New H.266/VVC Based Multiple Description
Coding for Robust Video Transmission over ErrorProne Networks.

Abstract
In this paper, we propose a novel multiple
description coding (MDC) method to operate at network edges
for robust video transmission. The proposed MDC method,
named VVC-MDC offers benefits of both the new H.266
Versatile video coding (H.266/VVC) and Distributed video
coding (DVC) standards, which can provide not only higher
performance compared to the traditional MDC methods but
also effective scheme for the error resilience. At the encoder, the
proposed VVC-MDC coder encode the source video sequence
into two descriptions including odd and even subsequences and
then transmit these descriptions to the receiver. At the receiver,
our proposed MDC decoder is designed using a novel WynerZiv (WZ) coding introduced in the DVC to provide a high image
quality for the video sequence. Experimental results show that
the proposed method can achieve a wide range of tradeoffs
between coding efficiency and error resilience, and provide
much better PSNR performance than other conventional MDC
methods.
