(Concept of Embodiment 1)
[0013]
FIG. 1 is a diagram illustrating an example of the concept of the present embodiment. The concept of the present embodiment will be described with reference to FIG.
[0014]
User A has downloaded from the content distribution server the content of the movie “Star Wars” and an electronic ticket including information (execution range information) for viewing the movie content five times regardless of the type. Using the execution range information included in the electronic ticket, the user watched the movie “Star Wars” twice, but did not wish to view it any more. Since the number of times that the user can view was 5 times, 3 times were left. Therefore, the content of another movie "Matrix" was downloaded and viewed twice using the remaining three execution range information. Similarly, the user did not want to view any more content. One run was acceptable. Therefore, an electronic ticket including execution range information that defines an allowable range of the one-time execution of the content is transmitted to an acquaintance, so that the acquaintance can view the content using the electronic ticket. In the present embodiment, as in the content management system according to claim 1, execution range information for executing one or more contents whose execution is restricted within a predetermined allowable range is generated and executed. A content distribution server for transmitting an electronic ticket including range information, receiving the electronic ticket, executing the content within an allowable range specified by execution range information included in the electronic ticket, and transmitting the electronic ticket. Is a content management system including a content management device capable of performing the following.
[0015]
(Configuration of Embodiment 1)
[0016]
FIG. 2 is a diagram illustrating an example of a functional block according to the present embodiment. The configuration of the present embodiment will be described with reference to FIG.
[0017]
As shown in the figure, the present embodiment is a content management system including a content distribution server 200 and a content management device 210. The content distribution server 200 includes an execution range information generation unit 201, a transmission unit 202, The content management device 210 is a content management system including an electronic ticket reception unit 211, a content execution unit 212, and an electronic ticket transmission unit 213.
[0018]
(Content distribution server)
[0019]
The “execution range information generation unit 201” generates execution range information for executing one or more contents whose execution is restricted within a predetermined allowable range.
[0020]
The “execution range information” is information for executing one or more contents whose execution is restricted within a predetermined allowable range, as described above. “Execution is restricted” means that execution cannot be performed unless execution is permitted. For example, it means that the target content is encrypted or the like. Further, “one or two or more” contents are targeted, and the contents may be of the same type or different types. The term “content” refers to any one or more of video, sound, characters, computer programs, and the like. Games. The “predetermined allowable range” means a range based on one or both of the period and the number of times. However, the present invention is not necessarily limited to this, and any type of content may be used as long as execution of the content can be restricted.
[0021]
FIG. 3 is a diagram showing an example of the execution range information. In the figure, the “range in which the content can be executed” indicated by the execution range information is indicated by a numeral. In the same figure, the conditions necessary for executing the content whose execution is permitted within a predetermined range based on the execution range information are similarly indicated by numerals. The number indicating the condition for executing the movie content A once is “5”, the number indicating the condition for executing the game content B once is “3”, and the music content C is executed once. Let us consider a case in which the number indicating the condition of “2” is “2” and the number in the range in which the execution of the content indicated by the execution range information is permitted is “10”. In the execution pattern 1, the contents A, B, and C can be executed once. In the execution pattern 2, only the content A can be executed twice. In the execution pattern 3, only the content B can be executed three times. In the execution pattern 4, only the content C can be executed five times.
[0022]
The “transmission unit 202” transmits an electronic ticket including the execution range information generated by the execution range information generation unit.
[0023]
The “electronic ticket” refers to an electronic medium that includes the execution range information and can be transmitted and received between the content distribution server and the content management device, and between the content management device and the content management device.
[0024]
The above is the configuration of the content distribution server configuring the content management system of the present embodiment. With this configuration, it is possible to transmit only an electronic ticket including execution range information for executing the content within a predetermined allowable range separately from the content itself.
[0025]
(Content management device)
[0026]
The “electronic ticket receiving unit 211” receives the electronic ticket. Such an electronic ticket may be transmitted from the transmission unit 202 of the content distribution server 200, or may be transmitted from an electronic ticket transmission unit 213 of the content management device 210 described later.
[0027]
The “content executing unit 212” executes the content within an allowable range defined by the execution range information included in the electronic ticket received by the electronic ticket receiving unit. Such content is not shown or may be transmitted from the content distribution server and received by the content management device, or may be read from an electronic recording medium such as a DVD by the content management device. Is also good.
[0028]
The “electronic ticket information transmitting unit 213” transmits the electronic ticket. When there are a plurality of content management devices that constitute the content management system of the present embodiment, the electronic ticket can be distributed by transmitting and receiving the electronic ticket between the content management devices.
[0029]
The above is the configuration of the content management apparatus that configures the content management system according to the present embodiment. With this configuration, separately from the content itself, by receiving only the electronic ticket, the content can be executed within a predetermined allowable range defined by execution range information included in the electronic ticket. By transmitting the content to the content management device of another person, the content can be executed by another person.
[0030]

Further, the electronic ticket transmitted in step S0402 is received (electronic ticket receiving step S0403). Further, the content is executed within the allowable range defined by the execution range information included in the electronic ticket received in step S0403 (content execution step S0404). Finally, if the content is not executed in the entire allowable range defined by the execution range information included in the electronic ticket in step S0404, the electronic ticket including the execution range information specifying the remaining allowable range is transmitted. Yes (second electronic ticket transmission step S0405).
[0036]
(Brief description of the effects of the first embodiment)
[0037]
By using the content management system of the present embodiment, it is possible to distribute the right to execute the content by removing the restriction from the content whose execution is restricted, in the form of an electronic ticket. For those who receive the electronic ticket and execute the content, the executable content is not limited to one, so the content is executed in the entire allowable range specified by the execution range information included in the electronic ticket. If not, the electronic ticket can be used for other contents. When the electronic ticket is not used for executing the content by itself, the electronic ticket is transmitted to the content management device of another person, so that the content management device can be executed by another person.
