摘要： A method for transmitting and receiving an MMT protocol (MMTP) packet by an MPEG media transport (MMT) receiver is disclosed. The method comprises the steps of: by an MMT receiver, establishing a network connection with an MMT transmitter such that an MMTP packet can be transmitted and received; generating a first MMT signaling message; converting the generated first MMT signaling message into a first MMTP packet; transmitting the first MMTP packet by means of the established network connection; receiving a second MMTP packet by means of the established network connection; generating a second MMT signaling message by means of the second MMTP packet; receiving a third MMTP packet; and reconstructing MPU data by means of the third MMTP packet and the second MMT signaling message. The step for receiving the third MMTP packet comprises the steps of: establishing a changed network connection on the basis of the second MMT signaling message; and receiving the third MMTP packet by means of the changed network connection.

摘要： A method and an apparatus for controlling media delivery in a multimedia transport network. The method includes transmitting composition information (CI) on media assets within a media package to be transmitted, to a user equipment (UE), packetizing the media assets of the media package to packets, transmitting some of the packets to the UE, receiving a feedback message including information on an available bitrate determined by the UE from the UE while the some of the packets are transmitted, selecting media data, which can be transmitted according to the available bitrate, from the media package by using asset delivery characteristics (ADCs) of the media assets within the media package, and packetizing the selected media data to packets and transmitting the packets to the UE.
