Switchable chroma sampling for wireless display

At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by a video transmitter, cause the video transmitter to:

• generate a primary bitstream based on a video signal, wherein the primary bitstream is encoded with subsampled chroma information;
• detect a static condition with respect to the video signal;
• generate, in response to the static condition, a plurality of auxiliary bitstreams based on the video signal, wherein each of the plurality of auxiliary bitstreams is to be encoded with full resolution chroma information;
• mark a first auxiliary bitstream and a second auxiliary bitstream in the plurality of auxiliary bitstreams with a first process identifier;
• and
• mark the primary bitstream with a second process identifier, wherein the first process identifier and the second process identifier are different from one another.

A video receiver apparatus comprising:

• a header analyzer to detect shared timestamp information in (i) a primary bitstream encoded with luma information and subsampled chroma information, (ii) a first auxiliary bitstream encoded with first full resolution chroma information, and (iii) a second auxiliary bitstream encoded with second full resolution chroma information;
• a channel monitor to detect that the first and second auxiliary bitstreams are associated with the primary bitstream, based on detection of the shared timestamp;
• a decoder communicatively coupled to the channel monitor, the decoder to decode the primary bitstream and the first and second auxiliary bitstreams to obtain the luma information and the first and second full resolution chroma information;
• and
• a multiplexer communicatively coupled to the decoder, the multiplexer to multiplex the luma information with the first and second full resolution chroma information.

At least one non-transitory computer readable storage medium comprising a set of instructions, which when executed by a video receiver, cause the video receiver to:

• detect a first process identifier associated with a first auxiliary bitstream and a second auxiliary bitstream in a plurality of auxiliary bitstreams;
• detect a second process identifier associated with a primary bitstream;
• detect that the plurality of auxiliary bitstreams are associated with the primary bitstream, based at least in part on the one or more first process identifier and the second process identifier, wherein the primary bitstream is to be encoded with luma information and subsampled chroma information and each of the plurality of auxiliary bitstreams is to be encoded with full resolution chroma information;
• decode the primary bitstream and the plurality of auxiliary bitstreams to obtain the luma information and the full resolution chroma information;
• and
• multiplex the luma information with the full resolution chroma information.
