Publication number: 20240195983Abstract: Aspects of the disclosure provide a method and an apparatus for video decoding. The apparatus includes processing circuitry receiving prediction information of a plurality of blocks in a current picture from a coded video bitstream. The processing circuitry determines, based on the prediction information, whether at least one of a decoder-side motion vector refinement (DMVR) mode or a bi-directional optical flow (BDOF) mode is allowed for the plurality of blocks. If the DMVR mode or the BDOF mode is allowed for the plurality of blocks, the processing circuitry determines that a plurality of merge with motion vector difference (MMVD) merge flags indicating whether a MMVD mode is applied to the plurality of blocks, respectively, is inferred as false for the plurality of blocks. If the plurality of MMVD merge flags is inferred as false, the processing circuitry reconstructs each block in the plurality of blocks without applying the MMVD mode.Type: ApplicationFiled: January 17, 2024Publication date: June 13, 2024Applicant: TENCENT AMERICA LLCInventors: Xiang LI, Lien-Fei CHEN, Shan LIU

Patent number: 12003748Abstract: A method for video encoding includes determining a parameter corresponding to the coded video bitstream based on a calculated maximum number of candidates. The parameter is in a range from 0 to 5-sps_sbtmvp_enabled_flag, where the sps_sbtmvp_enabled_flag equal to 1 specifies that subblock based temporal motion vector predictors are used. The sps_sbtmvp_enabled_flag equal to 0 specifies that the subblock based temporal motion vector predictors are not used. In response to a current block being in a subblock based prediction mode, the method includes encoding samples of the current block based on a candidate selection from a constructed subblock based merge candidate list of the current block. The constructed subblock based merge candidate list of the current block is constrained by the maximum number of candidates in the subblock based merge candidate lists.Type: GrantFiled: June 30, 2022Date of Patent: June 4, 2024Assignee: TENCENT AMERICA LLCInventors: Guichun Li, Xiang Li, Xiaozhong Xu, Shan Liu
