Abstract:
PURPOSE: To automatically provide an AC voltage from an AC outlet to a scramble broadcast decoder only when a scramble broadcasting channel is selected.
CONSTITUTION: Only when a scramble broadcasting channel is selected tobe received by a channel selecting remote controller 38, an AC supply switch 40 is closed (a moving contact 40a and a fixed contact 40b are connected) by a micro processor 31, and an AC outlet 4 provides a scramble broadcastdecoder 7 with an AC voltage. Therefore, only when a scramble broadcastingchannel is selected to be received, a scrambled program signal SP1a is descrambled by a scramble broadcast decoder 7, so that a proper program signalSP1c is obtained. Thus, power consumption by a scramble broadcast decoder 7 is saved. (From: Patent Abstracts of Japan, Section: E, Section No. 1367, Vol. 17, No. 253, Pg. 156, May 19, 1993 )
