This paper describes a 4K SHD (Super High Definition) real-time video streaming system that can encode (JPEG 2000), transmit and display live images at up to 4096 x 2160 pixel resolution and 36-bit color. The total bit rate of a 4K SHD video to be shown at 30 frames per second in 4:4:4 format is 9.5 Gbps. A JPEG 2000 parallel codec reduces this to 200-400 Mbps and allows live image distribution via common 1 Gbps links with the highest image quality and minimal delay. This system makes it feasible to implement networked professional audio/video applications over long-distance IP networks even at SHD quality.
The next generation home network that will accommodate various services with different quality requirements is introduced. Technical study items for realizing this network are described. Current technologies are overviewed to clarify what will need further consideration.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
