Description

  The present invention relates to a recorded program management apparatus that displays information of recorded program contents in a selectable state for a viewer in a recording device having a large-capacity storage device such as an HDD.

  2. Description of the Related Art In recent years, there has been provided a recording device that can store a large number of program contents by using a large-capacity HDD (hard disk drive) or the like, such as an HDD recorder. With such a recording device, server-type broadcasting in which received program content is once stored in the HDD and then played back is realized. In this server-type broadcast, program content and detailed additional information related thereto are stored in a large-capacity storage device such as an HDD, so that the stored program content can be viewed from a predesignated time, or additional information is stored. It is possible to search for scenes and view digests by using them.

  When a recorded program content is played back in such a recording device compatible with server-type broadcasting, a selection screen (so-called ECG (Electronic Content Guide: Electronic Content Guide) for allowing the viewer to select the program content to be played back is selected. )) Is displayed, and the viewer generally selects desired program content on this screen.

  Further, in this ECG, for example, program titles and the like are listed from the top in the newest order based on the recording date and time of the program content. At this time, the character set included in the program information is used to display the program title and contents of the program content. This character set includes kanji, alphanumeric characters, hiragana, katakana, and additional special characters whose operations are prescribed in advance by ARIB ((Radio Industry)).

  Here, the additional special characters are used for displaying in the same manner as the characters surrounded by a square frame in a radio / TV column such as a newspaper, and dozens or more characters are defined. For example, there are S (stereo broadcast) surrounded by a square frame, and two (bilingual broadcast) surrounded by a square frame.

  Further, the additional special characters are added to the program title, for example, and are defined and used as a part of a character set constituting the program title. In this specification, additional special characters are represented by [] (for example, [S] for stereo broadcasting).

Conventionally, in ECG, program content can be presented in a display form in which additional special characters are added to a program title. Further, a technique has been disclosed in which a guide for additional special characters is presented in ECG so that the viewer can easily understand the meaning of the additional special characters (for example, Patent Documents 1 to 3).

  By the way, with the recent increase in capacity of storage media, the number of program contents that can be stored in a recording device has become very large, for example, sometimes exceeding 500. In addition, when server type broadcasting becomes widespread, the transmission path through which program content is provided is not limited to broadcast radio waves such as conventional terrestrial digital broadcasting, BS broadcasting, CS broadcasting, etc., and Internet communication may be used. Therefore, the program content provided to the viewer is expected to increase further.

  In this way, when a large number of recorded program contents are displayed, if information related to program contents such as program titles is displayed in a list in order of recording date and time in the ECG, this list display should not fit on one screen, and several tens of pages Or nearly a hundred pages. As described above, in the conventional ECG, when a large number of program contents are stored in the recording device, searching for a desired program content itself is a complicated operation.

  On the other hand, the conventional ECG has a function such as a so-called keyword search that extracts program content including (or does not include) a predetermined keyword and displays a list of information related to the program content. For example, it does not have a function of rearranging information based on the first character of the program title) and displaying information related to the program content in a list. However, it is considered that the program title can be rearranged in the ECG by using the rearrangement technique by the data name used in the personal computer field.

  However, in ECG, the additional special characters added to the program title are only displayed as part of the program title, and are not subject to keyword search or rearrangement based on the program title. In other words, even if the additional special characters are useful for a specific viewer, the current situation is that they are not effectively used for searching for programs. That is, even if the viewer wants to watch a bilingual broadcast program, a sign language broadcast program, a subtitle broadcast program, etc., these programs cannot be efficiently searched.

  In addition, additional special characters are abbreviated and simplified display forms, so it may be difficult for viewers to understand their meaning at first glance. It cannot be said. In such a case, the viewer may feel annoyed with the additional special characters displayed in the ECG.

  An object of the present invention is to provide a recorded program management apparatus capable of efficiently searching for a desired program content even when a considerable number of program contents are stored in a recording device such as an HDD recorder.

In order to achieve the above object, the present invention is a recorded program management device comprising display control means for displaying a selection screen for program content to be output to a display device based on program information of the recorded program content, Display control means, program list generation means for generating a program list display screen (recorded program list) in which the title information of the recorded program content (which may include recording date and time) is displayed in a plurality of list frames; Program list rearranging means for rearranging title information on the program list display screen according to a predetermined condition, and additional special character information preliminarily defined as a character set of program information (for example, ARIB standard) is added to the title information (It does not matter where additional special character information is added, such as the beginning or middle of the title information). An additional special character detecting means for generating the program list display screen by adding the additional special character information to title information from the recorded program content, From the recorded program content, only the program content in which the additional special character information is added to the title information is extracted, and the additional special character information is added to the title information for the extracted program content, and the program list display screen Only the program content having specific additional special character information added to the title information is extracted, and the program information is displayed by adding the specific additional special character information to the title information for the extracted program content. It is possible to select and execute any one of generating screens, Instead means, based on the additional special character information added to the head of the title information (character code) or the title information, characterized in that it is a possible Sort title information in the program list display screen.

According to the present invention, in a recording device such as an HDD recorder, the program list generation means generates a program list display screen by adding additional special character information to the title information from the recorded program content, Only the program content in which the additional special character information is added to the title information is extracted from the program content , and the program information display screen is generated by adding the additional special character information to the title information for the extracted program content. In addition, only program content in which specific additional special character information is added to the title information is extracted, and the program information display screen is generated by adding specific additional special character information to the title information for the extracted program content. Can be selected and executed. Since the title information on the program list display screen can be rearranged based on the additional special character information added to the head of the information or the title information, the program search can be performed with the additional special characters on the program list display screen. Thus, the usability of the ECG is greatly improved, and additional special character information can be used effectively.

  This is particularly effective when the viewer searches for a program title to which a specific additional special character is added such as a bilingual broadcast program, a sign language broadcast program, or a subtitle broadcast program.

Thus, information SI1 indicating whether or not the program content has been viewed, recording date and time information SI2, and program title information SI3 are displayed.

  In the recorded program list display screen 40 of FIG. 4, the program contents are arranged in order of recording date and time, and the viewer operates the up and down buttons of the remote controller to move the selection of the list frames 43a to 43g up and down. The pages of the list frames 43a to 43g can be scrolled or paged. The selected list frame can be recognized by the viewer by changing the characters and the color in the frame or being displayed in reverse video (in FIG. 4, the selected state is shown in reverse video). In the conventional ECG, information regarding program contents is generally displayed in a list in the order of recording date and time.

  FIG. 5 is a display example of a recorded program list classified by program title name, and is an image diagram when an additional special character is added to the program title for display. For example, in the menu screen 30 of FIG. 3, when the viewer selects / determines the “display by program title name” selection button 33, the screen shifts to the recorded program list display screen 50 shown in FIG.

  In the recorded program list display screen 50 shown in FIG. 5, the configuration of the display frame and operation buttons is almost the same as that of the recorded program list display screen 40 shown in FIG. However, an operation button 54e for displaying only the program content in which the additional special character is added to the program title and an operation button 54g for switching whether to display the additional special character in the program title are activated. Is different.

  In FIG. 5, the program contents are rearranged and displayed in order of title name including the additional special character information. That is, the program information management control unit 16 and the menu display control unit 17 as display control means add the detected additional special character information to the title information when the additional special character information is added to the title information. A recorded program list is generated, and program contents in the recorded program list are rearranged based on the additional special character information.

  In the present embodiment, the title information on the program list display screen 50 is rearranged based on the additional special character information added to the head of the title information. That is, when an additional special character is added in the middle of the program title as in the program content 53a, the additional special character is not used for rearrangement.

  Specifically, for the program contents 53a to 53c, the character code of the first character is referred to, and for the program contents 53d to 53g, the character code of the first additional special character information is referred to, and these character codes are compared. Then, they are displayed in descending order.

  As described above, in the recorded program list display screen 50 of FIG. 5, the program contents are arranged in the order of program title names (with additional special characters), and the viewer operates the up and down buttons on the remote control to display the list frame 53a. The selection of .about.53g can be moved up and down, and the pages of the list frames 53a to 53g can be scrolled or paged. The selected list frame can be recognized by the viewer by changing the character and the color in the frame or being displayed in reverse video (in FIG. 5, the selected state is shown by reverse video).

  According to the recorded program list display screen 50 shown in FIG. 5, in the recorded program list, the program content is rearranged by the additional special character added to the program title, and the program content to which the same additional special character is added is displayed together. As a result, program search using additional special characters is facilitated, and the usability of the recorded program list is improved.

  In addition, even if the program title includes additional special character information, the program title is rearranged only by the first character, and the additional special character information added in the middle of the program title is not used as the target of rearrangement. It becomes easy to search for desired program contents on the list display screen 50.

FIG. 6 is a display example of a recorded program list by program title name, and is an image diagram when the program title is displayed without adding an additional special character. For example, in the program recording list 50 of FIG. 5, when the viewer selects / determines the selection button 54g for “switch special character presence / absence”, the screen shifts to the recorded program list display screen 60 shown in FIG.
In the recorded program list display screen 50 shown in FIG. 6, the configuration of the display frame and operation buttons is the same as that of the recorded program list display screen 50 shown in FIG.

  In FIG. 6, the additional special character information is not displayed, and the program contents are rearranged and displayed in a pure title order. That is, the program information management control unit 16 and the menu display control unit 17 as display control means use title information (character code) instead of additional special character information when additional special character information is added to title information. Based on this, the program contents in the recorded program list are rearranged. At this time, the additional special character information added to the title information is not displayed in the recorded program list.

  For example, a recorded program list when additional special character information is added to the program title and a recorded program list when additional special character information is not added to the program title are separately prepared in advance, as shown in FIGS. It is possible to easily switch the recorded program list.

  In the recorded program list display screen 60 of FIG. 6, the program contents are arranged in the order of program title names (no additional special characters), and the viewer selects the list frames 53a to 53g by operating the up and down buttons on the remote control. Can be moved up and down, and the pages of the list frames 53a to 53g can be scrolled or paged. Note that the selected list frame can be recognized by the viewer by changing the characters and the color in the frame or being displayed in reverse video (in FIG. 6, the selected state is shown in reverse video).

  As described above, according to the recorded program list display screen shown in FIG. 6, rearrangement based on pure title information is possible, so that it is possible to cope with the case where the viewer does not need to display additional special characters. Further, since the additional special character information itself is not displayed in the recorded program list, it is possible to avoid the viewer from feeling bothered about the display of the additional special character and to increase the number of characters that can be displayed as the title information.

  FIG. 7 is a display example of a recorded program list by program title name, and is an image diagram when only program content in which additional special characters are added to the program title is displayed. For example, in the program recording list 50 of FIG. 5, when the viewer selects / determines the selection button 54e of “only special characters”, the screen shifts to the recorded program list display screen 70 shown in FIG.

  In the recorded program list display screen 70 shown in FIG. 7, the configuration of the display frame and operation buttons is almost the same as that of the recorded program list display screen 50 shown in FIG. However, the difference is that the display of the operation button 74e (corresponding to the operation button 54e in FIG. 5) is “standard”. That is, when the operation button 74e is selected / determined in the recorded program list shown in FIG. 7, the screen shifts to the recorded program list display screen 50 shown in FIG.

  In FIG. 7, only the information of the program content to which the additional special character information is added as the program title is displayed in the order of the program title. As compared with FIG. 5, it can be seen that the program contents 53b and 53c in which the additional special character information is not added to the program title are not displayed in FIG.

  That is, the program information management control unit 16 and the menu display control unit 17 as display control means extract only the program content in which the additional special character information is added to the title information, and the title information and additional special information of the program content are extracted. Character information is displayed in the recorded program list.

  In the recorded program list display screen 70 of FIG. 7, the program contents are arranged in the order of program title names (only additional special characters), and the viewer selects the list frames 53a to 53g by operating the up and down buttons on the remote controller. Can be moved up and down, and the pages of the list frames 53a to 53g can be scrolled or paged. Note that the selected list frame can be recognized by the viewer by changing the characters and the color in the frame or being displayed in reverse video (in FIG. 7, the selected state is shown in reverse video).

  As described above, according to the recorded program list display screen shown in FIG. 7, only the program content in which the additional special character information is added to the title information is extracted, so that the program content desired by the viewer is determined. Etc. (for example, a bilingual broadcast program, a sign language broadcast program, a subtitle broadcast program) can be searched efficiently.

  The present invention is not limited to the above-described embodiment, and various modifications can be made. For example, in the above-described embodiment, a predetermined selection button is selected and determined from the menu screen 30 to shift to each recorded program list display screen. You may make it transfer to a list display screen. The operation for outputting the recorded program list display screen (FIGS. 4 to 7) may be any operation.

  Further, as shown in FIG. 7, not only all program contents with additional special character information added to title information are extracted and displayed, but also only program contents with specific additional special character information added are displayed. You may make it extract and display.

  In addition, the transmission path through which program content is provided is not limited to broadcast radio waves such as terrestrial digital broadcast, BS broadcast, and CS broadcast, and Internet communication may be used.

  In addition, the specific configuration shown in the embodiment, such as the type of storage medium in which the recorded program is stored, the medium for recording the program information to be managed, and the recording method can be changed as appropriate without departing from the spirit of the invention. is there.
