Abstract

An embodiment of the invention discloses a method for coding videos, a method for decoding the videos and related devices. The method for decoding the videos can include acquiring a code stream; decoding a first type of images in the code stream; and decoding a second type of images in the code stream according to constraints and the decoded first type of images. The code stream carries first indicating information, the first indicating information is used for indicating the prediction constraints for time-domain motion vectors of the second type of images in the code stream, the second type of images are non-basic view images in the code stream, and the first type of images are basic view images in the code stream; or the second type of images are non-basic layer images in the code stream, and the first type of images are basic layer images in the code stream. According to the technical scheme in the embodiment of the invention, the method for coding the videos, the method for decoding the videos and the related devices have the advantage that the storage overhead of coding / decoding equipment is reduced advantageously.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a video encoding method, a video decoding method and related devices. Background technique [0002] With the development of photoelectric acquisition technology and the growing demand for high-definition digital video, the amount of video data is increasing. The limited heterogeneous transmission bandwidth and diversified video applications continue to put forward higher requirements for video coding efficiency. The formulation of the High Efficient Video Coding (HEVC) standard was started due to the need. [0003] The basic principle of video coding and compression is to use the correlation between space domain, time domain and code words to remove redundancy as much as possible. The current popular practice is to use a block-based hybrid video coding framework to achieve video coding compression through steps such as prediction (including intra prediction and ...
