<P>PROBLEM TO BE SOLVED: To surely manage slave receiving devices which have the possibility of acquiring the contents going across a master receiving device. <P>SOLUTION: The system is provided with a center device 100 which transmits the contents; slave receiving devices 300; and a master receiving device 200, which communicates with the center device through a CATV network 30, communicates with the slave devices with a LAN 40, and is provided with a contents storage means 203. The slave receiving devices 300 are provided with an ID transmission means 302 which performs transmission request of the contents to the master device. The master receiving device 200 is provided with a second network connection means 204 which receives the transmission request, and an ID comparison means 205, which decides whether the transmission request is right or not, and so on and transmits the content of the contents storage means 203 to the slave reception devices 300, when it decides that the authentication is right, and transmits to the center device 100 device information about the slave reception device 300 which does not authenticate, when the authentication has not been made; and the center device 100 manages the device information regarding the devices which treat the content. <P>COPYRIGHT: (C)2009,JPO&INPIT |
