Perhaps the major technical problem in streaming media on demand over the Internet is the need to adapt to changing network conditions. This paper investigates the problem of coding rate control, or equivalently quality adaptation, in response to changing network conditions such as the onset of congestion. Using the theory of optimal linear quadratic control, it designs an efficient online rate control algorithm. The paper also argues that the algorithm complements any transport protocol, and it demonstrates that it works effectively with both TCP and TFRC transport protocols.
