Abstract
Distributed video coding technique(DVC) is needed for several applications with low bit rate or low encoding resources. However, since conventional DVC schemes have performance limitations and so as one of the several methods to overcome this problem and to improve the coding efficiency, DVC scheme with the moving information of side information has been developed. Based on this system, in this paper, an efficient reliability estimation is introduced to evaluate the blocks composing of side information and send these blocks location to the encoder side. Then, these enable the encoder to selectively encode and to improve the coding performance. Experimental results show that the proposed scheme performs better than the conventional coding scheme.
