Abstract

PURPOSE:To proceed a conference even when the privacy call state is suddenly reached during the conference by providing a video reproduction circuit able to reproduce a video signal of a preset predetermined pattern and providing a privacy call mode setting notice means to the television conference equipment. CONSTITUTION:When a conference participant operates a conference mode operation circuit 9 to set the conference mode into the 'privacy call' mode, a control signal is inputted from the conference mode operation circuit 9 to a control circuit 12, which detects the 'privacy call' mode to switch a voice changeover circuit 13 thereby connecting a voice output terminal 15 and a termination resistor 14. Moreover, a video changeover circuit 8 is switched simultaneously to output a video signal of a preset predetermined pattern being an output of a video reproduction circuit 7 from the video changeover circuit 8 thereby sending the video signal to a transmission line from a video output terminal 10. Thus, the opposite party confirms the privacy call mode because a video appears on a receiver in the 'privacy call' mode, then the conference is proceeded without confusion even when the 'privacy call' mode is suddenly selected during the conference.
