Abstract
Based on recent works on source-channel coding for Wyner-Ziv coding, we consider the case with noisy channel in Wyner-Ziv coding and address distributed joint source-channel coding, while targeting at the important application of video transmission over packet erasure channels. The idea is to use a single channel code for both Slepian-Wolf coding (or source coding with side information at the decoder) and erasure protection. We choose Raptor codes - the best approximation to a digital fountain - for the targeted application and study both encoder and decoder designs under the new setting of distributed joint source-channel coding. Our work represents the first in capitalizing the latest in distributed source coding (e.g., Wyner-Ziv video coding) and near-capacity channel coding (e.g., fountain codes) for robust video transmission over erasure channels.
