Inner Mongolia Tongliao City Education Live Broadcast System Solution

1. Background of the plan As the pace of education informatization speeds up, the school ’s education method has been reverted to the original face-to-face traditional education method and gradually changed to the method of information education. The implementation of the education informatization project within the network, Inner Mongolia Zhenglian Information Technology Co., Ltd. is responsible for the architecture and construction of the network, using the VIEWGOOD WebLIVE live broadcast system to build a streaming media video platform, the goal is to connect all local educational institutions to the network Finally, a basic framework for regional interconnection, interaction, information exchange, resource sharing and distance education will be formed. The school's education method is gradually changed from the original face-to-face traditional education method to the information-based education method, thereby improving the overall teaching quality and teaching efficiency of Tongliao City.

Second, the specific needs of users.
1. Use the platform to publish the teaching sites of various schools on the metropolitan area network, so that students from all schools in Tongliao City can learn through the network to form a large-scale network teaching platform.
2. Students do not need any cache when requesting streaming media services, on-demand, almost no delay, and the playback of sound and video is always smooth and continuous, without pauses, no mosaic, jitter and discontinuity And other phenomena.
3. At the same time of live broadcasting, record the lecture content so that students can review the lecture content repeatedly.
4. The system must have sufficient stability, security, and reliability to ensure continuous live broadcast in 7 * 24 hours.

6. When broadcasting live, it is necessary to accommodate 3000 people to watch online at the same time.

3. System analysis To broadcast live education live on the metropolitan area network, this requires the system to have the characteristics of high transmission rate, data synchronization, data stream distribution, and high stability. And the best solution to realize the video and audio transmission of the network is the transmission method of streaming media.
Two-way live broadcast in the metropolitan area network, using a publishing server can successfully complete the publishing work, because the school has the requirement to record programs, so there must be a server dedicated to collect and store programs, live broadcast On the system, VIEWGOOD combines its own product characteristics.
