For digital broadcasting of TV-signals over various transmission media like satellite, cable, and terrestrial channels, the MPEG-2 video source coding algorithm will be considered. Since the video-signal is very sensitive to channel disturbances due to variable length coding, a bit- error rate of less than 10-8 has to be guaranteed. Therefore, a powerful error protection scheme is applied in the European TV-Broadcasting Standards. However, in the case of bad reception conditions, e.g. deep fades or impulsive noise, remaining errors even in the highest protected video signal may still occur. With remaining errors in the video signal a good quality of service cannot be guaranteed. Therefore, some post-processing techniques such as error concealment and iterative decoding at the receiver side will be desirable. The aim of this article is to study different error concealment techniques for handling residual channel errors at the receiver side taking into account a real transmission media. For I-pictures, a motion compensated temporal error concealment algorithm is proposed where motion vectors are displaced along the motion direction.
