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.

Claims4

Dependent claims

An apparatus for receiving media data in a multimedia system, the apparatus comprising:

a receiver configured to receive a transmission packet including information for delivery characteristics of the media data that includes at least one data unit, the transmission packet being generated based on the data unit;
and
a controller configured to control the receiver,
wherein the information for the delivery characteristics comprises bitstream information and quality of service (QoS) information for delivery of the media data,
wherein the QoS information comprises a first field indicating characteristics about packet loss of the media data and a second field classifying a service class of the media data,
wherein the bitstream information includes a first field indicating a minimum bit rate for delivery of the media data and a second field indicating a maximum buffer size for delivery of the media data.
