Scalable Video Streaming in Wireless Mesh Networks for Education
In this paper, a video streaming system for education based on wireless mesh network is proposed. Wireless mesh network is a self-organizing, selfmanaging and reliable intelligent network which allows educators to deploy a network quickly whenever there is a need. Video streaming plays an important role in this system for multimedia data transmission. This new system adopts the scalable video coding scheme that enables the video server to deliver layered videos to different user groups. In addition, in order to improve the robustness and efficiency of video streaming, a new approach was developed by transferring the important video control parameters by SDP at the beginning and RTCP during video transferring phase. Furthermore, a quality control method was developed to automatically change the output data rate based on network conditions. Real implementation test results show the proposed methods are effective.
