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.
Claims20
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, and
- wherein the MPU is identified by the MMT asset ID and a MPU sequence number.
