Abstract

PURPOSE: To make it possible to set arbitrarily the time for two channels in time division by controlling a timer set time by an audience.
CONSTITUTION: The first broadcasting station number A and the second broadcasting station number B are stored in memory units 11 and 12 respectively, and each broadcasting station number is inputted to multiplexer 13, and the output is switched alternately by the output of timers 14 and 15. The output of multiplexer 13 is divided in decoder 16, and variable resistor-type station number voltage memory unit 17 is switched to give a desired channel selection voltage to tuner 18, thereby selecting a channel according to the time set by an audience.
