Publication number: 20230262221Abstract: A method and device for coding and decoding are disclosed. The method includes: dividing a picture to be encoded into several slices, each containing macroblocks continuous in a designated scanning sequence in the picture; dividing slices in the picture into one or more slice sets according to attribute information of the slices, each slice set containing one or more slices; and encoding the slices in the slice sets according to slice and slice set division information to get a coded bit stream of the picture. The decoding method includes: obtaining slice and slice set division information from a bit stream to be decoded and decoding the bit stream according to the obtained slice and slice set division information. The invention improves the performance of video transmission effectively and realizes region based coding. The implementation of coding and decoding is simple and the complexity of coding and decoding systems is reduced.Type: ApplicationFiled: April 18, 2023Publication date: August 17, 2023Applicants: HUAWEI TECHNOLOGIES CO., LTD., TSINGHUA UNIVERSITYInventors: Xiaozhen Zheng, Zhen Mao, Ziyuan Wang, Yun He, Xiaozhong Xu, Jianhua Zheng
