<p>PURPOSE:To obtain an audio/video communication system for synchronizing audios and images on the side of an incoming terminal. CONSTITUTION:The audios are digitally coded by an audio coding circuit 2 and when information is stored to fill an audio information area, a virtual channel identifier is imparted by a first cell circuit 5. The videos are digitally coded by a video coding circuit 3 and when information is stored to fill a video information area, a virtual channel identifier is imparted by a second cell making circuit 6. After the information is made into cells, they are transmitted through a cell multiplexing circuit 7 and an asynchronous transfer mode communication network 8 to a cell multiplexing separator circuit 11 and separated into audio information and video information. The video information is temporarily stored by a second buffer circuit 13. Thus, the video information synchronized with the audio information can be obtained.</p> |
