Research paper thumbnail of ERROR CONCEALMENT TECHNIQUES FOR ENCODED VIDEO STREAMS

In this paper we describe two error-recovery approaches for MPEG encoded video over ATM networks.... more In this paper we describe two error-recovery approaches for MPEG encoded video over ATM networks. The first approach aims at reconstructing each lost pixel by spatial interpolation from the nearest undamaged pixels. The second approach recovers lost macroblocks by minimizing intersample variations within each block and across its boundaries. Moreover, a new technique for packing ATM cells with compressed data is also proposed.
