Description

  The present invention relates to a technology for providing a service for distributing content.

  Techniques for distributing information related to various contents such as music and games to terminal devices have been proposed. For example, Patent Document 1 discloses a terminal device that can receive information related to music by extracting identification information of the music from music flowing in a coffee shop or the like.

JP 2007-215198 A

By the way, in a service for distributing content, a service mode that allows an introducer to introduce content to other users is assumed. In this service form, when the incentive for the introducer increases, it is expected that the introduction of the content is more actively performed. Therefore, if the technique described in Patent Document 1 is adopted, the content introducer can easily introduce the content by transmitting the music identification information to the terminal device of another user. However, since the introducer cannot obtain any benefit even if the music identification information is transmitted, it is not sufficient as an incentive to introduce the content.
In view of the above circumstances, it is an object of the present invention to provide a technology that can make content introduction between users more active.

In order to solve the above problems, one aspect of the terminal device according to the present invention is capable of communicating with a privilege management server that manages a privilege given when content is introduced to another user for each identification information of the content introducer. Between the communication unit capable of communicating with the introduction content management server that manages the content to be introduced for each introducer's identification information, the transmission device capable of transmitting the introducer's identification information, and the terminal device In the wireless information communication, a receiving unit that receives the introducer identification information and the introducer identification information received by the receiving unit via the communication unit are associated with the introduction content management server. A content information acquisition unit that acquires information related to content, and a report unit that reports the identification information of the introducer to the privilege management server via the communication unit. . In this aspect, since the identification information of the content introducer is reported to the privilege management server, the incentive to introduce the content is increased, so that the content introduction can be performed more actively. Also, if the introducer's identification information is sent to other users, it is possible to introduce multiple contents. Therefore, compared to the case where contents are sent to other users as in the past, identification of multiple contents is possible. There is an advantage that the trouble of transmitting information is eliminated and the processing load in communication is reduced.
Here, examples of “information related to content” include content identification information, content attribute information, and content itself. “Content attribute information” includes the name of a song and the name of a singer when the content is a song. In addition, examples of the “transmission device” include an introducer's terminal device (for example, a smartphone), a sound emission system in a store, a public facility, and the like. “Wireless information communication” is information communication (wireless communication in a broad sense) realized by using a transmission medium that exists in the space between devices without interposing a wired transmission path. Telecommunications using a transmission medium as a transmission medium (wireless communication in a narrow sense) and acoustic communication using a sound wave propagating between apparatuses (vibration of air) as a transmission medium.

  In the terminal device according to a preferred aspect of the present invention, the receiving unit is configured to collect sound including the introducer identification information, and to identify the introducer from the sound collected by the sound collecting unit. An identification information acquisition unit that acquires information. In this aspect, since the sound representing the introducer's identification information is collected by the sound collection unit (for example, a microphone) and the identification information is acquired from the collected sound, the transmission device and the terminal device are used. Introducer identification information can be received without establishing an individual communication link. In addition, since other terminal devices in the space where the transmission device and the terminal device exist can also pick up sound, users other than the user that the introducer introduces can freely receive the introducer's identification information. In addition, as long as the terminal device has a sound collection unit, there is an advantage that the identification information of the introducer can be received. That is, even when the terminal device does not have a short-range (or non-contact) communication function such as Bluetooth (registered trademark) or FeliCa (registered trademark), the identification information of the introducer can be received. Therefore, introduction of content can be promoted more efficiently.

  In a preferred aspect of the present invention, the content information acquisition unit acquires the attribute information of the content as information related to the content, and the terminal device acquires the attribute information of the content acquired by the content information acquisition unit. A notification unit for notifying the user of the terminal device is further provided. Here, the notification by the “notification unit” includes, for example, displaying the attribute information of the content on the display unit of the terminal device, and notifying the attribute information of the content by sound by the sound emitting unit of the terminal device. . In this aspect, the content information acquisition unit notifies the user of the terminal device of the attribute information of the content. Therefore, the user of the terminal device displays the notified content attribute information by display or sound (or display and sound). It becomes possible to confirm.

  In a preferred aspect of the present invention, when the terminal device acquires the content in response to an instruction from the user referring to the attribute information notified by the notification unit, the reporting unit The identification information is reported to the privilege management server. In this aspect, when the content introduced by the introducer is acquired by the terminal device, the identification information of the introducer is reported to the privilege management server, so that the introduced person actually acquires the content introduced by the introducer. As a condition, it is possible to give a privilege to the introducer. Therefore, there is an advantage that profits are surely returned not only to the content introducer but also to the service provider who distributes the content.

  In addition, one aspect of the program according to the present invention is capable of communicating with a privilege management server that manages a privilege granted when content is introduced to another user for each identification information of the content introducer, and introduces the privilege. Wireless information between the computer and the transmitting device capable of transmitting the introducer's identification information to a computer having a communication unit capable of communicating with the introduction content management server that manages the content for each introducer's identification information In communication, receiving processing for receiving the identification information of the introducer, and content information for acquiring information related to the content associated with the received identification information of the introducer in the introduction content management server via the communication unit An acquisition process and a report process for reporting the introducer's identification information to the privilege management server via the communication unit. Make. Also in this aspect, the same effect as the above terminal device can be obtained. The above program is provided in a form stored in a computer-readable recording medium and installed in the computer, or is provided in a form distributed via a communication network and installed in the computer.

It is a figure which shows an example of the memory content of an introduction content management table. It is a figure which shows an example of the memory content of a privilege management table. It is a sequence chart which shows the operation example of a communication system. It is a block diagram which shows the whole structure of the communication system of 2nd Embodiment of this invention.

<First Embodiment>
FIG. 1 is a block diagram showing the overall configuration of a communication system 100 according to the first embodiment of the present invention. The communication system 100 of 1st Embodiment is provided with the service provision system 20, the content server 30, and the some terminal device 10 (10A, 10B). Each terminal device 10 can communicate with each of the service providing system 20 and the content server 30 via a communication network N (for example, a mobile communication network or the Internet).
The service providing system 20 is a system for providing a content introduction service in which a certain user introduces content to other users. In the following description, music is described as an example of content, but the type of content is not limited to this. For example, a configuration that provides a game, a moving image, or the like as content may be employed. In the content introduction service of this embodiment, it is assumed that user A introduces music to user B. A terminal device 10A in FIG. 1 is a user A terminal device. The terminal device 10B is a user B terminal device.

  The service providing system 20 includes an ID assigning server 20A, an introduction content management server 20B, and a privilege management server 20C. In response to a request from the terminal device 10A, the ID assigning server 20A generates an acoustic signal AS including identification information UIda for uniquely identifying the user A, and transmits the acoustic signal AS to the terminal device 10A. The acoustic signal AS is transmitted to the terminal device 10A as an acoustic file in, for example, a WAV format or an MPE format. A known method can be arbitrarily adopted for generation of the acoustic signal AS (acoustic watermark), but for example, the method disclosed in International Publication No. 2010/016589 is suitable. Specifically, the ID assigning server 20A executes the modulation (spreading modulation) of the identification information UIDa using a spread code and the modulation using a carrier wave of a predetermined frequency in order to identify the identification information UIDa. An acoustic signal AS contained as an acoustic component in the frequency band is generated. The frequency band of the acoustic signal AS is a frequency band in which sound can be emitted and collected by a general acoustic device, and the frequency band of normal sound (voice or musical sound) that the listener listens to (for example, in the audible range) Of about 16 kHz or less) (for example, 18 kHz or more and 20 kHz or less). Therefore, the reproduced sound of the acoustic signal AS including the identification information UIda is hardly perceived by the user.

  The introduction content management server 20B manages music that the user of each terminal device 10 introduces to other users. Specifically, the introductory content management server 20B refers to the introductory content management table TBL1, and stores the identification information of one or more pieces of music stored in association with the identification information UIDa of the user A received from the terminal device 10B. It transmits with respect to the terminal device 10B. The privilege management server 20C manages privileges (points in the present embodiment) that are given to users who have introduced music to other users. Specifically, the privilege management server 20C refers to the privilege management table TBL2, and updates information indicating the privilege stored in association with the identification information UIDA of the user A reported from the terminal device 10B. The introduction content management table TBL1 and the privilege management table TBL2 will be described in detail later.

  The content server 30 (for example, a web server) is a server that provides music to each terminal device 10. The content server 30 according to the first embodiment transmits music attribute information DA to the terminal device 10B in response to a request from the terminal device 10B. Specifically, when the content server 30 receives the music identification information from the terminal device 10B, the content server 30 transmits the music attribute information DA (for example, music name, singer name, music data for viewing, etc.) to the terminal device 10B. To do. Further, the content server 30 transmits the music data DM to the terminal device 10B in response to a request from the terminal device 10B. Specifically, when the user B of the terminal device 10B requests the content server 30 to download a song based on the attribute information DA, the content server 30 transmits the song data DM to the terminal device 10B. The music data DM is data for reproducing the sound of various music such as a song. The format of the music data DM is arbitrary. For example, a file in MP3 (MPEG Audio Layer 3) format or AAC (Advanced Audio Coding) format is suitable as the music data DM. In the first embodiment, the song name extracted from the metadata in the song data DM is designated as the attribute information DA.

  Each of the terminal device 10A and the terminal device 10B is a communication terminal such as a mobile phone (for example, a smartphone) or a personal digital assistant (PDA). When the content is introduced by the user A, the terminal device 10A transmits the identification information UIDa of the user A to the terminal device 10B by wireless information communication. Specifically, in the first embodiment, the terminal device 10A to the terminal device through acoustic communication using sound (sound waves) S as vibrations of air existing in the space between the terminal device 10A and the terminal device 10B as a transmission medium. The identification information UIDA is transmitted to 10B. More specifically, the terminal device 10A radiates the sound S corresponding to the acoustic signal AS representing the identification information UIDa of the user A as a waveform from the sound emitting unit of the terminal device 10A, and the terminal device 10B is transmitted from the terminal device 10A. The radiated sound S is picked up and the identification information UIDa of the user A is specified. As described above, since the frequency band of the acoustic signal AS is sufficiently high, the sound S radiated according to the acoustic signal AS for transmission of the identification information UIDa is hardly perceived by the user. In the above example, the sound within the audible band (18 kHz to 20 kHz) is illustrated, but the identification information can also be transmitted by acoustic communication using sound outside the audible band such as ultrasonic waves.

  FIG. 2 is a functional block diagram of the terminal device 10B. As illustrated in FIG. 2, the terminal device 10 </ b> B includes a control unit 11, a communication unit 12, a reception unit 13, a storage unit 14, a touch panel 15, and a sound emission unit 16. The control unit 11 is an arithmetic processing device that comprehensively controls each element of the terminal device 10B. The storage unit 14 stores a program executed by the control unit 11 and various data used by the control unit 11. For example, the storage unit 14 stores the identification information UIDa of the user A transmitted from the terminal device 10A. For example, the storage unit 14 stores an application program (“content introduction application”) for using the content introduction service. The communication unit 12 communicates with the service providing system 20 and the content server 30 via the communication network N. The communication between the terminal device 10B and the communication network N is typically wireless communication. However, for example, when a stationary personal computer or the like is used as the terminal device 10B, the terminal device 10B and the communication network N Can also be wired.

  The touch panel 15 is an input in which a display unit (for example, a liquid crystal display panel) that displays various images under the control of the control unit 11 and an input unit for a user to input an instruction to the terminal device 10B are integrated. Output equipment. Note that the input unit may be configured as a device having a plurality of operators provided separately from the display unit, or the sound collection unit 13A for inputting an instruction to the terminal device 10B by voice may be employed as the input unit. Is possible. The sound emitting unit 16 (speaker or earphone) reproduces the sound instructed from the control unit 11.

  As illustrated in FIG. 2, the reception unit 13 is a functional element realized in cooperation with the sound collection unit 13 </ b> A when the control unit 11 executes a program stored in the storage unit 14. The sound collection unit 13A (microphone) collects the sound S including the identification information UIDa of the user A. The ID extraction unit 13B is an element (identification information acquisition unit) that acquires the identification information UIda of the user A from the sound S collected by the sound collection unit 13A. Specifically, the ID extraction unit 13B extracts a signal component (corresponding to the acoustic signal AS) in the frequency band including the identification information from the collected sound S using a high-pass filter, and performs the diffusion performed when the acoustic signal AS is generated. The identification information UIDa of the user A is decoded by passing through a matched filter using the spreading code used for modulation as a coefficient. That is, the sound collection unit 13A and the ID extraction unit 13B are wireless information communication between the terminal device 10A (transmission device) and the terminal device 10B capable of transmitting the identification information UIDA of the user A who is the content introducer. , And functions as the receiving unit 13 that receives the identification information UIDA of the user A.

  FIG. 3 shows an example of the stored contents of the introduction content management table TBL1 stored in the introduction content management server 20B. As shown in the figure, the introduction content management table TBL1 stores the identification information MID of the music to be introduced by the user in association with the identification information UID of each user (introducer) who uses the content introduction service. . 10 A of terminal devices of this embodiment identify the music information which it is going to introduce to other users including user B via communication network N at arbitrary timings after receiving acoustic signal AS from ID assignment server 20A. The MID is transmitted to the introduction content management server 20B together with the identification information UIDa of the user A. The introduction content management server 20B stores the received identification information MID in the introduction content management table TBL1 in association with the identification information UIDa of the user A. In the illustrated example, two pieces of identification information “MIDd, MIDe” are stored in association with the identification information “13525”, and three pieces of music identification information “MIDa, MIDb, MIDc” are associated with the identification information “13526”. The identification information “MIDd” of one piece of music is stored in association with the identification information “13527”. In this table, “13526” is user A's identification information UIDA, and three pieces of music identification information “MIDa, MIDb, MIDc” are associated with each other.

  FIG. 4 shows an example of the stored contents of the privilege management table TBL2 stored in the privilege management server 20C. As illustrated, the privilege management table TBL2 stores privilege information indicating points owned by each user in association with the identification information UID of each user. The points are virtual currency values that are consumed as consideration for enjoying various services. In the illustrated example, the privilege information of “10” points associated with the identification information “13525”, “5” points associated with the identification information “13526”, and “26” points associated with the identification information “13527”. Are stored. The number of points indicated by the privilege information corresponding to the identification information UIDa of the user A in the privilege management table TBL2 increases by a predetermined amount each time the identification information UIDa of the user A is reported from the terminal device 10B. Each time you use a point, it decreases by the amount used. That is, the privilege management table TBL2 is always kept up-to-date.

As illustrated in FIG. 2, the control unit 11 further functions as a content information acquisition unit 11A and a report unit 11B by executing a program stored in the storage unit 14. The content information acquisition unit 11A acquires the identification information MID of the music associated with the identification information UIDA of the user A received by the reception unit 13 from the introduction content management server 20B via the communication unit 12, and stores the identification information MID. The music attribute information DA is acquired from the content server 30. Specifically, the content information acquisition unit 11A transmits the identification information UIDA of the user A acquired by the ID extraction unit 13B to the introduction content management server 20B via the communication unit 12 and the communication network N. The introductory content management server 20B refers to the introductory content management table TBL1, and returns the music identification information MIDa, MIDb, and MIDc associated with the identification information UIDa of the user A received from the terminal device 10B to the terminal device 10B. . The content information acquisition unit 11A transmits the identification information MIDa, MIDb, and MIDc to the content server 30, and acquires the attribute information DAa, DAb, and DAc of each song.
The touch panel 15 notifies the user B of the terminal device 10B by displaying the music attribute information DA acquired by the content information acquisition unit 11A. Instead of (or in addition to) the notification by display, the attribute information DA may be notified by emitting sound corresponding to the attribute information DA from the sound emitting unit 16.

  The reporting unit 11B reports the identification information UIDa of the user A (that is, the music introducer for the user B) received by the receiving unit 13 to the privilege management server 20C via the communication unit 12. Specifically, the reporting unit 11B transmits the identification information UIDa of the user A acquired by the ID extraction unit 13B to the privilege management server 20C via the communication unit 12 and the communication network N, thereby managing the identification information UIDa. Report to server 20C. The number-of-music information indicating the number of songs acquired by the user B is attached to the identification information UIda. In the privilege management table TBL2, the privilege management server 20C includes the number of songs acquired (purchased) by the user B through the introduction from the user A to the number of points in the privilege information associated with the identification information UIda received from the terminal device 10B. A multiplication value with a predetermined number of points is added. In the present embodiment, the predetermined number of points per music piece is “1”. That is, each time a music introducer introduces a song to another user (more accurately, every time another user purchases one introduced song), the privilege of “1 point” is given. Is granted. In addition, the kind and number of the privilege provided are arbitrary. For example, the given points are not determined according to the number of music pieces, and each time the identification information UIda is reported from the report unit 11B, the information is stored in association with the identification information UIda regardless of the number of introduced music pieces. A predetermined amount of points may be added to the given points. In this case, the reporting unit 11B reports the identification information UIDa to the privilege management server 20C without attaching the number-of-music information to the identification information UIDa.

  The configuration (not shown) of the terminal device 10A is the same as that of the terminal device 10B. The control unit of the terminal device 10A decodes the identification information UIDa of the user A from the acoustic signal AS received from the ID assignment server 20A by the same processing (spread modulation and matched filter) as the ID extraction unit 13B of the terminal device 10B. The acoustic signal AS received from the ID assigning server 20A and the decoded identification information UIDa are stored in the storage unit. The identification information UIDa stored in the storage unit is used for communication with the service providing system 20. The acoustic signal AS stored in the storage unit is radiated as the sound S by being supplied to the sound emitting unit.

  Next, a specific example of the operation of each device (service providing system 20, content server 30, terminal device 10A, terminal device 10B) in the communication system 100 will be described with reference to FIG. At the time of starting the operation of FIG. 5, music data DMa, DMb, and DMc respectively corresponding to the music a, b, and c are stored in the storage unit of the terminal device 10A of the user A, and the storage unit of the terminal device 10B of the user B 14 assumes a case where music data DMa, DMb, and DMc are not stored. A content introduction application is stored in each of the storage unit of the terminal device 10A and the storage unit 14 of the terminal device 10B, and the user B receives music data DMa, DMb and DMc shall be purchased.

  When the content introduction application is activated on the terminal device 10A of the user A, the control unit of the terminal device 10A requests the service providing system 20 for the identification information UIDA of the user A (S1). In response to this, the ID assignment server 20A of the service providing system 20 generates an acoustic signal AS representing the identification information UIDA (S2) and returns it to the terminal device 10A (S3). Acquisition of the identification information UIda (S1 to S3) is executed when the content introduction application is first activated. The acoustic signal AS is stored in the storage unit of the terminal device 10A (S4) and used for subsequent acoustic communication. Further, the control unit of the terminal device 10A decodes the identification information UIDa from the acoustic signal AS and stores it in the storage unit.

  Thereafter, in the terminal device 10A, when the user A designates a song to be introduced from the user A to the user B (S5), the control unit of the terminal device 10A determines the identification information (MIDa, MIDb, MIDc) of the designated song. Is transmitted to the introduction content management server 20B of the service providing system 20 together with the identification information UIDa stored in the storage unit (S6). For example, the song is designated by displaying on the touch panel 15 images corresponding to the song names of the songs a, b, and c extracted from the metadata of the song data DMa, DMb, and DMc stored in the storage unit. This is executed by tapping the “Share” button after selecting. The introduction content management server 20B registers the identification information MIDa, MIDb, and MIDc of the music pieces a, b, and c in the introduction content management table TBL1 in association with the identification information UIDa of the user A (S7). For example, the existing identification information MID stored in correspondence with the identification information UIda is updated (overwritten) to the music identification information MID (MIDa, MIDb, MIDc) newly designated by the user A. As a result, the contents stored in the introduction content management table TBL1 are as shown in FIG. Further, the terminal device 10A reads out the acoustic signal AS including the identification information UIDa of the user A from the storage unit in response to the operation of the above-described “Share” button, and outputs the acoustic S corresponding to the acoustic signal AS as a sound emitting unit (see FIG. (S8).

  In the terminal device 10 </ b> B, the sound S is collected by the sound collection unit 13 </ b> A, and the control unit 11 (ID extraction unit 13 </ b> B) of the terminal device 10 </ b> B acquires the identification information UIda of the user A from the sound S and stores it in the storage unit 14. (S9). That is, as described above, when the control unit 11 executes step S9, a functional element (receiving unit 13) that receives the identification information UIDA of the user A through wireless information communication with the terminal device 10A is realized. .

  Next, the control unit 11 of the terminal device 10B transmits the identification information UIDa of the user A received from the terminal device 10A from the communication unit 12 to the service providing system 20 (S10). The introduction content management server 20B of the service providing system 20 reads the music identification information MIDa, MIDb, MIDc stored in association with the received identification information Uida of the user A from the introduction content management table TBL1 (S11), It transmits to the terminal device 10B (S12). The control unit 11 of the terminal device 10B transmits the received music identification information MIDa, MIDb, and MIDc to the content server 30 via the communication unit 12 (S13), and the content server 30 transmits the music identification information MIDa, MIDb, The attribute information DAa, DAb, DAc (that is, information indicating the song name) of the songs a, b, c corresponding to MIDc is acquired (S14). The control unit 11 causes the touch panel 15 to display images (for example, a list of attribute information DA) corresponding to the acquired attribute information DAa, DAb, DAc (S15). That is, the music name of the music introduced from the user A is presented. At this time, the “Buy” button to be tapped when the user B purchases music is also displayed on the touch panel 15. As understood from the above description, the introduction content management server 20B responds to the identification information UIDa of the user A received by the receiving unit 13 via the communication unit 12 by the control unit 11 executing steps S10 to S14. A functional element (content information acquisition unit 11A) that acquires information about the attached music (that is, attribute information DA) is realized. Moreover, the control part 11 performs step S15, and the functional element (notification part) which notifies the attribute information DA of music to the user B of the terminal device 10B is implement | achieved.

  The user B of the terminal device 10 </ b> B can select a song that he / she wishes to purchase from among a plurality of songs displayed on the touch panel 15. When the user B refers to the attribute information DA of the notified music and taps the “Buy” button of the desired music (hereinafter referred to as “selected music”) (S16), the control unit 11 sets the identification information MID of the selected music. It transmits to the content server 30 (S17). FIG. 5 illustrates a case where the user B selects the music pieces a, b, and c, and the identification information MID (MIDa, MIDb, MIDc) of each selected music piece is transmitted to the content server 30. The content server 30 performs music data DM (DMa, DMb, and DMc in the example of FIG. 5) corresponding to the identification information MID of the selected music received from the terminal device 10 after executing a series of procedures such as authentication processing and billing processing. Is transmitted to the terminal device 10B via the communication network N (S18).

The control unit 11 of the terminal device 10B stores the music data DM of each selected song received from the content server 30 in the storage unit 14 (S19), and receives the identification information UIda of the user A via the communication unit 12 as a service providing system 20. (S20) The privilege management server 20C of the service providing system 20 updates the privilege information stored in association with the reported identification information UIDa of the user A in the privilege management table TBL2 (S21). That is, a privilege is given to the user A who is an introducer on condition that the user B introduced the music from the user A purchases the music. Specifically, in the privilege management table TBL2 shown in FIG. 4, the number of songs “3” introduced by the user A to the user B is added to the current point number “5” of the privilege information associated with the identification information UIDA of the user A. And a multiplication value “3” of the predetermined number of points “1” is added. As a result, the number of points owned by user A increases from “5” to “8”.
That is, when the control unit 11 executes step S20, a functional element (report unit 11B) that reports the identification information UIDA of the user A to the privilege management server 20B via the communication unit 12 is realized.

  As described above, in this embodiment, the identification information UIDa of the music introducer (user A) is transmitted to the terminal device 10B of the user B and then reported to the privilege management server 20C. Incentives for introduction increase, and as a result, introduction of music between users can be performed more actively. Also, since it is possible to introduce a plurality of pieces of music simply by transmitting the identification information UIDA of the user A to the user B, a plurality of pieces of music can be introduced as compared with the case where the pieces of music identification information are introduced and the pieces of music are introduced. This eliminates the trouble of transmitting the identification information of the music and reduces the processing load in communication.

  Furthermore, in this embodiment, the sound S representing the identification information UIDA of the user A is collected by the sound collection unit 13A, and the identification information UIda is acquired from the collected sound S. The terminal device 10B can receive the identification information UIDa without establishing an individual communication link between the terminal device 10B and the transmission device capable of transmitting the identification information UIDa. Further, there is an advantage that the identification information can be received as long as the terminal device 10B includes the sound collection unit 13A. That is, even when the terminal device 10B does not have a short-range (or non-contact) communication function such as Bluetooth or FeliCa, the introducer identification information UID can be received. Furthermore, since the sound S can be collected from the sound collection unit of another terminal device in the space where the terminal device 10A and the terminal device 10B exist, users other than the user B can freely receive the identification information UIDa. Therefore, introduction of content can be promoted more efficiently.

  In the configuration in which the music identification information MID is transmitted from the terminal device 10A to the terminal device 10B, a large amount of data is exchanged between the terminal device 10A and the terminal device 10B, especially when introducing a large number of music (and communication). Takes a long time). In the first embodiment, since the user B can receive a plurality of pieces of music as long as the introduction information UIDa of the user A who is the introducer is received, for example, even if there are a large number of music to be introduced, the music identification information MID is used. There is an advantage that the amount of data transmitted from the terminal device 10A to the terminal device 10B can be reduced (communication time can be shortened) as compared with the case of giving and receiving. Note that the above-described acoustic communication using sound waves as air vibration as a transmission medium tends to have a lower communication speed and communication capacity than, for example, wireless communication using radio waves as a transmission medium. Therefore, the configuration of the first embodiment that can suppress the amount of data transmitted from the terminal device 10A to the terminal device 10B is particularly suitable for a configuration using acoustic communication.

  Further, in the configuration in which the music identification information MID is transmitted from the terminal device 10A to the terminal device 10B by acoustic communication, an acoustic signal including the music identification information MID selected by the user A must be generated for each music by the terminal device 10A. There is. In the first embodiment, since the identification information UIDA of the user A is transmitted from the terminal device 10A to the terminal device 10B, it is possible to continuously use the identification information UIda acquired in advance from the ID assignment server 20A. It is not necessary to generate an acoustic signal including the identification information MID of the music to be introduced for each selection by the user A. Therefore, there is an advantage that the processing load on the terminal device 10A is reduced.

  In addition, in the present embodiment, since the control unit 11 notifies the user B of the terminal device 10B by displaying the attribute information DA of the music acquired from the content server 30, the user B of the terminal device 10B displays It is possible to decide whether or not to purchase after confirming the attribute information DA.

Moreover, in this embodiment, when the user B of the terminal device 10B acquires (purchases) the music introduced by the user A, the identification information UIDA of the user A is reported to the privilege management server 20C. That is, it becomes possible to give a privilege to the user A on condition that the user B who is the introducer actually purchases the music introduced by the user A. Therefore, there is an advantage that profits are surely returned not only to the user A but also to the service provider who distributes the music.
Furthermore, in this embodiment, the service providing system 20 manages the music that the user A intends to introduce to the user B in the introduction content management server 20B, and the terminal device 10B of the user B uses the music. When acquired (purchased), the user B's terminal device 10B reports the user A's identification information UIDa to the privilege management server 20C of the service providing system 20, so that the service providing system 20 introduces the music introduced between the users. Can be grasped. Therefore, for example, based on the user B's preference for music, a content provider such as the content server 30 provides information for recommending music having a similar tendency to the user B or selecting music to be played in a store or the like. There is an advantage that can be provided.

Second Embodiment
Next, a second embodiment of the present invention will be described. In addition, about the element which an effect | action and function are the same as that of 1st Embodiment in each form illustrated below, the reference | standard referred by description of 1st Embodiment is diverted, and each detailed description is abbreviate | omitted suitably.

  FIG. 6 is a diagram showing an overall configuration of a communication system 200 according to the second embodiment of the present invention. As shown in the figure, the communication system 200 according to the second embodiment is different from the communication system 100 according to the first embodiment in that a sound emitting system 10C is provided instead of the terminal device 10A. The sound emission system 10C is a music reproduction system in a store C (restaurant, retail store, etc.), for example, and includes an ID storage unit 14c, a sound emission unit (speaker) 16c installed in the store C, and a music reproduction unit 18c. . As in the first embodiment, the sound emission system 10C receives the acoustic signal AS indicating the identification information UIDc of the store C from the ID assignment server 20A of the service providing system 20 and stores it in the ID storage unit 14c in advance ( S1-S4 in FIG. The sound emitting system 10C superimposes (adds) the acoustic signal AS indicating the identification information UIDc stored in the ID storage unit 14c on the acoustic signal MS indicating the music to be reproduced (for example, the music b), to the sound emitting unit 16. The sound S corresponding to the sound signal [AS + MS] is radiated from the sound emitting unit 16c. That is, the sound emission system 10C is different from the first embodiment in that the identification information UIDc is transmitted in parallel with the reproduction of the musical sound. On the other hand, it is the same as in the first embodiment in that the identification information UIDc is transmitted to the terminal device 10B by acoustic communication using sound waves as a transmission medium.

  Further, in the communication system 200 according to the second embodiment, as in the first embodiment, the identification information (for example, identification information corresponding to each of the music pieces a, b, and c) that the store C intends to introduce to the user B is provided. MIDa, MIDb, MIDc) are associated with the identification information UIDc of the store C and stored in the introduction content management table TBL1 of the introduction content management server 20B (S5 to S7).

  In the terminal device 10B of the second embodiment, when the sound S corresponding to the acoustic signal [AS + MS] is collected by the sound collection unit 13A, the control unit 11 (ID extraction unit 13B) uses, for example, a high-pass filter. The acoustic signal [AS + MS] is separated into the acoustic signal AS and the acoustic signal MS, and the identification information UIDc of the store C is extracted from the acoustic signal AS (S8, S9). Then, as in the first embodiment, the control unit 11 transmits the identification information UIDc of the store C from the communication unit 12 to the introduction content management server 20B of the service providing system 20, and is stored in association with the identification information UIDc. The music identification information MIDa, MIDb, MIDc is acquired (S10 to S12). Subsequently, the control unit 11 transmits the identification information MIDa, MIDb, and MIDc of the music pieces a, b, and c from the communication unit 12 to the content server 30, and each piece of attribute information DAa, DAb, DAc ( (Song name) is acquired, and an image (an image showing a song name) corresponding to the acquired attribute information DAa, DAb, DAc is displayed on the touch panel 15 (S13 to S15). When the user B purchases the music piece b, for example, a privilege is given to the store C (S16 to S21). In the second embodiment, the same operations and effects as in the first embodiment are achieved.

<Modification>
Various modifications can be made to the embodiment exemplified above. An example of a specific modification is as follows. Two or more aspects may be arbitrarily selected from the following examples and combined.

(1) Modification 1
In the above embodiment, one identification information UID is assigned to each introducer, but a plurality of identification information UIDs can be assigned to the introducer. For example, a configuration in which a plurality of identification information UIDs corresponding to different time zones is given to an introducer may be employed. In this case, it is possible to change the music to be introduced by one introducer according to the time zone. In addition, a configuration in which different identification information UIDs are assigned to each genre of music to be introduced, or a configuration in which the identification information UID becomes invalid after a predetermined time has elapsed can be employed. In the above embodiment, the acquisition of identification information UIda (S1 to S3 in FIG. 5) by the terminal device 10A of the introducer (user A) is executed when the content introduction application is first activated. However, the present invention is not limited to this. For example, the user A may acquire the information every time one or more pieces of music are introduced to another user. That is, each time a piece of music to be introduced is registered in the introduction content management server 20B, the acquisition of the identification information UIda (S1 to S3) is executed as a previous stage of the registration.
In a case where a plurality of identification information UIDs can be assigned to an introducer, for example, in the introduction content management table TBL1 (FIG. 3), for each set of user identification information UID and music identification information MID, The introducer's account identification information AID is stored in association with each other. The account identification information AID is information that uniquely identifies the account of the content introduction service subscriber (introducer). In the privilege management table TBL2 (FIG. 4), privilege information for each account identification information AID is stored instead of the user identification information UID. When the introducer identification information UIDa is reported to the privilege management server 20C of the service providing system 20 in step S20 of FIG. 5, the privilege management server 20C reads the account identification information AID corresponding to the identification information UIDa from the introduction content management table TBL1. And the privilege information corresponding to the account identification information AID is updated (S21). Note that a table in which the user identification information UID and the account identification information AID are associated with each other is separately stored in the ID assignment server 20A, the introduction content management server 20B, the privilege management server 20C, or any server of the service providing system 20. It may be.

(2) Modification 2
In the above embodiment, the terminal device 10B transmits the identification information UIDa of the user A to the introduction content management server 20B to acquire the music identification information MID, and transmits the acquired music identification information MID to the content server 30 to transmit the music. Attribute information (music name) is acquired, but is not limited thereto. For example, when the introduction content management server 20B of the service providing system 20 receives the identification information UIDA of the user A from the terminal device 10B, the introduction content management server 20B transmits the music identification information MID to the content server 30 to send the music attribute information DA ( It is also possible to transmit the acquired attribute information DA together with, for example, the identification information MID of the music to the terminal device 10B. Also, the introduction content management server 20B receives the identification information UIDa of the user A from the terminal device 10B as a trigger, transmits the music identification information MID to the content server 30, acquires the music data DM, and sends it to the terminal device 10B. A transmission configuration may also be employed. As can be understood from the above description, the content information acquisition unit is included as an element for acquiring information related to the content associated with the identification information UID of the introducer (user A), In the above example, the introduction content management server 20B and the content server 30) are arbitrary. In addition to content identification information (music identification information MID), content information includes content attribute information (music attribute information DA) and content itself (music data DM).

(3) Modification 3
In the above embodiment, when the terminal device 10B receives the music identification information MID from the introduction content management server 20B, it acquires the music attribute information DA from the content server 30, and then the user B of the terminal device 10B purchases the music. When it is determined, the music data DM is acquired. However, the present invention is not limited to this. For example, the terminal device 10B may acquire the music data DM from the beginning without acquiring the music attribute information DA from the content server 30. Can do.

(4) Modification 4
In the above embodiment, the ID assigning server 20A generates an acoustic signal AS indicating the identification information UID of the introducer (user A or store C) and transmits it to the introducer's terminal device 10A or the sound emission system 10C. For example, the terminal device 10A or the sound emission system 10C may have a function of generating the acoustic signal AS. In the above-described embodiment, the identification information UIDa of the user A or the identification information UIDc of the store C is decoded from the acoustic signal AS in the terminal device 10A or the sound emission system 10C of the introducer. It is also possible to decrypt the identification information (UIDa, UIDc). Further, the service providing system 20 may include the ID extracting unit 13B instead of the terminal device 10B.

(5) Modification 5
In the said embodiment, when the user B purchased the music, it was set as the structure by which a privilege is provided to the user A, However, The content of the conditions for which a privilege is provided is arbitrary. For example, it is possible to adopt a configuration that requires the user B to download the music data DM when the music is free, or a configuration that requires the acquisition of the music identification information MID or the attribute information DA.

(6) Modification 6
In the above embodiment, the case where the introducer's identification information UID is transmitted from the terminal device 10A to the terminal device 10B by acoustic communication using a sound wave (air vibration) propagating between the devices as a transmission medium has been described. The communication method is not limited to the above examples. For example, the identification information UID may be transmitted by electrical communication using a radio wave transmitted between devices such as Bluetooth and FeliCa as a transmission medium. In other words, in the present invention, the transmission of the identification information UID is comprehensively performed as information communication realized by using a transmission medium existing in the space between devices without interposing a wired transmission path, that is, “radio information communication”.
