 [0027] The display device 10 (10-l to n) can be composed of an LED, an organic EL, an inorganic EL, a liquid crystal, plasma, or a CRT, and can be composed of a plurality of display media.

 Hereinafter, each configuration will be described in detail. The display device 10 (10-l to n) is any device that can display electronic data such as LED, organic EL, inorganic EL, liquid crystal, plasma, and CRT, and can be composed of one or more monitors. For example, a plurality of plasma displays can be connected or divided into a plurality of monitors as a hanging advertisement in a train. The monitor may be large or small.

 [0029] In each node 20, 30, an information distribution program is running in the communication control unit 21, and all the nodes 20, 30 can be connected to the information distribution P2P virtual network (FIG. 2). Each node 20, 30 can take various forms depending on the situation, such as a personal computer or a portable terminal.

 [0030] The software running on each node 20, 30 has the following functions, and the functions can be restricted at the software level. Also, a given node can be positioned as a knock-up node by extending the information storage period. Also, the zone 30 having a display device can be used as a so-called management terminal. In addition, as a usage mode, the nodes 20 and 30 are provided with communication units 28 and 38 having a messenger function, an e-mail function, and a Z or bulletin board function as communication tools, and the display device 10 is connected in an emergency. Information on the sword 30 can be connected to an arbitrary node 20 and displayed on the display device 10. In the P2P virtual network shown in Fig. 2, no communication is accepted from nodes other than the specified nodes 20-1 to 4 and 30-1 to 2.

[0031] The display control unit 22 displays information according to the time table (registered in the DB 27) set in the own node. Also, the illuminance of the display device 10 is automatically changed and displayed according to the time zone. [0032] DBs 27 and 37 store information and self-information in the P2P virtual network. Specifically, the time table, information (ID, IP address, etc.) that identifies the node for displaying information, and the contents of the information (still image (in the case of still image animation, motion information (time ), Video, text (in the case of text, characters 'color · size · display position on the monitor' action)), and information display position information indicating where to display on the monitor, and connection Member list of possible nodes (initial node is specified at the time of initial setup. The number of member lists can be limited to one or more) and information storage period (unlimited time backup) It can be used as a dedicated node), self-information (self-node ID, IP address, etc.), and information distribution history (information distribution history of self and other nodes).

 The distribution information registration units 23 and 33 have a distribution information registration function, and can register the information “when, where and what” in the DBs 27 and 37. In addition, when registering distribution information, the following two methods can be selected for uploading the information.

 (1) P2P upload: Update to the network from time to time using the mutual transmission / reception function.

 (2) Direct upload: Direct data upload to the designated advertisement node (s). Use in emergency situations.

 [0034] The information organizing units 24, 34 have an information organizing function, and periodically delete past information by setting the information storage period registered in the DBs 27, 37.

 [0035] The management units 25 and 35 have a management function, and manage sponsor information and billing information other than the information to be displayed. It also manages the customer master, etc., and manages the invoice management function (invoice management department 25—1, 35—1), sales management function (sales management department 25—2, 35—2), credit management function (credit management) Part 25—3, 35—3). In addition, it can be configured with multiple nodes in consideration of redundancy and stability. It also has an authentication function (authentication units 25-4, 35-4) that authenticates each node when it first connects to an existing P2P virtual network. In addition, it has a distribution history management function (distribution history management unit 25-5, 35-5) that manages the distribution history of information.

[0036] In addition, the time synchronization units 26 and 36 have a time synchronization function, and synchronize time between all connected nodes capable of communication. Display device 10 (10—l to n) by synchronizing time It is possible to synchronize the timing of switching the images displayed on the screen, or to display a single image by linking multiple screens of the display device (10-1) and (10-n).

[0037] The communication control units 21, 31 have a synchronization function between other nodes, and synchronize by transmitting / receiving information in the DBs 27, 37 periodically or at a predetermined timing based on the specifications of the P2P network. Here, when information is registered, it is possible to reduce unnecessary traffic by making a request to receive information to the required node. It also has a communication function and can use communication tools (messenger, e-mail, bulletin board, etc.) through the P2P network between each node. In addition, location information can be exchanged in conjunction with the GPS function of the mobile terminal.

 [0038] The communication medium 40 may be the Internet, a general public network, or any other communication means. Here, security communication such as VPN can be performed to ensure security.

 [0039] The P2P virtual network shown in FIG. 2 can be constructed as a virtual network to which the nodes running the above functions (programs) are connected. Here, subgroups can be formed by setting. In that case, the subgroup should be formed with nodes that are physically separated in the event of a disaster.
