Fast R-D Optimal Packetization of Embedded Bitstreams into Independent Source Packets

This work addresses the rate-distortion (R-D) optimal packetization (OP) of embedded bitstreams into independent source packets, in order to limit error propagation in transmission over packet lossy channels. The input embedded stream is assumed to be an interleaving of $K$ independently decodable basic streams. To form $N$ independent source packets, each of $L$ symbols, the set of basic streams is partitioned into $N$ groups. The objective of …
