Abstract: Disclosed is a method of adjusting a starting point of a peer, the method including receiving a starting point value and a downloading point value of a counterpart peer from the counterpart peer, determining an initial starting point value of a peer based on the received starting point value and the received downloading point value, calculating a ratio between an average play point move rate (APMR) of the peer and an average fragment reception rate of the peer when the determined initial starting point value is less than the received starting point value, calculating a margin based on the calculated ratio, and determining the starting point value of the peer using one of the received starting point value and the received downloading point value, and the calculated margin.

Abstract: A peer may receive a peer list from a hybrid overlay management server in response to an overlay network participation request of the peer, may select a first peer from the received peer list, may establish a connection with the selected first peer, and may establish a connection with at least one of second peers. Propagation of the overlay network participation request may be initiated by the selected first peer, and each of the second peers may correspond to a peer that receives the propagated overlay network participation request. One of the established connections may be determined as a primary path, and a communication may be performed through the primary path.

Abstract: A method of collecting peer-to-peer (P2P)-based content sending/reception information is disclosed herein. In the method of collecting P2P-based content sending/reception information, a first peer accesses a second peer, and exchanges buffer maps with the second peer. The first peer requests the second peer to send a piece of content not owned by the first peer. When the reception of the piece of the content is completed, the first peer generates a receipt message and then signs the receipt message. The first peer sends the signed receipt message to the second peer. The second peer signs the signed receipt message again. The second peer sends the dually signed receipt message to a server.

Abstract: In a multi-source hybrid overlay network including a plurality of peers, an apparatus that recovers missing data occurring in a tree recovery process, acquires data that a peer does not have in a pull method through exchanging buffer maps with a first counterpart peer connected to a primary path recovered in the tree recovery process and at least one second counterpart peer connected to at least one candidate path, and provides data that the first counterpart peer does not have to the first counterpart peer in the push method, when a data recovery policy is a pull method, is provided.

Abstract: An operating method of an overlay management server (OMS) is disclosed. The operating method may include performing a registration process along with a network entity, performing a resource reservation process along with the network entity in response to the registration process being performed, receiving a peer list provision request from the network entity in response to the resource reservation process being performed, and transmitting, to the network entity, a peer list including information associated with an overlay resource for the network entity based on a priority level of the network entity in response to the peer list provision request being received.

Abstract: 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.
