摘要
面向网络教育教学视频传输的需求,对视频传输所涉及的视频编码、网络带宽自适应等一些关键技术进行了研究。
Facing the demand of video transmission for network educational teaching, this paper has researched in some crucial technologies for the video transmission such as video coding and bite rate changing for different network bandwidths. With the key regional coding method for the key image optimization coding, and the variable transmission strategy by changing transmission bite rate according to bandwidth, we solve the distance teaching problem of real time in Internet network environmental.
