In this paper, we propose a new rate allocation algorithm for transform domain Wyner-Ziv video coding (WZVC) without feedback. In contrast to conventional video coding, Wyner-Ziv video coding aims to design simple intra-frame encoding and complex inter-frame decoding based on the Slepian-Wolf and Wyner-Ziv distributed source coding theorems. To allocate(More)
In conventional video coding, the complexity of an encoder is generally much higher than that of a decoder because of operations such as motion estimation consume significant computational resources. Such codec architecture is suitable for downlink transmission model of broadcast. However, in the contemporary applications of mobile wireless video uplink(More)
In this paper, we investigate a fundamental issue in the distributed video coding (DVC) that, once resolved, would substantially improve the compression efficiency in DVC. This fundamental issue is the underlining relation between the distribution of the prediction errors and the compression efficiency of DVC. In the current approach to DVC, after the(More)
