Abstract

The invention provides a power line transmission method and device as well as a household network system. The power line transmission device comprises an isolation unit and a power line network interface, wherein the isolation unit is connected in series between an external power line and an internal power line, can isolate a high-frequency noise signal transmitted in the external power line and can transmit a first power signal transmitted in the external power line to the internal power line from the external power line; and the power line network interface comprises at least one digital signal input/output interface for the input or the output of a digital signal, and the power line network interface can convert the digital signal, load the converted digital signal onto the first power signal so as to form a second power signal and transmit the second power signal to the internal power line. The invention provides a noise-free power line for transmitting high-quality image and voice signals, and can provide a noise-free household network system for promoting the upgrade of the industry.

Description

technical field [0001] The invention relates to a method for transmitting video and audio signals through a power line in the field of communication, in particular to a power line transmission method and a device thereof which are not disturbed by mains noise, and a home network system. Background technique [0002] In recent years, with the development of display technology and sound playback technology, people pay more and more attention to the life enjoyment of high picture quality and high sound quality. In view of this, various high-quality and high-quality display signal interface specifications and audio compression signal specifications are available. For example: DVI (Digital Visual Interface, Data Video Interface), HDMI (High Definition Multimedia Interface, High Definition Multimedia Interface), AC-3 (including DolbyDigital, Dolby TrueHD), have also been formulated. These image and sound signal interface specifications enable people to enjoy delicate and realisti...
