronous events and isochronous events with the same peer conflict. A method includes transmitting by a first device, a first data stream using a first channel and a second data stream using a second channel. The first channel has a first interval of first connection events and the second channel has a second interval of second connection events. The first connection events include a first conflicting connection event conflicting with a second conflicting connection event of the second connection events. A first packet of the first data stream associated with the first conflicting connection event is transmitted in the first conflicting connection event and a second packet of the second channel associated with the second conflicting connection event is transmitted in the first conflicting connection event.

摘要： A retry technique reduces or eliminates redundant transmit streams and redundant retransmissions when multiple devices are listening to the same audio stream. The retry techniques reduce power consumption and reduce airtime usage. The retry technique includes communicating data using a hybrid isochronous group including a plurality of broadcast isochronous streams from a source device to a plurality of sink devices. The hybrid isochronous group includes, for each broadcast isochronous stream, a group of connected isochronous streams including a connected isochronous stream to the source device from each of the plurality of sink devices. The broadcast isochronous streams communicate the data and the connected isochronous streams communicate acknowledgements of receiving the data.
