Description

  The present invention relates to a content use system that uses content data.

  In this specification, “contents” are sent from a caller to a user via a wireless (TV radio wave or the like) or a wired (Internet etc.), and are sentence, voice, music, still image, and moving image. , Data, programs, etc., or information expressed in a complex form thereof.

  2. Description of the Related Art In recent years, music and moving images can be reproduced by small portable communication terminals represented by mobile phones. In such a mobile communication terminal, the storage capacity is limited due to the reduction in size and weight, so that the technology of compressing and recording recorded music has been advanced, while a sound source such as MIDI used for a ring melody of a mobile phone has been mounted. Many terminals adopt a technique for reducing the size of data. MIDI is a technology used in commercial karaoke, and karaoke is being realized by adopting MIDI in mobile phones.

  On the other hand, with the progress of digital technology, home appliances, particularly audio / video devices, use the Internet and realize various functions other than the intended use by software. For example, some digital televisions are equipped with a WWW (World Wide Web) browsing function, in addition to the function of viewing broadcast video, and can download karaoke data and enjoy karaoke.

  Conventional technologies related to mobile phones with karaoke playback functions and digital televisions operate mobile phones without karaoke functions and karaoke music data playback devices based on separate operation systems when enjoying karaoke in a mobile environment. This is a technique for solving the inconvenience that had to be solved (for example, see Patent Document 1). Further, it is a technique for solving the inconvenience of having to operate a digital TV and a karaoke music data reproducing apparatus without a function of coordinating between apparatuses when operating karaoke in a living environment based on different operation systems.

Mobile phones and digital televisions are provided with communication means for connecting to the Internet, music reproduction means such as ringtones and alarm sounds, character / image display means using a liquid crystal display or CRT, and operation means using dial buttons and a remote control. . By downloading the karaoke music data for the music specified by the operation means from the karaoke service provider by the communication means, reproducing the music by the reproduction means and displaying the corresponding lyrics and images on the display means, any external device It is possible to enjoy karaoke by itself without the need for karaoke.
JP-A-2002-244681

  However, in portable communication terminals, portability is emphasized by reducing the size of a screen to be mounted and making speakers compact. On the other hand, karaoke is a content that many people want to enjoy. However, it is virtually impossible for everyone to look into and enjoy the screen of the mobile phone. Furthermore, since the volume of the mobile phone is low and there is no echo, it is not possible to realize a satisfactory way of enjoying karaoke.

  In addition, when an Internet connection function is added to a digital television set, a modem for dial-up or broadband connection is installed. In order to enjoy online karaoke in the living room, it is necessary to run a telephone line or a LAN line inside the house. Further, the communication service of the communication device and the communication karaoke service are provided by different service providers, and the user needs to conclude a communication service contract of the communication device and a contract of the communication karaoke service together. (On the other hand, in mobile phones, it is common to pay for content based on information at the time of telephone contracts.) Online registration has also become common, but credit card numbers flow through the network Many users are worried about this.

  An object of the present invention is to provide a content use system that solves the restrictions on the use of contents in a portable communication terminal and the increase in cost and the inconvenience of the procedure for using contents when an Internet connection is realized in a home electric appliance. And

  In this system, content is transferred from a portable communication terminal having a communication function to a content service provider to a content use device having a content reproduction function but not having a communication function to the content service provider by infrared rays or the like. For example, it is possible to obtain the latest karaoke music from a network and reproduce the karaoke music on the content using apparatus.

  In the present invention, the portable communication terminal is applied to a mobile phone or the like having an infrared communication function, and the content using device is applied to a digital television or the like having an infrared communication function. For example, karaoke can be enjoyed without having to sign a new content contract for a digital television and separately sign a content contract and pay a basic fee twice as much as a mobile phone contract. In addition, it is possible to use a method in which data once stored in a digital television is read out to a mobile phone and further transferred to another home electric appliance to enjoy karaoke. It is also possible to share functions according to the performance of the terminal and the device, and it is possible to provide various and more suitable ways of enjoying content reproduction. By utilizing the light receiving / emitting unit of the infrared remote controller, it is possible to indirectly download content from a content service provider to a content utilization device such as a digital television while maintaining hardware cost as a home appliance.

  Hereinafter, an embodiment of the present invention will be described. The present invention is not limited to these embodiments at all, and can be implemented in various modes without departing from the gist thereof.

  The relationship between the following embodiments and the claims is as follows.

  In the first embodiment, claims 1, 2, and 3 will be mainly described.

  The second embodiment will mainly describe Claims 4, 5, 6, and the like.

In the third embodiment, claims 7 and 8 will be mainly described.
<< Embodiment 1 >>

  <Overview of Embodiment 1>

  The present embodiment relates to a content use system including a mobile communication terminal and a content use device.

  The feature of the present embodiment is that, by operating the mobile communication terminal in a predetermined procedure, one or a plurality of data contents can be downloaded by the mobile communication terminal and transferred to the content using device by infrared rays or the like, so that Can be reproduced. In addition, by holding the bridge media such as the SD memory card, the content using apparatus can reproduce the content not only at the time of downloading but also any number of times thereafter. Also, by downloading the difference data with respect to the data once downloaded, the content can be reproduced with the data that has been upgraded based on the data already held. Alternatively, the content can be reproduced in a new way of enjoying by changing the combination of the stored data. By being able to use data that has been downloaded once, the user can reduce costs and time associated with content reproduction. Furthermore, the mobile communication terminal can also hold the content data received by the mobile communication terminal by holding the bridge media. For example, it is possible to transfer the data to a plurality of content using devices and reproduce the data. It becomes.

  FIG. 1 shows an example of the concept of the present embodiment.

  The content use system of the present embodiment includes a portable communication terminal (0120) and a content use device (0130). The mobile communication terminal (0120) downloads a content from a content server (0110) that provides the content via a network. Communication in the network may be wired or wireless. The mobile communication terminal (0120) transfers the downloaded content to the content using device (0130). The content using device (0130) can store the transferred content in the bridge media. Also, the mobile communication terminal (0120) cannot directly record the content downloaded from the content server (0110) on the bridge media, but when the mobile communication terminal (0120) receives the content transmitted from another device or the like, the received content is Can be recorded directly on the bridge media.

  <Configuration of First Embodiment>

  Examples of the functional blocks according to the present embodiment are shown in FIGS.

  The content use system shown in FIG. 2 has a basic configuration in the present embodiment, and the content use systems shown in FIGS. 3 and 4 further have new functions based on the content use system of FIG. Things.

  First, the content use system shown in FIG. 2 includes a “portable communication terminal” (0210) and a “content use device” (0220).

  The mobile communication terminal (0210) includes a "charging processing unit" (0211), a "first content receiving unit" (0212), a "content transfer unit" (0213), and a "bridge media recording and holding unit" (0214). ).

  The “charging processing unit” (0211) has a function of performing processing for charging in accordance with the reception of the content of the portable communication terminal (0210). At present, a contract is basically required for using a mobile communication terminal such as a mobile phone, and personal information is registered at the time of the contract. Since a mechanism for paying the usage fee of the content together with the payment of the basic fee and the call fee of the mobile phone contract is generally established, such a mechanism may be used.

  The “first content receiving unit” (0212) has a function of receiving content. The communication method for receiving may be wired or wireless, and the communication method is not particularly limited. Further, the communication may be wireless, for example, communication using infrared rays, or communication using a wireless communication technique typified by Bluetooth or 802.11. In recent years, these wireless communication technologies have rapidly spread as communication technologies between home electric appliances.

  The “content transfer unit” (0213) has a function of transferring the content received by the first content reception unit (0212). Like the first content receiving unit (0212), the communication method is not particularly limited.

  The “bridge media recording and holding unit” (0214) cannot directly record the content received by the first content receiving unit (0212). That is, in principle, a bridge medium in which contents are stored is read in a bridge medium holding unit (0222) described later of the content using device (0220). However, it has a function of directly recording the content received by the second content receiving unit described later, which is convenient. There are various standards for the bridge media, such as an SD memory card and a memory stick, but the type is not particularly limited. Further, instead of such an external memory, an internal memory such as a RAM may be used.

  The content use device (0220) includes a "transfer content receiving unit" (0221) and a "bridge media holding unit" (0222). Here, the content use device (0220) is a device that uses the content, and the use of the content means reproduction of the content and execution of the program.

  The “transfer content receiving unit” (0221) has a function of receiving content transferred from the portable communication terminal (0210). Like the first content receiving unit (0212), the communication method is not particularly limited.

  The “bridge media holding unit” (0222) has a function of directly recording and holding the content received by the transfer content receiving unit (0221). Similarly to the bridge media recording and holding unit (0214), the standard and the like of the bridge media are not particularly limited.

  Further, the configuration of the content use system shown in FIG. 3 is different from the configuration of the content use system shown in FIG. 2 in that the billing processing unit (0311) of the portable communication terminal (0310) includes a “billing identification information holding unit” ( 0315).

  The "charging identification information holding means" (0315) holds identification information for charging related to the communication contract of the portable communication terminal (0310). As actual identification information, if a mobile phone is used, a device ID or the like may be used, and these may be used, or a telephone number or the like may be used as the identification information.

  Further, in the configuration of the content use system shown in FIG. 4, in addition to the configuration of the content use system shown in FIG. 3, the portable communication terminal (0410) has a “second content receiving unit” (0416).

  The “second content receiving unit” (0416) has a function of receiving content. Like the first content receiving unit (0412), the communication method is not particularly limited. The content received by the second content receiving unit (0416) can be directly recorded on the bridge media recording and holding unit (0414).

  In the configuration of FIGS. 2, 3, and 4, the transfer unit and the first content receiving unit of the mobile communication terminal are configured to execute the program or the content obtained by external communication with the mobile communication terminal. May be realized. In this case, the program or the content may not be able to recognize the bridge media recording unit, and it is significant that the program or the content is recorded on the bridge media by the content using device and can be used by the portable communication terminal. . The transfer unit and the first content receiving unit may be realized by a so-called embedded program. On the other hand, there is a case where the content received by the first content receiving unit is complex and the content handled integrally includes a plurality of sub-contents. In such a case, there may be a case in which recording on the bridge media recording unit cannot be performed due to an attribute of a part of the sub-contents for policy reasons. The attribute may be realized as a so-called flag (sub-content).

  <Specific Example of First Embodiment>

  A specific example of this embodiment will be described. 5, 6, and 7 show examples of specific examples.

  The content use system shown in FIG. 5 has a basic configuration in the present embodiment, and the content use systems shown in FIGS. 6 and 7 have further new functions based on the content use system of FIG. Things.

  First, FIG. 5 will be described in detail. It is assumed that the mobile communication terminal (0510) has downloaded, for example, the content “Rion Heart” by the first content receiving unit (0512). In the charging processing unit (0511), processing for charging is performed by the downloaded content "Rion Heart", and for example, a message such as "Debiting the download fee of 1000 yen from the bank account of the content service provider contract" is transmitted. Processing is performed. Further, the content received by the first content receiving unit (0512) cannot be directly stored in the bridge media recording and holding unit (0514). The content “Rion Heart” downloaded by the first content receiving unit (0512) is transferred to the outside by the content transfer unit (0513). The transfer destination does not necessarily have to be the content use device (0520), but it is assumed here that the transfer has been made to the content use device (0520). In the content use device (0520), the content transfer unit (0521) receives the content “Rion Heart” transferred from the content transfer unit (0513) of the mobile communication terminal (0510). After that, the content “Rion Heart” is recorded by the bridge media holding unit (0522). In addition, the received content is reproduced and used by the content use device (0520).

  The difference between the content use system shown in FIG. 6 and the content use system shown in FIG. 5 is that the billing processing unit (0611) of the portable communication terminal (0610) has a billing identification information holding unit (0615). Since the method of processing by the billing processing unit (0611) differs depending on this, this point will be described in detail.

  In the billing processing unit (0611), assuming that billing identification information holding means (0615) holds billing identification information, for example, identification information "A20345", this identification information and the downloaded content "Rion Heart" are stored. For example, a process for transmitting a message such as "Debit the mobile terminal A20345 download fee of 1000 yen from the bank account of the content service provider contract" is performed.

  Further, the difference between the content use system shown in FIG. 7 and the content use system shown in FIG. 6 is that the portable communication terminal (0710) has the second content reception unit (0716). The processing related to the content receiving unit (0716) will be described in detail.

  Since the mobile communication terminal (0710) can receive the content separately by the second content receiving unit (0716), for example, if the second content receiving unit (0716) receives the content "LOVE machine", the content is received. The content "LOVE machine" is recorded and held on the bridge medium in the bridge medium recording and holding unit (0714).

  <Process Flow of First Embodiment>

  FIG. 8 illustrates an example of a processing flow in the first embodiment. The processing in the present embodiment includes the following steps.

  First, the content is downloaded (content download step S0810).

  Next, processing for charging based on the content downloaded in the content downloading step (S0810) is performed (charging processing step S0820).

  Next, the content downloaded in the content download step (S0810) is transferred (content transfer step S0830).

  Here, the order of the charging process step (S0820) and the content transfer step (S0830) may be reversed. The above steps are processing in the portable communication terminal, and the subsequent steps are processing in the content use device.

  Next, the content transferred in the content transfer step (S0830) is received (transferred content reception step S0840).

  Finally, the content received in the transfer content receiving step (S0840) is recorded on the bridge media (bridge media recording step S0850). After that, the content may be used in the content using device.

  When the portable communication terminal has the second content receiving unit and the bridge media recording and holding unit, the transfer content receiving step (S0840) and the bridge media recording step (S0850), which are processes in the content using device, are performed. Similarly, content can be received and the received content can be recorded on bridge media.

  <Effects of Embodiment 1>

As described above, according to the content using system of the present embodiment, it is possible to use the content by downloading the content including one or a plurality of data by the portable communication terminal and transferring the content to the content using device by infrared rays or the like. it can. Further, even when the content received by the portable communication terminal cannot be directly recorded on the bridge medium, the content can be used via the bridge medium of the content using apparatus.
<< Embodiment 2 >>

  <Overview of Embodiment 2>

  The present embodiment relates to a content use system including a mobile communication terminal and an electronic device.

  The feature of the present embodiment is that, by operating the mobile communication terminal in a predetermined procedure, a content composed of one or more data is downloaded by the mobile communication terminal, transferred to the electronic device by infrared rays or the like, and further transferred. By re-transferring the content to the mobile communication terminal, the content received by the mobile communication terminal can be recorded. Further, for example, it is also possible to transfer the data to a plurality of devices for reproduction.

  FIG. 9 shows an example of the concept of the present embodiment.

  The content use system of the present embodiment includes a portable communication terminal (0920) and an electronic device (0930). The mobile communication terminal (0920) downloads the content from a content server (0910) that provides the content via a network. Communication in the network may be wired or wireless. The portable communication terminal (0920) and the electronic device (0930) have transmission and reception functions, and can communicate with each other with or without other devices. That is, the mobile communication terminal (0920) and the electronic device (0930) can exchange data and control information with each other by providing an infrared communication function of transmitting and receiving content data and control data by infrared. Also, the mobile communication terminal (0920) cannot directly record the content downloaded from the content server (0910) on the bridge media, but when the content transmitted from another device or the like is received, the received content is Can be recorded directly on the bridge media.

  <Configuration of Second Embodiment>

  FIGS. 10 and 12 show examples of functional blocks according to the present embodiment.

  The content use system shown in FIG. 10 has a basic configuration in the present embodiment, and the content use system shown in FIG. 12 is based on the content use system of FIG. .

  The content use system of the present embodiment shown in FIG. 10 includes a “portable communication terminal” (1010) and an “electronic device” (1020).

  The mobile communication terminal (1010) includes a “charging processing unit” (1011), a “content receiving unit” (1012), a “content transferring unit” (1013), and a “second bridge media holding unit” (1014). And a "retransmission content receiving unit" (1015). Here, the function of the content transfer unit (1013) is the same as that of the first embodiment. As a transfer destination of the content transfer unit (1013), the electronic device (1020) can be mainly considered. The content receiving unit (1012), the second bridge media holding unit (1014), and the retransmission content receiving unit (1015) are respectively the first content receiving unit and the bridge media recording of the first embodiment. The functions of the holding unit and the second content receiving unit are the same. However, the retransferred content receiving unit (1015) differs from the second content receiving unit of the first embodiment in that the retransmitted content receiving unit (1015) receives the content transferred from the content transferring unit (1013).

  The electronic device (1020) includes a “transferred content receiving unit” (1021) and a “transferred content retransfer unit” (1022). The transfer content receiving unit (1021) has the same function as that of the first embodiment. The function of the electronic device (1020) is to retransmit the received content to the outside as it is. The portable communication terminal (1010) is mainly considered as a re-transfer destination.

  The “transferred content retransfer unit” (1022) has a function of retransferring the content received by the transfer content receiving unit (1021). The transfer content retransfer unit (1022) may perform the transfer using a bridge medium provided in the electronic device.

  The configuration of the content use system shown in FIG. 12 is different from the configuration of the content use system shown in FIG. 12 in that the billing processing unit (1211) of the portable communication terminal (1210) includes a “billing identification information holding unit” ( 1216). The function of the charging identification information holding means (1216) is the same as that of the first embodiment.

  Further, as shown in FIGS. 11 and 13, it is convenient that the electronic device has a configuration having a memory. This is because, for example, it is possible to realize a configuration in which the content received by the transfer content receiving unit is temporarily stored in the memory and can be re-transferred from the transfer content re-transfer unit later.

  <Specific Example of Second Embodiment>

  A specific example of this embodiment will be described. 14 and 16 show an example of a specific example.

  The content use system shown in FIG. 14 has a basic configuration in the present embodiment, and the content use system shown in FIG. 16 is obtained by adding new functions based on the content use system of FIG. .

  First, FIG. 14 will be described in detail. It is assumed that the mobile communication terminal (1410) has downloaded, for example, the content “Rion Heart” by the content receiving unit (1412). In the charging processing unit (1411), processing for charging is performed by the downloaded content "Rion Heart", and for example, a message such as "Debiting a download fee of 1000 yen from the bank account of the content service provider contract" is transmitted. Processing is performed. Further, the content received by the content receiving unit (1412) cannot be directly stored in the second bridge media recording and holding unit (1414). The content “Rion Heart” downloaded by the content receiving unit (1412) is transferred to the outside by the content transfer unit (1413). The transfer destination does not necessarily have to be the electronic device (1420), but it is assumed here that the transfer has been made to the electronic device (1420). The electronic device (1420) receives the content “Rion Heart” transferred from the content transfer unit (1413) of the mobile communication terminal (1410) by the transfer content receiving unit (1421). Thereafter, the content “Rion Heart” is transferred by the transfer content retransfer unit (1422). The transfer destination does not necessarily have to be the mobile communication terminal (1410), but it is assumed here that the transfer destination is the mobile communication terminal (1410).

  Since the mobile communication terminal (1410) can receive the content transferred and re-transferred from its own content transfer unit (1413) by the re-transfer content reception unit (1415), the re-transfer content reception unit (1415) Receive the content "Rion Heart". The received content "Rion Heart" is recorded and held on the bridge medium in the bridge medium holding unit (1414).

  The difference between the content use system shown in FIG. 16 and the content use system shown in FIG. 14 is that the billing processing unit (1611) of the portable communication terminal (1610) has a billing identification information holding unit (1616). The processing of the accounting processing unit (1611) is different depending on this, and this will be described in detail.

  In the billing processing unit (1611), assuming that billing identification information holding means (1616) holds identification information for billing, for example, identification information "A20345", this identification information and the downloaded content "Rion Heart" are stored. For example, a process for transmitting a message such as "Debit the mobile terminal A20345 download fee of 1000 yen from the bank account of the content service provider contract" is performed.

  FIGS. 15 and 17 show a case where the electronic device has a memory. In this case, the content “Rion Heart” received by the transfer content receiving unit is stored in a memory and then transferred by the transfer content retransfer unit.

  <Process Flow of Second Embodiment>

  FIG. 18 illustrates an example of a processing flow according to the second embodiment. The processing in the present embodiment includes the following steps.

  First, the content is downloaded (content download step S1810).

  Next, processing for charging based on the content downloaded in the content downloading step (S1810) is performed (charging processing step S1820).

  Next, the content downloaded in the content download step (S1810) is transferred (content transfer step S1830).

  Here, the order of the charging process step (S1820) and the content transfer step (S1830) may be reversed.

  Next, the content transferred in the content transfer step (S1830) is received (transferred content reception step S1840).

  Next, the content received in the transfer content receiving step (S1840) is re-transferred (transferred content re-transfer step S1850).

  Next, the content re-transferred in the transfer content re-transfer step (S1850) is received (re-transfer content receiving step S1860).

  Finally, the retransmitted content received in the retransmitted content receiving step (S1860) is recorded on the bridge media (bridge media recording step S1870).

  In the above steps, steps S1810 to S1830, steps S1860 and S1870 are processes in the portable communication terminal, and steps S1840 and S1850 are processes in the content use device.

  FIG. 19 shows the flow of processing when the electronic device has a memory. The difference from FIG. 18 is that buffering in the memory is performed between the transfer content receiving step (S1940) and the transfer content retransfer step (S1960) (buffering step S1950).

  <Effect of Embodiment 2>

As described above, according to the content usage system of the present embodiment, the content including one or a plurality of data is downloaded by the mobile communication terminal, transferred to the electronic device by infrared rays or the like, and the transferred content is further transferred to the mobile communication terminal. By re-transmitting the content to the terminal, the content received by the mobile communication terminal can be recorded. That is, even if the content downloaded by the mobile communication terminal cannot be directly recorded on the bridge media, the content can be recorded by being re-transferred from the electronic device. Further, for example, it is also possible to transfer the data to a plurality of devices for reproduction.

  The content use device (2130) includes a “use bridge media holding unit” (2131) and a “content use unit” (2132).

  The “use bridge media holding unit” (2131) has a function of holding the bridge media holding the content recorded in the third bridge media recording / holding unit (2122) of the electronic device (2120). With this function, the content already recorded on the bridge media can be used by the content using unit described later. That is, the electronic device (2120) does not directly use the content.

  The “content using unit” (2132) has a function of using the content held in the bridge medium held in the used bridge medium holding unit (2131). The method of use is not particularly limited, but it is conceivable that the content is mainly reproduced.

  Further, the configuration of the content use system shown in FIG. 22 is different from the configuration of the content use system shown in FIG. 21 in that the charging processing section (2211) of the portable communication terminal (2210) includes a “charging identification information holding unit” ( 2214). The function of the charging identification information holding means (2214) is the same as that of the second embodiment.

  Further, in the configurations shown in FIGS. 21 and 22, the electronic device may have a memory as appropriate. That is, a memory may be provided between the transfer content receiving unit and the third bridge media recording and holding unit, and the received content may be temporarily buffered in the memory and then recorded on the bridge media.

  <Specific example of Embodiment 3>

  A specific example of this embodiment will be described. 23 and 24 show an example of a specific example.

  The content use system shown in FIG. 23 has a basic configuration in the present embodiment, and the content use system shown in FIG. 24 is based on the content use system of FIG. .

  First, FIG. 23 will be described in detail. It is assumed that the mobile communication terminal (2310) has downloaded, for example, the content “Rion Heart” by the content receiving unit (2312). In the charging processing unit (2311), processing for charging is performed by the downloaded content “Rion Heart”. Is transmitted. The content “Rion Heart” downloaded by the content receiving unit (2312) is transferred to the outside by the content transfer unit (2313). The transfer destination does not necessarily have to be the electronic device (2320), but it is assumed here that the transfer has been made to the electronic device (2320). The electronic device (2320) receives the content “Rion Heart” transferred from the content transfer unit (2313) of the mobile communication terminal (2310) by the transfer content receiving unit (2321). Thereafter, the content “Rion Heart” is recorded by the third bridge media recording and holding unit (2322). The bridge media in which the content “Rion Heart” is recorded is held by the use bridge media holding unit (2331) of the content use device (2330), and the recorded content “Rion Heart” is stored in the content use unit (2332). It is used by being reproduced.

  The difference between the content use system shown in FIG. 24 and the content use system shown in FIG. 23 is that the billing processing unit (2411) of the portable communication terminal (2410) has a billing identification information holding unit (2414). This is a point in which the processing method of the accounting processing unit (2411) is different, and this point will be described in detail.

  In the billing processing unit (2411), assuming that billing identification information holding means (2414) holds billing identification information, for example, identification information "A20345", this identification information and the downloaded content "Rion Heart" are stored. For example, a process for transmitting a message such as "Debit the mobile terminal A20345 download fee of 1000 yen from the bank account of the content service provider contract" is performed.

  <Process Flow of Third Embodiment>

  FIG. 25 illustrates an example of a processing flow in the third embodiment. The processing in the present embodiment includes the following steps.

  First, the content is downloaded (content download step S2510).

  Next, processing for charging based on the content downloaded in the content downloading step (S2510) is performed (charging processing step S2520).

  Next, the content downloaded in the content download step (S2510) is transferred (content transfer step S2530).

  Here, the order of the charging process step (S2520) and the content transfer step (S2530) may be reversed. The above steps are processing in the portable communication terminal.

  Next, the content transferred in the content transfer step (S2530) is received (transferred content reception step S2540).

  Next, the content received in the transfer content receiving step (S2540) is recorded on the bridge media (bridge media recording step S2550).

  As described above, steps S2540 and S2550 are processing in the electronic device.

  Next, the bridge media on which the content is recorded in the bridge media recording step (S2550) is held in the content using device (bridge media holding step S2560).

  Finally, the content recorded on the bridge media held in the bridge media holding step (S2560) is used (content using step S2570).

  As described above, step S2560 and step S2570 are processes in the content use device.

  <Effect of Embodiment 3>

  As described above, according to the content utilization system of the present embodiment, it is possible to download a content composed of one or a plurality of data by a portable communication terminal and transfer the content to an electronic device by infrared rays or the like. Further, the electronic device can hold the received content data by holding the bridge media. For example, the electronic device can transfer the data to a plurality of electronic devices and reproduce the data. Further, since the content using apparatus can also hold the bridge medium, for example, the content data can be used by reading the content data recorded on the bridge medium from the bridge medium in the electronic device. Furthermore, in the content usage system of the present embodiment, since only the mobile communication terminal downloads the content directly from the content server, there is no need to make a content contract for each device that uses the content. Payment of expenses and the like can be simplified.
