Computing rate-distortion optimized policies for hybrid receiver/sender driven streaming of multimedia

We consider the problem of streaming packetized media over

the Internet through an intermediate proxy server to a client,

in a rate-distortion optimized way. The proxy employs a hybrid

receiver/sender driven transmission scheme to communicate

with both the media server and the client. Computing the

optimal transmission policy for the proxy involves estimation

of the probability that a single packet will be communicated to

the client in error as a function of the expected redundancy (or

cost) used to communicate the packet. In this paper, we show

how to compute this error-cost function, and thereby optimize

the proxy's transmission policy.
