Description

  The present invention relates to a technique for determining a broadcast program to be recommended according to a user's preference level.

  Since the number of broadcast contents has increased dramatically due to the digitalization of broadcast, it has been pointed out that there is a problem that it is difficult for a user to search for broadcast contents that the user wants to view.

  Many methods for solving this problem have been proposed. In particular, the user can specify a favorite genre in advance, or automatically obtain and analyze the genre of the broadcast content viewed by the user, and determine the user's favorite genre. There are many methods.

  In addition, recent digital broadcast receivers such as TVs and DVD recorders have not only broadcast reception functions but also built-in storage media such as HDDs, including still images such as photos taken by users and videos such as videos, It has functions to store and view various contents.

  These contents photographed by the user also include user preference information. For example, as disclosed in Patent Document 1, there is a technique for recommending a program using these contents.

In addition, digital broadcasting can be received even by a car navigation device mounted on the vehicle. For example, as disclosed in Patent Document 2, there is a technique for recommending a program by using a user's movement position information by a GPS (Global Positioning System) mounted on a car navigation system.

  The embodiment described below is an example as means for realizing the present invention, and should be appropriately modified or changed according to the configuration and various conditions of the apparatus to which the present invention is applied. It is not limited to the embodiment.

[First Embodiment]
FIG. 1 is a block diagram showing a schematic configuration of a broadcast receiving apparatus according to the first embodiment of the present invention.

  In FIG. 1, the broadcast receiving apparatus of the present invention is realized by, for example, a digital broadcast television receiving apparatus (hereinafter referred to as DTV). The DTV 101 includes a broadcast content processing unit 104, a broadcast content analysis unit 105, a non-broadcast content processing unit 107, a non-broadcast content analysis unit 108, a broadcast / non-broadcast content storage unit, a viewing history storage unit 110, a preference level determination unit 111, a display The unit 112 is provided.

  The remote control 102 can remotely control the DTV 101 by infrared communication or the like, and can notify the DTV 101 of a user operation. The broadcast wave antenna 103 receives a digital broadcast wave and outputs the received digital broadcast wave to the broadcast content processing unit 104.

  The broadcast content processing unit 104 separates / decodes / combines / outputs a digital broadcast wave input from the broadcast wave antenna 103.

  The broadcast content analysis unit 105 analyzes SI (Service Information: Program Information) / PSI (Program Specific Information: Program Specific Information) included in the digital broadcast wave. Broadcast content analysis unit 105 outputs the analysis result to broadcast / non-broadcast content storage unit 109.

  The external device 106 outputs non-broadcast content data such as a still image or a moving image taken by the user to the non-broadcast content processing unit 107.

  The non-broadcast content processing unit 107 performs separation / decoding / composition / output of non-broadcast content data input from the external device 106.

  The non-broadcast content analysis unit 108 analyzes the shooting information of the content included in the non-broadcast content, and stores the analysis result in the broadcast / non-broadcast content storage unit 109.

  The broadcast / non-broadcast content storage unit 109 stores broadcast content information input from the broadcast content analysis unit 105 and non-broadcast content information input from the non-broadcast content analysis unit 108.

  The viewing history accumulation unit 110 accumulates the history of broadcast content and non-broadcast content viewed by the user in the past.

  The preference level determination unit 111 creates recommended program information according to the user's preference level from the viewing history information stored in the viewing history storage unit 110. Then, the preference level determination unit 111 determines the recommendation level of the broadcast program so as to match the user's preference level from the broadcast content information and the non-broadcast content information stored in the broadcast / non-broadcast content storage unit 109. A display unit 112 controls display of video and audio, and displays a program list such as EPG to the user.

  Broadcast content received from the broadcast wave antenna 103 is processed by the broadcast content processing unit 104 of the DTV 101. Specifically, MPEG2 TransportStream demultiplexing, MPEG2 video, audio decoding, AV synchronization processing, time management, data broadcasting processing, and output processing. In addition, since the conventionally well-known method is employable about the detailed process in the broadcast content process part 104, description here is abbreviate | omitted.

  The video / audio processed by the broadcast content processing unit 104 is output to a monitor or a speaker (not shown) through the display unit 112.

  At the same time, the broadcast content processing unit 104 supplies broadcast content information such as SI / PSI included in the broadcast wave to the broadcast content analysis unit 105.

  Here, the SI / PSI information included in the broadcast wave is composed of a PAT (Program Association Table), a PMT (Program Map Table), and the like. Furthermore, it is composed of an EIT (Event Information Table), NIT (Network Information Table), and the like.

  Among these, the contents related to the recommended program include the service ID, event ID, program start time, broadcast duration, program name, description of program contents, performer, screenwriter, moderator in EIT. The name of the person such as the person, the genre and characteristics of the program are described. Here, the genre of the broadcast program is defined by a large genre such as "report", "sports", "drama", "movie", "variety", "education", etc., and a medium genre that subdivides the large genre. . For example, “soccer”, “baseball”, “Olympic” and the like are defined as medium genres obtained by subdividing the large genre “sports”. In the series descriptor, information on a series program, a rebroadcast program, and the like is described.

  The broadcast content analysis unit 105 analyzes various broadcast content information such as the program name, broadcast time, and genre of the broadcast content from the above-described SI / PSI information, and accumulates it in the broadcast / non-broadcast content accumulation unit 109.

  In addition, the broadcast content analysis unit 105 adds 1 to the viewing number counter stored in the viewing history storage unit 110 for the genre of the broadcast content determined to be viewed by the viewer.

  FIG. 2 exemplifies the viewing count management data stored in the viewing history storage unit 110.

  As shown in FIG. 2, the viewing history storage unit 110 manages the number of times of viewing for each genre.

  Non-broadcast content input from the external device 106 is acquired and processed by the non-broadcast content processing unit 107. Here, as the external device 106 connected to the DTV 101, various devices can be assumed.

  Specific examples include devices such as a digital still camera, a digital video camera, and an SD card. These devices are connected via an I / F (interface) such as EtherNet (registered trademark), USB, card reader, etc., and data of non-broadcast content such as still images and videos taken by the user is not broadcast. The data is output to the content processing unit 107.

  The non-broadcast content processing unit 107 performs a digital video moving image reproduction process, a digital camera still image reproduction process, and the like according to the external device 106. In addition, regarding various processing of these non-broadcast contents, a conventionally known method can be adopted, and thus description thereof is omitted here.

The video / audio processed by the non-broadcast content processing unit 107 is output to a monitor or a speaker (not shown) through the display unit 112.
At the same time, the non-broadcast content processing unit 107 supplies the non-broadcast content analysis unit 108 with Exif information, which is shooting information of a still image shot with a digital camera, among the non-broadcast content. Also, VIDEO_TS., Which is shooting information of a movie shot by a DVD video camera. The IFO file information is supplied to the non-broadcast content analysis unit 108. Exif is an abbreviation for Exchangeable image file format for digital still camera.

  Here, the Exif information included in the still image data includes the shooting date and time, the manufacturer name of the shooting device, the shooting model name, the GPS data of the shooting position, and the like. In addition, VIDEO_TS. As for IFO information, the same type of information as still image data can be acquired.

  The non-broadcast content analysis unit 108 is configured to use the Exif or VIDEO_TS. Information such as the shooting date and time of the non-broadcast content, the manufacturer name of the shooting device, the model name of the camera, and the GPS data of the shooting position included in the IFO information is stored in the broadcast / non-broadcast content storage unit 109.

  The viewing history storage unit 110 stores the number of times of viewing per genre used in the broadcast content for the broadcast content. When the user requests the recommendation level of the broadcast content by operating the remote controller 102, the preference level determination unit 111 acquires the viewing frequency information for each genre stored in the viewing history storage unit 110, and the user's preference level A high genre is determined.

  Then, a program included in the same genre is searched from future broadcast programs stored in the broadcast / non-broadcast content storage unit 109 and displayed on the display unit 112 in a state that can be recognized by the user. In this way, the recommended program determination process according to the user's preference level is executed.

  FIG. 3 illustrates an EPG screen in which the recommended program determination result according to the first embodiment is reflected. In the EPG screen of FIG. 3, the recommendation level is represented by an asterisk for each displayed program, and the greater the number of asterisks, the higher the recommendation level. In FIG. 3, a “photo icon” indicating that there is a still image taken at a location related to the displayed program is displayed.

  In the first embodiment, when newly determining a recommended program, the shooting position information of a non-broadcast content such as a still image or video shot by a user is used to relate to the shooting position for each program that is a recommended candidate. The recommendation level of the program is increased or the recommendation level of the program not related to the opposite is increased.

  FIG. 4 is a flowchart showing recommended program determination processing according to the first embodiment of the present invention.

  Hereinafter, with reference to FIG. 1 and FIG. 4, the recommended program determination process of the present embodiment will be described.

  Here, it is assumed that broadcast program information and shooting information as non-broadcast content are already stored in the broadcast / non-broadcast content storage unit 109.

  First, the user operates the remote controller 102, an EPG screen is generated and output by the broadcast content processing unit 104 according to the operation instruction, and the EPG screen shown in FIG. 3 is displayed on the display unit 112.

  Here, the preference level determination unit 111 executes a recommended program determination process in order to display the recommendation level for each program on the EPG screen.

  That is, in S401, the preference level determination unit 111 performs a recommended program determination process using the viewing frequency information for each genre stored in the viewing history storage unit 110, and adds a recommendation level and the like based on the determination result. Create recommended program information. For the determination processing here, a conventionally known method can be adopted. For example, in the case of a user who often views travel programs and news programs, the news program and travel program are used as recommended programs.

Next, in S402, the preference level determination unit 111 performs a recommendation level determination process using the non-broadcast content information for the recommended program created in S401 .

  FIG. 5 is a flowchart illustrating recommendation program recommendation level determination processing according to the first embodiment.

  In FIG. 5, in S501, the preference level determination unit 111 acquires program content information of a recommended program from the broadcast / non-broadcast content storage unit 109, analyzes the program content information by the broadcast content analysis unit 105, and positions related to the recommended program. Detect information. Here, for example, in the EPG screen of FIG. 3, character string information such as “Kawasaki”, “Hokkaido”, “Hawaii” is extracted.

  In S502, the preference level determination unit 111 acquires latitude and longitude range information from the position information detected in S501 from the table information and map data held by the preference level determination unit 111.

  FIG. 6 illustrates a position information classification table according to the first embodiment.

  As shown in FIG. 6, the preference level determination unit 111 holds each position information divided into a large classification and a small classification. In step S502, the position information detected in step S501 is specified as position information in the large classification or position information in the small classification. In addition, the preference level determination unit 111 holds map data, and acquires latitude / longitude information from the position information of the major classification and the minor classification from the map data. Here, latitude / longitude range information is acquired from map data from position information such as “Kanto”. As for details of this method, since a conventionally known method can be adopted, description thereof is omitted here.

  In S503, the preference level determination unit 111 compares the latitude / longitude range information acquired in S502 with shooting position information such as a still image as non-broadcast content, and performs shooting within the latitude / longitude range. It is determined whether there are still images that have been taken.

  In S504, the preference level determination unit 111 acquires genre information of a broadcast program to be recommended.

  In S505, the preference level determination unit 111 determines whether the genre of the recommended broadcast program is, for example, a travel program. If the recommended broadcast program is a travel program, the process advances to step S506, and the preference level determination unit 111 displays the position information of the recommended travel program and the shooting position information of a still image as non-broadcast content. It is determined whether the classification table shown in FIG. If it is determined in S506 that it matches the small category, it can be determined that there is a high possibility that shooting has already been performed at a position related to the travel program to be recommended and that location has been reached. Therefore, it can be determined that the user's preference for this place is low. Therefore, when the small classification is matched in S506, the preference level determination unit 111 performs a process of lowering the recommendation level of the recommended program in S507. For example, in the EPG screen of FIG. 3, when a still image taken at “Izu”, which is the location of the travel program 2, is non-broadcast content, the recommendation level is set low and the recommendation level is set as one star. . In FIG. 3, a “photo icon” indicating that there is non-broadcast content shot at the location of the travel program 2 is displayed to notify the user.

  On the other hand, if it is determined in S506 that the classification does not match the subcategory, in S508, the preference determination unit 111 determines that the location information of the recommended travel program and the location information of the non-broadcast content are as shown in FIG. It is determined whether the classification table matches the major classification.

  If it is determined in step S508 that the broadcast program matches the major category, the location of the recommended broadcast program roughly matches the region in which the user is interested in the major category, but the minor category is a specific category. I have never been to a particular place. Therefore, it can be determined that the area has interest but has not yet been visited. Accordingly, if the major classification is matched in S508, the preference level determination unit 111 performs a process of increasing the recommendation level of the recommended program in S509. For example, on the EPG screen of FIG. 3, when a still image taken at “Kawasaki”, the location of the news program, is non-broadcast content, the recommendation level is increased and set as the recommendation level of three stars. Similarly, in FIG. 3, although there is non-broadcast content shot at “overseas” roughly related to the location of the travel program 3, non-broadcast shot at a specific location “Hawaii” When there is no content, the recommendation level is increased and set as the recommendation level of three stars.

  On the other hand, if it is determined in S508 that it does not match the major classification, that is, if there is no non-broadcast content related to the broadcast program to be recommended, this processing ends and the recommendation created in S401 of FIG. Apply program information.

  Further, if it is determined in S505 that the genre of the recommended broadcast program is not a travel program, the process proceeds to S510.

  In S510, the preference level determination unit 111 determines whether the position information of the program and the position information of the non-broadcast content for the broadcast program of the genre other than the recommended travel program are the major classification or Judge whether it matches the small classification.

  If it is determined in S510 that the major category or the minor category is matched, in S511, the recommendation level is increased for the recommended broadcast program. For example, in the EPG screen of FIG. 3, it is determined that the user has taken a photograph or the like at “Kawasaki”, which is location information related to the news program, and the user's interest is high. Processing to increase the degree is performed.

  According to the first embodiment, when determining a recommended program, the position information of a non-broadcast content such as a still image or a video shot by the user according to the genre (type) of the broadcast program to be recommended And the recommendation level is determined using different determination conditions. This makes it possible to determine a recommended program that more matches the user's preference level.

  That is, unlike the conventional case, for example, even when the same travel program is used as a recommended program, the degree of recommendation is reduced for a program related to a place where the user has actually performed. Moreover, although it has been performed in a rough classification and is considered a place of high interest, a program related to a place that has not been visited yet has a high recommendation level. In this way, it is possible to determine a recommended program that matches the user's preference level in more detail.

  In the first embodiment, the location information as the non-broadcast content is changed for the travel program and other programs. However, the present invention is not limited to this, and depending on the type of the broadcast program It is also possible to change the position information used for the determination.

  Further, in the first embodiment, it is determined based on the presence / absence of non-broadcast content, whether or not it has been performed is determined. The determination may be made based on “when the ratio of the number of matched sheets / the total number of sheets is equal to or greater than a certain value”.

[Second Embodiment]
Next, as a second embodiment, a method for determining a recommended program that matches a user's shooting conditions using shooting information at the time of shooting a still image as non-broadcast content will be described.

  Here, the apparatus configuration for realizing the second embodiment is the same as the configuration shown in FIG.

  FIG. 7 is a flowchart showing recommended program determination processing according to the second embodiment of the present invention. FIG. 8 is a diagram illustrating an imaging model information table according to the second embodiment.

  Hereinafter, the recommended program determination process of the second embodiment will be described with reference to FIGS.

  Here, it is assumed that broadcast program information and shooting information of non-broadcast content are already stored in the broadcast / non-broadcast content storage unit 109.

  First, the remote controller 102 is operated by the user, an EPG screen is generated and output by the broadcast content processing unit 104 in accordance with the operation instruction, and the EPG screen is displayed on the display unit 112.

  At this time, the preference level determination unit 111 executes the recommended program determination process shown in FIG. 7 in order to display the recommendation level of the program on the EPG screen.

  In FIG. 7, in S701, the preference level determination unit 111 determines whether the broadcast / non-broadcast content storage unit 109 has a predetermined number of still images or more. Here, for example, when 100 or more still images are accumulated, it can be determined that still image shooting is being performed or that the user is interested in shooting, and therefore, the processing from S702 onward is executed. If the number of still images is less than the predetermined number in S701, the process ends.

  Next, in S702, the preference level determination unit 111 acquires the shooting model name or manufacturer name from the shooting information stored in the broadcast / non-broadcast content storage unit 109, and is included in the shooting model information table shown in FIG. Compare with model name or manufacturer name. If it is determined that shooting is being performed by the mobile phone, the user determines that the shooting method is not so particular and the necessity of recommending an explanation program for the shooting method is low, and the process ends.

  On the other hand, if it is determined in S702 that shooting is being performed by a device other than a mobile phone, in S703, the preference level determination unit 111 is shooting with a single-lens reflex digital camera as in S702. judge.

  In S703, when shooting is performed with a single-lens reflex type digital camera, in S704, the preference level determination unit 111 sets the explanation program for the shooting method of the single-lens reflex camera as a recommended program.

  As a method for determining the recommended program, a conventionally known method can be adopted. For example, “Introductory! Digital SLR photography course” that matches broadcast keyword information by searching for “single-lens reflex” and “shooting” keywords. It is possible to make a program a recommended program.

  In S703, if shooting is not performed with a single-lens reflex type digital camera, in S705, the preference level determination unit 111 captures a digital camera other than the single-lens reflex camera (for example, a compact digital camera). The explanation program is a recommended program.

  As a method for determining the recommended program, a conventionally known method can be adopted. For example, it is possible to search for broadcast program information using the keyword “photographing” and match the program “Simple Digital Camera Shooting” as a recommended program. is there.

  According to the second embodiment, the number of images taken, the name of the shooting model, the name of the model manufacturer, etc. are used as the non-broadcast content information, and whether the user is interested in shooting or what model is used for shooting. Judge whether it is. Thereby, it is possible to determine a recommended program more suitable for the user's preference level. That is, unlike the conventional case, it is possible to determine a recommended program with high accuracy with respect to the user's preference by taking into consideration the shooting situation such as the number of shots and the shooting model.

Here, the program explaining the shooting method is determined by using shooting mode information such as “fireworks” and “night view” among the still image information stored in the broadcast / non-broadcast content storage unit 109. If there is a still image shot in the fireworks mode, the degree of recommendation of the program “Introduction to Digital Camera Shooting—Fireworks Shooting Method” is increased. Also, if there are still images shot in the night view mode, the recommendation level of the program “Introduction to Digital Camera Shooting-Let's Shoot Beautiful Night Views” is increased. This allows determining the recommendation number set that matches the finer preference of the user.

  In the second embodiment, a still image has been described as an example. However, the present invention is not necessarily limited to a still image, and similar processing can be applied to a moving image.

[Third Embodiment]
Next, as a third embodiment, a method of determining a recommended program related to a shooting object that has been shot more by the user using shooting object information as non-broadcast content will be described.

  Here, the configuration of the apparatus for realizing the third embodiment is the same as the configuration shown in FIG.

  FIG. 9 is a flowchart showing recommended program determination processing according to the third embodiment of the present invention. FIG. 10 is a diagram illustrating a photographing object information database according to the third embodiment.

  Hereinafter, the recommended program determination process of the third embodiment will be described with reference to FIG. 1, FIG. 9, and FIG.

  Here, it is assumed that broadcast program information and shooting information of non-broadcast content are already stored in the broadcast / non-broadcast content storage unit 109.

  First, the remote controller 102 is operated by the user, an EPG screen is generated and output by the broadcast content processing unit 104 in accordance with the operation instruction, and the EPG screen is displayed on the display unit 112.

  At this time, the preference level determination unit 111 executes the recommended program determination process shown in FIG. 9 in order to display the recommendation level of the program on the EPG screen.

  In FIG. 9, in S901, the preference level determination unit 111 acquires photographed image data from the broadcast / non-broadcast content storage unit 109, and via the non-broadcast content analysis unit 108, the main photographing target included in the photographed image data. Get material information. Here, object identification and face identification of the captured image data are performed using a conventionally known method, and object information such as “ramen” shown in FIG. 10 or a rough person such as “infant” or “male teenager” is shown. Get classification information.

  In S901, it is determined whether the main object to be photographed was accidentally photographed on only one sheet or was photographed according to the user's interest. For this reason, when a certain number of images are taken or when “the number of non-broadcast contents in which the same object is photographed / the total number of non-broadcast contents” is a certain ratio or more, the photographing object information can be acquired.

  In S902, the preference level determination unit 111 determines whether the shooting target information of the non-broadcast content has been detected as a result of the search in S901. If it is determined that it has not been detected, the process ends. Also, as a result of the search in S901, if it is determined that the shooting target information of the non-broadcast content can be detected, in S903, the preference level determination unit 111 shows a program related to the shooting target information acquired in S901. Is determined as a recommended program.

  Here, for example, when “ramen” is searched as the photographing object information in S901, a program including the character string “ramen” is set as a recommended program.

  For example, when “female 30s or older” is searched as shooting object information, a program such as “professional information for housewives” including the character string “housewife” is set as a recommended program.

  According to the third embodiment, a shooting target that has been shot with interest by a user, which is present in shot image data as non-broadcast content, is identified, and a program related to the shooting target is defined as a recommended program. It becomes possible to do.

  In other words, unlike a conventional case, when a certain number or more of image data obtained by shooting a specific object such as “ramen” is accumulated as non-broadcast content, a program related to the object is set as a recommended program without user designation. Is possible.
