Yima: A Second Generation of Continuous Media Servers
This paper report on the design, implementation and evaluation of a scalable real-time streaming architecture, termed Yima that enable applications such as video-on-demand and distance learning on a large scale. While Yima incorporates lessons learned from first generation research prototypes, it also complies with industry standards in content format (MP4) and communication protocol (RTP/RTSP). Meanwhile, it distinguishes itself from both research prototypes and commercial products because it incorporates the recent research and it pushes the industry envelope by supporting HDTV and multi-channel panoramic clients. This paper describes the principles of existing approaches both research and commercial and how Yima improves upon them through the research.
