A Cognitive Source Coding scheme for Multiple Description 3DTV transmission

Multiple Description Coding has recently proved to be an effective solution for the robust transmission of 3D video sequences over unreliable channels. The paper presents a novel Cognitive Source Coding scheme that improves the performance of traditional MDC schemes by combining adaptively traditional predictive and Wyner-Ziv codings according to the characteristics of the video sequence and to the channel conditions. The approach is applied to video+depth 3D transmission and permits improving the average PSNR value up to 2.5 dB with respect to traditional MDC schemes.
