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

In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

1 is a block diagram illustrating a configuration of a moving picture reproducing system according to the present invention.

1, the moving image playback system includes a mobile communication terminal 110, a mobile communication server 120, a moving image server 130, and a web server 140. The mobile communication terminal 110 and the mobile communication server 120 or the mobile communication terminal 110 and the moving picture server 130 are connected through the first network 115 and are connected to the mobile communication server 120 and the web server 140, Or the video server 130 and the web server 140 are connected through the second network 125. [ The first network 115 is a mobile communication network and the second network 125 is an Internet network.

The mobile communication terminal 110 includes a browsing unit 111 and a moving image playback module 113 for displaying a predetermined web page and viewing a moving image when an Internet execution command is input. The browsing unit 111 receives image data from a mobile communication server 120 that converts HyperText Make-up Language (HTML) data of a web page into image data, and generates an image-based web page.

That is, when the Internet execution command is input, the mobile communication terminal 110 informs the mobile communication server 120 of the Internet execution command, receives the image data of the web page corresponding to the Internet execution command from the mobile communication server 120, And displays the image-based web page through the unit 111. [

When a predetermined moving image is selected in the displayed web page, the mobile communication terminal 110 transmits the coordinate data of the web page corresponding to the selected moving image to the mobile communication server 120. At this time, the mobile communication terminal 110 preferably transmits the coordinate data of the web page together with the identification information data capable of identifying itself.

Then, when the mobile communication terminal 110 receives the video access information data corresponding to the coordinate data of the web page from the mobile communication server 120, the mobile communication terminal 110 transmits the video corresponding to the video access information data to the video server 130, Upon receiving a moving image from the moving image server 130, the moving image reproducing module 113 reproduces and displays the received moving image through the moving image reproducing module 113.

When the mobile communication server 120 receives the coordinate data of the web page from the mobile communication terminal 110, the mobile communication server 120 checks the selected moving image on the web page of the mobile communication terminal 110 with the coordinate data of the received web page, Calls the socket library to exchange data with the web server 140 that is broadcasting the moving image, and hooks or intercepts a hypertext transfer protocol (Http) message transmitted from the network driver to the network. To this end, the mobile communication server 120 includes a packet hooking unit 121 for hooking a message output from the network driver. The socket library relates to a program interface for processing an input / output request of Internet applications, and a socket library in a Windows operating system is called a winsock library.

Then, the mobile communication server 120 extracts the video access information data from the Http message and stores it in the memory. More specifically, the mobile communication server 120 searches for the extension corresponding to the moving picture in the Http message, Extracts video access information data, and stores the extracted video access information data in a memory (not shown). The moving picture access information data includes host information, URL information, and cookie information, and information on a referer header (referer header) information, As shown in FIG. The wrapper header information is necessary for log analysis or access control. Also, the memory is preferably a kernel memory of a Windows operating system. For example, if the video access information data is "* .flv", "flv" is an extension corresponding to a moving image, "*" corresponds to host information, URL information and cookie information do.

This will be described with reference to FIG.

2 is a diagram illustrating two access modes in a window operating system of the mobile communication server of FIG.

The access mode of the Windows operating system is divided into a user mode and a kernel mode. The user application is executed in the user mode, and the system service or the device driver is executed in the kernel mode.

That is, the user mode corresponds to an application 10 and an application programming interface (API) 20 for providing a set of functions for an application. The kernel mode corresponds to a TCP (Transmission Control Protocol) / IP Driver 30, a Network Driver Interface Specification (NDIS) miniport driver 40, and a NIC (Network Interface Card) 50 are applicable.

The network driver 200 includes the TCP / IP protocol driver 30 and the NDIS miniport drivers 41 and 42. The TCP / IP protocol driver 30 includes one or more NDIS miniport drivers 41, 42, respectively.

Accordingly, when the mobile communication server 120 transmits the Http message to the web server 140 through the second network 125, the TCP / IP protocol driver 30 transmits a Network Driver Interface Specification (NDIS) miniport driver 40 to the NIC 50, and transmits the Http message to the NIC 50 by calling the NDIS function.

In other words, the mobile communication server 120 uses the NDIS miniport driver 40 and the NDIS miniport driver 40 to transmit and receive packets using the binding handle and the data, Hooks the NDIS packet, that is, the Http message, between the TCP / IP protocol driver 30 and the NDIS miniport driver 40 by hooking the SendHandler and SendpacketHandler functions. Then, the video access information data is filtered in the hooked NDIS packet.

The video server 130 is a server that supports RTS (Real Time Streaming). The video server 130 requests a video to the web server 140 on behalf of the mobile communication terminal 110 and receives an extension of the video received from the web server 140 Time conversion to an extension that can be reproduced by the mobile communication terminal 110 and transmits it to the mobile communication terminal 110.

In other words, when the video server 130 receives the video access information data from the mobile communication terminal 110, the video server 130 requests the video corresponding to the video access information data to the web server 140, The mobile communication terminal 110 converts the first extension of the received moving image into a predetermined second extension and transmits the converted moving image having the second extension to the mobile communication terminal 110.

Web server 140 is associated with one or more Internet sites. The Internet site includes an Internet site or a search Internet site that publishes content including a moving picture.

The mobile communication server 120 extracts the video access information data from the Http message output from the network driver 200 through the packet hooking unit 121 and transmits the video access information to the video server 130, The mobile communication terminal 110 requests the moving image corresponding to the moving image access information data to the web server 140 and converts the received moving image extension into an extension reproducible by the mobile communication terminal 110 and transmits the extension to the mobile communication terminal 110 , And the mobile communication terminal 110 can reproduce the moving picture of all the portal Internet sites through the browsing unit 111. That is, the mobile communication terminal 110 can reproduce the moving picture received from the moving picture server 130 through the browsing unit 111 without having to install a dedicated program for playing the moving picture having various extensions.

FIG. 3 is a flowchart illustrating an operation method of the moving picture reproducing system according to the present invention.

When an Internet execution command is inputted (S301), the mobile communication terminal 110 displays a web page by executing a web browser, and when a moving image included in the displayed web page is selected (S303) The coordinate data of the web page is calculated and transmitted to the mobile communication server 120 (S305).

The mobile communication server 120 receives the coordinate data of the web page from the mobile communication terminal 110 and confirms the selected moving image on the web page of the mobile communication terminal 110 with the coordinate data of the web page, The socket library is called to communicate with the web server 140 that is posting (S307).

Then, the mobile communication server 120 hooks up the Http message output from the network driver 200 (S309), extracts the video access information data from the hooked Http message, searches for the extension corresponding to the moving image in the Http message , And extracts the video access information data including the retrieved video extensions. The video access information data includes a host address, a URL address, and cookie information, and may further include a referer header. The Http message output from the network driver 200 is most preferably an NDIS packet transmitted from the TCP / IP protocol driver 30 to the NDIS miniport driver 40.

Thereafter, the mobile communication server 120 transmits the extracted moving picture access information data to the mobile communication terminal 110 (S313).

The mobile communication terminal 110 receives the moving image access information data from the mobile communication server 120 and transmits the received moving image access information data to the moving image server 130 at step S315.

The video server 130 receives the video access information data from the mobile communication terminal 110 and requests the video server 140 to play the video corresponding to the video access information data at step S317, (S319).

Then, the moving picture server 130 converts the first extension of the received moving picture into a preset second extension (S321), and transmits the moving picture having the converted second extension to the mobile communication terminal 110 (S323 ). The first extension of the moving picture corresponds to one of flv, wmv, avi, asf, mpeg, mov, and rm.

The mobile communication terminal 110 receives the moving image having the second extension from the moving image server 130 and plays it on the screen (S325).
