Publication number: 20240155120Abstract: Implementations of the disclosure provide video processing systems and methods. The video processing method may include receiving, by one or more processors, a video frame of a video for in-loop filtering. For a target pixel of the video frame, the video processing method may further include selecting, by the one or more processors, a bilateral filtering window to perform the in-loop filtering on the target pixel from a group of candidate filtering windows. The group of candidate filtering windows include a plurality of side filtering windows and a full filtering window. The video processing method may also include filtering, by the one or more processors, the target pixel of the video frame using the selected bilateral filtering window.Type: ApplicationFiled: December 22, 2023Publication date: May 9, 2024Applicant: BEIJING DAJIA INTERNET INFORMATION TECHNOLOGY CO., LTD.Inventors: Ning YAN, Xiaoyu Xiu, Che-Wei KUO, Wei CHEN, Yi-Wen Chen, Hong-Jheng Jhu, Xianglin Wang, Bing Yu

Publication number: 20240146906Abstract: A computer system acquires a video bitstream. The video bitstream includes data associated with multiple encoded pictures. Each encoded picture includes one or more coding units (CUs). While decoding a current CU of a picture in the video bitstream, the current CU having a plurality of reference subblocks located in one or more reference pictures, in accordance with a determination that the plurality of reference subblocks satisfy a first set of predefined conditions for enabling a subblock-based temporal motion vector prediction (SbTMVP) mode, the computer system retrieves, from the video bitstream, syntax elements associated with the SbTMVP mode. The computer system then decodes the current CU using the retrieved syntax elements associated with the SbTMVP mode.Type: ApplicationFiled: January 5, 2024Publication date: May 2, 2024Applicant: BEIJING DAJIA INTERNET INFORMATION TECHNOLOGY CO., LTD.Inventors: Che-Wei KUO, Xiaoyu XIU, Yi-Wen CHEN, Xianglin WANG, Hong-Jheng JHU, Wei CHEN, Ning YAN, Bing YU
