Robust Video Transmission over Error-Prone Networks.

Abstract
In this paper, we propose a novel multiple description coding
(MDC) method to enhance the robustness of video transmission
over error-prone networks. The proposed MDC method provides
benefits of both distributed video coding (DVC) and multiple
description coding techniques, which can offer not only higher
performance compared to the conventional MDC methods but also
effective scheme for the error resilience. In the proposed MDC
method, the input video sequence is split into odd and even group
of pictures (GOPs) subsequences, which are independently
encoded using the new H.265/High efficiency video coding
(H.265/HEVC) based DVC technique. Though the codec itself is
not the core novelty of this paper, our proposed codec is the first
MDC codec in literature employing H.265/HEVC based DVC
approaches, thus all results presented in this paper are new.
Experimental results show that the proposed method can achieve a
wide range of tradeoffs between coding efficiency and error
resilience, and provide much better peak signal-to-noise ratio
(PSNR) performance than other conventional MDC methods.
