Abstract

The invention provides a broadcast signal conversion device, capable of reducing the consumed electric power of a self-luminescence type monitoring device and a loudspeaker even though without a broadcast receiving device with the consumed electric power reduction function. The broadcast signal conversion device comprises a switching part for switching on / off the signal of the transmission path for transmitting the signal from a signal input part to a signal output part. A connection part is connected with a moving body detection device for detecting the moving body. A moving body detection part receives the moving body detection signal from the moving body detection device. A switch control part controls the switching part when not receiving the moving body detection signal to cut off the signal in the transmission path. A time measurement part measures the passing time after the receiving state of the moving body detection signal is changed. When the passing time measured by the time measurement part exceeds the preset time, the switch control part controls the switching part to switch the on / off of the signal in the transmission path.
