Multiple Description Video Coding Based on Frame-Rotation
Multiple Description Coding is an effective way to improve the robustness of real-time data transmission over unreliable channels. In this paper, we propose a novel MDC scheme based on rotation which is compatible with the current video standard. In the MDC approach, two or more independently decodable descriptions of the same data are generated. In the case of two descriptions, one of the descriptions is formed by the original video sequence and the other is formed by the rotated video sequence. The decoder will reconstruct the video sequence according to the different content received. Experimental results show that the performance of the proposed scheme is superior to the classical RS-MDC scheme about 1 dB.
