PURPOSE:To send control data for a short period of time without a heavy burden of a terminal controller even when there are lots of terminal equipments. CONSTITUTION:A terminal controller 1 reads repetitively control data to control each terminal equipment 2 from a RAM 4 and uses a generating means 5 to convert the data into an analog video signal and uses an RF modulator 6 to modulate the signal into an RF signal and sends through a control dedicated channel, and the terminal equipment 2 receives the RF signal by a controlling tuner 13 to reproduce control data. Thus, it is not required to send sequentially the control data at every terminal equipment 2 according to a communication procedure. |
