Abstract

The invention relates to a video image decoding technology, in particular to a treatment method for an error macro-block in a video image. The invention discloses the treatment method for the error macro-block in the video image with the same background. The technical proposal of the invention is that according to the correlation between a current frame and an anterior frame of the error macro-block and different situations, the error concealment is implemented on the error macro-block. The video image decoding technology has the beneficial effects of fully utilizing the fixed characteristicsof a video monitoring image, considering to the correlation of moving objects in space and the correlation of the moving objects in time and achieving better error concealment effect with lower computational complexity.

Description

technical field [0001] The invention relates to a video image decoding technology, in particular to a processing method for an erroneous macroblock in a video image. Background technique [0002] The application of digital media has penetrated into all fields of society. From home entertainment, security monitoring to radio and television systems, all aspects of people's lives are related to digital media. Digital media products have been widely used in industries such as family, finance, transportation, and safe cities. scale applications. At present, the monitoring system, especially the bank monitoring system, adopts the technology of centralized monitoring. The video data collected by each monitoring point is encoded according to a certain video encoding standard, such as H264, AVS, etc., which are currently popular, and then transmitted to each monitoring center through the network. In the process of transmission, network errors such as packet loss are unavoidable, an...
