In this paper, a CWE model of the distance education system is provided. In order to enhance the bandwidth utilization factor, a transfer method based on multi-channel is presented. Both the transmission of real-time media stream and time-stamp technologies are introduced to the system to ensure the requirement of real-time characteristic and synchronism, and a simple protocol based on RTP (Real-time Transfer Protocol) and UDP is designed. The method, event simulcast, is also brought forward to reduce the data redundancy and expand the collaboration scale of the system.
