Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a player terminal and a content data transmission system, and more particularly to a player terminal capable of copying between player terminals while protecting the privacy of a transmitting terminal and satisfying a private recording right. And a content data transmission system.

[0002]

2. Description of the Related Art With the recent development of the Internet and communication technologies, various music distribution systems have been proposed and realized. For the purpose of protecting the copyright of a composer or lyricist, this kind of music distribution system has strong copyright protection measures to prevent music data downloaded once from a music site on the Internet from being copied to others, for example.
In many cases, copying itself is not possible.

[0003] On the other hand, a system has been proposed in which instead of allowing copying of music data, a copyright fee can be charged for each copy.

In this type of system, a user inserts an IC card and a player or a memory card into a kiosk terminal installed in a record store or the like and pays a copyright fee in advance.
The charge information is stored in an IC card or the like, and the music data is downloaded to a player or a memory card.

[0005] That is, an IC card (for example, a prepaid card) in which numerical data corresponding to several times of copy charges are stored in advance, and this is purchased together with a reproducing machine or a memory card and installed in a kiosk installed in a record store. Set it on the terminal. Thereby, the music data stored in the kiosk terminal is downloaded to the player or the memory card, and the numerical data of the IC card is subtracted.

In order to listen to the downloaded music data, an IC card is inserted into a playback device for playback.

On the other hand, when copying music data downloaded to a memory card or a reproducing apparatus to another reproducing apparatus,
A per-copy billing method has been used. There are various types of charging methods for each copy, but a simple method is to subtract the copyright fee from the charge information charged to the IC card for each copy. In other words, copying was completed until the price finally reached 0 yen.

[0008] Another charge method for each copy is that, when a terminal of a copy source (transmission source) and a terminal of a copy destination (reception destination) are close to each other (a voice reaches), the copy destination becomes the copy source. After giving the voice of the copy request, the copy source terminal sends the requested music data to the copy destination terminal,
The copy destination terminal downloads the transmitted music data and downloads the downloaded music data until the downloaded music data is charged (notified to the charging center by notifying that the purchased copy music is purchased). In recent years, a method of preventing reading of a copied music has been developed.

[0009] That is, the copy-based charging method has a strong copyright protection measure so that music data is not illegally copied to another person.

[0010]

The above-described billing system for copying music data at a kiosk terminal as described above is based on the premise that a user goes to and copies the music data. So there is no problem.

[0011] However, strong copyright protection measures have been taken to prevent once downloaded music data from being copied to others, and the copy prohibition method, which makes copying impossible, has been infringed on private recording rights previously possible. It is also said to be.

[0012] Therefore, in the case where the above-described other charging method for each copy is performed, copying between users can be performed while protecting the copyright for many generations. Since copying is possible only when there is a copy source and a copy destination, if the copy source and the copy destination are remote, the voice cannot reach and the copy cannot be made.

That is, when the copy source and the copy destination are remote, even if the copy source wants the copy source to copy (private recording right), the copy destination cannot be copied. There was a problem that the rights could not be satisfied.

On the other hand, when a portable personal computer or the like is used, copying is possible even if the copy source and the copy destination are remote. However, since the apparatus is large and requires other communication equipment, etc.,
There is a problem that it is not easy to download music data while protecting copyright (also called security) outdoors.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and a player terminal and content data transmission capable of easily downloading content data while ensuring security even when a copy source and a copy destination are at remote points. The aim is to get the system.

[0016]

In order to solve the above problems, a player terminal according to a first aspect of the present invention is a player terminal having a portable telephone function, wherein the player terminal has a function of communicating with an opponent using the portable telephone function. Means for presetting the source telephone number and the personal identification number of the terminal obtained and input by the mobile phone function as call setting acceptance determination information when the terminal becomes a receiving destination by communication; and Means for authenticating whether or not the call setting information matches the call setting acceptance determination information when the call setting information by calling from the transmission source is received after setting the reception determination information; and When they match, after sending notification of the call setting acceptance to the transmission source, means for copying the content data transmitted from the transmission source to the memory is provided.

In the player terminal according to the first aspect of the present invention, communication with the other party is performed by using the mobile phone function, and when the terminal becomes a destination of the content data, the content data is obtained by the mobile phone function. Authenticates whether the set call setup acceptance determination information matches the call setup information from the sender, and notifies the sender of the call setup acceptance only when the information matches, and then the By copying the transmitted content data into the memory, the content data cannot be received unless the telephone number of the transmission source obtained by the mobile phone function and the personal identification number of the terminal are set as call setting acceptance determination information. I have to.

Therefore, conventionally, if it becomes possible to view the contents of the transmitting terminal by calling from the receiving terminal, the owner of the transmitting terminal may change a file name that the user does not want to show to others. Although extra work has been forced, the player terminal according to the present invention only needs to be able to transmit the file specified by the sender, and the above work is unnecessary. In the unlikely event that this procedure is hacked, the player terminal according to the present invention only automatically transmits the data specified by the transmitting side, and does not have a procedure to enter the partner system and transmit the user command. Therefore, it is possible to prevent a situation in which the receiver enters the transmission side system and an illegal process is performed. As a result, privacy protection in the transmitting terminal can be achieved.

Further, when the terminal becomes a transmission source by the communication by the mobile phone function, the player terminal obtained and input by the mobile phone function is provided. Means for presetting a personal identification number as the call setting information, and means for, when a content name to be copied to the destination is input, setting the content name in advance as a content name to the destination, Means for transmitting the call setting information when the call setting information and the content name are set, and connecting the line to the reception destination; and receiving the call setting from the reception destination after the line is connected to the reception destination. And a means for sequentially reading out the content data of the content name when receiving the notification of the above, and transmitting the content data as content data to be copied.

In the player terminal according to the second aspect of the present invention, when the terminal is the transmission source, the personal identification number of the reception destination obtained and input by using the mobile phone function is used as the call setting information. As long as the password and the content name of the recipient obtained by the mobile phone function are not set, by setting and sending as well as connecting the line with the recipient and transmitting the content data corresponding to the set content name , Content data cannot be transmitted. The content name used here is not limited to a simple name, but is used in a broad sense including a code as identification information. Therefore, it is possible to transmit content data while protecting privacy.

A content data transmission system according to a third aspect of the present invention is a content data transmission system in which player terminals having a cellular phone function are used by being located at remote points with respect to each other. Communicates with the other party using the respective mobile phone functions, and when the other party wants to copy the content data, it becomes the transmission source, and the transmission source is the personal identification number of the reception destination and the reception destination requests. The content name is obtained and set in advance, and the reception destination obtains the telephone number of the transmission source and sets it in advance as the call setting acceptance determination information together with the password of the terminal, and the transmission source sets the password in the After transmitting the call setting information to the reception destination, when the reception of the call setting is notified from the reception destination, the content data of the content name is transmitted. Sequentially, the reception destination notifies the call setting reception when the call setting information transmitted by the call from the transmission source and the set call setting reception determination information match, The gist is to sequentially copy content data from a transmission source to a memory.

In the content data transmission system according to the third aspect of the present invention, the transmission source sets the personal identification number and the content name of the destination obtained by using the mobile phone function, while the reception destination is the mobile phone. The source telephone number obtained by the telephone function is set as call setting acceptance determination information together with the personal identification number of the terminal. Then, after transmitting the personal identification number of the receiver as the call setting information to the receiver, the receiver sequentially transmits the content data of the content name when the receiver receives the call setting, while the receiver is When the call setting information from the call originating from the transmission source matches the predetermined call setting reception determination information, the call setting reception is notified, and the content data from the transmission source is sequentially copied to the memory.

Therefore, the effect is obtained that the content data can be copied between the player terminals located at remote points from each other while protecting the privacy of the transmitting terminal. As a result, infringement of the private recording right in downloading the content data can be prevented.

[0024]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with music data as content data. Also, a content data transmission system for copying music data from a copy source (transmission side) music player terminal to a copy destination (reception side) music player terminal according to the present embodiment will be described as a music data transmission system.

The baseband signal processing unit 104 further controls the display unit 105 to display the telephone number of the communication partner terminal. In addition, the name of the music data stored in the memory card 11 is displayed.

The codec 106 intervenes between the baseband signal processing unit 104 and the transmission / reception unit 107 to perform ADPCM encoding / decoding of a voice signal in a voice communication mode.

An EEPROM (Electrically Erasable and
The programmable ROM 108 has, via the operation unit 109, a password M unique to the terminal itself and identification information Mus indicating that the transmitted content is music data.
ic is set and stored. When the terminal is on the transmitting side, the password M of the receiving side terminal is set and stored. On the other hand, when the terminal is on the receiving side, the telephone number H of the transmitting side terminal is set and stored. Normally, the password M of the terminal itself and the identification information Music are not once set and then rewritten. On the other hand, the password and the telephone number are appropriately rewritten.

The CPU (computer) 110 controls data transfer in the baseband signal processing unit 104 in the voice communication mode, and authenticates a communication partner in the music distribution mode. An SRAM 111, a memory controller 112, and a decoder 113 are connected to the CPU 110 via a data bus. SR
The AM 111 functions as a buffer that speeds up data processing between these elements.

The memory controller 112 is a CPU
According to the instruction from 0, the writing / reading operation of the music data to / from the memory card 11 is managed. At the time of writing / reading, the music data is encrypted / decrypted using the key (key information) stored in the memory card 11. This key is desirably the telephone number or password of the destination terminal 1a.

The memory card 112 is connected to the memory controller 112. The music data is stored in the memory card 11. The input / output of the music data is managed by a controller (not shown) in the memory card 11.

The decoder 113 expands the compressed music data and converts it into an analog audio signal. Also, the decoder 113 amplifies the analog signal from the decoder 113 and amplifies the speaker or headphones (both not shown).
Is connected to an audio unit 114 that outputs the audio signal.

FIG. 3 is a diagram showing a configuration of a program stored and executed in the CPU 110 together with some hardware.

In this embodiment, by executing a program, a call acceptance determination processing unit 51, a music selection information transfer processing unit 52, a music data processing unit 53, an automatic line disconnection / connection instruction processing unit 54, and a data reproduction instruction processing The unit 55 is configured. These processing units operate when the operation unit 109 is operated and “music distribution mode” is selected.

When the own terminal is the receiving side, the call acceptance determining processing unit 51 makes a three-stage determination on the predetermined information transmitted by the calling from the transmitting side, and the calling source terminal determines The mobile phone function authenticates in advance whether or not the terminal is a partner of the call.

That is, first, it is determined whether or not the transmitted telephone number matches the telephone number H of the partner terminal set in the EEPROM 108. Second, the transmitted security code is the security code M set in the EEPROM 108.
Is determined. Third, it is determined whether or not the transmitted information includes the identification information Music.

Hereinafter, the information transmitted to the receiving terminal by calling the transmitting terminal and the information such as the transmission speed and the protocol in the PHS communication (for example, 64
kbps unrestricted digital transmission, etc., hereinafter referred to as “communication setting information”) is collectively referred to as “call setting data (or call setting information)”. On the other hand, EEPROM1
08, and the information used for the authentication is referred to as “call setting acceptance determination information”. When the authentication is "OK", the call reception determination processing unit 51 controls the baseband signal processing unit 104 to send data (call setting reception) indicating that the call setting data has been received to the communication partner. Notice.

The music selection information transfer processing section 52 displays the music title (content data name) of the music data stored in the memory card 11 so that the user can select the music to be transmitted when the terminal is the transmission side. It is displayed on the unit 105. When a song is selected by operating the operation unit 109 by the user, song selection information corresponding to the song is stored in the memory card 11.
To memorize.

When the terminal itself is the receiving side, the music data processing unit 53 encrypts the music data input via the baseband signal processing unit 104 by controlling the memory controller 112, and encrypts the music data by controlling the memory controller 112. Write to.

When the terminal itself is the transmitting side, the music data processing section 53 reads out the music data based on the music selection information in the memory card 11 and transmits the read music data. Then, by applying a generator polynomial to the data in the transmitted frame, data for transmission error detection (hereinafter referred to as “CRC (Cyclic
Redundancy Check) data is calculated and stored, and this is compared with CRC data of the same frame returned from the receiving terminal to determine a transmission error. When there is a transmission error, retransmission of only the data is performed.

When the terminal itself is on the receiving side, the music data processing section 53 executes the CR for the received frame.
The C data is calculated and returned to the transmitting terminal.

When the terminal is on the receiving side, the line automatic disconnection / connection instruction processing section 54 connects the line when the authentication by the call acceptance determination processing section 51 is "OK". Becomes "NG" or when the music data processing unit 53 receives a notification that the reception of the music data has been completed normally, the line is automatically disconnected.

The automatic line disconnection / connection instruction processing unit 54
When the terminal is the transmitting side, the EEPROM 108
Then, the personal identification number and the identification information Music are read out, and the line with the receiving side is connected when the call setting acceptance is notified.

The data reproduction instruction processing unit 55 is
9 from the memory controller 112
To read the music data from the memory card 11 and reproduce it.

In the music data transmission system of the first embodiment, each music player terminal has the above configuration,
Then, as shown in FIG. 1, the transmitting terminal 1a obtains a password of the receiving terminal 1b obtained by a call with the receiving terminal 1b by the mobile phone function and is input by the user of the destination terminal 1a (hereinafter, the personal identification number of the receiving terminal 1b). Ma) and identification information Mu
sic is set in the EEPROM 108 in advance, and music selection information corresponding to the input music data obtained and input through a call using the mobile phone function is set.

When the automatic line disconnection / connection instruction processing unit 54 transmits the personal identification number Ma and the identification information Music prior to the copying of the music data, the telephone number Ha of the transmitting terminal 1a is added to the information, The call arrives at the receiving terminal 1b as call setting data.

On the other hand, in the receiving terminal 1b, the call setting acceptance determination information obtained by the mobile phone function and input by the user of the receiving terminal 1b, that is, the telephone number H, the password M and the identification information Music are also stored in the EEPROM 108.
Remember.

The call determination processing unit 5 determines whether the call setting information and the call setting reception determination information match each other.
1 and when the authentications match, the destination terminal 1a
To notify the call setting acceptance.

When the destination terminal 1a is notified of the call setting acceptance, the song data processing unit 53 reads the song data from the memory card 11 and sends it to the receiving terminal 1b. The music data processed is stored in the memory card 11 by the music data processing unit 53.

Next, a sequence of copying music data between terminals will be described with reference to FIG. First, an outline of this sequence will be described. The transmitting side terminal 1a and the receiving side terminal 1b communicate with each other using a normal mobile phone function.
The personal identification number or the like is obtained and set using the operation unit 109.
Further, the transmitting terminal 1a sets a song name, an identification number, and the like of the song to be copied by the receiving terminal 1b.

The telecommunications company that operates the public network 100 determines that the telephone numbers of the transmitting terminal 1a and the receiving terminal 1b and the data to be transmitted are music data from the call setting data of the transmitting terminal 1a and the receiving terminal 1b. To be able to authenticate.

Then, the receiving terminal 1b is
When the call setting data is received by calling from a, the contents of the data to be transmitted are music data, and the transmitting terminal 1
It is determined whether the telephone number and the password transmitted by the call from a coincide with those registered in advance. That is, the receiving terminal 1b checks whether the other party is the transmitting terminal 1a that is the copy source set using the above-described mobile phone function.

That is, it is confirmed that the content is not automatically downloaded from the content provider.

Only when the data to be transmitted is music data and the transmitted telephone number and password match those registered in advance, the receiving terminal 1b
Accepts the line connection with the other party (transmitting side) and connects. Thereby, the transmitting terminal 1a transmits the music data to the receiving side.

That is, in order to protect the privacy of the transmitting side, a call is made from the receiving side, which is the copy destination, to the transmitting side, which is the copy source, by using the mobile phone function to make a copy request. As a result, the transmitting party does not send the music data to the third party who does not want the copy to be made by the other party who made the copy request, so that the third party cannot copy.

On the other hand, if the caller is a person who can be copied, the sender informs the telephone number and the like and transmits the music data when the line connection is permitted from the receiver terminal. Prevents infringement of recording rights. In the copy from the transmission source, when the transmission source purchases the music data, the transmission fee is paid in advance for the copy.

Next, the sequence of FIG. 4 will be described in detail. In this sequence, prior to the copying of the music data, a call is made between the user of the transmitting terminal 1a and the user of the receiving terminal 1b, and information for connection with the communication partner terminal is registered in each terminal 1a / 1b. You.

That is, in the receiving terminal 1b, the telephone number H of the transmitting terminal 1a and the password M of the own terminal 1b are set (S1). Of course, this phone number H and the password M
Can be changed at any time even after registration.

After the registration is completed, the receiving terminal 1b is set to the music data distribution mode, and waits for data from the transmitting terminal.

On the other hand, the transmitting terminal 1a also selects the music to be transmitted, and sets the password Ma as the password of the receiving terminal 1b (S3).

When these pieces of information are set, a call control sequence between terminals is started. That is, step S
In step 5, when the telephone number of the receiving terminal 1b is input to the transmitting terminal 1a via the operation unit 109, a call is made, and at the same time, timer counting is started. Then, the call setting data is transmitted to the receiving terminal 1b (S7). The call setting data includes the communication setting information, the telephone number Ha of the own terminal 1a, and the security code M set as the security code of the receiving terminal 1b.
a. The communication carrier determines in step S7
Is monitored, and when the identification information Music is detected, it is determined that the communication fee is charged to the receiving side.

That is, in the first embodiment, the processing for directly requesting or selecting the music data in the transmitting terminal 1a is not performed from the receiving terminal 1b. Therefore, as described above, unauthorized copying of music data by a third party is prevented, and privacy protection on the transmission side can be achieved.

Referring back to FIG. 4, when the communication setting information is included in the call setting data, the receiving side terminal 1b executes step S9.
Performs the following determination processing, and authenticates whether the terminal 1a with which the call was made in advance using the mobile phone function is the caller.

That is, first, the call reception determination processing section 51 determines whether or not the transmitted telephone number Ha matches the telephone number H stored in the EEPROM (Ha = H). Second, the transmitted password Ma is stored in the EEPROM.
108 matches the password M of the terminal itself (M
a = M) is determined. Third, identification information Musi
It is determined whether or not c is included in the call setting data. First,
If the second and third determinations are all YES, the call setting acceptance is notified to the transmitting terminal 1a (S11). On the other hand, if any of the determinations is NO (does not match), the call setting acceptance is not notified.

The transmitting terminal 1a determines whether a call has been received before the time value of the timer reaches the predetermined threshold (S13), and determines that the call has not been received. If so, the process proceeds to step S59 to disconnect the line.

Next, the music data transmission sequence after the notification of the call setting acceptance will be described. The transmitting terminal 1a encrypts and compresses the music data of the memory card 11 using the personal identification number Ma, converts the data into a frame, and transmits the data (S21). The data is transmitted to the receiving terminal 1b (S23). The transmitting terminal 1a calculates and stores the CRC data of the transmitted frame (S25).

The receiving terminal 1b receives the framed music data, decompresses the data, and sets the personal identification number M of its own terminal 1b.
And store it in the memory card 11 (S2
7). As described above, the music data encrypted by the personal identification number Ma is decrypted by the personal identification number M. If these personal identification numbers do not match, the received data cannot constitute the music data, and the reproduction is also impossible. It will not be possible. After step S27, the receiving terminal 1b calculates CRC data of the transmitted frame (S29), and returns this to the transmitting terminal 1a (S31).

The transmitting terminal 1a checks the CRC data returned from the receiving terminal 1b against the previously stored CRC data (S33). Here, if they do not match, it is determined that a transmission error has occurred, and information for identifying the frame is stored in the SRAM 111. In addition,
These series of sequences are sequentially performed until the transmission of the music data ends.

Then, the transmission side terminal 1a determines that the data transmission is completed when the transmission of one piece of music data is completed (S
35), a data transmission end notification is transmitted to the receiving terminal 1b (S37).

Next, a music data retransmission sequence when a transmission error occurs will be described. If a transmission error is detected in step S33 of the music data transmission sequence, a frame corresponding to the error is retransmitted.

That is, the transmitting side terminal 1 a
The information for identifying the frame stored in the memory card 11 is read out, and based on the information, only the frame having an error is read out from the memory card 11, compressed and retransmitted (S4).
1), this data is transmitted to the receiving terminal 1b (S
43). The transmitting terminal 1a also stores the CRC data at the time of retransmission (S41).

The receiving terminal 1b erases the area (error portion) in the memory card 11 corresponding to the retransmitted frame, and writes and saves the data in the retransmitted frame (S45). Next, the receiving terminal 1b calculates the CRC data (S47) and returns (S49).

The transmitting terminal 1a checks the CRC data stored at the time of retransmission (S41) against the returned CRC data to determine whether there is a transmission error (S51).

The transmitting side terminal 1a checks the C in step S51.
When a transmission error is determined by comparing the RC data (S
53) retransmits the frame (S41).

On the other hand, when it is determined that there is no transmission error by checking the CRC data in step S51 (S55).
Transmits a data retransmission end notification to the receiving terminal 1b (S57).

When transmitting the data retransmission end notification, or when the determination in step S13 is NG, the transmitting terminal 1a transmits a disconnection request to the receiving terminal 1b (S59). Then, the receiving terminal 1b sends an open signal (S61). Thus, the copying of the music data between the users is completed.

Here, referring to the sequence diagram of FIG.
An application example of the first embodiment will be described. In this application example, the transmitting terminal 1a determines that the transmission is completed in step S35,
After transmitting the transmission end notification in step S37 (or S57), the personal identification number Ma of the receiving side terminal 1b is deleted (S37).
71). On the other hand, when receiving the data transmission end notification, the receiving terminal 1b deletes the telephone number H of the transmitting terminal 1a (S73). In this manner, by deleting the information used for the connection after copying the content, it is possible to prevent a situation in which the terminal is used by a third party without permission and the content is copied.

<Second Embodiment> Next, a second embodiment of the present invention will be described. FIG. 6 is a schematic configuration diagram of a music data transmission system to which Embodiment 2 is applied. In this system, as compared with the music data transmission system of FIG. 1, a content provider 2 for authenticating a terminal is provided on a public network 100.
(Distributor), and downloads to the copy destination via the content provider 2. Two types of download from the content provider 2 are provided: on-demand download and reservation download.

The on-demand download means that after a user calls a terminal to the content provider 2 for connection, the music selection menu information sent from the content provider 2 is displayed on the liquid crystal display of the music player terminal (PHS). Is a method for transmitting the selected content (music) in real time.

On the other hand, scheduled download means that when the line of the content provider 2 is busy and cannot be connected,
As in the case of on-demand download, music is selected from a reserved line held by the content provider 2 according to a menu, and then download reservation is registered to temporarily open the line.

Then, the reserved music is called from the content provider 2 to the user terminal when the distribution line is vacant, and is automatically downloaded after connection.

On the other hand, in copying between users, (1)
The user on the transmitting side and the user on the receiving side select music to be downloaded using their terminals in advance before copying.

(2) A call is sent from the transmitting terminal to the receiving terminal, and the transmitting user transmits the music selected in his / her memory card.

Since the music data is transmitted under the preconditions described above, and the music data is transmitted as if it were a mail, there is no operation of selecting a song in the memory of the terminal on the transmitting side while looking at the menu on the receiving side. .

In other words, since the owner of the music has the right to copy his / her own content to another person, it is possible to prevent another person from calling the copy source terminal and freely copying the internal contents. .

Returning to FIG. 6, the description of the second embodiment will be continued. The content provider 2 has a database DB in which the telephone numbers of the terminals (such as the terminals 1a / 1b) registered as user terminals of the system and the passwords of the respective terminals are registered and stored. Database DB
Stores identification information Music.

In this embodiment, the call setting data generated by the call from the transmitting terminal 1a does not directly reach the receiving terminal 1b, but is first transmitted to the content provider 2 via the public network 100. You.

FIG. 7 is a flowchart showing the flow of processing in the content provider 2. Upon receiving the call setting data (communication setting information, telephone number Ha, personal identification number Ma and identification information Music) and the telephone number (not shown) of the receiving terminal 1b, the content provider 2 first calls the telephone of the transmitting terminal 1a. The number Ha and the receiving terminal 1b
It is determined whether both telephone numbers are registered in the database DB (S81). If it is determined that both are registered (YES), the transmitted password M
It is determined whether or not a matches the password of the receiving terminal 1b registered in the database DB (S83). Here, when it is determined that they match (YES), it is next determined whether or not the call setting data includes the identification information Music (S85). Here, included (YE
If determined to be S), the call setting data is transferred to the receiving terminal 1b (S89), and the process is terminated. Subsequent operations are the same as in the first embodiment.

In the above embodiment, music data (song data) has been described as an example. However, it goes without saying that the transmitted content data may be image data or video data.

In the above embodiment, copying between music player terminals has been described. However, the transmitting side may be, for example, a computer (so-called content server) that stores and stores a large number of music data.

[0096]

As described above, according to the player terminal of the first aspect of the present invention, when the terminal becomes a receiving destination by communication with the opponent using the mobile phone function,
The call setting acceptance determination information of the transmission source obtained by the mobile phone function is set in advance.

That is, even if the player terminals are located at remote points, the condition for determining that the call is from the transmission source can be set.

[0098] Then, the receiving player terminal is
When the call setting information from the transmission source is received, and when these pieces of setting information match, the transmission setting is notified to the transmission source, and the content data transmitted from the transmission source is copied to the memory.

[0099] For this reason, even if the player terminals are located at remote locations, the content data from only the source is copied, and the privacy of the source can be protected. .

Further, even if the player terminal attempts to transmit contents from the player terminal to a third party terminal with malicious intent, the password of the other party must be known in advance, and the transmission side telephone number is stored in the EEPROM 108 in the other party terminal. Register the number,
In addition, reception cannot be performed unless the data reception mode is set, so that malicious transmission can be prevented.

According to the player terminal of the second aspect of the present invention, when the player terminal becomes a transmission source,
The call setting information of the receiving destination obtained by the mobile phone function and the content name desired by the receiving side are set in advance.

Then, the player terminal that has become the transmission source
This call setting information is transmitted to the receiving destination, and when receiving the call setting reception from the receiving destination, the content data of the set content name is sequentially transmitted.

For this reason, even if the player terminals are located at remote locations, the content data is copied only to the destinations permitted to copy using the mobile phone function.
Since the private recording right at the source can be secured and the content data at the source is charged,
The effect of privacy protection has been obtained.

According to the content data transmission system of claim 3 of the present invention, the player terminals first communicate with the other party using the mobile phone function. Then, the source player terminal presets the password and the content name of the destination, and the destination player terminal determines the telephone number of the source together with the password of the terminal in the call setting acceptance determination. It is set in advance as information.

After the personal identification number of the receiver and the telephone number of the sender are transmitted to the receiver as the call setting information, the sender transmits the content data of the content name when the call setting acceptance is notified. Send sequentially.

On the other hand, when the call setting information from the transmission source and the call setting acceptance judgment information match, the receiving destination notifies the call setting acceptance, and sequentially copies the content data to the memory.

For this reason, without requiring a large-sized device such as a personal computer or other communication equipment, it is possible to protect the copyright, that is, to ensure the security while ensuring that the content data can be exchanged between the remote player terminals. This makes it possible to easily download the file. As a result, infringement of the private recording right in downloading the content data can be prevented.
