摘　　要：介绍了校园网络教学媒体同步直播系统的设计目标、设计方法和实现步骤。采用先进的流媒体传输技术,基于跨平台Web数据直播技术,实时采集直播现场的音视频信号,并通过IP网络实时地将这些现场信息直播出去。通过基于Web的同步媒体技术,把视频/音频信号与课件数据完整同步地集成在一起,实现远程多媒体同步直播和同步录制,生成完整的多媒体课件。The design target,design method and implementation steps of the synchronous live broadcast system in campus network teaching media are introduced. Adopting advanced stream media technology,based on the live broadcasting technology for cross-platform Web data,the live audio and video signals can be collected in real time and broadcasted through IP network. Integrating video/audio signals and courseware data with integrity and synchronization by Web-based synchronous media technology,the synchronous live broadcast and recording of long range multimedia can be achieved,and integrated multimedia courseware can be produced.
