摘要：
A foreign gateway (FGW) (105) of the present invention obtains, via a terminal device (107), authentication information which proves access authority with respect to a home gateway (HGW) (104). In a case where a player (106) plays back content stored in a media server (103), the FGW (105) is allowed to access the HGW (104) by presenting the authentication information to the HGW (104). If, after the content is viewed and listened to by a user, a certain condition is satisfied (a communication is interrupted between the FGW (105) and the mobile terminal (107), for example), the FGW (105) requests the HGW (104) not to permit access from the FGW (105), and the HGW (104) stops permitting the access from the FGW (105). This makes it possible to realize a gateway device which prevents unintended access from outside by nullifying, at appropriate timing, the access authority of a device outside a network to which the gateway device belongs.
