Abstract

The example of the invention discloses a method for concealing image error in a realization of video decoding, which comprises the following steps detecting whether encoding errors are occurred on a slice compressing data information, calculating the total number of the error macro module in the slice compressing data information if the encoding error is detected on the slice compressing the data information, generating a coding flow of a corresponding jumping-macro module according to the total number of the macro module, and encoding a coding flow of a corresponding jumping-macro module. The example of the invention further discloses a video decoder, a segment of a whole Skip code flow are coded by the coder to allocate into a sub-layer encoding to the Slice through the method for concealing image errors in the realization of video decoding and the video decoder which are provided by the invention, under the error condition of the slice compressing data information (Slice Date), thereby realizing the function of repairing error images.

Description

technical field

[0001] The invention relates to a communication application field, in particular to a method for realizing image error concealment in video decoding and a video decoder. Background technique

[0002] H.264 is an international standard format for video coding jointly formulated by the international telecommunication standardization department ITU-T and the international standardization organization ISO / International Electrotechnical Association IEC that formulates MPEG. The original intention of the H.264 standard was to develop a new video coding standard to achieve high video compression ratio, high image quality, and good network adaptability. H.264 is also known as MPEG-4AVC ("Moving Picture Experts Group-4 Advanced Video Coding") or MPEG-4Part10.

[0003] H.264 is a video compression standard proposed by the Joint Video Team (JVT). H.264 decoding is mainly divided into a video sequence (Sequence) layer, an image (Picture) layer, and a slice header from t...
