Abstract

A communication system utilizing a power line communication to be carried out in a building including a plurality of houses, in which a video and audio signal in a high frequency band such as TV or CATV signals are received in common, is provided in a manner such that the power line and the communication line are combined with each other to form a signal transmission path, by which reduces the attenuation of a communication signal, so as to ensure an excellent communication state without increasing the manufacturing cost of the system.
