20090238375 | 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. | 09-24-2009 |
20100020983 | Wireless speaker dongle with auxiliary audio output - A wireless audio signal transmitter is presented that routes audio signals to either a wired or a wireless sound output device. The transmitter selects whether the audio signal is transmitted over a wireless antenna to a wireless device, or is transmitted to a physically attached device. The transmitter may take the form of a USB dongle or a wireless device charging station. The transmitter detects whether the wireless audio output device is powered on and in communication with the transmitter to determine how to route the audio signal received from the computer. If the wireless audio output device is connected to the transmitter, the audio signal is routed to the wireless audio output device. If there is no connection, then the audio signal is routed to the wired audio output device. | 01-28-2010 |
