Video decoding method, decoding device, decoder and electronic equipment

Abstract

This application belongs to the technical field of encoding and decoding, and in particular relates to a video decoding method, a decoding device, a decoder and electronic equipment. The method includes: obtaining a newly decoded knowledge image; judging whether the knowledge image buffer is filled with a preset number of historical knowledge images; If yes, remove at least part of the historical knowledge images in the knowledge image buffer; add newly decoded knowledge images to the knowledge image buffer. The video decoding method in the embodiment of the present application establishes a knowledge image management mechanism to determine the size of the knowledge image decoding buffer and the method for entering and leaving the knowledge image in the buffer. The deterministic management mechanism enables the decoding process of the knowledge image and the decoding process of the main bit stream to be integrated into one decoder, which improves the certainty of the realization process of the knowledge image.

Description

technical field [0001] The present application belongs to the technical field of coding and decoding, and in particular relates to a video decoding method, a decoding device, a decoder and electronic equipment. Background technique [0002] Video images contain a large amount of data, and video pixel data (RGB, YUV, etc.) usually needs to be compressed and encoded before being transmitted or stored. The compressed and encoded data is called a video code stream, and the video code stream is transmitted to the client through a wired or wireless network, and then decoded and watched. [0003] However, in the existing decoding technology, especially in the AVS3 technology, how to save and update the knowledge image after decoding is not constrained by the coding standard, and completely depends on the user to manage it according to the system layer information, resulting in uncertainty in the realization of the knowledge image. , affecting the decoding process.
