PURPOSE:To realize a simultaneous display of the same data in remote different conference rooms, by transmitting the ID member of a data picture during conference and then reading and displaying automatically the data which is previously transmitted. CONSTITUTION:When a reading request signal 103 is given to a control part 8 from a conference room A, the corresponding ID number 107 is sent to a conference room B from a transmitting/receiving part 11. The part 8 refers to a correspondence table between the ID number in an input picture table storage part 9 and file addresses to obtain a file address 105 corresponding to the ID number. The address 105 is then fed to an input picture file part 6. The compressed picture signal read out of the part 6 is sent to an expanding part 5 via a memory 2 to be restored. This picture signal is written into the memory 2 and then displayed at a display part 3. On the other hand, the received picture corresponding to the received ID number is read out and displayed in the room B via a storage part 10 and a file 7. |
