The network configuration technology for controlling an electric power sensor node is disclosed. The method for controlling electric power includes transmitting an an Ethernet packet type command message to at least one electric power sensor node through an LRWPAN-Ethernet bridge in accordance with profile information related to an electric power control, the profile information being set by a user; receiving LR-WPAN packet type response messages transmitted from the at least one electric power sensor node in response to the Ethernet package type command message as Ethernet packet type response messages through the LRWPAN-Ethernet bridge; and providing a control result of an electric power equipment corresponding to the at least one electric power sensor node to the user based on the Ethernet packet type response messages.

Method for controlling electric power of electric power controller, LRWPAN-ethernet bridge and sensor node

An energy-aware home gateway based on a network protocol includes a network matching module for performing a physical network interface function on a home and an external network; a processor module for performing an operation and a control function of a system in a active state in which service traffic exists; a memory module used as a system memory of the processor module; and a service function module controlled by the processor module and performing a service function depending on a use state. The home gateway further includes a network protocol agent module for processing control traffic in an idle state in which no service traffic exists; and a power supply module for supplying power to the overall system in the normal active state and for supplying power to the network matching module, the memory module, and the network protocol agent module in the idle state.

Apparatus and control method for energy-aware home gateway based on network

A SMMD media producing apparatus includes: a pre-processor for extracting first media data and produces MXF media data with adjusted resolution using media data of an MXF format; and a neo-data producer for extracting second media data from the MXF media data with the adjusted resolution and produces neo-data to be added to the extracted second media data. The apparatus further includes a media publisher for producing SMMD media data using the neo-data produced by the neo-data producer and the first media data.
