Abstract: The present disclosure is directed to systems, apparatuses, and methods for wirelessly delivering multi-channel audio over a packet based network with tight synchronization, high fidelity, and/or low delay as described above. The systems can include a source device that provides multi-channel audio to a distributor device, which wirelessly distributes the multi-channel audio over the packet based network to audio rendering devices, referred to as “sink” devices. The distributor device and the sink devices each include a playback clock that is used to read audio samples of the multi-channel audio from a local memory and drive a digital-to-analog converter (DAC) coupled to a speaker to render the audio samples.

Abstract: The subject system allows a source device providing a content stream over a network connection to a sink device to adaptively bypass a transcoding portion of a content processing pipeline when the original content stream, e.g. the non-transcoded content stream, can be decoded by the sink device and/or when no actions that utilize transcoding have been requested for the content stream. The source device may power down the transcoding portion of the content processing pipeline when the transcoding portion is not in use. When an action that utilizes transcoding is requested, and the transcoding portion of the pipeline is being bypassed, the source device may power on the transcoding portion and adaptively modify the pipeline to pass the content stream through the transcoding portion. The source device may provide configuration messages to the sink device when the pipeline is modified to provide information for decoding the transcoded content stream.

Abstract translation: 主题系统允许源设备通过与宿设备的网络连接提供内容流，以在原始内容流（例如，内容流）上自适应地绕过内容处理流水线的代码转换部分。 非转码内容流可以由宿设备解码，和/或当没有为内容流请求使用转码的动作时。 当代码转换部分不使用时，源设备可以断开内容处理流水线的代码转换部分。 当请求利用代码转换的动作，并且流水线的代码转换部分被旁路时，源设备可以启动代码转换部分并自适应地修改流水线以通过代码转换部分传递内容流。 当流水线被修改以提供用于对经转码的内容流进行解码的信息时，源设备可以向宿设备提供配置消息。
