- step S622 if the information of the information transmission device that is the connection request partner does not exist in the accumulated propagation information (step S622: No), the standby state in step S621 is entered. If the information of the connection partner's information transfer device exists in the received propagation information (step S622: Yes), the authentication function information on the propagation information is used to establish an ad hoc connection, and the connected information transfer device ( Reply information is received from any of 100A ⁇ : 100C) (step S623).
- step S624 If the received reply information cannot be propagated in step S624 (step S6 24: No), and if it is 0 or less in step S626 (step S626: No), no more reply information is sent. Since the propagation is not performed, the reply information is deleted (step S628), and it waits for a connection request from another information transmission device (from 100A to 100C) in step S621.
- FIG. 7-1 is a flowchart showing a procedure of processing performed by the safety information server when information transmitted from the information transmission device is received.
- step S701 it is determined whether or not reply information from the information transmission apparatus (any one of 100A to 100C) has been received.
- step S701 it waits for reception of reply information, and if it is received (step S701: Yes), it is next determined whether or not GPS information is included in the reply information (step S702).
- Step S702 If GPS information is included in the reply information in Step S702 (Step S702: Yes), the information transmission device (100A ⁇ : 100C) is recorded from the GPS information (Step S703). Then, the process proceeds to the process of step S704. If the GPS information is not included in the reply information (step S702: No), first, the reply information or the call location information is transmitted to the safety confirmation requester (step S704) Subsequently, the record ID of the propagation information corresponding to the return information is retrieved from the propagation information that has been created in response to the safety request so far, and is deleted (step S705). Use email or telephone.
- FIG. 7_2 is a chart showing an example of a propagation information table after safety confirmation.
- Chart 720 if the propagation information corresponding to the reply information is the record ID 000011 shown in Figure 4-2, the propagation information of the record ID 000011 is deleted and the record is recorded by receiving the reply information in step S701. It has only the propagation information of ID000012.
- transmission end information including an instruction to delete the propagation information of the record ID searched for to the broadcasting station is transmitted (step S706), and the series of processing ends.
- the broadcasting equipment 130 of the broadcasting station ends the regular broadcast of the propagation information of the completed record, and the information transmission devices 100A to 100C are terminated from the broadcasting network 140. Broadcast propagation end information of the record that ended.
- each user can use the transmission method for an unspecified number of broadcast waves. Only information related to can be acquired quickly. In addition, even when the user who receives the broadcast wave is located in an environment where connection with the communication network is impossible, the connection with the communication network is secured by performing propagation between the information transmission devices. Reply information can be transmitted to a desired address via the information transmission device.
- the information transmission method described in the present embodiment can be realized by executing a program prepared in advance by a computer provided in information transmission devices 100A to 100C and the information transmission device.
- This program is recorded on a computer-readable recording medium such as a hard disk, flexible disk, CD-ROM, MO, or DVD, and is executed by being read from the recording medium by the computer.
- this program may be a transmission medium that can be distributed through a network such as the Internet.
- the information transmission device, the information transmission device, and the information transmission method according to the present invention are useful for applications in which a large number of receiver terminals simultaneously receive content via a broadcast network. Suitable for communications in digital broadcasting environments such as digital broadcasting and terrestrial digital broadcasting.
