  • Patent number: 10567751
    Abstract: In one embodiment, a method receives a video bitstream corresponding to compressed video, wherein Filter Unit (FU) based in-loop filtering is allowed in a reconstruction loop associated with the compressed video. The method then derives reconstructed video from the video bitstream, wherein the reconstructed video is partitioned into FUs and derives a merge flag from the video bitstream for each of the FUs, wherein the merge flag indicates whether said each of the FUs is merged with a neighboring FU. The method further receives a merge index from the video bitstream if the merge flag indicates that said each of the FUs is merged, and receives the filter parameters from the video bitstream if the merge flag indicates that said each of the FUs is not merged. Finally, the method applies the in-loop filtering to said each of the FUs using the filter parameters.

  • Patent number: 10511843
    Abstract: A method and apparatus for loop filter processing of video data in a video encoder or decoder are disclosed. Embodiments according to the present invention conditionally allow sharing of loop filter parameters. In one embodiment, sharing of loop filter information between the current block and a neighboring block is determined according to a condition. If the condition indicates that sharing of loop filter information is allowed, a merge flag is coded and incorporated in the video bitstream in an encoder, and a merge flag is parsed from the video bitstream and decoded in a decoder. In one embodiment, the condition depends on region partitioning of the picture, where region partitioning partitions the picture into regions and the region may correspond to a slice or a tile. The condition is set to indicate that sharing of loop filter information is allowed if the block and the neighboring block are in a same slice/tile.
