- the original data acquisition unit 302 has a function of acquiring data to be transmitted to the image server 10 and finally distributed to each terminal device.
- the camera mechanism may have a function of capturing an image or acquiring data with a small external storage medium. If you can get data such as images and music.
- the identification information storage unit 307 and the data storage unit 309 do not have to be separate from each other. That is, the identification information and data stored in the identification information storage unit 307 and the data storage unit 309 may be stored in association with the same table.
- the data output unit 311 may have any form as long as it can output data. For example, it may be realized by a mechanism that displays an image or a moving image on a predetermined display unit, reproduces music from a speaker, or passes data to be subjected to some processing to another processing unit.
- the image server 10 receives image data as predetermined data from the terminal device 30 (here, the terminal device 30a) and assigns identification information will be described with reference to FIG. .
- the data acquisition unit 11 of the image server 10 acquires the image data acquired by the original data acquisition unit 302 of the terminal device 30a and transmitted from the data transmission unit 303 via the network 100 (S501). .
- the identification information generation unit 13 of the image server 10 generates identification information that can uniquely identify the acquired image data (S502). Then, the generated identification information is stored in the database 12 in association with the image data (S503). The identification information and the image data may be stored in a predetermined table in the database 12 in a one-to-one correspondence.
- the identification information transmission unit 14 of the image server 10 transmits the generated identification information to the terminal device 30a that is the transmission source of the image data (S504).
- the terminal device 30a receives the voice from the voice data distribution unit 21 of the PTT server 20 by the group call unit 301 and performs the group call (S601).
- the original data acquisition unit 302 of the terminal device 30a acquires image data (S602). Whatever the timing of group calls and image acquisition, it doesn't matter which way.
- the data transmission unit 303 of the terminal device 30a transmits the acquired image data to the data acquisition unit 11 of the image server 10 via the network 100 (S603).
- the identification information receiving unit 304 for image data of the terminal device 30a receives the identification information of the image server 10.
- the identification information of the image data transmitted from the transmission unit 14 is received (S604).
- the identification information transmitting unit 305 of the terminal device 30a transmits the identification information to the PTT server 20 via the network 100 (S605).
- the identification information distribution unit 22 of the PTT server 20 distributes identification information to all the terminal devices 30a, 30b, and 30 ⁇ via the network 100 (S606). Therefore, the identification information is also distributed to the terminal device 30a itself that transmitted the original data.
- the PTT server identification information receiving unit 306 of the terminal device 30b acquires the identification information distributed from the PTT server 20 (S607).
- the identification information search unit 310 of the terminal device 30b searches the identification information storage unit 307 based on the acquired identification information (S608). In the case of the first data acquisition, naturally the identification information is not retained. On the other hand, in the case of the second and subsequent data acquisition, since the previous identification information is already held, the identification information is not stored. Use it to output data.
- the data output unit 311 of the terminal device 30b outputs the data associated with the identification information. For example, it is displayed on a predetermined display unit. As described above, it is assumed that the identification information and the data are stored in association with each other. Overwriting may be performed when a predetermined period or amount is exceeded.
- the identification information transmission unit 305 of the terminal device 30 transmits the identification information to the image server 10 via the network 100 (S611).
- the identification information receiving unit 15 of the image server 10 receives the identification information (S612).
- the search unit 16 of the image servo 10 searches the database 12 based on the received identification information (S613).
- the identification information exists (S614ZYes) the image data associated with the identification information is acquired, and the data transmission unit 17 transmits the image data corresponding to the identification information to the requested terminal device 30b ( S615).
- the image server data acquisition unit 308 of the terminal device 30 acquires image data via the network 100 and stores it in the data storage unit 309 (S616). At this time, the image data is stored in association with the identification information.
- the data output unit 311 of the terminal device 30 outputs the acquired image data (S617). For example, it is displayed on a predetermined display unit. [0038] It should be noted that even with the terminal device 30b that has acquired the identification information, it is conceivable that the acquisition of data is deferred for reasons such as saving of data packet charges. Accordingly, the acquisition of identification information and the acquisition of data are processed only when the user issues separate instructions by pressing a predetermined button or the like, even if the terminal device 30b is automatically executed as a series of processes. Let's start.
- the user of the group call can refer to the image as well as the voice. For example, it is possible to proceed with work while looking at the photograph of the speaker's face at the meeting and confirming the site conditions at the construction site. This enables smooth communication using information other than voice.
- the processing for realizing the functions of the present system is executed by causing a computer constituting each device to read and execute a program for realizing the functions of the image sano 10, the PTT server 20 and the terminal device 30 in the present embodiment. You may do it. This will be briefly described.
- a computer 110 constituting the image server 10 includes an arithmetic processing unit 111 made up of an MPU or the like, a data storage unit 112 and a program storage unit 113 made up of a hard disk, etc., and an interface with the network 100.
- the recording medium 117 is, for example, a CD-ROM or a magneto-optical disk.
- a program 118 for controlling the operation of the computer 110 is provided in a state stored in the recording medium 117.
