  An object of the present invention is to provide a data display device capable of displaying data while improving the convenience of information acquisition.

  FIG. 1 is a diagram illustrating a configuration example of a content display device that displays data acquired by broadcasting or communication. The content display device 100 is, for example, a mobile phone or personal computer equipped with a broadcast reception function, a television set or a hard disk recorder equipped with a communication function. The content display device 100 receives data such as video information and program information (Electronic Program Guide) such as news, dramas, and sports distributed from a broadcast or the Internet, and displays the received data.

  The communication unit 101 transmits news information, mail information, information organized by RSS (RDF Site Summary), web log (blog) information having a bulletin board writing and diary function, EPG (program information) via the Internet 102. ) And other types of data. Hereinafter, the received data is referred to as net content. This net content is stored in the net content storage unit 104 of the content storage unit 103. The communication unit 101 may be a wireless communication unit or a wired communication unit.

  The broadcast receiving unit 105 receives video information such as news, sports, and dramas, and data such as EPG from the broadcasting station 106 by digital broadcasting or analog broadcasting. Hereinafter, this data is referred to as broadcast content. The broadcast content is stored in the broadcast content storage unit 107 of the content storage unit 103. The content is not limited to being directly received from the broadcast station 106, and may be received via an artificial satellite, for example. The broadcast receiving unit 105 is not limited to receiving content wirelessly, but may receive content from a cable television station through a cable connection such as an optical fiber.

  The chapter extraction unit 108 extracts a chapter that is a scene change of the net content or broadcast content stored in the content storage unit 103. For example, the chapter is determined to be a chapter when the luminance of the video included in the content changes by more than a predetermined value, when the volume of the audio changes greatly, or when there is no audio. In addition, for example, in the case of news information, since it is often switched to a scene where a news caster is displayed for each news, or a telop or sound effect is inserted, such a predetermined video or telop is extracted. In some cases, it may be determined that it is a chapter. Further, the chapter extraction unit 108 may extract a plurality of chapters such as “large chapter” and “small chapter” by providing a plurality of levels of video and audio change thresholds.

  The chapter information indicating the position of the chapter extracted by the chapter extraction unit 108 is input to the content storage unit 103 and stored in association with the net content or the broadcast content.

  In this example, the chapter extraction unit is provided in the content storage unit 103, but may be provided in the content storage unit 103. In this example, the chapter extraction unit 108 extracts chapters from the content input from the content storage unit. However, the present invention is not limited to this, and the content is input from the communication unit 101 or the broadcast reception unit 105 to the chapter extraction unit 108. You may do it.

  The display control unit 110 reads the content stored in the content storage unit 104 in accordance with a user instruction input from the user interface unit 112 and outputs the content to the display unit 111. Details of the display control unit 110 will be described later.

  In FIG. 1, news information or the like shown as content stored in the net content storage unit 104 and the broadcast content storage unit is an example, and the present invention is not limited to this. The content is, for example, MPEG format (MPEG-2, MPEG-4, MPEG-7), H.264, or the like. H.264, TS (Transport Stream), PS (Program Stream), ES (Elementary Stream), and the like.

  FIG. 2 is a diagram illustrating an internal configuration of the display control unit 110 of the content display device 100.

  The character extraction processing unit 200 extracts character information included in the broadcast content stored in the broadcast content storage unit 107.

  FIG. 3 shows an example in which broadcast content such as news information is displayed on the display unit 111. For example, in the case of news information, the news content may be displayed as a telop 301 as shown in FIG. The character extraction processing unit 200 extracts the telop information embedded in these videos by video recognition. Moreover, not only video recognition but also text information may be extracted from voice information such as voice spoken by a news caster using voice recognition. In addition, when the content is text information, when using text information from EPG, or when text information is added to video information or audio information, without performing video recognition or voice recognition, Since this character information only needs to be extracted, the processing load of the character extraction processing unit 200 can be reduced. Character information is subjected to morphological analysis, and particles and articles are omitted, and characteristic keywords are extracted.

  The broadcast keyword storage unit 201 uses the character information extracted by the character extraction processing unit 200 as a keyword, and stores table information indicating the correspondence between the keyword and the broadcast content stored in the broadcast content storage unit 107. This makes it possible to search for broadcast content from the keyword.

  FIG. 4 is a diagram illustrating an example of broadcast table information stored in the broadcast keyword storage unit 201. The broadcast table information includes a content ID for identifying the content, chapter information indicating the positions of the large chapter and the small chapter, and date / time information indicating the date and time when the content corresponding to the chapter position is received by the communication unit 101 or the broadcast receiving unit 105. , A keyword extracted by the character extraction processing unit 200, viewing history information indicating a percentage (%) of the content reproduction, and the like.

  The broadcast table information is displayed on the display unit 111 via the display calculation processing unit 202 in response to a user input from the user interface unit 112. At this time, the order of information to be displayed may be changed according to viewing history information. For example, content that has not been viewed by the user is displayed at the top. From the displayed table information, the user uses the user interface unit 112 to select content to be reproduced.

  In this example, the case of dividing into large chapters and small chapters is shown. However, the present invention is not limited to this. One type of chapter information or three or more types of chapter information may be used. Also good. Further, the keyword information or the like may not be stored for each chapter, but the information may be stored for each content. However, by storing keyword information for each chapter, it is possible to make it easier for the user to find an interesting scene in one content.

  The character extraction processing unit 204 extracts character information included in the net content stored in the net content storage unit 104. Character information is subjected to morphological analysis, and particles and articles are omitted and characteristic keywords are extracted. The net keyword storage unit 203 stores the character information extracted by the character extraction processing unit 204 as a keyword. In addition, the net keyword storage unit 203 stores table information indicating the correspondence between this keyword and the net content stored in the net content storage unit 104. In this table information, whether the net content corresponding to the keyword is mail information or blog information, genre information indicating the type of the net content such as news information, and the acquisition date and time when the keyword is acquired by the character extraction processing unit 204 are displayed. The date and time information shown is included.

  FIG. 5 is a diagram illustrating an example of net table information stored in the net keyword storage unit 203. The net table information includes a content ID for identifying content, genre information indicating the type of content such as news and EPG, a keyword extracted by the character extraction processing unit 204, information indicating the date and time when the keyword was acquired, Evaluation value information indicating the topicality of the keyword, viewing history information indicating the percentage (%) of reproducing the content, and the like are included.

  Similarly to the broadcast table information, the net table information is displayed on the display unit 111 via the display calculation processing unit 202 by a user input from the user interface unit 112. At this time, for example, the order of information to be displayed may be changed according to the evaluation value or the viewing history information. The evaluation value is set based on the frequency extracted by the character extraction processing unit 204, the date and time of extraction, and the like. For example, if the extraction frequency is high and the extraction date is new, the evaluation value is increased. The evaluation value is lowered for those with a low extraction frequency and those with an old extraction date. Net content includes various information such as blog information and homepage information from which individuals send information, so various keywords are extracted. There may be no features. In this case, an evaluation value may be calculated using a keyword evaluation value that is semantically closer to natural language processing using an ontology, an associative thesaurus, or a corpus. Further, since the keyword included in the mail information is highly likely to be of interest to the user or related to the user, the keyword may be set higher, for example, by multiplying the evaluation value by 1.5 times. In addition, the communication unit 101 via the Internet 102 acquires ranking information indicating frequent keywords such as the number of searches by a search engine and the number of writings on a blog or a bulletin board, and sets an evaluation value according to the ranking information. May be.

  The character information extraction by the character extraction processing units 200 and 204 may be performed at a predetermined time interval, may be performed at a time interval set by the user, or the communication unit 101 or the broadcast receiving unit 105. It may be performed each time new content is received.

  Hereinafter, a method for a user to search for content from the content storage unit 103 using these table information will be described. FIG. 8 shows an example of a flowchart showing the search processing operation by the display calculation processing unit 202.

  First, when an instruction to start content search mode is input from the user via the user interface unit 112 (S801), the display calculation processing unit 202 causes the display unit 111 to select a content to be searched for. Is displayed (S802). Note that the content search mode activation instruction is not limited to being input from the user interface unit 112, and may be input from an external device such as a remote control device.

  FIG. 6 shows an example of the search target selection screen. The user selects the “broadcast” button 601 on the screen to obtain information from the broadcast content, and selects the “net” button 602 to obtain information from the net content. When it is desired to acquire information from both broadcast content and net content, both “broadcast” button 601 and “net” button 602 are selected.

  When the user selects the search target and then selects the triangular icon 603 on the screen using the interface unit 112, the search target is set (S803).

  When the search target is set, the display calculation processing unit 202 displays a screen for requesting input of the search condition on the display unit 111 (S804). FIG. 7 shows an example of the search condition input screen.

  In this example, as a search condition, “time series” sequentially extracted from new contents, “date and time” for searching contents corresponding to the date and time input by the user, news and mail selected by the user from the net table information, etc. “Current topic information” for searching for content corresponding to the keyword with the highest evaluation value in the genre, and “keyword” for searching for content corresponding to the keyword input by the user are provided.

  For example, by selecting “Mail” in “Information about the topic” as the search condition, the user does not have to review the email and consider which keywords are many, and enter the keywords without having to enter the keywords. You can search for content that has become a hot topic by email. In this example, the keyword extracted from the net table information is used as “current topic information”. However, when the broadcast table information has an evaluation value of the keyword as in the net table information, the broadcast is performed. You may make it search using the keyword of table information.

  6 and 7 are provided with browsing functions such as Web 2.0, BML (Broadcast Markup Language), HTML, Java (registered trademark) Script, broadcast XLET, CSS (Content Scrambling System), XML, and the like. Created in a description language that can be viewed on the device. Thus, items that can be input by the user can be easily added and deleted, and can be incorporated into various devices. In addition, by creating a method with a browsing function, etc., a home network connected by an IP network connected to the content display device 100, a plug-and-play, a network using a DLNA or a power supply network, etc. in the same manner as the remote control operation It can also be remotely controlled from the above devices.

When the user inputs a search condition and then selects the triangular icon 701 on the screen using the interface unit 112, the search condition is set (S805), and the display calculation processing unit 202 sets the search condition from the search target content. The content that has been found is searched (S806), and the search result is displayed on the display unit 111 (S807). In the content search S806, broadcast table information stored in the broadcast keyword storage unit 201 and net table information stored in the net keyword storage unit 203 are used. Search the character strings 201 and 203 for the date, keyword, genre, etc. set in the search conditions, and use the content viewing history and keyword evaluation values associated with the character string and date information, It has a function of extracting content with a high evaluation value.
As described above, according to the above-described search processing operation, for example, information that has become a topic in the network content can be confirmed also in the broadcast content. The convenience of information acquisition can be improved.

  Next, description will be made by taking as an example a case where broadcast content is selected as a search target and “mail” of “current topic information” is selected as a search condition. The display calculation processing unit 202 reads the keyword of the content whose genre is mail from the net table information shown in FIG. When a plurality of keywords are applicable, the search keyword having the largest evaluation value is determined from these. Next, the display calculation processing unit 202 extracts the content ID including the keyword corresponding to the search keyword from the broadcast table information shown in FIG. FIG. 9 shows an example of a search result display screen. A thumbnail 901 of the searched content and content related information 902 such as date information and viewing history included in the broadcast table information are displayed. Although only the thumbnails and the like of the three contents are shown on the screen of FIG. 9, when the triangle icon 903 on the screen is selected, other search results are displayed. When the thumbnail 901 is selected using the user interface 112, the display calculation processing unit 202 reads out from the corresponding content storage unit 103 and displays it on the display unit 111. This makes it possible for the user to easily review information that has become a hot topic from the broadcast content without having to input the keywords by reviewing the mail and examining which keywords are many. Also, by displaying the search results using thumbnails, the user can easily check the summary of information.

  In the above example, when there are a plurality of content keywords whose genre is mail in the net table information shown in FIG. 5, not only one keyword but also a plurality of items having a high evaluation value may be selected. Alternatively, all evaluation values having a predetermined threshold value or higher, such as 70%, may be selected. In this case, as shown in FIG. 9 (2), it is desirable to change the display method of the search result according to the evaluation value, for example, by changing the thumbnail size. By displaying in this way, the user can easily know which information should be emphasized. In addition, when there are a plurality of keywords, the corresponding content may be searched from the broadcast table information using all the keywords and displayed in the order of higher evaluation values. At this time, similarly to FIG. 9B, it is desirable to change the display of the search result in accordance with the evaluation value.

  In the above, the case where broadcast content is selected as a search target and “mail” of “current topic information” is selected as a search condition has been described as an example. However, when net content is selected as the search target, The search is similarly performed when “news”, “blog”, or the like is selected as a condition instead of “mail” or in addition to “mail”. However, it goes without saying that the broadcast table information need not be searched when only the net content is selected as the search target. When broadcast content and net content are selected as search targets, search results may be displayed separately or collectively.

  In addition, when a keyword or date / time is input from the user as a search condition, content information corresponding to the input keyword / date is read from broadcast table information or net table information. For example, when both broadcast content and net content are selected as search targets and “date and time” is input as a search condition, content corresponding to the date and time information of broadcast table information and the date and time information of net table information is searched. The search result is displayed as shown in 9 (3). In the example of FIG. 9 (3), the search results of the broadcast content and the net content are displayed separately. However, the present invention is not limited to this, and the broadcast content and the net content may be mixed and displayed. good.

  When “time series” is selected as the search condition, the search results are displayed in order from the newest date and time information of the broadcast table information and date and time information of the net table information.

  In the above example, an example is shown in which search conditions are selected one by one. However, the present invention is not limited to this, and a plurality of search conditions may be selected. For example, when “time series” and “keyword” are selected, the content information corresponding to the keyword is selected from the broadcast table information or the net table information, since the date information of the broadcast table information and the date information of the net table information are new. Display search results in order.

  Each embodiment mentioned above is an illustration for explanation of the present invention, and is not the meaning which limits the scope of the present invention only to an embodiment. Those skilled in the art can implement the present invention in various other modes without departing from the spirit of the present invention. For example, in the above description, the case of acquiring broadcast content and net content has been described. However, the present invention is not limited to this, and may be applied to the case of acquiring content transmitted by other transmission methods.
