In this paper, we introduce an analytical expression for the expected distortion of a single layer encoded video bit-stream. Based on the expected distortion model, we propose a d...

A channel code allocation scheme is developed for transmission of video over error-prone channels. The system is designed to minimize the expected distortion of the video under a ...
