Abstract: 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.

Abstract: A network video playback method and an apparatus, where location information of an independently decoded frame in a media segment and location information of a non-independently decoded frame that is in the media segment and that references the independently decoded frame are added to a segment index in order to determine a video frame closest to an access time point from the independently decoded frame and the non-independently decoded frame. The independently decoded frame that is referenced by the video frame closest to the access time point is acquired when the video frame closest to the access time point is the non-independently decoded frame, and decoding starts from the video frame closest to the access time point according to the referenced independently decoded frame, and video playback is performed. Hence, access accuracy of network video playback can be improved.
