    Abstract: The present invention relates to a flexible MMT packet transmitting method of multiplex layer media data. The flexible MMT packet transmitting method includes the following steps of: generating an MMT asset by performing a capsulation based on a media processing unit (MPU) which is generated based on a media access unit (AU); generating an MMT composition information (MMT-CI) on the MMT asset; generating an MMT packet by packetizing the MMT asset and the MMT-CI; and transmitting the generated MMT packet to a receiving side. The MMT-CI includes dependency information of at least another MMT asset which is different from the MMT asset. According to the present invention, the reception and transmission of multiplex layer media data are able to notify whether an MMT asset is dependent on another MMT asset and supports a smooth decoding of the MMT asset when providing a hybrid transmission-based MMT service.

    Abstract: PURPOSE: An apparatus for providing streaming contents and a method thereof are provided to efficiently divide media information in active HTTP streaming by using general media information and specific media information. CONSTITUTION: A terminal(110) receives meta data of a media or the meta data about a specific cycle of the media from a server(100)(610). The terminal processes the meta data about the specific cycle(620). The terminal extracts information provided through the meta data. The terminal requests a server of segments(630). The server extracts a data part suitable for the requested segments if there is a need to parse a media(640). The server transmits the segments suitable for each request from the terminal to the terminal(650). The terminal plays the media by decoding and rendering data in the media included within the segments(660).
