Abstract

This paper first introduces an asymmetric tree structure for utilization with an error resilient form 3-D SPIHT, called ERC-SPIHT. Then, we present a fast error concealment scheme, borrowed from Rane et al.'s work with images, for embedded video bitstream using ERC-SPIHT. In addition to using simple averaging method in the root subband, we detect the presence or absence of edges in the lost block of every image. Then we use an interpolation scheme to recover the lost edge information.
