  FIG. 1 is a block diagram showing a configuration example of an information processing system to which the present invention is applied. In this information processing system, an information processing apparatus 1 and a mirror server 3 are connected via a network 2.

  The information processing apparatus 1 is composed of, for example, a hard disk recorder installed at home, and selects, detects, and detects a signal of a predetermined channel from an RF (Radio Frequency) signal received by the antenna 51 (FIG. 3). Then, after demodulating and descrambling the transport stream (TS), a predetermined stream is extracted. Then, the information processing apparatus 1 performs predetermined video processing on the extracted video data, displays the obtained image on the video display device 53 (FIG. 3), and performs predetermined audio on the extracted audio data. Processing is performed, and the obtained sound is output from the sound output device 54 (FIG. 3).

  Further, as shown in FIG. 2, the information processing apparatus 1 stores management information 10 including the preference value 11 and the state information 12 in the recording medium 39 (FIG. 3).

  The preference value 11 is information calculated based on an operation performed on the content by the user or content meta-information. For example, the preference value 11 is calculated based on the recording date / time of the content, the viewing time (reproduction time), the number of times of reproduction, the operation history, or preference information. The preference value 11 calculated from the user operation is clearly expressed by changing the numerical value reflected for each type of operation performed by the user. The preference value 11 calculated from the meta information clearly represents the preference value based on keyword information that matches or approximates the user preference.

  The status information 12 is, for example, information related to the operation (status) of the recording medium 39, and includes the total number of writes, the total number of reads, the read error occurrence rate such as UNC (UNCORRECTABLE ERROR), the number of power on / off, and the slow response. And the number of alternative sector replacement processes.

  The information processing device 1 selects content important for the user based on the preference value 11 or the status information 12 and backs up the content to the mirror server 3 via the network 2.

  Furthermore, the information processing apparatus 1 acquires information regarding the content backed up by the mirror server 3 via the network 2 and creates a list of content.

  The mirror server 3 is composed of a hard disk drive, for example, and records content supplied from the information processing apparatus 1 via the network 2.

  FIG. 3 is a block diagram illustrating an internal configuration example of the information processing apparatus 1.

  A CPU (Central Processing Unit) 21 executes a program stored in the memory 22, and each unit connected to the bus 43 according to a signal supplied from a U / I (User / Interface) control unit 23. To control the operation. Further, the CPU 21 stores the management information 10 (FIG. 2) including the preference value 11 associated with the content and the status information 12 related to the operation of the recording medium 39 based on various operations by the user. It is supplied to the recording medium 39 via F38 and recorded there. The memory 22 appropriately stores programs and data necessary for the CPU 21 to execute various processes.

  The U / I control unit 23 receives infrared rays from the remote controller 52 and outputs a signal corresponding to the user operation obtained by demodulation to the CPU 21.

  The tuner 24 selects, detects and demodulates the RF signal received by the antenna 51 under the control of the CPU 21 and outputs a transport stream (TS) broadcast on a predetermined channel to the descrambler 25.

  The descrambler 25 generates a scramble key using data stored in the IC card 37 inserted in the card I / F 36, and releases the scramble of the transport stream supplied from the tuner 24. The transport stream descrambled by the descrambler 25 is supplied to the demultiplexer 26.

  The demultiplexer 26 extracts a predetermined stream from the transport stream supplied from the descrambler 25 under the control of the CPU 21, and the extracted stream (packets constituting the stream) is a video decoder 27, an audio decoder 30, and a memory 31. Output to. Specifically, Video PES (Packetized Elementary Stream) data or ES (Elementary Stream) data, Audio PES data or ES data, and also Section data are extracted by the PID (Packet ID) set by the CPU 21, and Video PES is extracted. The data or ES data is output to the video decoder 27, the audio PES data or ES data is output to the audio decoder 30, and the section data is output to the memory 31, respectively.

  When the demultiplexer 26 records the content on the recording medium 39, the demultiplexer 26 uses the obtained Video PES data and Audio PES data (content) to the scrambler 32, the information detection unit 33, the buffer 34, and the recording medium I / F 38. To the recording medium 39.

  The video decoder 27 decodes the video PES data or ES data (video packet) supplied from the demultiplexer 26 and outputs the obtained video data to the multiplexer 28.

  The multiplexer 28 performs predetermined image processing, D / A (Digital to Analog) conversion, and the like on the video data supplied from the video decoder 27, and causes the video display device 53 to display a content image. Further, the multiplexer 28 causes the video display device 53 to display a predetermined image based on the graphics data supplied from the graphics control unit 29.

  The graphics control unit 29 generates graphics data of an image to be displayed on the video display device 53 according to control by the CPU 21, and outputs the generated graphics data to the multiplexer 28.

  The audio decoder 30 decodes the audio PES data or ES data (audio packet) supplied from the demultiplexer 26 and outputs the obtained sound from the sound output device 54.

  The memory 31 stores Section data including a channel selection operation and additional information supplied from the demultiplexer 26. This Section data is read appropriately by the CPU 21.

  The scrambler 32 scrambles the Video PES data and Audio PES data (contents) supplied from the demultiplexer 26 using a predetermined key, and the obtained data passes through the buffer 34 and the recording medium I / F 38. Is supplied to the recording medium 39 and recorded there.

  The information detection unit 33 detects reproduction procedure information and reproduction management information from the Video PES data and Audio PES data supplied from the demultiplexer 26, and supplies the reproduction procedure information and reproduction management information to the recording medium 39 via the buffer 34 and the recording medium I / F 38. Let it be recorded there.

  The descrambler 35 generates a predetermined key for descrambling, and releases the scramble of the content read from the recording medium 39 via the recording medium I / F 38 and the buffer 34. The transport stream that has been descrambled by the descrambler 35 is output to the video decoder 27 and the audio decoder 30.

  In addition, when the content recorded on the recording medium 39 is reproduced, the descrambler 35 outputs the content read from the recording medium 39 via the recording medium I / F 38 and the buffer 34 to the video decoder 27 and the audio decoder 30. To do. The content read at this time is determined based on the reproduction management information and the reproduction procedure information recorded on the recording medium 39.

  The card I / F 36 supplies the data read from the IC card 37 to the descrambler 25.

  The recording medium I / F 38 outputs the data read from the recording medium 39 to the video decoder 27 and the audio decoder 30, or supplies the data supplied from the demultiplexer 26 to the recording medium 39.

  The recording medium 39 is composed of, for example, an HDD (Hard Disk Drive) and records data supplied via the recording medium I / F 38. The recording medium 39 also stores the management information 10 shown in FIG.

  The drive 40 drives the removable medium 41 attached to the drive 40 to record the data supplied via the bus 43 in the removable medium 41 and the data (program stored in the removable medium 41). Read) and output it onto the bus 43. The removable medium 41 is, for example, a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory.

  The communication control unit 42 performs communication with the mirror server 3 connected via the network 2.

  FIG. 4 is a block diagram illustrating a functional configuration example of the information processing apparatus 1. The functional configuration example shown in FIG. 4 is realized by the CPU 21 executing a predetermined program stored in the memory 22.

  The information management unit 61 calculates the preference value 11 based on various operations on the content by the user and the meta information of the content, and sets it to the content. In addition, the information management unit 61 acquires the state information 12 regarding the operation (status) of the recording medium 39. Then, the information management unit 61 records and manages the management information 10 including the preference value 11 and the state information 12 on the recording medium 39.

  The content selection unit 62 sets the ranking for each content using the preference value 11 recorded in the recording medium 39, and then the content whose preference value 11 is equal to or higher than a predetermined reference value or the upper number of the preference value 11 The individual contents are selected, and the backup processing unit 65 performs backup processing of the selected contents.

  The state check unit 63 checks (inspects) the state of the recording medium 39 based on an instruction from the user or every predetermined time (periodically). As a result of the check, if it is determined that a further detailed check is necessary, the state check unit 63 presents (notifies) the check result to the presenting unit 66 and then causes the sector check unit 64 to display the entire surface of the recording medium 39 as the detailed check. Let me check.

  The sector check unit 64 checks the entire surface of the recording medium 39 (that is, checks for errors for each sector) under the control of the state check unit 63. As a result of the overall check, the sector check unit 64 retains information on a sector with a long error or read time (sector position, data recorded there, etc.) and needs to back up the content recorded in that sector. Judge whether there is. If it is determined that backup is necessary, the sector check unit 64 causes the backup processing unit 65 to perform backup processing of the corresponding content.

  The backup processing unit 65 compares the capacity of the content scheduled for backup notified from the content selection unit 62 or the sector check unit 64 with the free capacity of the backup destination (in this case, the mirror server 3), and the free capacity of the backup destination. It is determined whether or not there is enough. When it is determined that the backup destination has sufficient free space, the backup processing unit 65 performs backup processing. On the other hand, if it is determined that the free space at the backup destination is insufficient, the backup processing unit 65 causes the presenting unit 66 to show that fact (error message).

  When the user selects a content to be preferentially backed up when the backup destination has insufficient free space, the backup processing unit 65 selects the priority among the content already backed up in the mirror server 3. The content having a low content is deleted, and the content selected by the user is backed up.

  Furthermore, when the backup destination has insufficient free space and the operation mode of the information processing apparatus 1 is set to Auto, the backup processing unit 65 includes the content already backed up to the mirror server 3. The content with a low preference value is deleted and the content is backed up.

  The presenting unit 66 causes the video display device 53 to display a screen (check result) for presenting (notifying) to the user on the basis of the check result by the state check unit 63, and if necessary, the corresponding sound is sounded. Output from the output device 54. As described above, when it is determined that the detailed check is necessary, the check result is displayed on the video display device 53, so that the user can see the details of the recording medium 39 by looking at the screen displayed here. It can be understood that a check (ie, a full check) is performed.

  Further, the presenting unit 66 displays a screen for displaying to the user (an error message indicating that the backup destination has insufficient free space) on the video display device 53 based on the message notified from the backup processing unit 65. Display. As described above, when it is determined that the free capacity of the backup destination is insufficient, an error message indicating insufficient capacity is displayed on the video display device 35. The user can grasp the shortage of the free space at the backup destination and can select the content to be preferentially backed up.

  Next, the periodic backup processing executed by the information processing apparatus 1 will be described with reference to the flowchart of FIG. This process is started every predetermined time (periodically).

  In step S <b> 1, the content selection unit 62 reads the preference value 11 recorded on the recording medium 39, and ranks the recorded content using the preference value 11. In step S <b> 2, the content selection unit 62 selects the content having the preference value 11 equal to or higher than the predetermined reference value or the top several contents of the preference value 11 from the content ranked in the process of step S <b> 1. However, content that has already been backed up is omitted from the selection target.

  In step S3, the backup processing unit 65 performs a backup process of the content selected in the process of step S2. The details of this backup processing will be described later with reference to the flowchart of FIG. 6, and the backup processing of the selected content to the mirror server 3 is performed by this processing.

  By the above regular backup processing, content with a high preference value is automatically backed up on the mirror server 3. Thus, the user can automatically cause the mirror server 3 to back up content that is highly important to the user among the content recorded on the recording medium 39 of the information processing apparatus 1.

  Next, the details of the backup processing in step S3 in FIG. 5 will be described with reference to the flowchart in FIG.

  In step S11, the backup processing unit 65 calculates the capacity of the content to be backed up selected in the process of step S2 in FIG. In step S12, the backup processing unit 65 confirms the free space of the recording medium of the mirror server 3 that is the backup destination.

  In step S13, the backup processing unit 65 determines whether the backup destination free space confirmed in the processing in step S12 is larger than the backup planned content capacity calculated in step S11, and the backup destination free space is determined. When it is determined that the capacity is larger than the capacity of the content scheduled to be backed up, the process proceeds to step S14, and the backup process of the content scheduled to be backed up (that is, the content selected in the process of step S2 in FIG. 5) to the mirror server 3 is performed. .

  Specifically, for example, the content recorded on the recording medium 39 is supplied to the mirror server 3 via the communication control unit 42 and the network 2 as it is and backed up (recorded) there. Also, for example, after the content recorded on the recording medium 39 is scrambled by the scrambler 32, it is supplied to the mirror server 3 and backed up there. Further, for example, when the mirror server 3 is configured with a plurality of recording media, the content recorded on the recording medium 39 is divided into a plurality of contents and then backed up to the plurality of recording media. Furthermore, for example, content that requires copy control is backed up using the move function (that is, all the content in the recording medium 39 that has been copied is erased or invalidated while being copied to the mirror server 3). ).

  In addition to the above-described backup method, for example, the content recorded on the recording medium 39 is divided into a plurality of contents, and each content is scrambled by the scrambler 32 and then supplied to the mirror server 3. Of course, it is also possible to combine backup methods such as being backed up.

  On the other hand, if it is determined in step S13 that the free capacity of the backup destination is smaller than the capacity of the content to be backed up, the process proceeds to step S15, and the backup processing unit 65 has already been backed up to the backup destination (mirror server 3). The content preference value and the preference value of the content scheduled to be backed up are compared to give a ranking.

  In step S16, the backup processing unit 65 determines whether there is content that is lower than the preference value of the content to be backed up among the content that has already been backed up to the backup destination, and the content that is backed up to the backup destination If it is determined that there is content lower than the preference value of the content scheduled to be backed up, the process proceeds to step S17.

  In step S17, the backup processing unit 65 determines whether or not the operation mode of the information processing device 1 is set to Auto, and if it is determined that the operation mode of the information processing device 1 is set to Auto, Proceeding to S18, among the content already backed up at the backup destination, the content of the content scheduled for backup is deleted in order from the content with the lower preference value, and the backup processing of the content with the higher preference value scheduled for backup is performed. .

  After the process of step S14 or step S18, the process proceeds to step S19, where the backup processing unit 65 is backed up to the meta information of the content recorded on the recording medium 39 as the copy source and the mirror server 3 as the backup destination. Associate content. In other words, at the time of backup, the content is connected between the information processing apparatus 1 and the mirror server 3.

  In step S17, when it is determined that the operation mode of the information processing apparatus 1 is not set to Auto, that is, set to Normal, the backup processing unit 65 indicates that the backup destination has insufficient free space. (Error message) is supplied to the presentation unit 66, and the process proceeds to step S20.

  In step S <b> 20, the presentation unit 66 causes the video display device 64 to display a screen for presentation (notification) to the user based on the message supplied from the backup processing unit 65. The screen presented here includes, for example, a message indicating that there is not enough free space at the backup destination, and a dialog prompting deletion of low-priority content among the content already backed up at the backup destination Etc. are included.

  After the process of step S19, after the process of step S20, or when it is determined in step S16 that there is no content lower than the preference value of the content to be backed up among the content backed up at the backup destination, The backup process is terminated.

  As a result of the above backup processing, when the free space at the backup destination is larger than the content to be backed up, the backup processing is automatically performed. In addition, when the backup destination has insufficient free space, there is content with a low preference value at the backup destination, and the backup destination preference value is automatically set even when the operation mode is set to Auto. After the low content is deleted, the backup process is performed. Accordingly, the user can automatically cause the mirror server 3 to back up content that is highly important to the user among the content recorded on the recording medium 39 of the information processing apparatus 1.

  Furthermore, when there is insufficient free space at the backup destination, if there is content with a low preference value at the backup destination and the operation mode is set to Normal, the deletion of the backup destination content is prompted. A screen can be presented to the user. As a result, the user can cause the mirror server 3 to back up new content by selecting and deleting content that has been determined to be low in priority (unnecessary) from content that has already been backed up to the mirror server 3. It becomes possible.

  In step 19, the information processing apparatus 1 associates the meta information of the content recorded on the recording medium 39 that is the copy source with the content that is backed up on the mirror server 3 that is the backup destination. It is also possible to acquire information about the backed up content via the network 2 and create and display a content list.

  Next, the periodic hard disk drive (HDD) status check process executed by the information processing apparatus 1 will be described with reference to the flowchart of FIG. This process is started, for example, when the user operates the remote controller 42 to instruct the hard disk status check process, or at predetermined time intervals (periodically).

  In step S31, the state check unit 63 reads the management information 10 stored in the recording medium 39, and determines from the state information 12 included in the management information 10 whether or not UNC (UNCORRECTABLE ERROR) has occurred. If it is determined that UNC has occurred, the process proceeds to step S32 to diagnose that UNC has occurred in the recording medium 39.

  If it is determined in step S31 that UNC has not occurred, or after the process of step S32, the process proceeds to step S33, and the state check unit 63 further determines the power from the state information 12 of the read management information 10. It is determined whether or not the number of On / Off exceeds the spec. If it is determined that the number of Power On / Off exceeds the spec, the process proceeds to step S34, and the number of Power On / Off of the recording medium 39 exceeds the spec. Diagnose that.

  In Step S33, when it is determined that the number of Power On / Off does not exceed the specification, or after the process of Step S34, the process proceeds to Step S35, and the state check unit 63 further determines the state of the read management information 10 It is determined from the information 12 whether or not sector replacement or replacement processing has occurred. If it is determined that sector replacement or replacement processing has occurred, the process proceeds to step S36, where the sector replacement or replacement processing is performed on the recording medium 39. Diagnose as occurring.

  If it is determined in step S35 that the sector replacement or replacement process has not occurred, or after the process of step S36, the process proceeds to step S37, and the state check unit 63 further reads the state information of the management information 10 that has been read. 12, it is determined whether or not there are many Slow Responses. If it is determined that there are many Slow Responses, the process proceeds to Step S <b> 38 to diagnose that the Slow Response frequency of the recording medium 39 is high.

  If it is determined in step S37 that the Slow Response is not large, or after the process of step S38, the process proceeds to step S39, and the state check unit 63 adds the various data diagnosed in steps S32, S34, S36, and S38. Based on this, the state of the hard disk drive (that is, the recording medium 39) is determined.

  In step S40, the state check unit 63 determines whether or not a detailed check of the hard disk drive is further necessary as a result of the determination in the process of step S39, and determines that the detailed check is necessary. It supplies to the presentation part 66 and progresses to step S41.

  In step S <b> 41, the presentation unit 66 causes the video display device 53 to display a screen for presentation (notification) to the user based on the check result supplied from the state check unit 63. The screen presented here includes, for example, a message indicating that a detailed check of the hard disk drive is necessary.

  In step S <b> 42, the sector check unit 64 performs a full surface check process for the recording medium 39.

  Here, with reference to the flowchart of FIG. 8, the details of the entire surface check process in step S42 of FIG. 7 will be described.

  In step S51, the sector check unit 64 reads the status after reading a predetermined sector of the recording medium 39. In step S52, the sector check unit 64 determines whether or not there is an error in the sector read in the process of step S51. If it is determined that there is an error in the sector, the process proceeds to step S53, and information on the error sector ( The sector position and the data recorded there).

  In step S52, when it is determined that there is no error in the read sector, or after the process of step S53, the process proceeds to step S54, and the sector check unit 64 further determines whether the read time of the read sector is long. If it is determined that the read time is long, the process proceeds to step S54, and information on the error sector is held.

  If it is determined in step S54 that the read time of the read sector is not long, or after the process of step S55, the process proceeds to step S56, where the sector check unit 64 determines whether the entire check of the recording medium 39 has been completed. That is, it is determined whether or not reading of all sectors has been completed. If it is determined that the full check has not been completed yet, the process returns to step S51 and the above-described processing is repeatedly executed.

  If it is determined in step S56 that the full check of the recording medium 39 has been completed, the process proceeds to step S57, and the sector check unit 64 narrows down the corresponding content from the information on the error sector held in steps S53 and S55. At the same time, we demand the importance of errors.

  In step S58, the sector check unit 64 determines whether backup of the corresponding content narrowed down in step S57 is necessary. If it is determined that backup is necessary, the sector check unit 64 proceeds to step S59, and the backup processing unit 65 causes the corresponding content to be backed up. That is, the backup process of FIG. 6 described above is executed, and the backup process of the corresponding content to the mirror server 3 is performed.

  On the other hand, if it is determined in step S58 that it is not necessary to back up the corresponding content narrowed down in the process of step S57, the backup process is not performed and the full check process is terminated as it is. Also, if the corresponding content cannot be narrowed down as a result of the narrowing down performed in step S57, the full check process is ended.

  In addition, when it is determined in step S58 that the error importance level obtained in step S57 is high, the backup process is not performed and the user is notified that the error importance level is high. Thereafter, the full check process is terminated.

  The contents recorded in the error sector are automatically backed up by the above-described regular hard disk drive status check process and full-screen check process. Accordingly, the user can automatically cause the mirror server 3 to back up the content recorded in the error sector of the recording medium 39 of the information processing apparatus 1 without performing a special operation.

  As described above, based on the preference value 11 set for the content and the status information 12 of the recording medium 39, the content important for the user is selected and automatically backed up to the mirror server 3. The capacity of the recording medium 3 can be reduced, and the backup time can be shortened.

  Further, based on the preference value 11 and the status information 12, not only the content important for the user is selected and automatically backed up, but also the content selected by the user can be backed up.

  If the content recorded in the error sector cannot be specified from the status information 12 of the recording medium 39, the user may be requested to make a voluntary backup.

  In the above description, the mirror server 3 has been described as being a hard disk drive connected via the network 2, but the present invention is not limited to this, for example, other servers connected via the network 2. A recording medium (for example, a hard disk recorder) in the apparatus is used as a mirror server, or a recording medium different from the recording medium 39 is newly provided in the information processing apparatus 1 and used as a mirror server. Alternatively, the removable medium 41 inserted into the drive 40 may be used as a mirror server.

  The series of processes described above can be executed by hardware, but can also be executed by software.

  When a series of processing is executed by software, a program constituting the software may execute various functions by installing a computer incorporated in dedicated hardware or various programs. For example, it is installed from a network or a recording medium into a general-purpose personal computer or the like.

  As shown in FIG. 3, the recording medium is separated from the apparatus main body by a removable medium 41 such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory distributed to provide a program to the user. In addition to being configured, it is configured by a hard disk or the like included in the memory 22 or the recording medium 39 in which a program is provided, which is provided to the user in a state of being preinstalled in the apparatus main body.

  In the present specification, each step includes not only processing performed in time series according to the described order but also processing executed in parallel or individually, although not necessarily performed in time series.

  Further, in this specification, the system represents the entire apparatus composed of a plurality of apparatuses.
