ADAPTIVE TRANSCODING BYPASS SYSTEM

摘要

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.

1. A method comprising:
identifying a content stream for transmission to a device over a network connection established with the device; determining whether an encoding attribute of the content stream is supported by the device based at least in part on at least one capability of the device; transmitting a first configuration message to the device over the network connection; when the encoding attribute of the content stream is supported by the device:
passing the content stream through a content processing pipeline bypassing a transcoding portion of the content processing pipeline;transmitting the content stream to the device over the network connection, wherein the first configuration message comprises first information for decoding the content stream; and when the encoding attribute of the content stream is not supported by the device:
passing the content stream through the content processing pipeline including the transcoding portion of the content processing pipeline to produce a transcoded content stream;transmitting the transcoded content stream to the device over the network connection, wherein the first configuration message comprises second information for decoding the transcoded content stream, the second information being different than the first information.
