Abstract

PROBLEM TO BE SOLVED: To display contents on a terminal and automatically display relevant contents on another terminal at the same timing.SOLUTION: Upon receiving an operation to display first contents (videos, images, remote control, and buttons) on a terminal 2 (user operation on the terminal 2), a display control device 1 displays, on another terminal 3, second contents (videos and images) to which an operation to the first contents (remote control and buttons) is reflected and different from the first contents, or the second contents (remote control and buttons) that are the object of the operation to reflect the first contents (videos and images) and different from the first contents.

Description

  The present invention relates to a technique for automatically displaying related content on another terminal at a timing when the content is displayed on a terminal.

  Conventionally, for example, when displaying HTML content (web page) described in HTML5, the technology of Non-Patent Document 1 or Non-Patent Document 2 is used to divide the HTML content into a plurality of contents, and each content is separated. Can be displayed on other terminals. At this time, there is a relationship between the contents, and each content may function only after all of them are assigned to the terminal. For example, when there is a video (content) and a remote controller (content) for operating the video, it is not possible to perform operations such as playback / stop of the video only by displaying the video. Similarly, the video cannot be viewed simply by displaying only the remote control. That is, a plurality of related contents must be displayed on the terminal. In Non-Patent Document 1 and Non-Patent Document 2, which terminal displays which content is set as a rule, and the content is displayed on the terminal based on the rule. However, for that purpose, it is necessary to set a rule for each Web page by a person, and there is a problem that the cost for setting the rule is high.

  As described above, when a video that cannot be operated without a remote control or a remote control that does not have a video and need not be displayed is displayed on the terminal, the display area cannot be effectively used (Problem 1). In addition, when trying to operate an image that cannot be operated without a remote control, for example, the user may click on the image and perform trial and error, but this will cause confusion to the user. The number of useless operations and operation time increase (Problem 2). Further, manually setting the content display control rule requires a large cost for setting the rule (Problem 3).

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a technology for automatically displaying related content on another terminal at the timing of displaying the content on the terminal. There is.

  In order to solve the above-described problem, the first aspect of the present invention is a display control apparatus that controls screen display of a first terminal and a second terminal, and displays first content on the first terminal. In response to the operation to be performed, the second content different from the first content that is the reflection destination of the operation on the first content, or the operation of the operation that uses the first content as the reflection destination of the operation A second content different from the target first content is displayed on the second terminal.

  A second aspect of the present invention is an operation method of a display control apparatus that controls screen display of a first terminal and a second terminal, and triggered by an operation of displaying the first content on the first terminal. The second content different from the first content that is the reflection destination of the operation on the first content, or the first content that is the operation target of the operation that reflects the first content And displaying different second contents on the second terminal.

  According to the present invention, related content can be automatically displayed on another terminal at the timing when the content is displayed on the terminal.

It is a figure which shows an example of terminal information DB12. It is a figure which shows an example of an HTML content. It is a flowchart which shows the flow of the process which the display content selection allocation process part 13 performs. It is a description example of an HTML file.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a block diagram showing a schematic configuration of the display control apparatus according to the present embodiment.

  The display control device 1 is connected to the terminals 2 and 3 via a communication line. The terminal 2 is a telephone terminal called a smartphone, while the terminal 3 is a computer having a communication function called a personal computer (personal computer), and has a browser capable of WebSocket communication, for example.

  The display control apparatus 1 includes a content DB 11 that stores content information, a terminal information DB 12 that stores terminal information, and a display content selection / assignment processing unit 13 that selects and assigns content to be displayed on the terminal.

  FIG. 2 is a diagram illustrating an example of the content DB 11.

  The content DB 11 stores a record for each content. The record includes a content ID column that stores a content ID that can uniquely identify the content, a content attribute column that stores a content attribute indicating the characteristics of the content, and a content ID that can uniquely identify the content related to the content. A content ID column is provided.

  FIG. 3 is a diagram illustrating an example of the terminal information DB 12.

  The terminal information DB 12 stores a record for each terminal. The record stores a terminal ID that can uniquely identify the terminal, and terminal information indicating the characteristics and type of the terminal. The terminal information is, for example, a smartphone or a personal computer. The terminal information DB 12 may be created manually, for example, or automatically based on the user agent of each terminal.

  FIG. 4 is a diagram illustrating an example of content.

  Each content used in the present embodiment is, for example, a part obtained by dividing one HTML file (content). For example, the content is, for example, a video, a remote control, or metadata. When a video is operated with a remote controller, the video to which the operation is reflected and the remote controller that is the operation target are mutually related contents.

(Operation of display control device 1)
In FIG. 1, the terminal 2 or the terminal 3 (here, referred to as the terminal 2) is operated by the user, and thereby the browser of the terminal 2 transmits a content display request to the display control device 1. The display control apparatus 1 receives this display request.

  FIG. 5 is a flowchart showing the flow of processing performed by the display content selection / assignment processing unit 13.

When the display request is received, the display content selection / assignment processing unit 13 acquires content to be displayed on the terminal 2 (hereinafter referred to as content C ₁ (first content)) (S1). For example, the content C ₁ is selected by the user of the terminal 2. For example, the content C ₁ is acquired from a web server (not shown).

In the following description, it is assumed that the content C ₁ is a portion obtained by dividing an HTML file as shown in FIG. In addition, it is assumed that a JavaScript (registered trademark) file is attached to the HTML file. There is also a method of describing JavaScript in the HTML file. In this case, the file may be only the HTML file.

Next, the display content selection / assignment processing unit 13 acquires the event listener registered in the content C ₁ from the HTML file using the JavaScript file, analyzes the processing content related to the content C ₁ by the event listener, and processes the processing content. Based on the above, content to be displayed on terminals other than the terminal 2 (hereinafter referred to as content C (second content)) is determined (S3).

If the content C ₁ is a video example, the content C is a remote place, for example the reproduction of the video, and the like stops. In this case, the content C is an operation target of the operation with the content C ₁ (video) as a reflection destination of the operation.

If the content C ₁ in the reverse is remote For example, the content C is a video, for example. In this case, the content C is a reflection destination of the operation to the content C ₁ (remote control).

Display content selection assignment processing section 13, for example, determine the processing to be executed in response to each event that occurs with respect to the content C ₁ from the event listener registered in the contents C _1, other than the content C ₁ in the process If processing for the content is included, the content is set as content C.

  FIG. 6 is a description example of an HTML file.

In the case of an HTML file as shown in the figure, when a click event occurs in content 2, processing for switching the display of an image with respect to content 1, specifically, when the src attribute of content 1 is image1.jpg, the src of content 1 Since the process of changing the attribute from image1.jpg to image2.jpg is executed, the display content selection / assignment processing unit 13 determines that the content 2 is the content C ₁ when the content 1 is the content C _1. When content 2 is content C ₁ , content 1 is determined as content C.

  Similarly, it is determined that the contents 1 and 3 have the same relationship.

  In this way, by using the HTML file and the JavaScript file to analyze the processing details for the event that occurred using the character string such as document.getElementById ('Picture') as a clue, it is possible to determine whether there is a relationship between the contents. Can be judged.

Returning to FIG. 5, in S <b> 3, the display content selection / assignment processing unit 13 generates a new record in the content DB 11, the content ID of the content C _{1 in} the content ID column, and the content attribute of the content C _{1 in} the content attribute column. Store. The display content selection / assignment processing unit 13 stores the content ID in the related content ID column when there is content C, and stores Null when there is no content C.

  Here, the display content selection / assignment processing unit 13 stores, for example, the ID attribute value described in the HTML file as the content ID or the content ID of the related content.

Further, the display content selection / assignment processing unit 13 stores, for example, the element name of the content C _{1 and} the terminal type (smart phone, tablet, personal computer, etc.) most suitable for displaying the content C ₁ as content attributes.

  When the content ID and the element name are “movie” indicating a video, the terminal type is, for example, a personal computer. When the content ID is “controller” indicating a remote controller, the type of the terminal is, for example, a smartphone.

These types are described in the HTML file may be obtained from the set attribute values by the content creator may be determined based on the element name of the content C _1.

In S3, when there is the content C, the display content selection / assignment processing unit 13 generates a new record in the content DB 11, sets the content ID of the content C in the content ID column, and sets the content attribute of the content C as the content attribute. Store in column. In addition, the display content selection / assignment processing unit 13 stores the content ID of the content C _{1 in} the related content ID column.

  Also in this case, the display content selection / assignment processing unit 13 stores, for example, the ID attribute value described in the HTML file as the content ID or the content ID of the related content.

Further, the display content selection / assignment processing unit 13 stores, for example, the element name of the content C _{1 and} the terminal type (smart phone, tablet, personal computer, etc.) most suitable for displaying the content C ₁ as content attributes.

In addition to the method of adding a record to the content DB 11 when the content C ₁ is acquired as described above, the content DB 11 can be created when the HTML file is first acquired from the web server.

Next, the display content selection / assignment processing unit 13 determines whether or not there is a content ID in the related content ID column of the record in which the content ID of the content C ₁ is stored in the content ID column (S5).

  If there is a content ID in the related content ID column (S5: YES), the display content selection / assignment processing unit 13 searches the content DB 11 for a record including the content ID in the content ID column, that is, a record of the content C. A content attribute is read, a record including terminal information matching the content attribute is searched from the terminal information DB 12, and a terminal (for example, terminal 3) corresponding to the terminal ID of the record is notified to display the content C. (S7). For example, the notified terminal 3 displays the content C.

  When the content C is a video, the type of the terminal described in the content attribute is, for example, a personal computer, so that the content C (video) is displayed on the personal computer (terminal 3).

The display content selection assignment processing section 13, if there is no related content ID (S5: NO), or in the next S7, to the terminal 2 which is the destination of the request for displaying the content, to display the content C ₁ (S9), and the process ends. It notified the terminal 2 displays the content C _1.

  Although the present embodiment has been described above, the number of terminals may be three or more, and the terminal that transmits the display request may not be the terminal 2. Further, in the present embodiment, the display control device 1 is provided separately from the terminal, but the display control device 1 may be configured in any terminal and the display control device 1 may not be provided separately.

  In addition, the reflection destination of the operation is not limited to a video or an image, but may be a table, a character, an application (for example, a game), or the like. Further, the operation target is not limited to the remote control and buttons, but may be a keyboard (a so-called soft keyboard displayed by software), an input area for inputting a search term, or the like.

  Further, the content is not limited to an HTML file, and other content (content created in another page description language, etc.) may be divided as content. Further, the content is not limited to a portion obtained by dividing one content, and may be individual content.

  As described above, according to the display control device 1 according to the present embodiment, the operation (implementation) for displaying the first content (video, image, remote control, button) on the first terminal (terminal 2 in the example). In the example, the second content (video, image) different from the first content, which is the reflection destination of the operation on the first content (remote control, button), or the first, triggered by the user operation of the terminal 2 Since the second content (remote control, button) that is different from the first content that is the operation target of the operation with the one content (video, image) as the reflection destination of the operation is displayed on the second terminal, At the timing when the content is displayed on one terminal, the other content (related content) can be automatically displayed on the other terminal.

  As a result, there is no video, image, or video that cannot be operated without a remote controller, buttons, etc., and a remote controller that does not require display is not displayed, and the display area can be used effectively.

  In addition, video and images that cannot be operated without a remote control, buttons, etc. are no longer displayed, and the user clicks on the video and performs operations such as trial and error. Can be prevented.

  In the present embodiment, the event listener of the first content is acquired, the processing content related to the first content is analyzed by the event listener, and the second content is determined based on the processing content. Prior rule setting is unnecessary, and the cost can be reduced.

  A computer program for causing a computer to function as the display control device of the present embodiment can be recorded on a computer-readable recording medium such as a semiconductor memory, a magnetic disk, an optical disk, a magneto-optical disk, a magnetic tape, and the Internet. It can be widely distributed by being transmitted through a communication network such as
