The present invention relates to a multiple control system of information carriers.

In general, different buildings are set up for each floor in a multi-community building.

However, it is not easy to control each layer set to different areas as described above through one control device.

As a specific example,

[One]. In general hospitals, the hospital's business guidance, floor guidance, medical knowledge, patient and medical staff calls are all made through a separate voice system (one microphone and multiple speakers) or by installing information boards on each floor.

[2]. The airport provides information such as flight departure and arrival information, signing system, monitoring system, advertisement, etc., but the departure and arrival information of the flight is made through a large information desk installed on each floor and the information of the information desk Upgrade to a separate terminal.

In addition, the information of the monitoring system or advertisement of the airport is also implemented by the control of the terminal connected to the monitor or the insertion of the physical image tape in the state in which the two-way is not implemented.

In other words, the information of the conventional airport has the disadvantage that the information output of the video or text is executed from the operation of the individual terminal, the system construction cost is excessive, and the upgrade of the information is limited.

In addition, the above problems are problems that appear together in schools, banks, etc., due to this problem, the user who wants to be guided by the discontinuity is not provided with faster delivery of information.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, one control server transmits the control command and the scheduling of the information carrier to a plurality of clients in different locations and the transmitted control command and In accordance with the scheduling, a plurality of clients operate an information medium (e.g., plasma display panel, LCD, projection TV, video, etc.) connected to a serial port, and report the operation status to a control server. The purpose is to provide a multi-control system of information media that improves the efficiency of system operation by managing multiple information media located in different spaces while eliminating the inconvenience of connecting separate control devices to the devices. .

The client receives his IP address from the integrated management server at the time of his power on and recognizes the IP information of the integrated management server so that the control of the information sale and the scheduling thereof can be smoothly performed.

That is, when each client is powered on while the integrated management server and a plurality of clients are connected to each other by a local area network (LAN) or the Internet, the client operates as a DHCP (Dynamic Host Configuration Protocol) client module. In addition, the integrated management server also performs its operation as a DHCP server module.

At this time, the client attempts to connect with the integrated management server through a specific protocol, that is, "HTTP Protocol" or "IBB (Interactive Bulletin Board) Protocol", and the integrated management server gives the client an IP address and performs integrated management. By allowing the client to recognize the server's own IP address information, the connection between the integrated management server and the client for multiple control of the information carrier is maintained.

Here, the IBB protocol is a server / client control protocol developed by the applicant of the present application, which refers to a protocol for allowing a server to transmit or receive a script command sent to a client or data sent by the client to the server over TCP / IP. It is most preferable to apply the above-described IBB protocol in a media multiple control system.

In other words, the integrated management server monitors a plurality of clients or manages a client's text character script or a management tool or schedule of the script or a cover page and a message window of a web page in an integrated environment,

The client controls the information medium connected to the serial port through a control command or schedule of the integrated management server, integrated information via the Internet, web browsing (eg HTML 4.0, Java script 1.3, animated GIF, JPEG, AU, wave etc), status reporting, and the DHCP client module.

Here, the scheduling means that the integrated management server designates the operation of the client in advance and desired. It is the ability to start at the end of time and end at the desired time, and you can assign the same action to multiple clients, or even different actions. To implement this scheduling, we introduce the concept of script, which is generally called a script. It refers to a structure that defines the basic operations and creates a new operation by adjusting the number or timing of the operations.

On the other hand, the client recognition unit 10 by the client detector 11 and the client detector 11 for detecting the connection state of the client 200 when the standby socket operation of the integrated management server 100 as shown in FIG.
