Abstract
Methods, apparatuses and systems may provide for a video transmitter that generates a primary bitstream based on a video signal, wherein the primary bitstream is encoded with subsampled chroma information, and detects a static condition with respect to the video signal. Additionally, a plurality of auxiliary bitstreams may be generated, in response to the static condition, based on the video signal. Each of the plurality of auxiliary bitstreams may be encoded with full resolution chroma information. In one example, a video receiver may detect that the auxiliary bitstreams are associated with the primary bitstream, decode the primary bitstream and the plurality of auxiliary bitstreams to obtain luma information and the full resolution chroma information, and multiplex the luma information with the full resolution chroma information.
