Abstract
A digital rights management (DRM) apparatus and a DRM method are disclosed. The DRM apparatus includes a DRM packer, a DRM object database, a distribution manager, a tracking recording unit, and an index controller. The DRM packager generates M content objects according to a digital content and outputs M DRM objects. The DRM object database stores the M DRM objects. The distribution manager selects N DRM objects according to request information from a client. M and N are positive integers, and N is less than M. The index controller controls the distribution manager to transmit N content objects to the client according to the tracking record, index information, a control rule, and a rights datum.
