IP-based HDTV broadcasting system architecture with non-stop service availability

This paper presents an architectural concept for IP-based TV broadcasting infrastructure on ISP´s multicast network. As broadcasting grows into an indispensable service menu for ISP, its service availability and independency of content format are crucial issues for smooth business deployment. Hence we newly propose some practical solutions to realize a non-stop IP broadcasting service with simple and content format free server implementation. We also implemented a prototype as an HDTV broadcasting system. The verification results show that our system can compensate about 27,500 packet losses and archive non-stop HDTV broadcasting, even in the event of network layer trouble, without any changes in router implementation.
