Description
The present invention relates to a web viewer server, a web viewer service system using the web viewer server, and a control method thereof, and more particularly, to a web viewer terminal state (ZOOM state or display rotation state) for processing a web page in the form of an image. Accordingly, the present invention relates to a web viewer server for displaying an optimized screen of a web page in a web viewer, a web viewer service system using the web viewer server, and a control method thereof.
In general, a mobile communication terminal has a main purpose of making a voice call wirelessly, but in recent years, due to the development of mobile communication technology, various functions other than voice calls have been added to the mobile communication terminal. Among them, there has been a desire for the use of the Internet using a mobile communication terminal due to the activation of the Internet through a wired network. Accordingly, communication companies have added a function to enable the use of the wireless Internet in the mobile communication terminal.
The Internet is a service based on the Transmission Control Protocol / Internet Protocol (TCP / IP) protocol, such as e-mail, remote computer connection (telnet), file transfer (FTP), and Usenet News. ), Internet information retrieval (Gopher), Internet conversations and discussions (IRC), electronic bulletin boards (BBS), hypertext information viewing (WWW: World Wide Web), online games, etc. It mainly uses web browsing based on HTTP (HyperText Transfer Protocol).
By the way, the mobile terminal is a major feature of the portability of the mobile terminal compared to the home computer hardware specifications are inferior, which is a factor that reduces the processing speed of the wireless Internet. That is, when a function of processing a web page is added to a mobile communication terminal in the same way as a home computer, the processing speed of the web page has been significantly decreased.
Accordingly, mobile carriers have been seeking various ways to increase the user convenience of the wireless Internet to subscribers, one of which is a web viewer service system.
The web viewer service system is provided between the mobile communication terminal and the web server communication path, so that the mobile communication terminal has only a function of processing an image except for interpreting markup tags of web pages provided by the web server. The web viewer server parses and renders the web page and captures the processed web page as an image and transmits the image to the mobile communication terminal.
Such a web viewer service system requires only an image processing function to be implemented in the mobile communication terminal without having to interpret all markup tags in the mobile communication terminal, that is, a full browser function. It is widely used because it enables fast web browsing.
The mobile communication terminal used in such a web viewer service system is called a 'web viewer' from the viewpoint of processing a web page.
However, the web viewer is inconvenient compared to the full browser.
For example, when the web viewer user zooms in using the zoom function, the text of the web page being viewed is too small. As the screen zooms in, the entire web page cannot be displayed at once. You must read the web page while pressing. This example is shown in FIG.
That is, in the case of full browser, even if the screen is changed, 'text' type web page received from the web server can be parsed and rendered by itself, so it responds actively to screen enlargement and does not use the left and right scroll keys. Although there is room for viewing, there is a problem in that the web viewer does not change the form of the currently displayed web page according to the enlargement of the screen since only the web page in the form of an image is processed and displayed on the screen. This is a big complaint for users who do not like to move the screen using the left and right scroll keys when the screen is enlarged and viewed.
On the other hand, recently, a mobile communication terminal capable of rotating the display unit horizontally and vertically has been released. The above-described problems of the web viewer also appear in this case.
That is, when the user rotates the display unit vertically while viewing the web page on the horizontal screen, the left and right scroll keys are used when the web page rotated vertically on the horizontal screen without using the left and right scroll keys. The situation can only be seen by everyone.
In the case of the web viewer, the display of the web page is not actively changed according to the state of the terminal (i.e., the web viewer), which causes a great inconvenience to the user, such as the user having to operate using the scroll key.
The present invention has been made to solve the above-mentioned conventional problems, the purpose of which is to actively change the web page displayed on the web viewer according to the state of the web viewer, so that the user can easily be changed even if the state of the web viewer changes The present invention provides a web viewer server for viewing a web page, a web viewer service system using the web viewer server, and a control method thereof.
In order to achieve the above object, a web viewer for processing and displaying a web page of an image format according to the present invention, and parsing and rendering a web page received from a web server by driving a web browser, are displayed on the web browser window. The web viewer service system including a web viewer server for capturing an image of a web page and transmitting the image to the web viewer transmits a screen zoom event signal to the web viewer server when the user detects a command to execute a screen zoom function. A web viewer; A web viewer that captures a web page displayed on the adjusted web browser window and transmits it to the web viewer after adjusting at least one of the horizontal and vertical sizes of the web browser window based on the screen zoom event signal received from the web viewer It is configured to include a server.
In addition, in order to achieve the above object, in response to a web page request of a web viewer according to the present invention, the web page is received from a web server and the web browser is driven. After the parsing and rendering process, the web viewer server generating the captured image and transmitting the captured image to the web viewer, the web browser window for adjusting the size of the window of the web browser based on the status information of the display unit of the web browser received from the web viewer An adjusting unit; A web page processing unit for parsing and rendering a web page received from the web server and displaying the web page in the web browser window; And a screen capture unit for capturing an image of the web page displayed on the web browser window and transmitting the image to the web viewer.
Further, in order to achieve the above object, a web viewer for processing a web page in an image format according to the present invention and displaying it on a display unit rotated in a horizontal or vertical direction, and a web page received from a web server by driving a web browser. A control method of a web viewer service system including a web viewer server for parsing and rendering, capturing a web page displayed on the web browser window, and then transmitting an imaged web page to a web viewer, wherein the web viewer is operated by a user. Transmitting a display unit rotation event signal to the web viewer server when rotation of the display unit in the horizontal or vertical direction is detected; Changing, by the web viewer server, at least one of a width and a vertical size of a window of the driven web browser according to a display unit rotation event signal received from the web viewer; Processing, by the web viewer server, a web page received from the web server, displaying the web page on the changed web browser, capturing an image of the web page screen displayed on the web browser, and transmitting the image to the web viewer; And updating, by the web viewer, a web page previously displayed with the web page received from the web viewer server.
As described above, according to the present invention, the web viewer user can view the web page without the left and right scroll key manipulation even when the screen currently being viewed is enlarged. In addition, even in a mobile communication terminal (web viewer) having a display unit capable of rotating horizontally and vertically, an optimized web page according to the horizontal and vertical states of the display unit is displayed, so that the user can conveniently scroll the webpage (for example, scroll left and right). Can be viewed without key operation).
