Abstract
This paper proposes a hybrid Wyner-Ziv video coding scheme without requiring the feedback channel which is a limiting factor for many practical applications. In order to remove the feedback channel, we develop a hybrid structure combining the conventional predictive video coding and the Wyner-Ziv video coding schemes. From the information of the neighboring predictive-coded macro blocks, the proposed hybrid scheme estimates the required channel code rate of the Wyner-Ziv coded macro blocks in order to eliminate the requirement of feedback channel. Experiment results indicate that it achieves good coding performance on sequences having linear and slow motion.
