Abstract

The invention discloses a video decoding method, a device and a video repairing device, wherien the video decoding method includes: generating the Slice decoding information after completing the Slice decoding with the destined number; judging whether the Slice with destined number is provided with a false macro block, if true, generating the repairing information of the false macro block, wherein the repairing information includes the indication information of the false macro block; repairing the false macro block indicated by the indication information. The invention can reduce the complexity to realize the video decoding project.

Description

technical field [0001] The invention relates to the field of multimedia technology, in particular to a video decoding method, device and video patching device. Background technique [0002] In video applications, there is a strong correlation between compressed data (code streams), and a code stream error will cause one or several frames of images to not be decoded normally, affecting the visual experience. Regardless of whether in the network transmission or storage process, data errors are unavoidable, especially in the network environment, so most video decoders try to eliminate or weaken the adverse effects of wrong video streams through error masking, and try to provide users with better data. visual experience. [0003] The premise of error concealment is error detection. By analyzing the video protocol, some comparison conditions can be set in the process of syntax analysis and semantic analysis to detect whether there is an error in the video code stream. If an erro...
