In such a situation, a website established on the Internet, that is, a server of an information provider provides a banner advertisement together with information. The banner advertisement is a hypertext markup language tag (Hypertex).
When the user clicks on the banner advertisement, the user is taken to the linked advertiser's website.

[0004] Since such a banner advertisement causes a decrease in connection speed including an image, the user does not actively use the banner advertisement. Therefore, a user who clicks on the banner advertisement is called a "cyber money". Advertising techniques have been developed to increase the utilization rate of banner advertisements by giving the prize of saving.

[0005] On the other hand, a so-called TV-type advertisement, in which an advertisement is displayed by using a waiting time until a user moves from one site to another site, is newly presented.

[0006] Further, in the information presentation system in the electronic network disclosed in Japanese Patent Application Laid-Open No. 10-254966, there is a measure for eliminating time consumption in which the user has to wait unconditionally until the content data can be actually viewed. is suggesting. Referring to FIG. 1, a user terminal device 1 includes a communication control unit 11 that acquires content data from a network (NW) and an advertisement acquisition unit 1 that acquires advertisement data.

The microprocessor 33 outputs the information data and the advertisement data to the video card 32 together with an area for displaying the advertisement data (hereinafter, referred to as a first area) and an area for displaying the information data (hereinafter, the second area). ) Is output to the video card 32. At this time, the microprocessor 33 can display the advertisement data in various patterns as shown in FIG. 4, display the advertisement data in a peripheral area (first area) of the screen, and display information in a central area (second area) of the screen. It is desirable to specify a display area to display data.

The video card 32 combines information data and advertisement data in one screen unit according to the area designation signal, converts this into color signals (R, G, B), and
0 to the video signal processing unit 73, and the video signal processing unit 73 amplifies the combined color signal to an appropriate level, and then
80. The video card 32 outputs the horizontal synchronization signal and the vertical synchronization signal to the microprocessor 71 of the monitor 70. The microprocessor 71 receives the horizontal synchronizing signal and the vertical synchronizing signal, reads out the monitor management information stored in the memory 74 in order to perform a control operation for displaying the advertisement data on the monitor screen, and then performs a smoothing circuit ( (Not shown). Accordingly, on the monitor screen, the advertisement data is displayed in the first area designated by the microprocessor 33, and at the same time, the information data is displayed in the second area.

When the user deletes or modifies the application program stored in the hard disk 34, the advertisement data is not displayed on the monitor, and the microprocessor 71 of the monitor main body 70 inputs and outputs the contracted signal through the USB device 40. Then, it is checked whether the application program is normally executed in the computer main body 30. That is, the microprocessor 71 periodically outputs a check request signal through the USB device 40, and recognizes that the application program is normally executed if a response signal is input from the microprocessor 33 in response to the check request signal. In addition, when the microprocessor 33 periodically outputs the check signal, the application program recognizes that the application program is normally executed. The USB device 40 is connected to the computer main body 30 and peripheral devices (the printer 5).
0, scanner 60, etc.), including existing features that support communication protocols for exchanging data and signals between them.

On the other hand, the computer main body 30 and the monitor main body 70 do not use the USB device 40 and use DDC / CI (Display D / CI).
ata Channel / CI), DDC2B +, RS232C, etc.
And the microprocessor 71 input and output the contracted signal, and directly transmit the horizontal synchronization signal and the vertical synchronization signal output from the video card 32 to the microprocessor 71.

When the Internet connection unit 31 is connected to the Internet 25, information data and advertisement data are simultaneously displayed on the monitor. In this state, the user can read the user program (Hangul, (Lotus, Excel, etc.), the advertisement data will be continuously displayed on the monitor screen. That is, the microprocessor 33 outputs the information data of the user program and the advertisement data to the video card 32 and an area designating signal for displaying the advertisement data and the information data of the user program in the first area and the second area. To the video card 32. Accordingly, the video card 32 combines the information data of the user program and the advertisement data into one screen unit according to the area designation signal, converts the combined data into color signals, and outputs the color signals to the video signal processing unit 73. The unit 73 applies the synthesized color signal to the CRT 80.

Thus, the server 2 is located in the second area of the monitor.
When the information data supplied from 0 or the information data of the user program is revealed, the advertisement data downloaded from the server 20 and updated on the hard disk 34 is continuously displayed on the first area of the monitor.

The advertisement data displayed on the first area of the monitor can be displayed in various patterns depending on the portion designated by the microprocessor 33 as shown in FIG. For example, as shown in FIG. 4A, the microprocessor 33 sends an area designation signal for displaying advertisement data in the lower right part (R1) of the monitor screen and displaying information data in the other area (R2). In the case of outputting to 32, the advertisement data is displayed on the monitor together with the information data. In FIG. 4B, the microprocessor 33 displays the advertisement data in the lower left portion (R1) of the monitor screen, and the other regions (R
FIG. 4C shows a case where the microprocessor 33 displays the advertisement data in the edge area (R1) of the monitor screen and outputs the advertisement data to the other areas (2).

FIG. 4 (G) shows a case where the microprocessor 33 displays the advertisement data on the right side (R1) of the monitor screen while outputting an area designation signal for displaying information data in the other area (R2). This is a case where an area designation signal for displaying information data is output in the area (R2) of FIG.
(H) shows the lower row of the monitor screen by the microprocessor 33.
FIG. 4 (I) shows a case where the advertisement data is displayed on (R1) and an area designation signal for displaying information data is output on the other area (R2). This corresponds to the case where advertisement data is displayed in R1) and an area designation signal for displaying information data in the other area (R2) is output.

As described above, the microprocessor 33
When the application program of the hard disk 34 is normally executed, the CRT 80 maintains the active state to display both the information data and the advertisement data. When the advertisement data is not displayed on the monitor screen by deleting or transforming the CRT, the CRT 80 is automatically changed to the inactive state.

For this reason, it is checked in the computer main body 30 whether the application program is operating normally. There are two types of such check methods. First, the microprocessor 71 of the monitor body 70 periodically outputs a check request signal to the microprocessor 33 of the computer body 30 through the USB device 40, and the microprocessor 33 to which the check request signal is input has a normal application program. An operation response signal is output to the microprocessor 71 through the USB device 40. Accordingly, the microprocessor 33 continues to perform the operation of displaying the advertisement data on the monitor screen during the normal operation, and if there is no response signal, the protection mode (protect m).
Proceed to ode).

That is, as shown in FIG. 6, when the power is supplied, the microprocessor 33
After the computer operating system (OS) program is started and booted (S101), an application program of the hard disk 34 is executed to try to connect to the server 20 (S1).
02).

Subsequently, if the connection with the server 20 succeeds, the microprocessor 33 starts the first area (R) of the monitor screen.
1) Display the advertisement data in the second area (R2) of the monitor screen
After transmitting an area designation signal for displaying information data to the video card 32 (S103), the hard disk 34
Is transmitted to the video card 32 which is updated to
(S104). Then, the microprocessor 33 is a USB
It is determined whether a check request signal is input from the microprocessor 71 through the device 40 (S105).
If the determination result check request signal of step (S105) is not input, the operation returns to step (S104) to continuously perform the operation of transmitting the advertisement data, while the determination result check request signal of step (S105) is input. Is hard disk 3
The execution state of the application program No. 4 is checked (S106).
Subsequently, the microprocessor 33 determines whether the application program is being executed (S107). If the application program is being executed, the microprocessor 33 outputs a response signal to the microprocessor 71 through the USB device 40 (S108). If the program is not running, the program proceeds to the protection mode to restrict the user from using the computer (S10).
9).

The operation of the monitor body 70 related to the operation of the microprocessor 33 will be described with reference to FIG.

First, the microprocessor 71 receives the horizontal synchronizing signal and the vertical synchronizing signal from the video card 32, reads out the monitor management information from the memory 74, and controls the smoothing circuit. At this time, the video signal processing unit 74 By inputting a color signal in which the advertisement signal and the advertisement data are combined, amplifying the color signal to an appropriate level, and applying the amplified signal to the CRT 80, the first
The advertisement data is displayed in the area (R1) and the second area (R2)
Is displayed (S201). Subsequently, the microprocessor 71 determines whether the preset time has elapsed (S202). If the result of the determination is that the preset time has not elapsed, the microprocessor 71 performs a step of continuously displaying the advertisement data (S201). On the other hand, if the set time has elapsed, a check request signal for checking whether the application program is running is output to the microprocessor 33 through the USB device 40 (S
203). Thereafter, it is determined whether or not a response signal indicating that the application program is being executed is input from the microprocessor 33 (S204). If there is a response signal as a result of the determination in the step (S204), the microprocessor 71 continues to control the display operation on the monitor. At this time, the video signal processing unit 73 receives the synthesized color signal, amplifies it to an appropriate level, and then controls the CRT 80. To display the advertising data together with the information data on the monitor screen (S205).
If there is no response signal in (S204), the process proceeds to the protection mode.

When the application program operates normally, the microprocessor 33 periodically outputs a check signal through the USB device 40 (the microprocessor 71 of the monitor body 70 does not output a check request signal). Microprocessor 71 displays the advertisement data on the monitor screen while the check signal is input, and proceeds to the protection mode if the check signal is not input.

When the microprocessor 71 shifts from the normal mode to the protection mode, that is, when the display state of the CRT 80 is changed to the inactive state, a specific OSD character (for example, "unusable") is displayed on almost all areas of the monitor screen. A first method for intentionally displaying ")" and a second method for displaying a muting signal on a monitor screen can be selected.

First, the first method will be described.
If you proceed to the protection mode under the state where information data and advertisement data are divided and displayed together (normal mode) as in
The microprocessor 71 outputs a mode control signal for switching to the protection mode to the OSD processing unit 72,
The processing unit 72 is set in advance in response to the mode control signal.
An OSD character signal is output, and the OSD character signal is applied to the CRT 80 through the video signal processing unit 73. As a result, as shown in FIG. 5B, the screen is occupied in a state occupying most of the area of the screen, and changes to an inactive state in which the information data already displayed is interrupted.

In the second method, the microprocessor 71 outputs a mode control signal for switching to the protection mode to the DPMS driving unit 75, and the DPMS driving unit 72 actually responds to the mode control signal in response to the video control signal. A standby (Stand-By) mode or a suspend (Suspend) mode in which one of the horizontal synchronization signal and the vertical synchronization signal of the screen normally output from the card 32 is intentionally applied to the CRT 80.
Take action to switch to mode. That is, in the protection mode, the DPMS driving unit 72 switches to the standby mode in which the application of the horizontal synchronization signal is suspended instead of allowing the CRT 80 to apply the vertical synchronization signal, or instead of allowing the CRT 80 to apply the horizontal flag signal to the CRT 80. The mode is switched to the suspend mode in which the application of the vertical synchronization signal is suspended, and accordingly, as shown in FIG. 5A, the information data and the advertisement data are divided and displayed together as shown in FIG. The screen changes to an inactive state in which a mute signal is displayed on the screen and the contents of the information data cannot be recognized.

On the other hand, even when the user executes a user program (Hangul, Lotus, Excel, etc.) stored in the hard disk 34 of the auxiliary storage device without connecting to the Internet, the advertisement data is kept on one side of the monitor screen. The advertisement data is displayed, but the last updated advertisement data is displayed on the hard disk 34 and continues. To explain this, when a user program stored in the hard disk 34 is executed in a booting state by a computer operating system (OS) at the time of power supply,
According to one of the patterns shown in FIG. 4, advertisement data supplied from the server 20 and updated on the hard disk 74 is displayed in the first area of the monitor screen, and at the same time, the first area of the monitor screen is displayed. Information data corresponding to the user program is displayed in two areas. In this state, the monitor main body 70 checks whether the application program is normally executed by the computer main body 30, and checks whether a response signal corresponding to the check request signal output periodically is input as described above. Or a check signal periodically inputted from the computer main body 30 is inspected to make a judgment. As a result of such a check, if the application program is deleted or deformed, it is controlled by the microprocessor 71.
The OSD processing unit 72 or the DPMS driving unit 75 is operated, and FIG.
As shown in (B) or (C), the operation proceeds to the protection mode, and the CRT 80 is switched to the inactive state.

[0043]

As described above, the Internet advertisement screen display device according to the present invention executes the application program stored in the hard disk of the computer main unit, and outputs information data or data supplied from the server while connected to the Internet. The advertisement data is always displayed on one side of the monitor screen together with the information data of the user program. Even when the user program is executed without connecting to the Internet, the last updated advertisement data is always displayed on one side of the screen.

The monitor periodically checks whether the application program of the computer is operating normally. If the application program is intentionally damaged and the advertisement data is not displayed on the monitor, the protection is automatically performed. Enter a mode to display a specific OSD character, or suspend the application of one of the vertical and horizontal synchronization signals to the monitor, display the mute signal on the monitor screen, and use the monitor forcibly.
