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.

First claim

What is claimed is:

1 . 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.

2 . The method of claim 1 , wherein the MMT payload format comprises a field regarding a sequence number that is supported in an RTP packet.

3 . The method of claim 1 , wherein a Presentation Time Stamp (PTS)-equivalent function is provided through an Encapsulation (E)-layer function.

4 . The method of claim 3 , wherein the E-layer function is provided by an M-unit.

5 . The method of claim 1 , wherein in the MMT payload format, units are aggregated or fragmented for each MMT Transport Unit (MTU).

6 . A method of transmitting 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; and transmitting the configured MMT transport packet, wherein the sequence number field maintains consistency with a sequence number field included in the MMT payload format.

7 . The method of claim 6 , wherein the MMT payload format comprises a field regarding a sequence number that is supported in an RTP packet.

8 . The method of claim 6 , wherein a Presentation Time Stamp (PTS)-equivalent function is provided through an Encapsulation (E)-layer function.

9 . The method of claim 8 , wherein the E-layer function is provided by an M-unit.

10 . The method of claim 6 , wherein in the MMT payload format, units are aggregated or fragmented for each MMT Transport Unit (MTU).

11 . An MPEG Media Transport (MMT) transport packet, comprising:
a header part and at least one Media Fragment Unit (MFU), wherein the MFU comprises at least one MMT payload format unit, the header part comprises a sequence number field for a packet stream, and the sequence number field maintains consistency with a sequence number field included in the MMT payload format.

12 . The MMT transport packet of claim 11 , wherein the MMT payload format comprises a field regarding a sequence number that is supported in an RTP packet.

13 . The MMT transport packet of claim 11 , wherein a Presentation Time Stamp (PTS)-equivalent function is provided through an Encapsulation (E)-layer function.

14 . The MMT transport packet of claim 13 , wherein the E-layer function is provided by an M-unit.

15 . The MMT transport packet of claim 11 , wherein in the MMT payload format, units are aggregated or fragmented for each MMT Transport Unit (MTU).
