Paper Abstract

In this paper, we present an error resilient video coding scheme for wireless video telephony applications that uses feedback to limit error propagation. In conventional feedback-based error resilient schemes, error propagation can significantly degrade visual quality when feedback delay is in the order of a few seconds. We propose a coding structure based on multiple description coding that mitigates error propagation during feedback delay, and uses feedback to adapt its coding structure to effectively limit error propagation. We demonstrate the effectiveness of our approach at different error rates when compared to conventional coding schemes that use feedback.
