Abstract
A terminal device (30a) transmits image data to an image server (10) (S603). The image server generates the identification information of the image data. A PTT server (20) distributes the generated identification information to all terminal devices (30a -30n). If the terminal device does not hold the distributed identification information, the identification information is transmitted to the image server (S611). The image server transmits image data associated with the received identification information to the terminal device as the identification information transmission source (S615). Upon receiving the image data, the terminal device outputs the terminal device (S617). This allows to exchange data except voice data.
Claims21
A broadcasting system characterized by comprising:
- a server;
- and
- a plurality of terminal devices connected to said server via a network,
- each of said terminal devices comprising:
- a terminal-side data acquisition unit which acquires, from said server, data, except voice data, transmitted from another terminal device;
- and
- a data output unit which outputs the data acquired by said terminal-side data acquisition unit.
A server apparatus characterized by comprising:
- a data acquisition unit which acquires data, except voice data, transmitted from one of a plurality of terminal devices connected via a network;
- an identification information generation unit which generates identification information of the data acquired by said data acquisition unit;
- an identification information distribution unit which distributes the identification information generated by said identification information generation unit to each of the terminal devices;
- an identification information reception unit which receives identification information transmitted from the terminal device when the terminal device does not hold the identification information;
- and
- a data transmission unit which transmits data associated with the identification information received by said identification information reception unit to the terminal device as a transmission source of the identification information.
A terminal device characterized by comprising:
- a data acquisition unit which acquired, from a server connected via a network, data, except voice data, transmitted from another terminal device;
- and
- a data output unit which outputs the data acquired by said data acquisition unit.
A data transmission method characterized by comprising the steps of:
- causing one terminal device to acquire, from a server connected via a network, data, except voice data, transmitted from another terminal device;
- and
- outputting the acquired data.
A program characterized by causing a computer included in a server to execute:
- a process of acquiring data, except voice data, transmitted from one of a plurality of terminal devices connected via a network;
- a process of generating identification information of the acquired data;
- a process of distributing the generated identification information to each of the terminal devices;
- a process of receiving the identification information transmitted from the terminal device when the terminal device does not hold the identification information;
- and
- a process of transmitting data associated with the received identification information to the terminal device as a transmission source of the identification information.
A program characterized by causing a computer included in a terminal device to execute:
- a process of acquiring, from a server connected via a network, data, except voice data, transmitted from another terminal device;
- and
- a process of outputting the acquired data.
