Abstract: A method for providing timing information for synchronizing between packet streams each transported from a first server and a second server under environment of a hybrid delivery service is provided. When the first server transports a first media entity and the second server transports a second media entity, timing information for synchronizing a second packet including a second media entity with a first packet including a first media entity in the second server is generated in response to a transport request for the second media entity from a client and the timing information and the second packet including the second media entity is provided to the client from the second server.

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.
