Abstract: Using Distributed Video Coding (DVC), the complex task of exploiting the source statistics can be moved from the encoder to the decoder. Such a DVC decoder needs side information to exploit the statistics. In common DVC codecs, the side information is obtained by interpolating the current frame from already decoded frames. This paper proposes an interpolation technique for the side information that uses motion compensation with sub-pel accuracy, and compares different interpolation filters for calculating the sub-pel values. Using a six tab Wiener filter, we observe a gain of up to 1.8 dB for the DVC coded frames.
