Abstract: A system and method for providing media streaming are provided. A media description file having a range string indicator is used to specify location offsets of a plurality of media fragments within a media file. The range string may be stored directly in the media description file or the media description file may contain an indicator specifying a file containing the range string. The media description file may also include a range unit specifying the size of the offsets in the range string. In an embodiment, offsets within the individual media fragments may also be provided, either in the media description file or in a different file.

Abstract: A system and method for media adaptation are provided. A method for providing media to an electronic device includes receiving a request for a media with a set of characteristics, and determining if the media with the set of characteristics resides in a media storage. The method also includes if the media with the set of characteristics resides in the media storage, retrieving the media with the set of characteristics from the media storage. The method further includes if the media with the set of characteristics does not reside in the media storage, transcoding an alternate media with an alternate set of characteristics to produce a transcoded media with the set of characteristics. The method additionally includes providing the media with the set of characteristics from the media storage or the transcoded media with the set of characteristics to the electronic device.
