Title:
VIDEO ENCODING AND DECODING METHODS AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/034330
Kind Code:
A1
Abstract:
Techniques for encoding, decoding, and extracting one or more bitstreams to form one or more sub-bitstreams are described. In one example aspect, a method for video or picture processing includes partitioning a picture into one or more tiles and generating one or more bitstreams using one or more configurations based on the one or more tiles. Generating each of the one or more bitstreams includes partitioning each of the one or more tiles into one or more slices, and performing, for each slice among the one or more slices a first encoding step to encode a tile identifier in a header of the slice, and a second encoding step to encode, in the header of the slice, a second address of the slice that indicates a location of the slice in the tile.
