摘要
为了得到更好的压缩性能和网络友好性,最新的视频编码标准H.264提出了很多新的视频编码技术。在对其中的多参考帧技术进行研究的基础上提出了一种参考帧的选取方案。对相邻的两个P帧或I帧进行分析,然后根据分析的结果选取B帧作为参考帧,从而获得较好的压缩性能。该方案采用H.264/AVC的编码器JM12.2实现,并取得了预期的测试结果。
Many new video coding technologies are put forward by the newest standardization H. 264 m enhance compression performance and provide ＂network- friendly＂ representation. A scheme for the referenced frame selection is presented in this paper after a deeply study on the multi referenced frame technology. Analyze the two neighbor intra coding frames, and then decide whether B fame is a referenced fame according m the result. It can be implemented readily with H. 264/AVC code. The experimental results show that the proposed scheme can achieve fine compression efficiency and high view quality.
