为研究一种新的高效的多视点视频编码方法,提高编码效率,并有效地提高视点间随机切换访问的能力,利用H.264中的新技术多参考帧、SP/SI帧、分层B帧编码等,根据时空预测编码结构的方法,提出了一种基于分层B帧并有利于视点间随机切换访问的多视点视频编码方案.实验结果表明,该方案在提高了编码效率的同时,在视点较多的情况下能够有效地提高视点间随机切换访问的能力.

To improve coding efficiency of the multi-view video coding methods,and effectively improve the ability to views random access,a new high-performance multi-view video coding methods is studied.Many new technologies of H.264 such as multiple reference frames,SP/SI flames and hierarchical B pictures and so on is used to propose a novel multi-view coding scheme which is based on hierarchieal B pictures and is conducive to views random access,according to the use of space-time coding structure prediction methods.Finally,experimental results show that the scheme improve the coding efficiency,and in larger views,the scheme effectively improve the ability to views random access at the same time.
