Disclosed are an apparatus and a method for configuring an MMT payload header. The apparatus for configuring an MMT payload header, according to one embodiment, extracts a sequence number of a media processing unit (MPU) comprising one or a plurality of media fragment units, which are to be aggregated into one payload and mapped, and displays the extracted sequence number of the MPU on the MMT payload header. Specifically, the apparatus for configuring an MMT payload header displays the sequence number commonly associated with a plurality of MFUs on the header only once, when the plurality of MFUs in one payload are aggregated in the one payload and mapped.

No: 16/158035 Application Filed: October 11, 2018 Assignees: Electronics and Telecommunications Research Institute (Daejeon, KR), YONSEI UNIVERSITY WONJU INDUSTRY-ACADEMIC COOPERATION FOUNDATION (Wonju-si Gangwon-do, KR) Claim: 1. An apparatus for constructing an MPEG Media Transport (MMT) payload header and transmitting a multimedia packet including the MMT payload header based on an MMT system, the MMT system including an encapsulation layer and a delivery function layer, the apparatus comprising: at least one processor; and a memory storing at least one instructions executed by the at least one processor, the instructions for: receiving at least one data unit output from the encapsulation layer, each data unit including a data unit header; determining whether there are more than one Media Fragment Unit (MFU) to be aggregated and mapped into one payload in the at least one data unit; including once, in the MMT payload header, an Media Processing Unit (MPU sequence number of an MPU to which more than one MFU belong on the delivery function layer; is forming an MMT transport packet by applying the MMT payload header to MMT payload data; and transmitting the formed MMT transport packet, wherein the MFU is a container format that is independent of any specific media codecs and contains coded media data that can be independently processed by a media decoder and the MPU is a container format that contains one or more MFUs. Claim: 2. The apparatus of claim 1, wherein the at least one instructions further includes instructions for extracting, from at least one data unit header of the at least one data unit, an MPU sequence number of a MPU to which one MFU or a plurality of MFUs to be aggregated and mapped into one payload belong. Claim: 3. The apparatus of claim 1, wherein the at least one instructions further includes instructions for including a fragment sequence number of each MFU into each header of data units (DUs). Claim: 4. A method of constructing an MPEG Media Transport (MMT) payload header for transmitting a multimedia packet including the MMT payload header based on an MMT system, the MMT system including an encapsulation layer and a delivery function layer, the method comprising: receiving at least one data unit output from the encapsulation layer, each data unit including a data unit header; determining whether there are more than one Media Fragment Units (MFUs) to be aggregated and mapped into one payload in the at least one data unit; including once, in the MMT payload header, an Media Processing Unit (MPU sequence number of an MPU to which more than one MFU belong on the delivery function layer; forming an MMT transport packet by applying the MMT payload header to MMT payload data; and transmitting the formed MMT transport packet, wherein the MFU is a container format that is independent of any specific media codecs and contains coded media data that can be independently processed by a media decoder and the MPU is a container format that contains one or more MFUs. Claim: 5. The method of claim 4, further comprising extracting, from at least one data unit header of the at least one data unit, an MPU sequence number of a MPU to which one MFU or a plurality of MFUs to be aggregated and mapped into one payload belong. Claim: 6. The method of claim 4, further comprising including a fragment sequence number of each MFU into each header of data units (DUs). Current International Class: 04; 04; 04; 04
