VIDEO ENCODING AND DECODING METHOD, APPARATUS AND SYSTEM

摘要

The present invention discloses a video encoding and decoding method, apparatus and system, where the video encoding method includes: determining an independently decodable view in a to-be-encoded picture according to a configuration file corresponding to the video; dividing the picture into at least two tiles, where an area corresponding to one or more tiles that cover the independently decodable view is an independently decodable area; generating an auxiliary message corresponding to the picture, where the auxiliary message includes a location identifier of the independently decodable area; and encoding all tiles included in the picture to form an encoded video bitstream, where the encoded video bitstream includes the auxiliary message. Decoding this encoded video bitstream can lower a requirement for performance of a decoder and improve decoding efficiency.

1. A video encoding method, wherein a video comprises a picture sequence, comprising:
determining an independently decodable view in a to-be-encoded picture according to a configuration file corresponding to the video; dividing the picture into at least two tiles, wherein an area corresponding to one or more tiles that cover the independently decodable view is an independently decodable area; generating an auxiliary message corresponding to the picture, wherein the auxiliary message comprises a location identifier of the independently decodable area, and the location identifier of the independently decodable area comprises one or more tile identifiers (tile id); and encoding all tiles comprised in the picture to form an encoded video bitstream, wherein the encoded video bitstream comprises the auxiliary message.
