APPARATUS FOR TRANSMITTING DIRECT CURRENT VOLTAGE AND WIRELESS SIGNAL

摘要

PURPOSE: An apparatus for transmitting a direct current voltage and a wireless signal is provided to suit for transmitting a direct current voltage and a wireless signal through one transmission line in a wireless device for a current voltage. CONSTITUTION: An antenna(ANT) and a direct current voltage source(12) being separated to a television receiver(10) are provided. The television receiver(10) has a tuner(14) for detecting a wireless signal of a band wanted by a user out of wireless signals and a voltage relay unit(16) for transmitting a driving voltage to the tuner(14) and a circuit block. A direct current voltage and a wireless signal transmitting device(20) are provided for transmitting a wireless signal received through the antenna(ANT) and a direct current voltage from the direct current voltage source(12) to the tuner(14) and the voltage relay unit(16). The direct current voltage and a wireless signal transmitting device(20) has a signal synthesizer(22) included in a vehicle and connected to the antenna(ANT) and the direct current voltage source(12) and a signal distribution device(24) being mounted in the television receiver(10) and being connected to the tuner(14) and the voltage relay unit(16). The signal synthesizer(22) synthesizes a wireless signal from the antenna(ANT) in a direct current voltage from the direct current voltage source(12), and transmits the synthesized signal toward the signal distribution device(24). The signal distribution device(24) inputs the synthesized signal from a transmission line(21) and separates a wireless signal and a direct current voltage from the synthesized signal.
