(First embodiment)
FIG. 1 is a block diagram showing the configuration of an example of a recording / playback apparatus according to the present invention. FIG. 1 shows an optical disk apparatus A that uses a hard disk and an optical disk as recording media as an example of a recording / playback apparatus according to the present invention. An optical disc apparatus A shown in FIG. 1 includes a tuner unit 1, a data processing unit 2, a control unit 3, a recording unit 4, a memory 5, and an OSD (On Screen Display) generating unit 6 (recording information display generating means). An external output unit 7 and an operation input unit 8.

  The tuner unit 1 is connected to an antenna Ant arranged outside the optical disc apparatus A. And the radio wave (broadcast wave) of the frequency band (channel) decided for every communication carrier is received via the antenna Ant. In the following description, it is assumed that a digital broadcast wave is received. The tuner unit 1 includes an internal demodulation unit, extracts (detects) encoded data (for example, MPEG-2) from the broadcast wave, and converts the encoded data into a data processing unit. Send to 2. The encoded data is obtained by multiplexing a plurality of data including video data, audio data, and additional data.

  The data processing unit 2 includes a decoder unit 21, an encoder unit 22, and an additional information extraction unit 23 (information extraction means).

Depending on the user, the recorded title may be recognized according to the recording date and time, and this is used for selecting the recorded title. The recording date and time display unit Tm may record the time of actual recording by multiplexing the recording data and use the data of that time. Further, the additional data of the recording data includes data of the broadcast date and time, and the broadcast date and time may be displayed on the recording date and time display unit Tm as the recording date and time. Furthermore, in the recording date and time display unit Tm shown in FIG. 2, only the date and the time when the recording was started are displayed. However, the present invention is not limited to this. The time from the start to the end of the broadcast may be displayed.

  As shown in FIG. 2, a title information display section Ti is provided on the right side of the recording date / time display section Tm of the recording title list display M1. The title information display section Ti displays a title name (broadcast program name) of a recorded title and a character string of a specified number of characters.

  The title information display section Ti can display character strings in a plurality of levels (here, 3 levels), the title name of the recording title is displayed in the top level, and the specified number of characters in the bottom 2 levels. Columns can be displayed. In the lower two stages of the title information display section Ti, an outline of the recording title (syntax, corner name, performer, etc.) normally stored in the additional data is displayed.

  In the recorded title list display M1, a recorded title is selected by an input from the operation input unit 8. When a recording title is selected in the recording title list display M1, the cursor Cs is moved to select a desired recording title.

Further, the number of recorded titles displayed at a time may be automatically changed according to the size of the display Dp on which the recorded title list display M1 is displayed.

  The optical disc apparatus A can display the recorded title list as described above. The operation of the optical disc apparatus A when displaying a list of recorded data will be described below with reference to a flowchart. FIG. 3 is a flowchart showing the operation of the recording / playback apparatus when the list display shown in FIG. 2 is performed.

  In the optical disc apparatus A, a list of recorded titles recorded in the recording unit 4 is displayed according to an instruction from the user. Therefore, when the control unit 3 confirms that the user has input an instruction to display a list via the operation input unit 8 (step S11), the control unit 3 starts displaying the recorded title list. In step S11, a list of recorded titles of the folder selected by the user (here, the A folder in the hard disk drive unit 41 shown in FIG. 2) is displayed. Therefore, the control unit 3 detects all the recorded data included in the selected folder (A folder) in the hard disk drive unit 41 of the recording unit 4 (step S12).

  Thereafter, the control unit 3 sends the recorded data to the data processing unit 2, and the decoder unit 21 decodes the video data, audio data, and additional data. Then, a thumbnail image (still image) is extracted from the video data for each recording data, and the additional information extracting unit 23 extracts data necessary for the recording title list display M1, such as a broadcast channel, recording date and time, and title information, from the additional data. (Step S13). Then, these extracted data are sent to the OSD generation unit 6 (step S14).

  The control unit 3 operates the OSD generation unit 6 to generate the recorded title list display M1. At this time, the control unit 3 sends the display image of the recorded title list display M1 stored in the memory 5 to the OSD generation unit 6 (step S15). The OSD generation unit 6 combines the display image received from the memory 5 and data corresponding to the thumbnail image display unit Tn, the channel display unit Cn, the recording date and time display unit Tm, and the title information display unit Ti for each recording data ( Step S16). At this time, the display of the recording title displayed in the recording title list display M <b> 1 is associated with the recording data recorded in the recording unit 4.

  The OSD generation unit 6 sends the generated image data of the recorded title list display M1 to the external output unit 7, and the external output unit 7 sends the image data of the recorded title list display M1 to the display Dp (step S17). Thereby, the recorded title list display M1 is displayed on the display Dp (step S18).

  The user selects a desired recording title while viewing the recorded title list display M1 displayed on the OSD. The control unit 3 detects the recorded title to which the cursor Cs on the recorded title list display M1 is applied from the operation input of the operation input unit 8 (step S110). The control unit 3 operates the additional information extraction unit 23 of the data processing unit 2 to extract caption information from the additional data (step S111).

  Then, the data processing unit 2 sends the caption data to the OSD generation unit 6 in accordance with the instruction from the control unit 3 (step S112). The OSD generation unit 6 follows the instruction from the control unit 3 and displays the subtitle display unit Lt of the recorded data selected in the recorded title list display M1 (the cursor Cs is hit) (lower two levels of the title information display unit Ti). In addition, the subtitles are combined so as to be sequentially sent and displayed (step S113).

  Since the subtitle is to display the content of the recorded title in characters, the user can grasp the content of the recorded title by reading the subtitle. In this way, by displaying subtitles in the recorded title list display M1, it is possible to assist the user in selecting the recorded title. In addition, in a program (for example, news, variety show, sports, etc.) whose thumbnail images are very similar, recorded titles that are difficult to distinguish by thumbnail images may be displayed side by side. Even in such a case, the user can easily determine the difference in the program content of the recorded data by checking the subtitles, so that the user can easily find a desired recorded title.

  The subtitles may be sent automatically, or may be sent faster or later according to the user's request. Furthermore, the subtitles may be sent one character or a plurality of characters at a time, or may be sent for each line or a plurality of lines.

  Furthermore, subtitles may be fixed. In the case of a recorded title list display in which no subtitles are sent, subtitles for a predetermined period may be displayed. In this case, as a caption to be displayed, a caption having a predetermined number of characters from the beginning (for example, the number of characters that can be accommodated in the caption display unit Lt) may be used.

  The optical disc apparatus A of the present embodiment is configured to receive broadcast waves of digital broadcasting (terrestrial, BS, CS, cable television, etc.), but may be configured to receive analog broadcast waves. . In this case, an analog tuner may be provided as the tuner unit 1 and the data may be recorded in the recording unit 4 after being encoded by the encoder unit 22 of the data processing unit 2. Moreover, the structure which the external output part 7 transmits an analog signal directly to the display Dp may be sufficient. Further, when the broadcast is analog, the additional information may be transmitted superimposed on the VBI, for example.

  In this embodiment, an optical disk device is used as the recording / playback device according to the present invention, but the present invention is not limited to this. As a recording / reproducing apparatus of the present invention, for example, a recording / reproducing apparatus having only a hard disk, a recording unit for recording recorded data in a semiconductor memory, etc., and a recording unit capable of recording the recording data are recorded and recorded. Can be widely adopted.

  Alternatively, the recorded title list display once performed may be recorded in the recording unit 4, and the recorded title list display may be called when the user requests the recorded title list display. At this time, when the recording data is changed, the recording title list display of the changed part can be changed.

The recorded data shown in FIG. 5 is represented as video data Pd, audio data Sd, and caption data Ld.

  Among TV programs, for example, there is a program (referred to as series recording data or series recording title) that broadcasts a long story divided into a plurality of episodes, such as a continuous drama. FIG. 5 schematically shows recorded data St1 of the first episode of the drama S, recorded data St2 of the second episode, recorded data St3 of the third episode, and recorded data St4 of the fourth episode.

  In a series of dramas being broadcast on television, the first part of each story is often overlapped with the end of the previous broadcast in order to help the user remember the contents of the previous broadcast. The recorded data recorded in the recording unit 4 of the optical disc apparatus A includes recorded data in which each story of the continuous drama S is recorded from the beginning to the end. As shown in FIG. The first part of the story recording data overlaps with the last part of the previous recording data.

  For example, in the case of the recording data of the continuous drama as shown in FIG. 5, the last portion Lst1 of the recording data St1 of the first episode overlaps with the first portion Opn2 of the recording data St2 of the second episode. The recording data St3 for the third episode and the recording data St4 for the fourth episode are the same.

  When recording title list display M1 and M2 is performed using such recording data, the caption of the head portion is displayed on the caption display portion Lt of the selected recording title. The caption of the last part (overlapping part) of the previous recorded title is displayed. Since the caption is a description of the scene of the previous recorded title, the scene associated with viewing the caption may be different from the scene actually included in the recorded title, which may cause confusion for the user.

  Therefore, the optical disc apparatus A according to the present embodiment performs a recorded title list display M3 as shown in FIG. The recorded title list display M3 shown in FIG. 6 is the same as the recorded title list display M1 shown in FIG. 2 except that it includes a moving image display unit Mv. The substantially same parts are denoted by the same reference numerals, and detailed description thereof is omitted. To do.

  As shown in FIG. 6, the recorded title list display M3 displays a list of the first to fourth episodes of the serial drama S. As shown in FIG. 5, in the serial drama S, the first part of the recording data of each story, excluding the first episode, overlaps with the last part of the recording data of the previous time. In the recorded title list display M3 shown in FIG. 6, the recorded title of the second episode of the serial drama S is selected, and the caption display portion Lt of the recorded title of the second episode overlaps with the last portion of the first episode. A certain number of characters are displayed starting from the portion immediately after the portion (see FIGS. 5 and 6).

  For example, in FIG. 5, the last part Lst1 of the caption data Ld of the recording data St1 of the first episode “OO”, and the first part Opn2 of the caption data Ld of the recording data St2 of the second episode "OO ◇ ..." matches. Therefore, as shown in FIG. 6, in the recorded title list display M3, the subtitle display portion Lt of the recorded title of the second episode has a portion “OOΔΔ...” Immediately after the first portion Opn2 as a subtitle. indicate. The displayed subtitles have a certain number of characters.

  In the recorded title list display M3, the recorded data St3 of the third episode and the recorded data St4 of the fourth episode are also displayed with the subtitles immediately after the first overlapping portion Opn3 and Opn4. Moreover, since the video data Pd, the audio data Sd, and the caption data Ld of the recording data each include time information, all the data can be synchronized. Therefore, in the recorded title list display M3, a still image of the video data Pd having the same time as the caption displayed on the title information display unit Ti is extracted as a thumbnail image and displayed on the thumbnail image display unit Tn.

  Furthermore, the recorded title selected by the user (in FIG. 6, the second episode, the cursor Cs is hit) is a portion where the thumbnail image display unit Tn displays the subtitle of the title information display unit Ti on the moving image display unit Mv. Is the subtitle display part Lt. Then, the subtitle display portion Lt scrolls and displays the subtitle of the portion immediately after the first portion Opn2 that overlaps the final portion Lst1 of the first story. Similarly, the moving image display unit Mv displays a moving image (video data) from a portion immediately after the first portion Opn2.

  The display procedure of such recorded data list display will be described with reference to a flowchart. FIG. 7 is a flowchart showing the operation of the optical disc apparatus when performing the list display shown in FIG.

  In the optical disc apparatus A, when receiving an instruction for recording title list display M4 from the user via the operation input unit 8 (step S21), the control unit 3 searches the designated folder of the recording unit 4 (step S22). . The control unit 3 determines whether there is any series recording data in the designated folder (step S23). When there is no series recording data (No in step S23), a display such as a recording title list display M1 or a recording title list display M2 is performed. Note that the operation in this case is the same as described above, and is therefore omitted.

  If there is series recording data in the folder (Yes in step S23), the control unit 3 confirms all the series recording data and confirms the recording date and time (step S24). The control unit 3 confirms the recording date and time, and extracts the first part of the caption and the thumbnail image of the part from the oldest recording data (step S25). The control unit 3 extracts the subtitles of each recording data and compares the subtitles of each recording data with the subtitles of the recording data of the recording data immediately before the recording date (step S26).

  This comparison of subtitles compares the first part of the subtitles extracted from the recording data with the last part of the subtitles extracted from the recording data of the previous recording date and time (see FIG. 5). When there is a common part in the caption data (in the case of Yes in step S26), the control unit 3 displays the caption immediately after the part that overlaps the recording data of the recording date and time immediately before the first recording data and the thumbnail of the part. An image is extracted (step S27). If there is no overlapping part (No in step S26), the caption of the first part of the recorded data and the thumbnail image of that part are extracted (step S28).

  The controller 3 confirms whether the currently confirmed recording data is the recording data of the latest recording date and time of the series recording data (step S29). In the case of the newest series (in the case of step S29), the control unit 3 sends the subtitles and thumbnail images used for the recording title list display M3 extracted from all the series recording data to the OSD generation unit 6 to generate the recording title list display M3. (Step S210). Further, the control unit 3 stores the time information of the start portion of the caption of each series recording data in the memory 5 (step S211).

  The control unit 3 detects information from the operation input unit 8 and detects a recorded title selected by the user (struck by the cursor Cs) (step S212). The control unit 3 accesses the memory 5 and extracts time (start time) information of the start portion of the caption of the selected recording title (step S213). The control unit 3 extracts video data and caption data of the recording data corresponding to the selected recording title from the recording unit 4 (step S214).

  In accordance with the instruction from the control unit 3, the OSD generation unit 6 synthesizes the subtitle display unit Lt (lower two levels of the title information display unit Ti) of the recorded title list display M3 so that subtitles are sequentially sent and displayed (step S215). ).

  The control unit 3 sends an instruction to the external output unit 7, superimposes the video data on the moving image display unit Mv of the recorded title list display M3, and sends it to the display Dp (step S216).

  As described above, in the optical disc apparatus A, the confusion of the user is suppressed by not displaying the subtitles, thumbnail images, and video data (moving image) of the overlapping part of the series recording data in the recording title list display M3. be able to. Thereby, it is possible to assist the selection of the recorded title including the user's desired scene.

  Here, since the series drama refers to the recording data of the continuous drama, the first part of the subtitle extracted from the recording data is compared with the end of the subtitle of the recording data of the previous recording date and time. However, it is not limited to this. For example, when the series recording data is recording data such as a news show or a variety show, the first part may match. When such series recording data is provided, the first part of the subtitles of all the series recording data may be compared. Furthermore, there is a case where it is not known whether the beginning is common or whether the first part of the recording data is superimposed on the last part of the recording data of the previous date and time. In this case, it takes time, but the entire subtitles may be compared.

  Further, when a recorded title is selected from the recorded title list display M3 and played back, the playback may be performed by omitting a portion overlapping with the recorded title of the recording date and time immediately before the selected recorded title. Further, in the above description, a portion where the subtitles included in the recorded data completely match is excluded, but a portion where a certain percentage (for example, 80%) matches may be excluded. The same may be done when comparing captions.

(Fourth embodiment)
Still another example of recording data list display of an optical disc apparatus which is an example of a recording / reproducing apparatus according to the present invention will be described with reference to the drawings. FIG. 8 is a diagram showing another example of a recorded title list display by the recording / playback apparatus according to the present invention. Note that the recording / playback apparatus of this embodiment has the same configuration as the optical disk apparatus shown in FIG. 1, and will be described with reference to the optical disk apparatus of FIG. The recorded title list display M4 shown in FIG. 8 also displays series recorded titles.

  There are cases where the series recording title is a combination of a plurality of small programs such as a news program. In the case of such series-recorded titles, although the contents of the small programs are different, the performers, the program structure, and the title names are almost the same. When such a list of series recording titles is displayed, the same overview is displayed, and the user cannot confirm the contents of the recording titles simply by looking at the overview.

  Therefore, when displaying a list of series recording titles including small programs having the same configuration as described above, a recording title list display M4 as shown in FIG. 8 is used. The recorded title list display M4 shown in FIG. 8 is the recorded title list display shown in FIG. 2 except that the lower two levels of the title information display portion Ti of all the recorded titles displayed in the list are subtitle display portions Lt. The same reference numerals are given to substantially the same parts, and detailed description of the same parts is omitted.

  That is, subtitles extracted from the additional data of the recorded data are displayed in the lower two levels of the title information display section Ti of each recorded title. In addition to the title of the small program, the subtitle displays the content of the small program as a character string. Therefore, the user can easily grasp the content of the recorded title by comparing the subtitles. That is, by using the recorded title list display M4, it becomes possible to assist the user in selecting the recorded title.

  In the recorded title list display M4, the lower two levels of the title information display portion Ti of all recorded titles are used as the caption display portion Lt, but the present invention is not limited to this. For example, a plurality of recording titles may be selected by the user, and the lower two levels of the title information display section Ti of the selected recording title may be used as the caption display section Lt.

  In the recorded title list display M4, the caption display section Lt of each recorded title is configured to display a specified number of subtitles. However, the present invention is not limited to this, and the caption display section Lt of each recorded title is scrolled. May be displayed. At this time, scrolling of subtitles is preferably synchronized.

  Further, when a recorded title is selected from the recorded title list display M3 and played back, the playback may be performed by omitting a portion overlapping with the recorded title of the recording date and time immediately before the selected recorded title.

(Fifth embodiment)
Still another example of recording data list display of an optical disc apparatus which is an example of a recording / reproducing apparatus according to the present invention will be described with reference to the drawings. FIG. 9 is a diagram showing another example of a recorded title list display by the recording / playback apparatus according to the present invention. Note that the recorded title list display M5 shown in FIG. 9 is the same as the recorded title list display M4 shown in FIG. 8 except that the display method of the caption display portion Lt is different, and substantially the same parts are denoted by the same reference numerals. Detailed description of the same part will be omitted. The recording / playback apparatus of the present embodiment has the same configuration as the optical disk apparatus shown in FIG. 1, and will be described with reference to the optical disk apparatus of FIG.

  Usually, subtitles are often included from the beginning to the end of the recorded title. Therefore, it takes time and effort for the user to check all the subtitles of the recorded title. Therefore, in the optical disc apparatus A according to the present embodiment, a subtitle including a character string input by the user is displayed.

  For example, in the recorded title list display M5 shown in FIG. 9, the lower two levels of the title information display portion Ti of each recorded title are set as the caption display portion Lt, and a character string Ch1 (here, “◯” determined in advance by the user). △ ◇ ○ □ ”) is included. In the recorded title list display M5, the character string Ch1 included in the caption is highlighted, but the present invention is not limited to this. For example, a display that makes it easy to visually recognize the character string Ch1, such as a bold character, an italic display, and an underline, can be widely used.

  In the recorded title list display M5 shown in FIG. 9, a part of the subtitle (phrase) including the predetermined character string Ch1 is displayed, but the present invention is not limited to this. For example, a sentence in which a predetermined character string Ch1 is the first may be displayed, or a sentence in which the last is a predetermined character string Ch1 may be displayed. In such a case, since the user can easily recognize the predetermined character string Ch1, it is not necessary to perform display that makes it particularly easy to visually recognize.

  A procedure for performing such a recorded title list display M5 will be described with reference to the drawings. FIG. 10 is a flowchart showing the procedure for displaying the recorded title list shown in FIG. The control unit 3 confirms the character string Ch1 (here, “◯ △ ◇ ○ □”) input via the operation input unit 8, and stores the character string Ch1 in the memory 5 (step S31). Although illustration is omitted, it is assumed that an operation input for performing the recorded title list display M5 has been performed before step S31.

  The control unit 3 accesses the storage unit 4 and extracts subtitle data from the recorded data included in the selected folder (step S32). The control unit 3 searches whether or not the predetermined character string Ch1 is included in the caption data (step S33).

  When the character string Ch1 is not included in the caption data (No in step S33), the control unit 3 extracts the caption of the first part of the recorded data (step S34). When the character string Ch1 is included in the caption data (Yes in step S33), the control unit 3 extracts a phrase including the predetermined character string Ch1 of the caption (step S35). Then, the control unit 3 sends the caption data extracted from each recording data to the OSD generation unit 6, and sends an instruction to generate an OSD image of the recorded title list display M5 to the OSD generation unit 6 (step S36).

  The control unit 3 sends the recording data to the external output unit 7 and sends the portion corresponding to the phrase including the predetermined character string Ch1 of the caption to the video display unit Mv with the video data superimposed on the display Dp. An instruction is sent to the external output unit 7 (step S216).

  In this way, it is possible to easily select recorded data including a scene desired by the user. In the present embodiment, the thumbnail image of the thumbnail image display unit Tn may be a still image extracted from the time including the subtitle character string Ch1 of the moving image data.

  In the present embodiment, a phrase including a predetermined character string Ch1 of a subtitle is displayed on the subtitle display unit Lt. However, the present invention is not limited to this. A clause that does not include the predetermined character string Ch1 may be displayed.

(Sixth embodiment)
In each of the above-described embodiments, in the optical disc apparatus which is an example of the recording / playback apparatus, the control unit 3 confirms the recording data (subtitle data) of the recording unit 4 when there is an instruction to display the recording title list. It has become. When the control unit 3 confirms the caption of the recorded data every time there is an instruction to display the recorded title list, it takes time to confirm. Therefore, in the optical disc apparatus according to the present embodiment, the internal character strings of the recording data included in the recording unit 4 are stored as a database.

  FIG. 11 is a diagram illustrating an example of a database of character strings included in subtitles. Note that the recording / playback apparatus of this embodiment has the same configuration as the optical disk apparatus shown in FIG. 1, and will be described with reference to the optical disk apparatus of FIG. FIG. 11 shows the caption database Db1 for title X. The caption database Db1 includes a time display unit Tm and a character string display unit Cp.

  The caption database Db1 shown in FIG. 11 displays character strings Ch2, Ch3, and Ch4 that are given in advance to the character string display unit Cp. In the time display portion Tm, the time that each of the character strings Ch2, Ch3, and Ch4 appears is displayed.

  When such a caption database Db1 is provided, the control unit 3 does not need to search all of the captions, can search for a character string in the captions in a short time, and displays a recorded title list. It is possible to shorten the time until.

  Note that the caption database Db1 may be searched for captions when the encoded data is recorded in the recording unit 4 to create the caption database Db1. Further, each time a predetermined character string is searched, the search character string and the time when the character string appears may be added to the database Db1.

  In the above-described embodiment, a character string input from the user is used as a character string for searching in the subtitles, but the present invention is not limited to this. For example, a character string frequently included in a title name, a performer, a subtitle, and the like is automatically extracted from the reproduction recording of the recorded data, and the character string and the time when the character string appears are added to the database Db1. Also good. Also, common portions (sentences, character strings) of subtitles of a plurality of recorded data may be extracted and added to the subtitle database.

(Seventh embodiment)
Still another example of recording data list display of an optical disc apparatus which is an example of a recording / reproducing apparatus according to the present invention will be described with reference to the drawings. FIG. 12 is a view showing another example of the recorded title list display by the optical disc apparatus which is an example of the recording / reproducing apparatus according to the present invention. Note that the recording / playback apparatus of this embodiment has the same configuration as the optical disk apparatus shown in FIG. 1, and will be described with reference to the optical disk apparatus of FIG. Further, the control unit 3 operates as a narrowing means.

  Most of the recorded data recorded so far is recorded in the recording unit 4 in most cases. When the user selects the recording data, the user selects the recording titles that meet a certain condition and selects from the narrowed recording title list display rather than selecting directly from the recording title list display in which all the recording titles are displayed. However, there are cases where it can be selected efficiently.

  When narrowing down recorded titles, first, the number of candidates is often reduced by classifying by category such as channel, recording date, title, genre, and the like. For this reason, in the recorded title list display M6 shown in FIG. 12, a title genre display portion Tj with a small amount of character information such as title and genre is displayed instead of the title information display portion Ti that displays detailed information of the recorded title list display M1.

  Further, in the recorded title list display M6, the title genre display section Tj has a smaller number of display characters to be displayed than the title information display section Ti, and can narrow the display area of one recorded title. Accordingly, the recorded title list display M6 can display more recorded titles than the recorded title list display that displays the title information display unit Ti.

  Then, the user determines the narrowing conditions while viewing the recorded title list display M6, and inputs the conditions via the operation unit 8. When the narrowing condition is input, the control unit 3 extracts the recording titles that match the narrowing condition from the recording titles displayed in the recording title list display M6. Display (refine search).

  For example, when the user inputs a narrowing condition of “titles recorded in a week from 2/1 to 2/7” from the operation unit, the control unit 3 extracts a recording title that matches the narrowing condition, The recorded title list display M1 is performed with the narrowed-down recorded titles. As described above, after narrowing down the recording titles, by performing the title information display Ti and the caption information Lt including a large number of character strings, the amount of character information to be confirmed by the user can be reduced, and the recording by the user Convenient title selection.

  In this embodiment, after narrowing down the recording titles, the recording title list display M1 shown in FIG. 2 is adopted as the recording title list display. However, the present invention is not limited to this. Depending on the recording titles after narrowing down, the recording title list display M2 shown in FIG. 4, the recording title list display M3 shown in FIG. 6, the recording title list display M4 shown in FIG. 8, and the recording title list display M5 shown in FIG. Display may be performed. The selection of the recorded title list display after narrowing down may be determined by the control unit 3 based on narrowing conditions or the like, or may be switched by the user.

  In addition, when there are a large number of narrowed recording titles in one narrowing search, the recorded title list display M6 including the title genre display portion Tj may be performed again. Only when the number of narrowed recording titles is equal to or less than a certain number, any one of the recording title list display M1 to the recording title list display M5 including the title information display portion Ti and the caption information Lt is displayed. May be.

  In the present embodiment, the recorded title list display M6 includes a thumbnail image display unit Tn, a channel display unit Cn, a recording date display unit Tm, and a title genre display unit Tj. However, the present invention is not limited to this, and a display showing the characteristics of the recorded title, for example, a thumbnail image display unit Tn and a title genre display unit Tj may be displayed. The contents to be displayed may be determined in advance or may be designated by the user. In addition, when narrowing down a plurality of times, information related to the narrowing conditions at the previous narrowing search may not be displayed.

  By displaying such a list of recorded titles, it can be used to search for recording data of a recording / playback device that employs a recording method that records all broadcasts (selected by the user) for a specified time. This saves you the trouble of searching for recorded data.

  As mentioned above, although embodiment of this invention was described, this invention is not limited to this content. The embodiments of the present invention can be variously modified without departing from the spirit of the invention.
