This letter proposes a method to retrieve the original image X out of multiple sets of SI (Side Information) in distributed video coding (DVC). Using Turbo decoding methods, the most reliable segments from the decoded Yi's were selected for the composition of Y, whose conditional entropy H(X|Y) became much lower than any individual conditional entropy H(X|Yi). This proposal has improved the peak signal-to-noise ratio (PSNR) by 1.1 to 1.8dB, compared to the conventional single SI-based approach.
