Performance evaluation of distributed video coding schemes

Distributed video coding (DVC) has recently been proposed for emerging scenarios, where sources of correlated video do not communicate, as in some video-surveillance applications, or to simplify the coder for video equipment with power consumption constraints. In this paper we propose and compare different DVC schemes. In particular, we propose the use of the wavelet transform and analyze the performance of encoders based on turbo-codes and on a novel modulo-reduction procedure. The proposed schemes do not need feedback from the receiver and use statistical models for the estimation of the required bit-rate. Experimental results show that the proposed schemes have good performance when compared with similar asymmetric video compression schemes, and that DVC can be an interesting option in appropriate scenarios.
