Apparatus and method for importing content including plural pieces of usage constraint information

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.
