Abstract: Disclosed are an apparatus and a method for providing an adaptive HTTP streaming service using metadata for contents. The metadata includes minimum buffering time property indicating the minimum amount of media contents which are initially buffered. A terminal receives contents from a server before playing the contents and buffers the contents by at least the minimum amount. The metadata includes range properties indicating a target range to which a URL points. A terminal receives bytes from the URL which the range properties indicate, and plays the contents using the received bytes.
