Abstract

A time-dependent data control system which includes a control unit capable of transmitting data to a plurality of terminals. Each of the terminals is in communication with and receives transmissions of data such as 'changed data' and 'change time' from the control unit. Each of the terminals further include a clock capable of comparing the 'change time' data received from the control unit with the current time and, once the change time transmitted by the control unit occurs, displaying the changed data received from the control unit. Thus, individual terminals change their display contents independently of each other based upon the data received from the control unit and are capable of changing the display contents simultaneously, or at a predetermined number of preset times. In addition, the terminals are placed in a standby rest mode to reduce the energy requirements and power consumption and can be brought into an enabling mode upon transmission of a data start signal transmitted by the control unit.
