In response to the operation of the arbitrary setting key 325, the search target is switched, the search condition is cleared, the display order is switched, and the search is performed. The result can be switched (list / thumbnail).

  As described above, in this embodiment, the strip-shaped bars 511 and 512 are arranged on the upper and lower sides of the horizontally long display device 201 so as to sandwich the central field selection area 515, and the horizontal character arrangement guidance and the main operation keys are arranged. By arranging the (search target display 518), the visibility of the guidance and main operation keys arranged on the bars 511 and 512 can be improved, and the center field selection area 515 can be a horizontally wide area. . Then, the first selection key 514, the second selection key 514a, the third selection key 514b, and the lower hierarchy are sequentially arranged and displayed in the detailed development area 516 along the longitudinal direction of the wide field selection area 515. A plurality of selection keys for horizontally long character strings can be displayed on a single display screen in an easy-to-understand manner.

  Next, on the basis of FIG. 8 to FIG. 11, the second search step realizing means capable of searching a desired frame screen by text search from the content searched in the first search step via the second search DB 420. Will be described in detail. FIG. 8 is a functional block diagram for realizing the second search step. FIG. 9 is a data structure diagram of the indexing data. FIG. 10 shows the data structure of keyword data. FIG. 11 is a data structure diagram of the search result mark portion.

  First, an overview of various functions for realizing the second search step provided in the television receiver 1 according to this embodiment will be described with reference to FIG. Although all these functional blocks are described as software programs executed by the microcomputer 101, some or all of them may be realized as hardware.

  As shown in FIG. 8, main body 100 according to the present embodiment includes analysis moving image data input unit 121, indexing data generation unit 122, indexing data holding unit 123, indexing data input unit 124, and keyword data generation unit 125. , Keyword data holding unit 126, keyword data input unit 127, keyword input unit 128, keyword position data generation unit 129, keyword position data holding unit 130, keyword position data input unit 131, and keyword presentation unit 132. A keyword position presentation unit 133, a reproduction control unit 134, a reproduction moving image data input unit 135, an audio output unit 136, an image display unit 138, and a reproduction position designation unit 137.

  However, when indexing data is not generated by the main body 100, for example, when indexing data already created by another apparatus is used, the analysis moving image data input unit 121, the indexing data generation unit 122, and the indexing data holding unit 123 Not required. When keyword data is not generated by the main body 100, such as using keyword data that has already been created by another device, the keyword data generating unit 125 and the keyword data holding unit 126 are not essential. Further, when keyword position data is not generated by the main body 100, such as using keyword position data that has already been created by another device, the keyword position data generating unit 129 and the keyword position data holding unit 130 are not essential.

  In FIG. 8, the analysis moving image data input unit 121 inputs content information for generating indexing data to be described later from the program information extraction unit 103.

  The indexing data generation unit 122 is based on the spoken dialogue or displayed character string and the time when the dialogue or character string is spoken or displayed in the moving image data input in the analysis moving image data input unit 121. The contents information is indexed to generate indexing data shown in FIG. For example, the subtitle data of the spoken dialogue is acquired and recorded along with the character string and the time for which it is displayed, thereby creating the indexing data shown in FIG.

  In digital television broadcasting, a subtitle ES is sent in the same way as an audio ES (Elementary Stream) or video ES. By acquiring and decoding this subtitle ES, Information on the time at which it is displayed can be acquired, and the indexing data shown in FIG. 9 can be generated based on these information.

  Alternatively, the indexing data generation unit 122 may generate the indexing data shown in FIG. 9 by recognizing the voice of the moving image data input in the analysis moving image data input unit 121 and generating a character string thereof. As this voice recognition technique, a known technique can be used, and the description thereof is omitted here. The result of speech recognition need not be a character string but may be a phoneme feature. In this case, the phoneme feature may be stored in the character string storage area of the indexing data in FIG. If the result of speech recognition is other than a character string such as a phoneme, the keyword position data generation unit 129 may be configured to search for a keyword appearance position other than a character string such as a phoneme, as will be described later. . This will be described later in the description of the keyword position data generation unit 129.

  Alternatively, the indexing data generation unit 122 recognizes the telop displayed on the image of the moving image data input in the analysis moving image data input unit 121 and generates the character string to generate the indexing data shown in FIG. May be. As this telop recognition technique, a known technique can be used, and the description thereof is omitted here. The result of telop recognition need not be a character string, but may be a shape feature such as the number of sides of a character. In this case, the shape feature may be stored in the character string storage area of the indexing data in FIG. When the telop recognition result is other than the character string such as the shape feature, the keyword position data generation unit 129 is configured to search the keyword appearance position other than the character string such as the shape feature as described later. That's fine. This will be described later in the description of the keyword position data generation unit 129.

  Next, the data structure of the indexing data generated by the indexing data generation unit 122 will be described with reference to FIG. Reference numeral 601 is a dialogue to be spoken at a certain time or a displayed character string number, and reference numeral 604 is a speech to be spoken or a displayed character string. Here, in the case of subtitle information, the spoken dialogue can be a character string as a decoding result. Moreover, if it is a speech recognition result, it can be set as the character string of the recognition result obtained by speech recognition with respect to the sound per unit time, or can be made into phoneme data. In the case of a telop recognition result, it can be a character string of a recognition result obtained by telop recognition when it is recognized that a telop has appeared, or shape feature data such as the number of sides and the number of strokes.

  Reference numeral 602 denotes the data amount of data stored in 604 such as the number of bytes of the character string stored in the character string 604 and the amount of phoneme data, and can be particularly the number of bytes of the data. Reference numeral 603 denotes a time at which data stored in 604 is actually output, that is, a time at which data related to dialogue or characters stored in the character string 604 is read or displayed. For example, in the case of caption information, this can be the time of the decoding result. Further, if the speech recognition result is speech recognition for speech per unit time, the time when the speech is output can be set. In the case of telop recognition, the time when the telop is displayed when it is recognized that the telop has appeared can be set. The indexing data generation unit 122 configures an entry (610) with a set of data from the character string number 601 to the character string 604 described above. Here, FIG. 9 shows that there are particularly three entries 610 from 611 to 613.

  The indexing data generation unit 122 sets all data to 0 as indicated by the entry 314 when the entry 610 is eliminated. As a result, the indexing data input unit 124 described later can know the end of the entry when the indexing data is read.

  In FIG. 9, for example, the area size of the character string number 601 is 4 bytes, the area size of the data amount 602 is 4 bytes, the area size of the time 603 is 8 bytes, and the area size of the character string 604 is N bytes. However, the present invention is not limited to this, and it may be determined by securing an area where each data can be sufficiently stored for the moving image data.

  Returning to the description of FIG. 8, the indexing data holding unit 123 holds the indexing data generated by the indexing data generation unit 122. This can be realized, for example, by storing the indexing data generated by the indexing data generation unit 122 in the storage device 109 or the secondary storage device 110.

  The indexing data input unit 124 inputs the indexing data held in the indexing data holding unit 123 or the indexing data already generated by another device or the like. This can be realized, for example, by reading the indexing data stored in the storage device 109 or the secondary storage device 110. Alternatively, when indexing data that has already been generated by another device or the like is input, it can also be acquired by connecting to network data via the external interface unit 111.

  The keyword data generation unit 125 analyzes and parses the character string portion of the indexing data input by the indexing data input unit 124, and generates the keyword data shown in FIG. A dictionary 139 and / or a morphological analysis technique can be applied to the analysis of the character string portion and the generation of the keyword data. It should be noted that a known technique can be used for morphological analysis, and description thereof is omitted here.

  When analyzing the character string portion of the indexing data, the analysis accuracy can be improved by analyzing the character string of the space, the kana character, and the control code that specifies the character color and display position. This can be implemented by deleting the space character code from the caption data when indexing data is generated from the caption data. Also, deletion of a phonetic name can be performed by determining a character size control code and deleting a character string displayed in the size of the phonetic name.

  If the dictionary 139 uses, for example, a dictionary of names, a fixed keyword dictionary for each program or program category (collectively referred to as the type of video data) such as “weather forecast” and “home run”, a large number of keywords are extracted. It is possible to solve the problem that the list cannot be displayed and the user cannot find easily. This dictionary may be switched depending on the type of moving image data. The type of moving image data can be determined by, for example, metadata attached to a program, EPG data, user designation, or the like.

  In addition, if you use a keyword dictionary such as “Next”, “Next”, “Continue”, or a keyword dictionary used for introduction (topic breaks), picking this word will break the topic breaks in the video data. Can be expected to detect.

  The generated keyword can be presented by the keyword presentation unit 132.

  FIG. 10 shows an example of the data structure of the keyword data. Reference numeral 653 denotes a character string itself as a keyword, which is a character string portion of the indexing data analyzed and word-decomposed by the keyword data generation unit 125, and can be particularly a part of the character string portion of the indexing data. For example, as described above, a technique such as dictionary 139 and / or morphological analysis may be applied from the character string portion of the indexing data to extract a character string (keyword) corresponding to a noun word.

  Reference numeral 651 denotes a keyword number, and reference numeral 652 denotes a data amount (number of bytes) of a character string serving as a keyword. The keyword data generation unit 125 further takes statistics of keywords input from the user in the keyword input unit 128 described later, and may score according to the number of keywords specified by the user so far, for example, based on the statistics. good. In this case, in FIG. 10, the keyword data is assigned a score 654 to the keyword, and an entry 660 is formed with 651 to 654 as one set. FIG. 10 shows that there are three entries 661 to 663 as an example. The keyword data generation unit 125 may set all data to 0 as indicated by the entry 664 when there are no more entries. Thereby, the keyword data input unit 127 described later can know the end of the entry when the keyword data is read.

  In FIG. 10, for example, the area size of the keyword number 651 is 4 bytes, the area size of the number of bytes 402 is 4 bytes, the area size of the keyword character string 403 is N bytes, and the area size of the score 404 is 4 bytes. However, the determination is not limited to this, and it is only necessary to determine a sufficient area corresponding to each data range.

  Returning to the description of FIG. 8, the keyword data holding unit 126 holds the keyword data generated by the keyword data generating unit 125. This can be realized, for example, by storing the keyword data generated by the keyword data generation unit 125 in the storage device 109 or the secondary storage device 110.

  The keyword data input unit 127 inputs the keyword data held in the keyword data holding unit 126 or the keyword data already generated by another device. This can be realized, for example, by reading keyword data stored in the storage device 109 or the secondary storage device 110. Alternatively, when inputting keyword data that has already been generated by another device or the like, the corresponding keyword data is accessed through the external interface unit 111 to obtain the corresponding keyword data. That's fine. As this method, it is assumed that a known network data acquisition method is applicable, and detailed description thereof is omitted here.

  The keyword presenting unit 132 presents the keyword stored in the keyword data input by the keyword data input unit 127 to the user via the second search screen 550 as shown in FIG.

  Returning to the description of FIG. 8, the keyword input unit 128 inputs a keyword specified by the user. This can be determined, for example, by displaying the keyword selection window 590 on the second search screen 550 shown in FIG. 1 and selecting the keyword option 591 displayed in the keyword selection window 590. Note that when the user specifies a keyword in the keyword input unit 208, the moving image playback apparatus searches for and reproduces the position where the specified keyword appears in the moving image data. Thereby, the user can view a scene in which a desired keyword appears.

  The keyword position data generation unit 129 generates the keyword position data shown in FIG. 11 based on the keyword character string input by the keyword input unit 128 and the indexing data input by the indexing data input unit 124. This is because the keyword position data generation unit 129 is a part of the character string 604 of each entry 611 to 614 in the indexing data shown in FIG. 9 in which the keyword character string input by the keyword input unit 128 is input by the indexing data input unit 124. And the time 603 of the entry 610 in the indexing data where the character string of the input keyword is found is acquired and stored in the position 682 in the keyword position data shown in FIG.

  As described above, when the indexing data generation unit 122 stores other character strings such as phoneme features or shape features in the region of the character string 604 by speech recognition or telop recognition, the keyword position data generation unit 129 is converted into a phoneme feature or a shape feature based on the keyword character string input by the keyword input unit 128, searched from the character string 604 portion of each entry 610 in the indexing data, and the input keyword The time 603 of the entry in the indexing data that matches the phoneme feature or shape feature corresponding to the character string may be acquired and stored in the position 682 in the keyword position data shown in FIG.

  In FIG. 11, 681 is a position number. Reference numeral 682 denotes a position where the character string of the keyword input by the keyword input unit 128 appears in the moving image data when it is found. This position 682 may be the time when the character string in the moving image data is displayed. Here, the position in the moving image data is regarded as the time in the moving image data. That is, the time 603 of the entry in the indexing data when the character string of the keyword input by the keyword input unit 128 is found in the portion of the character string 604 in the indexing data input by the indexing data input unit 124 can be set. . Alternatively, the indexing data when the phoneme feature or the character shape feature corresponding to the keyword character string input by the keyword input unit 128 is found in the portion of the character string 604 in the indexing data input by the indexing data input unit 124. The entry time 603 in FIG.

  In FIG. 11, in particular, as an example, a character string of a keyword input by the keyword input unit 128, or a phoneme feature or a character shape feature is a character string 604 of three entries in the indexing data input by the indexing data input unit 124. It is shown that they are found in the portion, and these are stored in entries 691 to 693 in the keyword position data, respectively. The keyword position data generation unit 129 may set the last data of the entry 690 to 0 as indicated by the entry 694. Thus, the keyword position data input unit 131 (to be described later) can know the end of the entry 690 when the keyword position data is read.

  In FIG. 11, as an example, the area size of the position number 681 is 4 bytes and the area size of the position 682 is 8 bytes. However, this is not limited, and a sufficient area is secured corresponding to each data range. As long as it is determined.

  Returning to the description of FIG. 8, the keyword position data holding unit 130 holds the keyword position data generated by the keyword position data generation unit 129. This can be realized, for example, by storing the keyword position data generated by the keyword position data generation unit 129 in the storage device 109 or the secondary storage device 110.

  The keyword position data input unit 131 inputs the keyword position data held in the keyword position data holding unit 130 or the keyword position data already generated by another device or the like. This can be realized by reading keyword position data stored in the storage device 109 or the secondary storage device 110, for example. Alternatively, when inputting keyword position data already generated by another device or the like, the corresponding keyword position data is accessed via the external interface unit 111 by accessing the device in which the corresponding keyword position data is stored. Just get it. As this method, it is assumed that a known network data acquisition method is applicable, and detailed description thereof is omitted here.

  The keyword position presentation unit 133 presents the appearance position of the keyword designated by the user in the moving image data based on the keyword position data input by the keyword position data input unit 131. For example, as described with reference to FIG. 1, the time bar portion 571 is displayed below the second search screen 550 and corresponds to the entry position 682 in the keyword position data at a predetermined position of the time bar portion 571. This can be realized by adding a mark (search result mark portion 572) to the position.

  Returning to the description of FIG. 8, the reproduction moving image data input unit 135 inputs the reproduction target moving image data from the program information extraction unit 103. The image display unit 138 outputs the reproduction image generated by the reproduction control unit 134 described later to the monitor 200. The audio output unit 136 outputs the reproduction audio generated by the reproduction control unit 134 described later to the speaker 203.

  When the reproduction position is changed by the user, the reproduction position designating unit 137 notifies the reproduction control unit 134 (to be described later) to that effect. For example, when the right key 316 or the left key 317 of the cross key 310 is operated by the user, this can be realized by notifying the reproduction control unit 134 described later by an event or a flag.

  The reproduction control unit 134 inputs the moving image data through the reproduction moving image data input unit 135, generates a reproduction image and reproduction sound, and outputs them to the image display unit 138 and the audio output unit 217, thereby reproducing the moving image data.

  Next, an operation method of the second search step will be described with reference to FIGS. FIG. 12 is an operation flowchart of the second search step. 13 to 16 are screen transition diagrams of the second search screen.

  In FIG. 12, when the skip key 334 is operated during recording / playback of the content extracted in the first search step or the specific content (step 700), the microcomputer 101 displays a second search screen on the display device 201. 550 is displayed (step 702). Specifically, as shown in FIG. 13, the microcomputer 101 displays the recorded content on the entire display screen 201a during recording / playback. When the operation of the skip key 334 is performed, the microcomputer 101 displays the keyword selection unit 560 and the search result display bar at a position below the playback screen area 551 that is playing back the content recording as shown in FIG. For example, the part 570 appears so as to slide upward from below. Thus, in this embodiment, when the keyword selection unit 560 and the search result display bar unit 570 appear, the keyword selection unit 560 and the search result display bar unit 570 gradually appear at lower positions that are not easily noticeable. . In addition, since the keyword selection unit 560 and the search result display bar unit 570 that finally appear are displayed in a band-like shape and narrowly below the wide display screen 201a, the visibility of the content being played back may be hindered. Few.

  In the second search screen 550, the keyword selection unit 560 and the search result display bar unit 570 are each formed in a strip shape that is long in the left-right direction, and arranged side by side so that the longitudinal directions thereof coincide with each other. The keyword selection unit 560 and the search result display bar unit 570 can be efficiently arranged by efficiently utilizing the long side below the wide display screen 201a.

  The keyword selection unit 560 includes a horizontally-long rectangular selection window 561 that displays a currently selected keyword, and arrow marks 562 that are arranged adjacent to the top, bottom, left, and right. The arrangement of the arrow marks 562 facing the four directions of the selection window portion 561 makes the user associate the cross key 310 surrounding the enter key 311 of the remote controller 300 with the user, so that the operation of the keyword selection unit 560 is performed by the operation of the cross key 310. You can naturally recognize what is possible.

  The search result display bar 570 includes a band-shaped time bar 571 that is long in the left-right direction, a search result mark 572 that is set to divide the time bar 571 into left and right, and the length of the time bar 571. It includes a start time 573 and an end time 574 arranged at both ends of the direction, and a selection marker 575 indicating the selected search result mark portion 572.

  In this embodiment, the microcomputer 101 sets the playback time of the entire content to the length in the left-right direction of the time bar portion 571, the start time 573 arranged at the left end of the time bar portion 571 is set to time 0, and the time The playback time of the content is displayed at the end time 574 arranged at the right end of the bar portion 571. Then, a position on the time bar unit 571 corresponding to the time stored in the position 682 in the keyword position data is obtained from the length of the time bar unit 571 and the ratio of the reproduction time of the entire content data, and the keyword position data The search result mark portion 572 is assigned to the position on the time bar portion 571 corresponding to the time stored at the position 682 of the current position. The selection marker 575 is represented by an inverted triangle mark above the search result mark portion 572, and moves in the left-right direction by operating the right key 316 or the left key 317.

  On the other hand, in this embodiment, the operation guidance area 580 is provided by using the space below the search result display bar 570 so that the operation key operation guidance by the remote controller 300 on the second search screen 550 is indicated. Yes. For example, in this embodiment, the user can know that the blue key 325a of the arbitrary setting key 325 of the remote controller 300 and the cross key 310 can be operated by viewing the contents of the operation guidance area 580.

  In this embodiment, as an initial setting, when displaying the second search screen 550, the microcomputer 101 displays the first listed data of the keyword data on the selection window 561 and the time bar 571. The search result mark portion 572 corresponding to this keyword is displayed. The initial setting can be changed to an arbitrary keyword by calling a setting screen (not shown).

  Then, the microcomputer 101 monitors whether the up / down key of the cross key 310 has been operated (step 704), the left / right key has been operated (step 718), or the skip key 334 has been operated (step 726).

  Here, when the up / down key is operated, the microcomputer 101 displays the keyword selection window 590 in the reproduced image area 551 near the selection window 561 as shown in FIG. 15 (step 706). In the keyword selection window 590, keywords included in the keyword data are listed in the vertical direction. Then, the keyword previously displayed in the selection window 561 is highlighted, indicating that this keyword is in a selected state.

  In this state, when the left / right key is operated (step 730), the microcomputer 101 deletes the keyword selection window 590 and advances to step 720. When the up / down key is operated, the cursor is displayed in the keyword selection window 590. Is moved (step 710). When the determination key 311 is operated, the microcomputer 101 searches for the selected keyword, deletes the keyword selection window 590, and displays the selected and determined keyword on the selection window unit 561. (Step 714), the search result is displayed as a change of the search result mark portion 572 on the time bar portion 571 (step 716).

  On the other hand, when the left / right key is operated, the microcomputer 101 selects the selection marker 575 (up to the search result mark portion 572 in the direction in which the operation is instructed with reference to the position of the frame image reproduced in the reproduction image region portion 551. The cursor is moved (step 720). When the enter key 311 is operated (step 722), the frame image displayed in the reproduction image area portion 551 is changed to a frame image corresponding to the search result mark portion 572 selected by the selection marker 575. Here, the frame image of the reproduction image area 551 is switched by operating the enter key 311, but this step may be omitted and the frame image of the reproduction image area 551 may be switched by operating the left and right keys. .

  When the selection of a new keyword different from the keyword for which the keyword search result is displayed is received, the microcomputer 101 displays the new keyword in the selection window unit 561 and also displays a new keyword from the search data. A search is performed, and the display of the search result mark portion 572 is changed for the search result. At the same time, it is desirable to select and display a portion displayed in the earliest time zone in the search result mark portion. For example, the selection marker 575 is displayed on the search result mark portion 572 corresponding to the earliest time of the reproduced image. Note that the frame image of the reproduction image area 551 may be switched along with the movement of the selection marker, or the frame image of the reproduction image area 551 may be switched by operating the determination key 311. As a result, even when a moving image is being played back, a frame image in which the keyword is detected in the first time zone can be displayed without any special operation, and all searched frames can be displayed only with the right key of the cross key 310. The image can be confirmed. Therefore, the target frame image can be easily displayed with good operability.

  Alternatively, as shown in FIG. 16, the sub display screen 201b may be displayed on one side of the search result display bar unit 570, and the frame image before the operation of the enter key 311 may be displayed on the sub display screen 201b. . That is, in the example of FIG. 16, the keyword selection unit 560 and the sub display screen 201b are provided at the lower part of the display screen 201a so as to sandwich the search result display bar unit 570. Then, a frame image corresponding to the selection marker 575 of the time bar unit 571 is displayed on the display screen 201b. Then, based on the operation of the enter key 311, the frame image displayed on the display screen 201 b is displayed on the reproduction image area 551. According to this embodiment, while displaying the main frame image in the reproduction image area 551, the desired frame image is searched while being confirmed on the sub display screen 201b, and if necessary, the searched frame image is displayed. It can be displayed in the reproduction image area 551. Also, as shown in FIG. 16, by displaying the sub display screen 201b, the microcomputer 101 displays the length in the longitudinal direction of the search result display bar of the search result display bar unit 570 in a short manner. Along with this, the position of the search result mark portion 572 also changes according to the ratio of shortening. With this display, the sub display screen and the entire search result display bar can be displayed simultaneously without hiding a part of the search result display bar by displaying the sub display screen. Therefore, the visibility is improved, and it is possible to search with good operability while checking the frame image on the sub display screen 201b. Similar to the above description, on the sub display screen 201b, when changing the keyword, the microcomputer 101 may selectively display a portion displayed in the earliest time zone in the search result mark portion. Thereby, as described above, the target frame image can be easily displayed with good operability.

  Returning to FIG. 12, next, in this embodiment, when the microcomputer 101 operates the skip key 334 (step 726), the frame displayed in the reproduction image area 551 from the screen of the second search screen 550. The image is returned to the normal display screen as a full screen display (step 728).

  As described above, in this embodiment, the keyword selection unit 560 and the search result display bar unit 570 can be displayed in a band shape below the display screen 201a from the normal full screen display by operating the skip key 334. The keyword selection unit 560 is easily searched by operating the cross key 310, and the search result is visually displayed on the search result display bar unit 570, and further selected by the operation of the cross key 310. The frame image can be displayed on the display device 201.
