Description

  The present invention relates to display adjustment when browsing HTML content on a server with a WEB browser.

  With the recent development of the Internet, in particular, WEB services, WEB browsers, which were previously only PCs, have come to be used in various terminal devices such as mobile phones and digital televisions. A display unit of a terminal device on which a WEB browser is mounted varies greatly in size, aspect ratio, and the like for each terminal device from a large screen of a digital television to a liquid crystal display unit of a mobile terminal. Accordingly, it is necessary to prepare content for each terminal device even if the content has the same content.

Japanese Patent Application Laid-Open No. 2004-151561 discloses a technique that can cope with many browser terminals with one content by converting the content. When the browser type is transmitted from the terminal to the server, the content is rewritten according to the corresponding conversion rule, and the content corresponding to the browser type is created, so that an optimal display is performed on the terminal.
JP 2001-195391 A

  However, in the invention of Patent Document 1, as the types of terminal devices increase, it is necessary to prepare a corresponding conversion rule in the server each time, and there is a problem that the increase in the types of terminal devices cannot be easily handled.

  The present invention addresses the above-described problems, and provides a content display system that performs optimal display on many types of terminals with only one content and display adjustment rules even when the types of terminal devices increase. The purpose is to provide.

  The content display system according to the present invention is a content display system comprising a server and a plurality of terminals, wherein the terminals calculate receiving means for receiving contents described in a markup language, and display information of the contents. Display information calculating means, display information transmitting means for transmitting the calculated display information to the server, and display means for displaying the content according to the calculated display information, wherein the server transmits the content And display information receiving means for receiving the display information calculated by the terminal, display information of the content based on the display information and display adjustment rules, and changing the content using the calculated display information Display information adjusting means.

  The content display system according to the present invention can adjust the display for each element of content for various browser terminals by transmitting and receiving display information calculated by the browser terminal between the server and the browser terminal, Without the server knowing in advance information on the display characteristics of the browser, it is possible to display content that matches the display characteristics of the browser on many types of terminals. Furthermore, there is an effect that an optimum display can be automatically obtained even for a new browser.

  The best mode for carrying out the present invention will be described below with reference to the drawings.

(Embodiment 1)
FIG. 1 is a block diagram showing a configuration of a content display system according to Embodiment 1 of the present invention. The content display system according to the present embodiment includes a web server 1 and a browser terminal 2.

  In the web server 1, 11 is a content storage unit that stores various HTML documents, 12 is a display information adjustment unit that adjusts the display position of each element of the HTML document, and 13 is a content that transmits the HTML document to the browser terminal 2. A transmission unit 14 is a display information receiving unit that receives display information on the browser terminal 2 from the browser terminal 2, and 15 is a display information storage unit that stores display information for each type of browser terminal.

  In the browser terminal 2, 21 is a content receiving unit that receives an HTML document from the web server 1, 22 is a display information calculating unit that analyzes the structure of the elements of the HTML document and calculates the display position of each element, and 23 is a display A display information transmitting unit that transmits the display information calculated by the information calculating unit 22 to the web server 1, and 24 is a display unit that displays an HTML document.

  Next, the operation of the entire processing of the content display system of the present invention will be described using the flowchart shown in FIG.

  The browser terminal 2 designates a URL or the like and requests the web server 1 to transmit an HTML document (S01).

  The web server 1 acquires information about the browser terminal 2 such as the screen size and display information from the browser terminal 2 via the display information receiving unit 14 (S02). Here, the display information is additional information used when an HTML document is displayed on the browser terminal 2.

  When there is a request for transmitting the same HTML document from the browser terminal 2 before, the web server 1 searches for the presence or absence of the display information since it is already stored in the display information storage unit 15 (S03). If the display information exists (Yes in S03), the display information is acquired from the display information storage unit 15 (S04). When the display information does not exist (No in S03), when the display information to which the readjustment unnecessary information is added is received from the browser terminal 2, the display information is displayed together with the type, screen size, and URL of the browser terminal 2. The information is stored in the information storage unit 15 (S05).

  The display information adjustment unit 12 of the web server 1 searches for a display adjustment rule corresponding to the HTML document using, for example, the URL of the HTML document as a key. The display adjustment rule can be determined for each element. For example, a rule for displaying without protruding from the screen, a rule for displaying text without line breaks, a rule for deleting preferentially when it cannot be displayed, and the like are determined for each element.

  The display information adjustment unit 12 determines whether or not the display information needs to be adjusted using the display adjustment rule (S06). If no adjustment is required (No in S06), the information that does not need to be adjusted is added to the HTML document. Is retransmitted to the browser terminal 2 (S08). For example, information that does not require adjustment is added to the HTTP header. If adjustment is necessary (Yes in S06), the position and size are determined for each element based on the acquired screen size information of the browser terminal 2 and the display adjustment rule, and display information is created (S07).

The web server 1 embeds display information as an attribute of each element of the HTML document, and transmits it from the content transmission unit 13 to the browser terminal 2. (S09)
The browser terminal 2 receives the HTML document to which the display information transmitted from the web server 1 is added by the content receiving unit 13 (S09). An HTML document is composed of a combination of elements called tags, and the elements are composed of sentences, images, figures, tables, and the like and elements that include them. When there are a plurality of elements in the content, there are elements in the elements or elements are arranged in a tree structure.

  The display information calculation unit 22 of the browser terminal 2 normally analyzes the structure of the elements of the HTML document and calculates whether or not to display each element, and if so, calculates the position and size (S10). . Regarding the overlap between elements, the BODY element, which is the top of the tree structure of the element, is arranged on the back surface, and the end element is arranged on the front surface. If they do not overlap, they are usually arranged in order from top to bottom and from left to right. If the position or size is specified, it is followed, but if the screen does not fit, the display information calculation unit 22 may change the position and size. If display information is added, the display information is calculated again in consideration of the display information (S10).

  When the result is the same as the display information transmitted from the web server 1 or when the predetermined number of adjustments is exceeded (Yes in S11), each element is displayed on the display unit as it is based on the display information (S13). ). At this time, if the display information is the same, information that does not require readjustment is added, and the display information is transmitted to the web server 1.

When the display information calculated by the display information calculation unit 22 is different from that transmitted from the web server 1 (No in S11), the display information is transmitted from the display information transmission unit 23 to the web server 1 again. (S12)
Thereafter, the web server 1 repeats the processing after obtaining the display information from the browser terminal 2 (S02).

  Note that the web server 1 that does not have the display information storage unit 15 needs to adjust the display of the content after the second time, but the other functions can be realized in exactly the same way.

  The web content display system according to the present invention enables the display of content that matches the display characteristics of the browser without the server knowing information about the display characteristics of the browser in advance. This is useful for terminals, in-vehicle terminals, digital televisions, and the like.
