METHOD FOR TRANSPORTING MEDIA DATA HAVING ACCESS UNITS THAT ARE DIVIDED INTO MULTIPLE MEDIA FRAGMENT UNITS THROUGH HETEROGENEOUS IP NETWORKS, WHICH IS CAPABLE OF USING MEDIA TIME INSTANCES WITHOUT USING EXPLICIT ACCESS UNITS BY USING A TIME INSTANCE UNIT SHARING AN IDENTICAL MEDIA TIME INSTANCE

摘要

PURPOSE: A method for transporting media data having access units that are divided into multiple media fragment units (MFU) through heterogeneous IP networks is provided to achieving a media data packaging corresponding to various media data structures by generating media processing units (MPU) using fragmented data constituting an access unit as a constituent unit.;CONSTITUTION: A media data transmission device receives media data (S100). A stream divider of the media data transmission device divides the media data into a media fragment units having a network abstraction layer (NAL) (S200). A header generator of the media data transmission device generates a header of a media unit (M-Unit) (S200). A packaging unit of the media data transmission device generates the M-unit from the media fragments units (S300).;COPYRIGHT KIPO 2013;[Reference numerals] (AA) Start; (BB) End; (S100) Receive media data; (S200) Divide the media data; (S300) Generate an M-unit
