Abstract
A digital content protection apparatus and method for digital rights management (DRM) are provided in which a content file including a plurality of content parts is imported such that a header is included which stores location information required for decoding each of the content parts. Therefore, the number of content parts constituting the content file can be recognized, and a license that is required for the use of each of the content parts can be acquired by analyzing header information without necessitating the parsing of the transport packets of the content file. Accordingly, preparation time for using content can be reduced.
