When the mobile phone terminal 20 accesses the distribution service site provided by the distribution server device 10, the mobile phone terminal 20
(Step S1), the caller's telephone number is obtained (step S2), which is the same as the telephone number of the distribution service subscriber registered in the telephone number-specific billing destination data memory 12e. The member is authenticated (step S3).

In this member authentication, if the received mobile phone terminal 20 is authenticated as a member of the present distribution service, a list of various content names such as song titles and titles stored in the content name list memory 12b is obtained. The data is transmitted to the mobile phone terminal 20 (Step S4).

Then, in response to the transmission of the list of content names, when the content name desired by the terminal user is received from the mobile phone terminal 20 (step S5), the user further operates the mobile phone terminal 20 side. Either the designated data for receiving the data distribution as the designated content for exclusive use of the mobile phone or the designated data for receiving the data distribution as the content for general use is received (step S6).

Here, it is determined whether or not a user for mobile phone exclusive use has been designated (step S7). If it is determined that a user for mobile phone exclusive use has been designated, the mobile phone terminal 20 receives the message from the mobile phone terminal 20 in step S5. The data of the content corresponding to the received user-specified content name is read from the content data memory 12d, and the content of the user-specified content data is read in step S
By using the caller telephone number acquired in step 2 as a key and adding noise for preventing use of copy (copy use prevention information), use by devices other than the caller is prohibited (step S8).

Then, the user-specified content data to which the noise for preventing duplication use (duplication use prevention information) has been added in step S8 is transmitted to the portable telephone terminal 20 of the transmission source (step S9). .

If it is determined in step S7 that a user designation for general use has been received instead of a user designation for exclusive use of a mobile phone, the content data corresponding to the content name designated by the user is stored in the content data. It is read from the memory 12d and transmitted as it is to the originating mobile phone terminal 20 (step S
7 → S9).

Then, the fixed price of the distribution fee for the content transmitted to the portable telephone terminal 20 is read from the content-specific charging price memory 12c (step S).
10) In the case of data distribution for exclusive use of a mobile phone, a certain rate of discount is given because unauthorized use to a third party is reliably prevented (step S11 → S12).

For example, in the case where the fixed price of the distribution fee for one piece of music software is "300 yen" when data distribution is performed without adding noise for preventing duplication use (duplication use prevention information) specified by a user for general use. Is a discount rate [33%] for exclusive use of a mobile phone, and the distribution fee of one piece of the music software when the data distribution is added with noise for preventing duplication (duplication usage prevention information) is " 100
Yen ".

Then, the terminal user's bank account number corresponding to the caller's telephone number is read out from the telephone number-based charging destination data memory 12e, and the content data distribution destination user is charged at the fixed price or the discounted rate. (Step S13).

FIG. 5 is a flowchart showing a content receiving process in the portable telephone terminal 20.

When the mobile phone terminal 20 calls the distribution server device 10 to access the distribution service site provided by the distribution server device 10 (step A1), the distribution server responds to the call. Apparatus 1
After the member authentication with the registered telephone number is performed between the content server and the registered telephone number 0 (step A2), list data of various content names such as a song title and a title transmitted from the distribution server device 10 is received (step A3). Is displayed on the display unit 25 as a selection screen (step A4).

When a desired content name is designated by a user operation on the input section 27 on the content name selection screen, data of the designated content name is transmitted to the distribution server device 10 (step A).
5).

Then, a user use mode selection screen for selecting whether to receive data distribution as content exclusively used for the mobile phone or data distribution as general content is displayed on the display unit 25 (step A6). When one of the use forms is selected and designated on the screen by a user operation on the input unit 27, the designated data is transmitted to the distribution server 10 (step A7).

Then, when the content data corresponding to the content name specified by the user is the mobile phone exclusive use specification, the distribution server device is added with noise for preventing copy usage (copy use prevention information). 10, and in the case of the general use designation, is received from the distribution server device 10 without adding the noise (step A <b> 8).

The user-specified content data received from the distribution server device 10 is stored in the music data memory 22e or the video data memory 22f in accordance with the type of the content (step A9).

When the distribution server device 10 completes the charging of the distribution fee for the terminal user's bank account, a notification of the completion of the charging process is received and displayed on the display unit 28 (step A10).

Here, when the content to which the noise for duplication prevention (duplication use prevention information) is added is received in accordance with the mobile phone exclusive use designation in step A6, the content is discounted at a predetermined discount rate. In the case where the user is charged for the distributed distribution fee, and the content without the duplication prevention noise (duplication usage prevention information) is received in accordance with the general use designation, a predetermined fixed price is applied. A delivery fee is charged to the user.

FIG. 6 is a flowchart showing a content use process in the portable telephone terminal 20.

According to the content receiving process of the portable telephone terminal 20 in FIG. 5, the music data memory 22e
When the operation for reproducing the data of the content is performed in the input unit 27 in a state where the content specified by the user is stored in the video data memory 22f, the content data designated for reproduction is stored in the data memory. (22e
Or 22f) (step B1),
It is content data to which noise for copy use prevention (copy use prevention information) designated for mobile phone use is added or noise for copy use prevention (copy use prevention information) for general use designation is not added. It is determined whether the data is content data (step B2).

Here, if it is determined that the content data is the content data to which the copy use prevention noise (copy use prevention information) designated for the mobile phone exclusive use is added, the content data dedicated to the mobile phone terminal 20 is used. , That is, content data using the telephone number of the own terminal stored in the mobile telephone number memory 22d as a key for noise cancellation (step B2 → B3).

Here, the content data is not exclusive to the mobile phone terminal 20, that is, the mobile phone number memory 2.
If it is determined that the content data is not the content data using the telephone number of the own terminal stored in 2d as a key for noise cancellation, the process proceeds to error processing, and an error message indicating that the content data cannot be reproduced is displayed. (Step B3 → Error processing).

On the other hand, the content data is exclusive to the user's own mobile phone terminal 20, that is, the mobile phone number memory 22d
If it is determined that the content data uses the telephone number of the own terminal stored in the terminal as a key for noise cancellation, the copy use prevention added to the content data based on the mobile phone number of the own terminal is used. (Reproduction prevention information) is removed, and the data is decoded into a data state usable by the AV playback device (step B3 → B4).

Thus, if the reproduction-designated content is music software, the content is reproduced and output from the speaker 29,
If the software is video software, the image data is reproduced and displayed on the display unit 28, and the audio data is reproduced and output from the speaker 29 (step B5).

On the other hand, in step B2, the content data designated to be reproduced and selectively read from the data memory (22e or 22f) is used for the copy use prevention noise (copy use prevention information) designated for general use. If it is determined that the content data is not added, the content data is in a data state usable by the AV playback device as it is, and if it is music software, it is reproduced and output from the speaker 29. In the case of video software, the image data is reproduced and displayed on the display unit 28, and the audio data is simultaneously output from the speaker 29.
(Steps B2 → B5).

FIG. 7 is a flowchart showing a content transmission process in the portable telephone terminal 20.

In the portable telephone terminal 20, the music data memory 22 is stored in accordance with the content reception process (see FIG. 5).
e and the user-specified content is stored in the video data memory 22f, and when the user wants to transfer the data of the content to the nearby AV reproduction electronic device 30 for reproduction, an operation for transmitting the content is performed. Input unit 2
7, the content data designated to be transmitted is selectively read from the data memory (22e or 22f) (step C1), and the noise for preventing the use of duplication of the mobile phone exclusive use designation (duplication use) It is determined whether the content data is the content data to which the copy prevention information has been added, or the content data to which the copy use prevention noise (copy use prevention information) designated for general use is not added (step C).
2).

Here, the transmission-designated content data selectively read from the data memory (22e or 22f) is added with the duplication use prevention noise (copy use prevention information) designated for general use. If it is determined that the content data does not exist, the content data is in a data state that can be used as it is in any AV playback device (copying is available), so that the process is shifted to error processing and the transfer is prohibited. Then, an error message indicating that the content data cannot be transmitted is displayed (step C2 → error processing).

On the other hand, the content data selectively read from the data memory (22e or 22f) specified to be transmitted is added with a noise (duplication use prevention information) for preventing use of duplication designated for use exclusively for a mobile phone. If it is determined that the content data is the content data, the short-range communication unit 26 is connected for communication with the AV reproduction electronic device 30 near the mobile phone terminal 20 (step C2 → step C2).
3), the content data to which the noise for preventing duplication use (duplication use prevention information) is added is transmitted (step C4).

FIG. 8 is a flowchart showing a content receiving process in the AV reproduction electronic device 30.

In order to receive the content data to which the noise for duplication prevention (duplication use prevention information) is added, which is transferred in accordance with the content transmission processing (see FIG. 7) in the portable telephone terminal 20, the nearby AV reproduction is performed. In the electronic device 30, when a reception operation is performed by the input unit 37, the short-range communication unit 36 causes the AV playback electronic device 3

Then, the content data to which the noise for preventing duplication use (duplication use prevention information) transmitted from the portable telephone terminal 20 is added is received via the short-distance communication unit 36 (step D2), and the music is received. If it is software content data, it is stored in the music data memory 32e, and if it is video software content data, it is stored in the video data memory 32f (step D3).

FIG. 9 is a flowchart showing a content use process in the AV reproduction electronic device 30.

When an operation for reproducing the content data stored in the music data memory 32e or the video data memory 32f is performed on the input unit 37, the content data designated for reproduction is stored in the data memory (32e or 32e).
f) (step E1), the content data is added with noise (duplication use prevention information) for preventing use of duplication designated for exclusive use of a mobile phone, or is the content data designated for general use designation. It is determined whether or not the content data is content data to which no use noise (duplication use prevention information) is added (step E2).

Here, when it is determined that the content data is the content data to which the noise for duplication prevention (duplication use prevention information) designated for exclusive use of the mobile phone is added, the short-range communication unit 36 makes the relevant AV reproduction electronic device. Communication connection is established with the mobile phone terminal 20 near the device 30 (step E2 → E
3).

In this short-range communication connection process, if it is determined that there is no communication terminal (20) that can be connected near the communication terminal, the process proceeds to an error process, and an error message indicating that reproduction is impossible is displayed on the display unit 38. (Step E4
→ Error handling).

On the other hand, in the short-range communication connection processing,
When a communication connection is established with a nearby mobile phone terminal 20, the terminal phone number is obtained from the mobile phone terminal 20 and stored in the short-range mobile phone number memory 32d (steps E4 → E5).

Then, the reproduction is designated and the memory (32
e or 32f), the content data to which the noise for duplication prevention (duplication use prevention information) of the mobile phone exclusive use designation is added is stored in the nearby mobile phone terminal 2.
It is determined whether or not the content data uses the terminal telephone number acquired from 0 as a key for noise cancellation (step E).
6).

Here, when it is determined that the content data read and designated for reproduction is not content data using the terminal telephone number obtained from the nearby mobile telephone terminal 20 as a key for noise cancellation, Is shifted to error processing, and an error message indicating that the content data cannot be reproduced is displayed (step E6 → error processing).

On the other hand, when it is determined that the content data read and designated for reproduction is content data using the terminal telephone number obtained from the nearby portable telephone terminal 20 as a key for noise cancellation, Based on the telephone number of the mobile telephone terminal 20 connected to the short-range communication, the noise (duplication use prevention information) added to the content data for preventing the use of the copy is removed, and the data state becomes usable for the AV playback device. It is decrypted (step E6 → E
7).

Thus, when the reproduction-designated content is music software, the content is reproduced and output from the speaker 39,
If the software is video software, the image data is reproduced and displayed on the display unit 38, and the audio data is reproduced and output from the speaker 39 (step E8).

That is, in the mobile phone terminal 20, the content data added with the copy use prevention noise (copy use prevention information) distributed and purchased from the distribution server device 10 by designating the dedicated use for the mobile phone is transferred to the short distance. When the portable telephone terminal 20 that has purchased and transferred the content data is transferred to the nearby AV playback electronic device 30 through a communication connection and is to be played back with good quality voice or image, the AV playback electronic device 30 Only in a nearby environment, the noise for preventing the use of duplication added to the content data can be removed, and high-quality audio and images can be reproduced by the AV reproduction electronic device 30.

On the other hand, in the step E2, the content data designated to be reproduced and selectively read from the data memory (32e or 32f) is the content to which the noise for copy use prevention designated for general use is not added. If it is determined that the data is data, the content data is in a data state that can be used as it is in an AV playback device. In some cases, the image data is reproduced and output from the display unit 38, and at the same time, the audio data is reproduced and output from the speaker 39 (steps E2 to E8).

According to the content distribution service system using the mobile phone terminal 20 and the AV playback electronic device 30, the mobile phone terminal 20 distributes content data such as music and video to the distribution server device 10 by specifying dedicated use for the mobile phone. When there is a request, the distribution server device 10 adds noise (duplication use prevention information) to the requested content data for preventing the use of duplication using the mobile phone number of the request source as a key. Since the content data is distributed only as the content data that can be used only by the telephone terminal 20, the price of the regular price (distribution fixed price) for distributing the content data to which the noise for preventing duplication use is not added by the designation of general use is reduced. On the other hand, a discounted and inexpensive usage fee can be set, and more users can purchase and use it. .

According to the content distribution service system including the distribution server device 10, the mobile phone terminal 20, and the AV playback electronic device 30 having the above-described configuration, the mobile phone terminal 2
0 is the content data to which the noise for preventing duplication use added and distributed and purchased with the mobile phone exclusive use designation is assigned to A.
When transferring to the V playback electronic device 30 for use,
The playback electronic device 30 removes noise for preventing duplication use added to the transferred content data based on a mobile phone number obtained from the same mobile phone terminal 20 through short-range communication connection, and plays back. Because
When the content data is played back by the AV playback electronic device 30, the mobile phone terminal 20 that purchased the content data needs to be present nearby, and unauthorized use by anyone other than the terminal user can be prevented. . Therefore, similarly to the above, it is possible to set a discounted inexpensive usage fee to a fixed usage fee (delivery fixed price) in the case of distributing the content data to which the duplication prevention noise is not added by designating general use, More users can be purchased and used.

In the present embodiment, the communication terminal is the portable telephone terminal 20, and the other communication terminal that performs short-range communication with the communication terminal is the AV terminal.
