  Panoramic Video Coding

  Panoramic Video Coding is a data compression and coding technology for users to observe a desired viewpoint within a panoramic video by easily and seamlessly processing only that part of the video. Using the international video compression standard H.264 Multiview Video Coding (MVC) efficient, compression of a huge video image with high quality is possible.

• 

  Our R&D themes related to networks, with a focus on the NGN (Next Generation Network), include: network service technology, to construct a high-quality and economical network; network platform technology and encryption and security technology, to provide secure, reliable and convenient network services; next generation network platform technology, to allow the transmission and circulation of a vast volume of information; and environment and energy technology, to reduce global environmental loads.

    Technologies That Support Triple Play

    Using the GE-PON (Gigabit Ethernet-Passive Optical Network) and an fiber-optic video image distribution system, the NTT Group provides telephone, high-speed Internet and TV services via a single optical fiber with high quality and economically. The GE-PON embeds a technology to secure the bandwidth that each customer needs and a technology for the priority allocation of services. The fiber-optic video distribution system resists the impact of noise and transmission path distortion.

    R&D toward Reduction of Environmental Burden

    To save energy at telecommunications buildings, data centers and offices, the NTT Group researches and develops "High voltage Direct Current Power Feeding System" to achieve highly efficient power supply to telecommunications equipment, and engages in research on telecommunications devices for ultralow electric power consumption. We also promote the optimal use of ICT to quantify the environmental burden reduction effect.

• 

  We are undertaking R&D in the areas of broadband and ubiquitous technology, electronics technology, photonics technology, communications science, physics and materials science to create new principles and concepts that will bring about a dramatic change in society and realize a rich communication society.

  Photonic Crystals

  Using special nanostructures called photonic crystals, various phenomena can be achieved such as strong light confinement, slow light and intriguing negative refraction, all of which are impossible with conventional materials. Using these properties, NTT succeeded in reducing the size and energy consumption of optical devices such as optical switches and semiconductor lasers. NTT's R&D continues toward full-scale optical integration.
