Furthermore, the digital broadcast receiving apparatus according to the present embodiment is connected to the person database server 14 and various servers 15 via the network IF unit 11. The person database server 14 is a server that holds a person database 14a in which a person's name and the reference face image data of the person are associated, and the various servers 15 are Web servers or the like.

  The antenna 1 is a parabolic antenna or a UHF antenna that receives a digital broadcast signal, and outputs the received digital broadcast signal to the tuner 2.

  The tuner 2 selects a physical channel desired by the user from the input digital broadcast signal and outputs it to the demodulator 3.

  The demodulator 3 performs error correction processing, demodulation processing, and the like on a digital broadcast signal encoded with a transmission path, and a transport stream in which video data, audio data, and the like constituting a program desired by a user are multiplexed in an MPEG2 system And output to the demultiplexer unit 4.

  The demultiplexer unit extracts program data (video data packet, audio data packet, etc.), program specific data (PAT packet, PMT packet, etc.) and program arrangement data (EIT packet, etc.) from the input transport stream, and video Data and audio data are output to the MPEG decoder unit 5.

  The MPEG decoder unit 5 performs MPEG decoding of the MPEG encoded video data and audio data, outputs the decoded video data to the display unit 13, and outputs the audio data to the speaker 12.

  The OSD processing unit 6 synthesizes OSD (On Screen Display) with the video data output from the MPEG decoder unit 5 in accordance with the notification from the control unit 9. The OSD is graphics composed of characters such as menus and images, and is displayed on the display unit 13 by being superimposed on video data.

  The flash ROM 7 is a recording medium in which application programs and data for the digital broadcast receiving apparatus are stored in advance. The flash ROM 7 stores a person database 7a in which a person's name is associated with the reference face image data of the person. However, when the capacity of the flash ROM 7 is small, the person database 7a may be omitted. Further, the flash ROM 7 is provided with a person information cache area 7b for temporarily storing person information.

  The RAM 8 executes an application program of the digital broadcast receiving device developed from the flash ROM 7. Further, although not shown, when the capacity of the RAM 8 is large, a personal information cache area for temporarily storing personal information may be provided in the RAM 8.

  The control unit 9 is connected to the tuner 2, demodulation unit 3, demultiplexer unit 4, MPEG decoder unit 5, OSD processing unit 6, flash ROM 7, RAM 8, key receiving unit 10, network IF unit 11, and the entire digital broadcast receiving apparatus. Control.

  Further, the control unit 9 includes a face image data automatic extraction unit 9a, a person identification unit 9b, a person list construction unit 9c, a person list display unit 9d, a person selection unit 9e, a person information construction unit 9f, Information display means 9g. Hereinafter, the control unit 9 will be described in detail.

  The face image data automatic extracting unit 9 a extracts face image data of all persons included in the video displayed on the display unit 13 and stores the extracted face image data in the RAM 8. In addition, after extracting the face image data of all persons, the face image data is extracted again after a certain time has elapsed.

  As an extraction method in the face image data automatic extracting means 9a, for example, a screen shot of a video displayed on the display unit 13 is taken, and face image data of all persons is obtained by performing face image recognition processing on the captured image data. Can be extracted.

  The person specifying means 9b first obtains the name of a program character from the program information included in the program arrangement data extracted by the demultiplexer unit 4.

  Next, the person specifying means 9b collates the face image data extracted by the face image data automatic extracting means 9a with the reference face image data of the person registered in the person database 7a or the person database 14a. As a result of the collation, a plurality of reference face image data having a high similarity rate to the face image data are extracted, and the person of the reference face image data whose name matches the name of the person in the extracted reference face image data and the character name Is identified as a person in the face image data. When the names do not match and when the character name does not exist in the program information, the person of the reference face image data with the highest similarity is specified as the person of the face image data.

  The person list construction unit 9c constructs a person list in which the name of the person identified by the person identification unit 9b is associated with the face image data of the person. At this time, if the name of the person specified by the person specifying means 9b is already registered in the person list, the person list construction means 9c does not add the person to the person list.

  The person list display unit 9d notifies the OSD processing unit 6 of the name of the person registered in the person list and the face image data of the person, and displays the person list on the display unit 13.

  The person selection means 9e displays a cursor for selecting a person together with the person list displayed on the display unit 13, and moves the cursor by the user's operation of the up / down / left / right keys provided on the remote controller, for example. Select.

  The person information construction means 9f constructs personal information (profile, etc.) related to the person selected by the person selection means 9e, so that various information about the constituent elements (birth date, hobbies, etc.) of the personal information can be obtained by searching the Internet. 15 and the person information is constructed based on the acquired information. The person information construction unit 9f stores the constructed person information in the person information cache area 7b. Further, the person information construction unit 9f acquires the person information from the person information cache area 7b when the person information related to the person selected from the person list displayed on the display unit 13 exists in the person information cache area 7b. To do.

  As a component acquisition method, for example, a Web API provided by a search site is used, and a person name, date of birth, and the like are transmitted to the search site as search keywords and a search result is received. The search result includes a plurality of URLs including search keyword information, and the date of birth can be acquired by analyzing the received data from the URL.

  Furthermore, the reliability is estimated for a plurality of URLs obtained as a search result, and the received data is analyzed in order from the URL with the highest reliability. As a method of estimating the reliability, for example, among the plurality of URLs obtained as a search result, the URL description order may be the reliability, and the URL described first may be the highest reliability. Alternatively, a reliability scale may be set, the URL may be analyzed to determine whether the scale is satisfied, and the total score determined for each scale may be used as the reliability of the URL. As a scale, for example, a domain name (com or the like), presence or absence of a search function, the number of external links, and the like can be used.

  The person information display unit 9g notifies the OSD processing unit 6 of the person information constructed by the person information construction unit 9f and displays the person information on the display unit 13.

  FIG. 2 is a flowchart showing a person list display processing procedure of the digital broadcast receiving apparatus of the present embodiment. FIG. 3 is an explanatory diagram showing an example of a video display screen in the display unit of the digital broadcast receiving apparatus of the present embodiment. FIG. 4 is an explanatory diagram showing the state of the RAM that stores the extracted face image data in the digital broadcast receiving apparatus of the present embodiment. FIG. 5 is an explanatory diagram showing an example of the configuration of a person list in the digital broadcast receiving apparatus according to the present embodiment. FIG. 6 is an explanatory diagram showing an example of a display screen for displaying a person list in the digital broadcast receiving apparatus of the present embodiment. The person list display process will be described below with reference to FIGS.

  Based on FIG. 2, the operation | movement of the person list display process of the digital broadcast receiver of this Embodiment is demonstrated. When the power of the digital broadcast receiving apparatus is turned on, the application program of the digital broadcast receiving apparatus is activated, and the control unit 9 receives the digital broadcast signal and displays the video of the selected channel program on the display unit 13 (step). 100). In the normal video display, for example, as shown in FIG. 3, the video is displayed in the video display area 501 of the display unit 13 of the digital broadcast receiving device 500.

  When the video is displayed on the display unit 13, the control unit 9 determines whether or not the person information display start mode is started (step 101). In the person information display start mode, for example, the user selects “start” or “stop” by remote control operation.

  If the person information display start mode is stopped in step 101, normal video display is continued. When the person information display start mode is started in step 101, the face image data automatic extracting means 9a extracts the face image data of all the persons included in the video displayed on the display unit 13, and is shown in FIG. As shown, the face image ID is assigned to each face image data and stored in the RAM 8 (step 102).

  When all the face image data is extracted, the person specifying means 9b acquires the program information of the selected program, and acquires the name of the character included in the program information (step 103).

  Next, the person specifying means 9b collates the face image data extracted in step 102 with the reference face image data of the person registered in the person database 7a or the person database 14a, and the reference face image data having a high similarity rate. Are extracted, and the name of the reference face image data whose name matches the name of the person in the extracted reference face image data is identified as the person of the face image data (step 104). The person database 7a registered in the flash ROM 7 is previously stored in the digital broadcast receiving apparatus.

  When the person of the face image data is specified, the person list construction unit 9c determines whether or not the person is already registered in the person list (step 105). For example, as shown in FIG. 5, the person list is a list in which the person name and the face image data of the person are associated with each other by associating the person name with the face image ID. When this step 105 is performed for the first time, nothing is registered in the person list. As will be described later, when the program is switched, this person list is deleted and nothing is registered.

  If it is already registered in the person list in step 105, the process returns to step 104 to specify the person of the face image data for which no person is specified.

  If it is not registered in the person list in step 105, the face image ID of the face image data specifying the person and the name of the person are registered in the person list (step 106).

  When the person list is newly constructed in this way, the person list display unit 9d notifies the OSD processing unit 6 of the name of the person registered in the person list and the face image data of the person, thereby displaying the display unit. The person list is displayed at 13 (step 107). For example, as shown in FIG. 6, the person list is displayed in a person list display area 502 provided below the reduced video display area 501. Further, the person selecting means 9e displays a cursor 503 for selecting a person who wants to know detailed information superimposed on the person display list. The default position of the cursor 503 is assumed to be the person registered in the person list first.

  When the person list is displayed, the control unit 9 determines whether or not a person has been identified for all the face image data stored in the RAM 8 (step 108).

If no person has been specified for all the face image data, the process returns to step 104 to specify the person of the face image data for which no person has been specified.
If a person can be identified for all the face image data, it waits for a certain period of time to elapse (step 109).
When the predetermined time has elapsed, the process returns to step 102, and face image data of all persons included in the video displayed on the display unit 13 is extracted again.

  FIG. 7 is a flowchart showing a person information display processing procedure of the digital broadcast receiving apparatus according to the present embodiment. FIG. 8 is an explanatory diagram showing an example of the configuration of the person information. FIG. 9 is an explanatory diagram illustrating an example of a display screen for displaying personal information. Hereinafter, the personal information display process will be described with reference to FIGS.

  Based on FIG. 7, the operation | movement of the person information display process of the digital broadcast receiver of this Embodiment is demonstrated. A person who wants to know detailed information is selected from the person list displayed on the display unit 13 by the user's operation of the cursor 503 (step 200). Since the default position of the cursor 503 is the person first registered in the person list, for example, the person information display processing of the person operates first.

When a person who wants to know detailed information is selected, the person information construction unit 9f determines whether or not the person information related to the selected person exists in the person information cache area 7b (step 201).
If the person information exists in the person information cache area 7b, the person information is acquired from the person information cache area 7b (step 202), and the process proceeds to step 209.

  If the person information does not exist in the person information cache area 7b, the constituent elements of the person information are extracted as search keywords (step 203). For example, in the case of the person information as shown in FIG. 8, the constituent elements of the person information are occupation, gender, birthplace, date of birth, age, favorite food, hobby, appearance drama, and appearance movie.

  The person information construction unit 9f searches the extracted keyword on the Internet (step 204), estimates the reliability of a plurality of URLs obtained as a search result, and relates to the constituent elements in order from the URL with the highest reliability. Information is acquired (step 205).

  Next, when the person information construction unit 9f obtains information on these constituent elements, it determines whether or not information on all the constituent elements has been obtained (step 206).

  Furthermore, the person information construction unit 9f returns to step 204 and continues the search if information on all the constituent elements has not been acquired.

  Further, if the information about all the constituent elements can be acquired, the person information construction unit 9f constructs the person information based on the acquired information (step 207). For example, the personal information is as shown in FIG.

  Further, the person information construction unit 9f stores the constructed person information in the person information cache area 7b (step 208).

  When the person information is constructed by the person information construction unit 9f, the person information display unit 9g notifies the OSD processing unit 6 of the person information and displays the person information on the display unit 13 (step 209). For example, the person information is displayed in a person information display area 504 provided on the right side of the video display area 501 and the person list display area 502 as shown in FIG.

  Although not described in the flowchart shown in FIG. 7, at the timing when the program being viewed by the user is switched, the person list construction unit 9c deletes all registration information of the person list, and the person information construction unit 9f All the person information stored in the person information cache area 7b is deleted.

  Further, in the present embodiment, the constituent elements of the person information have been described using only text information such as the date of birth and hobbies as an example. In this case, for example, as shown in FIG. 10, image display areas 504a and 504b and moving image display areas 504c and 504d are provided in the person information display area 504 to display images and moving images that are constituent elements of the person information. be able to.

  FIG. 11 is a flowchart showing search result analysis processing in the person information display processing of the digital broadcast receiving apparatus of the present embodiment. FIG. 12 is an explanatory diagram of an example of a URL reliability list. The search result analysis process will be described below with reference to FIGS. 11 and 12.

  FIG. 11 is a flowchart illustrating the search result analysis process shown in step 205 in the person information display process described with reference to FIG. 7 in more detail. When starting the analysis of the search result (step 600), the person information construction unit 9f extracts the URL obtained as the search result (step 601).

  Next, the person information construction unit 9f estimates reliability for each extracted URL (step 602), and creates a reliability list. For example, as shown in FIG. 12, the reliability list is a list in which reliability and URL are associated with each other, and includes a reliability column and a URL column, and a reception column indicating whether data is received from the URL. Composed. The initial value of the reception column is 0 indicating that no data has been received.

  When the estimation of the reliability is completed, the person information construction unit 9f extracts the URL with the highest reliability from the URLs in which the reception column of the reliability list is 0, and after receiving data from the URL, The reception column associated with the URL in the reliability list is set to 1 (step 603).

  When the person information construction unit 9f receives the data, the person information construction unit 9f performs data analysis and acquires information on the constituent elements (step 604).

  The person information construction unit 9f determines whether or not information on the constituent elements has been acquired as a result of the data analysis (step 605).

  The person information construction unit 9f returns to step 603 if the information cannot be acquired in step 605. If the information can be acquired in step 605, the person information construction unit 9f ends the analysis of the search result (step 606).

  As described above, the digital broadcast receiving apparatus according to the present embodiment automatically extracts face image data of all persons included in the video being viewed, and extracts the face images extracted by referring to the person database. The person in the data is identified, the name of the identified person and the face image data of the person are displayed in a list, and the user can select a person who wants to know more detailed information from the listed persons by operating the cursor. it can. Therefore, when the user wants to know detailed information about the person included in the video being viewed while the user is watching the video content, the user can equip the remote control even for the video where the person is moving. Since the person can be easily selected by simply pressing the up / down / left / right key several times, the troublesome operation when selecting the person can be reduced and the person can be surely selected.

  In addition, detailed information about the person selected by the user can be obtained by searching the Internet, and the person information constructed based on the latest information obtained can be displayed, so that the user can always obtain useful information. This can give the user a sense of satisfaction.

  In addition, it is possible to extract the face image data of all the persons included in the video that the user is watching every time a certain time elapses, and display the person list following the appearance of the characters, Since it is possible to display a list including persons appearing in past video scenes, the user can select all persons appearing in the program being viewed.

  In addition, when specifying a person of face image data, it is possible to perform face image data matching and person name matching, so that it is possible to improve the person identification accuracy.

  In addition, since it is possible to prevent double registration of persons already registered in the person list, the memory usage is reduced, and the same person is not displayed twice in the person list. Can be eliminated.

  In addition, since the registration information of the person list can be deleted when the program is switched, a person who is not related to the video being viewed by the user is not displayed in the person list, and the user is not uncomfortable. be able to.

  Also, by constructing person information based on information obtained from a highly reliable server, users can always obtain highly reliable and useful information, which can give satisfaction to the user. .

  In addition, by caching the constructed person information, the display start time of the person information can be shortened.
