Publication number: 20230247229Abstract: Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.Type: ApplicationFiled: April 11, 2023Publication date: August 3, 2023Applicants: KOREA ADVANCED INSTITUTE OF SCIENCE AND TECHNOLOGY, KOREAN BROADCASTING SYSTEMInventors: Mun Churl KIM, Bum Shik LEE, Jae Il KIM, Chang Seob PARK, Sang Jin HAHM, In Joon CHO, Keun Sik LEE, Byung Sun KIM
