System and method for digital rights management of digital video broadcasting |
摘要 |
A system and method for Digital Right Management (DRM) of Digital Video Broadcasting (DVB). The system for DRM of DVB includes a DVB transmitting device for transmitting content for the DVB and information on user's rights object for the content, and a DVB receiving device for receiving and storing the transmitted content, and playing the stored data in accordance with the information on the user's rights object. A sneak post view problem occurring during the DVB is solved, and thus the digital rights for the DVB content are efficiently protected. In solving the sneak post view problem, the existing rights object and the construction of the security association database can be used, without adding a separate construction. |
