Embodiment Construction

[0093] Here, an information distribution system 1 , an embodiment of the present invention, will be described with reference to the drawings.

[0094]

[0095] 1. Information distribution system 1

[0096] FIG. 1 is a system configuration diagram showing the configuration of an information distribution system 1 . As shown in the figure, the information distribution system 1 is composed of a broadcasting station device 10 , a server device 20 , a TV 30 , a PC 40 , and a PDA 50 .

[0097] The broadcast station device 10 is a device installed in a broadcast station. The broadcasting station device 10 includes an antenna, and broadcasts content on digital broadcast waves via the antenna.

[0098] The server device 20 has a function of receiving content broadcast from the broadcasting station device 10 and storing the received content. Also, the server device 20 receives operation request information from the TV 30 , PC 40 , and PDA 50 (hereinafter, these may be collectively r...

Abstract

In order to protect a content holder, a server device (20) holds distribution control information defining a content of the number of terminals to which the same part of the content can be simultaneously distributed. When a reproduction request of the content is received from a plurality of terminals, content distribution to the respective terminals is controlled without exceeding the number of terminals defined in the distribution control information.

Description

technical field [0001] The present invention relates to a technology for distributing information via a network, and particularly relates to a technology for distributing content while protecting the rights of content owners. Background technique [0002] In recent years, digital broadcasting such as BS digital broadcasting, 110-degree CS digital broadcasting, and terrestrial digital broadcasting has started. In these digital broadcasts, in the case of copying digital content (hereinafter referred to as "content") broadcast from a broadcasting station, information with very little deterioration can be obtained. [0003] In order to restrict such copying, copy control information (CCI: Copy Control Information) is assigned to content broadcast from a broadcasting station. As an example of CCI, there is a digital copy control descriptor inserted into the content, and the copy of the content is given "Copy Free (free copy)", "Copy Once (copy once)", and "Copy Never (copy prohi...
