Publication number: 20240137511Abstract: Disclosed herein are a video decoding method and apparatus and a video encoding method and apparatus. In video encoding and decoding, multiple partition blocks are generated by splitting a target block. A prediction mode is derived for at least a part of the multiple partition blocks, among the multiple partition blocks, and prediction is performed on the multiple partition blocks based on the derived prediction mode. When prediction is performed on the partition blocks, information related to the target block may be used, and information related to an additional partition block, which is predicted prior to the partition block, may be used.Type: ApplicationFiled: January 4, 2024Publication date: April 25, 2024Applicants: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, INDUSTRY-UNIVERSITY COOPERATION FOUNDATION KOREA AEROSPACE UNIVERSITY, HANBAT NATIONAL UNIVERSITY INDUSTRY-ACADEMIC COOPERATION FOUNDATIONInventors: Jin-Ho LEE, Jung-Won KANG, Hyunsuk KO, Sung-Chang LIM, Dong-San JUN, Ha-Hyun LEE, Seung-Hyun CHO, Hui-Yong KIM, Hae-Chul CHOI, Dae-Hyeok GWON, Jae-Gon KIM, A-Ram BACK

Patent number: 11943447Abstract: Disclosed herein are a decoding method and apparatus and an encoding method and apparatus that perform inter-prediction using a motion vector predictor. For a candidate block in a col picture, a scaled motion vector is generated based on a motion vector of the candidate block. When the scaled motion vector indicates a target block, a motion vector predictor of the target block is generated based on the motion vector of the candidate block. The motion vector predictor is used to derive the motion vector of the target block in a specific inter-prediction mode such as a merge mode and an AMVP mode.Type: GrantFiled: July 13, 2022Date of Patent: March 26, 2024Assignees: ELECTRONICS AND TELECOMMUNICATIONS RESEARCH INSTITUTE, INDUSTRY-ACADEMIA COOPERATION GROUP OF SEJONG UNIVERSITY, INDUSTRY-UNIVERSITY COOPERATION FOUNDATION KOREA AEROSPACE UNIVERSITYInventors: Sung-Chang Lim, Jung-Won Kang, Hyunsuk Ko, Jin-Ho Lee, Ha-Hyun Lee, Dong-San Jun, Hui-Yong Kim, Yung-Lyul Lee, Nam-Uk Kim, Jae-Gon Kim
