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 times 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
