Digital TVs will likely be connected to high-speed broadband networks, to provide high-quality digital video and other services. Programs tailored to the needs of individual viewers can also be provided: a program request service using a network is one such example. Content rights management and protection is an issue when distributing digital content over the Internet. The Internet can be used by anyone, and we can assume that viewing on a device like a PC will be done after copying the content onto an optical disk or other storage medium. By protecting content from unauthorized use, or from illegal copying, broadcasters will feel freer to make more quality programs available for distribution over the Internet.
Our content rights management and protection technology can thus be seen as promoting rich broadcasting content distribution. |
- Our new encryption technology* for distribution increases the communication security compared with conventional methods.
- A license that describes content viewing conditions will give broadcasters the means to provide a wide range of services without imposing any inconvenience on viewers.
- A real-time digital watermarking system for Hi-Vision (HDTV) content has been developed that embeds digital watermarks at the receiver side. This makes tracking easier especially in the case of unauthorized re-distribution by the receiver.

| We will verify the feasibility of these technologies and continue to develop rights management and protection technology that promotes rich information distribution. |
| *ID-based encryption scheme: a scheme that employs a content identifier (ID) as a key for content encryption. Encryption and decryption key generation can be performed independently, ensuring secure content distribution.
