Abstract:
본발명은센서노드중계기에서의센서데이터수집기와하나이상의 6LoWPAN(IPv6 over low power wireless personal area networks) 미지원센서노드들사이의 CoAP(Constrained Application Protocol) 기반센서데이터전송지원방법으로, 상기센서데이터수집기로부터 CoAP 센서데이터요청메시지를수신하는단계와, 수신된 CoAP 센서데이터요청메시지를분석하여, 해당 6LoWPAN(IPv6 over low power wireless personal area networks) 미지원센서노드에 CoAP 센서데이터요청메시지를전송하는단계와, 상기하나이상의미지원센서노드로부터수신된센서데이터를포함하는 CoAP 센서데이터응답메시지를생성하여, 상기센서데이터수집기에응답하는단계를포함한다.
Abstract:
방송 시스템을 이용하여 전자 장치를 제어하는 기술이 개시된다. 제어 신호는 가청 주파수 대역으로 변조되고, 방송 시스템을 이용하여 전송 장치로부터 수신 장치로 전송된다. 수신 장치는 가청 주파수 대역의 제어 신호를 재생하고, 제어 장치는 제어 신호에 따른 동작을 수행한다.
Abstract:
본 발명은 멀티 앵글 방송 서비스 제공 시스템을 제공한다. 전송 장치는 하나의 이벤트를 다양한 각도에서 촬영한 소스 영상들뿐만 아니라 소스 영상들을 포함하는 멀티 화면 영상을 수신 장치로 전송한다. 수신 장치는 멀티 화면 영상을 수신하고, 사용자의 선택에 따라서 소스 영상을 디코딩할 수 있다.
Abstract:
PURPOSE: A customized service providing system and a method thereof are provided to compare content to identity in a mobile device of a user, thereby reducing costs for building a media ID storage. CONSTITUTION: Each media ID buffer(401~40n) stores a media ID and time stamp information which are generated in a media ID generator. The time stamp information identifies time for generating the media ID. A communication unit(501) reads a media ID of at least one channel stored in the media ID buffer. The communication unit generates an ID list. The communication unit outputs the media ID list to a mobile device.
Abstract:
PURPOSE: A broadcasting system interoperating with an electronic device is provided to interoperate broadcasting system and an electronic device by minimizing change of a broadcasting system. CONSTITUTION: A modulation unit(310) modulates a control signal into a frequency band in an audio frequency. A synthesis signal(320) generates a voice synthesis signal by synthesizing the modulated control signal and a voice signal. A transmission unit(330) transmits the voice synthesis signal to a receiving device. The receiving device plays the voice synthesis signal. The control signal is extracted from the reproduced voice synthesis signal and is used for controlling an electronic device(370).
Abstract:
PURPOSE: A broadcasting terminal and a method for providing broadcasting service by cooperation with other terminals based on overlay multicast environment are provided to supply real time broadcasting service through a broadcasting channel by setting the broadcasting channel through inter-terminal collaboration. CONSTITUTION: A broadcasting terminal(1) comprises a channel generation unit(10) and a channel decision unit(20). The channel generating unit generates a virtual channel according to the contents. The class of the contents is differentiated. The channel decision unit sets the virtual channel for the contents providing through the collaboration with other broadcasting terminal. The channel decision unit provides the contents to the set virtual channel. The channel decision unit sets one virtual channel through the merge of the generated virtual channel.
