ABSTRACT:
An apparatus and a method for controlling a plurality of sub monitors in a video communication system in which the same signal from a host computer or a video tape recording/reproducing device is displayed on screens of the sub monitors and a main monitor to which the sub monitors are connected in series. The main monitor generates control data in response to an external sub monitor control signal to set up a desired one of the sub monitors. A plurality of communication devices are included respectively in the sub monitors, for serially transferring the control data from the main monitor to the sub monitors and response data from the sub monitors to the main monitor. A plurality of microcomputers are connected respectively to the communication devices, for setting up a corresponding one of the sub monitors in response to the control data from the main monitor when the control data from the main monitor is for the control of the corresponding sub monitor and transferring the control data from the main monitor to the subsequent sub monitor when the control data from the main monitor is not for the control of the corresponding sub monitor. According to the present invention, the main monitor can control the plurality of sub monitors using the communication devices therein and a program for the control thereof.
