This paper addresses the problem of streaming packetized media over

a lossy packet network, in a rate-distortion optimized way. Out of all the packets that a

sender could transmit at a given transmission opportunity, we show how the sender should

compute which packets, if any, to transmit in order to meet an average rate constraint

while minimizing the average end-to-end distortion. Experimental results show that our

system has steady-state gains of 3–7 dB or more over systems that are not rate-distortion

optimized.
