The viewing process to be executed is executed. In this viewing process, a process of reproducing audio data included in the broadcast program data is also executed.

  The recording / playback processing unit 304 records the broadcast program data carried by the television broadcast signal of the predetermined channel selected by the TV tuner 117 under the control of the main processing unit 301 in the HDD 111 and the HDD 111. A reproduction process for reproducing the recorded broadcast program data is executed.

  The text information acquisition unit 305 acquires text information from the television broadcast signal of the channel to be viewed that is selected by the TV tuner 117 during the viewing process of the broadcast program data under the control of the main processing unit 301. The acquired text information is stored in the database 309. The database 309 includes a part of the storage area in the storage area of the HDD 111.

  The text information acquisition unit 305 acquires various data usable as text information from a television broadcast signal of a channel to be viewed. Data usable as text information includes, for example, subtitle information included in broadcast program data being viewed, electronic program information related to broadcast program data being viewed, and telop included in video data of broadcast program data being viewed. Audio data included in broadcast program data being viewed. The caption information included in the broadcast program data being viewed is included in, for example, table information called EIT that is carried by the television broadcast signal of the channel being viewed. The text information acquisition unit 305 selects at least one of the caption information, electronic program information, telop, and audio data as text information acquisition data, and acquires text information from each of the selected data. For example, at least one of caption information and electronic program information is used as default text information acquisition data. When acquiring text information from audio data, that is, when using audio data as text information acquisition data, the text information acquisition unit 305 recognizes voice data included in broadcast program data being viewed. The processing is executed, and the recognition result is stored in the database 309 as text information.

  The keyword extraction unit 306 extracts keywords from the sentence information by performing morphological analysis on the sentence information stored in the database 309 under the control of the main processing unit 301. The keyword extraction processing by the keyword extraction unit 306 is executed, for example, when the “interesting” button is operated by the user. In this case, not all text information stored in the database 309 is subject to keyword extraction processing, but text information stored in the database 309 during a certain period immediately before the “interesting” button is operated. Is selected as a processing target. In other words, only text information stored in the database 309 during a predetermined period from a time point a predetermined time before the “worried” button is operated to a time point when the “worried” button is operated. Will be processed. As a result, it is possible to process only text information including topics, words, etc., which the user is actually interested in, among text information accumulated during viewing of the broadcast program.

  The keyword extraction unit 306 not only extracts a plurality of keywords by performing morphological analysis on the text information to be processed, but also outputs words or priorities related to the keywords as additional information for each keyword. The word related to the keyword is, for example, a word representing an upper / lower concept of the meaning (category) of the extracted keyword. For example, if the keyword is “wine”, words such as “drink”, “France”, “red wine” are output as related words, and the priority is used for displaying a keyword list described later. Of keywords to be processed, keywords extracted from sentence information stored in the database 309 with a later timing, that is, extracted from sentence information stored at a timing closer to the point in time when the “interesting” button is operated. The higher the priority, the higher the keyword.

  Then, the keyword extraction unit 306 stores the keyword group and additional information extracted in this way in the database 309. At this time, the keyword extraction unit 306 acquires time information at the time when the “interesting” button is operated, and together with the keyword group. Store in the database 309.

  The keyword list display unit 307 generates a keyword list indicating a list of keywords extracted by the keyword extraction unit 306 under the control of the main processing unit 301, and uses the generated keyword list as a topic that the user is interested in. The memo information in which the words or the matters to be remembered are written down is displayed on the display device such as the LCD 17. In this case, the keyword list display unit 307 gives priority to the keyword extracted from the sentence information stored in the database 309 with the latest timing among the keywords extracted from the sentence information to be processed based on the above-described priority. To generate a keyword list. For example, a keyword list in which keywords are arranged in descending order of priority is generated. In addition, since the upper limit of the number of keywords that can be displayed in the keyword list is determined in advance, when keywords exceeding the predetermined number n are extracted by the keyword extraction unit 306, a higher priority is assigned. A keyword list is generated from only n keywords.

  The keyword extraction by the keyword extraction unit 306 is performed every time the “interesting” button is operated. Accordingly, the keyword list generated by the keyword list display unit 307 is updated every time the “interesting” button is operated. As described above, when storing the extracted keyword in the database 309, the keyword extracting unit 306 also stores in the database 309 time information at the time when the “interesting” button is operated. Therefore, the keyword list display unit 307 has an interface for presenting this time information in a time series as a history, and by operating the time information presented in the time series as this history, the “interesting” button is operated in the past. Provide a mechanism to reproduce the displayed keyword list as needed.

  The information acquisition processing unit 308 is selected by the user from the displayed keyword list by executing communication with a predetermined server device on the Internet via the network controller 114 under the control of the main processing unit 301. Get information related to the keyword from the Internet. Specifically, when a keyword is selected by the user from the keyword list, the information acquisition processing unit 308 uses the selected keyword as a search term to a predetermined server device on the Internet via the network controller 114. By transmitting, information matching the search term is acquired from the Internet, and the acquired information is displayed on a display device such as the LCD 17.

  In this case, in order to obtain more accurate information from the Internet, the information acquisition processing unit 308 uses not only the selected keyword but also a word added as additional information to the selected keyword as a search term. Send to.

  The server device requests a search for information matching the search word received from the computer 10 to a predetermined search server on the Internet, so that information matching the search word from the search server (for each WEB page matching the search word). A location information URL and a title / summary of each WEB page are acquired, and a search result page is generated based on the acquired information, and the search result page is transmitted to the computer 10.

  Next, with reference to FIG. 4 and FIG. 5, the flow of processing executed during viewing processing of broadcast program data will be described. FIG. 4 shows a data flow, and FIG. 5 shows an example of a keyword list and a search result page.

  As described above, during viewing processing of broadcast program data, text information is acquired from subtitles, electronic program information, telop, audio data, and the like, and stored in the database 309. For example, as shown in FIG. 5A, when the broadcast program data being viewed is included in the caption information, the caption information is decoded and stored in the database 309 as text information. Each acquired text information is stored in the Daders 309 together with time information, for example.

  When a predetermined user operation such as pressing the above-mentioned “interesting” button is performed during the viewing process of the broadcast program data, the keyword extracting unit 306 executes the keyword extracting process. As described above, the sentence information to be subjected to the keyword extraction process is the sentence information accumulated in the database 309 for a certain period immediately before the time when a predetermined user operation such as pressing the “worried” button is performed. It is. The keyword extraction unit 306 divides the sentence information into words by performing morphological analysis on the sentence information using a morphological analysis engine, and thereby extracts a plurality of keywords. Further, the keyword extraction unit 306 performs semantic analysis of each keyword using a semantic analysis engine, and adds and outputs additional information such as a related word to each keyword. FIG. 6 shows an example of storing extracted keywords in the database 309. As shown in FIG. 6, the extracted keywords are stored in the database 309 along with time information in units of operation of the “interesting” button.

  A list of extracted keywords is displayed on the LCD 17 as a keyword list. FIG. 5B shows an example of a keyword list. As shown in the figure, on this keyword list, a field a1 for presenting time information when the “interesting” button is operated in time series as a history is displayed together with a field a2 for displaying a list of keywords. Is provided. This field a1 is configured as a pull-down menu, and when a specific button at the right end is operated, as shown in FIG. 7A, time information when the “interesting” button has been operated in the past is selected as an option. Display a list. Then, when any one of the time information displayed as a list is selected, as shown in FIG. 7B, the keyword list is changed to a keyword list for listing keywords corresponding to the time information. Switch.

  That is, for example, the user operates the “Worry” button at 22:00 on Thursday, May 24 to display the keyword list at that time (FIG. 5B), As shown in FIG. 7A, by displaying a list of time information in the field a1 on the keyword list and selecting 21:35 on May 23 (Wednesday) from that list, As shown in the figure, it is possible to redisplay the keyword list displayed when operating the “Worry” button at 21:35 on May 23 (Wednesday), which is the past. .

  When a keyword is selected from the keyword list by the user, the selected keyword and a word related to the keyword are transmitted to the server device 411 as a search word. For example, the server device 411 converts the search term into a URL for transmitting a search request including the search term to a predetermined search server 412, and searches for a search for information that matches the search term using the URL. Request to server 412. Then, the server device 411 receives the search result from the search server 412, generates a predetermined search result page that can be handled by the TV application 202 based on the received search result, and stores the search result page in the computer 10. Send to.

  FIG. 5C shows an example of a search result page displayed on the LCD 17 of the computer 10. This search result page corresponds to the case where the selected keyword “squid” and the related word “buy” are transmitted to the server device as search terms. For example, the server device transmits a search request for “squid” and an AND search request for “squid” and “buy” to the search server, and based on the search result, a search result page as shown in FIG. Is generated and transmitted to the computer 10. When the user selects the “Search” tab on the search result page, the search result corresponding to the search request for “squid” is displayed. When the tab is selected, search results corresponding to AND search requests of “squid” and “buy” are displayed.
