On October 1, 2008, at the annual GLIF meeting, uncompressed 4K digital content was streamed in real time, from CinePOST, a cinema post-production facility at Barrandov Studios in the Czech Republic, to StarLight. An optical multicast device located at StarLight replicated the information and sent it to the GLIF 2008 meeting in Seattle, WA, and to Calit2/UCSD in San Diego, CA. The Czech CLM device is part photonic multicast (replicating) and part electronic for remote switching control via a web interface.
CESNET is a major CineGrid partner. It maintains a CineGrid Exchange node in Prague to further strengthen its relationship with the CineGrid community and to facilitate participation of Czech-based filmmaking and post-production companies in that community. A detailed description of the architecture is here: www.cesnet.cz/doc/techzpravy/2008/cinegrid-node-architecture. The CineGrid Exchange node is composed of a high-performance storage system connected via the Prague MediaNet optical network to various 4K post-processing and rendering systems, both at CESNET and at Czech-based filmmaking companies. There is also a 10Gbps connection to Masaryk University’s Laboratory of Advanced Networking Technologies in Brno. The CineGrid Exchange node relies on CESNET international circuits from (a) Prague to StarLight (Chicago) and (b) Prague to NetherLight (Amsterdam) to interconnect with other CineGrid members.
Note: While this demonstration did not use TransLight/StarLight, it leveraged networking investments from CESNET for international transatlantic connectivity.
