Abstract

We propose a design of a rate control algorithm for low-delay video transmission over wireless channels. Our objective is to meet delay constraints and to make sure that the decoder buffer does not overflow or underflow. We approach this problem analytically, by studying the leaky bucket model in the variable rate transmission scenario, and deriving sufficient conditions for meeting our objective. We then employ these conditions in the design of the rate control algorithm. We report results obtained by using this algorithm with an MPEG-4 AVC/H.264 encoder and LTE channel simulator as a test platform.
