  • Patent number: 7606228
    Abstract: There are provided a home gateway system providing an optical communication packet data interface function and a home broadcast service providing method using the same. The home gateway system is constructed to include a network processor having two Ethernet interfaces connected to a system control processor of a home gateway and an Ethernet switch having an Ethernet multicast traffic processing/IGMP snooping function based on an Ethernet L2 multicast MAC table to thereby simultaneously provide a broadcast service such as a CATV broadcast service, and an Internet data service to a plurality of hosts in a home. In case of a broadcast service, the home gateway system converts a broadcast stream into an IP multicast packet and then processes the broadcast IP multicast packet by an L2 multicast function of an Ethernet switch, thereby making it possible to directly transmit the broadcast IP multicast packet to a host without the help of the control processor.

  • Publication number: 20090203267
    Abstract: A connector for an automobile with high current capability includes a circular terminal and a connector housing. The circular terminal is configured with a cylinder and has a slot formed in an outer periphery of the cylinder at one end and at least one projection formed on the outer periphery at the other end. The connector housing has a cylindrical space for receiving the circular terminal. The cylindrical space has an anti-separation protrusion formed on an inner periphery thereof and coupled with the slot of the circular terminal to prevent separation of the circular terminal. Also, the cylindrical space has at least one anti-rotation groove formed in the inner periphery thereof and engaged with the at least one projection of the circular terminal so as to prevent rotation of the circular terminal. This connector may keep the coupling between the circular terminal and the connector housing in a stable state.

  • Patent number: 7574505
    Abstract: A home server for service convergence and energy-saving, and a method for controlling the same are disclosed to provide broadcast services, Internet services, game platform services, and a broadband network distribution function required by each home network. The home server includes a broadcast processor, a service, a network distribution, a power-supply unit for providing a power-supply signal to each module of the home server, and a power-supply controller. The power-supply controller controls on/off operations of the power-supply signal transmitted from the power-supply unit to each module of the home server according to services and operation states of the service processor and the network distribution unit.
