  • Control apparatus for selectively inhibiting looking/listening in CATV terminal equipment
    Patent number: 5053884
    Abstract: A control apparatus for selectively inhibiting looking/listening in CATV terminal equipment is provided in which an identity number may be inputted for allowing looking/listening even when a changeover switch is set in a looking/listening inhibited state. A comparator compares the inputted identity number with a predetermined number. An inhibition releasing means releases the looking/listening inhibited state set by the changeover switch when the comparator means decides that the two numbers are in accord with one another.
