Abstract	In this paper, we apply the mutual bi-directional frame coding (MB-frame coding) to our previous proposed padding block based Distributed Video Coding (DVC) scheme for performance improvement. Basically, in the MB-frame coding approach, we adopt the mutual forward and backward video sequence frames to process within reference frames in each individual Group of Pictures (GOP) until no skip blocks could be padded at decoder. It is worth to noting that with this approach the computation complexity does not increase at encoder side, which is consistent with the basic concept to meet the low complexity DVC requirement. Indeed, it achieves the overall system performance improvement with the cost of increasing for average 30 % of computation complexity at decoder side. Via computer simulation we show that the experimental results with the MB frame coding approach has about 0.2 dB gain over the one which does not employ the MB-frames coding scheme.
