    摘要: The present invention relates to a home gateway device. The home gateway device comprises a main processor to generate information process signals and control signals, a computer bus signal Ethernet adapter unit connected to the main processor to translate the signals between computer bus signals and Ethernet signals, an Ethernet frame process unit connected to the computer bus signal Ethernet adapter unit to forward the received Ethernet frame based on a prearranged policy, an inner interface unit connected to the Ethernet frame process unit to connect interior networking devices, and an outer communication module connected to the main processor and the Ethernet frame process unit. The centralized control of the home gateway device of the present invention can decrease the requirement that the household appliances should be intellectualized, thereby achieving more flexible control and reducing the cost. The uplink and downlink Ethernet signals are controlled by using the prearranged policy to separate the Ethernet signals for Internet access from the Ethernet signals of the household information appliances, and avoid the threat due to the unsafe factors.
