Globally Optimal Uneven Error-Protected Packetization of Scalable Code Streams

In this paper, we present a family of new algorithms for rate-fidelity optimal packetization of scalable source bit streams with uneven error protection. In the most general setting where no assumption is made on the probability function of packet loss or on the rate-fidelity function of the scalable code stream, one of our algorithms can find the globally optimal solution to the problem in $O(N^{2}L^{2})$ time, compared to a previously …
