Experiments with Delivery of HDTV over IP Networks

We present the design, and preliminary performance results, for a system that transports uncompressed HDTV content over IP networks. Our system is motivated by the growth in use of digital video, and the ever increasing capacity of localand wide-area Internet links. We aim to demonstrate the feasibility of IP as a transport for very high quality video, and to highlight areas where performance bottlenecks exist and further development is needed. To this end, our system is constructed from commodity components, and was tested over existing commercial IP backbone networks. Performance was shown to be good, with the end system being the main limiting factor.
