Developing communications networks and fundamental technologies to support ubiquitous broadband services
The NTT Group is focusing on technological innovation to develop ubiquitous broadband services in line with its vision to become a services creation group. We have already developed both optical transmission technology that enables faster and higher capacity data transmission, and quality and security technology that bolsters network performance and reliability.
In addition to carrying out basic R&D to develop high-definition video distribution services and enable the distribution of content such as TV programming, advertisements, and music, we are also putting effort into developing data distribution platform technology that hosts essential common features required by e-commerce and content distribution businesses such as digital rights management and distribution.

Developing a platform to enable high-definition video distribution
NTT Cyber Solutions Laboratories researches platform technologies for services that use the NGN, and in fiscal 2008, based on the results of its NGN field trials*, conducted commercial trials of a high-definition video distribution service and an IP retransmission service. This led to the launch of Hikari TV by Internet service provider NTT Plala, an NTT Group company, as a commercial service at the end of March 2008.
* NGN field trials
Trials conducted with trial users to verify technology and assess user needs using a network equipped with features nearly identical to those that will be available on the full NGN service when it is launched.

Field testing of next-generation portal sites
NTT Cyber Solutions Laboratories field tested various next-generation portal site technologies using goo Labs located within NTT Resonant's goo Internet portal site.
Doremiru Map
Visitors to Doremiru Map-enabled websites can virtually experience event venues and other locations over the Internet. The technology automatically displays information about related content on the Internet such as the popularity of content based on word patterns that appear in blogs, and features icons that show content details. In fiscal 2008 goo Labs ran a Doremiru Map field test that provided Internet users with a virtual experience of the 40th Tokyo Motor Show 2007.

Successful optical transmission at world record speeds of 20 terabits per second
NTT Network Innovation Laboratories performed a successful test in March 2007 in which extremely large data packets were transmitted via a single optical fiber at a speed of 20 terabits (approximately 20 trillion bits) per second over a distance of 240 kilometers. Surpassing last year's successful test transmission at 14 Tbps, this year's 20 Tbps speed is equivalent to transmitting roughly 200 high-definition movies in one second.

Even when apart, telephone gives the sense of being in the same room
NTT Communication Science Laboratories has developed the futuristic t-Room telephone which enables communication that, even when far apart, feels just like you are in the same room as the party on the other end of the line. The t-Room telephone was exhibited at the NTT R&D Forum 2008.
