다중 인터페이스를 탑재한 이동 단말 및 멀티미디어 스트리밍 수신 방법, 다중 망을 이용한 멀티미디어 스트리밍 제공 서버 및 그 방법을 개시한다. 다중 망을 이용한 멀티미디어 스트리밍 제공 방법은 이동 단말의 컨텐츠 요청에 따라 상기 이동 단말의 접속망을 판단하는 단계; 및, 상기 접속망이 적어도 두 개 존재할 경우 컨텐츠의 데이터 패킷을 각각의 접속망에 할당하여 상기 이동 단말로 전송하는 단계를 포함할 수 있다.
Abstract:
Disclosed are a method and an apparatus for measuring energy of network equipment. The method for measuring energy of network equipment includes a step of measuring first power consumption (PU_base) of network equipment consumed in an initial state where the power is turned on; a step of measuring second power consumption (PU_consume) of the network equipment consumed in a traffic condition of a set state when any one of the states among traffic conditions divided into at least two states with respect to the network equipment is set; and a step of measuring actual power consumption (PU) of the network equipment by using the first power consumption (PU_base) and the second power consumption (PU_consume). [Reference numerals] (AA) Start; (BB) State 1: Turn on all ports and connect network cables to all of the ports; (CC) State 2: Turn on all ports and do not connect network cables to the ports; (DD) State 3: Turn off all ports and do not connect network cables; (EE) Generate traffic load with respect to the EUT; (FF) Traffic load = 0, or traffic load = i (0
Abstract:
A communication method using an energy efficient TDMA MAC protocol for hierarchical cooperative communication is provided. A energy efficiency-based hierarchical cooperative communication method in an ad hoc network environment includes a step of comprising a cluster for hierarchical cooperative communication using TDMA MAC wherein the step of comprising the hierarchical cooperative communication can select hierarchical cooperative communication for a lower layer and a higher layer in consideration of energy consumption of the lower layer formed by clustering nodes and the higher layer structured by clustering the lower layers.
Abstract:
PURPOSE: A system and method for servicing content are provided to view content from an interval which is previously viewed. CONSTITUTION: A content meta data is individualized as information about content which a user used from a service server. A set-top box(110) stores individualized content meta data to a storing medium(130) by receiving the data. The set-top box uses user identification information stored in the storing medium if the storing medium is combined. The set-top box connects to the service server storing the content. The set-top box receives content corresponding to the content meta data which is individualized from the service server.
