High quality video and audio distribution service is one of the most promising network applications for the broadband network. The deployment of digital cinema is stimulating many advanced applications that will use higher definition imaging systems beyond HDTV. The near-term video format called "4K"1) has been defined as for digital cinema with a resolution of 4Kx2K pixels. The large numbers of movie theaters with pre-installed video projectors, large screens and audio systems, significantly decreases the cost of offering special, public live views of musicals and sports games (Fig.1). While current live viewing events offer HD quality video, commercial 4K video devices are rapidly becoming so popular that the live streaming format is about to shift to 4K. However, even higher definition TV systems of 8Kx4K pixel video, cameras, displays and CODEC, called Super Hi-Vision (SHV)2) have been developed that will enable even more realistic live view services. The cost of networks remains a steep barrier to these live view services. When 8K videos are compressed for transmission over IP networks, the bandwidth of about 300 Mbps is required even though the videos are efficiently compressed by MPEG4-AVC/H.264. Dedicated optical fiber lines have the best quality in terms of stability during transmission, monitoring of network condition, etc. Unfortunately, dedicated lines are designed for permanent and long term use, so they are not suitable for the intermittent live view services. The most promising solution for connecting event venues is to use shared networks. Typical examples of shared networks that offer IP packet transmission rates of over 100 Mbps are the research and education (R&E) networks such as Internet23). Services based on commercial shared networks are now being offered. These broadband network connections are less expensive than dedicated services. The common problem when we use shared networks is the service quality problems caused by the relatively high packet loss rate and packer jitter. In order to resolve this problem, we have developed a high-speed reliable IP transmission system, which ensures network reliability over shared IP networks lying multiple domains. In this paper, we describe this transmission system and an experiment conducted on multi-domain global R&E networks to evaluate the feasibility of the Abstract We have developed a high-speed reliable IP transmission system for the live streaming of video content beyond HDTV. Secure IP Terminator is a key technology that consists of high-efficiency forward error correction, low jitter IP packet control and real-time encryption. The IP terminator offers extremely stable video transmission on shared networks constructed by multi-domain research and educational networks throughout the world. We verify system performance by transmiting coded Super Hi-Vision signals from London to Tokyo.
