20100010900 | SYSTEM AND METHOD OF INTERACTIVE AREA ADVERTISEMENT USING MULTICAST TRANSMITTING - An interactive advertisement system and a method thereof are provided. The interactive advertisement system includes an advertiser server, a local advertisement server, and a service receiver. The advertiser server requests registration of advertisement information by setting advertisement ID including target service areas and provides services in response to an order of available services corresponding to the advertisement information. The local advertisement server stores and registers the advertisement information including the advertisement ID corresponding to the registration request of the advertiser server, multicasts the registered advertisement information with the advertisement ID through an IP network, and transmits information related to a service request to the advertiser server. The service receiver extracts advertisement information providing a corresponding service from the received advertisement information, outputs the extracted information through a user interface, requesting the local advertisement server to order the input service, and receives the corresponding service from the advertiser server. | 01-14-2010 |
20100218230 | SYSTEM AND METHOD FOR INTERACTIVE IPTV BROADCASTING SERVICE OF USER PARTICIPATION - There is provided a interactive IPTV broadcasting service system of user participation, the system including: a broadcast controller reserving time of IPTV broadcast channels to perform an IPTV broadcast according to the reserved time, notifying user participation to accept the user participation during the broadcasting service, and controlling so that video of the user making a request for participation in broadcasting is included in video of the broadcast in progress, and then broadcast, a plurality of clients each notifying the broadcast controller of the request of the corresponding user when the participation in broadcasting is requested according to a selection of the IPTV broadcasting user and generating video and audio traffic of the corresponding user, and a media server relaying the users' participation in broadcasting between the broadcast controller and the clients, and receiving and mixing video and audio traffic of a broadcaster and the video and audio traffic of each of the users making the requests for the participation in broadcasting. Accordingly, the broadcaster can synthesize videos of users into broadcast contents. | 08-26-2010 |
20110061070 | PARTICIPANT TERMINAL DEVICE, WIRED AND WIRELESS COUPLED SERVER FOR SUPPORTING BROADCASTING PARTICIPATION, AND METHOD OF PROVIDING PARTICIPATIONAL BROADCASTING SERVICE - Provided are a participant terminal device, a wired and wireless coupled server for supporting broadcasting participation, and a method of providing a participational broadcasting service. The wired and wireless coupled server may include: an information obtainment unit to obtain channel information associated with a broadcast provided to at least one participant terminal device among a plurality of terminal devices in response to a participation request from the at least one participant terminal device; and an information processor to enable the at least one participant terminal device to access a participation control server associated with the broadcasting participation using participation address information corresponding to the obtained channel information by identifying the participation address information and transmitting the identified participation address information to the at least one participant terminal device. | 03-10-2011 |
20110082691 | BROADCASTING SYSTEM INTERWORKING WITH ELECTRONIC DEVICES - Provided is a technology of controlling an electronic device using a broadcasting system. A control signal may be modulated to an audible frequency band and thereby be transmitted from a transmission apparatus to a reception apparatus using the broadcasting system. The reception apparatus may reproduce the control signal of the audible frequency band. A controller may perform a control operation based on the control signal. | 04-07-2011 |
20110125917 | OVERLAY MULTICAST SYSTEM FOR GROUP MEDIA TRANSMISSION APPLICATION SERVICE COMPOSED OF MULTIPLE STREAM - Disclosed is an overlay multicast system for a group media transmission application service composed of a multiple stream, wherein, when an additional stream is newly transferred to a predetermined node in an overlay network, the overlay multicast system transmitting a plurality of streams in the overlay network generates a multiple stream by muxing a main stream inputted from a parent node and the additional stream based on stream correlation information in the predetermined node, and transmits the generated multiple stream to a child node. | 05-26-2011 |
20120165040 | METHOD FOR LOCATING WIRELESS NODES USING DIFFERENCE TRIANGULATION - Disclosed is a method for locating wireless nodes using difference triangulation, including: storing information transmitted from three or more fixed wireless nodes while moving on a movement path; calculating displacement vectors among three or more measurement points sharing the information of three or more fixed wireless nodes on the movement path; calculating positional information of the mobile wireless node at another measurement point by reflecting the calculated displacement vectors to the positional information of the mobile wireless node calculated at a measurement point of a region where a location of at least one fixed wireless node is known; and calculating positional information of a location-unknown fixed wireless node by the positional information of the mobile wireless node calculated at the three or more measurement points and information received from the location-unknown fixed wireless node. | 06-28-2012 |
20130011017 | METHOD OF OBTAINING SPATIAL IMAGES ON DEMAND - Provided is a method of obtaining spatial images on demand. The server segments a spatial image into a plurality of regions to detect an isolated region whose continuity with peripheral regions is less than a threshold value, generates geographic information corresponding to the detected isolated region, and generates a capture request message including the generated geographic information. In addition, the capture request message may be transmitted to at least one terminal using unicast scheme, a multicast scheme, an anycast scheme, or a broadcast scheme. The capture request message may comprise a capture condition value such as a capture direction, a capture angle, a capture time, a zoom information and an exposure value. At least one terminal which meets the capture condition value within the capture request message transmits a captured image to the server. | 01-10-2013 |
20130091250 | INTERMEDIATE NODE APPARATUS FOR CONFIGURING SENSOR NETWORK AND SENSOR DATA PROCESSING METHOD USING INTERMEDIATE NODE APPARATUS - Disclosed is an intermediate node apparatus for configuring a sensor network and a sensor data processing method using the intermediate node apparatus. The intermediate node apparatus may deliver sensor data measured by a sensor node apparatus to a neighboring node apparatus and may store the sensor data in a database. | 04-11-2013 |
20140059629 | TWO-WAY BROADCAST SERVICE PROVIDING SYSTEM AND METHOD INCLUDING MEDIA TRANSMISSION APPARATUS - Two-way broadcast service providing system and method including a media transmission apparatus are provided. The media transmission apparatus includes a data communication interface that receives participant media from at least one participant terminal via a communication network, a media conversion unit that converts the participant media received through the data communication interface in accordance with a broadcast media standard, and a broadcast interface that transmits the participant media converted through the media conversion unit to a broadcast apparatus so that the participant media is included in broadcast contents. | 02-27-2014 |
20140171137 | COMMUNICATION DEVICE AND CONTROL DEVICE FOR CONTROLLING COMMUNICATION LINKAGE BETWEEN COMMUNICATION DEVICES - A control device is provided which controls wireless communication linkage between communication devices.
