Abstract: There are provided a method and apparatus for delivering transport characteristics of multimedia data. According to an aspect of the present invention, transport characteristics of media data that can be divided in a unit of a Media Processing Unit (MPU) are created in a unit of a predetermined number of MPUs, the created transport characteristics and a flag indicating presence or absence of the created transport characteristics are inserted into the media data, and the resultant media data is delivered. Accordingly, by using transport characteristics in units of media data unit groups, each media data unit corresponding to a short time length, it is possible to effectively control Quality of Service (QoS) in a dynamically changing transport environment, like a mobile network.
