Intelligent-gateway-based digital home network system

The invention discloses an intelligent-gateway-based digital home network system, which comprises a home gateway and a home network. The home gateway is connected with a plurality of pieces of access equipment or the access equipment adopting different access ways at the same time. The home network is divided into a home control network, a digital data network and a home A/V network, wherein the home control network adopts an X210-bus-protocol-based programmable logic controller (PLC) power line carrier technology as a transmission medium; and the digital data network and the home A/V network adopt radio as the transmission medium, and adopt an ultra wideband (UWB) way. The system realizes the comprehensive application of multi-service multi-port technologies, triple play internal network protocol conversion technologies, intelligent routing technologies and network data packet filtering technologies of the home gateway, and brings convenience to the management and communication of home equipment.
