1. An apparatus for generating MPEG Media Transport (MMT) packet structure by packetizing media data, the apparatus comprising:
- an encapsulation unit configured to generate media processing unit (MPU) by encapsulating media fragment unit (MFU) and generate asset based on a media processing unit; and
a packetization unit configured to generate the MMT packet structure by packetizing the media processing unit included in the asset, wherein the MMT packet structure operates over a transport layer; and
the operations for the MMT packet further comprising;
an MPU Encapsulation, for performing packetization, fragmentation, and synchronization functions of transmitted media;
a Delivery of MMT package, for performing flow control, media multiplexing, error control, the scheduling for an delivery session, signaling for synchronization in a delivery environment, and signaling for adaptive delivery; and
a message Signaling, for performing signaling functions, including defining formats of message that manage a transfer and consumption of an MMT package,a presentation, control and management of the transmitted media, and synchronization of the transmitted media;
wherein the packetization unit generates the packet including a packet sequence number field counting the packet transmitted,wherein the asset comprises at least one MPU sharing the same MMT asset ID, andwherein the MPU is identified by the MMT asset ID and a MPU sequence number.

Abstract
The present invention provides a MMT transport packet structure and a method and an apparatus configuring the structure. A method of configuring an MPEG Media Transport (MMT) transport packet for transmitting an MMT payload format, the method comprising: configuring the MMT transport packet so that the MMT transport packet includes at least one MMT payload format unit and a sequence number field for a packet stream, wherein the sequence number field maintains consistency with a sequence number field included in the MMT payload format.
