Abstract	Wyner-Ziv video coding is a low complexity video encoding method that exploits source statistics at the decoder and shifts much of the computational complexity from the encoder to the decoder. Many Wyner-Ziv video coding schemes rely on the use of INTRA frames so that the decoder can derive sufficiently accurate side information. In this paper we extend our previous work on Wyner-Ziv coding that uses backward channel aware motion estimation. The basic idea is to perform motion estimation at the decoder and send the motion information back to the encoder through a backward channel. Experimental results show that this method can significantly improve the coding efficiency with a minimal use of the backward channel bandwidth. We also propose an error resilient technique by using error detection and adaptive coding to handle the situation when the backward channel is subject to erasure errors or delays.
