Description

  The present invention relates to a technique for providing audiovisual content.

  The playback device is loaded with a recording medium such as a DVD (Digital Versatile Disc) in which content data indicating audiovisual content including sound and video is recorded, and the content data is read from the loaded recording medium. Viewing audio-visual content is widely performed by playing back audio-visual content. In recent years, content data indicating high-quality audio-visual content recorded on a large-capacity recording medium such as BD (Blu-ray (registered trademark) Disc) has been widely used.

  On the other hand, the content data recorded in the data recording device arranged in the network is sequentially transferred to the playback device by so-called streaming technology, and the audiovisual content indicated by the transferred content data is played back on the playback device, Viewing audiovisual content is also widely performed. In particular, with the spread of the Internet, viewing of audiovisual content by streaming content data stored in a server device connected to the Internet is being widely used.

  In addition, by using both content data recorded on a recording medium and content data recorded on a recording device arranged in a network, a technology for providing audio-visual content that takes advantage of both merits is proposed. ing. For example, in Patent Document 1, a content is recorded according to content data recorded on a recording medium, and when an insertion condition recorded on the recording medium is satisfied, a server device connected to the Internet is used. There has been proposed a technique for reproducing content in accordance with the acquired content data of the inserted content.

  According to the technology proposed in Patent Document 1, for example, before the main content such as a movie is reproduced according to the content data recorded on the recording medium, the reproduction of the main content is stopped and acquired from the server device. Inserted content such as advertisement video is reproduced in accordance with the content data thus obtained. Since the administrator of the server device can easily replace the content data recorded in the server device, the main content viewer can view the desired inserted content at that time.

JP 2005-252576 A

  Hereinafter, the recording medium on which the content data is recorded is referred to as “content package”, and the content data recorded on the content medium is referred to as “package content”. Further, content data provided to the playback device via a network such as the Internet is referred to as “online content”.

  Advertisers who want to add advertising video tend to appear in content packages that can be sold in large numbers. This is because a high advertising effect can be expected for the production cost of the advertising video. Accordingly, audiovisual content creators, content package sellers, and the like can obtain profits from advertising fees paid by advertisers for the addition of advertisement video in addition to profits from sales of content packages.

  On the other hand, there is a problem that advertising revenues cannot be expected in content packages that cannot be expected to be sold as many as so-called indie works, because it is difficult for advertisers who want to add advertisement video.

  In view of the above-described circumstances, the present invention facilitates adding content such as advertisement video to main content that is played back according to the package content recorded in the content package, regardless of the number of content packages sold. It aims at providing the means for.

In order to achieve the above object, the present invention provides:

DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments that are specific examples of the present invention will be described with reference to the drawings.

[1.1. Constitution]
FIG. 1 is a diagram showing an overall configuration of a content providing system 1 according to an embodiment of the present invention. The content providing system 1 includes a creator terminal 11 used by a content package creator to generate a content package, a content package 12 generated by the creator terminal 11, a package content read from the content package 12, and the Internet 16. The player 13 that reproduces audiovisual content according to the online content received from the content server 14, the content server 14 that transmits online content to the player 13, the content package 12, and the online content stored in the content server 14 The management server group 15 which is a server apparatus group for performing an association and managing is provided.

  The management server group 15 includes a ticket management server 151 that manages a “ticket” (to be described later) used to associate the content package 12 with online content, and URI (Uniform Resource Identifier) of the online content as identification data included in the ticket. And a map management server 152 for converting to

  In FIG. 1, only one producer terminal 11, content package 12, and player 13 are shown for convenience, but generally these numbers are numerous and can be arbitrarily changed. Similarly, in FIG. 1, three content servers 14 are shown, but this number is arbitrarily changed.

  The producer terminal 11 includes a communication unit that performs data communication with another device via the Internet 16 and a writing unit that writes data to a recording medium on which data is not written in a state where rewriting is not permitted. It is a general computer provided, and edits package contents according to the operation of the producer by executing processing according to a so-called authoring program. Furthermore, the creator terminal 11 generates various data necessary for playing online content using a ticket by executing processing according to the program according to the present embodiment. Then, the producer terminal 11 generates the content package 12 by writing the package content generated by editing and various data required for playing the online content in a state where rewriting is not permitted on the recording medium.

  FIG. 2 is an image diagram of data recorded in the content package 12 generated in the producer terminal 11. In the content package 12, a content ID for identifying the content package 12 or the main content recorded in the content package 12 is first recorded. A common content ID may be used for a plurality of content packages 12 that record the same main content, or different content IDs may be used in a state where they are a group of content packages 12 that record the same main content. May be.

  Subsequently, main content is recorded in the content package 12. Furthermore, one or more tickets are recorded in the content package 12. The creator can place the ticket at an arbitrary timing within the period before and after the reproduction of the main content, so that the online content can be reproduced.

  At that time, if the ticket is arranged for the inserted content, after the main content playback is suspended or stopped, the online content identified by the ticket is played back, and after the online content playback is completed, it is suspended or stopped. The main content playback is started or resumed. On the other hand, if a ticket is arranged for overlay content, the online content identified by the ticket is reproduced in parallel with the reproduction of the main content without affecting the reproduction of the main content.

  In FIG. 2, the display related to the main content, the inserted content, and the overlay content is a display on the time axis indicating the positive time in the right direction. That is, the position in the left-right direction where the ticket is arranged indicates the start timing of the online content reproduction identified by the ticket.

  Tickets can also be placed for event-driven content. In that case, the start timing of online content playback is independent of the time axis. For example, an event generated by a viewer's operation such as a click on a predetermined button displayed on a display connected to the player 13 or an automatic operation at the creator terminal 11 such that the current time is 12:00. By placing tickets in association with events that are generated automatically, online content playback is triggered by the occurrence of those events.

  The example shown in FIG. 2 is an example in which content with low interactivity such as a movie is used as the main content, but a game or the like in which the content to be reproduced changes according to the operation of the viewer (user) is the main content. The main content itself can be event-driven content.

  Further, when placing a ticket, the creator sets the display position of the online content identified by the ticket, whether or not to allow the viewer to skip playback during playback of the online content, and the like. be able to.

  In addition, the above-described ticket placement operation is performed by graphically moving and placing an object image indicating a ticket displayed on the display in the creator terminal 11 by drag and drop, and then selecting a display position from a menu list as necessary. It can be performed by a simple operation such as

  The ticket according to the present embodiment is a module including a ticket number, which is identification data for identifying online content, and instruction data for instructing processing required for reproducing the online content identified by the ticket number. The ticket is handled as an object in the authoring program executed in the creator terminal 11, and can be added to the content package by a simple operation of the creator as described above.

The instruction data included in the ticket is data that instructs the player 13 to perform the following processing, for example.
(1) Processing for transmitting the content ID to the map management server 152.
(2) Processing for transmitting a ticket number to the map management server 152.
(3) Processing for receiving a URI transmitted from the map management server 152 as a response to the transmission of the ticket number.
(4) Processing for sending the received URI to the Internet 16.
(5) Processing for receiving online content transmitted from any of the content servers 14 as a response to the transmitted URI.
(6) A process of continuously determining whether or not the conditions for starting playback of the received online content are satisfied at sufficiently short time intervals.
(7) Processing for starting reproduction of audiovisual content according to online content when it is determined that the condition for starting reproduction is satisfied.
(8) A process of transmitting start notification data indicating this to the map management server 152 when playback of audiovisual content in accordance with online content has started normally.
(9) A process of transmitting start failure notification data indicating this to the map management server 152 when the reproduction of the audiovisual content according to the online content cannot be started normally.
(10) A process of transmitting, to the map management server 152, end notification data indicating that when reproduction of the audiovisual content according to the online content is ended.
(11) A process of transmitting termination failure notification data indicating that to the map management server 152 when the reproduction of the audiovisual content according to the online content cannot be terminated normally.

  In order to perform the processes (1), (2) and (8) to (11), the ticket includes the address of the map management server 152 on the Internet 16.

  As described above, when an object including the ticket number and instruction data is added as data to be recorded in the content package 12 during authoring in the creator terminal 11, an instance of the object is generated and the creator's operation is performed. Accordingly, condition data indicating a condition for starting the reproduction of the online content identified by the ticket number is set as a parameter in the instance. Note that the conditions indicated by the condition data are, for example, that a predetermined time with reference to the time axis in the reproduction of the main content has arrived, or that a predetermined button is clicked by the viewer.

  The player 13 includes a drive which is a reading means for reading data. When a content package is loaded in the drive, the player 13 reproduces audiovisual content according to the content data recorded in the loaded content package, and for example, a BD player As described above, this is a general playback device having a function of executing data communication with another device, determination processing, and the like via the Internet 16 in accordance with a program recorded in the loaded content package.

  In the present application, the term “playback” is not limited to the process of generating information that can be directly perceived by the viewer as an image or sound according to the content data, but generates data that can generate an image or sound by a simple conversion process. In addition, it is used as a word indicating a broad concept including processing of outputting generated data to a display or a speaker. Therefore, the player 13 may be a device with a built-in display and speaker, or an analog signal or a digital signal indicating an image or sound may be sent to those devices connected with a signal cable or the like without having a built-in display or speaker. An output device may be used.

  The content server 14 is a general content server device that stores a plurality of online contents and transmits the stored online content to a requesting device in response to a request from another device via the Internet 16. Note that the method in which the content server 14 transmits online content is assumed to be progressive download.

  The ticket management server 151 is a server device that manages data relating to each ticket used in the content providing system 1. The ticket management server 151 is realized by causing a general computer having a function of performing data communication with other devices via the Internet 16 to execute processing according to the program according to the present embodiment.

  FIG. 3 is a diagram schematically showing a configuration of a ticket DB (Database) stored in the ticket management server 151. The ticket DB is a collection of records relating to each of all tickets. Each record has the following fields.

Ticket number: A ticket number is identified and converted into a URI in the map management server 152, and a ticket number used for identifying online content is stored.
Content ID: A content ID for identifying the content package 12 in which the ticket is to be recorded is stored.
Owner name: Stores text data indicating the name or name of an owner who is a person or group who can give an arbitrary person the authority to assign online content to a ticket.
Owner public key: Stores text data indicating the file name of the public key uniquely assigned to the owner. The public key file stored in this field is stored in the ticket management server 151.

User name: Stores text data indicating the name or name of a user who is a person or group who is given the authority to assign online content to the ticket from the owner. The default user name is the owner name.
Expiration date: text data indicating the permitted expiration date for the user to use the ticket is stored. If the user is the owner, this time limit is indefinite.
User public key: Stores text data indicating the file name of the public key uniquely assigned to the user. The public key file stored in this field is stored in the ticket management server 151.

URI: The URI of the online content assigned to the ticket is stored. It should be noted that empty data is stored in this field when no online content is assigned to the ticket.
Time required for reproduction: Text data indicating the time required for reproducing the online content assigned to the ticket is stored.

Number of content ID mismatches: A URI inquiry corresponding to a ticket number was received within a predetermined period in the past (for example, the period from the beginning of the month to the present), but the content ID did not correspond to the ticket number. A number indicating the number of times the response to the inquiry is stopped is stored.
Number of start failures: In any past period (for example, the period from the beginning of the month to the present), the online content assigned to the ticket number is attempted to be played by any player 13, but online due to some error Stores a number indicating the number of times content playback could not be started.

Abnormal number of times of end: In some past period (for example, the period from the beginning of the month to the present), the online content assigned to the ticket number has been normally started in any of the players 13, but some error has occurred. Thus, a number indicating the number of times the online content has not been reproduced until the end is stored.
Normal playback count: The number of times that playback of the online content assigned to the ticket number is normally started and ended in any player 13 within a predetermined period in the past (for example, the period from the beginning of the month to the present). The number to be stored is stored.

  The map management server 152 is a server device that receives a ticket number from the player 13 in the content providing system 1 and transmits a URI corresponding to the received ticket number to the player 13 that transmitted the ticket number. The map management server 152 is realized by causing a general computer having a function of performing data communication with other devices via the Internet 16 to execute processing according to the program according to the present embodiment.

  The map management server 152 stores a subset of the ticket DB (see FIG. 3) stored in the ticket management server 151 in order to fulfill the above role. FIG. 4 is a diagram schematically showing a configuration of a subset of the ticket DB stored in the map management server 152. As shown in FIG. 4, the ticket DB subset stored in the map management server 152 includes a ticket number, a content ID, a URI, and a reproduction requirement among the fields of the ticket DB stored in the ticket management server 151. Only time is included.

  The map management server 152 periodically acquires the latest ticket number, content ID and URI included in the ticket DB from the ticket management server 151. The acquisition method is not particularly limited, and for example, a method in which the ticket management server 151 unilaterally transmits the latest data to the map management server 152 may be employed, or the map management server 152 may A method may be employed in which a request is made and the ticket management server 151 transmits the latest data to the map management server 152 in response to the request.

  Alternatively, a method may be employed in which only updated data is unilaterally transmitted from the ticket management server 151 to the map management server 152 at irregular timings when the data is updated in the ticket management server 151. For example, the ticket management server 151 periodically checks whether there is an expired ticket indicated in the “expiration date” of the ticket DB (see FIG. 3), and for the record of the expired ticket, the user Rewrite data about with default owner information. A method may be employed in which the ticket management server 151 unilaterally transmits the latest data to the map management server 152 at that timing.

[1.2. Operation]
Next, the operation of the content providing system 1 will be described. FIG. 5 is a flowchart showing an operation performed in the content providing system 1 when the viewer loads the content package 12 in the player 13 and views the audiovisual content. However, the operation performed on the player 13 for reproducing the main content is the same as the normal operation, and thus the operation is omitted in FIG.

  First, when the viewer loads the content package 12 into the player 13, the player 13 automatically reads FPP (First Play Program Chain) and displays, for example, an initial screen according to the read FPP. After that, for example, when the viewer clicks the button “play main content” arranged on the initial screen (or selects with the cross key and presses the “decision” button), the player 13 responds to the operation with the main content. Start playback.

  The FPP of the content package 12 includes a code that instructs execution of processing according to instruction data included in all tickets recorded in the content package 12. According to the code, the player 13 first reads out the content ID, the ticket numbers of all the tickets, and the condition data from the content package 12 (step S101).

  The player 13 transmits the read content ID and ticket number to the map management server 152 in accordance with the address included in the ticket (step S102).

  The map management server 152 searches the ticket DB for a record including the ticket number received in step S102, and determines whether or not the content ID included in the searched record matches the content ID received in step S102 ( Step S103). If there are a plurality of ticket numbers received in step S102, the process in step S103 is performed for each of the plurality of ticket numbers.

  If it is determined in step S103 that the content IDs do not match (step S103; No), the map management server 152 transmits an error notification including the ticket number corresponding to the mismatch to the player 13 (step S104). The player 13 that has received the error notification ends the series of processes without performing the process described below for the online content related to the ticket number. This is because the ticket is used illegally.

  On the other hand, if it is determined in step S103 that the content IDs match (step S103; Yes), the map management server 152 transmits the URI included in the record searched in step S103 to the player 13 (step S105).

  The player 13 sends the URI received in step S105 to the Internet 16 (step S106). The URI is a combination of a URL (Uniform Resource Locator) corresponding to an IP (Internet Protocol) address indicating the location of the device on the Internet 16 and a path name for identifying data in the device. Among the URIs sent out from the player 13, URLs are converted into IP addresses in a DNS (Domain Name System) server arranged in the Internet 16, and the content server 14 identified by the IP address obtained by the conversion is used. A URI is sent.

  The content server 14 that has received the URI sent from the player 13 sends the online content identified by the path name included in the received URI to the player 13 (step S107).

  In parallel with the processing of step S102 to step S107, the player 13 determines whether or not the condition indicated by the condition data is satisfied for each of the condition data read in step S101 (step S108). If it is determined that the condition is not satisfied in step S108 (No in step S108), the determination in step S108 is repeated at a sufficiently short time interval.

  On the other hand, when it is determined in step S108 that the condition is satisfied (step S108; Yes), the player 13 starts playing the online content identified by the ticket number corresponding to the condition data that satisfies the condition (step S108; Yes). Step S109).

  However, if the online content transmission in step S107 has not started when it is determined that the condition is satisfied in the determination in step S108, the process in step S109 is suspended until the transmission starts. become. The online content transmitted from the content server 14 after the online content transmission in step S107 is started and before the online content reproduction is started in step S109 is temporarily stored in the player 13 and online. Holds until the start of content playback.

  Subsequently, the player 13 determines whether or not the online content reproduction has started correctly in step S109 (step S110). When it is determined that the online content reproduction has not started correctly (step S110; No), the player 13 transmits start failure notification data to the map management server 152 (step S111). On the other hand, when it is determined that the online content reproduction has started correctly (step S110; Yes), the player 13 transmits start notification data to the map management server 152 (step S112).

  Subsequently, the player 13 determines whether or not the online content has been normally reproduced (step S113). When it is determined that the reproduction of online content has not ended correctly (step S113; No), the player 13 transmits end failure notification data to the map management server 152 (step S114). On the other hand, when it is determined that the reproduction of the online content has been correctly completed (step S113; Yes), the player 13 transmits completion notification data to the map management server 152 (step S115).

  Note that when it is determined that the online content playback did not end correctly, for example, the time required for playback of the online content (described in the header of the online content) has elapsed, for example, twice as long as the online content playback start time. This is a case where the online content reproduction has not ended even after.

  The map management server 152 determines the status relating to the online content reproduction based on the determination result in step S103 and the notification data received from the player 13 in step S111, step S112, step S114 and step S115 (step S116). The status data indicating the determination result is transmitted to the ticket management server 151 together with the ticket number corresponding to the online content (step S117).

The status data transmitted from the map management server 152 to the ticket management server 151 in step S117 is, for example, as follows.
If it is determined in step S103 that the content IDs do not match, “content ID mismatch”.
If start failure notification data is received in step S111, “start failure”.
If the start notification data is received in step S112 and the end failure notification data is received in step S114, "abnormal end".
When the start notification data is received in step S112 and the end notification data is received in step S115, “normal reproduction”.
If the start notification data is received in step S112, and then the end failure notification data and the end notification data cannot be received before, for example, three times the time required for playback of the online content (see FIG. 4) has elapsed, "Abnormal termination".

  When the ticket management server 151 receives the status data together with the ticket number in step S117, the ticket management server 151 searches the ticket DB (see FIG. 3) for a record including the received ticket number, and the fields “content ID mismatch count”, “ Of the "start failure count", "abnormal end count", and "normal playback count", 1 is added to the numerical value stored in the field corresponding to the content of the status data to update the data (step S118). For example, if the status data is “content ID mismatch”, the corresponding field is “content ID mismatch count”. Others are the same.

  The above is a case where the content package 12 is loaded in the player 13, and the online content is transmitted from the content server 14 to the player 13 and reproduced in the player 13 in parallel with the reproduction of the main content recorded in the content package 12. This is an operation of the content providing system 1.

  As described above, according to the content providing system 1, the ticket number included in the ticket recorded in the content package 12 is converted into a URI in the map management server 152, and the URL included in the URI obtained by the conversion is used. The online content identified by the path name included in the URI is transmitted from the identified content server 14 to the player 13.

  Therefore, by changing the correspondence between the ticket number and the URI stored in the ticket management server 151 and the map management server 152, the online content that is played when a certain content package 12 is loaded into the player 13 is changed. Is easily possible.

  By the way, as described above, the ticket recorded in the content package 12 in the content providing system 1 is a module that is handled as an object during authoring in the creator terminal 11. Therefore, it is possible to sell this module as a single unit or bundled with an authoring program.

  Therefore, for example, when a ticket including the same ticket number is recorded and sold (or expected to be sold) in a certain number or more of content packages 12, the advertiser wants to purchase the right to use the ticket. If thought, the owner of the ticket can get the price while giving the advertiser the right to use the ticket.

  As described above, according to the content providing system 1, it is possible to attach an advertiser to a content package without being bound by the number of sales of each content package and without being in time for the production timing of the content package.

  As already described, the ticket used at the time of authoring in the creator terminal 11 is an object including a ticket number and instruction data. The administrator of the content providing system 1, that is, the administrator of the management server group 15 can generate a ticket by causing the ticket management server 151 to execute processing according to the application program according to the present embodiment, for example. .

  Further, for example, the creator causes the creator terminal 11 to execute processing in accordance with the application program according to the present embodiment, whereby new registration or change registration of the URI of the online content reproduced by the ticket is registered in the ticket management server 151. It can be done easily.

  Furthermore, the creator can transfer or lend the authority as the owner or user of the ticket he owns to another person. Even in this case, the creator can easily change the registered contents to the ticket management server 151 by using the producer terminal 11, for example.

  In addition, since it is a user who can register or change a URI, for example, if the creator who was the original ticket owner and the user changed the user, a new URI registration is possible. Alternatively, change registration is possible not for the creator but for the new user.

  Hereinafter, the operation of the content providing system 1 relating to these ticket managements will be described. First, FIG. 6 is a flowchart showing the operation of the content providing system 1 when the ticket management server 151 issues a new ticket to the creator terminal 11 and authoring is performed at the creator terminal 11 using the ticket. is there.

  When the administrator of the content providing system 1 receives a purchase order for a ticket from the producer, the manager of the content providing system 1 operates the producer terminal 11 to instruct a new ticket issue. At that time, the administrator inputs a mail address of an e-mail that can be received at the producer terminal 11 to the producer terminal 11. In response to the instruction, the producer terminal 11 first generates an unused ticket number in the field “ticket number” of the ticket DB, and creates a new record in the ticket DB (see FIG. 3). The generated ticket number is registered in “number” (step S201).

  Subsequently, the creator terminal 11 sets the ticket number generated in step S201 for the template object for which the ticket number has not yet been set (step S202). The creator terminal 11 sends the object with the ticket number set, that is, the ticket attached to an e-mail addressed to the e-mail address input by the administrator, for example (step S203). At that time, a utility program for instructing the creator terminal 11 to process the producer terminal 11 described below is also transmitted. Note that the ticket transmitted to the creator terminal 11 in step S203 has been deactivated and cannot be used yet for authoring.

  The producer terminal 11 installs the utility program received in step S203 on its own device (step S204). According to the utility program, the producer terminal 11 displays a screen that prompts the producer to register the owner name and the creator's public key. According to the display, when the producer inputs his / her name as the owner name into the producer terminal 11 and designates his / her public key file, and performs a predetermined operation such as clicking the “Send” button, In response to the operation, the producer terminal 11 transmits the input owner name and the designated public key file together with the ticket number to the ticket management server 151 (step S205).

  In the following, when the producer terminal 11 transmits data to the ticket management server 151, a communication connection is established between the producer terminal 11 and the ticket management server 151 according to the utility program, and data via the communication connection is established. Communication takes place.

  The ticket management server 151 searches the ticket DB (see FIG. 3) for a record including the ticket number received in step S205, and stores the received owner names in the fields “owner name” and “user” of the searched record. Register the received public key file name in the fields “owner public key” and “user public key”, “indefinite period” in the field “expiration date”, and store the received public key in its own storage (Step S206).

  Subsequently, the ticket management server 151 transmits the ticket activation key to the producer terminal 11 together with the ticket number of the record that has been registered in step S206 (step S207). The creator terminal 11 activates the deactivated ticket using the received activation key (step S208). As a result, the ticket can be used for authoring at the creator terminal 11.

  In response to the operation of the creator, the creator terminal 11 authors data to be recorded in the content package 12 (step S209).

  When the authoring is completed, the creator terminal 11 burns the data generated by the authoring on a so-called blank medium in accordance with the operation of the creator, and creates a temporary content package (step S210).

  No content ID is recorded in the temporary content package, and the creator receives the provision of the content ID by mailing the temporary content package to a predetermined organization and through examination. Thereafter, upon receiving the content ID, the data generated in step S209 with the content ID added is written on a blank disc by a press or the like, and the formal content package 12 is mass-produced.

  When the author loads the official content package 12 prepared as described above into the creator terminal 11 and performs a predetermined operation, the creator terminal 11 follows the utility program and the content ID and all the content IDs from the loaded content package 12. The digital signature using the creator's private key is added to the read content ID (step S211), and the content ID with the digital signature is transmitted to the ticket management server 151 together with the ticket number (step S211). S212).

  The ticket management server 151 searches the ticket DB (see FIG. 3) for a record including the received ticket number, and verifies the electronic signature added to the received content ID using the owner public key indicated in the searched record. Is performed (step S213). If this verification fails (step S213; No), the ticket management server 151 transmits an error notification to the producer terminal 11 (step S214), and the series of processing ends.

  On the other hand, if the verification in step S213 is successful (step S213; Yes), the ticket management server 151 registers the content ID in the retrieved record (step S215), and transmits a success notification to the producer terminal 11 (step S216). ). As a result, preparation for production and sale of the content package 12 is completed.

  FIG. 7 is a flowchart showing the operation of the content providing system 1 in the ticket user change procedure. The user can be changed by the authority of the owner. Therefore, when the producer who is the owner operates the producer terminal 11, for example, the change procedure is performed.

  The creator operates the creator terminal 11 and inputs the ticket number of the ticket to be changed, the user name of the new user, the public key of the new user, and the expiration date of the new user (step). S301). When the producer terminal 11 completes the input in step S301, it adds an electronic signature to the data other than the entered ticket number using the secret key of the producer (step S302). The producer terminal 11 transmits the ticket number and the public key of the new user with the electronic signature added to the ticket management server 151 (step S303).

  The ticket management server 151 searches the ticket DB (see FIG. 3) for the record including the ticket number received in step S303, and uses the owner public key indicated in the searched record as the public key of the new user received. The added electronic signature is verified (step S304).

  If the verification in step S304 fails (step S304; No), the ticket management server 151 transmits an error notification to the producer terminal 11 (step S305), and the series of processing ends.

  On the other hand, if the verification in step S304 is successful (step S304; Yes), the ticket management server 151 receives the corresponding data received in the fields “user name”, “user public key”, and “expiration date” of the retrieved record. And the received public key are stored in the storage means (step S306), and a success notification is transmitted to the producer terminal 11 (step S307). Thereby, the change of the user is completed.

  FIG. 8 is a flowchart showing the operation of the content providing system 1 in the registration procedure of the URI of the online content to be reproduced by the ticket. In the following description using FIG. 8, it is assumed that the current ticket user is a producer and the producer terminal 11 used by the producer is used in the URI registration procedure. In the case of being handed over from the creator to a new user, the terminal device used by the new user performs the following processing instead of the creator terminal 11.

  First, when the producer receives a notification of the URI of the online content of the advertisement video from, for example, an advertising agency or advertiser, the producer operates the producer terminal 11 and inputs the ticket number and URI of the ticket for which the URI is to be registered. (Step S401). When the creator terminal 11 completes the input in step S401, it adds an electronic signature to the input URI using the secret key of the producer (step S402). The producer terminal 11 transmits the ticket number and the URI with the electronic signature added to the ticket management server 151 (step S403).

  The ticket management server 151 searches the ticket DB (see FIG. 3) for a record including the ticket number received in step S403, and verifies the electronic signature added to the URI using the user public key indicated in the searched record. Is performed (step S404).

  If the verification in step S404 fails (step S404; No), the ticket management server 151 transmits an error notification to the producer terminal 11 (step S405), and the series of processing ends.

  On the other hand, if the verification in step S404 is successful (step S404; Yes), the ticket management server 151 sends a URI to the Internet 16 (step S406). As a response to sending the URI in step S406, the content server 14 transmits the online content to the ticket management server 151 (step S407).

  The ticket management server 151 determines whether or not the online content has been successfully received in step S407 (step S408). For example, when online content cannot be received because the online content corresponding to the URI is not stored in the Internet 16 and it is determined in step S408 that reception of online content has failed (step S408; No), The ticket management server 151 transmits an error notification to the producer terminal 11 (step S409), and ends a series of processing.

  On the other hand, if it is determined in step S408 that the online content has been successfully received (step S408; Yes), the ticket management server 151 searches the URI and the time required for reproduction described in the header of the online content in step S404. Each field is registered in the fields “URI” and “required playback time” of the record (step S410).

  Subsequently, the ticket management server 151 transmits a success notification to the producer terminal 11 (step S411). This completes the registration of the URI.

  FIG. 9 is a flowchart showing the operation of the content providing system 1 in the procedure for changing the ticket owner. The owner can be changed depending on the authority of the current owner. Therefore, the producer who is the current owner operates the producer terminal 11 to perform the change procedure.

  The producer operates the producer terminal 11 and inputs the ticket number of the ticket whose owner is to be changed, the user name of the new owner, the public key of the new owner, and the necessity of resetting the current user. (Step S501). When the creator terminal 11 completes the input in step S501, it adds an electronic signature to the data other than the entered ticket number using the secret key of the producer (step S502). The producer terminal 11 transmits the ticket number and the public key of the new owner with the electronic signature added to the ticket management server 151 (step S503).

  The ticket management server 151 searches the ticket DB (see FIG. 3) for a record including the ticket number received in step S503, and uses the owner public key indicated in the retrieved record as a new user public key or the like. The added electronic signature is verified (step S504).

  When the verification in step S504 fails (step S504; No), the ticket management server 151 transmits an error notification to the producer terminal 11 (step S505), and the series of processing ends.

  On the other hand, if the verification in step S504 is successful (step S504; Yes), the ticket management server 151 registers and receives the received corresponding data in the fields “owner name” and “owner public key” of the retrieved record. The public key is stored in the storage means. If the data received in step S503 includes data for instructing resetting of the current user, the “owner name” and the “user name” after the change to the fields “user name” and “user public key” and The same data as the “owner public key” is registered, and “indefinite” is registered in the field “expiration date” (step S506).

  Thereafter, the ticket management server 151 transmits a success notification to the producer terminal 11 (step S507). As a result, the owner change is completed.

  As described above, according to the content providing system 1, all of the registration procedures associated with the sale, lending, transfer, and change of online content to be reproduced by a ticket can be performed by operation via the Internet 16. , Fluidization in the ticket market is promoted.

Further, the ticket management server 151 and the map management server 152 may be realized by a plurality of server device groups operating in cooperation with each other.

  In the above-described embodiment, after the content package 12 is loaded into the player 13, download of online content corresponding to all ticket numbers recorded in the content package 12 from the content server 14 is started. However, the timing of downloading each online content can be arbitrarily changed. For example, the URI may be sent to the Internet 16 when the condition indicated by the condition data is satisfied, and the download may be started. In addition, for online content whose playback start timing can be predicted in advance, download is started at a timing that is a time set in advance by the creator as a ticket parameter from the predicted playback start timing. Also good.

  In the above-described embodiment, the ticket management server 151 issues a new ticket. However, for example, the ticket may be issued by another device such as a terminal device used by the administrator. In this case, for example, the administrator's terminal device may receive a notification of a new ticket number from the ticket management server 151, or manually input the new ticket number secured in the ticket management server 151 to the administrator's terminal device. It may be.

  In the above-described embodiment, the producer terminal 11 is used for URI registration or the like. However, for example, another terminal device used by the producer may be used.

  Many of the processes described in the above-described embodiments have the same result even if the temporal order is changed. All such changes in the order are modifications of the embodiment described above.

  In the above-described embodiment, progressive download is adopted as a method for transmitting online content from the content server 14 to the player 13, but other methods such as real streaming and normal download may be adopted. Good.

  In the embodiment described above, the creator terminal 11, the ticket management server 151, and the map management server 152 are realized by causing a general computer to execute processing according to an application program. These may be realized.

  In the above-described embodiment, the content package 12 has been described on the assumption that data is written on a read-only medium such as a BD.
