  • Patent number: 11979599
    Abstract: A method of performing motion vector prediction for coding video data is disclosed. A full precision motion vector mv is determined for generating a prediction for video block in a first picture. A rounded motion vector rmv having a less precision than the full precision motion vector mv is stored. A motion vector predictor candidate is generated for a video block in a second picture from the stored motion vector.

  • Publication number: 20240048697
    Abstract: A method of filtering reconstructed video data is provided. The method receives an array of reconstructed luma samples including a P-block and a Q-block that are both adjacent to an intra sub-partitions (ISP) edge, and determines a first maximum filter length based on whether a first size of an edge of one of the P-block and the Q-block is less than 32. The edge of the one of the P-block and the Q-block is perpendicular to the ISP edge. The method further deblocks the array of the reconstructed luma samples based on the determined first maximum filter length.

  • Patent number: 11889074
    Abstract: A method of coding of video data is disclosed. According to the method, a predicted luma quantization parameter is derived and a luma quantization parameter is generated. The predicted luma quantization parameter is derived by using a tree type specifying whether a single tree or a dual tree is used to partition a coding tree. The luma quantization parameter is generated by using the predicted luma quantization parameter. The predicted luma quantization parameter is set equal to a luma quantization parameter of a coding unit containing a luma coding block covering a neighbouring location by using a current quantization group and a neighbouring block availability.
