Buffer constraints in a variable-rate packetized video system

This paper provides an analysis of the buffers in a variable rate video encoding system and provides necessary conditions that need to be met by the channel and the encoder buffer control mechanism in order to ensure that the decoder and encoder buffers do not underflow or overflow. It is also shown that this can be achieved through the monitoring of just the encoder buffer. The paper also provides an algorithm that allows encoders to change their rate, by dynamically changing their logical buffer sizes, and lists the conditions that need to be met prior to the change in channel rate
