  Abstract

To transmit MPEG-2 video on an erroneous channel, a number of techniques for error handling are needed such as error correction, error concealment, etc. Especially, error concealment techniques which can be implemented on receivers independent of transmitters become more important to obtain good video quality. There have been much efforts for developing error concealment techniques with respect to spatiotemporal redundancy and intra-inter frames. In this paper, we propose an efficient effor concealment technique for I-frames(intra-frames) in MPEG-2 video utilizing temporal redundancy. Weconceal erroneous blocks using information of the previous intra frame. Considering the directions of motion vectors in the inter frames, we can obtain a motion vector which can be used for error concealment. This error concealment technique maintains good performance regardless of moving level and provides good results in seriously erroneous conditions.
