Abstract

A video coding method, a video decoding method, and a related apparatus. One video decoding method may comprise: obtaining a code stream, the code stream carrying first indication information, the first indication information being used for indicating a limitation condition for time domain motion vector prediction of an image of a second type in the code stream, the image of the second type being a non-basic vision image in the code stream, and an image of a first type being a basic vision image in the code stream, or the image of the second type being a non-basic layer image in the code stream, and an image of a first type being a basic layer image in the code stream; decoding the image of the first type in the code stream; and decoding the image of the second type in the code stream according to the limitation condition and the decoded image of the first type. The technical solution provided by embodiments of the present invention helps reduce storage overheads of the coding / decoding device.

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 High Efficient Video Coding (HEVC, High Efficient Video Coding) standards was initiated as needed. [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...
