Real-time Contents Conversion System and its Method for Coverting Wire Contents to Wireless Contents

The present invention relates to a content conversion system and a method thereof, and in particular, the present invention enables wireless Internet service by using existing HTML wired content data (static HTML data, dynamic HTML data generated by CGI) without additional conversion. A content conversion system and method and method for converting wired content to wireless content in real time to improve efficiency through data reuse and to increase price competitiveness due to human, time and material savings. A computer readable recording medium having recorded thereon a program for realization.

"101" represents a wired-based system such as a PC. The PC-based system requests "103" HTML related data according to the HTTP protocol, and "103" finds the relevant data in the system and sends it to "102".

"102" represents a wireless based system such as a mobile phone, PDA, Hand-Held PC. As with "101", the wireless-based system requests "103" radio related data according to the HTTP protocol, and "103" finds the relevant data in the system and transmits it to "102".

"103" represents a Server Program that conforms to the HTTP protocol protocol. The server receives the request from the client and searches the data for the request and returns the result.

"104" represents a data set for the wired HTML service, and there are static data in the form of HTML file and dynamic data in the form of CGI, and CGI has various forms such as PERL, ASP, and PHP.

"105" represents a data set for a wireless service. Each data such as WML series WML data, Stinger series M-HTML data, and I-MODE series C-HTML data is composed of static file type and CGI level dynamic data type.

As described above, in order to provide a conventional wireless Internet service, there is a problem in that a site for wireless Internet is separately constructed according to a wireless Internet format of each service provider together with data for wired Internet service.

That is, in the related art, a wireless Internet site needs to be reconstructed for the wireless Internet service, and a site for each language is required due to the existence of a plurality of wireless Internet languages, and modification of dynamic data (CGI) as well as static data is required. And because reconfiguration is required, there was a problem that a lot of resources, manpower, time is required.

The present invention has been made to solve the above problems, by using the existing HTML wired content data (static HTML data, dynamic HTML data generated by CGI) to convert to real-time wireless language data without special manipulation In addition, real-time conversion of wired content to wireless content, which enables real-time conversion of wireless languages (WML, M-HTML, C-HTML, S-HTML, etc.) required by the client (wireless internet terminal) without special manipulation. It is an object of the present invention to provide a computer-readable recording medium recording a content conversion system and a method thereof and a program for realizing the method.

The present invention for achieving the above object, in the content conversion method applied to the content conversion system, the first step of extracting the wired HTML data from the site in accordance with the request of the wireless Internet data of the wireless Internet user (Client) ; Extracting valid data from the extracted HTML data; And generating a wireless data by converting to a wireless language based on the valid data, and transmitting the generated wireless data to the wireless internet user.

Meanwhile, the present invention provides a content conversion system having a processor, comprising: a first function of extracting wired HTML data from a corresponding site according to a request of wireless Internet data of a wireless Internet user; A second function of extracting valid data from the extracted HTML data; And converting into a wireless language based on the valid data to generate wireless data, and then recording a program for realizing a third function of delivering the generated wireless data to the wireless Internet user. Provide a record carrier.

The wireless Internet data requested by the wireless terminal receives the request from the HTTP server, sends the URL and information of the wireless terminal to the content conversion system (H2W AutoTrans), and waits for a necessary response.

The content conversion system (H2W AutoTrans) sends URL information to the HTML data manager through the request manager and imports HTML data based on the input information.

In addition, URL information is sent to the Templete manager, the search for the templete is instructed, and the wireless data type requested by the client is transmitted to the wireless data generator.

The HTML data obtained through the HTML Data Manager and the Templete information loaded by the Templete Manager are sent to the HTML parsing and data extraction block.

HTML parsing and data extraction block performs parsing of HTML data input through HTML Parser and reformating for error correction of Html code through Html Tree Reformator.

Then, the final output data is generated through the Pattern Node Searcher and the Pattern Data Maker based on the Templete information analyzed by the Templete Analyser. Error occurred in each process is reported to Error Analyser, in this case, Error condition is reported to Client. The result from the HTML parsing and data extraction block is finally converted into wireless data for the client through the wireless data generator and responds to the HTTP server. HTTP Server transmits the response data to Client and performs wireless internet service.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
