Live Video Streaming Using P2P and SVC

The research of Video Streaming has often focused on the methodologies of P2P protocols, such as peer selection, network structure, group organization, etc. In addition, streaming mechanism and system deployment are significant to provide a Video Streaming service. Research in this field, however, is scant. On the other hand, the layered video codec provides scalability when environment is divergent due to different transmission rate, computational power, and so on. Recently, Scalable Video Coding (SVC), which is a layered video codec, has been standardized and caught much attention. The study is to explore how to provide Video Streaming service by employing P2P and SVC. A system architecture which involves video layering, dynamic Segment seeding and scheduling, and Segment downloading and sharing is developed. To provide high quality Live or On-demand P2P Video Streaming service, a Video Streaming system, GaiaSharp, is implemented and deployed, and the experience is shown to explain the importance of layered video codec.
