(Pairing process)
FIG. 3 is a flowchart showing a pairing process executed by directly connecting the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B shown in FIG. As a premise for the following processing, the portable recording / reproducing apparatus 12A has its own electronic certificate Cm, public key Km, and private key Kp corresponding to the public key Km. Is assumed to have its own electronic certificate Cf, public key Kf, private key Kt corresponding to this public key Kf, and Internet connection information Lf for connection to the own device. The Internet connection information Lf here is, for example, an IP address or a MAC (Media Access Control address) address set in the fixed recording / reproducing apparatus 12B.

  The pairing process shown in FIG. 3 starts when the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B shown in FIG. 1 are directly connected. The portable recording / reproducing device 12A transmits its own electronic certificate Cm and public key Km to the fixed recording / reproducing device 12B (step S1).

  The fixed recording / reproducing apparatus 12B receives and stores the electronic certificate Cm and the public key Km transmitted from the portable recording / reproducing apparatus 12A in step S1 (step S2). Then, the fixed recording / reproducing apparatus 12B transmits its own electronic certificate Cf and public key Kf to the portable recording / reproducing apparatus 12A (step S3).

  The portable recording / reproducing apparatus 12A receives and stores the electronic certificate Cf and the public key Kf transmitted from the fixed recording / reproducing apparatus 12B in step S3 (step S4). Further, the fixed recording / reproducing apparatus 12B transmits Internet connection information Lf for connection to the own apparatus to the portable recording / reproducing apparatus 12A (step S5).

  The portable recording / reproducing apparatus 12A receives and stores the Internet connection information Lf transmitted from the fixed mold recording / reproducing apparatus 12B (step S6). After that, when the connection between the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B is disconnected, the pairing process ends (END).

  By the pairing process shown in FIG. 3, both parties have information (electronic certificate) specifying the other party and the other party's public key, and the subsequent mutual authentication process is possible.

(Authentication process)
After the pairing process of FIG. 3 is performed, the portable recording / reproducing apparatus 12A establishes a session between the two devices via the Internet 14, and thus can communicate with each other, and performs a mutual authentication process there.

  FIG. 4 is a flowchart showing an authentication process executed between the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B shown in FIG. In the authentication processing shown in FIG. 4, the electronic certificates Cm and Cf of the self are encrypted with the public keys Km and Kf of the other party and sent to the other side, and the secret keys Kp and Kt possessed by the self are received from the other side. Is decrypted to confirm whether or not the digital certificates Cm and Cf received during the pairing process are the same. Note that the authentication process shown in FIG. 4 is executed after the pairing process shown in FIG. 3 is performed, and the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B are connected to the Internet 14 and can communicate with each other. It is a precondition for the start (START) to be in a proper state.

  The portable recording / reproducing device 12A connects to the fixed recording / reproducing device 12B based on the Internet connection information Lf for connecting to the fixed recording / reproducing device 12B (step S11). When receiving the connection request from the portable recording / reproducing device 12A in step S11, the fixed recording / reproducing device 12B establishes communication with the portable recording / reproducing device 12A (step S12).

  When communication with the fixed recording / reproducing apparatus 12B is established, the portable recording / reproducing apparatus 12A encrypts the electronic certificate Cm of the own apparatus with the public key Kf of the fixed recording / reproducing apparatus 12B, and the encrypted electronic The certificate is transmitted to the fixed recording / reproducing apparatus 12B (step S13). Then, the fixed recording / reproducing apparatus 12B decrypts the encrypted electronic certificate transmitted from the portable recording / reproducing apparatus 12A with its own private key Kt (step S14).

  The fixed recording / reproducing apparatus 12B then decrypts the electronic certificate decrypted with its own private key Kt in step S14 and the electronic certificate received from the portable recording / reproducing apparatus 12A during the pairing process (ie, FIG. 3). The electronic certificate Cm) received in step S2 is compared to determine whether or not they match (step S15).

  If both electronic certificates match in step S15, the fixed recording / reproducing apparatus 12B sends its own electronic certificate Cf to the portable recording / reproducing apparatus 12A using the public key Km of the portable recording / reproducing apparatus 12A. The encrypted data is transmitted (step S16), and the authentication process on the fixed recording / reproducing apparatus 12B side is determined to be acceptable (step S17). On the other hand, if the two electronic certificates do not match in step S15, it is determined that the authentication process on the fixed recording / reproducing apparatus 12B side has failed (step S18), and the process is terminated (END).

  On the other hand, the portable recording / reproducing apparatus 12A determines whether or not the encrypted electronic certificate transmitted in step S16 is received from the fixed recording / reproducing apparatus 12B (step S19), and if it is determined that it has been received. The digital certificate is decrypted with its own private key Kp (step S20).

  The portable recording / reproducing apparatus 12A receives the electronic certificate decrypted in step S20 and the electronic certificate received from the fixed recording / reproducing apparatus 12B during the pairing process (that is, the electronic certificate received in step S4 in FIG. 3). Cf) to determine whether or not they match (step S21). The portable recording / reproducing apparatus 12A determines that the authentication is acceptable if they match by the comparison in step S21 (step S22), and determines that the authentication fails if they do not match (step S23). The process is terminated (END).

  In this way, the authentication unit, for example, exchanges information that can be uniquely recognized by each other in advance, and when two devices are connected via the Internet 14 after the exchange, the authentication unit recognizes each other based on the exchanged information. I can do it. In the authentication process shown in FIG. 4, the electronic certificate of the portable recording / reproducing device 12A is sent, and when the authentication is successful, the electronic certificate of the fixed recording / reproducing device 12B is sent. As shown in FIG. 5, the order is reversed (the electronic certificate of the fixed recording / reproducing device 12B is sent, and the electronic certificate of the portable recording / reproducing device 12A is sent when the authentication is successful). It may be. That is, you may make it become the process of step S13A-S23A of FIG. 5 from which the process main body to step S13-S23 shown in FIG. 4 has a reverse relationship.

It is determined whether or not there is recording authority information of the content as a premise of this processing, and is executed after it is determined that IP broadcast can be output.

  Here, “recording authority information” is information for determining whether or not there is an authority to record the selected content. Based on the presence or absence of this “recording authority information”, it is determined whether or not the selected content is a viewable area. It is assumed that recording of the selected content is permitted and stored in association with the selected content. Note that the recording authority information may be stored in association with the broadcast station information providing the content or the frequency information corresponding to the broadcast station 11 providing the content, not the content.

  This recording authority information is updated every predetermined period or every time the content is selected. Note that the user may not directly select the content, and the user may directly select the broadcast station 11 or a frequency corresponding to the broadcast station 11. In the following description, an example in which a user directly selects content is described. However, the user may directly select a broadcast station 11 or a frequency corresponding to the broadcast station 11.

  As shown in FIG. 6A, the portable recording / reproducing apparatus 12A connects to the Internet 14, transmits a content distribution request to the distribution server 13 corresponding to the selected content, and receives the IP broadcast. (Step S31). The portable recording / reproducing device 12A decodes and reproduces the received IP broadcast, and records the received IP broadcast in the storage unit 43 (step S32).

  And portable recording / reproducing apparatus 12A will stop the process which records the received IP broadcast in the memory | storage part 43, if reproduction | regeneration of the received IP broadcast is stopped by the instruction | indication from the operation part 33 (step S33). Then, the portable recording / reproducing apparatus 12A stops the connection to the Internet 14 (step S34), and ends the recording process (END).

  Further, as shown in FIG. 6B, the portable recording / reproducing apparatus 12A reproduces the IP broadcast content recorded in the storage unit 43 (step S35). Then, the portable recording / reproducing device 12A stops the reproduction process of the IP broadcast content recorded in the storage unit (step S36), and ends the reproduction process (END).

(Recording authority transfer process)
FIG. 7 is a flowchart for delegating the recording authority from the portable recording / reproducing apparatus 12A shown in FIG. 1 to the fixed recording / reproducing apparatus 12B, and showing the control relationship between the recording process and the reproducing process in both apparatuses. In the recording authority transfer process shown in FIG. 7, for example, the portable recording / reproducing device 12A is brought into the viewing-and-listening area of the broadcasting station 11, and the broadcast cannot be viewed in the region where the fixed recording / reproducing device 12B is installed. This is an effective process. When this recording authority delegation process is performed, the portable recording / reproducing apparatus 12A has no recording authority, so that the reception and viewing of the IP broadcast is maintained. On the other hand, in the fixed recording / reproducing apparatus 12B, since there is only a recording right, IP broadcast reception and recording are permitted but viewing is not permitted.

  First, the process from step S41 to step S50 executed by the portable recording / reproducing apparatus 12A will be described. When the content selection instruction information and the recording instruction information in the fixed recording / reproducing apparatus 12B are input from the operation unit 33, the portable recording / reproducing apparatus 12A connects to the Internet 14 and fixes the authentication processing described in FIG. This is performed with the mold recording / reproducing apparatus 12B (step S41). The portable recording / reproducing apparatus 12A determines whether or not the authentication process is acceptable (step S42).

  If the authentication process in step S42 passes, the portable recording / reproducing device 12A establishes an Internet connection with the fixed recording / reproducing device 12B (step S43). If it is determined that the authentication process in step S42 is unacceptable, the portable recording / reproducing device 12A does not establish an Internet connection with the fixed recording / reproducing device 12B (step S49).

  The portable recording / reproducing apparatus 12A delegates content recording authority to the fixed recording / reproducing apparatus 12B (step S44; hereinafter, a session is established with the fixed recording / reproducing apparatus 12B, and the state where the recording authority is delegated is referred to as “recording”. Called "Delegation Mode"). In the process of delegating the recording authority, for example, the fixed recording / reproducing apparatus 12B permits the fixed recording / reproducing apparatus 12B to receive and record the content from the server 13, and the content viewing and reproducing process is prohibited. The control information to be controlled is transmitted.

  The portable recording / reproducing apparatus 12A makes an IP broadcast distribution request to the distribution server 30, and receives the IP broadcast (step S45). The portable recording / reproducing device 12A decodes and reproduces the received IP broadcast, and instructs the fixed recording / reproducing device 12B to record the content distributed by the IP broadcast (step S46).

  Then, the portable recording / reproducing apparatus 12A records the IP broadcast when it stops the reproduction of the received IP broadcast, for example, when there is an instruction to stop the recording from the operation unit 33 or when the reserved recording time has expired. The fixed recording / reproducing apparatus 12B is instructed to cancel (step S47). The portable recording / reproducing device 12A receives the return of the IP broadcast recording authority from the fixed recording / reproducing device 12B (step S48). Then, the portable recording / reproducing apparatus 12A stops the Internet connection (step S50), and ends the recording authority transfer process (END).

  Next, processing from step S51 to step S60 executed by the fixed recording / reproducing apparatus 12B will be described. The fixed recording / reproducing apparatus 12B performs the authentication process described with reference to FIG. 4 with the portable recording / reproducing apparatus 12A (step S51). The fixed recording / reproducing apparatus 12B determines whether or not the authentication process is acceptable (step S52).

  If the fixed recording / reproducing apparatus 12B determines that the result is acceptable in step S52, the fixed recording / reproducing apparatus 12B establishes an Internet connection with the portable recording / reproducing apparatus 12A (step S53), and delegates the recording authority from the portable recording / reproducing apparatus 12A. (Step S54). On the other hand, if it is determined as unacceptable, the Internet connection with the portable recording / reproducing apparatus 12A is stopped (step S61), and the process is terminated (END).

  When the fixed recording / reproducing apparatus 12B has the recording authority transferred from the portable recording / reproducing apparatus 12A, the recording authority is transferred from the portable recording / reproducing apparatus 12A in step S54. A request is made and IP broadcast is received (step S55).

  The fixed recording / reproducing apparatus 12B prohibits real-time viewing of the content by the received IP broadcast and encrypts it with the public key Km (an example of the first key in the claims) of the authenticated portable recording / reproducing apparatus 12A ( Step S56). The public key used for encryption may be a public key different from the public key Km as long as it is a key provided by the authenticated portable recording / reproducing device 12A. Then, when receiving the recording instruction from the portable recording / reproducing device 12A in step S46, the fixed recording / reproducing device 12B records the encrypted content in the storage unit 43 (step S57).

  When the fixed recording / reproducing apparatus 12B receives a recording stop instruction from the portable recording / reproducing apparatus 12A in step S45, the fixed recording / reproducing apparatus 12B stops the process of recording the encrypted content in the storage unit 43 (step S58). The fixed recording / reproducing apparatus 12B stops receiving the IP broadcast (step S59). Then, the fixed recording / reproducing apparatus 12B returns the recording authority of the IP broadcast to the portable recording / reproducing apparatus 12A (step S60), and ends the process (END).

  As shown in FIG. 7, the portable recording / reproducing apparatus 12A that has entered the recording delegation mode can decode from the network I / F and listen to audio or display video in real time, for example. Since it is delegated to the fixed recording / reproducing apparatus 12B, it becomes impossible to record to the portable recording / reproducing apparatus 12A. On the other hand, since the paired fixed recording / reproducing apparatus 12B has obtained the recording authority, the content can be received from the network I / F, encrypted by the encryption unit, and recorded by the fixed recording / reproducing apparatus 12B. become. However, real-time viewing of received content is restricted by the main control unit 24.

  In the fixed recording / reproducing apparatus 12B, the authentication unit prevents the data from being decoded from the network I / F (that is, encrypts the data with the public key Km passed from the portable recording / reproducing apparatus 12A, and stores the encrypted data in the public key Km). It is recorded so that it cannot be decoded unless the corresponding secret key Kp is obtained, and the recorded data is restricted from being reproduced. Then, even if the storage unit 43 is removed from the apparatus and attached to another recording / reproducing apparatus, decoding becomes very difficult.

  In the fixed recording / reproducing apparatus 12B paired with the portable recording / reproducing apparatus 12A, the content transmitted from the distribution server 13 can be recorded. Also, if the recorded content is transmitted from the fixed recording / reproducing apparatus 12B to the portable recording / reproducing apparatus 12A, the transmitted data is encrypted, so it is safe because it cannot be decrypted even if it is extracted. It is. The data received by the portable recording / reproducing device 12A can be decrypted by the internal secret key and the decrypting unit, decoded, and returned to voice.

(Reproduction processing)
FIG. 8 is a flowchart showing a process of reproducing content in the portable recording / reproducing apparatus 12A after the process shown in FIG. 7 is performed. The process shown in FIG. 8 is a process that is executed by directly connecting to each other after the process shown in FIG. 7 is performed. For example, the process starts when the user carrying the portable recording / reproducing device 12A returns to his home and connects the portable recording / reproducing device 12A directly to the fixed recording / reproducing device 12B.

  The reproduction process shown in FIG. 8 is started when the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B are directly connected. Note that the processing may be started only when an instruction to start reproduction is given from the operation unit 33 of the portable recording / reproducing apparatus 12A or the fixed recording / reproducing apparatus 12B. The fixed recording / reproducing apparatus 12B is a portable recording / reproducing apparatus 12A for content encrypted with the public key Km (an example of the first key in the claims) of the portable recording / reproducing apparatus 12A recorded in the storage unit 43. (Step S71). Then, the portable recording / reproducing device 12A receives the content encrypted with the public key Km from the fixed recording / reproducing device 12B (step S72). Then, the portable recording / reproducing device 12A decrypts the content encrypted with the public key Km with its own secret key Kp (an example of the second key in the claims) (step S73). The portable recording / reproducing device 12A decodes and outputs the decrypted content, that is, the user views the IP broadcast (step S74). The portable recording / reproducing apparatus 12A stops the decoding of the decoded content when an instruction to stop the reproduction is given from the operation unit 33 or when the recorded IP broadcast program ends, that is, the user views the decoded content. Is stopped (step S75). Then, the fixed recording / reproducing apparatus 12B stops the transmission of the encrypted content (step S76). When the portable recording / reproducing device 12A is disconnected from the fixed recording / reproducing device 12B, the process ends (END).

  With the reproduction process shown in FIG. 8, the content recorded in the fixed recording / reproducing apparatus 12B outside the viewable area cannot be reproduced as it is without any particular limitation. The authority relationship of a certain content can be considered. Note that the reproduction process shown in FIG. 8 may be performed via the Internet 14. In that case, as shown in FIG. 9, after the authentication process shown in FIGS. 4 and 5 is executed, the processes after step S71 in FIG. 8 may be performed. In the example shown in FIG. 9, since the authentication process and encryption are performed even if transmitted via the Internet 14, the content can be reproduced only by the portable recording / reproducing apparatus 12A having the recording authority and has viewing restrictions. Can be considered.

  As described above, while the content distributed as IP broadcast from the distribution server 13 is received and recorded by the fixed recording / reproducing apparatus 12B, the portable recording / reproducing apparatus 12A is controlled so that the content cannot be recorded. Real-time viewing is possible. On the other hand, on the fixed recording / reproducing apparatus 12B side, a mechanism for controlling the real-time viewing of the content and the reproduction / viewing of the recorded content as it is cannot be realized.

  For example, the situation is such that the portable recording / reproducing device 12A in the viewable area records while viewing the content, and the fixed recording / reproducing device 12B outside the viewable region can simultaneously record the content. If it is allowed, content that originally has viewing restrictions creates a situation where it can be recorded regardless of the viewing area restrictions, which is not preferable.

  Further, if the content recorded in the fixed recording / reproducing apparatus 12B outside the viewable area allows a situation in which the content can be viewed in real time or the recorded content can be reproduced as it is, there is no restriction on viewing. This is not preferable because it creates a situation in which content with a content can be played back regardless of viewing area restrictions. Therefore, by realizing the above-described mechanism for these inconveniences, it is possible to consider the authority relationship of content with viewing restrictions.

  In addition, it can be assumed that content with viewing restrictions is recorded by the portable recording / reproducing device 12A, and the recorded content is directly transmitted to the fixed recording / reproducing device 12B via the Internet 14. In such a case, Unicast communication on the Internet 14 increases, and traffic on the Internet 14 is reduced compared to a method in which the distribution server 13 distributes content to the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B by multicast communication. It is also possible.

  In addition, by realizing the mechanism as described above, for example, when the storage capacity of the portable recording / reproducing device 12A owned by the user is insufficient to record the content transmitted from the distribution server 13, Although viewing is performed by the portable recording / reproducing device 12A, the recording of the content is changed to the fixed recording / reproducing device 12B at home, and then the user returns to the home and records it on the fixed recording / reproducing device 12B. It is also possible to reproduce the content that has been recorded.

  In the first embodiment, in consideration of the authority relationship of content with viewing restrictions in case the portable recording / reproducing device 12A is located in the content viewing area and the fixed recording / reproducing device 12B is located outside the viewing area. The portable recording / reproducing apparatus 12A confirms the position of the fixed recording / reproducing apparatus 12B immediately before the processing shown in FIG. 7, and the fixed recording / reproducing apparatus 12B is located outside the viewing area. In this case, it is possible to select the fixed recording / reproducing apparatus 12B to perform the same processing as in FIG. 6 when the fixed recording / reproducing apparatus 12B is located in the viewing area.

  A second embodiment of the present invention will be described. The second embodiment is different from the first embodiment in the pairing process and the authentication process shown in FIGS. Specifically, in the first embodiment, mutual authentication is performed between the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B. However, in the second embodiment, only one portable recording / reproducing device 12A is used. It is assumed that authentication is executed in the above, and a simpler method that does not authenticate each other is adopted. Even with this simple method, the effects described in the first embodiment can be achieved. In addition, since the structure is the same as the information provision system 1 shown in Example 1, while attaching | subjecting the same code | symbol about the same function and explaining it, illustration and description of each function are abbreviate | omitted.

(Pairing process)
The portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B are directly connected within a predetermined distance to perform pairing processing. The direct connection within a predetermined distance includes general-purpose connection means that cannot perform a long distance connection such as a wired connection such as a serial interface or USB, or a wireless connection such as BlueTooth (registered trademark), wireless LAN, or infrared communication. In addition, it is also effective to use an original bus or a unique communication line.

  FIG. 10 is a flowchart showing the pairing process in the information providing system according to the second embodiment of the present invention. As a premise of the following processing, the portable recording / reproducing apparatus 12A is assumed to have its own authentication information IDm, public key Km, and secret key Kp, and the fixed recording / reproducing apparatus 12B is connected to the own apparatus. It is assumed that the Internet connection information Lf is included. The internet connection information Lf here is, for example, an IP address or a MAC address set in the fixed recording / reproducing apparatus 12B.

  The pairing process shown in FIG. 10 starts when the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B are directly connected (START). The portable recording / reproducing device 12A transmits its authentication information IDm and public key Km to the fixed recording / reproducing device 12B (step S81).

  The fixed recording / reproducing apparatus 12B receives and stores the authentication information IDm and the public key Km transmitted from the portable recording / reproducing apparatus 12A in step S81 (step S82). Then, fixed mold recording / reproducing apparatus 12B transmits Internet connection information Lf for connecting to the self recording apparatus to portable recording / reproducing apparatus 12A (step S83).

  The portable recording / reproducing device 12A receives and stores the Internet connection information Lf transmitted from the fixed recording / reproducing device 12B in step S83 (step S84). When step S84 is completed, the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B are disconnected, and the pairing process ends (END).

  The pairing process shown in FIG. 10 causes the portable recording / reproducing apparatus 12A to pass the authentication information of its own apparatus and its own public key Km to the other party, thereby enabling the subsequent authentication process.

(Authentication process)
FIG. 11 is a flowchart illustrating the authentication process in the information providing system according to the second embodiment of the present invention. The portable recording / reproducing device 12A and the fixed recording / reproducing device 12B that have undergone the pairing process of FIG. 10 are then disconnected, and the portable recording / reproducing device 12A is brought into the viewable area of the broadcasting station 11. In such a situation, by establishing a session between the two devices via the Internet 14, they can communicate with each other and perform authentication processing there.

  In the authentication process shown in FIG. 11, the authentication information IDm of the portable recording / reproducing device 12A is requested from the fixed recording / reproducing device 12B side, and the information received from the portable recording / reproducing device 12A matches the authentication information of its own. Depending on whether or not the portable recording / reproducing apparatus 12A has undergone the pairing process, a process for confirming that the portable recording / reproducing apparatus 12A has been performed is performed. The authentication process shown in FIG. 11 is executed after the pairing process shown in FIG. 10 is performed, and the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B are connected to the Internet 14 and can communicate with each other. It is a precondition to start.

  The portable recording / reproducing device 12A connects to the fixed recording / reproducing device 12B based on the Internet connection information Lf for connecting to the fixed recording / reproducing device 12B (step 81). On the other hand, when the fixed recording / reproducing apparatus 12B receives a connection request from the portable recording / reproducing apparatus 12A in step S81, the fixed recording / reproducing apparatus 12B establishes communication with the portable recording / reproducing apparatus 12A and performs the pairing process shown in FIG. In order to confirm that it is the recording / reproducing apparatus 12A, the portable recording / reproducing apparatus 12A is requested to transmit the authentication information IDm (step S82).

  When the portable recording / reproducing device 12A receives the request for the authentication information IDm from the fixed recording / reproducing device 12B, the portable recording / reproducing device 12A transmits its own authentication information IDm to the fixed recording / reproducing device 12B (step S83). Note that the authentication information IDm may be encrypted before being transmitted.

  When receiving the authentication information from the portable recording / reproducing device 12A (step S84), the fixed recording / reproducing device 12B compares both with the authentication information IDm of the portable recording / reproducing device 12A stored by the pairing process shown in FIG. Are determined to match (step S85). As a result of the comparison, if the two match, the fixed recording / reproducing apparatus 12B is the portable recording / reproducing apparatus 12A that has undergone the pairing process shown in FIG. In this case, since it is not the portable recording / reproducing apparatus 12A that has undergone the pairing process shown in FIG. 10, the authentication is rejected (step S87). Then, the fixed recording / reproducing apparatus 12B transmits the pass / fail determination information to the portable recording / reproducing apparatus 12A (step S88).

  The portable recording / reproducing device 12A receives the pass / fail determination information transmitted from the fixed recording / reproducing device 12B (step S89), performs the pass / fail determination based on the pass / fail determination information (step S90), and passes. Is the fixed recording / reproducing apparatus 12B that has undergone the pairing process shown in FIG. 10, and therefore, it is determined to pass (step S91), and if it fails, the fixed recording / reproducing apparatus 12B that has undergone the pairing process shown in FIG. Therefore, it is determined as rejected (step S92).

  As in the authentication method shown in FIG. 11, an information providing system that achieves the same effect as that of the first embodiment can be realized by executing authentication processing based on one authentication information without authenticating each other. it can. In the second embodiment, the authentication process is performed using the authentication information IDm included in the portable recording / reproducing apparatus 12A. However, the authentication information included in the fixed recording / reproducing apparatus 12B is stored in the portable recording / reproducing apparatus during the pairing process shown in FIG. It may be transmitted to the playback device 12A side, and at the time of authentication processing, the authentication information may be transmitted to the fixed recording / playback device 12B to execute the determination.

  A third embodiment of the present invention will be described. In the third embodiment, the identification information of the portable recording / reproducing device 12A (for example, serial number information, MAC address information, etc. of the portable recording / reproducing device 12A) without the mutual authentication process shown in FIG. A process of transmitting content information including connection information (for example, connection information such as a URL of the distribution server 13) necessary for acquiring content desired to be recorded from the distribution server 13 to the fixed recording / reproducing apparatus 12B is performed. Then, when the content recording process is executed on the fixed recording / reproducing apparatus 12B side, depending on whether the location where the fixed recording / reproducing apparatus 12B is located is a viewable area of the content received from the distribution server 13 or not. Then, by setting a flag for controlling whether or not the content can be reproduced and recording the flag and the content received from the distribution server 13 in association with each other, the reproduction control of the content on the fixed recording / reproducing apparatus 12B side is performed. Is. Even with this method, the effects described in the first embodiment can be obtained. In addition, since the information provision system of Example 3 is the same structure as the information provision system 1 shown in Example 1, it attaches | subjects and demonstrates the same code | symbol about the same function. Description is omitted.

  FIG. 12 is a flowchart showing a recording process in the information providing system according to the third embodiment of the present invention. In the following processing, the portable recording / reproducing device 12A has its own device identification information, the Internet connection information Lf of the fixed recording / reproducing device 12B, the URL of the broadcasting station 11 and the distribution server 13 corresponding to the broadcasting station 11. Description will be made on the assumption that the connection information such as is held in advance. The internet connection information Lf here is, for example, an IP address or a MAC address set in the fixed recording / reproducing apparatus 12B.

  The portable recording / reproducing apparatus 12A selects content based on the input of content selection instruction information from the operation unit 33 (step S110). The portable recording / reproducing apparatus 12A determines whether or not it is a viewable area of the content selected in step S110 (step S111). If it is a viewable area (YES in step S111), the Internet 14 is checked. The content is received from the distribution server 13 via the output. That is, the user is allowed to view the content (step S112).

  In step S111, the portable recording / reproducing apparatus 12A executes a method for determining whether or not the selected content is within the viewable area, for example, corresponding to the distribution server 13 that distributes the selected content. The broadcast station 11 to be identified is identified, and the received signal level of the broadcast wave from the identified broadcast station 11 is acquired by the tuner unit 23, and when it is equal to or higher than the predetermined received signal level, it is determined that it is within the viewable area. When the received signal level is lower than the predetermined reception signal level, it is determined that it is not within the viewable area. Alternatively, a database in which the latitude / longitude information where the broadcasting station 11 is located and the latitude / longitude information that is the viewable area of the broadcasting station 11 is stored in the portable recording / reproducing device 12A. By referring to the latitude / longitude information detected by the detection unit 29, the information of the specified broadcast station 11, and the information of this database, it may be determined whether or not the video is within the viewable area. . In the above description, in steps S110 and S111, the content is selected based on the input of the content selection instruction information from the operation unit 33, and it is determined whether the selected content is a viewable area. The broadcast station 11 may be selected based on the broadcast station selection instruction information or the frequency selection instruction information, and it may be determined whether or not the selected broadcast station 11 is a viewable area. That is, the content can be specified also from the broadcast station selection instruction information and the frequency selection instruction information, and the method for specifying the content is not limited to these.

  Thereafter, the portable recording / reproducing apparatus 12A determines whether or not the recording instruction information in the fixed recording / reproducing apparatus 12B is input from the operation unit 33 (step S113), and the recording instruction information is input from the operation unit 33. In step S114, Internet connection processing with the fixed recording / reproducing apparatus 12B is executed based on the Internet connection information Lf of the fixed recording / reproducing apparatus 12B. Note that the portable recording / reproducing apparatus 12A repeats the determination process of step S113 when the recording instruction information is not input to the fixed mold recording / reproducing apparatus 12B from the operation unit 33 (NO in step S113). In addition to determining whether or not the recording instruction information is input from the operation unit 33, it may be determined that the recording instruction information is automatically input when the remaining battery level or the storage capacity is low. .

  Then, the portable recording / reproducing device 12A performs fixed-type recording / reproduction of recording instruction information for instructing recording of content, content information currently being viewed, recording authority information for permitting recording of the content, and identification information of the device itself. It transmits to the apparatus 12B via the Internet 14 (step S115). Thereafter, the portable recording / reproducing device 12A transmits the recording authority information for permitting the recording of the content to the fixed recording / reproducing device 12B, and therefore prohibits the recording process of the currently viewed content on the own device.

  Here, as a specific process for prohibiting the recording process in the own device, for example, when content recording instruction information is input from the operation unit 33, the presence / absence of the recording authority information of the content is determined. In such a case, the recording is not permitted, and as a result, the portable recording / reproducing apparatus 12A prohibits the recording process of the content. The recording authority for each content may be set, but the recording authority for each broadcasting station 11 and the recording authority for each frequency corresponding to the broadcasting station 11 may be controlled not to permit recording. Further, the information transmitted from the portable recording / reproducing apparatus 12A to the fixed recording / reproducing apparatus 12B may be information of the broadcasting station 11 instead of the content information.

  Then, the portable recording / reproducing apparatus 12A determines whether or not the recording stop instruction information in the fixed recording / reproducing apparatus 12B is input from the operation unit 33 (step S117), and the recording stop instruction information is input from the operation unit 33. If there is (YES in step S117), the recording stop instruction information is transmitted to the fixed recording / reproducing apparatus 12B (step S118). Then, the portable recording / reproducing apparatus 12A determines whether or not the viewing end instruction information of the currently viewed content is input from the operation unit 33 (step S119), and the viewing end instruction information is input from the operation unit 33. If YES in step S119, the Internet connection is stopped (step S120), and the process ends (END). Note that the portable recording / reproducing apparatus 12A, if there is no input of the viewing end instruction information of the currently viewed content from the operation unit 33 (NO in step S119), the step is repeated until the viewing end instruction information is input. The determination process of S119 is repeated.

  On the other hand, the fixed recording / reproducing apparatus 12B receives the recording instruction information, the content information, the recording authority information relating to the currently viewed content transmitted from the portable recording / reproducing apparatus 12A in step S115, and the portable recording / reproducing apparatus 12A. Is received (step S121), it is determined whether or not the own apparatus is within the viewable area of the content viewed on the portable recording / reproducing apparatus 12A (step S122).

  Note that, in step S122, as a method for determining whether or not the content is viewed within the viewable area of the content that has been viewed by the portable recording / reproducing device 12A, executed by the fixed recording / reproducing device 12B, for example, the received content information When the broadcast station 11 corresponding to the distribution server 13 that provides the content is identified, the received signal level of the broadcast wave from the identified broadcast station 11 is acquired by the tuner unit 23, and is equal to or higher than the predetermined received signal level. Is determined to be within the viewable area, and when it is less than the predetermined reception signal level, it is determined not to be within the viewable area. Alternatively, a database in which the latitude / longitude information where the broadcast station 11 is located and the latitude / longitude information that is the viewable area of the broadcast station 11 is stored in the apparatus, and the fixed recording / reproducing apparatus 12B By referring to the latitude / longitude information detected by the position information detection unit 29, the information of the specified broadcasting station 11, and the information of this database, it is determined whether or not the area is within the viewable area. Also good.

  If fixed-type recording / reproducing apparatus 12B determines that the area is not a viewable area in step S122 (NO in step S122), a flag prohibiting reproduction of content (hereinafter, this flag is referred to as “content reproduction disabled flag”). Yes, the content playback is prohibited when it is on, and the playback is permitted when it is off). This flag, the identification information of the portable recording / reproducing device 12A, and the distribution server 13 All the received contents are associated and recorded in the storage unit 43 (step S123).

  On the other hand, if the fixed recording / reproducing apparatus 12B determines that the area is a viewable area in step S122 (YES in step S122), the fixed recording / reproducing apparatus 12B turns off the content non-reproducible flag and receives this flag and the distribution server 13 The contents are associated and recorded in the storage unit 43 (step S124). Then, when the fixed recording / reproducing apparatus 12B receives the recording stop information transmitted by the portable recording / reproducing apparatus 12A in step S118 (step S125), the fixed recording / reproducing apparatus 12B stops the recording process of the received content and ends the process (step S125). Step S126).

  Note that, in the processing from step S117 to step S120 shown in FIG. 12, the presence / absence determination from the operation unit 33 is separately performed for the recording stop instruction information and the viewing end instruction information. If the recording stop instruction information is not input, the recording stop instruction information is transmitted to the fixed recording / reproducing apparatus 12B as if the recording stop instruction information has been input. The connection may be stopped and content viewing may be terminated.

  FIG. 13 is a flowchart showing processing executed between the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B after the processing of FIG. The process shown in FIG. 13 is started when the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B shown in FIG. 1 are directly connected.

  The portable recording / reproducing apparatus 12A transmits its own identification information to the fixed recording / reproducing apparatus 12B (step S131), and ends the process (END).

  On the other hand, the fixed recording / reproducing apparatus 12B receives the identification information transmitted from the portable recording / reproducing apparatus 12A in step S131 (step S132). Then, the fixed recording / reproducing apparatus 12B searches the storage unit 43 of the own apparatus for the presence / absence of the content recorded in association with the identification information that is the same as the identification information received in step S132. (Step S133), and if it is determined that there is content (YES in step S133), the content reproduction disable flag of the content is set to off (that is, reproduction is possible) (step S134), and the process is performed. End (END). If it is determined that there is no recorded content (NO in step S133), the fixed recording / reproducing device 12B ends the process (END).

  As shown in FIG. 13, the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B are directly connected, and when the identification information of the portable recording / reproducing apparatus 12A matches, reproduction on the fixed recording / reproducing apparatus 12B side is performed. Can be considered in consideration of the authority relationship of content with viewing restrictions.

  In the third embodiment, the content reproduction disabled flag is turned on when the content is not viewable in step S122 of the fixed recording / reproducing apparatus 12B. However, for example, the position information of the portable recording / reproducing apparatus 12A is acquired, When compared with the position information of the fixed recording / reproducing apparatus 12B, when the user is in the same area or when the distance is equal to or larger than a predetermined threshold, the content reproduction impossibility flag may be turned on. For example, when the fixed recording / reproducing device 12B and the portable recording / reproducing device 12A are not in the same area, or when the distance is long, the content designated by the portable recording / reproducing device 12A is stored in the fixed recording / reproducing device 12B. This is because viewing is often impossible. For example, in the case of Japan, areas such as Kanto and Kansai and prefectures can be set as areas, and thresholds that can cover areas and prefectures such as Kanto and Kansai can be set as predetermined thresholds.

  Embodiment 4 of the present invention will be described. In the fourth embodiment, content information including connection information necessary for the user to acquire content desired to be recorded from the distribution server 13 without performing the mutual authentication processing shown in FIG. The connection information such as URL, information that can uniquely identify the content, and the public key and private key set by the portable recording / reproducing device 12A for each content are stored in association with each other, and then the fixed recording / reproducing device 12B. The content information and the content-specific public key are transmitted. Then, when the content recording process is executed on the fixed recording / reproducing apparatus 12B side, the content is encrypted with the public key depending on whether the content received from the distribution server 13 is viewable or not. By performing the recording, the reproduction of the content on the fixed recording / reproducing apparatus 12B side cannot be reproduced without the secret key held by the portable recording / reproducing apparatus 12A. Even with this method, the effects described in the first embodiment can be obtained.

  The information providing system according to the fourth embodiment has the same configuration as the information providing system 1 shown in the first embodiment. Therefore, the same functions are denoted by the same reference numerals, and are illustrated and described. Description is omitted.

  FIG. 14 is a flowchart showing a recording process in the information providing system according to the fourth embodiment of the present invention. 14, the processes given the same step numbers as those shown in FIG. 12 (steps S110 to S113, step S114, step S116, step S117, step S118 to step S120, step S122, step Since S125 and step S126) are the same, the description will be simplified or omitted.

  When the portable recording / reproducing device 12A performs the processing of step S110 to step S112, and in the determination of step S113, if the recording instruction information is input from the operation unit 33 in the fixed recording / reproducing device 12B, its contents A public key and a private key unique to each are generated and set, and connection information necessary for acquiring the content from the distribution server 13 is associated with each other and stored in the RAM 42 of the own apparatus (step S113A). When the Internet connection with the fixed recording / reproducing apparatus 12B is established in step S114, the portable recording / reproducing apparatus 12A has recording instruction information for instructing recording of content, content information, and recording authority information for permitting recording of the content. In addition, the public key set uniquely for the content is transmitted to the fixed recording / reproducing apparatus 12B via the Internet 14 (step S115A). Thereafter, the portable recording / reproducing apparatus 12A executes the processes of Step S116 to Step S120.

  On the other hand, the fixed recording / reproducing apparatus 12B transmits recording instruction information for instructing recording of content, content information, recording authority information for permitting recording of the content, transmitted from the portable recording / reproducing apparatus 12A in step S115A, and A public key set uniquely for the content is received (step S121A). Thereafter, it is determined whether or not the device is within the viewable area of the content that was being viewed on the portable recording / reproducing device 12A (step S122), and if it is determined that the content is not within the viewable area (step S122). NO), the content is encrypted with the public key unique to the content and recorded in the storage unit 43 (step S123A).

  On the other hand, if the fixed recording / reproducing apparatus 12B determines in step S122 that it is within the viewable area (YES in step S122), it records the content as it is in the storage unit 43 as usual (step S124A). Then, the fixed recording / reproducing apparatus 12B executes the processing from step S125 to step S126 and ends (END).

  In the processing from step S117 to step S120 shown in FIG. 14 as well as the processing in FIG. 12, if the viewing end instruction information is input from the operation unit 33, the recording stop instruction information is not input. Even in this case, the recording stop instruction information may be transmitted to the fixed recording / reproducing apparatus 12B on the assumption that the recording stop instruction information has been input, and the content connection may be terminated by stopping the Internet connection.

  FIG. 15 is a flowchart showing a process executed between the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B after the process of FIG. The process shown in FIG. 15 is started when the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B shown in FIG. 1 are directly connected within a predetermined distance. The predetermined distance is preferably set to about several tens of meters at the maximum, which can be determined as the same building. This process may be started when the distance between the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B is equal to or less than a predetermined threshold, instead of the direct connection within the predetermined distance. Whether or not the distance between the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B is equal to or smaller than a predetermined threshold value is determined based on the positional information of the portable recording / reproducing device 12A and the positional information of the fixed recording / reproducing device 12B. It may be used, or may be determined based on whether or not near field communication such as BlueTooth (registered trademark), wireless LAN, and infrared communication is connectable. As the predetermined threshold value, it is preferable to set a value of about several tens of meters at the maximum, which can be determined as the same building. Further, communication between the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B may use an Internet connection.

  The portable recording / reproducing device 12A transmits the content information stored in the RAM 42 to the fixed recording / reproducing device 12B and the secret key set specifically for the content (step S141), and ends the processing (END). .

  On the other hand, the fixed recording / reproducing apparatus 12B receives the content information and the secret key transmitted from the portable recording / reproducing apparatus 12A in step S141 (step S142). Then, the fixed recording / reproducing apparatus 12B determines the presence / absence of content corresponding to the content information received in step S142 by searching the storage unit 43 of the own apparatus (step S143). (YES in step S143), the content encrypted with the public key is decrypted with the private key (step S144), and the process ends (END). If it is determined that there is no recorded content (NO in step S143), the fixed recording / reproducing device 12B ends the process (END).

  As shown in FIG. 15, the portable recording / reproducing device 12A and the fixed type recording / reproducing device 12B are directly connected to determine whether or not the content corresponding to the content information matches. By decrypting, it becomes possible to reproduce the content on the fixed recording / reproducing apparatus 12B side after that, so that it is possible to consider the authority relationship of the content with viewing restrictions.

  The process shown in FIG. 15 has been described with respect to the case where the portable recording / reproducing apparatus 12A and the fixed recording / reproducing apparatus 12B are directly connected, but the recording is performed on the fixed recording / reproducing apparatus 12B side via the Internet 14. The content may be reproduced on the portable recording / reproducing apparatus 12A side.

  FIG. 16 is a flowchart illustrating an example of a reproduction process in the information providing system according to the fourth embodiment of the present invention. In the process shown in FIG. 16, the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B are in the state where the Internet connection is established, and the process shown in FIG. It is assumed that converted content has been recorded.

  The portable recording / reproducing device 12A selects the content to be viewed from the content information requested to be recorded to the fixed recording / reproducing device 12B (step S151). For example, the portable recording / reproducing apparatus 12A displays a list of content titles requested to be recorded on the display device 35 of the fixed recording / reproducing apparatus 12B, and the user operates the operation unit 33 to select a content selection instruction. To input.

  The portable recording / reproducing apparatus 12A transmits content information (such as information for uniquely identifying the content) and content transmission instruction information related to the content selected in step S151 to the fixed recording / reproducing apparatus 12B (step S151). S152). Then, the portable recording / reproducing device 12A determines whether or not the content is received from the fixed recording / reproducing device 12B (step S153). When the content is received (YES in step S153), the portable recording / reproducing device 12A corresponds to the received content. The content is decrypted and reproduced with the secret key, and the process is terminated (END). The portable recording / reproducing apparatus 12A determines whether or not the content has been received until a predetermined time (for example, 30 seconds) elapses (NO in step S155), and the state in which no content is received in step S153 is the predetermined time. If it has elapsed (YES in step S155), it is displayed on the display device 35 that no content has been found, and the process is terminated (END).

  On the other hand, when the fixed recording / reproducing apparatus 12B receives the content information and the content transmission instruction information transmitted from the portable recording / reproducing apparatus 12A by the process of step S152 (step S157), the fixed recording / reproducing apparatus 12B refers to its own storage unit 43. The presence / absence of content corresponding to the content information is determined (step S158).

  When there is content corresponding to the content information with reference to its own storage unit 43 (YES in step S158), fixed recording / reproducing device 12B transmits the corresponding content to portable recording / reproducing device 12A. (Step S159), and the process is terminated. If there is no content corresponding to the content information with reference to its own storage unit 43 (NO in step S158), the fixed recording / reproducing device 12B ends the process (END). If there is no content corresponding to the content information with reference to its own storage unit 43 in the determination in step S158, the processing is terminated as it is, but a message that there is no content is transmitted to the portable recording / reproducing apparatus 12A. May be.

  As shown in FIG. 16, the content encrypted on the fixed recording / reproducing device 12B side is decrypted and reproduced on the portable recording / reproducing device 12A side, for example, storage in the portable recording / reproducing device 12A owned by the user. Even in a situation where the capacity is insufficient to record the content transmitted from the distribution server 13, the content is recorded by the fixed recording / reproducing device 12B at home, and then portable. It is possible to reproduce on the recording / reproducing apparatus 12A side. This is because even if it is via the Internet 14, it is encrypted so that the authority relationship of content with viewing restrictions is properly considered, and even if the content is wiretapped on the Internet 14, it cannot be decrypted (cannot be viewed) Is realized. In the description of the fourth embodiment, the encryption is performed by the public key cryptosystem using the public key and the secret key at the time of encryption and decryption, but the common key cryptosystem is changed according to the required security. It may be used.

  As mentioned above, although concretely demonstrated based on Examples 1-4 and those modifications which concern on this invention, this invention is not limited to these Examples and its modification, and deviates from the summary of invention. Various modifications and changes can be made without departing from the scope. For example, the relationship between the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B is described in a situation where the region where the portable recording / reproducing device 12A exists and the region where the fixed recording / reproducing device 12B is installed are different. However, both of them may be within the viewable area of the same broadcasting station 11. When both are within the viewable area of the same broadcasting station 11, normal playback processing and recording processing may be performed without limiting the content playback processing and recording processing by the above-described mechanism.

  Further, in the first to fourth embodiments and the modifications thereof according to the present invention, the description has been made on the assumption that the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B are related. The above-described processing may be executed between the portable recording / reproducing apparatuses 12A located at the same position.

  Also, in the first to fourth embodiments and their modifications according to the present invention, IP broadcast content (such as a program composed of one or more of video, audio, and still images) is used as content with limited viewing. As described above, the content is not limited to IP broadcasting such as music distribution, games, and news as long as the content has other area restrictions on viewing.

  Further, in the first to fourth embodiments and their modifications according to the present invention, the IP broadcast distributed from the distribution server 13 is the broadcast wave of the broadcasting station 11 in the portable recording / reproducing device 12A and the fixed recording / reproducing device 12B. Although the description has been made on the premise of determining whether or not output is possible based on the determination of the signal level, the distribution server 13 can also perform broadcasting in these devices from the portable recording / reproducing device 12A or the fixed recording / reproducing device 12B. The broadcast wave signal level of the station 11 may be transmitted, and the distribution server 13 may determine whether or not the IP broadcast can be distributed. In that case, control information as controlled in the authority delegation mode is transmitted from the portable recording / reproducing apparatus 12A side to the distribution server 13 so that the contents can be distributed to the fixed recording / reproducing apparatus 12B. 13 and when the distribution server 13 distributes the IP broadcast to the fixed recording / reproducing apparatus 12B, the control information is also added to the fixed recording / reproducing apparatus 12B, and the fixed recording / reproducing is performed based on the control information. Recording processing, decoding processing, and the like in the device 12B may be performed. Since such a method is a unicast method, it is difficult to reduce the traffic on the Internet 14, but the authority relationship can be considered.

  Also, the distribution server 13 transmits the signal level of the broadcast wave of the broadcasting station 11 in the portable recording / reproducing apparatus 12A or the fixed recording / reproducing apparatus 12B, and the distribution server 13 side determines whether or not IP broadcasting can be distributed. When the fixed recording / reproducing apparatus 12B side does not need to have a viewing restriction function based on its own position, the signal level of the broadcast wave of the broadcasting station 11 of the portable recording / reproducing apparatus 12A is not necessary. Information or its own location information (for example, IP address or zip code) is transmitted to the fixed recording / reproducing apparatus 12B. The fixed recording / reproducing apparatus 12B transmits the broadcast wave of the broadcasting station 11 of the portable recording / reproducing apparatus 12A. Based on the signal level information or the position information of the fixed recording / reproducing device 12B, a transmission request for IP broadcast is sent to the distribution server 13 to record the content. It may be. As described above, even when at least one device has a function of measuring the signal level of the broadcast wave of the broadcasting station 11 at its own position or its own position information and the device can receive IP broadcasts, the present invention It is possible to achieve the same effect as each of the embodiments.

  In addition, the pairing processing of the first and second embodiments and the modification thereof according to the present invention have been described with one portable recording / reproducing device 12A and one fixed recording / reproducing device 12B (one-to-one correspondence). If the portable recording / reproducing device 12A has abundant reception capability and recording capability, a single portable recording / reproducing device 12A is paired with a plurality of fixed recording / reproducing devices 12B (one-to-many correspondence). Is also possible. It is also possible to pair one fixed recording / reproducing apparatus 12B with a plurality of portable recording / reproducing apparatuses 12A. Even when a single fixed recording / reproducing device 12B is paired with a plurality of portable recording / reproducing devices 12A, the portable recording / reproducing device 12A only decodes what is encrypted with its own public key Km. Since it is not possible to do so, it is possible to consider the authority relationship.

  Further, in the information providing system 1 described in the first to fourth embodiments and the modifications thereof according to the present invention, the portable recording / reproducing apparatus 12A is the first information processing apparatus, and the fixed recording / reproducing apparatus 12B is Although described as the second information processing apparatus, in addition, when both the first information processing apparatus and the second information processing apparatus are the portable recording / reproducing apparatus 12A or the fixed recording / reproducing apparatus 12B, The case where the fixed recording / reproducing apparatus 12B is the first information processing apparatus and the portable recording / reproducing apparatus 12A is the second information processing apparatus is not excluded.

  Further, all or part of the processing executed by the portable recording / reproducing apparatus 12A or the fixed recording / reproducing apparatus 12B of the information providing system 1 described in the first to fourth embodiments and the modifications thereof according to the present invention is performed by a program. It may be configured to function as each means by installing this program in an information processing apparatus (computer).
