Paper Abstract

This paper presents a distributed joint source-channel 3D video coding system. Our aim is the design of an efficient coding scheme for stereoscopic video communication over noisy channels that preserves the perceived visual quality while guaranteeing a low computational complexity. The drawback in using stereo sequences is the increased amount of data to be transmitted. Several methods are being used in the literature for encoding stereoscopic video. A significantly different approach respect to traditional video coding has been represented by Distributed Video Coding (DVC), which introduces a flexible architecture with the design of low complex video encoders. In this paper we propose a novel method for joint source-channel coding in a distributed approach. We choose turbo code for our application and study the new setting of distributed joint source channel coding of a video. Turbo code allows to send the minimum amount of data while guaranteeing near channel capacity error correcting performance. In this contribution, the mathematical framework will be fully detailed and tradeoff among redundancy and perceived quality and quality of experience will be analyzed with the aid of numerical experiments.
