The text storage unit 11 creates a keyword list 20 although details will be described later.

Although the details will be described later, the search control unit 12 performs a process for performing a web search on the Internet 4.

The communication unit 13 has a function of connecting to the Internet 4 via a network. The search control unit 12 can access an arbitrary URL (Uniform Resource Locator) via the communication unit 13.

Next, the operation of this embodiment will be described. In the following, the processing performed by the information processing apparatus 30 will also be referred to as "web search-related processing". In order to make it easier to understand an example of the web search related processing, the web search related processing performed under the following premise Pm1 will be described.

In the premise Pm1, the signal processing unit 9 receives the content signal. Further, in the premise Pm1, the content signal received by the signal processing unit 9 includes character information indicating a plurality of character strings and a video (video signal).

In the web search-related processing in the premise Pm1, first, the signal processing unit 9 receives the content signal including the character information. The signal processing unit 9 performs signal processing on the received content signal, and transmits the content signal to the text extraction unit 10 and the content processing unit 14.

Next, noun extraction processing is performed. In the noun extraction process, the text extraction unit 10 extracts one or more nouns from the character information included in the received content signal. Specifically, the text extraction unit 10 acquires character information (language information) from the received content signal, and extracts a plurality of nouns from the character information. The text extraction unit 10 transmits the extracted plurality of nouns to the text storage unit 11.

Next, the keyword list creation process is performed. In the keyword list creation process, the text storage unit 11 creates a keyword list 20 indicating one or more nouns. Specifically, the text storage unit 11 stores a plurality of received nouns and creates a keyword list 20 that lists the plurality of nouns. The created keyword list 20 is, for example, the keyword list 20 of FIG.

In FIG. 3, among the plurality of nouns transmitted by the text extraction unit 10 to the text storage unit 11, the latest k nouns are shown in the keyword list 20. "K" is a natural number. Further, "k" is a preset value. The nouns extracted by the text extraction unit 10 in the past may be summarized as "other keywords". The number of nouns shown in the keyword list 20 is not limited to a plurality, and may be 1.

Further, when the same noun as the latest noun transmitted by the text extraction unit 10 to the text storage unit 11 is shown in the keyword list 20, the latest noun may not be shown in the keyword list 20. This makes it possible to prevent duplicate display of nouns.

The search control unit 12 performs a process of displaying the keyword list 20 on the output unit 50. Specifically, the search control unit 12 causes the created keyword list 20 to be displayed on the display unit 51 of the output unit 50 via the content processing unit 14. More specifically, the search control unit 12 transmits the keyword list 20 to the content processing unit 14. The content processing unit 14 causes the keyword list 20 to be displayed on the display unit 51 of the output unit 50.

In the following, the noun that the user wants to use as a keyword for web search is also referred to as "noun A".

Next, the user performs a selection operation. The selection operation is, for example, an operation for selecting a noun A from a plurality of nouns indicated by the keyword list 20 displayed on the display unit 51 of the output unit 50. Further, the selection operation is an operation performed on the main body operation unit of the television receiver 100 or the remote controller.

In the following, a noun selected from one or more nouns shown in the keyword list 20 is also referred to as a “selected noun”. The selected noun is, for example, a noun (character string) shown in white in FIG. When the selection operation is performed, the operation unit 5 receives an operation signal indicating the selection noun. The operation unit 5 transmits the operation signal to the search control unit 12.

Here, it is assumed that the selected noun is, for example, the "other keyword" shown in FIG. In this case, a plurality of nouns transmitted by the text extraction unit 10 to the text storage unit 11 in the past may be displayed in a list.

Next, a web search process is performed. In the web search process, the search control unit 12 uses the selected noun to perform a process for performing a web search on the Internet 4. That is, the search control unit 12 uses the selected noun to perform a process for searching a web page via the Internet 4.

Specifically, the search control unit 12 performs the following processing. First, the search control unit 12 identifies the selected noun based on the operation signal received from the operation unit 5. Next, the search control unit 12 performs a web search for the selected noun via the communication unit 13. Specifically, the search control unit 12 controls the communication unit 13 so that the communication unit 13 uses the selected noun to perform a web search on the Internet 4. As a result, the communication unit 13 acquires the search result accompanying the execution of the web search, and transmits the search result to the search control unit 12.

In the following, the image showing the search result is also referred to as “search result image 21”. The search result image 21 is, for example, the search result image 21 of FIG. The search result image 21 in FIG. 4 is, for example, an image showing a web browser showing the search results.

When the search control unit 12 receives the search result, it generates a search result image 21 showing the search result.

Next, result output processing is performed. In the result output process, the search control unit 12 performs a process of displaying the search result obtained by the web search on the output unit 50. Specifically, in the result output process, the search control unit 12 performs a process of displaying the search result image 21 on the display unit 51 of the output unit 50 via the content processing unit 14. More specifically, the search control unit 12 transmits the search result image 21 to the content processing unit 14.

The content processing unit 14 receives the content signal from the signal processing unit 9. Therefore, the content processing unit 14 controls the display unit 51 so that the display unit 51 displays the image in which the keyword list 20 and the search result image 21 are superimposed on the image included in the content signal.

Specifically, the content processing unit 14 transmits a control signal for controlling the display unit 51 to the output unit 50. The control signal is a signal for displaying the keyword list 20, the search result (search result image 21) obtained by the web search, and the video included in the content signal on the display unit 51 of the output unit 50. The control signal includes a keyword list 20, a search result image 21, and an image included in the content signal. In addition, the control signal further includes audio included in the content signal.

As a result, as shown in FIG. 5, the display unit 51 displays, for example, the image G1 on which the keyword list 20 and the search result image 21 are superimposed according to the control signal. The video G1 is, for example, a video showing a broadcast program. Further, the video G1 is, for example, a video as content reproduced by the external device 3.

The audio output unit 52 of the output unit 50 outputs the audio included in the control signal in response to the reception of the control signal. The sound is, for example, a sound corresponding to the video G1.

In the result output process, the keyword list 20 may not be displayed on the display unit 51. In this case, the control signal is a signal for displaying the search result (search result image 21) and the video included in the content signal on the display unit 51 of the output unit 50.

Further, the search result image 21 displayed on the display unit 51 may be changed to an arbitrary size according to the operation signal received by the operation unit 5 in response to the user operation. The user operation is an operation performed by the user on the main body operation unit or the remote controller.

Further, the display / non-display switching setting of the keyword list 20 or the search result image 21 displayed on the display unit 51 may be changed by the operation signal received by the operation unit 5 in response to the user operation.

As described above, according to the present embodiment, the text extraction unit 10 extracts one or more nouns from the character information included in the content signal. The text storage unit 11 creates a keyword list 20 indicating the one or more nouns. The search control unit 12 performs a process for performing a web search on the Internet by using a selected noun which is a noun selected from one or more nouns shown in the keyword list 20.

As a result, the character information included in the content signal can be effectively utilized in the situation where the information processing apparatus 30 performs a web search.

Further, according to the present embodiment, the text extraction unit 10 acquires character information (language information) from the content signal and extracts a plurality of nouns from the character information. Then, a keyword list 20 that lists a plurality of nouns is automatically created. The video included in the content signal is displayed on the display unit 51. That is, a keyword list 20 relating to an object that is displayed on the display unit 51 and is highly relevant to the video that the user is viewing is automatically created. The target is, for example, an object, a person, a place, or the like. The video displayed on the display unit 51 is a broadcast program, played content, or the like.

Then, a web search is performed using the nouns selected by the user from the plurality of nouns shown in the keyword list 20. Therefore, the user can search the Web without actively performing the voice input operation and the character input operation. The voice input operation is an operation in which a user makes a voice input by emitting a voice. The character input operation is an operation of inputting characters using a personal computer, a mobile terminal, or the like.

Therefore, the Web search can be performed only by selecting a noun from the automatically created keyword list without the user actively performing a voice input operation or the like. As a result, the convenience of the user can be improved.

Further, according to the present embodiment, the information processing device 30 includes a storage unit 8. Here, it is assumed that the text extraction unit 10 extracts a large number of keywords and the user loses sight of the keywords that he / she wants to search the Web. Even in this case, a desired keyword can be easily searched for by checking the program (recorded program) stored in the storage unit 8.

When performing a web search using the voice recognition result recognized in the related configuration A, it is necessary for the user to actively emit voice to the AV device. Therefore, there is a problem that it is difficult for a user who is reluctant to talk to an AV device to use the AV device.

Therefore, the information processing device 30 of the present embodiment has a configuration for achieving the above effects. Therefore, the information processing device 30 of the present embodiment can solve the above-mentioned problems.
