摘要 Wyner-Ziv视频编码是一种典型的分布式视频编码(DVC)方案,边信息的重建质量对整个Wyner-Ziv系统的性能至关重要.在边信息的重建过程中,引入了H.264中的7种块模式,研究了不同的块模式对边信息质量的影响.分析及实验结果表明,最理想的块模式为8×8.这一结论对以后的DVC研究具有重要的参考价值. Wyner-Ziv video coding is a typical scheme of Distributed Video Coding （DVC）. The quality of the reconstruction of side information is crucial to the performance of the whole Wyner-Ziv system. In the reconstruction of the side information, 7 block modes of H. 264 are applied. The effects of different block mode on the side information quality are studied. Analysis and experiment show that the optimal block mode is 8 × 8. The conclusion will provide a strong reference for the researcher of DVC.
