This paper presents an efficient error concealment algorithm for video bitstream over error-prone channel suffering from damage. Moreover, hardware architecture design and chip implementation of the proposed error concealment algorithm are also presented. For spatial error concealment, a mode selection algorithm considering the reuse of intra mode information embedded in bitstream is developed for...
Error concealment techniques are widely used in video decoder with error-prone communication channels. In this paper, an enhanced edge-sensitive processing order for temporal error concealment algorithm is proposed. Side information of neighboring macroblocks of the corrupted macroblocks are considered to derive a suitable processing order for error concealment, and a new motion vector searching algorithm...
Error concealment technique can improve subjective video quality in decoder when the video bitstream is corrupted during transmission. In this paper, a new error concealment algorithm for I-frames is proposed. To achieve perceptually comfortable results, image inpainting algorithm is adopted with structure information generated from edge information. In addition, mixed spatial-temporal inpainting...
