System and method for integrating third-party informatization of IPTV system

The invention discloses a system and a method for integrating third-party informatization of an IPTV (Internet Protocol Television) system. The system comprises an IPTV system, a third-party informatization service system and multiple set top boxes, wherein the set top boxes are connected with the IPTV system and the third-party informatization service system by an IPTV network, respectively. The system and method for integrating third-party informatization of the IPTV (Internet Protocol Television) system can adopt a Java encapsulation technology to achieve an interface authentication mechanism, thus, the private method can be changed into the method of public outward interface by the third-party informatization system during integrating the IPTV system; and dynamic transition of the interface authentication mechanism can be achieved by an Apache URL (Uniform Resource Locator) rewriting technique, therefore the EPG (Electronic Program Guide) of the IPTV system and the EPG of the informatization system can be
