ABSTRACT:
A DRM method and DRM-enabled mobile device are provided, in which determinations are made as to whether a playback request is input for replaying a media file, and, if so, whether the media file is a rights-protected media file on the basis of a file format of the media file. If the media file is a rights-protected media file, at least one sample playback part of the rights-protected media file is verified and replayed; otherwise, the entire rights-protected media file is replayed.
