PURPOSE:To supply a DC power supply and a high frequency signal from a booster to a home bus and to supply an AC power source to the booster through one and same coaxial cable by connecting DC and AC cut-off capacitors between the booster and a complete 2-way distributer. CONSTITUTION:The titled equipment is provided with a power transformer 1 stepping down a commercial power AC 100V into a required voltage, a rectifier 2 rectifying the AC, a DC voltage regulator 3 stabilizing the rectified DC, a power superimposition transmission unit 4 to superimpose the DC output voltage from the DC voltage regulator 3 onto a home bus, and the complete 2-way distributer distributing the video signal from the booster and distributing the DC power supply in two-way, and the DC and AC cut-off capacitor 6 is connected between the booster and the distributer. Thus, the AC power is supplied to the coaxial cable connecting to the booster, while the DC power is supplied to the home bus and the video signal from the booster is sent to the home bus altogether.
