  The management server 55 has a charging function for a user based on the download log information registered in the storage device 555 and a function for registering and managing account information sent from the mobile phone device 1. Then, billing processing based on the download log information is performed according to the account information. This billing process includes processes such as credit settlement and invoicing.

  Next, the operation of the present invention will be described with reference to a flowchart. First, a method for downloading content to the mobile phone device 1 will be described with reference to FIG. The downloading method is not limited to this, and the method shown in FIG. 7 is merely an example.

  The mobile phone device 1 is equipped with a program execution environment (Java virtual machine) created in the Java (registered trademark) language, and can execute application software created in the Java language. In this cellular phone device 1, as one of application software, a program for downloading content and a control program for transmitting the downloaded content to the content using electronic device (sound source playback device) 2 are downloaded from a server or the like and executed. It is configured to be able to.

  First, the user (orderer) accesses the content sales homepage established on the Internet 46 by the content service provider via his mobile phone device 1 (step S1). In response to this, the content providing server 50 transmits an account registration screen to the mobile phone device 1 (step S2). On the display screen 11 of the mobile phone device 1, an account creation screen showing an ID, a password, a mobile phone number, a phone number, a name, an address, a settlement method, and the like is displayed. The orderer inputs account information from the user portable terminal 10. (Step S3).

  When the account information thus created is transmitted, the content providing server 50 registers the account information as user information in the storage unit 505 (step S4). Then, the management server 30 creates a new account as customer management data (step S5), and sends registration confirmation information to the content providing server 50 (step S6).

  When the content providing server 50 receives the registration confirmation data, the content providing server 50 transmits a content menu screen showing the content type and the like to the mobile phone device 1 (step S7).

  Next, when the user selects the desired content and specifies download (step S8), the specified content is downloaded from the content providing server 50 to the mobile phone device 1 (step S9). The cellular phone device 1 stores the downloaded content in the memory unit 17. When the download is completed, a download completion notification is transmitted from the mobile phone device 1 to the content providing server 50 (step S10). Then, the mobile phone device 1 ends the download operation. The download log is temporarily stored in the content providing server 50.

  Next, the content providing server 50 transmits a download log to the management server 55 (step S11). Then, the content distribution operation ends.

  When the management server 55 receives the download log, the management server 55 performs billing processing based on the price information designated in advance by the content provider based on the log information. Billing data for each customer is created based on the accounting data and the account information held by the management server 55, and the operation is terminated (step S12). The billing data includes account information, billing destination, downloaded file name, date and time, billing amount, and settlement method. Further, the management server 55 can display the billing data with a web function, and the user can confirm his billing data based on the ID and password.

  Next, the operation of the embodiment of the present invention will be described with reference to the flowcharts of FIGS. FIG. 8 is a flowchart showing an operation when content data downloaded from the content providing server 50 to the mobile phone device 1 is transmitted to the sound source playback device 2 side, FIG. 9 is a flowchart showing a communication connection processing routine, and FIG. It is a flowchart which shows a transmission management process routine.

  As shown in FIG. 8, based on the operation shown in FIG. 7, the content preferred by the user is downloaded from the content providing server 50 to the mobile phone device 1 (step S20). The sound source playback device 2 is in a state of waiting for content reception (step S21). When content is downloaded from the content providing server 50 to the mobile phone device 1, the content providing server 50 sends information that restricts the mode of use of the content. In this embodiment, the effective number of days for which the content can be used, the number of erasing days for erasing the content, and the number of transfer permits that can be transferred to the sound source playback device 2 are determined. Therefore, in the mobile phone device 1, after downloading the content, the effective days for the content is recorded in the memory unit 17 (step S22). In the mobile phone device 1, processing such as the number of effective days is grasped using a built-in calendar function or the like. Subsequently, the cellular phone device 1 records the erasure days after downloading the contents in the memory unit 17 (step S23). In this embodiment, when the transferable number of times has not been reached even after the effective number of days has elapsed, the transfer is possible. For this reason, the number of days that is more than twice the effective number of days is set as the elimination day. When the number of deletion days is reached, control is performed so that the target content downloaded and stored from the memory unit 17 is deleted and the content cannot be used.

  Then, the number of times transfer is permitted, which is the number of times that the mobile phone device 1 can transfer to a different sound source playback device 2, is recorded in the memory unit 17 (step S24). As described above, when content is downloaded from the content providing server 50, information that restricts the usage mode of the content is recorded in the memory unit 17.

  In the case where data downloaded by the user to the mobile phone device 1 is transmitted to the sound source reproduction device 2 by infrared communication in accordance with the IrDA standard, the mobile phone 1 is operated to perform the infrared communication connection. When connection to the playback device 2 is requested, the communication connection processing routine is entered (step S25).

  When the communication connection processing routine is entered, the cellular phone device 1 performs the operation shown in FIG. First, the cellular phone device 1 reads the corresponding content deletion days from the memory unit 17, and determines whether or not the deletion days have passed (step S251). If it is determined in step S251 that the number of erasure days has elapsed, there is no data to be transferred, so that information is displayed on the liquid crystal display unit 11, and the transfer operation is terminated. Therefore, when the number of deletion days is reached, transfer to the sound source reproduction device 2 cannot be performed even if the transfer count remains.

  On the other hand, if the deletion days have not elapsed, the process proceeds to step S252, and it is determined whether the effective days have elapsed. If it is determined in step S252 that the effective days have passed, the process proceeds to step S254.

  In step S254, it is determined whether the number of transfers is zero. If the number of transfers is 0, the content has never been used since downloading. In this case, it is severe for the user to control the content so that it cannot be used immediately after the effective days have passed. Therefore, if the number of transfers is 0 even if the number of valid days has elapsed, transfer is permitted unless the number of deletion days has elapsed. Therefore, it progresses to step S256 and an infrared communication connection operation process is performed.

  In step S254, if the number of transfers is not zero, the process proceeds to step S255. If the same manufacturer, the same model (model ID), and the like have been downloaded once, the device can be downloaded again. For this reason, in step S255, it is determined whether or not the download is for the same device. If the same device is downloaded, the process proceeds to step S256 to perform an infrared communication connection operation process. If they are not the same device, a message indicating that transfer is not permitted is displayed on the liquid crystal display unit 11, and the transfer operation is terminated.

  On the other hand, if it is determined in step S252 that the effective number of days has not elapsed, the process proceeds to step S253, and it is determined in step S253 whether there is a transfer count. If there is a transfer count, the process advances to step S256 to perform infrared communication connection operation processing. If there is no transfer count, in step S255, it is determined whether or not the download is for the same device. If the same device is used, the process proceeds to step S256 to perform infrared communication connection operation processing. If they are not the same device, a message indicating that transfer is not permitted is displayed on the liquid crystal display unit 11, and the transfer operation is terminated.

  The presence / absence of the transfer count is configured such that, for example, when the transmission is successful and the permission count is decreased by one and becomes zero, it is determined that there is no transfer count. When the transmission count is decremented and becomes zero, it is determined that the permission is lost, or conversely, every time a normal transmission operation is performed, the number is incremented and the total number of times matches the number of permitted transmissions. You may comprise so that it may judge that the frequency | count of transmission permission is lost.

  In step S256, the sound source reproduction device 2 sets an operation so that infrared communication can be performed with the mobile phone device 1 by access from the mobile phone device 1, and infrared communication with the mobile phone device 1 is performed. Communication processing for establishing a connection is performed, and this routine is terminated.

  When receiving the communication setting process notification from the mobile phone device 1 side by the communication connection process (step S25), the sound source reproduction device 2 performs a process of establishing infrared communication and notifies the mobile phone device 1 to that effect (step S26). ).

  When the infrared communication connection is established, the user sends a data transmission request to the sound source reproduction device 2 in order to transmit content data from the mobile phone device 1 to the sound source reproduction device 2 (step S27). Information data to be sent in response to a data transmission request includes a data type, a data size, and a manufacturer code and a model ID as required.

  The sound source reproducing device 2 confirms the attribute of the transmitted information data (step S28). The sound source playback device 2 checks the attribute of the information data, and if the manufacturer code and model ID are set, the sound source playback device 2 reads the manufacturer code and model ID stored in the memory unit 222, These codes, IDs, etc. are collated to determine whether or not reception is possible. That is, if the collation result does not match, reception is not possible, and if it matches, reception is possible. Further, when reception is possible, the received data type and data size are acquired, and an area for receiving and recording communication data is secured. Thereafter, the attribute information of the sound source reproduction device 2 including the determination result of the reception availability and the serial number is sent to the mobile phone device 1 (step S29).

  In the cellular phone device 1, it is determined whether or not to transmit the content data based on the determination result of the reception availability sent from the sound source reproduction device 2 (step S 30). When reception is impossible, in order to stop transmission, infrared communication is forcibly terminated and the operation is terminated. As a result, downloading of content data to the sound source playback device 2 for which reception permission has not been obtained can be prohibited. Further, in the mobile phone device 1, it can be confirmed that the transmission is forcibly terminated, and the user can recognize that the content data cannot be transferred to the sound source reproduction device 2.

  On the other hand, when reception is possible, all data of the content data is transmitted to the sound source reproduction device 2 by packet communication. The content data is transmitted after being encrypted. Then, transmission record up information (device serial number and the like) to the server system 5 is provisionally registered (step S31).

  The sound source reproduction device 2 receives the content data sent from the mobile phone device 1 and decrypts the encrypted data (step S32). Subsequently, the reliability of the received data is checked by CRC to determine whether there is an error in the data. If there is no error, the compressed data is decompressed and stored in the data storage area of the memory unit 222 (step S30). Then, the determination result is sent to the mobile phone device 1, the communication is disconnected, and the operation is terminated.

  The cellular phone device 1 determines the communication determination result sent from the sound source reproduction device 2 (step S34), and in the case of an error, the communication is cut off and the operation is terminated. If data communication is normally performed without error, a transmission management process routine is entered (step S35).

  In this embodiment, the permitted number of transmissions from the cellular phone device 1 to the sound source reproduction device 2 is set in advance. When the transmission management processing routine is entered, as shown in FIG. 10, the number of times of permission is reduced by 1 due to successful transmission, and the value is written in the memory unit 17 (step S351). Subsequently, it is determined whether or not the number of times of permission has become zero (step S352). If the number of times of permission is not zero, the transmission management processing routine is terminated, and the communication is disconnected and the operation is terminated.

  Thereafter, the cellular phone device 1 accesses the server system 5 and transmits the temporarily registered transmission record update information (such as the serial number of the device) to the server system 5. As a result, the server system 5 can grasp the transmission record update information (such as the serial number of the device).

  On the other hand, if it is determined that the number of times of permission has become zero, the process proceeds to step S353, the content data stored in the memory unit 17 is erased, the transmission management processing routine is terminated, and the communication is terminated to terminate the operation. To do.

  This transfer permission count process is the same as the count process in the communication connection process S25 described above. That is, when the data transmission is completed normally, the transmission count is counted. As described above, when the transmission count is decremented and becomes zero, it is determined that the permitted number of times has been reached. In contrast to this process, each time a normal transmission operation is performed, the number of times may be incremented, and it may be determined that the number of permitted transmissions has been reached when the total number of times coincides with the permitted number of times of transmission.

  With the method described above, data such as music downloaded from the content providing server 50 can be transmitted to the sound source playback device 2. As a result, the sound source reproduction device 2 can reproduce the user's favorite music or the like.

  Data to be downloaded is not limited to music, but programs and the like can be downloaded, and version upgrades of programs such as the sound source playback device 2 can be used.

  The operation when the content data downloaded from the content providing server 50 to the mobile phone device 1 is transmitted to the sound source reproduction device 2 side has been described with reference to FIGS. According to the present invention, data from the host of the main body on the sound source reproduction device 2 side can be downloaded to the mobile phone device 1 by infrared communication. The data downloaded to the mobile phone device 1 can also be uploaded to the server system 5 or transferred from the mobile phone device 1 to other devices capable of infrared communication by infrared communication.

  The operation of downloading data from the host of the main unit on the sound source playback device 2 side to the mobile phone device 1 by infrared communication will be described with reference to FIG.

  As shown in FIG. 11, the mobile phone device 1 operates an application for performing data download operation on the sound source reproduction device 2 side (step S41). Data is acquired from the host of the data main body of the sound source reproduction device 2 and stored in the memory unit 222 (step S42).

  Subsequently, the user operates the mobile phone 1 to request connection to the sound source playback device 2 in order to receive data between the mobile phone device 1 and the sound source playback device 2 by infrared communication conforming to the IrDA standard. (Step S43). Then, the sound source playback device 2 sets an operation so that infrared communication can be performed with the mobile phone device 1 by access from the mobile phone device 1, and an infrared communication connection is established with the mobile phone device 1. (Step S44).

  When the infrared communication connection is established, the user sends a data reception request to the sound source reproduction device 2 in order to receive data stored in the memory unit 222 from the mobile phone device 1 to the sound source reproduction device 2 (step S45). A manufacturer code and a model ID are sent as information data sent in response to a data reception request.

  The sound source reproduction device 2 confirms the attribute of the sent information data (step S47). The attribute of the information data is confirmed, and the sound source reproduction device 2 reads the manufacturer code and model ID stored in the memory unit 222, collates these codes and ID, and determines whether or not reception is possible. That is, if the collation result does not match, transmission is not possible, and if it matches, transmission is allowed. Further, when transmission is possible, information such as the type of data to be transmitted, the data size, and the serial number is set. Thereafter, the attribute information of the sound source reproduction device 2 including the determination result of the transmission permission / inhibition and the serial number is sent to the mobile phone device 1 (step S47). Then, the data to be transmitted by the sound source reproduction device 2 is encrypted and transmitted by packet communication (step S49).

  In the cellular phone device 1, it is determined whether or not to continue the reception based on the determination result of the transmission permission / inhibition sent from the sound source reproduction device 2 (step S <b> 48). If the reception is not continued, the infrared communication is forcibly terminated and the operation is terminated in order to stop the reception. As a result, downloading of data from the sound source playback device 2 for which transmission permission has not been obtained can be prohibited.

  On the other hand, if reception is possible, the data transmitted from the sound source reproduction device 2 by packet communication is received, and the encrypted data is decrypted (step S50). Subsequently, the reliability of the received data is checked by CRC to determine whether there is an error in the data. If there is no error, the compressed data is decompressed and stored in the data storage area of the memory unit 17 (step S51). Then, the determination result is sent to the sound source reproduction device 2, the communication is disconnected, and the operation is terminated.

  The sound source reproduction device 2 determines the communication determination result sent from the mobile phone device 1 (step S52). If an error occurs, the communication is disconnected and the operation is terminated. If data communication is normally performed without error, the data stored in the memory unit 222 is deleted and the process ends (step S53).

  In the embodiment of the present invention, the infrared communication function of the IrDA (Infrared Data Association) standard is used between the mobile phone device 1 and the sound source reproduction device 2, but the present invention is not limited to this, and the Bluetooth (registered trademark) standard is used. In addition, data can be transmitted and received using a wireless communication function such as a wireless LAN.

  In the above-described embodiment, the case of the mobile phone device has been described. However, the present invention can be applied to an information terminal device capable of performing a wireless communication function such as infrared communication of a personal computer, a mobile terminal, etc. in addition to the mobile phone device.
