Abstract

A method and an apparatus for transmitting data in a multimedia transmission system are provided. The method includes receiving, from an encapsulation function layer, a second data unit having one or more first data units, configuring payload header information, the payload header information including a payload type and configuration information, by analyzing header information of the second data unit, configuring one or more payloads from the second data unit based on sizes of the one or more first data units, configuring a multimedia data packet by combining payload header information corresponding to each of the one or more payloads, and transmitting the multimedia data packet to a counterpart entity. Each of the one or more payload includes at least one payload element, the type of which is selected from among a first type, a second type, a third type, a fourth type, and a fifth type.

Claims

1-25. -25. (canceled)

26. A method for transmitting media content in a multimedia system, the method comprising:

generating at least one multimedia data packet based on a data unit fragmented into at least one sub data unit, each multimedia data packet including a packet header and a payload; and

transmitting the at least one multimedia data packet,

wherein payload data included in the payload comprises metadata of the data unit or data of a sub data unit,

wherein each of the at least one multimedia data packet comprises type information indicating that the payload data comprises the metadata of the data unit or indicating that the payload data comprises the data of the sub data unit, and

wherein the metadata of the data unit comprises file type information of the data unit.

27. The method of claim 26, wherein the metadata of the data unit comprises information regarding configuration of the sub data unit.

28. The method of claim 26, wherein the metadata of the data unit comprises a MOOV box having codec configuration information and an Motion Picture Experts Group (MPEG) Media Transport (MMT) Processing Unit (MMPU) box being placing after the file type information to provide information regarding to the data unit.

29. The method of claim 26, wherein each of the at least one multimedia data packets comprises information identifying type of the data included in the payload data.

30. The method of claim 26, wherein the payload comprises a field indicating whether timing information is included in the payload data.
