<Embodiment 1>
FIG. 1 is a block diagram of an information processing apparatus 1 according to Embodiment 1 of the present invention. As shown in FIG. 1, the information processing apparatus 1 according to the first embodiment displays a program-related information related to the contents of a digital broadcast program together with a video of the program, and receives a digital broadcast signal. An information acquisition unit 11 that acquires program content information included in the digital broadcast signal, a semantic analysis unit 12 that extracts words from the program content information, and a program-related information target from the words extracted by the semantic analysis unit 12 A target selection unit 13 that selects words, a target survey unit 14 that searches and extracts program-related information based on the word selected by the target selection unit 13, and synthesizes and outputs the program-related information and the program video. A synthesizing unit 18, and the processing in each of the semantic analyzing unit 12, the target selecting unit 13, and the target examining unit 14 uses an arbitrary service on the Internet 2. It is a symptom.

  Next, the operation of the information processing apparatus 1 according to the first embodiment will be described.

  In the digital broadcast receiving unit 10, for example, data included in a digital broadcast signal transmitted from a broadcasting station that is received by a receiving antenna (not shown) provided in the information processing apparatus 1 is input. The input data includes data such as video, audio, various SIs (Service Information: program arrangement information), subtitles, data broadcasting, etc., and these data are mixedly input. These data are output to the information acquisition unit 11. The digital broadcast signal does not necessarily have to be distributed in a broadcast form, and may be distributed through a network or individually in any unit such as a program or content.

  The information acquisition unit 11 acquires information (program content information) related to the content of the broadcast program from various data input from the digital broadcast reception unit 10. As the information, subtitle data, section data (SI information data, in particular, an EIT (Event Information Table) section used for presenting an electronic program guide, an SDT (Service Description Table) section, etc.) can be used. And character string information extracted from character supermarkets and data broadcasting. Also, the character string information obtained by recognizing the image included in the image data and the character string information representing the semantic content of the moving image and the character string information obtained by extracting the character string (eg, telop) included in the moving image is used. be able to.

  The semantic analysis unit 12 extracts words from the program content information input from the information acquisition unit 11. FIG. 2 is a flowchart of the semantic analysis unit 12 according to the first embodiment of the present invention. As shown in FIG. 2A, when program content information is input from the information acquisition unit 11 in step S121, processing for analyzing the meaning of the program content information (extracting words from the program content information). Is started and the process proceeds to step S122.

  In step S122, it is determined whether the input information is a sentence or a word. And when it is judged that it is a sentence, it transfers to step S123, and when it is judged that it is a word, it transfers to step S124 and complete | finishes a process.

  In step S123, the sentence determined in step S122 is broken down into words that can mean program content. Here, the word that can mean the program content is, for example, a noun (particularly, a noun representing a time or place, a person's name, etc.) included in a sentence.

  FIG. 2B is a flowchart showing details of the process in step S123. As shown in FIG. 2B, in step S1231, a process of extracting a word from the sentence determined in step S122 is started, and the process proceeds to step S1232.

  In step S1232, a text analysis method to be used is selected from text analysis services on the Internet 2. The service selection may be performed by a user operation, may be fixedly selected, or may be automatically selected. For example, Yahoo! There is a “Japanese morphological analysis Web API” provided by Japan.

  In step S1233, a query format corresponding to the sentence analysis service selected in step S1232 is generated. For example, the “Japanese morphological analysis Web API” has a query format in which a sentence to be analyzed is embedded in a specified URI (Uniform Resource Identifier) format. Also, a format using a SOAP (Simple Object Access Protocol) command may be used.

  In step S 1234, the query generated in step S 1233 is transmitted to the service providing site on the Internet 2 via the network IF unit 15.

  In step S 1235, a response from the service providing site of the query transmitted in step S 1234 is acquired via the network IF unit 15. For example, in the above-mentioned “Japanese morphological analysis Web API”, it is transmitted in the XML format which is a prescribed format.

    In step S1236, the content of the response acquired in step S1235 is analyzed. As the content of the analysis, since the acquired response includes information obtained by decomposing the original sentence into words, a process for extracting those words is performed. After step S1236, the process proceeds to step S1237 to end the process.

  The target selection unit 13 selects a word that is a target of information (program related information) related to the contents of a digital broadcast program from the words extracted by the semantic analysis unit 12. FIG. 3 is a flowchart of the object selection unit 13 according to the first embodiment of the present invention. As shown in FIG. 3, in step S131, a process of selecting a word that is a target of program-related information from words input from the semantic analysis unit 12 is started, and the process proceeds to step S132.

  In step S132, a service to be used is selected from services on the Internet 2 that perform word weighting in order to select a word as a target of program-related information. The service selection may be performed by a user operation, may be fixedly selected, or may be automatically selected. For example, as a holistic approach to selecting a target word, the Simpson coefficient was calculated based on the number of word hits of the search engine to calculate the closeness (correlation strength) between the words. When a word that is a target of program-related information is selected based on the result, the selection in step S132 includes, for example, “web search” that can obtain the number of word hits of a search engine.

  In step S133, a query format corresponding to the service selected in step S132 is generated.

  In step S134, the query generated in step S133 is transmitted to the service providing site on the Internet 2 via the network IF unit 15.

  In step S135, a response is acquired from the service providing site of the query transmitted in step S134 via the network IF unit 15.

  In step S136, the content of the response acquired in step S135 is analyzed. As the content of the analysis, in the case of the above approach, the number of search hits is extracted from the acquired response, and the target word is selected based on the extracted number of search hits. After step S136, the process proceeds to step S137 to end the process.

  The target research unit 14 investigates and extracts program-related information based on the word selected by the target selection unit 13. FIG. 4 is a flowchart of the target investigation unit 14 according to the first embodiment of the present invention. As shown in FIG. 4, when a word selected by the target selection unit 13 is input in step S141, a process for investigating and extracting program-related information based on the word is started in step S142. Transition.

  In step S142, a service to be used is selected from services on the Internet 2 that provide information related to the word selected by the target selection unit 13. The service selection may be performed by a user operation, may be fixedly selected, or may be automatically selected.

  For example, the service for providing information related to the word selected by the target selection unit 13 may be a dictionary / dictionary that explains / explains the semantic content of the selected word. It may be the number and ranking searched for, or it may be news or a blog that contains the selected word, and if the selected word is location information, it may be map information indicating the location, and the selected word Site information and shopping information that can be purchased. In addition to the above, any service may be used as long as the service obtains related information based on the selected word.

  In step S143, a query format corresponding to the service selected in step S142 is generated.

  In step S144, the query generated in step S143 is transmitted to the service providing site on the Internet 2 via the network IF unit 15.

  In step S145, a response is acquired from the service providing site of the query transmitted in step S144 via the network IF unit 15.

  In step S146, the content of the response acquired in step S145 is analyzed. As the content of the analysis, when a dictionary service among the above services is used, a process of extracting word semantic information from the acquired response is performed. After step S146, the process proceeds to step S147 to end the process.

  The result drawing unit 16 receives the program related information extracted by the target examining unit 14 and draws the content of the input program related information on the graphics base. The rendered bracket data is output to the composite display unit 18 (composite unit).

  The digital broadcast presentation unit 17 receives the digital broadcast signal output from the digital broadcast reception unit 10 and converts the content of the input digital broadcast signal into presentation data such as video display data. The converted presentation data is output to the composite display unit 18.

  In the composition display unit 18 (composition unit), the graphics data (program related information) output from the result drawing unit 16 and the presentation data (program video) output from the digital broadcast presenting unit 17 are input, and both data Are combined to generate one screen data. The generated screen data is output outside the information processing apparatus 1.

  From the above, since the processing in each of the semantic analysis unit 12, the target selection unit 13, and the target survey unit 14 is performed using any service on the Internet 2, information related to the program is acquired. While reducing the operation by the user at the time of display, the processing load of the information processing apparatus 1 is reduced.
