In the network system according to this embodiment, the user is allowed to use the information communication terminal on condition that the service provider side connects to the key host managed and operated by the service provider. The provider side can reliably provide the service provided by the server operated by itself to the user. Since information linked to the TV screen viewed by the user can be broadcast, it is also possible to provide a viewer participation type TV service. In addition, it is possible to obtain information such as how much the user has watched TV by performing communication for each specific period, and user preference information such as what kind of program is often watched. It is also possible to obtain.

Particularly, according to the network system of this embodiment, the information communication terminal can be surely connected to the key host server. Since the information is also provided via the key host server, the relation between the information communication terminal and the key host server can be strengthened.

Next, a network system according to a second embodiment of the present invention will be described with reference to FIGS. 2 and 5. 2 is a schematic configuration diagram of the network system according to the present embodiment, and FIG. 5 is a flowchart diagram showing a processing procedure of the network system according to the present embodiment.

In FIG. 2, unlike FIG. 1, the information communication terminal 11 can directly transmit and receive with the hosts A and B. As shown in FIG. 2, the network system according to the second embodiment of the present invention includes an information communication terminal 11, a key host 12 that is always connected when the power of the information communication terminal 11 is turned on, and a broadcasting station, for example.

Associated with the transmitting / receiving unit 25. The other detailed configuration is almost the same as the configuration shown in FIG.

In the second network system shown in FIG. 2, the microcomputer section 20 of the information communication terminal 11 stores the address corresponding to the designated key host 12. When the power supply of the information communication terminal 11 is turned on as shown in step S11 of FIG. 5, the key host 12 is automatically logged in as shown in step S12.

In step S13, the key host 12
Compares the registrant data in the microcomputer section 12b with the identification ID of the mobile communication terminal 11 and determines whether or not they match.
The license is determined to be licensed or unusable, and the resulting availability signal is transmitted to the information communication terminal 11.

The information communication terminal 11 receives the enable / disable signal, and the microcomputer section 20 determines which signal it is. If the signal is a license signal in step S15, the key host 12 address lock in the microcomputer section 20 is performed. After releasing, the information communication terminal 11 is put into the operation standby state. In the case of the use refusal signal, the microcomputer unit 20 controls the information communication terminal 11 in the stopped state in step S14. Even when neither the use permission signal nor the use refusal signal is received, the microcomputer unit 20 controls the information communication terminal 11 in the stopped state. These states are displayed on the liquid crystal panel of the information communication terminal 11, for example, and the user can confirm the situation.

From the operation standby state after the information communication terminal 11 receives the communication permission, when the user requests the key host 12 to receive the broadcast in step S16, the authentication confirmation is performed in step S17. After updating the registrant list, in step S18, the transmission / reception unit 25 of the mobile communication terminal 11 makes the host A1

For example, next, in step S19, when the information communication terminal 11 receives the communication permission and the user requests, for example, music information from the operation standby state,
The transmitting / receiving unit 25 can directly access the host B 14 and directly obtain the music information from the modem unit 14a. In the case of a broadcast reception request, in the information communication terminal 11, the broadcast information is obtained by the transmission / reception unit 25, and when the input is an analog video signal, the signal is processed by the video chroma processing unit and separated into RGB signals. , Is converted into a digital value in the A / D converter, adjusted to a predetermined level in the LCD controller, and input to the liquid crystal panel as a panel drive signal corresponding to the video signal.

Further, when the input is an RGB digital video signal, it is directly input to the LCD controller section, is adjusted to a predetermined level by the LCD controller section, and is a liquid crystal panel as a panel signal corresponding to the video signal. Is input (see FIG. 3). In case of music information request, first
Similar to the case of the network system according to the embodiment of the present invention, the signal received by the modem unit 22 is sent to the mail / Internet processing unit, converted into a digital value, stored in the control unit, and listens to music through a speaker as appropriate. be able to.

In the network system according to the present embodiment, not only the transmission and reception of the permission signal between the information communication terminal 11 and the key host 12 but also the key host 12 is requested by the information communication terminal 11 to be sent by the information communication terminal 11 to the key host 12. It is also possible to control / manage, and to perform access control and forced access of the information communication terminal 11 from the key host 12. For example, the user can use the information communication terminal 11 to access the key host 12 and perform channel reservation information.

When the information communication terminal 11 is licensed from the key host 12 when the power is turned on, the channel reservation information is transmitted to the key host 12 so that the information is registered in the microcomputer section 12b. In this case, the key host 12 sends the channel reservation information to the information communication terminal 1 at the reserved time.
Send to 1. The microcomputer unit 20 receives the data and sets the channel.

According to the network system of this embodiment, it is possible to receive information from another server after the key host server has been authenticated by the information communication terminal. Therefore, the data capacity handled by the key host server can be reduced. Further, since various information can be exchanged with other servers without going through the key host server, there are few restrictions on acquisition of information.

Next, a network system according to the third embodiment of the present invention will be described with reference to FIG.
The configuration of the network system is similar to that shown in FIG. 1 (or FIG. 2) and FIG. Description will be made with reference to FIGS. 1 and 3 as appropriate. In the network system according to this embodiment, it is possible to force the information communication terminal 1 to perform advertisement viewing from the key host 2.

As shown in FIG. 6, when the power of the information communication terminal 1 is turned on in step S21, step S2 is performed.
As shown in 2, the key host 2 is automatically logged in.
In step S23, the microcomputer 2b of the key host 2
After collating the registrant data, transmits a use permission signal (step S25) or an unusable signal (step S24) to the information communication terminal 1. In the present embodiment, in step S25, a specific advertisement signal is simultaneously transmitted together with the use permission signal. As shown in step S26, in the information communication terminal 1, the request for other information is prohibited during the output (reproduction) period of the advertisement signal, and the information request is permitted only after the end of viewing the advertisement. That is, if the advertisement is not viewed, the process proceeds to step S24, and the operation of the terminal is stopped. If the advertisement is viewed, step S27
Then, the information communication terminal 1 enters the standby state. After that, for example, the process proceeds to step S6 of FIG. 4, and the operation is performed according to the following steps.

According to the network system of the present embodiment, it is possible for a user who acquires information using an information communication terminal to view the advertisement information which the service provider or its sponsor wants to provide to the user.
In return, if the sponsor can be charged for the information provision, the information provision fee and the information communication terminal fee can be reduced.

In order to monitor whether or not the advertisement has been viewed, for example, the key host 2 monitors whether or not the power source of the information communication terminal 1 is turned off during the advertisement time, and if it is turned off, the information is displayed. The communication terminal 1 may be controlled to be in an inactive state, inactive for a certain period of time, or the contract may be canceled by deleting the registrant.

Also, when the information communication terminal 1 starts up the Internet, or from the TV to the video (VTR), from the video to the TV, from the TV to the Internet, etc., the information is displayed so that the advertisement is displayed by logging into the designated host every time the mode is switched. The communication terminal 1 may be controlled. When switching modes, the microcomputer issues an instruction to automatically log in to the specified host address of the microcomputer. Further, when the key host 2 is regularly connected, the advertisement may be displayed in a small window each time. In addition, this small window can be deleted by a predetermined action such as clicking with a mouse, or it is set to automatically disappear after a predetermined time has elapsed. You can keep it. Further, at that time, when it is not desired to see the advertisement, it may be possible to set the information communication terminal 1 so that the operation state can be maintained by setting the advertisement to be collectively viewed later. .

When a TV having a horizontally wide screen is used as the information communication terminal 1, a normal screen such as a video is placed near the center or one of the sides, and the vacant side has a certain period. Send advertisements and information, and display advertisements and information only during that period or continuously thereafter, or send advertisements and information to the information communication terminal 1 when the service provider wants to send the information and information. It can also be displayed on the communication terminal 1.

Similarly, when the Internet or electronic mail processing is performed using a TV having a horizontally wide screen, the main screen is displayed either on the center of the screen or on one side of the screen, and a predetermined side is displayed on the empty side. For each period, the service provider sends advertisements and information etc. to display the advertisement information etc. only at that time or continuously, and sends advertisements and information etc. at the time when the service provider wants to send advertisements and information etc. Advertisements and information can be displayed on the display screen of the terminal 1.

As described above, by configuring a system in which a specific host controls the information communication terminal 1 for a specific period, it becomes possible to build a network system as a new business. The following methods can be used as request information from the information communication terminal 1 and a specific control method for stopping the operation of the information communication terminal 1.

For example, no video signal is sent, no signal is sent from the LCD controller to the display panel, no backlight is turned on, no power is supplied to the LCD controller, no power supply or video signal is switched by the switch, no sync signal is sent. And the like, and the method is not limited to the method described in the network system according to the present embodiment. Further, the transmission and reception of the permission signal and the advertisement signal between the information communication terminal 1 and the key host 2 can be carried out not only when the power is turned on, but also by a method in which communication is carried out periodically such as once an hour.

Since the information linked to the TV screen viewed by the user can be flowed, it is possible to propose a viewer participation type TV, and by communicating at a specific period, information about the time when the user used the TV and how. You can also get information about what programs you are watching. The service provider can send not only advertisements but also questionnaires, quizzes, etc., and can build a TV that allows viewers to participate. In addition, pay
It can also be used for pay broadcasting such as per view, and can also be used as a keyword for descrambling. Furthermore, it is possible to easily manage information selection according to the user's request. Although the present invention has been described above with reference to the embodiments, the present invention is not limited thereto. It will be apparent to those skilled in the art that other various modifications, improvements, and combinations can be made.
