A method and an apparatus for managing domains are provided. The method of managing one or more domains performed by a domain manager located in a home network includes determining whether to register a first device located in the home network to a domain, and providing data required to share content between the first device and a second device registered to the domain according to the determination. In the method and apparatus, content can be shared by connecting the devices with one another including a user, and the burden of content providers for management can be reduced.

摘要:
An apparatus and method for protecting digital content in a digital rights management (DRM) system. In the apparatus and method, usage rules for respective content parts included in a first content file are determined based on plural items of information in the first content file, and a second content file complying with the usage rules is generated. Accordingly, it is possible to allow a user to use only that part of the content included in an externally received content file, which the user has a right to use.

Provided are a method and apparatus for acquiring data regarding a domain for the protection of digital content, and more particularly, a method and apparatus for acquiring domain information and domain-related data in which content received from an external source is converted into content that complies with a set of rules of a digital rights management (DRM) system and a license for the use of the result of the conversion is issued by receiving domain information including a domain key identifier from a domain information providing apparatus and receiving an updated domain key that is a valid domain key currently being used in a domain from a DRM object providing apparatus.

A method and an apparatus for transmitting content from a first device that joins a domain to a second device that does not join the domain are provided. If the second device which does not join the domain is adjacent to the first device which joins the domain, by encrypting a content key corresponding to the content to be transmitted to the second device which does not join the domain using a key of the second device which does not join the domain, and then transmitting the content and the encrypted content key to the second device which does not join the domain, the second device which does not join the domain can use the content having an access authority limitation, which can be used by only devices which join the domain.

A method and apparatus for protecting digital content in a digital rights management (DRM) system. The method of re-importing a second content file, which was imported from a first content file, as a third content file, includes determining whether to allow the re-importing of the second content file based on a difference between a current usage bind of the content determined in an import process and an original usage bind of the content and changing a usage bind of the content from the current usage bind to the original usage bind based on the result of determination. Therefore, when the usage bind of content, which had to be a domain bound, was inevitably determined to be a device bound due to a situation at the time of a content import process, the content can be freely used in the domain bound, which is the original usage bind of the content, according to usage constraints information (UCI) of the content.
