Abstract: 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.
