摘要
为了提高多源流媒体课件的质量,本文研究了Advanced Streaming Format和Real Media等流媒体的同步切割技术和多流合并技术,提出了流媒体编辑的关键帧微调技术,设计了两种同步编辑多源流媒体课件的方法:基于公共参考时间轴的同步编辑方法和基于关键帧的同步编辑方法。开发了一套多源流媒体课件的同步编辑系统,实现了多源流媒体的同步切割和合并。
To improve the quality of multi-source streaming media courseware, this paper studies the technology of synchronization cutting and merging of advanced streaming format and real media. The paper proposes a technology of key frame fine tuning, and designs two synchronization editing methods of multi-source streaming media courseware.. the one is based on common timeline, and the other is based on key frame. The paper also presents a system of multi- source streaming media courseware synchronization editing.
