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.

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.
