Rate-distortion optimized sender-driven streaming over best-effortnetworks

摘要

This paper addresses the problem of streaming packetized mediaover a lossy packet network, in a rate-distortion optimized way. Out ofall the packets that a sender could transmit at a given transmissionopportunity, we show how the sender should compute which packets, ifany, to transmit in order to meet an average rate constraint whileminimizing the average end-to-end distortion. Experimental results showthat our system has steady-state gains of 3-7 dB or more over systemsthat are not rate-distortion optimized
