Abstract:

The compressed video data is easily disturbed or lost in error prone channel, and the error not only affects the current frame but also propagates to the subsequent frames especially when it occurs in Intra frames. To address this question, we improved a spatial error concealment algorithm, which can be called texture prediction interpolation, based on the research of the video coding standard H.264. It has been demonstrated that this method achieves good perceptual quality.
