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.

Abstract: One embodiment provides an apparatus. The apparatus includes a graphics processor and power management logic. The graphics processor includes display engine logic and encoder logic. The power management logic is to adjust an operating frequency of the encoder logic based, at least in part, on an encode time duration and based, at least in part, on a frame period.

Abstract: Techniques related to video coding with a multi-pass prediction mode decision pipeline.

Abstract: Techniques related to intra coding performance enhancements discussed. Such techniques may include determining intra coding modes based in part on processing performance costs associated with available intra modes and/or generating a block encode order based on intra coding modes, performing encoding, and re-ordering the encoded blocks to a default coding order for bitstream insertion.

Abstract: Techniques related to determining partition modes and transform sizes for video coding are discussed. Such techniques may include determining a portion of a video frame is flat and bypassing an inter-prediction partition check and/or a transform size check for the portion of the video frame based on the portion of the video frame being flat.
