Real-Time Streaming of 4K Digital Cinema over Gigabit IP Optical Fiber Networks
Newswise - In a demonstration that could foretell the future of videoconferencing, scientific visualization and digital cinema deployment, scientists from around the world meeting at iGrid 2005 in San Diego were treated to the world's first real-time, international transmission of super high-definition (SHD) 4K digital video. 4K images have roughly 4,000 horizontal pixels - offering approximately four times the resolution of the most widely-used HD television format, and 24 times that of a standard broadcast TV signal.
The 4K transmission linked the University of California, San Diego and Keio University in Tokyo via 15,000 kilometers (roughly 9,000 miles) of gigabit Internet Protocol (IP) optical-fiber networks, and allowed organizers to show attendees the most varied 4K content ever presented at a single event anywhere in the world to date.
Using 4K technology, Keio president Yuichiro Anzai and UCSD Chancellor Marye Anne Fox opened iGrid 2005, a workshop and symposium that brings together the world's leading experts in grid computing and high-bandwidth networking every two years. The week-long event runs Sept. 26-29 at the California Institute for Telecommunications and Information Technology (Calit2) on the UCSD campus in San Diego, CA.
In their remarks, the two leaders emphasized the benefits of networked collaboration between their respective institutions, and called for further cooperation between Calit2 and Keio's Research Institute for Digital Media and Content (DMC).
"This demonstration of trans-Pacific, real-time 4K streaming media pushes the envelope of today's advanced research networks," said Keio president Anzai. "We now know that these networks can reliably carry the world's newest and highest-quality digital media, even over long distances, both live and pre-recorded."
