Description

  The present invention relates to a recording / reproducing apparatus for displaying program titles of a plurality of recorded program data recorded on a screen and a screen display method thereof.

  In recent years, information storage devices such as hard disks have increased in storage capacity. Therefore, many recording programs can be recorded in the recording / reproducing apparatus including these information recording apparatuses.

  In such a recording / reproducing apparatus, recorded program data, a program title, and a program title are recorded in association with each other. Therefore, in the case of recorded program data such as a series drama, the program title names of the recorded program data are almost duplicated because the series names are the same.

In Patent Document 1, in order to display more information in a display area with respect to a limited display screen, a program that is displayed immediately before the title name of each program program displayed on the display screen is disclosed. Compared with the character string of the title name of the program, if there is the same part of a certain length at the beginning of the character string, it is determined that both program programs are related, and the title name of the subsequent program program Among these, the configuration is described in which the same character string portion is omitted.
JP 2007-104366 A

  However, in the recording / reproducing apparatus of Patent Document 1, the title name of each program program displayed on the display screen is compared with the character string of the title name of the program program displayed immediately before. Therefore, all the title names of the program programs serving as the reference displayed at the top of the display screen are displayed. Therefore, the latter part of the title name that does not enter the display column is omitted. In the case of a title name that contains the number of stories and title after a long title such as a drama, when the user sees the title of the program program that is the reference displayed on the top row of the display screen, the title Has the inconvenience that cannot be distinguished at a glance.

  An object of the present invention is to provide a recording / reproducing apparatus and a recording / reproducing method capable of displaying information necessary for a user to select a title of a recorded program.

  According to an embodiment of the present invention, there is provided a recording / reproducing apparatus for recording a plurality of program titles, an input unit for instructing display of the plurality of program titles recorded in the recording unit, and the plurality of programs When there is an instruction to display a title, a character string analyzing unit that analyzes a position where each character string of the plurality of program titles is separated, and a character string of the plurality of program titles analyzed by the character string analyzing unit Character string comparison means for comparing each of the plurality of program titles with a first part common to each of the plurality of program titles and a second part other than the first part, and a display position of the first part in the plurality of program titles Based on the display position designating means for designating the display position of the second part, the display position of the first part designated by the display position designating means and the display position of the second part It has a screen creation means for creating a list display screen, and display means for displaying the list display screen created by the screen creation means.

  By comparing the character strings of the title names of the recorded programs, the same character string and different character string portions can be detected separately. Therefore, the same character string portion is displayed in one place at a different position. Since the user is provided with the title name excluding the same character string as determination information for selecting a title, usability is improved.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram showing an overall configuration of a recording / reproducing apparatus 10 to which the present invention is applied. The recording / reproducing apparatus 10 has two types of disk drive units. The optical disc 101 is an information recording medium that can construct a video file. The disk drive unit 102 rotates and drives the optical disk 101 to read / write information. The hard disk drive unit 103 drives and records a hard disk. The disk drive unit 102 includes a rotation control system, a laser drive system, an optical system, and the like for the optical disk 101.

  The recording signal processing unit 104 can supply recording data to the disk drive unit 102 and the hard disk drive unit 104, and can receive a reproduced signal.

  The recording signal processing unit 104 handles recording or reproduction unit data, and includes an encoder unit, a decoder unit, a buffer circuit, a modulation / demodulation circuit, an error correction unit, and the like. The video signal and the audio signal are input from the tuner unit 106 to the recording signal processing unit 104. Then, the recording signal processing unit 104 displays an image on the image display device 30 connected to the recording / reproducing device 10.

  The control unit 105 includes an MPU (micro processing unit) or CPU (central processing unit), a ROM in which a control program and the like are written, and a RAM for providing a work area necessary for program execution. .

  The control unit 105 executes processing using the RAM as a work area according to the control program stored in the ROM. The non-volatile memory 107 stores various setting information, control information, and the like. When the control unit 105 receives operation information from the input unit 108 or receives operation information sent from the remote controller 20 via the light receiving unit 109, the operation content is reflected on the apparatus. Each part is controlled individually.

  The control unit 105 includes a title name character string analysis unit 105a, a character string comparison detection unit 105b, a detection character string display determination unit 105c, a detection character string display position designation unit 105d, and a title list screen creation unit 105e.

  The title name character string analysis unit 105a acquires information on the title name from the series descriptor information of each recorded program. The character string comparison / detection unit 105b compares overlapping portions of the character strings of the program titles. The detection display string display determination unit 105c determines a display character string based on the setting of the program title list omission function. The detected character string display position designation unit 105d separates the same character string portion and the non-identical character string portion to be displayed from each program title, and designates the display position on the screen. Based on the display position information, the title list screen creation unit 105e creates a display screen in accordance with the setting of the program title excluding the overlapping portion and the overlapping portion on the video display device.

  The title name abbreviation display according to the embodiment of the present invention will be described below. FIG. 2 is a diagram showing a plurality of recorded programs recorded on the optical disc 101 or the hard disk drive unit 103 that can be reproduced by the recording / reproducing apparatus 10 and program titles associated with these programs.

  For example, one program title among the recorded programs recorded in the hard disk drive unit 103 is [◯] [×] [Δ] ABCDEF GHIJK (88) “abcdefghi”. For example, [○] indicates that the recorded program is an audio commentary, [×] indicates that the recorded program is a subtitle broadcast, and [△] indicates that the recorded program is a digital broadcast. It is a symbol. “ABCDEF GHIJK” after that shows the series name of the program, (88) shows the number of stories, and “abcdefghi” shows the title (subtitle).

  FIG. 3 is a screen diagram in which the program title of the recorded program shown in FIG. 2 is displayed on the video display device. When the user inputs the display of the program title of the recorded program through the remote controller 20 or the input unit 108, the control unit 105 displays the program title of the recorded program recorded in the hard disk drive unit 103 as shown in FIG. A display screen is displayed.

  Here, it is assumed that eight recorded programs are recorded in a specific folder as shown in FIG. The video display device 30 displays program titles in two columns. Here, since it is a recorded program of a series program, each program title is overlapped with [○] [×] [△] ABCDEF GHIJK, and the number of subsequent stories and titles are different. In the video display device 30, program title names that do not fit in the display column for each program title on the program title list display screen are displayed with the latter part omitted. Here, since each program title is long and the preceding part of each program title overlaps, the video display apparatus displays only the overlapping preceding part for eight different program titles. In other words, a different post stage is not displayed for each program title. Therefore, it is difficult for the user to determine a desired recorded program on the display screen shown in FIG.

  In this case, the listability of titles is impaired on the program title list display screen of recorded programs. The user needs to refer to the detailed information displayed by selecting the display column of each program title with the remote controller 20. Therefore, especially when a series program such as a series drama is recorded every week, the first part of the program title overlaps. Since the display parts displayed in the display column of each recorded program displayed on the program title list display screen are exactly the same, the listability may be significantly impaired.

  Here, on the setting screen of the program title list omission function shown in FIG. 4, the user can make a setting for omitting the overlapping portions of the program titles on the program title list display screen as described above. Settings are made as follows.

  When the user makes a predetermined input using the remote controller 20, the control unit 105 displays the setting screen for the program title list omission function shown in FIG. 4 on the video display device 30. On the setting screen for the program title list omission function, select whether to omit the initial setting of each folder and the method of displaying the overlapped part, either one place display, omit the mark, one place display, or not display It is a screen.

  The user determines whether or not to omit the display of the program title list display screen shown in FIG. 3 before displaying the program title list display screen in which the program title, which will be described in detail later, is omitted as an initial setting item of each folder. You can choose.

  In addition, when the user displays the omitted part at a predetermined place on the screen in the item of the display method of the overlapping part, the user displays “one place display” and the predetermined part on the screen excluding the mark in the omitted part. "Display by omitting the mark" and "Do not display" can be selected when the omitted part is not displayed on the screen. Here, the mark is a symbol [○] [×] [△] that means the attribute of the program described above.

  Next, display of a program title list display screen in which program titles are omitted will be described with reference to the flowchart shown in FIG. here. When the user selects and decides “Do not omit” for the initial setting of each folder and “Display with one place without marks” for the display method of overlapping parts on the setting screen of the program title list omission function shown in FIG. The control unit 105 records the setting in the RAM based on the input of determination.

  First, the user selects display on the video display device 30 of a program title list display screen of a recorded program recorded in an arbitrary folder. The control unit 105 determines whether or not the program title list omission function is set (step S100).

  If the program title list omission function is not set (step S100, NO), the title list screen creation unit 105 does not omit each program title for the recorded program recorded in the selected arbitrary folder. A display screen is created and displayed on the video display device 30 (step S101).

  If the program title list omission function is set (YES in step S102), the control unit 105 enables the program title list omission function. Then, the title name character string analysis unit 105a compares the program title names in the folders (step S102). The title names are compared as follows. Here, FIG. 8 is a diagram showing a data structure of the series descriptor information of the recorded program.

  The title name character string analysis unit 105a also acquires series name information, story count information, title information, and character string delimiter position information specified from these information from the series descriptor information of each recorded program, and records them in the RAM. . Further, the title name character string analysis unit 105a also records, in the RAM, symbols indicating attributes of recorded programs such as audio commentary, subtitles, digital broadcasting, and stereo broadcasting specified by the additional symbol information.

  Next, the character string comparison / detection unit 105b compares overlapping portions of the character strings of the program titles acquired by the title name character string analysis unit 105a. At this time, the presence / absence of an overlapping portion is determined based on the separation position information interval of the character string acquired by the title name character string analysis unit 105a.

  For example, in the case of a program title “[O] [×] [Δ] ABCDEF GHIJK (88)“ abcdefghi ”shown in FIG. The front and rear are recognized as delimiter positions. Further, the character string comparison detection unit 105b recognizes the position before and after (88) and the position before and after “abcdefghi” as the break positions. That is, the title name character string analysis unit 105a, such as the series name and the number of stories, is divided in units of information acquired from the series descriptor information.

  For this reason, the character string comparison / detection unit 105b does not regard the character strings sandwiched between the delimiter positions as duplicates even if the character strings are partially the same. That is, the character string comparison / detection unit 105b regards a duplicate character string as long as it is duplicated in the division position unit from the division position to the division position.

  Further, when the title name has a plurality of delimiter positions, when the character string comparison detection unit 105b determines that the character string sandwiched between the delimiter positions in the middle is a non-identical character string, the delimiter position is thereafter Even if it is determined that the character strings sandwiched between are duplicated in the same character string, it is determined that the portion is not omitted. By detecting the duplicate character string by the character string comparison / detection unit 105b, at least one of the series name, the number of stories, and the title is displayed without being omitted. Therefore, the visibility of the program title list display screen in which the program title is omitted is improved.

  The character string comparison / detection unit 105b compares the character strings of the program titles in the folder using the character string delimiter position information. Then, the character string comparison / detection unit 105b detects the same character string portion and the non-identical character string portion. When the character string comparison / detection unit 105b does not detect the same character string portion that overlaps (step S103, NO), the control unit 105 selects each program title for the recorded program recorded in the selected arbitrary folder. A program title list display screen that is not omitted is displayed on the video display device (step S101). The character string comparison / detection unit 105b uses the program title of any one (for example, the recorded program with the oldest recording date / time recorded in the folder) as a reference for other program titles. The same character string part and non-identical character string part are detected.

  When the character string comparison / detection unit 105b detects the same character string portion that overlaps (step S103, YES), the detected character string display determination unit 105c determines a display character string based on the setting of the program title list omission function.

  Then, the detected character string display position specifying unit 105d separates the same character string portion and the non-identical character string portion to be displayed from each program title, and specifies the display position on the screen. FIG. 9 shows a display position information table at this time. The detected character string display position designation unit 105d designates the display position of each item on the screen based on the setting on the setting screen of the program title list omission function shown in FIG.

  Marks included in the title name at the top in FIG. 2 are [◯] [×] [Δ], and the eight title names from the top shown in FIG. 9 are common. The order of the title names is, for example, the date order recorded from above. Since it is set that the overlapping part is displayed with one mark omitted, the detected character string display position designating unit 105d displays a mark display field for each program title name in the display position information table as shown in FIG. X indicating that is not displayed.

  Further, “ABCDEF GHIJK”, which is the series name of the title name in the uppermost row shown in FIG. 2, is common to the eight title names from the top shown in FIG. Since it is set to display one place without overlapping parts, the detected character string display position designating unit 105d displays the series name display column for each program title name in the display position information table as shown in FIG. Set ○ to indicate that is displayed. Further, since the series name is a duplicate character string, the detected character string display position specifying unit 105d is displayed at one position at a predetermined position. Therefore, the same display position is set for the display positions of the series names among the eight title names.

  Also, the number of stories of the title name at the top in FIG. 2 (88) is not common to any of the eight title names from the top shown in FIG. And as a display method of an overlapping part, a mark is omitted and one place display is set. Therefore, as shown in FIG. 9, the detected character string display position designating part 105d is set in the display position information table, and in the talk number display column of each program title name, “◯” indicating display is set. The detected character string display position designating unit 105d is set so that the number of stories of eight title names is displayed at different predetermined positions because the number of stories is not a duplicate character string.

  Further, “abcdefghi”, which is the title of the title name in the uppermost row shown in FIG. 2, is common to four of the eight title names from the top shown in FIG. However, since the number of stories in the middle of the title name is not a duplicate character string, the subsequent title “abcdefghi” is also displayed regardless of whether it is a duplicate character string. And as a display method of an overlapping part, a mark is omitted and one place display is set. Therefore, the detected character string display position specifying unit 105d sets “◯” indicating display in the title display column of each program title name in the display position information table as shown in FIG. In addition, the detected character string display position designation unit 105d does not display the title in abbreviated manner, so that it is displayed at one position at a predetermined position. Therefore, the display position of the series name of the eight title names is set to the same display position as the display position set by the number of stories.

  When there is no identical character string portion for each program title, the detected character string display position specifying unit 105d specifies only the display position for each program title.

  Based on the display position information table, the title list screen creation unit 105e displays the series name that is an overlapping part on the video display device 30 at a predetermined display position (step S104), and the series that is the overlapping part from each program title. The number of stories excluding the name and the title are displayed at predetermined positions (step S105).

  Here, the initial setting items are set not to be omitted on the setting screen of the program title list omission function shown in FIG. Therefore, as shown in FIG. 6, the title list screen creating unit 105e does not display the program title shown in FIG. 3 in an abbreviated manner before displaying it on the video display device 30 based on the display position information table shown. Display the program title list display screen. Then, the title list screen creation unit 105e also displays a selection screen that can be switched by the user's operation to enable / disable the overlapping part omission function based on the display position information table shown in FIG.

  When the user selects the overlapping part omission function on the screen shown in FIG. 6, the title list screen creation unit 105e displays the overlapping part of each program title based on the display position information table of FIG. 9 as shown in FIG. To display. Then, the title list screen creation unit 105e displays the screen with the overlapping portions omitted for each program title.

  Therefore, the mark indicating the overlapping attribute information based on the set program title list omission function is not displayed, and the series name which is the overlapping portion is displayed in one place. Since only the number of stories and the title are displayed at a predetermined display position of each program title, the user can select a desired recorded program at a glance.

  Here, the program title is separated into a common part and a non-common part, and all of the common parts are displayed in one place, but the first to N characters of the common part are displayed in one place, and each program title is displayed. As for, the remaining part separated up to the Nth character may be displayed.

  In the display position information table shown in FIG. 9 described above, the case where a recorded program having the same series name is recorded in a specific file provided in the hard disk drive unit 103 has been described. As another example, the same applies to the case where a plurality of programs having different series names are recorded in a specific file. That is, the display position information table shown in FIG. 10 is created.

  When the character string comparison / detection unit 105b detects a program title having a series name different from the series name of the reference program title, the character string comparison / detection unit 105b determines that the character string comparison / detection unit 105b does not omit it. However, when a plurality of program titles having different series names are detected in the same file, the character string comparison / detection unit 105b uses a specific program title among the program titles determined not to be omitted as a reference, It is determined that common character strings such as are omitted. In this case, it is difficult to see a screen in which a plurality of series names are displayed together in one place on the abbreviated display screen. Therefore, the detected character string display position designating unit 105d sets the display position as shown in FIG. 10 so that the display screen is different for each series name to be omitted.

  In FIG. 10, the program title with the series name ABCDEF GHIJK has the display position set as 1-AA, but the program title with the series name ABCDEF LMN has the same display position as 2-AA. Does not display on the display screen. By scrolling the screen with the cross key of the remote controller 17, the user becomes a display screen of the program title that realizes abbreviated display for each series name. The display positions 1-AA and 2-AA of the series name mean that one place is displayed at a predetermined position on each different display screen.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. Further, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, you may combine suitably the component covering different embodiment.
