<p>A digital content usage system is applicable to a content usage apparatus (5) for use of a digital content containing a license machine ID. The system comprises an acquiring part that acquires a unique machine ID of a content usage apparatus (5) which intends to use the digital content, a detecting part that detects the license machine ID from the digital content to be used, a comparing part that compares the acquired unique machine ID with the detected license machine ID and a determining part being operative if the acquired unique machine ID matches with the detected license machine ID for allowing the content usage apparatus (5) to exercise a free use of the digital content. The determining part is also operative if the acquired unique machine ID does not match with the detected license machine ID for restricting the content usage apparatus (5) to exercise only a temporary use of the digital content under a time duration.</p> |
