摘要： The present invention provides a method and a device for transferring transmission characteristic information of multimedia data. According to the present invention, characteristic information on media data which can be partitioned into media processing units (MPUs) is generated in a predetermined number of MPUs, and the generated characteristic information and a flag indicative of the existence of the generated characteristic information are inserted into the media data such that the characteristic information is transferred. Thus, since the characteristic information for transmission can be used according to each media data unit of a small time unit, more effective QoS control is possible in a situation when a transmission environment dynamically changes, such as a mobile network.
