On the right side of the content management screen 21, the programs included in the selected folder are displayed in file units.

  For example, when “Dad” and “Mama”, who are users, make a recording reservation for a program, they designate their own folder in the directory tree and make a recording reservation. In addition, when searching for a program to be viewed, the users “daddy” and “mama” want to view by specifying their own folder in the directory tree and displaying a recording list as described later. Search and selection of programs can be performed. In other words, by using the content management screen 21 in FIG. 2, it becomes easy for the users “daddy” and “mama” to manage the program data under their own folders.

  The content management screen 21 shown in FIG. 2 is displayed on the screens of the television receiver 11 and the PC 12, and the user performs operations such as folder selection, file deletion, and file movement on the content management screen 21. can do.

  FIG. 3 is a diagram for explaining a display example of a recording list. The recording list displays a plurality of programs stored in the HDD 13 on the screen of the display means of the television receiver 11 in a list format. The user displays various recording lists as shown in FIG. 3 on the screen of the television receiver 11 by instructing the television receiver 11 with a predetermined command using a predetermined input device such as a remote controller. Can do. Here, the recording list is classified according to a normal display recording list in which all programs are displayed in a list format in a predetermined order, for example, in order of oldest recording date and time, and a classification set or designated in advance by the user. There are two types of recording lists classified by category that are displayed in a list format in a predetermined order. Here, there are three types of recording lists classified by category: days of the week, genres, and serial dramas.

  When the user wants to display a list of all programs in his / her folder, that is, all contents, the user can operate the remote controller 11 c to display the screen 31 on the screen of the television receiver 11. For example, when the user designates the “papa” folder 22 in FIG. 2 and instructs the display of the normal recording list, all programs in the “papa” folder 22 are displayed in a list.

  Further, when the user wants to display a list of recorded programs for each day of the week recorded from all the programs in his / her folder, the user operates the remote controller 11c to display the screen 32 on the screen of the television receiver 11. Can be displayed. The screen 32 is a day-by-day recording list display screen. For example, in the case of “daddy” in FIG. 2, all programs in the “daddy” folder are displayed in a list for each designated day of the week. On the screen 32, each day of the week, which is a classification item lower than the classification item of day of the week as classification information, is displayed in the tab display section 32a in a tab or button (hereinafter referred to as tab) format. Seven tabs are displayed on the tab display section 32a, which is an item display section, corresponding to Monday through Sunday. On the screen 32, the program recorded on the day of the week of the selected tab is displayed in a list in the center of the screen 32 by moving the cursor to the tab of the day of the week to be displayed and selecting it. That is, the selected tab, that is, the program corresponding to the day of the week is displayed on the list display section 32b.

  When the user wants to display a list of recorded programs by genre among all programs in his / her folder, the user operates the remote controller 11c to display the screen 33 on the screen of the television receiver 11. Can be made. The screen 33 is a genre-specific recording list display screen. For example, in the case of “Daddy” in FIG. 2, all programs in the “Daddy” folder 22 are displayed in a list for each genre. On the screen 33, item names of sports, drama, etc., which are classification items lower than the classification item of genre, which is classification information, are displayed on the tab display section 33a in tab format. Four tabs, such as sports, drama, news, and others, are displayed corresponding to the genre name on the tab display section 33a which is an item display section. On the screen 33, by moving the cursor to the tab of the genre to be displayed and selecting it, the programs of the genre of the selected tab are displayed in a list at the center of the screen 33. That is, the program corresponding to the selected tab, that is, the genre is displayed on the list display portion 33b.

  Further, when the user wants to display a list of recorded programs for each of the series drama as a series program among all the programs in his / her folder, the user operates the remote controller 11c to display the screen 34 on the television receiver 11. Can be displayed on the screen. The screen 34 is a recording list display screen for each continuous drama. For example, in the case of “Daddy” in FIG. 2, a list is displayed for each series program, that is, for each continuous drama among all programs in the “Daddy” folder. On the screen 34, each series name, that is, a drama name, which is a classification item lower than the classification item of continuous drama as classification information, that is, a drama name is displayed in a tab format on the tab display unit 34a. Four tabs are displayed on the tab display section 34a, which is an item display section, corresponding to the continuous drama name. On the screen 34, by moving the cursor to the tab of the continuous drama to be displayed and selecting it, a list of programs of the continuous drama on the selected tab is displayed in the center of the screen 34. That is, the program corresponding to the selected tab, that is, the series drama is displayed on the list display unit 34b. Then, the user can select, for example, the number of broadcasts to watch from the list of series programs displayed on the list display unit 34b.

  As described above, when displaying a list of programs that match specified classification information, such as “Sunday” for each day of the week and “Sports” for each genre, contents that match the specified classification information are extracted, The extracted contents are displayed in a list.

  By the way, in order to display the recording list on the list display units 31b, 32b, 33b, and 34b, the meta information of the content must also be acquired. The television receiver 11 receives SI (Service Information) information in addition to video data of a program, that is, content data. Therefore, the television receiver 11 can extract necessary meta information for each program from the SI information.

  Conventionally, by searching all meta files including meta information of all recorded programs, not only the screen 31 but also a recording list for each day of the week, each genre or each continuous drama, such as the screen 32, 33 or 34. Are displayed on the screen of the television receiver 11, but when the number of stored programs increases, it takes time to display each screen in the CPU 11b. For example, in order to display a list of programs recorded on a certain day of the week, all metafiles are searched as search targets using the data of the day of the week as a key, so it takes time to display the recording list.

Therefore, in the present embodiment, the content information file 13c is provided in the HDD 13 in order to display the recording list at high speed.
FIG. 4 is a diagram showing an example of the content information file. The content information file 13c is a tabular table including a file name item column 41, a day item column 42, a genre item column 43, and a serial drama identifier, that is, an ID item column 44. Corresponding to each file name, classification information of day of the week, genre and serial drama ID is stored. Here, it is a case where the user has set the day of the week, the genre, and the continuous drama as the classification information.

The content information file 13c can be set for each folder in the directory tree.
Therefore, when the recording list as shown in FIG. 3 is displayed corresponding to each “dad” or “mama” user, the content information file set for the user's folder is referred to, and each recording shown in FIG. A list is created. Further, for example, if folders “hobby” and “work” are set in the lower hierarchy of the “papa” folder 22, the content information file is also stored in each of the “hobby” and “work” folders. Can also be set. As a result, the above-described recording list of FIG. 3 also becomes a list corresponding to the hierarchy in which the content information file is set, ie, the folder.
That is, the content data and metafile of each program are stored in the HDD 13 corresponding to each specified folder on each predetermined directory tree as shown in FIG.

  When the predetermined meta information is extracted from the SI information after the folder is specified and recording is started, the predetermined classification information extracted from the meta information is added to the content information file 13c in FIG. The For example, it is assumed that the user “daddy” designates his / her folder 22 and makes a recording reservation. When the recording of the program is started in accordance with the recording reservation, the content information file 13c in the folder hierarchy of the user “papa” is designated as the content information file 13c from the meta information regarding the recorded program. If there is information on each item as the classification information, the information on each item is written corresponding to the file name of the program being recorded. In the case of a sports program recorded on Sunday, the file name is “aa1”, “Sunday” is stored in the item 42 of the day, and “Sport” is stored in the item 43 of the genre. For the file name “aa2”, data indicating that the genre is “drama” and the “continuous drama ID” is “01” is stored in the content information file 13c.

  As described above, the content information file 13c is set for each designated hierarchy, and predetermined classification information is stored by being extracted from the meta information.

FIG. 5 is a diagram for explaining a process in which a content information file is created from received program data.
The data received by the antenna 16 includes content data that is data of the program itself and SI information about the content. When a program is recorded, the television receiver 11 stores each content data 51 in the HDD 13 and also stores a metafile 52 including meta information of each content in the HDD 13 in association with each content data 51. To do. As described above, meta information such as a program title, genre, and channel is extracted from SI information. Each content data 51 is stored in the content storage unit 13a, and each metafile 52 is stored in the metafile storage unit 13b.

  The process of storing the content file 51 and the meta file 52 including the meta information in the HDD 13 connected to the network 15 is performed by the CPU 11a. That is, the CPU 11a configures a content information storage unit that stores content data and meta information in an external storage device connected to the network.

  As described above, the classification information corresponding to the item of the content information file 13c is extracted from the meta information, and the extracted classification information is added to the content information file 13c, whereby the content information file 13c. Data is generated.

  Further, the series name information of the continuous drama in the continuous drama information file 13d, which is a series program information file, is also extracted or generated from the SI information. The extracted series name information is also added to the metafile as meta information. In this embodiment, when the user makes a recording reservation, when the recording reservation is made by, for example, specifying a periodic recording reservation, when the first continuous drama is reserved for recording, the identifier of the series program is used. A series ID (described later) is generated, and series name information is extracted. When the scheduled recording is performed for the second time or later, the continuous drum ID is not generated. For example, a program recorded by a regular recording reservation such as from 8:15 to 8:30 in the morning from Monday to Saturday or from 10 to 11 on every Friday night is a series program. To be judged.

  The extraction of the series name information from the SI information may be performed by text analysis, for example, and the series name may be generated from the title information, that is, the program name.

  Processing for extracting predetermined classification information from the meta information and storing it in the content information file 13c and the continuous drama information file 13d of the HDD 13 is performed by the CPU 11a. That is, the CPU 11a extracts predetermined classification information from predetermined meta information about each content, and stores the content classification information stored in the content information file 13c and the continuous drama information file 13d of the external storage device connected to the network. A storage unit is configured.

Using the generated content information file 13c and the continuous drama information file 13d, the recording list classified by classification shown in FIG. 3 is generated and displayed, so that the user can select a program that the user wants to view.
For example, when the user searches for a program to be viewed from among the recorded programs, for example, a recording list as illustrated in FIG. 3 is displayed on the screen of the television receiver 11, and the list is displayed. Therefore, by designating, that is, selecting a program to be viewed, the content data of the program can be read from the HDD 13 via the network 15 and viewed on the television receiver 11.

  For example, when a user wants to audition a program recorded on Sunday, the user supplies an instruction, that is, a command to the television receiver 11 using the remote controller 11c so that the recording list 32 for each day of the week is displayed on the screen. Alternatively, when the user wants to watch one of the recorded dramas, the recording list 33 for each genre is displayed.

  When receiving the command for displaying the recording list for each category, the television receiver 11 extracts data necessary for displaying the recording list from the content information file 13c, and displays the recording list on the screen.

  For example, when the user wants to audition a program recorded on Sunday, a command for displaying a screen 32 that is a recording list display screen for each day of the week is supplied from the remote control 11c to the television receiver 11. The television receiver 11 reads the data of the content information file 13c, generates display data for displaying the screen 32, and displays the tab display portion 32a and the list display portion 32b on the screen. In the screen 32 of FIG. 3, Sunday is selected, and a list of programs recorded on Sunday is displayed in the list display section 32b.

Similarly, for example, when the user wants to audition a recorded sports program, a command for displaying the screen 33 which is a genre-specific recording list display screen is supplied from the remote control 11c to the television receiver 11. The television receiver 11 reads the data of the content information file 53, generates display data for displaying the screen 33, and displays the tab display section 33a and the list display section 33b on the screen. In the screen 33 of FIG. 3, sports are selected, and a list of sports genres is displayed on the list display section 33b.
Similarly, for example, when the user wants to audition a continuous drama program recorded by the user, a command for displaying the screen 34 which is a recording list display screen for each continuous drama is supplied from the remote control 11c to the television receiver 11. The television receiver 11 reads the data of the content information file 13c and the continuous drama information file 13d, generates display data for displaying the screen 34, and displays the tab display unit 34a and the list display unit 34b on the screen. indicate. In the screen 34 of FIG. 3, the series “Traemon” is selected, and a list of programs of the selected series is displayed in the list display section 34b.
When displaying a list of contents that match the specified classification information as described above, the process of extracting content that matches the specified classification information from the content information file 13c based on the specified classification information is as follows: This is performed by the CPU 11a. That is, the CPU 11a extracts a content that matches the specified classification information from the content information file 13c based on the specified classification information when displaying a list of contents that match the specified classification information. Configure.

  Further, the CPU 11a also performs processing for displaying a list of contents that match the specified classification information based on the extracted contents. That is, the CPU 11a configures a list display unit that displays a list of contents that match the specified classification information based on the extracted contents.

  In the case of displaying the recording list for each continuous drama, as shown in FIG. 3, each series name is displayed in a tab format on the tab display unit 34a. For this reason, conventionally, the series name is searched for and extracted from all metafiles, but the process of searching for all metafiles takes time. Therefore, in the present embodiment, it is possible to display at high speed by using a continuous drama information file 13d as described later.

Here, the configuration of the continuous drama information file 13d will be described. FIG. 6 is a diagram illustrating a configuration example of a continuous drama information file. The continuous drama information file 13d is a tabular format including a series drama ID item 24 that is an identifier of a continuous drama, a serial drama series name item 25 that is a series name of a continuous drama, and a recorded content count item 26. It is a table. In the continuous drama information file 13d, information on the number of stored contents is stored corresponding to the series name.
When recording is scheduled for the first time, the series program is recorded for the first time, and a series ID and serial series name are assigned and registered. For the second and subsequent recordings, only the value in the number of contents column is registered. Is incremented.

The continuous drama information file 13d is also set for each hierarchy, that is, for each folder.
Further, as will be described later, data is added to, deleted from, and changed in the continuous drama information file 13d shown in FIG.

FIG. 7 is a diagram for explaining the process of extracting the specified content data and metafile from the content information file 13c.
As shown in FIG. 7, based on the content information file 13c, only the content data 51a and the metafile 52a of the designated classification can be selected.

  As described above, when displaying the recording list classified by category in response to the instruction to display the recording list classified by classification from the user, the CPU 11a is designated by the user or set by default in the designated classification. The content information file 13c is searched for item contents such as “Sunday” and “Sports”, and the corresponding content data 51a and metafile 52a are extracted. Based on the extracted content data 51a and metafile 52a, the CPU 11a displays the recording list on the list display sections 32b, 33b, and 34b.

  When the user selects or designates content to be viewed or reproduced from the displayed recording list, the CPU 11a reads the selected content data 51a from the content storage unit 13a of the HDD 13 and performs reproduction processing. Do.

  As described above, when displaying the recording list for each category, the recording list for each category is displayed based on the data of the content information file 13c and the continuous drama information file 13d. In the above-described example, when displaying the recording lists 32 and 33 for each day of the week and each genre, the recording list for each category is displayed based on the data of the content information file 13c, and the recording list 34 for each continuous drama is displayed. Is displayed based on the data of the content information file 13c and the continuous drama information file 13d.

  When displaying the recording list screen 31 for normal display, all the content data 51 of the content storage unit 13a and all of the metafile storage unit 13b are used without using the data of the content information file 13c and the continuous drama information file 13d. Display data is generated based on the information in the metafile 52. The normal display is a display that can display a recording list of all programs. Therefore, when receiving the command for displaying the normal display recording list, the television receiver 11 displays the program recording list on the list display unit 31b based on the information of all the contents 51 and all the metafiles 52 in the HDD 13. The recording list screen 31 to be displayed is displayed.

  The normal display process is also performed by the CPU 11a. Therefore, the CPU 11a configures an all content extraction unit that extracts all content from all content data and all predetermined meta information stored in the external storage device when displaying a list of all content.

  Note that new data may be added to or deleted from the content information file 13c. FIG. 8 is a diagram for explaining addition and deletion of data in the content information file 13c.

  First, as described above, when recording of a program is started by recording reservation or the like and SI information including attribute information is acquired, a new file name and information on each item are added to the content information file 13c. . Further, the directory tree display screen of FIG. 2 is displayed on the screen of the television receiver 11 or the PC 12, and the file is manipulated to move the file between folders (MOVE). When the destination of the content is reached, a new file name and information on each item are added to the content information file 13c.

  When the file is deleted by operating the file on the directory tree display screen of FIG. 2, the file name of the content and the information of each item are deleted from the content information file 13c. Further, when the file is moved (MOVE) on the directory tree display screen of FIG. 2 and the hierarchy of the content information file 13c becomes the source of the content, the file name of the content and information on each item are displayed. Is deleted from the content information file 13c.

  Note that new data may be added to or deleted from the continuous drama information file 13d. FIG. 9 is a diagram for explaining addition and deletion of data in the continuous drama information file 13d.

  First, as described above, recording of a continuous drama program is started by a recording reservation or the like, and when SI information including attribute information is acquired, for the first recording, the information of the continuous drama ID and the continuous drama series name is displayed. Are added to the continuous drama information file 13d. At this time, the number of contents is 1. Thereafter, when the recording of the same continuous drama program after the second time is disclosed, since the serial drama ID of the continuous drama is already registered in the continuous drama information file 13d, only the number of contents is counted up. Further, the directory tree display screen of FIG. 2 is displayed on the screen of the television receiver 11 or the PC 12, and the file is manipulated to move the file between folders (MOVE). Even when the destination of the content of the serial drama is reached, information on the series ID and series name is newly registered, or the number of contents is counted up.

  In addition, when a file of a continuous drama is deleted by operating the file on the directory tree display screen of FIG. 2, or the file is moved (MOVE) on the directory tree display screen of FIG. When the hierarchy of the information file 13c becomes the movement source of the folder, the number of contents of the continuous drum ID of the file is counted down, and when the number of contents becomes 0 (zero), all the information of the continuous drum ID is It is deleted from the continuous drama information file 13d.

  Therefore, when it is registered for the first time in the continuous drama information file 13d, the number of contents is 1, and after that, when the same series of continuous dramas is recorded, the number of contents is incremented. Thereafter, when the content of the continuous drama is moved or deleted from the hierarchy by moving or deleting, the number of contents is decremented.

  As described above, when the screen 34 of the recording list for each continuous drama for the continuous drama is displayed, each series name is displayed in a tab format on the tab display unit 34a as shown in FIG. In order to display the tab display portion 34a at high speed, the continuous drama information file 13d is used in the present embodiment.

  In the tab display portion 34a, the series name of each serial drama is displayed corresponding to each tab. The CPU 11a can generate the display of the tab display section 34a only by extracting the series name from the continuous drama series name in the continuous drama information file 13d.

Next, a process for registering data in the continuous drama information file 13d when a continuous drama is recorded will be described. FIG. 10 is a flowchart showing an example of the flow of data registration processing in the continuous drama information file 13d.
As described above, when recording of a continuous drama is started by reserved recording, the CPU 11a first determines whether the input program, that is, the content is a continuous drama (step S1). This determination is determined to be a continuous drama when there is a regular recording reservation designation such as recording from 10:00 to 11:00 every Friday as described above during scheduled recording. . If “NO” in the step S1, that is, if it is not a continuous drama recording, the subsequent processing of FIG. 10 is not performed.

  If YES in step S1, that is, if it is a continuous drama recording, information on the series ID and series name is added to the metafile (step S2).

  Next, it is determined whether the program that has started recording is a new series program, that is, whether or not the program has been recorded as a series program for the first time without being recorded as a series program (step S3).

  If YES in step S3, that is, if the program that has started recording is a new series, the continuous drum ID has not yet been assigned to the program, so the serial drum ID and serial drum series name registration processing is performed. (Step S4).

  When NO in step S3, that is, when the recording of the program that has started recording is the second or subsequent recording as a series program, the serial number and serial series name have already been registered for that program, so the count up Is performed (step S5).

  As described above, the contents of the continuous drama information file 13d are added and updated during recording. The processing of steps S3 to S5 is executed by the CPU 11a. The processing of steps S3 to S5 constitutes a series program information storage unit that extracts the series name information of the series program from the attribute information and stores it in the continuous drama information file 13d that is a series program information file of the HDD 13.

  As described above, when the method of displaying the recording list for each category using the content information file 13c and the continuous drama information file 13d is used, the above-described addition or deletion may be performed by the PC 12. If a certain content has been deleted by the PC 12, even if a classified recording list is displayed on the screen of the television receiver 11 based on the content information file 13c, the content does not actually exist There is also a possibility.

  Therefore, when content data is added or deleted from a device other than the television receiver 11, for example, from the PC 12, or when the recording does not end normally, the content information file 13 c and the continuous drama information file are stored. There may be a mismatch between the contents of 13d and the program data actually present in the HDD 13. That is, the content stored in the content information file 13c does not actually exist in all the content existing in the HDD 13, or the content stored in the continuous drama information file 13d does not exist in the content information file 13c. Can occur.

  Therefore, the television receiver 11 according to the present embodiment does not match the content information actually present in the HDD 13 and the information in the content information file 13c, and the content information file 13c and the continuous drama information. If it is not consistent with the file 13d, that is, if the content stored in the content information file 13c does not actually exist in all the content existing in the HDD 13, or stored in the continuous drama information file 13d When the content does not exist in the content information file 13c, the content information file 13c and the continuous drama information file 13d are changed by re-creation or correction.

Next, recording list display processing including data change of the content information file 13c and the continuous drama information file 13d will be described.
The flow of the recording list display process will be described with reference to FIG. FIG. 11 is a flowchart illustrating an example of a flow of a recording list display process. The process of FIG. 11 is executed by the CPU 11a of the television receiver 11. When the user instructs the display list display command to the television receiver 11 by the remote controller 11c, the processing of FIG. 11 is executed. The display processing program is stored in the memory 11b, read at the time of execution, and executed by the CPU 11a.

  First, it is determined whether or not the recording list display command is a classification-specific recording list display command (step S11). In the case of NO in step S11, that is, in the case of the display command of the recording list of the normal display on the screen 31, all information existing in the hierarchy is obtained from all information of the contents data 51 and metafile 52 in the hierarchy, that is, the folder. Content is extracted (step S12). The information of all extracted contents is, for example, all file names.

  In the case of YES in step S11, and in the case of the display command of the recording list according to any of the screens 32 and 33, the CPU 11a determines the specified classification from the information of the content information file 13c of the hierarchy, that is, the folder. The content that matches the information item content, that is, the corresponding content is extracted (steps S13 and S14). Here, step S13 is a case of day of the week, step S14 is a case of genre, and step S5 is a case of continuous drama series.

For example, in steps S13 and S14, the content information file 13c is searched for by default or user-specified item contents such as “Sunday” and “Sports”, and information on the content corresponding to the item contents, for example, the file name is extracted. Is done. Each process of steps S 1 3 and S 14 corresponds to the process of the content extraction unit.

If YES in step S11 and the display command of the recording list for each continuous drama on the screen 34 is displayed, the CPU 11a first checks the consistency of the continuous drama information file 13d, that is, the continuous drama information file 13d. It is checked whether or not the content stored in the content information file 13c exists (step S15).
When the process of step S15 displays a list of contents of the series program of the selected series name, it is confirmed whether or not the contents stored in the continuous drama information file 13d exist in the content information file 13c. Configure the confirmation unit.

  This consistency check is performed by checking whether or not the file name included in the continuous drama information file 13d of the hierarchy exists in the content information file 13c and the number of contents of each file name. Specifically, the consistency is confirmed by comparing the number of contents of each series program stored in the content information file 13c with the number of contents of each series program stored in the continuous drama information file 13d. .

As a result of the consistency check in step S15, it is determined whether or not the continuous drama information file 13d and the content information file 13c are consistent at that time (step S16). If it is determined in step S6 that the continuous drama information file 13d and the content information file 13c are consistent, that is, there is no difference in the number of contents between the two files, YES is determined in step S16, and the processing is as described above. The processes after step S18 are performed.
If NO in step S16, the contents of the continuous drama information file 13d are recreated and re-creation processing is executed (step S17). That is, the continuous drama information file 13d is changed by re-creating from the information of all the metafiles 52 or the content information file 13c in the corresponding hierarchy.
If the processing of steps S16 and S17 is not consistent with the content information file 13c and the continuous drama information file 13d, the contents of the continuous drama information file 13d are recreated or corrected so that the consistency can be achieved. A series program information file changing unit to be changed is configured.

  And CPU11a produces | generates and displays the tab of the tab display part 34a (step S18). The tab display unit 34a displays tabs as options for selecting a series name to be displayed in a list.

  When the processing of step S18 displays the list of series program contents, the series names of a plurality of series programs are displayed on the screen of the television receiver 11 based on the series name information stored in the continuous drama information file 13d. Configure the series name output section to output the series name information for display.

  The CPU 11a extracts content corresponding to the designated series name, that is, the corresponding content from the information of the content information file 13c of the hierarchy, that is, the folder (step S19).

  When the corresponding content is extracted in steps S13 to S19, a rearrangement process is performed (step S20). In this rearrangement process, the extracted contents are rearranged in a predetermined order, for example, in the order from the newest recording date or the oldest. As a result, for example, a list in which file names are rearranged in order of recording date and time is obtained.

  The processing of steps S19 to S22 is performed to display the list display information in order to display the list of the contents of the series program having the series name selected from the plurality of series names in the tab display section 34a displayed by the series name output section. A list display information output unit for output is configured.

  Next, the CPU 11a acquires information on the content data 51a and the metafile 52a corresponding to the rearranged file names from the content storage unit 13a and the metafile storage unit 13b (step S21).

  Then, the CPU 11a generates data for each of the screens 32, 33, and 34 using the acquired content data 51a and the information of the metafile 52, and the recording as the screens 32, 33, and 34 in FIG. A list screen is displayed (step S22). Steps S21 and S22 correspond to the processing of the list display information output unit.

  Further, after step S12, the CPU 11a checks the consistency of the content information file 13c (step S23).

  This consistency check is to confirm whether or not the file name included in the content information file 13c in the hierarchy exists in all the contents extracted in step S12.

  As a result of the consistency check in step S23, it is determined whether or not the content existing in the hierarchy at that time is consistent with the content information file 13c (step S24). If it is determined in step S24 that the content existing in the hierarchy is consistent with the content information file 13c, YES is determined in step S24, and the processing is performed from step S20 described above.

If NO in step S24, the content information file 13c is recreated and re-creation processing is executed (step S25).
The content information file 13c is changed by re-creating from the information of all the contents extracted in step S12.
In addition, when the changed part, such as deletion, is known, the content may be changed by correcting the content information file 13c based only on the data of the part.

  The processing of steps S23 and S24 is performed by the CPU 11a. Therefore, after the processing of steps S23 and S24 by the CPU 11a extracts all the contents, the confirmation unit for confirming whether or not the contents stored in the content information file 13c exist in all the extracted contents. Configure.

  Further, the process of step S25 is also performed by the CPU 11a. Therefore, when the content stored in the content information file 13c does not exist in all the extracted contents, the process of step S25 by the CPU 11a is recreated or modified to change the content information file. The content information file changing unit is configured.

  As described above, since the content information file 13c and the continuous drama information file 13d are re-created only when there is a mismatch, the management of the content information file 13c and the continuous drama information file 13d is efficient.

  In the case of a conventional television receiver, hard disk recorder, etc. in which content such as a broadcast program is stored in a built-in hard disk device, the data of the hard disk device is rewritten only by the television receiver, etc. Etc., the result of the deletion or the like is reflected in the folder management, database management system or the like of the television receiver or hard disk recorder. This is because there is only one table for managing content.

  However, if the storage device that stores the content is an external storage device that is connected via a network as described above, and is an external storage device that can also be accessed from the outside, the content stored in the external storage device However, content stored in the external storage device may be deleted by another device connected to the network, for example, a PC.

  In such a case, when a user displays a recording list to select a content to be viewed from a plurality of contents stored in an external storage device in a television receiver or the like, among the candidates in the recording list There may be content that has already been deleted. If the content of the displayed recording list does not match the content of the content actually stored in the external storage device, the user cannot appropriately search for the content using the recording list.

  On the other hand, according to the above-described television receiver according to the present embodiment, a recording list can be displayed at high speed when content is stored in an external storage device accessible from other external devices. At the same time, even when there is a change in data in the external storage device such as deletion of content, the content list can correctly display the recording list corresponding to the change in the data.

  As described above, according to the television receiver according to the present embodiment, when content is stored in an external storage device connected to a network and accessible from other external devices, recording of a desired classification is performed. The list can be displayed at high speed.

  In the above-described embodiment, the television receiver has been described as an example of the content storage management device. However, the content storage management device may not be a television receiver, but may be a tuner device. You may implement | achieve by giving the apparatus mentioned above to the apparatus which has tuners, such as a box.

  In the above example, the external storage device is described as a hard disk device connected to a network and accessible from the outside, but may be a PC equipped with a storage device or the like.

  Furthermore, in the above-described embodiment, the content of the program received from the antenna has been described as an example. However, the input content may be content distributed via a network.

  Note that the code of the program for executing the operations described above is entirely or partly stored as a computer program product on a portable medium such as a floppy (registered trademark) disk or CD-ROM, or on a storage device such as a hard disk. Recorded or memorized. The code of the program is read by the computer, and all or part of the operation is executed. Alternatively, all or part of the program can be distributed or provided via a communication network. The user can easily realize the content storage management device of the present invention by downloading the program via a communication network and installing it on a computer, or installing it from a recording medium to a computer.
