[0049] First, the configuration of a home network 1 according to the first embodiment will be described with reference to FIG. 1 .

[0050] FIG. 1 is a diagram showing the configuration of a home network 1 according to the first embodiment.

[0051]The home network 1 is a network for realizing content sharing in the home, and is composed of a router 10 , a transmitter 20 , and receivers 30 , 31 , and 32 . The router 10 is uniquely connected to the external network (Internet) of the home network 1 in the home network 1 . The transmitter 20 and receivers 30 , 31 , 32 are connected to the router 10 . The home network 1 is a star network centered on the router 10 .

[0052] The transmitter 20 stores various contents, and receives an authentication request from another device through the router 10 to determine whether the other device is a device in the home network 1 and whether it can share the content stored in the transmitter 20 . When it is determined that the other device ...

[0117] In the second embodiment, differences from the first embodiment will be described.

[0118] In the second embodiment, the transmitter 20 manages the content distribution status of all registered receivers with only one counter when measuring the period during which the receivers can receive content with respect to the receivers allowed to share content. The transmitter 20 performs authentication and RTT verification on the authentication request from the receiver, and when it is determined that content sharing can be permitted, registers the receiver as an authorized receiver. The transmitter 20 sets the upper limit (reception effective period) of the period during which all receivers can receive the content to the common counter at the time when one receiver is registered. That is, the transmitter 20 initializes a common counter corresponding to all registered receivers. The transmitter 20 cancels the registration of all the registered receivers at the time when it is...

Abstract

The present invention provides a content distribution management device that manages content distribution for a receiver which is permitted to share a content stored in a transmitter. The content distribution management device is a content distribution management device that manages content distribution in the case where a transmitter distributes a content to a plurality of receivers, the content distribution management device including a registration information / counter changing unit (205) which sets, in a registration information / counter holding unit (203), a valid reception period which is a maximum length of time for which the receivers can receive the content, the receivers being permitted to share the content, and the registration information / counter changing unit (205) manages, in accordance with a status of distribution of the content from the transmitter, a length of time for which all the receivers permitted to share the content can receive the content.

Description

technical field [0001] The present invention relates to a content distribution management device for managing distribution of content by a transmitter. Background technique [0002] In recent years, devices in the home are connected via a network, and a home network for sharing various contents is gradually realized. As a way to implement a home network, you can consider setting up a router in the home. This router connects devices such as TVs and video recorders (hereinafter referred to as "receivers") and senders such as DVD recorders that store content in a star-shaped manner. connect. Here, make the router the only device in the home connected to the network outside the home. The transmitter has a function of distributing the stored content to the receiver upon request from the receiver. In this way, each receiver can share various contents stored in the transmitter. [0003] On the other hand, from the viewpoint of copyright protection, unlimited sharing of content ...
