Abstract
A multipoint teleconference system dispensing with an MCU, in which terminals are connected into a loop configuration through an ISDN in such a way that each terminal is coupled with each of the adjacent terminals by a single B channel. Thus, a communication frame is revolved through a looped communication channel. Each terminal renews video data which is contained in an allotted area within the received communication frame and which was transmitted by the terminal itself, and it relays the resulting communication frame to the next terminal.
