Abstract

The invention discloses a system, a device and a method for cascade protection of contents of IPTV service. The system comprises a web server and a multimedia terminal; the web server defines and identifies access right ranks for super link pages requiring cascade protection in an EPG webpage; when receiving a URL request sent by the multimedia terminal, the web server determines whether to transmit data of the super link pages to the multimedia terminal according to right information attached to the request; and when the multimedia terminal receives a super link request of a user, the multimedia terminal detects an identifier of an access right rank of a super link, compares the current access right rank of the terminal with the identified access right rank of the super link, and attaches a detection result or a comparison result serving as right information to the URL request. The invention also provides corresponding device and method. The system, the device and the method can perform the cascade protection on the contents of the IPTV service, and the maintenance cost is extremely low.
