Description

  The present invention relates to a content distribution system and a content distribution method for transmitting / receiving predetermined content data distributed from a content distribution device through a plurality of terminal devices connected to each other via a network such as a so-called peer-to-peer system. About.

  Today, many personal computer devices existing on a network are connected to each other, and information is directly transmitted and received between the personal computer devices, thereby sharing information resources such as files and computing power. A network system called “Peer to Peer (P2P)” is known.

  Japanese Laid-Open Patent Publication No. 2005-85146 (Patent Document 1) discloses a content distribution system for efficiently distributing video content using this peer-to-peer network system.

  In the case of this content distribution system, a terminal device (client) that desires distribution of video content multicasts a distribution request for the desired video content via a network such as the Internet or a LAN. This distribution request is received by the video distribution server and other terminal devices connected to the network.

  Upon receiving this distribution request, the video distribution server returns a response indicating that video distribution is possible to the terminal device that has made the distribution request. Also, the other terminal device caches the video content requested for distribution in a secondary cache described below, and when the distribution is possible, responds to the terminal device that has made the distribution request. I do.

  The terminal device that has made the distribution request compares the responses sent back from the video distribution server and other terminal devices with the reception time, and the device with the earliest reception time of the response (the video distribution server or the other terminal). Device) is requested to distribute video content. The video distribution server or the other terminal device that has made the distribution request distributes the video content to the terminal device that has made the distribution request via the LAN.

Upon receiving the distributed video content, the terminal device that has made the distribution request first caches the content in the primary cache, sequentially reproduces the cached content on the decoder, and uses the video content as a secondary cache for distribution. To cache. When receiving a distribution request from another terminal device, the video content cached in the secondary cache is distributed to the other terminal device. As a result, video content is efficiently distributed without being affected by the arrangement of devices on the network.

Can do. Therefore, more terminal devices that function as the relay device can be secured, and the system can be stabilized.

  Further, the present invention adds content to the content when the content distribution device distributes the content with a predetermined number of points added and the control means of the terminal device performs viewing control or listening control of the content. The number of points of the current point is added to the number of points stored in the storage means. As a result, the user can accumulate points only by viewing or listening to the distributed content, and thus can facilitate viewing or listening of the content distributed from the content distribution device. Therefore, since more terminal devices can be activated for viewing or listening to the content, the system can be stabilized.

  Also, the present invention provides the terminal device control means for distributing the point exchange content that can be viewed or heard by exchanging for a predetermined number of points to the terminal device via the network. When the viewing control or listening control of the point exchange content is performed, the number of points corresponding to the point exchange content is subtracted from the number of points stored in the storage means. This makes it possible to return profits to the producer of the point exchange content.

  Further, according to the present invention, when an operation command for designating access to an access destination of the CM content being displayed is transmitted from the mobile terminal device to the terminal device, the terminal device adds the access information added to the CM content being displayed. Is returned to the portable terminal device. Then, the mobile terminal device accesses the access destination corresponding to the CM content based on the access information returned from the terminal device.

  Further, according to the present invention, the current position detecting means provided in the portable terminal device detects the current position of the portable terminal device and transmits it to the terminal device. When there are a plurality of access information added to the CM content, the terminal device selects an access destination that is geographically close to the current position of the mobile terminal device received from the mobile terminal device from the plurality of access information. Corresponding access information is selected and returned to the mobile terminal device. The mobile terminal device attempts to access an access destination that is located in a geographically close position of the mobile terminal device by performing access based on the access information.

Thereby, registration of the terminal device 3 to be remotely operated by the mobile phone 6 is completed, and thereafter, the remote operation of the terminal device 3 using the mobile phone 6 becomes possible.

[System operation]
(Normal content distribution operation)
By operating the system having the above configuration, the content distribution method of the present invention can be implemented. That is, as described above, this content distribution system distributes predetermined content in the form of a peer-to-peer network system. Specifically, a user who wishes to distribute content D1 operates peer terminal device 3 to perform peer-to-peer distribution to another terminal device 3 (partner terminal device) that stores the desired content. Request. As a result, the content is distributed from the other terminal device 3 to the terminal device 3 that has made the distribution request, and the content is encrypted with the encryption key.

  For this reason, the user who has received the content makes a distribution request for the decryption key D2 of the content to the billing server device 9 of the business server device 2 through his / her terminal device 3. When this distribution request is made, the accounting server device 9 performs user authentication processing and performs accounting processing for the user who has requested the distribution of the decryption key D2 based on the access information for the accounting server device 9. Do. Then, it accesses the DRM license server device 8 and makes a distribution request for the decryption key D2 to the terminal device 3 of this user. As a result, the decryption key D2 is distributed from the DRM license server device 8 to the terminal device 3 of the user, and the content is decrypted and reproduced in the terminal device 3 based on the decryption key D2.

(CM content distribution)
Next, in the case of such a peer-to-peer network system, it is necessary to keep the terminal device 3 of each user functioning as a relay device (partner) for the content to be distributed for a longer time. For this reason, in the case of the content distribution system, the CM content described below is distributed to each terminal device 3, and the user can receive various services based on the CM content, so that the activation state of the terminal Incentives to maintain

  Specifically, the DRM license server device 8 of the provider server device 2 distributes the CM content to each terminal device 3 at a predetermined timing such as midnight or early morning. When this CM content is received, the control unit 18 of each terminal device 3 stores it in the memory 17. Accordingly, the CM content can be distributed to each terminal device 3 without being noticed by the user at night or while the user is at work. The control unit 18 controls display of the CM content on the monitor device 10 at the following timing.

(CM content display operation based on the screen saver function)
When controlling the storage of the CM content in the memory 17, the control unit 18 of each terminal device 3 starts counting the time that has elapsed since the terminal device 3 is in a non-operation state at the storage timing. When the terminal device 3 detects that a predetermined time has elapsed since the terminal device 3 becomes non-operational after the content can be relayed by the peer-to-peer system, the control unit 18 activates the screen saver function, The CM content stored in 17 is read out and displayed on the monitor device 10. As a result, for example, the CM content is displayed on the monitor device 10 as shown in FIG.

  Next, when the CM content is displayed on the monitor device 10, the display time counting unit 14 shown in FIG. 3 (a) starts counting the display time of the CM content. The display time counting unit 14 stops counting the display time of the CM content at the timing when the control unit 18 detects that the operation of the terminal device 3 is started by the user. Then, this count value is supplied to the control unit 18.

  The control unit 18 refers to the time corresponding point number table 15 based on the display time of the CM content counted by the display time counting unit 14, and the number of points corresponding to the display time counted by the display time counting unit 14 Is read. The number of points is controlled and stored in the memory 17.

  Each terminal device 3 thus displays CM content on the monitor device 10 based on the screen saver function, detects the number of points corresponding to this display time, and stores and controls this in the memory 17. As a result, every time CM content is displayed, the number of points corresponding to the display time is accumulated in the memory 17.

(Point addition / subtraction processing by viewing / listening to predetermined content)
Next, in the case of this content distribution system, the points accumulated in the memory 17 of each terminal device 3 are further added by viewing and listening to the point-added content to which points are added, or a predetermined number of points. Subtraction is performed by viewing and listening to point exchange content that can be viewed and listened to in exchange.

  Specifically, the DRM license server device 8 adds a predetermined number of points to the predetermined content for distribution, and the control unit 18 of each terminal device 3 views the point-added content. When control or listening control is performed, the number of points added to the point-added content is added to the number of points stored in the memory 17. Thereby, the user can increase the number of points stored in the memory 17 only by viewing or listening to the predetermined content.

  On the other hand, the DRM license server device 8 also distributes point exchange content that allows viewing and listening in exchange for a predetermined number of points. When the control unit 18 of each terminal device 3 performs the viewing control or listening control of the point exchange content, the point number stored in the memory 17 indicates the number of points that is a price for viewing or listening to the point exchange content. Subtract from the number. Then, the control unit 18 transmits information indicating the number of points subjected to the subtraction process to the DRM license server device 8.

  The DRM license server device 8 counts the number of points that are transmitted from the control unit 18 of each terminal device 3 and serves as a price for viewing or listening to the point exchange content. The business operator of the business operator server device 2 pays a price corresponding to the number of points counted by the DRM license server device 8 to the producer of the point exchange content. This makes it possible to collect points from each user and return profits to the producer of the point exchange content.

(Provide services based on CM content)
Next, each user can receive various services based on the CM content displayed on the monitor device 10 by remotely operating the terminal device 3 using the mobile phone 6 as a remote controller.

  As an example, when the CM content displayed on the monitor device 10 is CM content for a food and beverage delivery service, the user can select a desired menu and place an order for food and beverage delivery.

  Specifically, in this case, a “menu display button” is displayed on the CM content display screen as shown in FIG. When the user selects a desired menu from a plurality of menus, the user operates the movement operation key 43 of the mobile phone 6 in which RFID registration has been performed as described above. When the movement operation key 43 is operated, the control unit 32 of the mobile phone 6 shown in FIG. 3B sends an operation command corresponding to the operation of the movement operation key 43 through the infrared transmission / reception unit 29. Send to 3. When the terminal device 3 receives this operation command at the infrared transmission / reception unit 13 shown in FIG. 3 (a), the control unit 18 controls to move and display the cursor displayed on the display screen in accordance with the operation command. .

  The user operates the movement operation key 43 to move the cursor on the display screen to the display area of the “menu display button”, and clicks the right key 41 or the left key 42. The control unit 32 of the mobile phone 6 transmits an operation command corresponding to the click operation of the right key 41 or the left key 42 to the terminal device 3 via the infrared transmission / reception unit 29. When the infrared transmission / reception unit 13 receives this operation command, the control unit 18 of the terminal device 3 controls display of various menu display screens as shown in FIG. Then, display control of the “telephone button” which means to place a telephone order on the monitor device 10 is performed.

  The user operates the movement operation key 43 to select a desired menu from various menus displayed on the monitor device 10, and when ordering the selected menu, the user operates the movement operation key 43. Then, the cursor is moved to the “telephone button” displayed on the monitor device 10, and the left key 42 (or the right key 41) serving as the determination key in this case is clicked.

  When the left key 42 is clicked, the control unit 32 of the mobile phone 6 transmits this operation command by infrared as described above. When the control unit 18 of the terminal device 3 receives an operation command indicating that the left key 42 has been clicked from the mobile phone 6 while the cursor is moved and displayed on the “phone button”, the order of the currently selected menu is received. Is transmitted to the mobile phone 6, and a distribution request of “the phone number of the mobile phone 6” and “the current position of the mobile phone 6” is transmitted.

  When receiving the distribution request, the control unit 32 of the mobile phone 6 reads the mobile phone number of the local station stored in the memory 31 and transmits it to the terminal device 3, and the mobile phone detected by the GPS sensor 28. The current position of 6 is transmitted to the terminal device 3.

  In the CM content displayed on the monitor device 10, the location of the advertiser or the advertiser's store, a telephone number, an e-mail address, coupon information, and the like are added as access information. When there are a plurality of stores, the access information for each store is added. This access information is stored in the memory 17 when the terminal device 3 receives the CM content as described above.

  For this reason, when the terminal device 3 receives the current location from the mobile phone 6, the store closest to the current location of the mobile phone 6 is based on the location included in the access information for each store stored in the memory 17. And the telephone number of the nearest store is transmitted to the mobile phone 6.

  In addition, when the terminal device 3 has a coupon added to the menu selected by the user, the “coupon information”, the “mobile phone number” received from the mobile phone 6, and the mobile phone 6 An e-mail indicating “current position” is created and transmitted to the server device 4 in the store. As a result, the electronic mail is transmitted to the server device 4 in the store via the base station 7 and the network 1 shown in FIG.

  On the other hand, the control unit 32 of the mobile phone 6 is closest to the current position of the mobile phone 6 received from the terminal device 3 by controlling communication of the communication circuit 22 in parallel with the operation of the terminal device 3. Call the store's phone number automatically. As a result, a telephone call arrives at the store telephone 5 (fixed telephone or mobile phone) shown in FIG. 1, and the user of the mobile phone 6 has a telephone conversation with the person in charge of the store and orders delivery of a desired menu. However, as described above, the “coupon information”, the “mobile phone number” of the mobile phone 6 and the “current position” of the mobile phone 6 are transmitted to the server device 4 of the store by electronic mail.

  For this reason, the store side can determine whether or not “coupon is applied” based on the “coupon information” described in the e-mail before talking with the user over the phone. The identity of the user can be confirmed based on the “number”, and the address (delivery address) of the orderer can be recognized based on the “current position” of the mobile phone 6. For this reason, the user of the mobile phone 6 simply conveys only the menu for which delivery is desired to the person in charge of the store, and the product of the ordered menu is the user's address (= current position of the mobile phone 6). Will be delivered to.

(Automatic payment)
Next, when the control unit 18 of the terminal device 3 receives an operation command indicating that the “telephone button” displayed on the monitor device 10 has been clicked from the mobile phone 6, the monitor 18 performs monitoring as shown in FIG. The device 10 is controlled to display a payment method selection screen for the product ordered by the user. In the example shown in FIG. 7, the monitor device 10 selects a “cash on delivery” selection button for paying with cash or a cash card when goods arrive and a selection of “electronic money settlement” for payment with electronic money. This is an example in which buttons are displayed.

  When the payment method selection screen is displayed, the user operates the movement operation key 43 of the mobile phone 6 to move the cursor on the display screen, and selects one of the payment methods.

  When “cash on delivery” is selected as the payment method, this information is transmitted from the terminal device 3 to the server device 4 of the store by the electronic mail. Thereby, at the store side, when the product is delivered to the home, the user collects the money with cash or a cash card.

  On the other hand, when “electronic money settlement” is selected as the payment method, the user connects the non-contact IC card 30 provided in his / her mobile phone 6 to the non-contact IC reader / writer unit 19 of the terminal device 3. Close. Thereby, the non-contact IC card 30 provided in the mobile phone 6 is activated by the non-contact IC reader / writer unit 19 provided on the terminal device 3 side, and the control unit 37 of the non-contact IC card 30; The non-contact IC reader / writer unit 19 enters a communication state. Then, the electronic money information corresponding to the price of the product is read from the memory 36 by the control unit 37 of the non-contact IC card 30, and the non-contact IC reader / writer unit 19 of the terminal device 3 is connected via the non-contact IC antenna 35. Sent to.

  The control unit 18 of the terminal device 3 transmits electronic money information corresponding to the price of the product received by the contactless IC reader / writer unit 19 to the billing server device 9 of the business server device 2 via the communication circuit 22. To do. The billing server device 9 transmits this electronic money information as sales information to the server device 4 in the store. Thereby, the automatic settlement of the ordered product is completed.

(Modification 1)
The above example is an example in which a desired menu is selected from the product menu displayed on the terminal device 3 and purchased. Hereinafter, the product barcode or product ID attached to the product or catalog is used as the mobile phone 6. An example of purchasing a desired product or content by reading and transmitting to the terminal device 3 will be described.

  In this case, the user activates the camera unit 27 of the mobile phone 6 and, as shown in FIG. 8 or FIG. 9, the product barcode (1D barcode, 2D barcode, etc.) attached to the product, or at hand The product bar code of the desired product described in the catalog is imaged. When the commodity barcode is captured, the control unit 32 analyzes the captured barcode based on the captured image to form barcode information, and controls the terminal device 3 to perform infrared transmission.

  Further, when the product ID tag is attached to the product at hand, the user activates the RFID reader unit 33 of the mobile phone 6 and reads the product ID from the product ID tag. When the product ID is read, the control unit 32 forms product ID information, and controls the terminal device 3 to perform infrared transmission.

  The terminal device 3 transmits the product barcode or product ID transmitted from the mobile phone 6 to the DRM license server device 8 of the communication carrier server device 2. As shown in FIG. 8, the DRM license server device 8 has a product database 55 (product DB) in which various product information corresponding to each product barcode or each product ID is stored. Product information corresponding to the product barcode or product ID transmitted from the device 3 is read out and returned to the terminal device 3. When receiving the product information, the terminal device 3 displays the product information on the monitor device 10.
