While distributed video coding (DVC) has emerged as a new video coding paradigm, the compression performance of current systems is still low compared to conventional solutions such as H.264/AVC. While the latter uses many coding modes and an efficient mode decision strategy for choosing the best mode, in DVC, only a limited number of modes has been developed so far. Since encoder-side mode decision...
In distributed video coding (DVC), compression is achieved by exploiting correlation between frames at the decoder, instead of at the encoder. More specifically, the decoder uses already decoded frames to generate side information Y for each Wyner-Ziv frame X, and corrects errors in Y using error correcting bits received from the encoder. For efficient use of these bits, the decoder needs information...
Distributed video coding (DVC) targets video coding applications with low encoding complexity by generating a prediction of the video signal at the decoder. One of the most common architectures uses turbo codes to correct errors in this prediction. Unfortunately, a rigorous analysis of turbo coding in the context of DVC is missing. We have targeted one particular aspect of turbo coding: the stopping...
