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.

Abstract: Provided are a method and apparatus for transmitting and receiving media data, which can provide D-layer timing information, which is transmitted from a media transmission service based on an MMT system and required for timely synchronization playout time of the media and media. The apparatus for transmitting the media data comprises a packetizer for generating a delivery layer packet (D-layer packet), which packetizes encapsulation layer data (E-layer data) to include timing information, wherein the timing information comprises sampling time information and transmission process delay information.
