[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an information storage device that receives and stores information such as TV broadcasts.
[0002]
[Prior art]
In recent years, digital TV broadcasting and data broadcasting linked to TV broadcasting or independent from TV broadcasting have begun to be performed, and new receiving apparatuses are being developed in correspondence with these new broadcasting formats. This receiving apparatus is configured by using two tuners and a hard disk, and can record broadcast contents and the like on the hard disk. At present, as a method of using this receiving apparatus, the hard disk is divided into two areas called a user area and a provider area so that broadcasts received by the user using one tuner can be recorded in the user area. In the provider area, the other channel is fixed and the content of the data broadcast received by the tuner that cannot be changed by the user is forcibly saved, and the provider area is lent to the data broadcast provider. Is considered.
[0003]
[Problems to be solved by the invention]
However, there is a risk of failure in hard disks. As a result, the content recorded by the user cannot be read. In addition, when conducting the above business, it is necessary to take measures when a problem such as a failure occurs.
[0004]
Such a problem is not limited to a hard disk, but may be surely generated as long as it is a single other recording medium. However, simply duplicating the recording may make the receiving apparatus expensive and complicated.
[0005]
Therefore, the present invention solves the above-mentioned problems, and easily and easily restores or rewrites information that has become unreadable when a hard disk or the like fails, or information that has failed to be written due to a failure or insufficient capacity of the hard disk or the like. In order to provide a means to do this, an information identifier for identifying information received by the receiving unit is generated or received, and the original information can be restored based on the information identifier.
[0006]
[Means for Solving the Problems]
That is, the information storage device according to the present invention stores the information received by the reception unit in the information storage unit and generates an information identifier for identifying the information from the information by the information identifier generation unit, as shown in FIG. The information identifier is stored in an information identifier storage unit that is separate from the information storage unit. Here, the separation includes physical separation or logical separation by dividing an area. Instead of generating the information identifier by the information identifier generating unit, the information and the information identifier may be received by the receiving unit as shown in FIG.
[0007]
In this case, even if a problem occurs in the information storage unit, the information can be restored or rewritten using the information identifier as a clue if the original information exists as in TV broadcasting. In addition, since only the information identifier needs to be stored in this way, it is possible to avoid a heavy burden on the equipment.
[0008]
In order to restore information that has become unreadable due to a medium failure or the like, it is desirable that the information identifier storage unit store only the information identifier that identifies the stored information among the received information. In this way, it is possible to determine which information was stored from the list of stored information identifiers, and it is sufficient to read the information in this list at the time of restoration.
[0009]
In addition, in order to rewrite information that has failed to be written due to a medium failure or insufficient capacity, the information identifier storage unit identifies information that is not stored among the received information, contrary to the previous stage. It is desirable to store only information identifiers. In this way, it is possible to determine which information has failed to be written from the list of stored information identifiers, and it is only necessary to read the information in this list when rewriting.
[0010]
On the other hand, a storage identifier generation unit for generating a storage identifier for identifying whether or not the information is stored is further provided, and the generated storage identifier is stored together with the information identifier. Since it is possible to distinguish from information that is not stored, it is easy to selectively or simultaneously rewrite information that has been stored and cannot be read, and rewrite information that has not been stored due to failed writing. Can be provided.
[0011]
By further comprising a second receiving unit that receives information identified based on the stored information identifier, and a second information storage unit that stores the information received by the second receiving unit, Information can be restored or rewritten online.
[0012]
If the restoration or rewriting of the information is performed according to the stored storage identifier, restoration or rewriting of stored data or data that has failed to be stored can be selectively performed.
[0013]
If a transmission unit that transmits the information identifier or the information identifier and the storage identifier is further provided, information for restoration or rewriting can be requested online. At this time, it is necessary to specify the billing source. To this end, it is necessary to further include a management unit for managing a receiver identifier for identifying a receiver who receives the information, and to have the receiver identifier function.
[0014]
On the other hand, as shown in FIG. 3, the receiving unit receives information, stores the information in the information storage unit, generates an information identifier for identifying the information in the information identifier generation unit, and then manages the information in the management unit. A receiver identifier for identifying a receiver to be received may be managed, and the information identifier and the receiver identifier may be transmitted from a transmitter. As for the information identifier, the information identifier may be received by the receiving unit instead of providing the information identifier generating unit as shown in FIG.
[0015]
In this case, it is possible to notify on-line each time information is received.
[0016]
Furthermore, by transmitting only the information identifier for identifying the stored information among the received information, the transmitting unit can be notified of which information has been reliably received, and conversely, it is not stored. If only an information identifier for identifying information is transmitted, error information indicating a storage failure can be notified.
[0017]
In addition, a storage identifier generation unit for generating a storage identifier for identifying whether or not the information has been stored is further included, and if the generated storage identifier is transmitted together with the information identifier, the storage succeeds or fails. It will be possible to convey both information.
[0018]
In order to respond to the information request from the receiver side on the information issuing side, a server device is prepared and an information storage system is assembled in combination with the information storage device. The information identifier transmitted from the information storage device may be received, the information identified by the information identifier may be acquired by the information acquisition unit, and the acquired information may be stored in the information storage unit. In this way, by sending the stored data separately to the receiver side, it is possible to respond to a request for information from the receiver side.
[0019]
Furthermore, an information identifier storage unit is provided in the server device instead of the information storage device on the receiver side, the information identifier is stored in the information identifier storage unit in association with the receiver identifier, and the server device An information storage unit may be provided that receives a receiver identifier and stores information identified based on the information identifier stored in association with the receiver identifier. Even in this case, since the information identifier is stored in association with the receiver identifier, the information request can be made for each recipient.
[0020]
Moreover, you may prepare what provided the transmission part in the server apparatus of the front two steps | paragraphs. In this case, information requested by the receiver can be transmitted online.
[0021]
In addition, if the receiving unit also receives a storage identifier and stores or transmits information identified based on the information identifier according to the storage identifier, it is possible to distinguish between stored information and unstored information, It is possible to easily or selectively rewrite information that has been stored once and cannot be read, and information that has not been stored due to failure to be written can be rewritten.
[0022]

[0029]
Hereinafter, each functional block of the information storage device 1 will be described in detail.
[0030]
The receiving unit 11 is for receiving the information I transmitted from the broadcasting station BS via the satellite SL, and is configured using the tuners 104a and 104b. Here, the information I refers to content such as BS / CS digital TV broadcast or data broadcast.
[0031]
The information storage unit 12 receives the information I received from the reception unit 11 and stores it, and is formed in a predetermined area of the hard disk 106. In the present embodiment, the information storage unit 12 is divided into a provider area and a user area. Here, broadcasts received by the user using the tuner 104a are recorded in the user area. On the other hand, the content of the data broadcast of the fixed channel is forcibly saved by using another tuner 104b in the provider area.
[0032]
The information identifier generation unit 13 is for generating an information identifier S1 for identifying the information I. This information identifier S1 is generated from the received date, time, channel, etc., and is associated with each information I as unique. An example of the information identifier S1 is shown in FIG.
[0033]
Instead of providing the information identifier generating unit 13 in the information storage device 1, the receiving unit 11 may receive information I and the information identifier S1 for identifying the information I in advance as a set. Examples of the functional block diagram and the information identifier S1 in this case are shown in FIGS. 10 and 11, respectively.
[0034]
The information identifier storage unit 14 is for receiving and storing the information identifier S1 generated by the information identifier generation unit 13 or received by the reception unit 11, and is formed in a predetermined area of the memory card 108.

As for the separation method, a method of logically dividing the hard disk 106 by setting a plurality of partitions and applying a part of the partition may be used.
[0036]
Further, since the information identifier storage unit 14 stores the information identifier S1 for identifying the information I to be restored or rewritten, it is preferable to use a storage medium that does not easily fail than the information storage unit 12.
[0037]
The storage identifier generation unit 15 is for generating a storage identifier S2 having a function of identifying whether each piece of information I identified by the information identifier S1 is normally stored or not stored. The storage identifier S2 is associated with the information identifier S1, and takes a binary value of 1 and 0, for example. In the present embodiment, a case of 1 indicates a normally stored state, and a case of 0 indicates a state that is not normally stored.
[0038]
The management unit 16 manages a receiver identifier S3 for providing information for identifying a receiver on the server device 2 side that accepts transmission, that is, each receiver, that is, this embodiment in the internal memory 102 or the like. Then, the receiver identifier S3 unique to each information storage device 1 or user is stored.
[0039]
The process reception unit 18 is configured to receive and generate a process identifier S4 for selecting a process to be performed by the server apparatus 2 by using a process input apparatus 111. This processing identifier S4 is for identifying the result of selection of whether to restore the stored information and rewrite the information that failed to be stored. In this embodiment, 11, 10, 01, Takes 4 values of 00. When the first digit of the process identifier S4 is 1, the stored information is restored, and when it is 0, this is not performed. Further, when the last digit of the process identifier S4 is 1, rewriting of the information that failed to be stored is performed, and when it is 0, this is not performed.
[0040]
The transmission unit 17 receives the information identifier S1 and the storage identifier S2 stored from the information identifier storage unit 14, the receiver identifier S3 from the management unit 16, and the processing identifier S4 from the processing reception unit 18, respectively. The information is transmitted to the apparatus 2 and is configured using the communication interface 109. An outline of the transmission contents is shown in FIG.
[0041]
As will be described later, the second receiving unit 11b is for receiving the information I transmitted from the server device 2 when restoring or rewriting the information that has become unreadable or the information I that has failed to be stored. is there. The second information storage unit 12b is for storing the information I received by the second reception unit 11b. In the present embodiment, the second receiving unit 11b and the second information storage unit 12b are different from the receiving unit 11 and the information storage unit 12, respectively, but may be the same.
[0042]
Next, each functional block of the server device 2 will be described in detail.
[0043]
The receiving unit 21 receives, that is, receives, the information identifier S1, the storage identifier S2, and the receiver identifier S3 transmitted from the information storage device 1, and is configured using the communication interface 206. is there.
[0044]
The information acquisition unit 22 is for acquiring the information I identified by the received information identifier S1 from, for example, the broadcasting station BS via the network. Although not shown, the broadcasting station BS and the server apparatus 2 are connected via the network N.
[0045]
The information storage unit 24 stores the information I acquired by the information acquisition unit 22 and is configured using the external storage device 203.
[0046]
If the information storage unit 24 is the same type of storage medium as the information storage unit 12, these can be easily replaced.
[0047]
The transmitting unit 25 is a receiver identified based on the receiver identifier S3 received by the receiving unit 21 with the information I acquired by the information acquiring unit 22, specifically, the second receiving unit 11b of the information storage device 1. To send to.
[0048]
The receiver is not necessarily the same as the information storage device 1, and may be another information storage device. In this case, the receiver identifier S3 identifies the user.
[0049]
On the information storage device 1 side, the information I is received by the second receiving unit 11b so that it can be identified based on the information identifier S1 stored in the information identifier storage unit 14 of the information storage device 1, If stored in the second information storage unit 12b, the information I can be restored or rewritten online.
[0050]
Hereinafter, the operation of the information system S will be described. Further, flowcharts are shown in FIGS.
[0051]
First, as shown in FIG. 14, the information storage apparatus 1 side receives the information I by the tuners 104a and 104b (reception unit 11) (reception step ST1). Next, the information I received by the tuner 104b with the fixed channel is forcibly stored in the provider area of the information storage unit 12, or the information I received by the other tuner 104a is stored in the information storage unit 12 as necessary. Store in the user area (storage step ST2). On the other hand, an information identifier S1 for identifying the received information I is generated from the date, time, channel, etc. received by the information identifier generation unit 13 (information identifier generation step ST3), and is stored in the information identifier storage unit 14 in the information storage device 1. Save (information identifier storage step ST4). Further, a storage identifier S2 is generated for which information I was stored or failed to store (step ST5), and this is also stored in the information identifier storage unit 14 (step ST6).
[0052]
When the information storage device 1 and the server device 2 of FIG. 10 are used, the information identifier generation step ST3 is omitted, and instead, the information identifier S1 is also received at the reception step ST1.
[0053]
When a problem such as a hard disk failure or a capacity shortage occurs, the transmission unit 17 reads the information identifier S1 and the storage identifier S2 from the information identifier storage unit 14 as shown in the flowchart of FIG. The receiver identifier S3 is read from the unit 16 (step ST8). Then, for example, the process selection screen shown in FIG. 16 is displayed on a TV display (not shown) connected to the information storage device 1 (step ST9) as an example, and the process reception unit 18 receives the user instruction, for example, the process input device 111. The cursor on the process selection screen (represented by an underline and a symbol> in FIG. 16) is moved through to select a process to be performed on the screen (step ST10). Then, based on the user's instruction, the process accepting unit 18 generates a process identifier S4 (step ST11) and transmits it to the server device 2 provided in the service center (step ST12).
[0054]
On the other hand, on the server device 2 side provided in the service center, as shown in the flowchart of FIG. 17, the receiving unit 21 receives information corresponding to the contents of the information identifier storage unit 14 (step ST13), and the storage identifier S2 (Step ST14), the processing identifier S4 is referred to for restoring the stored information I (step ST15), and if the information I needs to be restored, If the first digit of the process identifier S4 is 1 (the process identifier S4 is 11 or 10), the information I identified by the information identifier S1 is acquired via the network N (step ST17), and the information I is stored in the information The data is stored in the unit 24 (step ST18). For rewriting information I that has failed to be stored, the process identifier S4 is referred to (step ST16). If rewriting is necessary, the last digit of the process identifier S4 is 1 (the process identifier S4 is 11 or 01). If so, the information I identified by the information identifier S1 is acquired via the network N (step ST17), and the information I is stored in the information storage unit 24 (step ST18). Then, the information I that is the contents of the information storage unit 24 is transmitted from the transmission unit 25 to the second reception unit 11b in the information storage device 1 (step ST19). It is confirmed whether there is any information I to be transmitted (step ST20), and if there is, the process returns to step ST13 to accept a new information identifier S1 and repeat the process.
[0055]
Then, the second receiving unit 11b in the information storage device 1 receives the information I, and stores the received information I in the second information storage unit 12b, whereby the contents of the information storage unit 12 are restored.
[0056]
As described above, according to the present embodiment, the restoration of the information I when the information storage unit 12 becomes abnormal due to a failure of the hard disk 106 or a capacity shortage and the information I cannot be read or fails to be written. Or it can be rewritten. Moreover, since the information I exists in the broadcasting station BS, only the information identifier S1 needs to be backed up for restoration or the like.
[0057]
The effect described in the previous stage can be obtained by receiving the information identifier S1 together with the information I in the receiving unit 11 instead of generating the information identifier S1 in the information identifier generating unit 13.
[0058]
Further, since the storage identifier generation unit 15 is separately provided in the information storage device 1 and the storage identifier S2 is stored together with the information identifier S1, the stored information I and the information I that has failed to be stored are easily distinguished. be able to. In the present embodiment, both the information identifier S1 for identifying information stored using the storage identifier S2 and the information identifier S1 for identifying unstored information are stored in the information identifier storage unit 14. However, only the information identifier S1 for identifying the stored information I or the unstored information I may be stored in the information identifier storage unit 14. In this case, the storage identifier S2 and the storage identifier generation unit 15 can be omitted. Even in this case, the stored information I can be selectively rewritten or rewritten with the information I that failed to be written.
[0059]
In the present embodiment, the information storage device 1 side is transmitted to the server device 2 with the information identifier S1 or the information identifier S1 and the storage identifier S2 and a receiver identifier S3 for identifying a receiver who receives the information I. A transmission unit 17 that manages the receiver identifier S3, and a reception unit 21 that receives the transmitted information identifier S1 and storage identifier S2 on the server device 2 side, and refers to the storage identifier S2. An information acquisition unit 22 that acquires information identified by the information identifier S1, an information storage unit 24 that stores the acquired information I, and a transmission unit 25 are provided. The information I transmitted from the transmitting unit 25 is received by the second receiving unit 11b on the information storage device 1 side, and the information I received by the second receiving unit 11b is stored in the second information storing unit 12b. did.
[0060]
With such a configuration, it is possible to make a request online such as rewriting information I that has failed to be restored or stored, and automatically receive the recipient, that is, the individual who is the billing source here. The receiver identifier S3, which is information specifying the information storage device 1, is transmitted to the server device 2 side, and the server device 2 side stores the information I according to the received information identifier S1 and storage identifier S2. The information storage device 1 can receive the information I online and automatically store it, so that it can be stored and stored automatically. The information I to be rewritten can be easily received, which can contribute to the convenience of the user.
[0061]
Note that the management unit 16 may be omitted, and information specifying the receiver may be transmitted by another method, for example, manually inputting the receiver ID. Further, the determination as to whether or not the information I is stored using the storage identifier S2 may be omitted. Further, the transmission unit 25 is omitted, and for example, the contents of the information storage unit 24 are stored in a new hard disk and mailed to each user of the information storage device 1, and the hard disk is attached to the information storage device 1. For example, the information I may be restored or rewritten by a method other than online transmission, or the information I may be directly transmitted without preparing the information storage unit 24. Then, the transmitter 17 may be omitted, and for example, the memory card 108 constituting the information identifier storage unit 14 may be billed by another method such as mailing to a service center.
[0062]
Although the case where the information identifier storage unit 14 is provided in the information storage device 1 has been described so far, as the second embodiment, the information identifier storage unit 23 may be provided on the server device 2 side. This embodiment will be described with reference to the drawings.
[0063]
In this second embodiment, since it is the same as the first embodiment in terms of equipment, the description thereof is omitted. First, each functional block of the information storage system S will be described with reference to FIG.
[0064]
First, the function of the information storage device 1 will be described. In this case, the CPU 101 and the like are operated by a program built in the internal memory 102 and the like, and the reception unit 11, the information storage unit 12, the information identifier generation unit 13, the storage identifier It functions as the generation unit 15, the management unit 16, the transmission unit 17, the processing reception unit 18, the second reception unit 11b, the second information storage unit 12b, and the like.
[0065]
On the other hand, the function of the server device 2 will be described. In this device, the CPU 201 and peripheral devices are operated by a program built in the internal memory 202 or the external storage device 203, and the reception unit 21, the information identifier storage unit 23, the information acquisition It functions as the unit 22, the information storage unit 24, the transmission unit 25, and the like.
[0066]
Hereinafter, each functional block of the information storage device 1 will be described in detail. In the information storage device 1, the reception unit 11, the information storage unit 12, the information identifier generation unit 13, the storage identifier generation unit 15, the management unit 16, and the process reception Since the unit 18, the second receiving unit 11b, and the second information storage unit 12b perform the same functions as those of the first embodiment, the description thereof will be omitted.
[0067]
Instead of providing the information identifier generating unit 13 in the information storage device 1, the receiving unit 11 may receive information I and the information identifier S1 for identifying the information I in advance as a set. A functional block diagram in this case is shown in FIG.
[0068]
The transmission unit 17 receives the information identifier S1 from the information identifier generation unit 13 or the reception unit 11, the storage identifier S2 from the storage identifier generation unit 15, and the receiver identifier S3 from the management unit 16 each time the information I is received. It is for receiving and transmitting to the server device 2, and is configured using the communication interface 109.
[0069]
When a problem such as a hard disk failure or insufficient capacity occurs, only the processing identifier S4 for selecting the processing to be performed by the server device 2 and the receiver identifier S3 are transmitted from the transmission unit 17.
[0070]
Next, each functional block of the server device 2 will be described in detail.
[0071]
The reception unit 21 receives the information identifier S1, the storage identifier S2, and the receiver identifier S3 every time the receiver receives the information I, or when a problem such as a failure of the information storage device 12 or a lack of capacity occurs. This is for receiving the receiver identifier S3 and the process identifier S4, and is configured using the communication interface 206 as in the first embodiment.
[0072]
The information identifier storage unit 23 is for storing the information identifier S1 and the storage identifier S2 received by the receiving unit 21. The stored information identifier S1 and storage identifier S2 are associated with the receiver identifier S3.
[0073]
The information acquisition unit 22 searches the information identifier S1 stored in the information identifier storage unit 23 in association with the receiver identifier S3 from the stored contents of the information identifier storage unit 23, and the information identifier S1 searched as a result is searched for. As in the first embodiment, for example, the information I identified by is searched and acquired on the network N.
[0074]
Hereinafter, the information storage unit 24 and the transmission unit 25 are configured to perform the same functions as those of the first embodiment, and thus description thereof is omitted.
[0075]
Next, the operation of the information system S will be described. Further, flowcharts are shown in FIGS.
[0076]
On the information storage device 1 side, after receiving the information I (step ST1), the information I is stored in the information storage unit 12 (step ST2), and further an information identifier S1 is generated by the information identifier generation unit 13 (step ST3). The steps until the storage identifier S2 is generated by the storage identifier generation unit 15 (step ST5) are the same as those in the first embodiment. Next, after receiving the receiver identifier S3 from the management unit 16 (step ST21), the transmitter 17 provides the service center with the information identifier S1 and the storage identifier S2 corresponding to the received information I together with the receiver identifier S3. The data is sequentially transmitted to the server device 2 (step ST22).
[0077]
On the other hand, on the server device 2 side, as shown in FIG. 21, the information identifier S1 transmitted from the transmission unit 17 is received by the reception unit 21 (step ST23), and these are stored in the information identifier in association with the receiver identifier S3. The data is stored in the unit 23 (step ST24).
[0078]
When a problem such as a hard disk failure or insufficient capacity occurs, on the information storage device 1 side, as an example, as in the first embodiment, a TV display (shown in FIG. 16) connected to the information storage device 1 is displayed. (Step ST9), and the process receiving unit 18 receives a user instruction (Step ST10). Then, based on the user's instruction, the process reception unit 18 generates a process identifier S4 (step ST11), and receives and transmits the receiver identifier S3 from the management unit 16 (step ST12). On the server side 2, as shown in the flowchart of FIG. 22, the receiver identifier S3 and the process identifier S4 are received (step ST25), and the information identifier storage unit 23 associates the receiver identifier S3 with the receiver identifier S3. The stored information identifier S1 is searched from the contents of the information identifier storage unit 23 (step ST26). Thereafter, the process is the same as that after step ST14 of the first embodiment, but at the stage where it is confirmed whether information I to be transmitted remains (step ST20), if information I to be transmitted remains, the process returns to step ST25.
[0079]
As described above, instead of using the information storage device 1 that stores the information identifier S1 and the storage identifier S2 in the information identifier storage unit 14 in the first embodiment, in this embodiment, the management unit 16 that manages the receiver identifier S3. In addition, the information storage device 1 that always includes the transmission unit 17 for transmitting the information identifier S1, the storage identifier S2, and the receiver identifier S3 is used, and the information identifier storage unit 23 is provided on the server device 2 side. All effects similar to those described in the form can be obtained. In addition, since the information identifier storage unit 14 can be omitted from the information storage device 1, the information storage device 1 can be made inexpensive. Furthermore, there is an effect that the information identifier S1 and the storage identifier S2 can be centrally managed by the service center.
[0080]
Even if the transmission unit 17 is omitted from the information storage device 1 and the request for rewriting the information I that has failed to restore or store the information I is made by mail or telephone, the information is sent to the server device 2. If the identifier storage unit 23, the information acquisition unit 22, the information storage unit 24, and the transmission unit 25 are provided, the information identifier S1 corresponding to the requested information I is read from the information identifier storage unit 23, and is hereinafter referred to as the information identifier S1.

Furthermore, if the receiving unit 21 that receives the receiver identifier S3 by manual input or the like is provided, the recipient receiver can be easily identified by the receiver identifier S3. Of course, the information storage unit 24 may be omitted and the information I may be transmitted directly from the transmission unit 25. Alternatively, the transmission unit 25 may be omitted, for example, the contents of the information storage unit 24 may be saved on a new hard disk and The information I may be restored or rewritten by a method other than online transmission, such as mailing to the user of the information storage device 1 and attaching the hard disk to the information storage device 1.
[0081]
The present invention is not limited to the above embodiments. For example, the information I is not transmitted by the satellite SL such as BS / CS digital TV broadcast or data broadcast, but may be transmitted by using a wired cable, a general ground wave, or the like. Further, the information storage unit 12 in the information storage device 1 may use a storage medium other than the hard disk 106. The number of tuners 104a and 104b of the information storage device 1 is not necessarily two, and there is no need to fix the channel of the tuner 104b. Furthermore, it is not necessary to forcibly save the received information I in the information storage unit 12. It is not necessary to distinguish between the provider area and the user area of the information storage unit 12.
[0082]
Furthermore, more generally, as an example of use as a means for recording the history of stored information I, for example, information corresponding to pay information in the information identifier storage unit 14 (or 23) in the information storage device 1 or the server device 2 When it is recorded that the identifier is stored, charging is performed according to the stored information I, or when a problem occurs in the information storage unit 12 such as a failure of the hard disk 106 as a backup service for paid information. Similarly, it is possible to accept a request for restoring the contents of the information storage unit 12 by transmitting the corresponding information identifier S1, storage identifier S2, and receiver identifier S3 to the server device 2 of the service center. Alternatively, it is conceivable to perform a similar backup service for non-paid information.
[0083]
【The invention's effect】
Since the present invention is configured as described above, information that was originally stored when the hard disk failed but could not be read, or information that was not stored due to writing failure due to insufficient capacity of the medium, etc. could be It is possible to restore the wear without placing a heavy burden on the wear.
