Streaming the movies

NTT has succeeded in streaming Super High Definition movies over the Internet at 300Mbit/sec between Chicago and Los Angeles – a distance of more than 3000km.

Nippon Telegraph and Telephone (NTT) has succeeded in streaming Super High Definition (SHD) movies over the Internet at 300Mbit/sec between Chicago and Los Angeles – a distance of more than 3000km. The previous maximum distance achieved was 5 km long (between Iidabashi and Ginza in Tokyo.)

The experiment, conducted on October 28 and 29, was a collaborative effort between NTT’s Network Innovation Laboratories, the Electronic Visualization Laboratory (EVL) in the University of Illinois at Chicago, Northwestern University and the University of Southern California (USC).

It verified the functionality of several technologies used to broadcast the SHD movies, including the traffic control technology, MXQ, and the scalable multicasting technology, Flexcast.

Super High Definition (SHD) movies themselves have at least 2000 scanning lines, and sport the image quality of 35mm film.

MXQ (MaXimal Queuing) is a Traffic Control Technique for IP routers that dynamically prioritises users’ traffic based on their estimated sending rate.

Flexcast (Flexible stream Multicast) is an autonomous-type wide area multipoint transmission technology that can automatically construct and maintain an optimal transmission path according to changes in the number and the location of transmitters and receivers, and in IP network routing.

The results were encouraging for those engineers who will wish to deploy such technology in the future to distribute movies over the Internet.
