Embodiment approach 1

[0144] Below, refer to the attached Figures 1 to 16 One embodiment of the present invention will be described.

[0145] First, according to figure 1 The configuration of the content distribution system including the gateway device according to the present embodiment will be described.

[0146] figure 1 It is a schematic structure diagram of the content distribution system. The content distribution system includes a home network (hereinafter, abbreviated as HNW) 101 in the user's own home and a foreign network (hereinafter, abbreviated as FNW) 102 in another home visited by the user. HNW 101 is provided with a home gateway (hereinafter, abbreviated as HGW) 104 for managing devices in HNW 101 , and FNW 102 is provided with a foreign gateway (hereinafter, abbreviated as FGW) for managing devices in FNW 102 105.

[0147] Here, for convenience, the HNW 101 in the user's own home and the FNW 102 in another home are described separately, but these names are relative terms. T...

Embodiment approach 2

[0294] In Embodiment 1, the configuration in which the access right is invalidated based on the status of devices such as the mobile terminal 107 and the player 106 existing in the FGN 102 has been described. In contrast, the FGW 105 does not need to invalidate the access right according to the status of the mobile terminal 107 or the player 106 , but may indirectly invalidate the access right according to the status of the HGW 104 . In this embodiment, two patterns will be exemplified.

[0295] Figure 15 It is a diagram showing a schematic configuration of a content distribution system when another "other house" is added in addition to the own house and another house. At this time, the following situation may occur, that is, after the content stored in the media server 103 in the home network 101 (HNW) is accessed by the player 106 through the external network 102 (FNW1) and using the portable terminal 107, the user Move to the external network 109 (FNW2) different from FN...

Abstract

A foreign gateway (FGW) (105) of the present invention obtains through a terminal device (107) authentication information to prove access authority to a home gateway (HGW) (104). Further, in the case where contents stored at a media server (103) are reproduced by a player (106), the FGW (105) shows the authentication information to the HGW (104), and it is allowed to access. After viewing and listening the contents, under a predetermined condition satisfied with impossibility of communication with the terminal device (107) or the like, the FGW (105) requests the HGW (104) not to allow the access from it, and the HGW (104) will not to allow the access from the FGW (105). With this, authority to access to devices in the outside of its belonging network is invalidated at a proper opportunity, so that a gateway device is realized to prevent unintended access from the outside.

Description

technical field [0001] The present invention relates to a content distribution server for distributing content managed by a content providing server to a content playback device, a content providing server, a content distribution system, a content distribution method, a content providing method, a terminal device, a control program, and a computer program. The read recording medium, wherein the content playback device is managed by the content distribution server. Background technique [0002] The basic goal of home network technology is to be able to watch programs recorded by home HDD recorders or digital photos stored in PCs (Personal Computers) through any TV in the home. The term "Location Free" is often used. In addition, standard specifications such as DLNA (Digital Living Network Alliance: Digital Living Network Alliance) are gradually being completed, and various companies are also starting to sell terminal equipment corresponding to DLNA. [0003] In DNLA, conten...
