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.
