Abstract
A method of delivering media data in a hybrid network capable of providing broadcasting and internet communication together is provided. The method includes generating a Media Processing Unit (MPU) to process media data, and delivering the generated MPU, wherein the MPU includes an MPEG Media Transport (MMT) Processing Unit (MMPU) box including information on the MPU, a Media Data box (MDAT) including one or more media data fragments which are generated from the media data, and an MMFU box including information on each media data fragment.
Claims4
An apparatus for transmitting media data in a broadcast network, the apparatus comprising:
- a transceiver;
- and
- a controller coupled to the transceiver, wherein the controller is configured to:
- identify a media processing unit including a media data part and an information part, the media data part including at least one fragment of the media data and the information part including information on the media processing unit and information on the at least one fragment of the media data, and
- transmit the media processing unit,
- wherein the information part includes first information indicating whether the at least one fragment of the media data in the media processing unit is timed data or non-timed data,
- wherein the information part includes offset information and length information, the offset information indicating a position of the at least one fragment of the media data within the media processing unit, and the length information indicating length of the at least one fragment of the media data, and
- wherein the information part includes third information indicating whether the media processing unit comprises all fragments described by a fragment structure.
