QUALITY IMPROVING METHOD IN MULTIPOINT COMMUNICATION AND MULTIPOINT COMMUNICATION TERMINAL, AND QUALITY IMPROVING PROGRAM IN INTER-MULTIPOINT COMMUNICATION

摘要

PROBLEM TO BE SOLVED: To improve communication quality by reproducing video images and sounds to be transmitted from multiple points, without being influenced by the delay time in the transmission line.;SOLUTION: Receiving units 110, 210, 310 of each of terminals 100, 200, 300 are provided with variable delay means 121 and 122, 221 and 222, 321 and 322, respectively. The delay time of each of the variable delay means is set at a proper value, corresponding to the delay time of the signal from an opposite-party device to match reproduction timing of signals transmitted from a plurality of terminals. Thus, the communication quality is improved.;COPYRIGHT: (C)2005,JPO&NCIPI
