Abstract
In some video applications such as video surveillance, a simple encoder is preferred and the computational intensive jobs shall be left to the decoder. It is pointed out in Wyner and Ziv’s paper that this goal is achievable by exploiting video source statistics only at the decoder. In many existing Wyner-Ziv video coding schemes, a lot of frames have to be intra coded so that the decoder can derive sufficiently accurate side information from the I frames. In this paper we present a new network-drive Wyner-Ziv method using forward prediction. The basic idea is to perform motion estimation at the decoder and send motion information back to the encoder through the feedback channel. We implement our approach by modifying the H.264 video codec JM8.0 with different configurations. The results show that our proposed approach can improve coding efficiency compared to other Wyner-Ziv video coding schemes.
