Design And Implement Of The Digital Rights Manager System In IPTV

With the rapid development of computer network multimedia and communication technology, IPTV (Internet protocol TV) get great progress simultaneity. However, the price and the market of digital media are influenced and controlled by the media content copyright question. Furthermore, the realization of the value of digital media content is suppressed and hindered in the same time. How to guarantee IPTV's safe manufacture, distribution, transmutation and watching, and establish an effective and feasible copyright protective measure are the key points to digital media content-providers.An IPTV copyright management system based on on-line authenticated database was designed and realized in this dissertation after analyzed and researched media content copyright preservation technologies. The designed IPTV copyright management system was composed with three parts: the backstage database system, the onstage issuance and authentication system, and the customer receiving system. The main research contents were described as follows:1. The present situation of IPTV and digital copyright management technologies were analyzed, including the concept and the system structure of IPTV, the key technologies of DRM (Digital Right Management), and so on.2. An IPTV copyright management system was proposed after deeply researched the DRM in IPTV system, includes system structure, work flow and system module functions.3. Three subsystems of the proposed IPTV copyright management system were developed and realized, including the backstage database, the permit authorization server and authentication server.4. The function testing of the three subsystems were finished, through debugging, the validity of this system and the feasibility of this project were substantiated.
