Abstract

The invention discloses a video decoding method and a video decoder, which are used for receiving video code streams sequentially and decoding and outputting the video code streams. The video decodingmethod comprises the following steps: marking errors; recording error codes in the process of decoding according to the decoding situation; concealing the errors; generating error concealment parameters according to the error codes recorded in the step of marking the errors; and outputting the error concealment parameters and decoded video code stream data according to a receiving sequence.

Description

technical field [0001] The invention relates to the field of video encoding and decoding, in particular to a video decoding method and a video decoder. Background technique [0002] In the field of video coding and decoding, how to efficiently decode the compressed video code stream has always been the unremitting motivation for technicians to explore. [0003] Take the introduction of the MPEG-2 compression standard in 1994 as an example. The MPEG-2 standard is a detailed specification of the compression scheme and system layer for standard digital TV and high-definition TV in various applications. The coding rate ranges from 3 megabits per second to ~ 100 Mbit, the formal specification of the standard is in ISO / IEC13818. MPEG-2 is especially suitable for the coding and transmission of broadcast-level digital TV, and is recognized as the coding standard for SDTV and HDTV. The principle of MPEG-2 image compression is to use two kinds of characteristics in the image: spatia...
