KR20010056514A - Method for changing contents and caching for the web browser based on real-time operating system - Google Patents

Abstract

PURPOSE: A method for converting and caching contents for a browser is provided to watch all web documents in a client rapidly by embodying a function for converting contents included in a general web document into a document and an image adapt to a client format in a proxy server, and storing the converted document in a cache of the proxy server. CONSTITUTION: A client(100) requests a service, especially a contents service in a web browser(110) through a network(1002). The web browser(110) transmits a service requesting signal to a proxy server(120) in accordance with the service request(1004). The proxy server(120) receiving the service requesting signal creates a session and decides a connection allowance or not through a user's certification of the web browser(110). If the request is correct, the proxy server(120) certifies the request in accordance with connection allowance or not, and searches whether the contents exists in one's cache(1006). If the contents exist in the proxy server(120), the searched contents are transmitted to the web browser(110)(1008). A client receiving the contents displays the contents(1010). If the contents does not exist in the proxy server(120), the contents corresponded to the external web server(130) are requested(1012). The corresponded contents are taken(1014). The corresponded contents are converted into the contents adapted to a client's display device, and the contents are stored(1016). The converted contents are transmitted in a web browser(110)(1018). The web browser(110) receives the transmitted contents and displays the contents on a TV screen(1020).

Description

METHOD FOR CHANGING CONTENTS AND CACHING FOR THE WEB BROWSER BASED ON REAL-TIME OPERATING SYSTEM}

The present invention relates to a method of implementing a proxy server for a browser based on a real-time operating system. The present invention relates to a hardware environment based on a real-time operating system in order to use the Internet using a client (connected to a TV or a built-in set-top box). The present invention relates to a content conversion and caching method for converting contents such as an image, text, etc. of a general web document, and to store the converted contents, and a recording medium recording a program for implementing the method.

Recently, with the rapid spread of the Internet, the demand for using the Internet using TVs of general households is increasing. However, since most general web documents currently used on the Internet are produced for desktops, TVs having a difference in size and resolution of the desktop and the screen have difficulty in displaying general web documents.

In addition, since the characteristics of the real-time operating system has a small memory structure, the cache function is not built in itself, or even if it is embedded, its size is very small, which causes very slow speed.

The present invention has been made to solve the above problems, and implements a function in the proxy server that converts the contents contained in the general web document into a document or image format that matches the client format, and converts the converted document into the proxy server. It is an object of the present invention to provide a method for converting and caching all web documents, which can be quickly viewed on a client, and a computer-readable recording medium recording a program for realizing the method.

1 is an embodiment of a content conversion and caching method for a browser based on a real-time operating system according to the present invention.

Explanation of symbols on the main parts of the drawings

100: client 110: web browser

In the method of the present invention for achieving the above object, a content conversion and caching method applied to a proxy server connected to a plurality of clients based on a real-time operating system, the content is present in its cache when a service is requested from a predetermined client A first step of searching for and presenting the content to the client and displaying the content; if not present, requesting and receiving the content from a predetermined web server; A second step of converting the content received in the first step according to the display format of the client; And a third step of transmitting the converted content to the client for display and storing the converted content in the cache.

When a proxy server having a large capacity processor receives a service request from a predetermined client, the proxy server searches for whether the corresponding content exists in its own cache, and if so, transmits to the client for display. A first function for requesting and receiving the content; A second function of converting the content received in the first step according to the display format of the client; And a computer readable recording medium having recorded thereon a program for transmitting the converted contents to the client for display and displaying the converted content in the cache.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a flowchart illustrating an embodiment of a method for converting and caching content for a browser based on a real-time operating system according to the present invention.

First, the client 100 requests a service request, in particular, a content service, to a web browser 110 through a network (1002). The web browser 110 transmits a service request signal to the proxy server 120 according to the service request described above (1004). Upon receiving the service request signal from the web browser 110, the proxy server 120 creates a session and determines whether to allow access through user authentication of the requested web browser 110. The proxy server 120 authenticates the request if it is a correct request according to whether the connection is allowed, and searches for whether the content exists in its cache first (1006).

As a result of the search, if the above-mentioned content exists in the cache in the proxy server 120, the searched content is transmitted to the web browser 110 (1008). The client 100 receiving the content displays the content (1010).

If the proxy server 120 cannot find the corresponding contents in its cache, the proxy server 120 requests the content corresponding to the external web server 130 (1012). The content corresponding to this content request is retrieved (1014).

Corresponding contents are converted into the contents suitable for the display device of the client, in particular, the TV format and stored in the converted cache (1016),

The content on which the conversion function is performed is transmitted to the web browser 110 (1018). The web browser 110 receives the transmitted contents and displays them on a TV screen (1020).

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains, and the above-described embodiments and accompanying It is not limited to the drawing.

As described above, the present invention converts general contents produced for a TV-based content as well as a general desktop browser, and stores the converted contents in a cache, thereby reducing the memory constraints and speed of a web browser based on a real-time operating system. By preventing the degradation problem, the general TV can use the Internet faster than the existing real-time operating system-based web browser.

In addition, even if the client's display device is a TV, it is possible to view general web documents through the TV without creating new contents specifically for the TV, which enables the use of the Internet at a low cost at home. There is.
