摘要： In video encoding, the video frames are spatio-temporally filtered for reduction of spatial and temporal redundancy before they are entropy encoded. Known filtering schemes consider temporally successive frames and are static. It is probable but not necessary that successive frames are most efficient to encode. Therefore, a plurality or all possible frame order permutations are considered for a group of frames (GOP) and evaluated based on a global criterion, which is the sum of local criterion values computed over disjoint sets of successive frames considered in the new order. The local criterion value is deduced from motion estimation processed on each considered set of frames. The best ordering is chosen as the one that minimizes the global criterion value.

摘要： To preserve backward compatibility with a non-HDR device or service, an HDR picture may be represented using a modulation value and an SDR picture representative of the HDR picture. The modulation value and the SDR picture can then be encoded into the bitstream. At the receiving side, the modulation value and the SDR picture can be decoded. Based on the modulation value, the SDR picture can be mapped to a decoded HDR picture. For a non-HDR device or service, the modulation value information may be discarded and only the SDR picture is decoded. In particular, the modulation value may be implicitly signaled, using quad-tree representation information, intra coding information, inter partition mode information or motion vector residual information.
