Abstract: 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.
