## Background
TECHNICAL FIELD
The present invention relates to a data processing system using a dual monitor and controlling method of network system thereby, and more particularly, to a data processing system using a dual monitor and controlling method of network system thereby, which can process data by a computer using a dual monitor, on which separate contents are displayed respectively, as a display device.
BACKGROUND ART
In general, a data processing result of a computer is displayed on a monitor to show it to a user. The contents displayed on the monitor is converted and displayed into video signal through a video graphics adapter (hereinafter, called as “VGA”) controlled by a processor.
The user of the computer, occasionally, works while simultaneously loading several programs in one computer, for example, works with the computer in a state that a word processing program for word processing and a browser program for communication are loaded at the same time.
For example, when the user loads the word processing program, several web-browsers, a graphic editor program and others using the computer operated by an operating system of a window control type, links concerning the loaded programs are registered on a tray of a windows screen and a presently used program is displayed on the monitor.
However, generally, one computer is connected to one monitor. Thus, even though several programs are loaded, only one screen corresponding to the presently used program is displayed on the monitor. Therefore, when the user works confirming the processed result in respect with two or more programs at the same time, the user must select whenever the corresponding program on the window tray is needed, to pop up the needed program on the monitor.
To solve the problem, a windows 98 version having a multi-display function, which is an operating system developed by Microsoft Corporation, has been disclosed and widely used. The multi-display function means that two or more VGAs are connected to two monitors respectively and each monitor displays the processed result by the program set by the user.
The multi-display function can be very conveniently used in case that the user must work confirming the processed contents in respect with two or more programs at the same time after several programs are loaded. However, because two or more monitors are needed to use the multi-display function, a desk having a wide area is required.
Meanwhile, if the computer is connected to an Internet to connect to a specific Homepage through a web browser, information provided by the corresponding Homepage is displayed on the monitor.
However, most of the Homepages generally allows space for advertisement on a part of their own web page. Thus, the user must shut a window for the advertisement, which the user does not want, and enlarge or scroll the window, which displays the required information.
However, an advertiser wants to show the ad contents without regard to the user's intention because ad effects are decreased if the user shuts the window for the advertisement without seeing the ad contents. Conventionally, there are no systems and methods to satisfy both the user and the advertiser.

There are a LAN (Local Area Network) card, a modem and etc. as the communication device, and in the present invention, the communication device is connected to a network 7 through the LAN card 38.
The dual monitor 10 includes: a first monitor 12 serving as a main monitor for displaying the processed result of program, which a user uses presently; and a second monitor 14 mounted on the first monitor 12 and serving as an auxiliary monitor for displaying contents relating to or being different from the contents displayed on the first monitor 12.
The first and second monitors 12 and 14 are constructed integrally with each other by a common housing. The first and second monitors 12 and 14 may be constructed with a CRT (Cathode Ray Tube) display, a LCD (Liquid Crystal Display) panel, or other display elements. In consideration of the bulk, it is preferable to use the LCD panels for both of the monitors 12 and 14.
A digital camera 20 is mounted at the side of the second monitor 14 to input video information when it is used for a video telephone, and inputs video data to the processor 30 through a USB (Universal Serial Bus) port 44.
The video data processed and output from the processor 30 are input to the first and second monitors 12 and 14 through first and second video graphics adapters (VGAs) 46 and 48. In this embodiment of the present invention, a system constructed by two VGAs is disclosed, but it may be constructed with a dual port VGA having two output ports according to circumstances.
Video signals output through the first and second VGAs 46 and 48 are input to the first and second monitors 12 and 14 through first and second video cables 46a and 48a respectively. Because the first and second monitors 12 and 14 are formed integrally, their own video cable connecting terminals (D-sub connectors) are mounted adjacent to each other. Thus, the first and second monitors 12 and 14 may be connected to each other in such a manner that a plurality of lines for transmitting each video signal are integrated into one package and the first and second monitors 12 and 14 are connected with the first and second VGAs 46 and 48 by a video cable having a branch formed at both ends for connecting the first and second VGAs 46 and 48 and the first and second monitors 12 and 14.
The present invention having the above structure has an advantage that the number of the cables connected between the computer and the peripheral devices is decreased, and thereby the cables may be arranged in more convenience.
Moreover, the VGA can process two video signals like the conventional dual port VGA and has one D-sub connector serving as a video output port and having a plurality of pins for transmitting two video signals.
In the same way, also the dual monitor 10 has one D-sub connector serving as a video input port and having a plurality of pins for receiving two video signals, and the video cables connecting the video output port and the video input port are connected with each other by one video cable integrating the plurality of lines into one package for transmitting two video signals.
The present invention includes a broadcasting receiving part, i.e., a TV/R receiving part 50 for receiving TV/Radio broadcasting wave, such that one of the first and second monitors 12 and 14 may be used as a TV screen.
The TV/R receiving part 50 outputs TV video signal received by a control of the processor 30 through one of the first and second VGAs 46 and 48, and audio signal is output through a sound processing part 52, which will be described later, by the processor 30.
Therefore, the user can watch TV broadcasting through the second monitor 14 during using an Internet using a specific program through the first monitor 12, for example, a web browser. Especially, in case of receiving the radio broadcasting, because only audio signal is output, different programs may be processed through the first and second monitors 12 and 14.
It is possible that the dual monitor 10 has a broadcasting receiving part, which can receive TV/Radio broadcasting like the TV/R receiving part 50, the received broadcasting signals are transmitted to the processor 30 through a USB port 46, video signal of the broadcasting signals is output through one of the first and second VGAs 46 and 48, and audio signal is output through a speaker 22 through the sound processing part 52.
Furthermore, it is possible that the dual monitor 10 has a broadcasting receiving part, which can receive TV/Radio broadcasting like the TV/R receiving part 50, video signals are output through the first or second monitors 12 or 14 from the broadcasting receiving part, and audio signal is output through the speaker 22.
For this, the broadcasting receiving part must be controlled by the processor 30 in a change of broadcasting reception channels, a selection of the output monitor, or others, and convert and output video signals received from a tuner, which receives broadcasting signals, into video signals, which can be output through the first or second monitors 12 or 14.
The sound processing part 52, which processes audio signal and outputs into sound, is connected to the processor 30. The sound processing part 52 serves to output audio signal of broadcasting signals received by the TV/R receiving part 50, to produce audio signal and output through the speaker 22 when a multimedia is played by the processor 30, and to input sound through a microphone 24.
The speaker 22 connected to the sound processing part 52 basically has two speakers for stereo output. In case that the sound processing part 52 has a surround output function, the speaker 22 may have a plurality of speakers corresponding to the surround output function.
Additionally, the speaker 22 may be formed integrally with the housing having the dual monitor 10 to reduce an installation space.
A network constructed by using the data processing system using the dual monitor according to the present invention may be used for various purposes as follows.
First, in the present invention, a plurality of computers 2a, 2b and 2c using the dual monitor 10 as a display device form a network through the LAN cards 38 as shown in FIG. 2.
Here, dual monitors 3a, 3b and 3c connected to the plurality of computers 2a, 2b and 2c respectively include first monitors 4a, 4b and 4c and second monitors 5a, 5b and 5c respectively.
The computers 2a, 2b and 2c are connected to a network management server 1 through the LAN card 38 and form a local area network 7, and the network 7 is connected to the Internet. The characteristics in use according to the above construction will be described hereinafter.
In case of being connected to the Internet through the server 1, the processor 30 of the computer displays a web page of a Homepage connected by the web browser used by a user on the first monitor 12. The second monitor 14 displays additional information provided by the server 1, such as a message, ad information or others, and the additional information can be continuously displayed on the second monitor 14 without regard to the user's intention.
For this, the server 1 needs to secure a control right to the second monitor 14 through the computer processor 30 of the user and to control the use of the second monitor 14 by the user's manipulation.
The advertisement displayed on the second monitor 14 through the above method has an advantage that it is very profitable in securing advertisers, because having an excellent transmission effect in a server administrator position.
Moreover, after the LAN using the data processing system using the dual monitor according to the present invention, it may be used as an internal interactive system within a specific area, for example, a settlement system, and it will be described hereinafter.
Presently, settlement systems operated through the LAN take a method that, if there occurs matters to be settled while a reporter and a deciding officer do their desired work using their own computers, arrange the contents to be settled and transmit the contents to the deciding officer's computer to settle.
In case of the deciding officer, while the deciding officer is working using the dual monitor 10, a window containing the contents for settlement is popped up and displayed over the presently used window to respond to the demand of settlement.
Therefore, compared with the conventional method having a problem that the presently used window is covered with the window for settlement, because the system according to the present invention allows the deciding officer to settle through the second monitor 14 while working using the first monitor 12, the deciding officer can deal with the settlement while checking the contents presently used and the contents for settlement at the same time if the contents presently used and the contents for settlement are related with each other.
Furthermore, when at least two or more users perform jointly work with the same program using the plurality of computers 2a, 2b and 2c connected to the network 7, the contents for one user's work is displayed on the first monitor 12 and the contents for the other user's work is displayed on the second monitor 14, and thereby the users can jointly work while confirming the contents for his own work and the contents for the other party's work at the same time.
For example, when two users open the same document and input different contents to prepare a word processor file or a spreadsheet file, if the different data are input after the network controls the contents input by different users to be input into a single file, the users can input data while confirming a data input condition of the other party, thereby increasing the efficiency of work.
Furthermore, when a user interface provided by the program displayed on the first monitor 12, for example, a graphic user interface, is clicked with a mouse, the data processing system using the dual monitor according to the present invention displays a program connected to the corresponding user interface on the second monitor 14 (or to the contrary), such that a screen display area is enlarged by two monitors, thereby increasing the convenience in use of the computer.
Moreover, by using the digital camera 20 connected to the processor 30 of each of the computers 2a, 2b and 2c connected to the network 7 through the USB port 46, the data processing system according to the present invention may be used as the video communication system.
In other words, the user's picture captured with the digital camera mounted on the computer is transmitted to the other party's computer, and at the same time, the user's picture is displayed on one of his own first and second monitors, and the user's picture transmitted to the other party is displayed on the other monitor, and thereby the data processing system can be used as the video communication system.
