摘　　要：随着教育信息化的发展,云桌面实验室和多媒体广播教学系统成为了远程教学的必要应用。针对传统多媒体广播系统应用在云桌面系统中存在的无法远程教学、云端计算开销过高和网络复用率低的问题,提出了一种基于云端融合和虚拟广播域为架构的广播教学方法。该方法利用终端设备的解码能力降低了云端高额的集中解码开销,利用IP隧道技术创建虚拟广播域来提高广播链路的复用度从而降低网络流量,同时提高教学活动的空间灵活性。With the development of education informatization,cloud desktop laboratory and multimedia broadcasting teaching system have become the necessary applications of distance teaching.Aiming at the problems of remote teaching,high overhead of cloud computing and low network reuse rate of traditional multimedia broadcasting system applied in cloud desktop system,a broadcasting teaching method based on cloud fusion and virtual broadcasting domain architecture was proposed.The method uses the decoding ability of terminal devices to reduce the high cost of centralized decoding in the cloud,to improve the reuse of broadcast links and reduce network traffic by using IP tunnel technology to create virtual broadcast domain,at the same time,the spatial flexibility of teaching activities was improved.
