Abstract: The present invention discloses a method of re-transmission of a lost MMT packet by a packet transmission apparatus. The method includes generating a media processing unit (MPU) based on a media fragment unit (MFU) and generating an MMT asset by encapsulating the MPU; generating an MMT packet based on the MPU included in the generated MMT asset; and transmitting the generated MMT packet, wherein the method further comprises adding, in a signaling message related to re-transmission of the MMT packet, delay_constrained_ARQ_flag to indicate whether or not the MMT packet transmission apparatus supports a delay-constrained automatic repeat request (ARQ) function.

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.
