摘 要:为了满足我国专业性院校对大型教学、讲座、招生、体育赛事等全方位直播的需要,根据多媒体技术具有集成性、交互性等特点,充分利用高校的网络基础条件,建立高标准的设计目标及要求,构建网络多媒体导播系统。该系统通过前端高清摄像设备进行视频采集,再通过数据转换、数据传输、数据编辑、视频切换、视频播放及视频同步录制等功能进行高质量集成管理,实现多场所、教室的网络现场直播,并已在首都体育学院的各项活动中取得良好效果。In order to fulfill the requirements of teaching, games, research and enrollment activities live- broadcast in specialized institutes, this paper leverages the characteristics such as integration, interaction from multimedia technology, makes best use of existing infrastructure of the institute, establishes a series of high level targets and requirements, and builds up our own multimedia broadcast system. With the sys- tem,we can control the videos captured by front-end high-resolution network cameras, the data trans- ferred over network, and how the data to be post-edited, video switching, video playing and video synchro- nous recording with confidence. We do achieve the network live broadcast among multiplegymnasiums, different sites,and teaching rooms as expected.
