Trans-Pacific demo shows viability of real-time 4K collaboration

October 5, 2005

With systems from Silicon Graphics, an international real-time collaborative 4K digital dailies workflow was demonstrated in San Diego at iGrid 2005.

Using a Silicon Graphics Prism visualization system and SGI InfiniteStorage technology provided by SGI to Keio University in Tokyo, super-high definition 4K digital content was encoded with an experimental JPEG 2000 encoder from NTT Network Innovation Labs at 250-, 400Mb/s and transmitted from the digital cinema laboratory at Keio University in Japan via 9000mi of gigabit optical-fiber networks to the California Institute of Telecommunications and Information Technology (Calit2), University of California, San Diego (UCSD).

NTT Labs also provided prototype Flexcast systems that enable multicast delivery of 4K video and audio over traditional unicast networks.

The demonstration of Trans-Pacific digital cinema post-production at iGrid 2005 was a unique experiment meant to simulate film dailies. The experiment emulated a multi-site production digital dailies session scenario, where the cinematographer is on one continent, the colorist on another and the director on his laptop in a screening room.
