Description
Summary:The research on distributed video coding (DVC) has been increasingly popular in recent times due to its promising features. Primarily it modifies the complexity balance between the encoder and decoder in the traditional video coding architecture. In this paper, we present a novel architecture for the DVC codec involving a pixel interleaver/de-interleaver stage. This modification enables the exploitation of the unequal distribution of motion levels on the frame to improve the perceptual video quality at the receiver. This modified codec architecture does not involve a reverse channel and hence is suitable for applications with unidirectional channels and also for video storage based applications. The simulation results show a PSNR gain of up to 12 dB compared to a DVC codec not involving pixel interleaver function
