The first content displayed by the application A is, for example, a list screen of news articles, and includes links to a plurality of second contents (that is, elements associated with the second contents).

Before the web browser B is started, the display terminal 1 requests data for displaying the second content for at least one of the plurality of second contents linked from the first content (FIG. 2). The look-ahead data request) is transmitted to the article management server 3 (c).

The web browser B is an application or component different from the application A for displaying the second content on the display unit of the display terminal 1. Since the web browser B needs data for specifying the display mode and operation in order to display the content, the web browser B receives the style data and the script data in addition to the text data and the image data from the external server and displays the content. .. The style data is data that specifies the display mode of the content, and is, for example, CSS (Cascading Style Sheets). The script data is data that specifies the operation of the content, for example, Javascript (registered trademark).

The display terminal 1 receives text data, style data, and script data among the data for displaying the second content from the article management server 3 as look-ahead data (first data), and stores the data in the storage unit (d). ..

The user operates the display terminal 1 to select a link to any second content on the application A. The display terminal 1 activates the web browser B (e) when the user selects a link to any of the second contents on the application A.

The display terminal 1 transmits a data request for displaying the second content (web data request in FIG. 2) to the web server 4 (f). The display terminal 1 receives image data from the web server 4 as web data (second data) among the data for displaying the second content (g).

The display terminal 1 uses the web browser B to display the second content on the display unit based on the look-ahead data received from the article management server 3 and the web data received from the web server 4. The content displayed by the web browser B is, for example, a detail screen of a news article.

In this way, the display system S displays the content using the pre-reading data received in advance when transitioning from the first content displayed by the application A to the second content displayed by the web browser B. Therefore, even when transitioning between different applications or components, the time required for screen display can be shortened.

[Explanation of display method]
FIG. 4 is a schematic diagram of data received by the display terminal 1 from the application server 2, the article management server 3, and the web server 4. The application data C is data for displaying the first content received by the display terminal 1 from the application server 2. The application data C includes text data C1 and image data C2.

The look-ahead data D is data for displaying the second content received from the article management server 3 before the display terminal 1 starts the web browser B. The look-ahead data D includes text data D1, style data D2, and script data D3.

The web browser data E is data for displaying the second content received from the web server 4 after the display terminal 1 starts the web browser B. When the display terminal 1 displays the pre-read second content, the web browser data E includes the image data E4. When the display terminal 1 displays the second content that has not been read ahead, the web browser data E includes text data E1, style data E2, and script data E3 in addition to the image data E4.

In the display method according to the present embodiment, the user of the display terminal 1 first operates the operation unit 13 to perform an operation for starting the application A. In the display terminal 1, the operation reception unit 111 starts the application A in response to an operation by the user. When the application A is started, the receiving unit 112 transmits the request of the application data C to the application server 2.

When the application server 2 receives the request for the application data C from the display terminal 1, the application server 2 reads the application data C from the storage unit 21 and transmits the application data C to the display terminal 1. In the display terminal 1, the receiving unit 112 receives the application data C from the application server 2.

The display control unit 113 causes the display unit 14 to display the first content based on the application data C (text data C1 and image data C2) received from the application server 2 by using the application A.

FIG. 5 is a front view of the display terminal 1 executing the application A. The application A displays a plurality of texts A1 corresponding to the text data C1 and a plurality of images A2 corresponding to the image data C2 as the first content. The plurality of texts A1 and the plurality of images A2 included in the first content are each linked to the second content that can be transitioned from the first content (that is, each is associated with the second content). Here, the first content displayed by the application A is a list screen of news articles, but other contents may be used.

Before the web browser B is started, the look-ahead unit 114 of the display terminal 1 determines at least one of the plurality of second contents linked from the first content as the look-ahead target. The look-ahead unit 114 may determine all of the plurality of second contents linked from the first content as read-ahead targets. Alternatively, the look-ahead unit 114 may determine a predetermined number of second contents from the top among the plurality of second contents linked from the first contents as the look-ahead target. Alternatively, the look-ahead unit 114 may determine the second content included in the display range of the display unit 14 among the plurality of second contents linked from the first content as the look-ahead target.

Then, the pre-reading unit 114 transmits a request for pre-reading data D indicating identification information (for example, a serial number or an address on the network) that identifies the second content to be pre-read to the article management server 3. The request for the look-ahead data D is transmitted before the web browser B is started, when the receiving unit 112 transmits the request for the application data C using the application A, or when the display control unit 113 uses the application A. This is performed when the display of the first content is completed.

When the article management server 3 receives the request for the look-ahead data D from the display terminal 1, the article management server 3 reads the look-ahead data D from the storage unit 31 and transmits it to the display terminal 1. In the display terminal 1, the look-ahead unit 114 receives the look-ahead data D from the article management server 3 and stores it in the storage unit 12. The look-ahead unit 114 may request and receive the look-ahead data D only once or repeatedly when displaying the first content.

After the look-ahead unit 114 receives the look-ahead data D, the content of the second content may be updated. Therefore, the look-ahead unit 114 may request and receive the look-ahead data D a plurality of times at predetermined time intervals (for example, every 3 minutes) after the display control unit 113 completes the display of the first content. As a result, the consistency between the content of the second content and the look-ahead data D can be maintained.

The user operates the display terminal 1 to select a link to any second content on the application A. In the display terminal 1, the operation reception unit 111 activates the web browser B in response to an operation by the user. When the web browser B is activated, the receiving unit 112 determines whether or not the display terminal 1 is connected to the network (that is, whether or not communication is possible).

When the receiving unit 112 determines that the display terminal 1 is not connected to the network, the display control unit 113 uses the web browser B and based on the look-ahead data D stored in the storage unit 12, the second content Is displayed on the display unit 14.

On the other hand, when the receiving unit 112 determines that the display terminal 1 is connected to the network, does the receiving unit 112 store the look-ahead data D indicating the second content selected by the user in the storage unit 12. Further determine whether or not.

When the receiving unit 112 determines that the display terminal 1 is connected to the network and the look-ahead data D is stored in the storage unit 12, the receiving unit 112 requests the web browser data E including the image data E4 to the web server. Send to 4.

When the web server 4 receives the request for the web browser data E including the image data E4 from the display terminal 1, the web server 4 reads the image data E4 from the storage unit 41 and transmits the image data E4 to the display terminal 1. In the display terminal 1, the receiving unit 112 receives the image data E4 from the web server 4. As a result, when the user selects the second content to be read ahead, the receiving unit 112 receives only the image data E4 out of the data for displaying the second content from the web server 4, so that the reception is started. You can save time.

Then, the display control unit 113 displays the second content on the display unit 14 based on the look-ahead data D stored in the storage unit 12 and the web browser data E received from the web server 4 by using the web browser B. Let me.

When the receiving unit 112 determines that the display terminal 1 is connected to the network and the look-ahead data D is not stored in the storage unit 12, the text data E1, the style data E2, the script data E3, and the image data E4 The request for the web browser data E including the above is transmitted to the web server 4.

When the web server 4 receives the request for the web browser data E including the text data E1, the style data E2, the script data E3, and the image data E4 from the display terminal 1, the text data E1 and the style data E2 are stored from the storage unit 41. The script data E3 and the image data E4 are read out and transmitted to the display terminal 1. In the display terminal 1, the receiving unit 112 receives the text data E1, the style data E2, the script data E3, and the image data E4 from the web server 4. As a result, even when the user selects the second content that is not the read-ahead target, the receiving unit 112 can receive all the data for displaying the second content from the web server 4.

Then, the display control unit 113 causes the display unit 14 to display the second content based on the web browser data E received from the web server 4.

6 (a) and 6 (b) are front views of the display terminal 1 running the web browser B. FIG. 6A shows the web browser B when the display terminal 1 is connected to the network, and FIG. 6B shows the web browser B when the display terminal 1 is not connected to the network. There is.

In the case of FIG. 6A, the web browser B displays the text B1 corresponding to the text data D1 and the image B2 corresponding to the image data E4 as the second content. Further, the web browser B sets the display mode of the text B1 and the image B2 (for example, the color and size of the text B1, the size of the image B2, etc.) based on the style data D2 and E2. Further, the web browser B sets the operation of the text B1 and the image B2 (for example, the dynamic change of the text B1 and the image B2) based on the script data D3 and E3.

In the case of FIG. 6B, the web browser B displays the text B1 corresponding to the text data D1 as the second content. Further, the web browser B sets the display mode of the text B1 based on the style data D2 and E2. Further, the web browser B sets the operation of the text B1 and the like based on the script data D3 and E3.

In this way, since the display terminal 1 receives the look-ahead data D while displaying the first content, the screen can be displayed in a short time when transitioning from the first content to the second content. Further, the display terminal 1 displays at least a part of the second content by using the look-ahead data D even when the display terminal 1 is not connected to the network due to a change in the network environment during the display of the first content. can.

[Modification example]
The look-ahead unit 114 may receive the look-ahead data D, which is a collection of data of a plurality of second contents. FIG. 8 is a schematic diagram of look-ahead data D received by the display terminal 1 from the article management server 3. In this modification, the look-ahead data D includes text data D1, style data D2, and script data D3 for each of the plurality of second contents. The example of FIG. 8 represents the first page, the second page, and the third page linked from the first content as the plurality of second contents.

Before the web browser B is started, the look-ahead unit 114 transmits a request for look-ahead data D indicating identification information that identifies a plurality of second contents to be read-ahead to the article management server 3.

When the article management server 3 receives the request for the look-ahead data D from the display terminal 1, the article management server 3 reads the look-ahead data D of the plurality of second contents indicated by the request for the look-ahead data D from the storage unit 31. Next, the article management server 3 collectively compresses (encodes) the pre-reading data D of the plurality of second contents, and generates the pre-reading data D which is one compressed data. The article management server 3 can use a known compression method (encoding method) to collectively compress the look-ahead data D. Then, the article management server 3 transmits the pre-reading data D, which is the generated compressed data, to the display terminal 1.

In the display terminal 1, the look-ahead unit 114 receives the read-ahead data D, which is compressed data, from the article management server 3. The look-ahead unit 114 decompresses (decodes) the look-ahead data D, which is compressed data, to generate the look-ahead data D of each second content, and stores the read-ahead data D in the storage unit 12.

In general, text data, style data, and script data have a higher compression ratio than image data. Therefore, the article management server 3 can generate a small amount of compressed data by collectively compressing the pre-reading data D (text data D1, style data D2, and script data D3) of the plurality of second contents. By receiving the compressed look-ahead data D, the display terminal 1 can greatly reduce the communication capacity required for look-ahead.

In particular, style data such as CSS is often reused in a plurality of contents. Therefore, by combining the style data of the plurality of second contents into the look-ahead data D, the display terminal 1 does not need to send and receive the same style data many times, so that the communication capacity can be reduced.
