Summary form only given. In this paper, we consider the case of a noisy channel in Wyner-Ziv coding (WZC) and address distributed joint source-channel coding (JSCC), while targeting at video transmission over packet erasure channels. Our idea is to use a single Raptor code, for both SWC and erasure protection. Raptor codes are the latest addition to a family of low-complexity rateless fountain codes which consist of a high-rate precode and an LT code. We use IRA codes as the precode of our Raptor code, as IRA codes are well suited for distributed JSCC. For the decoder design, due to the presence of side information, we develop a new iterative soft-decision Raptor decoder for joint decoding that combines the received packets and the side information.
