Title
Multiple description video coding and iterative decoding of LDPCA codes with side information
Abstract
In this paper, we propose the use of multiple description coding to increase the robustness of distributed video coding while keeping good rate-distortion performance. The video sequence is structured into key frames and Wyner-Ziv frames. For each type of frame, two descriptions are generated by a multiple description scalar quantizer and sent on a loss-prone channel. When both Wyner-Ziv descriptions are received, they are jointly decoded along with the side information. We investigate the influence of the amount of redundancy and of the iterative decoding of the descriptions on the performance.
