20080279118 | SYSTEM AND METHOD FOR PROVIDING SESSION INITIATION PROTOCOL BASED CONFERENCE SERVICE - A system for providing a session initiation protocol based conference service includes: a conference host terminal that produces requests to setup a call using identification information, to make a registration of participants to be invited to a conference session using a conference identifier, and to initiate the conference session using the conference identifier; a plurality of conference participant terminals as the participants that participate in the conference session; and a conference server having the identification information. The conference server issues the conference identifier to the conference session; stores therein the participant information; and sends to each of the conference participant terminals corresponding to the stored participant information a message to invite the conference participant terminal to the conference session, the message containing the conference identifier, thereby creating the conference session with conference participant terminals which have sent to the conference server acknowledgement messages. | 11-13-2008 |
20110087775 | PEER-TO-PEER CONTROL DEVICE AND TRANSMISSION OVERLAY MANAGEMENT METHOD - A peer-to-peer (P2P) control device receives peer registration requests from a plurality of peers which want to receive contents and registers information regarding the plurality of peers, and receives an application service and contents registration request from at least one contents server providing contents and registers the information regarding the application service and contents. When the P2P control device receives a request for generating an overlay of desired contents from a requesting peer, it generates a P2P overlay, a logical path along which contents are to be transmitted to the requesting peer, by using the registered information regarding the plurality of peers, information regarding a network to which the plurality of peers are connected, and information regarding the application service corresponding to the desired contents, and delivers the connection information to the requesting peer with reference to the P2P overlay. | 04-14-2011 |
20110137993 | SYSTEM AND METHOD FOR PROVIDING CONFERENCE SERVICE USING NETWORK SERVICE BASED ON USER TERMINAL CAPABILITIES - A system and method for providing a conference service using a network service based on user terminal capabilities are provided. In the method, it is determined to perform media conversion required for media transfer corresponding to the capabilities of the user terminal in response to a conference service join request, and a transcoding service location of a network device supporting the media conversion is searched over the Internet. Then, a connection is made to the transcoding service location to perform the media conversion, and the converted media is delivered to the user terminal. | 06-09-2011 |
20110154392 | METHOD OF PROVIDING SERVICE INFORMATION, SYSTEM THEREOF, AND METHOD OF RECEIVING SERVICE INFORMATION - An information providing system includes: a service provider list provider that receives a service provider list requesting message for a service that a terminal device wants and transmits a service provider list information message including a service provider list including a service provider server providing the service to the terminal device; and a service list provider that receives a service list requesting message requesting a service details list provided by the service provider server included in the service provider list from the terminal device and transmits a service list information message including the service details list provided by the service provider server to the terminal device. | 06-23-2011 |
20120143953 | APPARATUS AND METHOD FOR RECEIVING AND TRASMITTING MULTIMEDIA CONTENTS - Disclosed is a method for receiving a multimedia content between peers on a peer-to-peer network, including: establishing a neighbor connection relationship which is a relationship to interactively transmit and receive the multimedia content, with the other peer on the peer-to-peer network; establishing a donator connection relationship to receive the multimedia content from the other peer, based on a donator approval request message transmitted to the other peer; receiving a multimedia content piece related message from the other peer based on the established donator connection relationship; and receiving a required multimedia content piece from the other peer according to a result of parsing the multimedia content piece related message. | 06-07-2012 |
20120150959 | SPAM COUNTERING METHOD AND APPARATUS - In an apparatus for countering IP multimedia spam, a transmitter receives an IP application, and blocks the IP application when the IP application is determined as spam. A spam identifier receives the IP application from the transmitter, and analyzes at least one of a content of the IP application and a protocol of the IP application. A controller controls the spam identifier based on a setting for anti-spam, and determines whether the IP application is spam or not based on the analyzing result for the IP application of the spam identifier and transmits the determining result to the transmitter. | 06-14-2012 |
20120246332 | CIRCULAR BUFFER AND METHOD FOR MULTIMEDIA STREAMING SERVICE BASED PEER-TO-PEER - The present invention relates to use of a circular buffer used by a peer in a multimedia streaming service based on peer-to-peer (P2P), and an operating method thereof. A circular buffer of the present invention may include a buffering section to process a delayed data fragment transmission request from at least one peer present in a network according to a playback of a multimedia content, a storing section to store data to be provided to the at least one peer, a continuous storing section in which data fragments for the playback of the multimedia content are stored in serial order, and a discontinuous storing section in which a space for a received data fragment to be shared with the at least one peer is reserved and a space for a data fragment to be received is reserved. | 09-27-2012 |
20140019543 | PEER-TO-PEER NETWORK SYSTEM WITH MANAGEABILITY - A peer-to-peer network system provides at least one peer with information for configuration of a peer-to-peer network to optimize the configuration of the peer-to-peer network by using at least one of information about a status of the at least one peer, information about a status of an underlying network and information about a user in respect of services. | 01-16-2014 |
20140115079 | METHOD FOR PROOF OF PLAY (PoP) OF DIGITAL SIGNAGE CONTENT - Provided a proof of play (PoP) method of a digital signage terminal and a digital signage server, the PoP method of the digital signage terminal including obtaining a digital signature and a PoP message generation policy provided by a content owner, generating log data comprising information on a play of at least one piece of content, based on the PoP message generation policy, generating a PoP message using information on the digital signature based on the generated log data, and providing the PoP message to at least one of the digital signage server and the content owner. | 04-24-2014 |
20140313014 | DIGITAL SIGNAGE SYSTEM AND EMERGENCY ALERTING METHOD USING SAME - A digital signage system and a method of providing information using the digital signage system are disclosed. The digital signage terminal includes an emergency detection unit, an emergency detection message generation unit, a communication unit, and an emergency alert message processing unit. The emergency detection unit collects the surrounding emergency-related information of the digital signage terminal. The emergency detection message generation unit generates an emergency detection message including the collected emergency-related information. The communication unit transmits the generated emergency detection message to a digital signage server, and receives an emergency alert message including an emergency alert corresponding to an emergency situation from the digital signage server. The emergency alert message processing unit parses the emergency alert message, and provides the emergency alert included in the emergency alert message to a user. | 10-23-2014 |
