PROBLEM TO BE SOLVED: To provide a TV receiving system where a wasteful power consumption of a booster is suppressed by interlocking a booster power source with a power source of a TV receiver. SOLUTION: A receptacle device 2 of a TV receiving system incorporates a detecting unit 7 which detects power source state of a TV receiver 3 and a transmission unit 6 which transmits a voltage signal of DC10 V to a booster 1. The booster 1 incorporates a power source switch part 15 and a power source control unit 14 which receives the voltage signal and controls the power source part switch 15. The detecting unit 7 detects power source state of the TV receiver 3 and transmits an off detection signal to the transmission unit 6 when the power source is off. When the transmission unit 6 receives the off detection signal, it transmits the voltage signal to the booster 1, while it stops the off detection signal when the power source is on, resulting in the transmission unit to stop outputting of the voltage signal. The booster 1 stops power source of it when receives the voltage signal 10 V.
