Under the NTT R&D vision of creating technologies that lead the world and contributing to the development of society and industry and academic pursuits, approximately 2,500 researchers engage in a wide range of diverse research activities from basic research to R&D, which support operating companies' business development. With R&D as a key driver of the NTT Group's growth capabilities, the NTT Group creates competitive technologies and collaborates with various corporations, universities and research institutions, thereby ensuring ongoing innovation.
Our R&D covers wide technical ﬁelds, from basic leading-edge research producing new principles and breakthroughs, world-class optical components, the NGN and other network technologies, to application services that exploit networks.
The NTT Group, a telecommunications carrier, provides cloud services as comprehensive, end-to-end operations, which include access and other actions that are available on our safe, secure and highly reliable networks and platforms, as well as via applications and various handsets. The NTT Group thus makes concerted efforts to play a part in "cloud networking as a social infrastructure."
Hikari TV brings IP-retransmitted terrestrial digital TV and BS digital programs, multi-channel broadcast programs, and video-on-demand to homes via an optical network. This service incorporates world-leading technologies developed by NTT Laboratories, such as those related to video coding and multicast. The IPTV technology proposed by NTT has been adopted as international standards. We will expand the service to add a bidirectional service, which has become possible with IPTV, and a full-high-de?nition 3D video delivery.
