Abstract
A method for adaptive streaming of a media content, wherein the method comprises receiving a media presentation description that provides presentation information for the media content, determining a plurality of representations from the media presentation description that comprise segments that are provided with bitrate and quality information, selecting a media segment that meets a desired quality level to download from one of the representations, updating a buffered media time for downloading the media segment, and determining when to switch to another representation by comparing the buffered media time to a switching threshold value.
