Abstract
The authors modify the conventional DPCM framework of motion-compensated video coding to improve its error resilience in a packet loss environment. The authors propose a system with two decoding modes based on whether a packet is lost or not, so as to minimize the combined distortion due to quantization and transmission errors.
