BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a standby power interrupter using a coaxial cable network, and more particularly to a standby power interrupter using a coaxial cable network, And more particularly, to a standby power cutoff device using a coaxial cable network for shutting off power.

Standby power refers to the power consumed before the electrical equipment is in normal operation (ready state) and refers to the power consumed when the electrical plug is plugged in, even if it is not in use.

When you are not using various electronic products, you can prevent the standby power consumption by turning off the multi-tab switch when you unplug or use a multitap.

In the case of a product operated by a remote control such as a TV or a video, for example, the remote control receiving state ready for turning on is equivalent to the power consumption when the remote control is turned off although the products are currently turned off. It is estimated that the electricity consumed in real life is about 10% of the electricity rate.

Standby power consumption is also increasing with the increase in the number of electronic products equipped with a display device that operates with a remote control and indicates the operation status. In a copying machine or a video recorder, 80% of the total used power is estimated as standby power. Computer o Monitor o Printer o Facsimile o Washing machine o Air conditioner o Television o DVD player o Microwave o o Mobile phone charger consumes lots of standby power.

The International Energy Agency estimates that 60 per cent (W) of household electricity consumption per household will be standby power for OECD member countries. The United States is as small as 5%, but the sum is about $ 1.3 billion per year. In order to solve such a serious standby power problem, the International Energy Agency recommended to countries all over the world to reduce the standby power of all electronic products to less than 1 watt by 2010.

In the case of a central broadcasting control system (an in-house broadcasting system, an intramural broadcasting system in-house broadcasting system or the like) in which management is required at the center (a broadcasting unit), a broadcasting unit for transmitting video and sound and at least one receiver connected through a coaxial cable, The TV receiver is controlled to be connected to an outlet in order to output the broadcast signal from the TV receiver. In such a case, standby power consumption is a problem.

Therefore, there is a need to reduce standby power consumption in a standby state for broadcasting.
