Abstract: Disclosed is a display device connection method for rapidly delivering data to a plurality of display devices. A peer-to-peer (P2P) overlay network including the plurality of display devices as member peers is configured to distribute content. In this case, an overlay management server (OMS) connects first member peers through a network as a tree topology using a source peer providing the content as a root node, and transmits fragments of the content to a child peer based on a number of peers to which each of the member peers is capable of transmitting the fragments of the content for a preset period of time, and the source peer directly transmits the fragments of the content to a second member peer that is not included in the tree topology among the member peers based on a predetermined limit on a hop count.

Abstract: Provided are method and apparatus for transmitting session-related parameters required for controlling session maintenance to a multicast agent in a relayed multicast network. The session manager in the relayed multicast network generates control data containing at least one of a T_PPROBE field, an N_PPROBE field, a T_HB field, a N_HB field, a T_HSOLICIT field, an N_HSOLICIT field, a T_HANNOUNCE field, a N_HANNOUNCE field, a T_RELAY field, an N_RELAY field, and a T_LEAVE field, and transmits the generated control data to the multicast agent. Accordingly, relayed multicast service can be provided for each session by setting session-related parameters for each session in a relayed multicast network and transmitting them to a multicast agent.
