摘要： Systems and methods are provided for encoding raw image content encoded using one or more virtual intra-frames. In an exemplary method, a stream of video content may be encoded to generate compressed video data that includes an intra-flame and a plurality of corresponding inter-frames. The compressed video data may be stored within a buffer, and when the amount of data in the buffer exceeds a threshold value, a virtual intra-frame may be computed based on decoded inter-frame data. The virtual intra-frame may be output for storage in the buffer.

摘要： This disclosure describes techniques for communicating optimal coding parameters between a source device and a sink device. The sink device may receive, in a bitstream, video data and a group of one or more supplemental enhancement information (SEI) messages, wherein each SEI message comprises indications of a set of display capabilities and a set of remapping parameters. The sink device may then, for each SEI message of the group of one or more SEI messages, compare the respective set of display capabilities indicated in the respective SEI message with a target set of display capabilities for the sink device. Responsive to determining that a first set of display capabilities indicated by a first SEI message is compatible with the target set of display capabilities, the sink device may adapt the video data using a respective set of remapping parameters indicated by the first SEI message.

摘要： Several techniques aimed at reducing computational complexity when encoding uses bi-predictively encoded frames (B-frames) are implemented in a video encoder. In an embodiment, B-frames are not used as reference frames for encoding P-frames and other B-frames. Non-use of B-frames allows a de-blocking filter used in the video encoder to be switched off when reconstructing encoded B-frames, and use of a lower complexity filter for fractional-resolution motion search for B-frames. In another embodiment, cost functions used in motion estimation for B-frames are simplified to reduce computational complexity. In one more embodiment, fractional pixel refinement in motion search for B-frames is simplified. In yet another embodiment, predictors used in motion estimation for a macro-block in a P-frame are selected from a B-frame that uses a same reference frame as the P-frame.

摘要： One exemplary video encoding method has the following steps: determining a size of a parallel motion estimation region according to encoding related information; and encoding a plurality of pixels by at least performing motion estimation based on the size of the parallel motion estimation region. One exemplary video decoding method has the following steps: decoding a video parameter stream to obtain a decoded size of a parallel motion estimation region; checking validity of the decoded size of the parallel motion estimation region, and accordingly generating a checking result; when the checking result indicates that the decoded size of the parallel motion estimation region is invalid, entering an error handling process to decide a size of the parallel motion estimation; and decoding a plurality of pixels by at least performing motion estimation based on the decided size of the parallel motion estimation region.
