Patent number: 12244853Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. Encoding and decoding of a target block are performed using intra-prediction. The intra-prediction is intra-prediction that uses bidirectional intra-prediction and a remaining mode. In bidirectional intra-prediction, a prediction value for a target pixel in the target block is determined based on reference pixels in two directions of bidirectional intra-prediction. In intra-prediction using a remaining mode, the remaining mode indicates remaining intra-prediction modes other than MPMs present in an MPM list.Type: GrantFiled: November 18, 2021Date of Patent: March 4, 2025Assignees: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, HANBAT NATIONAL UNIVERSITY INDUSTRY-ACADEMIC COOPERATION FOUNDATIONInventors: Hyunsuk Ko, Jung-Won Kang, Sung-Chang Lim, Jin-Ho Lee, Ha-Hyun Lee, Dong-San Jun, Hae-Chul Choi, Hui-Yong Kim, A-Ram Back
