Problems solved by technology

[0026] 1. It cannot support multicast data transmission across network segments, and the utilization rate of network bandwidth resources is low, which leads to great limitations in the number of end nodes and distribution range that the system can support
[0027] 2. Most synchronous real-time teaching systems directly adopt the multi-point group interaction mechanism in the video conference system, which is not suitable for real-time teaching
Using this interaction mechanism not only increases the complexity of upper-layer management, but also causes unnecessary system resource overhead, especially the overhead of network bandwidth resources.
[0028] 3. Lack of adaptive QoS control mechanism, mainly manifested in: 1. The QoS control mechanism cannot adapt to the dynamic nature of the network state
2. The QoS control mechanism has poor adaptability to the heterogeneity of the distributed environment
[0029] 4. Lack of an automatic courseware generation mechanism, the teaching site can only be saved as a media file, and the courseware that synchronizes the teaching plan with the teaching site cannot be generated

Embodiment Construction

[0075] In order to understand the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings. 5.1 Composition of real-time teaching system

[0076] RealClass, a multimedia real-time teaching system based on IP network, consists of four parts: teaching end, listening end, classroom service center and multipoint control unit (MCU).

[0077] Among them, the teaching terminal refers to the teacher providing real-time video, audio and electronic teaching plans of the teaching site to the listening terminal through the network, and interacts with the listening terminal through tools such as electronic whiteboard, application sharing, and text chat. A teaching platform for controlling the teaching process.

[0078] The teaching terminal realizes the interaction of state and control information with the classroom service center, and can collect, transmit, send, and replay the bottom-level video and aud...
