Power line carrier multimedia high-speed broadband interconnection terminal device

Abstract

The invention relates to the field of power line, telephone line and coaxial line carrier communication equipment, and discloses a power line carrier multi-medium high-speed broadband interconnection terminal device. According to the power line carrier multi-medium high-speed broadband interconnection terminal device, network digital signals coming from an Ethernet interface are received and converted into analog signals, and the analog signals are output to a power line carrier interface, a telephone line interface or a coaxial line interface; or the analog signals coming from the power line carrier interface, the telephone line interface or the coaxial line interface are received and converted into the network digital signals, the network digital signals are output to the Ethernet interface and can be loaded on a telephone line, a coaxial line and a power line, and high-speed interconnection communication between double-line media such as the telephone line, the coaxial line and the power line and an Ethernet cable can be achieved. As communication is carried out with unified signal carrier frequencies on the transmission media, the problems of signal conflicts and signal coupling when the power line, the telephone line and the coaxial line are adopted for conducting communication are solved.

Description

technical field [0001] The invention relates to the field of power line, telephone line and coaxial line carrier communication equipment, in particular to a power line carrier multimedia high-speed broadband interconnection terminal device. Background technique [0002] With the rapid development of my country's national economy and the substantial improvement of people's living standards, modern families generally have access to high-definition video networks, telephone line networks, and broadband networks. However, there are contradictions between modern home decoration and the home network application of modern light-speed networks: [0003] 1. The main application of high-definition network video is on the TV, and there is no network cable next to the TV, only the coaxial cable and the power line. [0004] 2. The application of VOIP requires a network, and there may be only telephone lines in places suitable for placing telephones, and there may be no power lines and ne...
