Abstract

PURPOSE:To receive FM broadcasting in addition to normal TV broadcasting by converting FM broadcasting signals into TV signals of a prescribed channel and mixing the FM signals with normal TV signals to send them simultaneously to TV receivers in a installation. CONSTITUTION:An FM broadcasting signal received by an antenna 1 is frequency-converted into a TV voice signal of a prescribed channel, e.g., Ch7, by a frequency converting part 7 in an FM broadcasting receiver 2. The frequency-converted signal is mixed with a false video signal in a false video signal carrier injecting part 10 and supplied to a mixer 19 as a TV signal of the prescribed channel, Ch7, through a level adjuster 18. The mixer 19 mixes the TV signal of Ch7 with the TV signal received by the antenna 1 and level- adjusted by a preamplifier 17 and the mixed signal is sent to TV receivers 5, 5.... Consequently, the receivers 5 selected and turned to a normal broadcasting channel can receive TV broadcasting and other receivers selected and turned to the Ch7 can receive FM broadcasting.
