New Multiple Description Layered Coding Method For Video Communication

There are two problems in video communication, one is related to heterogeneity of networks, and the other involves reliability of transmission. Layered coding is designed to solve client heterogeneity problems, and multiple description coding is an effective method for robust transmission. Multiple description layered coding (MDLC) of video combines advantages of layered coding and multiple description coding. In this paper, a new MDLC scheme of video sequence is proposed based on macroblock splitting technique. In addition, other three schemes of MDLC are also given based on row-, column-, and frame-decomposition. Experimental results show that the proposed MDLC scheme with macroblock splitting (MDLC-MS) has advantages in adaptability of network heterogeneity and transmission reliability.
