| Abstract;We have previously developed a prototype SHD (Super High Definition) digital cinema distribution system that contains a PC video server, a JPEG2000 real-time decoder, and an SHD D-ILA projector. By using an enlarged TCP window, multiple TCP streams, and a shaping control function, we succeeded in achieving real-time streaming of SHD movie data at 300Mbps over a fast long-distance (3000km) network. However, since UDP is more suitable than TCP for fast long-distance streaming, we have recently developed an SHD digital cinema UDP relay system, in which UDP is used for transmission over a fast long-distance network. We also improved the decoder performance to show movies with image quality of 450Mbps or higher. By using four server-side-proxy/decoder-side-proxy pairs, 450Mbps movie data streams could be transmitted. (author abst.) |
