Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of media content are provided. The media content may include a sequence of one or more periods. The metadata may include a start time attribute and/or a duration attribute of each of the periods. The metadata may determine a start time of each of the periods, and a start time of each of segments included in each of the periods. A terminal may access segments included in each of the periods, may decode and render data of media content included in the segments, and may play back the media content.

Abstract: Provided is a method for transmitting packet-based media data having a header in which an overhead is minimized. A method for media data transmission may comprise the steps of: encapsulating media data to allow a media fragment unit (MFU) header and an M-unit header to share one format; allowing an MMT payload format to include a header field for an operation which is not supported by an RTP header, and transferring the encapsulated media data from a specific entity to another entity; and controlling the transfer of the media data. Therefore, a transmission overhead is minimized, so that it is possible to efficiently transmit media data.

Abstract: A method and apparatus for an adaptive Hypertext Transfer Protocol (HTTP) streaming service using metadata of content are provided. The metadata may include one or more BaseURL elements. Uniform Resource Locators (URLs) of segments forming media may be generated based on the BaseURL elements. Additionally, a URL of a segment may be generated by mapping a BaseURL element among the BaseURL elements to a sourceURL attribute of the segment. Segments indicated by generated URLs may be identical to each other.
