The video distribution service is basically a service in which the video distribution server 10 distributes video to the display device 12 (outputs video information) and causes the display device 12 to display the video. As the video distribution method, any of the existing distribution methods such as streaming reproduction or a method of causing the display device 12 to download the file once and opening the downloaded file for reproduction can be applied.
In the video distribution service, the information processing unit 30b of the video distribution server 10 matches the search condition from the image information provided by the image information providing server 18 by a predetermined search formula (search condition) using a search key. Search and acquire (download) the image information that has been obtained. That is, the information processing unit 30b searches the image information existing innumerably on the Internet 11 for a search condition that matches the search condition.
As is well known, the image information normally stores metadata that is supposed to be used as a tag when searching. For example, a comment segment formed in a predetermined area of a JPEG file stores metadata that can be used as a tag when searching. For example, in an MPEG-7 file, metadata can be described in XML. It is. Then, the information processing unit 30b uses the function of an existing search engine that performs a search using the metadata of the image information to search for and acquire image information that matches the search condition. Note that the function of searching for image information may be implemented in the video distribution server 10 itself, or the function of an external server may be used.

Similarly, the information processing unit 30b searches the sentence information provided by the sentence information providing server 19 for the sentence information that matches the search condition by using a search expression (search condition) using the search key, and acquires it. Yes (download). In other words, the information processing unit 30b searches the text information existing innumerably on the Internet 11 from those that can be acquired and that matches the search condition.

Therefore, the information processing unit 30b searches for text information that matches the search condition by using a function of a predetermined search engine that performs a search using the tag. In addition, for example, when the text information is information related to text described on a company / personal homepage, the information processing unit 30b functions as a predetermined search engine that performs a search using index information as metadata. Is used to search for text information that matches the search conditions.
Furthermore, the information processing unit 30b searches for and acquires voice information that matches the search condition from the voice information provided by the voice information providing server 20 using a search formula (search condition) using a search key ( to download). In other words, the information processing unit 30b searches for audio information that can be acquired from a myriad of audio information on the Internet 11 and that matches the search condition. As is well known, since the music information stores metadata that is assumed to be used as a tag when searching (for example, metadata of an MP3 file), the information processing unit 30b stores the metadata. Search and acquire image information that matches the search conditions using the function of an existing search engine that uses and searches.

After searching for each of image information, sentence information, and audio information as described above, the information processing unit 30b combines an image (moving image, still image) based on the image information and a sentence based on the sentence information. Video information to be displayed. The video information is, for example, an image file used for streaming playback when displaying video on the display device 12 by streaming playback.
FIG. 3 is a diagram illustrating an example of an image displayed on the display panel 41a of the display device 12 based on the image information.
As shown in FIG. 3, in the video based on the video information, an image G (moving image, still image) based on the image information is displayed on the entire area of the display panel 41a, and a text B based on the text information is displayed in a predetermined area below. Is displayed as a string. In this way, the information processing unit 30b displays a video in which an image based on image information and a text based on text information are combined in a manner as shown in FIG. 3 based on the image information and text information. Generate video information. The video in FIG. 3 is merely an example, and the position of the text based on the text information is not limited to the position shown in FIG. Also good. The video distribution server 10 is provided with a function of combining image information and text information in a predetermined manner by performing predetermined image processing on the image information. By this function, video information is generated based on image information and text information.
Next, the information processing unit 30b outputs the generated video information to the display device 12 in accordance with a predetermined protocol, outputs audio information to the display device 12, and displays the video indicated by the video information on the display panel 41a. At the same time, sound is output based on the sound information. “Output the video information to the display device 12 to display the video” means, for example, in the case of streaming playback, the image file relating to the generated video information is transferred and played back in a predetermined procedure. For example, in the case of a method of displaying a video by downloading a file, it means that after downloading an image file related to video information, the image file is opened and reproduced.

The information processing unit 30b continuously displays video on the display device 12 by continuously generating and outputting the video information as described above. That is, since there are an infinite number of image information and text information on the Internet 11, it is assumed that there are a considerable number of image information and text information that match the search condition. Then, the information processing section 30b sequentially generates video information according to a predetermined priority order based on the searched and collected considerable number of image information and text information, and displays the video.
As described above, in the present embodiment, the video distribution server 10 does not repeatedly display the same video according to a predetermined rule based on the image file prepared in advance, Then, text information is searched and collected, and video information is generated based on the information in order and displayed. For this reason, it is possible not to repeatedly display the same image but to display different images at random, and to improve user satisfaction without getting tired of the user.

Further, the information processing unit 30b searches for and acquires image information and text information on the Internet 11 based on the search condition, and “combines these pieces of information based on the acquired image information and text information. The video information to be displayed is generated and the video information is output to the display device 12. In this way, by searching for image information and text information based on search conditions, image information and text information are not collected randomly, but have some uniformity or relevance. Can be properly searched and collected. And by appropriately searching and displaying the collected image information and sentence information in combination, while appealing to the intuitive sensibility of the user by the image (video, still image) displayed based on the image information, The text displayed based on the text information can stimulate the logical thinking of the user, and it is possible to display a video that appeals to the user's sensibility in a multifaceted and effective manner. It is possible to display an image that improves user satisfaction.
In particular, according to the above configuration, the image information and the text information are independently searched and collected, and the video information is generated by combining these information. Therefore, the image based on the image information and the text information are used. Various combinations with sentences can be provided as images, and this does not bore users. Furthermore, a random combination of images and sentences appeals to the user's sensibility, which may cause an unexpected and unexpected synergistic effect. In this respect, it is possible to provide a video with high entertainment properties.

By the way, as described above, the display device 12 is assumed to be installed in various places such as a coffee shop, a restaurant such as a bar, a waiting room of a financial institution, and a shared space of an office building. The atmosphere of the space in which the display device 12 is installed, the number of humans present in the space, etc. vary depending on the time zone, weather, and other factors, and are not constant. That is, the environment of the display device 12 changes due to various factors. Then, if the video displayed on the display device 12 can be adapted to the environment of the display device 12, the video displayed on the display device 12 and the surrounding atmosphere will match, without giving the user a sense of incongruity, User comfort can be improved and satisfaction can be improved.
Based on this, the video distribution server 10 according to the present embodiment performs the following operations, so that the video distribution server 10 can be appropriately adapted to the environment of the display device 12 according to the location where the display device 12 is provided and other events. The correct video.

FIG. 4 is a flowchart of operations performed when the video distribution server 10 provides a video distribution service. The process shown in the flowchart of FIG. 4 is to construct an appropriate search condition according to the environment of the display device 12, more specifically, a search used when searching for image information, text information, and audio information. This process is aimed at appropriately selecting keys. The process shown in the flowchart of FIG. 4 is performed at a predetermined timing set in advance, for example, every hour.
Referring to FIG. 4, the environment information acquisition unit 30a of the control unit 30 of the video distribution server 10 communicates with the device-side control unit 40 of the display device 12 in accordance with a predetermined protocol, and acquires installation position information. As described above, the installation position information is information indicating the coordinates (longitude, latitude) of the position where the display device 12 is provided, and is generated by the position detection unit 43 of the display device 12 (step SA1). ).
Next, the information processing unit 30b obtains the “land pattern” of the place where the display device 12 is installed (the attribute of the place where the display device 12 is installed) based on the installation position information acquired by the environment information acquisition unit 30a. Obtain (step SA2). Hereinafter, the process of step SA2 will be described in detail.
A land pattern is a characteristic or property of an area on a map such as a downtown area, an office area, a residential area, an urban area, or a local city. In the present embodiment, a map database is stored in the storage unit 33 of the video distribution server 10, the map is divided into a plurality of areas, and information indicating a land pattern is stored in association with each area. In step SA2, the information processing unit 30b determines which area on the map the installation position of the display device 12 belongs to based on the installation position information and the map database, and associates it with the area to which it belongs. The obtained land pattern is acquired as the land pattern of the place where the display device 12 is installed.
In the present embodiment, the video distribution server 10 itself has a map database and acquires a land pattern based on the installation position information, but it may be configured to make an inquiry to an external server.

Next, the information processing unit 30b acquires the “space type” of the place where the display device 12 is installed (the attribute of the place where the display device 12 is installed) (step SA3).
The space type is a classification according to the use of the space and area in which the display device 12 is provided, such as a coffee shop, a pub, a karaoke house, a station, an office building, a classroom, and a road surface. In the map database described above, “space type” is stored in association with buildings and facilities existing on the map, and the information processing unit 30b is based on the installation position information and the map database. The building or facility where the display device 12 is installed is specified, and the space type associated with the specified building is acquired as the space type of the place where the display device 12 is installed.
Next, the information processing unit 30b refers to the first search key table K1, and specifies the first search key based on the land pattern acquired in step SA2 and the space type acquired in step SA3 (step SA4). .

FIG. 5A is a diagram schematically illustrating an example of the first search key table K1.
The first search key table K1 is a table that stores a search key in association with each combination of land pattern and space type. As shown in FIG. 5A, a search key exists for each piece of image information, text information, and audio information. In the first search key table K1, each combination of a land pattern and a space type is provided. In addition, a search key for each information is stored in association with each other. This also applies to search keys in other tables described later. Further, the first search key table K1 may be defined on a program that realizes the function of the information processing unit 30b, and is data stored in the storage unit 33 in such a manner that the program can be referred to. May be. The same applies to each table described later.
Here, depending on the combination of the land pattern and the space type, the state and atmosphere (environment) of the place where the display device 12 is provided are different, and the images matching the atmosphere of the place are also different. For example, a bar in a downtown area and a coffee shop in an office area have different atmospheres of the places, and images of customers who come to the store feel comfortable. And the 1st search key table K1 matches and memorize | stores the search key for searching the image information suitable for environment, text information, and audio | voice information for every combination of a land pattern and a space classification. The search key associated with the combination of the land pattern and the space type can be freely set by the person in charge.
In step SA4, the information processing unit 30b refers to the first search key table K1, and uses the first search key associated with the combination of the land pattern acquired in step SA2 and the space type acquired in step SA3. Identified as a search key. For example, in the example of FIG. 5A, when the land pattern is “office town” and the space type is “coffee shop”, the information processing unit 30 b uses “luxury” as the first search key for image information. “Economic news” is specified as a first search key for text information, and “low tempo” is specified as a first search key for music information.

In the present embodiment, the display device 12 includes the position detection unit 43 that detects its own position using GPS radio waves. However, the display device 12 automatically detects its own position. It may not have a function. Even in such a case, the environment information acquisition unit 30a can acquire the installation position information of the display device 12 by the following means. That is, in recent years, mobile phones and mobile terminals (external devices) having a position detection function using GPS have become widespread. Using this, the video distribution server 10 publishes a dedicated page that can be accessed from a mobile phone or the like. For example, when the operator is using the display device 12 near the display device 12, When the mobile phone is used to access the dedicated page and perform a necessary operation, the mobile phone outputs positional information of the mobile phone to the video distribution server 10. Then, the environment information acquisition unit 30a acquires the position information of the mobile phone as the installation position information of the display device 12.
In addition, a dedicated application for causing the mobile phone or the like to output the location information of the mobile phone to the video distribution server 10 via the Internet 11 is installed, and the environment information acquisition unit 30a acquires the installation location information by the function of this application. It may be configured to.
In addition, the video distribution server 10 provides a predetermined user interface to the display device 12 or a device such as a mobile phone, and the user inputs information regarding a place where the display device 12 is installed to the provided user interface. For example, the environment information acquisition unit 30a may acquire the installation position information by means including human means.

Now, after specifying a 1st search key, the environment information acquisition part 30a acquires the date information which shows the present day of the week and time (step SA5). The acquisition of the day of the week and the time is performed by, for example, an existing technology using an RTC or a CPU clock.
Next, the information processing unit 30b refers to the second search key table K2 and specifies the second search key based on the date / time information acquired in Step SA5 (Step SA6).
FIG. 5B is a diagram schematically illustrating an example of the second search key table K2.
The second search key table K2 exists for each combination of land pattern and space type. In step SA6, the information processing unit 30b acquires the land pattern acquired in step SA2 and the space acquired in step SA3. The second search key table K2 corresponding to the combination of types is referred to. FIG. 5B shows, as an example, a second search key table K2 corresponding to the case of land pattern: office district, space type: coffee shop.
The second search key table K2 is a table that stores a search key in association with each combination of the day of the week and the time zone to which the time belongs.
Here, depending on the combination of the day of the week and the time zone to which the current time belongs, the state and atmosphere of the place where the display device 12 is provided are different, and the video corresponding to the environment is also different. For example, the atmosphere of the place is different between weekday mornings and holiday nights, and the images that customers feel comfortable with are different. The second search key table K2 associates search keys for searching for image information, text information, and audio information corresponding to the environment for each combination of the day of the week and the time zone to which the current time belongs. Remember.
In step SA6, the information processing unit 30b refers to the second search key table K2, and specifies the search key associated with the combination of the day of the week and time acquired in step SA5 as the second search key. . For example, in the example of FIG. 5B, when the day of the week is “Monday” and the time zone is “10:00 to 12:00”, the information processing unit 30b uses “morning” as the second search key for image information. ”,“ Today's weather ”as the second search key for text information, and“ Classic ”as the second search key for music information.
In this example, the date and time information is the day of the week and the time, but as the date and time information, information including the concept of “time” such as date, day of the week, season, etc. can be widely used.

After specifying the second search key, the environment information acquisition unit 30a communicates with the device-side control unit 40 of the display device 12 in accordance with a predetermined protocol, and acquires a captured image based on the image captured by the camera device 44. (Step SA7). Here, the captured image acquired by the environment information acquisition unit 30a is captured at a time as close as possible to the current time.
Next, the information processing unit 30b acquires the brightness (bright / dark) around the display device 12 based on the captured image acquired by the environment information acquisition unit 30a (step SA8). For the determination, all existing methods can be applied. For example, the average value of the gradation values of the color components of a part or all of the pixels constituting the captured image is calculated, and the calculated average value and a predetermined value are determined. This is performed by comparison with the threshold value.
Next, the information processing unit 30b refers to the third search key table K3, and specifies the third search key based on the brightness around the display device 12 acquired in step SA8 (step SA9).
FIG. 5C is a diagram schematically illustrating an example of the third search key table K3.
The third search key table K3 exists for each combination of land pattern and space type. In step SA9, the information processing unit 30b acquires the land pattern acquired in step SA2 and the space acquired in step SA3. The third search key table K3 corresponding to the combination of types is referred to. FIG. 5C shows, as an example, a third search key table K3 in the case of land pattern: office district and space type: coffee shop.
The third search key table K3 is a table that stores a search key in association with each brightness (bright / dark).
Here, depending on whether the periphery of the display device 12 is bright or dark, the state and atmosphere of the place where the display device 12 is provided are different, and the image corresponding to the environment is also different. For example, when the display device 12 is bright, the space provided with the display device 12 tends to be lively. When the display device is dark, the space provided with the display device 12 tends to be calm. The third search key table K3 associates search keys for searching image information, text information, and audio information corresponding to the environment for each brightness (bright / dark) around the display device 12. Remember.
In step SA9, the information processing section 30b refers to the third search key table K3, and specifies the search key associated with the brightness (bright / dark) acquired in step SA8 as the third search key. For example, in the example of FIG. 5C, when the brightness around the display device 12 is “bright”, the information processing unit 30 b specifies “bright” as the third search key for image information and audio information. .

Now, after specifying the third search key, the information processing unit 30b, based on the photographed image acquired by the environment information acquisition unit 30a in step SA7, the number of humans present in the vicinity of the display device 12 (more / less) ) Is acquired (step SA10). All the existing methods can be applied to the process of step SA10. For example, the information processing unit 30b performs existing face detection on the captured image, detects the number of human faces reflected in the captured image, compares the detected number of human faces with a predetermined threshold, The number (many / few) of humans present around the display device 12 is acquired.
Next, the information processing unit 30b refers to the fourth search key table K4, and specifies the fourth search key based on the number of people present around the display device 12 acquired in Step SA10 (Step SA11).
FIG. 5D is a diagram schematically illustrating an example of the fourth search key table K4.
The fourth search key table K4 exists for each combination of land pattern and space type. In step SA11, the information processing unit 30b acquires the land pattern acquired in step SA2 and the space acquired in step SA3. The fourth search key table K4 corresponding to the combination of types is referred to. FIG. 5D shows, as an example, a fourth search key table K4 in the case of land pattern: office district, space type: coffee shop.
The fourth search key table K4 is a table that stores a search key in association with each person's number (many / few) around the display device 12.
Here, depending on whether there are many or few people around the display device 12, the state and atmosphere of the place where the display device 12 is provided are different, and the images corresponding to the environment are also different. The fourth search key table K4 is a search key for searching for image information, text information, and audio information corresponding to the environment for each person (many / small) in the vicinity of the display device 12. Are stored in association with each other.
In step SA11, the information processing section 30b refers to the fourth search key table K4, and specifies the search key associated with the number of humans (more / less) acquired in step SA10 as the fourth search key. For example, in the example of FIG. 5D, when there are “many” people around the display device 12, the information processing unit 30 b identifies “lively” as the fourth search key for image information and audio information. To do.

After specifying the fourth search key, the environment information acquisition unit 30a communicates with the device-side control unit 40 of the display device 12 in accordance with a predetermined protocol, and acquires the sound collection information generated by the voice processing unit 45. (Step SA12).
Next, the information processing unit 30b determines whether music is flowing in the place where the display device 12 is installed based on the sound collection information acquired by the environment information acquisition unit 30a (step SA13). For this determination, all existing methods can be used. For example, the state of a specific band of the sound waveform indicated by the sound collection information, the peak pitch of the waveform, and the like are analyzed, and it is determined whether music is flowing based on the analysis result.
If it is determined that music is not flowing (step SA13: NO), the information processing section 30b moves the processing procedure to step SA16.
On the other hand, if it is determined that music is flowing (step SA13: YES), the information processing unit 30b further analyzes the sound collection information to determine whether the flowing music is up-tempo or low-tempo. (Step SA14). For this determination, all existing methods can be used. For example, the information processing unit 30b extracts a drum rhythm pattern based on the sound waveform indicated by the sound collection information, and determines whether the music is up-tempo or low-tempo based on the drum rhythm pattern.

Next, the information processing section 30b refers to the fifth search key table K5 and specifies the fifth search key based on the determination result of step SA15 (step SA15).
FIG. 5E is a diagram schematically illustrating an example of the fifth search key table K5.
The fifth search key table K5 exists for each combination of land pattern and space type. In step SA15, the information processing unit 30b acquires the land pattern acquired in step SA2 and the space acquired in step SA3. The fifth search key table K5 corresponding to the combination of types is referred to. FIG. 5E shows, as an example, a fourth search key table K4 in the case of land pattern: office district and space type: coffee shop.
The fifth search key table K5 is a table that stores a search key in association with each music tempo (up tempo / low tempo).
Here, depending on the tempo of the music flowing in the place where the display device 12 is installed, the state and atmosphere of the place where the display device 12 is provided are different, and the image corresponding to the environment is also different. For example, when the music being played is at a low tempo, the atmosphere around the display device 12 tends to be a calm atmosphere. The fifth search key table K5 stores a search key for searching image information, text information, and audio information corresponding to the environment in association with each music tempo (up tempo / low tempo).
In step SA15, the information processing unit 30b refers to the fifth search key table K5 and specifies the search key associated with the music tempo determined in step SA14 as the fifth search key. For example, in the example of FIG. 5E, when the music is at a low tempo, the information processing unit 30b specifies “chic” as the fifth search key of the image information.
In this example, the music tempo is determined in step SA14. However, the music genre may be determined, and the fifth search key corresponding to the genre may be specified.
If it is determined in step SA13 that music is playing, the information processing unit 30b sets a predetermined flag. Then, when providing the video distribution service, the information processing unit 30b does not search, collect, and output the audio information to the display device 12. This is because if the sound is output from the display device 12 in a state where music is flowing in the place where the display device 12 is installed, the sounds may overlap and give the user an unpleasant feeling.

Now, after specifying the fifth search key, the environment information acquisition unit 30a accesses the weather information notification server 21 via the Internet 11 and acquires weather information indicating the weather at the place where the display device 12 is installed. (Step SA16). In this example, it is assumed that the weather information is information indicating one of rain / cloudy / sunny weather.
Next, the information processing section 30b refers to the sixth search key table K6 and specifies the sixth search key based on the weather information acquired in Step SA16 (Step SA17).
FIG. 5F is a diagram schematically illustrating an example of the sixth search key table K6.

In step SA17, the information processing unit 30b acquires the land pattern acquired in step SA2 and the space acquired in step SA3. The sixth search key table K6 corresponding to the combination of types is referred to. FIG. 5F shows, as an example, a sixth search key table K6 in the case of land pattern: office district and space type: coffee shop.
The sixth search key table K6 is a table that stores a search key in association with each weather (rain / cloudy / clear).
Here, depending on the weather at the place where the display device 12 is installed, the state and atmosphere of the place where the display device 12 is provided are different, and the images corresponding to the environment are also different. And the 6th search key table K6 matches and memorize | stores the search key for searching the image information corresponding to environment, text information, and audio | voice information for every weather.
In step SA17, the information processing section 30b refers to the sixth search key table K6, and specifies the search key associated with the weather acquired in step SA16 as the sixth search key. For example, in the example of FIG. 5F, when the weather is “rain”, the information processing unit 30b specifies “rain” as the sixth search key for each of image information, text information, and audio information.

Next, the information processing unit 30b searches for image information, text information, and audio information when providing the video distribution service based on the first search key to the sixth search key specified by the above-described means. An expression (search condition) is generated (step SA18).
The search expression is generated as follows, for example. That is, taking image information and text information as an example, the information processing unit 30b uses a logical sum of the identified first search key to sixth search key as a search expression (search condition). In the example given in the description of the flowchart of FIG. 4, the search formula for image information is “luxury (first search key) or morning (second search key) or bright (third search key) or lively (first 4 search key) or chic (fifth search key) or rain (sixth search key), while the text information search formula is "economic news (first search key) or today's weather (second search key) Or rain (6th search key) ".
In the above example, the logical sum of each search key is used as a search formula, but the configuration of the search formula is not limited to this. For example, by taking a logical sum for a specific search key, the logical sum and logical product are used in a predetermined manner, a partial match search is used, a priority is given to the search key, or "weight" May be attached. That is, any method can be used as long as a search expression is generated from the specified search key.
After generating the search formula in step SA18, the information processing unit 30b searches and collects image information, text information, and voice information according to the generated search formula by the above-described method, and based on the collected information. The video information is generated, and the video is displayed on the display device 12 based on the video information.

  As described above, the video distribution server 10 according to the present embodiment acquires information (environment information) related to the environment in which the display device 12 is installed by the environment information acquisition unit 30a, and based on the acquired environment information, A search key used for generation is specified, and a search expression is generated using the specified search key. That is, the search formula (search condition) is changed according to the environment in which the display device 12 is installed. For this reason, the video distribution server 10 can search and collect video information, text information, and audio information corresponding to the environment in which the display device 12 is installed. It is possible to display an image corresponding to the environment in which the device 12 is installed.

Now, the video distribution server 10 according to the present embodiment further provides the following bookmark service.
That is, in the present embodiment, during the provision of the video distribution service, an image based on the image information and a text based on the text information are displayed in combination on the display panel 41a of the display device 12 (see FIG. 3). Here, the text based on the text information is, for example, news, articles, a part of a diary recorded by another person, text posted by another person, advertisement, etc., but a user who visually recognizes the display device 12 May be interested in the displayed text and wants to know more, or has some inspiration and wants to see it again later. The bookmark service is a service that assumes the above cases.
A user who receives the bookmark service needs to install a dedicated application having a function described below in the mobile phone 15 (terminal) owned by the user in advance. The application is provided by a service provider, and is installed in the mobile phone 15 via an existing application download service or the like.

FIG. 6 is a flowchart showing the operation of the video distribution server 10 when the bookmark service is provided.
As a premise of the flowchart of FIG. 6, the following operation is performed by the user. That is, the user who is viewing the video displayed on the display device 12 by the video distribution service starts up a dedicated application for his / her mobile phone 15. And if there is something that is worrisome about the text displayed on the display panel 41a while visually recognizing the video, the mobile phone 15 is subjected to a predetermined operation (for example, a predetermined icon displayed on the touch panel of the mobile phone 15). Touch operation). Then, predetermined data including an identification code for uniquely identifying the mobile phone 15 is transmitted from the mobile phone 15 to the video distribution server 10 via the Internet by the function of the dedicated application (step SX1). .
When the predetermined data is input, the information processing unit 30b of the control unit 30 of the video distribution server 10 acquires information related to the text information included in the video information currently being output to the display device 12 (step). SB1). In the present embodiment, the information related to the text information is text information and the URL of the text information provider. For example, when the text information is information related to news, the URL of the text information providing source is a page (may be another page such as a main page) in which information related to the news is described. For example, when the text information is a part of the text of the blog, it is the URL of the page related to the blog. The URL is stored in a predetermined storage area in association with the text information when the information processing unit 30b searches the text information. Note that the information related to the text information may include a server that provided the text information, information about companies, individuals, and the like.
Next, the information processing unit 30b stores information related to the text information in a predetermined storage area of the storage unit 33 in association with the identification code of the mobile phone 15 (step SB2).

Thereafter, the information processing unit 30b monitors whether there is a request for output from the mobile phone 15 for information related to the stored text information (step SB3). Here, in the application installed in the mobile phone 15, data for requesting output of information related to the text information together with the identification code of the mobile phone 15 is transmitted via the Internet 11 in accordance with a user instruction. A function for transmitting to the distribution server 10 is implemented, and the user starts an application and makes the above request by the function of the application.
When there is a request for outputting information related to the text information (step SB3: YES), the information processing unit 30b uses the identification code of the mobile phone 15 as a key to provide information related to the text information stored in the storage unit 33. (Step SB4), and the acquired information is output to the mobile phone 15 via the Internet 11 according to a predetermined protocol (step SB5), and text information and text information are displayed on the touch panel of the mobile phone 15. Display information related to.

The functional configuration of the video distribution server 10 according to the present embodiment is the same as the functional configuration of the video distribution server 10 according to the first embodiment. With reference to FIG. 2, detailed description of each component is omitted.

The inventors have found that when "human emotion" is defined (expressed), a considerable number of definitions are possible. For example, human emotions such as “I don't feel motivated”, “I can't expect”, “I want to laugh”, “I want to cry”, “I want to feel calm” can be defined in various ways. Hereinafter, the defined human emotion is referred to as “defined emotion K”.
Further, the inventors have several psychological effects (hereinafter referred to as “psychological effects”) that image information, text information, and audio information (hereinafter simply referred to as “contents”) give to humans. It discovered that it could classify | categorize into 10 or more. Psychological efficacy is a conceptual representation of the psychological effects and effects that a viewer who has viewed content receives from the content. For example, there are a psychological effect of “improvement of power”, a psychological effect of “make calm”, a psychological effect of “make fun”, and the like. Hereinafter, the classification of psychological efficacy is referred to as “psychological efficacy classification S”.
In addition, for the viewers who have a certain emotion, the inventors have the most effective psychological impact on the viewer when providing content belonging to a certain psychological effect category. Found that can give. For example, when there is a psychological effect type S of “improvement”, for a viewer who has a feeling of “not motivated”, the psychological effect type S related to “improvement” When the content to which it belongs is provided, the psychological influence can be exerted most effectively.
Further, the inventors have found that the psychological efficacy types S classified into several to several tens can be grouped into several groups according to the “trend” of the psychological efficacy. Based on this, the inventors grouped the psychological efficacy types into several groups, and gave each group a tag that can be added as metadata to the content (hereinafter referred to as “large tag D”). did.

FIG. 7 is a diagram schematically illustrating the relationship between the definition emotion K, the psychological effect type S, and the large tag D.
In the example of FIG. 7, 100 defined emotions K, defined emotions K1 to K100, are defined as defined emotions K. Furthermore, 15 psychological effect types S of psychological effect types S1 to S15 are defined as psychological effect types S. Each of the definition emotions K1 to K100 is associated with one of the psychological effect types S1 to S15 from the viewpoint of “most effectively having a psychological influence on the viewer”. In the example of FIG. 7, the definition emotion K1 “not motivated” and the psychological effect type S1 “improvement” are associated with each other, but this has an emotion “not motivated”. If the content belonging to the psychological efficacy type S related to “improvement of energy” is provided to the viewer who is, the association is performed in consideration of the most effective psychological influence. It has been broken.
In the example of FIG. 7, five large tags D of large tags D1 to D5 are defined as large tags D. Each of the psychological effect types S1 to S15 is associated with one of the large tags D. As described above, the large tag D is a tag given to each group after the psychological efficacy type S is grouped according to the “trend” of the psychological efficacy, and the psychological efficacy types S1 to S1. Each of S15 is associated with a large tag D corresponding to its own group.

The relationship between the definition emotion K, the psychological effect type S, and the large tag D shown in FIG. 7 is stored as data in the storage unit 33 of the video distribution server 10. The relationship between these information can be changed at any time by human means or by automatic means, and addition of information (addition of a newly defined definition emotion K, etc.) is also possible at any time.
Hereinafter, the data indicating the relationship between the definition emotion K, the psychological efficacy type S, and the large tag D stored in the storage unit 33 is referred to as “large tag relationship data”. As shown in FIG. 7, one definition emotion K is linked to one large tag D via the corresponding psychological effect type S, and the control unit 30 of the video distribution server 10 uses this large tag. By referring to the relational data, it is possible to identify one large tag D corresponding to a certain definition emotion K.

In the present embodiment, the image information providing server 18 (see FIG. 1) stores and provides image information (content) with a large tag D as metadata. For example, the large tag D as metadata for image information is given as follows.
For example, based on the fact that each of the large tags D is a tag defined for each psychological efficacy trend of the psychological efficacy category S, an expert on content understands the content of the content, By means, an appropriate large tag D is assigned to the image information (content).
In addition, for example, a user who accesses image information (content) collects what image information (content) is accessed by what means when feelings, and based on the collected information, The large tag D is given to the image information (content) by an automatic means or an automatic means. As an example, when the user accesses the content, it is configured to take an online questionnaire about the emotion at that time, and the result of the questionnaire is accumulated in association with the content, and the accumulated questionnaire result is obtained by human means, or Then, analysis is performed by an automatic means using a program, and a large tag D is given to the image information (content) based on the analysis result. As another example, the image information (content) selector can acquire biological information (pulse, body temperature, blood pressure, etc.) when accessing the image information (content), and the acquired biological information is the content. The psychological state when the content is selected is analyzed based on the accumulated information, and the large tag D is given to the image information (content) based on the analysis result.
Similarly to the image information in the image information providing server 18, the text information in the text information providing server 19 (see FIG. 1) and the voice information in the voice information providing server 10 (see FIG. 1) are also appropriate as metadata. Large tag D is given.

As described above, in this embodiment, the “human emotion” can be defined innumerably, while the content can be classified into several to ten from the viewpoint of psychological efficacy, and further, the psychological efficacy classification S Found that it can be grouped into several groups depending on the “trend” of its psychological efficacy. Finally, all of the defined definition emotions K are linked to about several (in this example, five) large tags D via the psychological effect type S. By associating the definition emotion K and the large tag D with such a technique, the human emotions that can be defined innumerably are appropriately metabolized based on the emotion characteristics and content characteristics. It became possible to link with objective information that can be used to select content as tags as data.
The number of large tags D is about several (in this example, five). Therefore, the content is not subdivided for each large tag D, that is, a large number of contents to which a certain large tag D is assigned can be secured. As a result, when content is searched using one large tag D as a key, a large number of content can be searched, and by displaying videos related to the searched large number of contents via the display device 12, etc. As in the first embodiment, it is possible to display an image that improves user satisfaction without getting tired of the user.

Next, the operation when the video distribution server 10 according to the present embodiment outputs video information to the display device 12 and displays the video on the display device 12 (during video distribution service) will be described.
FIG. 8 is a flowchart showing the above operation. In particular, FIG. 8 shows the operation of the video distribution server 10 when displaying on the display device 12 a video composed of an image based on image information and a text based on text information.
First, the environment information acquisition unit 30a of the control unit 30 of the video distribution server 10 acquires the definition emotion K corresponding to the emotion of the viewer of the display device 12 as environment information (step SC1).

Acquisition of the definition emotion K as environmental information is performed as follows, for example.
For example, first, factors affecting human emotions (hereinafter referred to as “external factors”) such as the above-mentioned land pattern, space type, current time zone, day of the week, weather, season, temperature, humidity, etc. And the definition emotion K are stored in association with each other. The correspondence between the combination of external factors and the definition emotion K is appropriate after considering the effect of each external factor on human psychology and the effect of the combination of external factors on human psychology. To be done. For example, in the case of land pattern = office district, space type = coffee shop, day of the week = Friday, weather = sunny, season = winter, humans tend to have the feeling of "I want to be fun" Correspondence is appropriately performed from the viewpoint. In step SC1, the environment information acquisition unit 30a acquires each of the external factors and specifies the definition emotion K associated with the acquired combination of external factors, thereby determining the definition emotion K as the environment information. Get as.
Also, for example, the viewer of the display device 12 is made to install a dedicated application in advance on the mobile phone owned by the viewer. This application has a function of providing a user interface for the viewer to select his / her current emotion, and the viewer selects and confirms his / her emotion via the user interface. In the user interface, selectable viewer emotions are prepared based on the defined definition emotion K. When the user's selection of his / her emotion is confirmed, information indicating the selected emotion is transmitted to the video distribution server 10 together with the position information of the mobile phone via the Internet 11 by the function of the application. The environment information acquisition unit 30a identifies the corresponding display device 12 based on the position information of the mobile phone, and identifies the defined emotion K corresponding to the viewer's emotion based on the information indicating the selected emotion. . As described above, the environment information acquisition unit 30a acquires the definition emotion K.
Further, for example, the environment information acquisition unit 30a acquires a captured image based on the image captured by the camera device 44 of the display device 12 through communication. Then, the environment information acquisition unit 30a analyzes the viewer's facial expression displayed in the captured image by an optical method, or analyzes the atmosphere of the space by an optical method using the same method as in the first embodiment. The viewer's emotion is estimated and the corresponding definition emotion K is specified.
Further, for example, when the viewer is equipped with a device for detecting biological information such as a heart rate monitor or a sphygmomanometer, the environment information acquisition unit 30a acquires the biological information from the device via communication and acquires the information. The viewer's emotion is estimated based on the biometric information, and the corresponding definition emotion K is specified.
The method for acquiring the definition emotion K has been described above with an example, but the method is not limited to the above example, and it goes without saying that all existing methods can be applied. For example, the viewer's emotion may be estimated by reflecting both the combination of external factors and the analysis result of the captured image based on the image captured by the camera device 44, and the corresponding defined emotion K may be identified. .

When the definition emotion K as environment information is acquired by the environment information acquisition unit 30a, the information processing unit 30b refers to the above-described large tag relation data stored in the storage unit 33 (step SC2) and acquired in step SC1. One large tag D corresponding to the definition emotion K is specified (step SC3). As described above, each of the defined emotions K is linked to one large tag D via the psychological effect type S. By referring to the large tag relation data, each defined emotion K is assigned to one defined emotion K. Based on this, one corresponding large tag D can be identified.
Next, the information processing unit 30b searches and acquires image information and text information using the large tag D identified in step SC3 as a search key. As described above, a large tag D appropriate as metadata is assigned to image information and text information. The image information and text information searched here are information reflecting viewers' emotions.
Next, the information acquisition unit 30b generates image information by combining the image information and the text information by the method described in the first embodiment (step SC5), and outputs the generated image information to the display device 12. The video based on the video information is displayed (step SC6).
Here, since the video displayed on the display device 12 is a video that has a psychological effect on the viewer effectively, it leads to an improvement in the satisfaction of the viewer, and further, an additional video distribution service is added. Value can be improved.
