Embodiment Construction

[0095]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0096] First introduce the basic concept of understanding the scheme of the present invention below:

[0097] Largest coding unit (LCU): The smallest picture division unit in high efficiency video coding (HEVC) technology, such as image 3 Small squares in . The LCU can be a 64*64 pixel square. Before the HEVC encoder encodes a frame of pictures, it first divides the picture into a grid with LCU as the unit.

[0098] Coding unit (CU): The encoder dynamic...

Abstract

The invention discloses a video encoding and decoding method, device and system. The video encoding method includes the following steps: determining an independently decodable view in a picture to beencoded according to a configuration file corresponding to a 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 includes a location identifier of the independently decodable area, and the location identifier of the independently decodable area is composed of one or more tile ids; and encoding all tiles included in the picture to form an encoded video code stream, wherein the encoded video code stream includes the auxiliary message. By decoding the encoded video code stream, the performance requirements of a decoder can be reduced, and the decoding efficiency can be improved.

Description

technical field [0001] The present invention relates to image processing technology, in particular to a video coding and decoding method, device and system. Background technique [0002] 3DTV (Three-Dimensional Television, stereoscopic television) is the most common stereoscopic television technology. It displays two independent left and right views on one screen, and the left and right eyes receive different views respectively to achieve a 3D stereoscopic effect. At present, when providing 3DTV services, service providers hope to utilize original 2DTV (Two-Dimensional Television, flat-screen TV) encoding tools and transmission equipment as much as possible, so as to save video production costs and transmission equipment costs. [0003] In order to achieve the above requirements, frame packing (frame packing) 3DTV technology stitches the left and right views into one frame image, and then encodes and transmits it with a 2D encoder and transmission equipment, and adds how to...
