Abstract
An apparatus and a method for transmitting multimedia data in a broadcast system are provided. A method for constructing a payload for a multimedia frame to be transmitted via a heterogeneous network, in a broadcast system that supports an Internet protocol-based multimedia service, includes dividing the data so as to transmit data of at least one media type and constructing a data region based on each datum of the divided data, constructing a header region including information on the state of the data contained in the data region and/or information on the data region, and combining the data region and the header region to construct a payload for the multimedia frame.
Claims2
A method for receiving media data in a broadcasting system, the method comprising:
- receiving a packet including a packet header and a packet payload of media data,
- wherein the packet payload comprises:
- a data unit generated from the media data,
- a fragmentation indicator indicating information about fragmentation of the data unit in the packet payload,
- length information on the packet payload,
- aggregation information on whether more than one data unit is comprised, and
- sequence number information on the data unit,
- wherein, if the data unit is fragmented, the packet payload comprises a fragmented data unit and the fragmentation indicator indicates information which part of the data unit is included in the packet payload, and
- wherein, if the data unit is not fragmented, the packet payload comprises at least one complete data unit and the fragmentation indicator indicates that the packet payload includes the at least one complete data unit.
