Abstract
In the H.264/AVC video codec, a compressed video can be displayed in a real-time channel. The transmission for the video packet may suffer from collision, delay, or loss. There will be some error or lost macro blocks (MBs) in the decoded frame, and these blocks will cause a series of error propagation and low quality in the next decoded frame. To use high correlation between spatial and temporal domains, error concealment is a well-known technique used by the decoder to recover the corrupted or lost information and to prevent from error propagation in the next frame. In this paper, we use image sharpening filter to find the characteristic of a MB and adopt various error concealment methods to conceal the MB adaptively. The game theory is a good tool that helps us select the optimal solution to increase the visual quality and PSNR of the decoded frame. The simulation shows good performance of the proposed error concealment schema.
