摘要

PROBLEM TO BE SOLVED: To provide a multimedia data transfer system capable of increasing the efficiency of operation and transmitting/receiving data irrespective of a place. SOLUTION: When a cooperation operation of multimedia applications arranged in personal computers 20 and 40 and extension telephone sets 13 and 33 is performed, PBXs 10 and 30 store cooperation information in databases 11 and 31. The PBXs 10 and 30 check the presence or absence of the personal computers 20 and 40 where the cooperation operation is completed and the state (during starting/during using) of the multimedia application in the databases 11 and 13. When they are matched with each other, the PBXs 10 and 30 start communication in the multimedia applications arranged in the personal computers 20 and 40. COPYRIGHT: (C)2005,JPO&NCIPI
