RealClass: An Interactive-Enable Multi-Channel Live Teaching System on Overlay Service Network
In this demonstration, a prototype of live teaching system on overlay service network is presented. The system evolves the following novel characteristics: (1) Firstly, an infrastructure-based overlay multicast structure is introduced, providing multi-channel live media delivery with service differentiation on shared overlay service network. (2) Secondly, the system can support two-way interactive media as well as one-way live media at the same time. The enabling technology is a dynamic user interaction adjustment based on pre-reserved resources in the top layers of the tree. In the demonstration, diversified real-time services will be presented, including audio, video, instant message delivery for multi-channel live teaching scenario, and flexible interactive communication for group discussion.
