摘要
随着多媒体技术的兴起。演播教学模式越来越多地取代了传统教学模式。在这种模式中，多媒体信息传输的主要瓶颈便是视频，拥有如此庞大数据量的视频，是限制多媒体技术发展的重要障碍。视频经过压缩后，存储会更方便，且并不影响作品的最终视觉效果。基于此目的。系统地研究了如何利用时间线＋事件＋帧的流来记录演示内容，从而尽可能地将视频数据压缩到最小，在文件大小和画面质量之间达到最佳平衡的问题。
With the rise of multimedia technology,the studio teaching mode more and more replaced the traditional teaching mode. In this model, multimedia video information transmission is the main bottleneck, with such a huge volume of data and video, that is a major obstacle to the development of multimedia technology. After video compression, storage will be more convenient, and does not affect the ultimate visual effects work.For this purpose, the systematic study of the problem is about how to use the stream of time line ＋ event ＋ frame to record the demonstration,and the video data couble be compressed to minimize as much as possible, and between the file size and picture quality couble be achieve the optimum balance.
