METHOD FOR TRANSMITTING MEDIA DATA VIA A HETEROGENEOUS IP NETWORK INDEPENDENTLY OF A MEDIA CODEC

摘要

The present invention relates to a method for transmitting media data via a heterogeneous IP network, the method efficiently transmitting, independently of a specific media codec, media streaming in the format of a coded media fragment data unit, including a header of a media unit having a minimized size and a simplified structure.

1. A method of transporting coded media data in a system for transporting coded media fragment data via a heterogeneous IP network, the method comprising:
receiving a media unit (MU) having a format independent on a particular media codec from a media codec layer; generating an MMT asset by encapsulating the generated media unit; generating an MMT package by encapsulating the generated MMT asset; generating an MMT payload format upon receiving the generated MMT package; and generating an MMT transport packet upon receiving the generated MMT payload format, wherein the media unit includes a header part and a data part, the data part includes coded media fragment data, and the header part includes an indicator indicating whether or not the coded media fragment data includes a random access point, an indicator indicating whether or not the coded media fragment data includes a start portion of coded media data, and an indicator indicating whether or not the coded media fragment data includes a final portion of the coded media data.
