| Experimental transmission system |
STRL has developed a binocular 3D HDTV transmission system. This system was used in a 3D HDTV transmission experiment on a network between Okayama and Tokyo (approx. 750 km) on November 30, 2001*.
The transmission system, which employs MPEG2 coding technology, compresses individual images for the left and right eye with a bit rate of 22.5 Mbps and puts multiplex time stamps on each image. It also incorporates a reception system that utilizes these multiplexed time stamps to synchronize the left and right eye's images. This enables a 3D presentation without a time gap between the left and right images. The experiment was conducted using a server, at TELEPORT Okayama**, containing compressed 3D HDTV contents, a reception system in KDDI Corporation's Otemachi building (Tokyo) and NHK's Okayama station. The reception system in Tokyo was connected with the server by an IPv6 network.

The success of this experiment showed that it is now technically
feasible to transmit 3D HDTV contents to the several dozen 3D HDTV
exhibition facilities throughout Japan. Since this system is applicable
to other digital transmission paths, such as communications satellites
as well as wired networks, a wide range of future applications can
be expected.
* This experiment was conducted together with the KDDI Corporation, the Communication Research Laboratory (CRL), the Telecommunications Advancement Organization of Japan (TAO), NHK Technical Services, Inc., and NHK Okayama.
** An information network facility operated by Okayama Prefectural Government
