The One-Seg broadcasting service has made it feasible to view broadcasting on small mobile receivers, such as cellular phones. If a mobile receiver can receive broadcast programs and information tailored to an individual viewer's preferences and viewing environment via the Internet, the attraction of this type of service will increase. At the same time, the viewers' privacy and content copyrights will have to be protected for a broadcasting service linked with communications.
This exhibit introduces user information protection technology to assist users to utilize NHK's programs anytime and anywhere without worry on their mobile receivers. It also introduces content protection technology that lets users view downloaded broadcast programs at their convenience to PC receivers and portable receivers. |
- The user information protection technology will enable access to secure members-only services from a mobile receiver.
- Information provided by the user under the premise that it will be protected appropriately will allow a service provider to provide broadcasting services that reflect the user's preferred genre and other data in their program content.
- Content protection technology based on a domain key*will enable users to transfer content that has been downloaded to a PC receiver to a portable receiver registered at the domain, for viewing at the user's convenience.

We will continue to develop security technology through the verification of user information and content protection technology, so that that our viewers can receive pleasing services with safety and confidence.
The authentication technology for mobile terminal broadcasting services is being jointly researched with KDDI Corporation and KDDI R&D Laboratories Inc. The content protection technology for network-linked broadcasting services is being jointly studied with Nippon Telegraph and Telephone Corporation.
