Error resilient video coding for systems with delayed feedback

In systems employing feedback-based error resilience, 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.
