Abstract

After the great success of the predictive video coding approach, which led to a number of largely deployed MPEG and ITU-T standards, the video coding research community has been working on a new video coding paradigm, so-called distributed video coding (DVC), which is based on some Information Theory results from the 70s: the Slepian-Wolf and the Wyner-Ziv theorems. The first practical solutions have emerged around 2002 at the Stanford University and the University of California, Berkeley. This talk will address the basics, main solutions and trends on distributed video coding with especial emphasis on the Stanford DVC codec which has deserved a larger research investment. The rate-distortion (RD) performance of a state-of-the-art Stanford based DVC codec will be presented and benchmarked by the relevant alternative standard based video coding solutions. Finally, some trends on the DVC research will be discussed.
