Document Type and Number:
Japanese Patent JP4858441
Kind Code:
B2
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.
