(Usage example 1 of TV with built-in PC)
One example of use of the PC built-in television 1 will be described with reference to FIG. FIG. 5 is a sequence diagram showing a flow of information processing in one example of use of the PC built-in television 1.

  First, the content acquisition unit 22 requests an electronic newspaper from the Internet 8 (step S101), and acquires the electronic newspaper (step S102). In step S101, the electronic newspaper is searched and acquired based on a preset keyword. The keyword is registered in advance by the user, for example, stored in the storage unit 24.

  Next, the content processing unit 21 extracts characters from the electronic newspaper (step S103). Even if the electronic newspaper is an image, characters are extracted by analyzing the characters included in the image. Next, the content processing unit 21 confirms the presence or absence of the above-described keyword in the extracted characters, and then a keyword, an electronic newspaper headline, a character string that understands the article content (for example, the first 30 characters of the article body), Photo information is extracted to create a list (step S104).

  On the other hand, the content acquisition unit 15 receives a broadcast program (step S105). Next, the content transmission unit 32 transfers the broadcast program to the content reception unit 29 (step S106). Next, the content processing unit 21 extracts keywords included in the broadcast program from the broadcast program (step S107). If the keyword cannot be extracted, a character string close to the keyword is extracted. The character string close to the keyword includes, for example, a character string that is replaced with only one character or a character that is missing only one character.

  Next, the content processing unit 21 determines whether or not the genre of the broadcast program is news (step S108). For example, when the broadcast program is a digital broadcast, the information indicating the genre is associated with this determination, and thus the determination is made based on the information indicating the associated genre. In the case of analog broadcasting, the genre may be identified by analyzing audio and images. If the broadcast program is news, the process proceeds to step S109.

  In step S109, the degree of coincidence representing the depth of association between the keyword extracted from the broadcast program and the electronic newspaper is calculated by comparing the keyword with the list. As the calculation method, for example, the number of times a keyword appears in the second content may be used as the degree of matching, or the number of times the keyword appears per specific number of characters may be used as the degree of matching. Also, if keywords cannot be extracted from the broadcast program and instead a character string similar to the keyword can be extracted, the similarity between the keyword and the character string (for example, the number of duplicate characters, etc.) matches It may be a degree. After calculating the degree of coincidence, the degree of coincidence is added to the list.

  Next, when the user requests display of the list via the remote controller 9, the request is sent to the control information communication unit 25 of the PC unit 20 (step S110). When the control information communication unit 25 accepts the request, the content processing unit 21 removes those with a low matching degree from the list (step S111). That is, the order of priority set in the present invention means that the degree of coincidence is set as a priority, the lower ones are excluded, and the rest are arranged. Further, the rest may be arranged in descending order of coincidence. If the broadcast program is not news, the list is left as it is.

  Next, the content processing unit 21 sends the list to the content reception unit 16 via the content transmission unit 23 (step S112), and the video output unit 11 displays the list on the display 2 (step S113).

  According to this use example, when a broadcast program including a keyword predetermined by the user is broadcast, the user views a list in which headlines of newspaper articles related to the keyword are arranged in descending order of the keyword. Can easily access articles that the user is interested in.

(Usage example 2 of PC built-in TV)
One use example of the PC built-in television 1 will be described with reference to FIGS. FIG. 6 is a diagram showing an example of a screen in one example of use of the PC built-in television 1. FIG. 7 is a sequence diagram showing a flow of information processing in one example of use of the PC built-in television 1.

  First, the screen of the display 2 in this usage example will be described with reference to FIG. In this usage example, while the baseball broadcast is displayed on the screen 201, the baseball player information, the blog, and the supporting HP information are displayed on the screen 202. The player displayed on the screen 202 is switched to the player A, the player B, and the player C every 10 seconds as shown in FIG. The order of the displayed players is determined based on the list L201. The content processing unit 21 creates this list L201. In the list L201, players are listed in order, and information on the players, URLs of blog sites, URLs of supporting HPs, and the like are associated with each other. The top of the list is switched sequentially. That is, after displaying the player A, the player A is once sorted at the end of the list L201, and then displayed for the player B who comes to the top of the list L201. This is because in the list L201, the players are arranged in the order of cheering levels described later, and once the information about the players is displayed on the screen 202, the cheering level is cleared (set to zero).

  Next, information processing when creating the list L201 will be described with reference to FIG. First, a request is made to the Internet 8 for the name of a player participating in a baseball game on the day of using the PC built-in television 1 (which will be a keyword in this use example) (step S201) and acquired (step S202). Next, the content processing unit 21 lists the acquired data (player name) (step S203).

  On the other hand, the content acquisition unit 15 receives a broadcast program (step S204). Next, the content transmission unit 32 transfers the broadcast program to the content reception unit 29 (step S205). Next, the content processing unit 21 determines whether or not the genre of the broadcast program is a baseball broadcast (step S206). For example, if the broadcast program is a digital broadcast, information indicating a genre is associated with this determination. Therefore, the determination may be made based on whether this information is a baseball broadcast or an analog broadcast. Alternatively, image analysis may be performed and a determination may be made based on a person's uniform in the image. If the genre of the broadcast program is baseball broadcast, the process of step S207 is performed. If the genre of the broadcast program is not a baseball broadcast, the PC unit 20 ends the process, and the TV unit 10 continues to play the broadcast program.

  In step S207, a player name as a keyword is extracted from the broadcast program. For example, in the case of digital broadcasting, if information about the player name currently displayed is associated, the player name may be extracted. If such information is not associated, the video is analyzed. The player's name may be extracted by extracting the spine number as the relevant information of the keyword and collating with the Internet or a pre-registered database from the related information. At the same time, in step S207, the loudness of the cheering sound (cheering level; numerical information) is measured and extracted as keyword related information. Then, in addition to the list in association with the player name, the player names are sorted in descending order of cheering level. In addition, what is necessary is just to calculate the cheering level per one player name as a total value of the cheering level detected within the predetermined time, for example, after acquiring one player's name. The predetermined time may be stored in the storage unit 24 or the like, or the user may register, for example, “within 10 seconds after detecting the player name”.

  Next, information on the first player in the list L201, a blog, and a supporting HP are searched (step S208), and their data are obtained (step S209). Next, a screen of the player information, blog, and supporting HP to be displayed on the screen 202 described above is created and transmitted to the content receiver 16 of the TV unit 10 (step S210). The video output unit 11 displays the screen on the screen 202 (step S211). The content processing unit 21 clears the cheer level for the player once displayed on the screen 202 (sets it to zero) (step S212). Thereby, the said player is rearranged to the end of the list, and is repeated from step S208 for the next player who becomes the top of the list.

  According to this usage example, when viewing a broadcast program of a baseball game, the user can also check HP headlines such as HPs and blogs supporting the players in the order of popularity of the players. .

(Usage example 3 of PC built-in TV)
One use example of the PC built-in television 1 will be described with reference to FIGS. FIG. 8 is a diagram showing an example of a screen in one example of use of the television 1 with a built-in PC.

  Next, information processing for updating the lowest price of a product using the lowest price application will be described with reference to FIG. First, based on a product name (which is a keyword in this use example), an electronic advertisement on which a product is posted is requested from the Internet 8 (step S301) and acquired (step S302). Next, price information (numerical information) is extracted from the electronic advertisement and added to the list of products (step S303). This list is a list of a plurality of sales destinations for one product, and price information of each sales destination is associated therewith. Next, the price information acquired this time is compared with the price information listed so far (step S304). Here, when the lowest price has been updated for a sales destination already listed, the price information is updated, and the price information of a new sales destination not listed is obtained in step S302. In this case, the seller and price information are added to the list. In the display list, sales destinations are rearranged so that price information is in ascending order. In this usage example, the case where price information is obtained from both a broadcast program and an electronic advertisement searched from the Internet 8 is described as a list. However, the list is an electronic advertisement searched from the Internet 8. It may be a list of only price information acquired from.

  On the other hand, the content acquisition unit 15 receives a broadcast program (step S305). Next, the content transmission unit 32 transfers the broadcast program to the content reception unit 29 (step S306). Next, the content processing unit 21 extracts the product name and price information from the broadcast program (step S307). For example, a program image is analyzed, a character string indicating a product name and a character string indicating price information are extracted, and a product name and price information are extracted. Next, the price information obtained in step S307 is compared with the price information listed in the corresponding product list (step S308). At this time, the content processing unit 21 may recognize only the comparison result between the price in the broadcast program being played and the price listed in the list, or by adding the price in the broadcast program to the list and creating a new one. You may create a list.

  Next, when the user sends an instruction to display the lowest price of the product to the PC built-in television 1 via the remote controller 9, the user input unit 17 receives the instruction, and the control information communication unit 18 performs control information communication. A display request for a screen for displaying the lowest price is transmitted to the unit 25 (step S309). Next, the content processing unit 21 creates a screen for displaying the lowest price (step S310). This screen is the screen 302 shown in FIG. Next, the screen information created by the content processing unit 21 is transmitted from the content transmission unit 23 to the content reception unit 16 (step S311), and after being synthesized with the screen information for displaying the broadcast program by the content synthesis unit 14, the video is displayed. The output is output from the output unit 11 to the display 2, and the display 2 displays the screen (step S312).

  Next, when the user selects the icon I301 and presses the enter button on the remote controller 9, a request for displaying the lowest price information is transmitted from the control information communication unit 18 to the control information communication unit 25 (step S313).

Next, the storage unit 24 stores the viewing reservation program and the recording reservation program.

  When the user views / reproduces the broadcast program stored in the storage unit 24 (step S405), information indicating which broadcast program is viewed / reproduced is transmitted to the content processing unit 21 (step S406). . The content processing unit 21 recognizes to which keyword the viewed / reproduced broadcast program corresponds, and adds 1 to the number of times of viewing (numerical information) associated with the keyword (step S407). Here, the keyword for adding the number of times of viewing may include not only the keyword used when searching for the broadcast program but also a keyword extracted from the broadcast program that matches the keyword registered in advance. For example, when “news” is searched for as a keyword, and a sports news program is searched and viewed, “sports” is also registered in advance, and genre information associated with the sports news program, etc. When the keyword “sports” is extracted from “1”, the number of viewing times associated with “news” and “sports” in the list is incremented by one. The viewing count may be stored in the storage unit 24 or the like in association with the keyword. In addition, the period for adding the number of views is determined within a predetermined period after the keyword is registered by the user, and after the predetermined period, the number of views is returned to 0, and the addition is newly started. Alternatively, it may be added forever without setting a predetermined period, or the number of viewing times may be manually reset to 0 by the user.

  Next, the content processing unit 21 rearranges the keywords in the descending order of the number of times of viewing the list, with the number of times of viewing as a priority (step S408).

  When the user requests display of the electronic newspaper via the remote controller 9, the control information communication unit 18 transmits an instruction to display the electronic newspaper to the control information communication unit 25 (step S409). Next, the content acquisition unit 22 requests an electronic newspaper from the Internet 8 (step S410), and acquires telegraph data (step S411). The content processing unit 21 extracts character information from the acquired electronic newspaper data (step S412).
