Error resilience and recovery in streaming of embedded video
The three-dimensional (3-D) SPIHT coder is a scalable or embedded coder that has proved its efficiency and its real-time capability in compression of video. A forward-error-correcting (FEC) channel (RCPC) code combined with a single ARQ (automatic-repeat-request) proved to be an effective means for protecting the bitstream. There were two problems with this scheme: the noiseless reverse channel ARQ may not be feasible in practice; and, in the absence of channel coding and ARQ, the decoded sequence was hopelessly corrupted even for relatively clean channels. In this paper, we introduce a new method of partitioning wavelet coefficients into spatio-temporal (s-t) tree blocks to achieve error resilience. Each of these s-t blocks correspond to the full 3-D image region, because roots of these trees are Preprint submitted to Elsevier Science 14 December 2001
