Abstract: Disclosed are systems and methods to deliver media files at a highest perceived presented quality. Rather than measure quality as a difference between an encoded version of the media file and the original version of the media file, in accordance with the disclosed implementations, quality is based on a presented quality of each fragment of a media file when presented by a device to a user. The disclosed implementations determine a presented quality score for each fragment of a media file, the presented quality score indicative of a predicted quality of the fragment as perceived by a user when the fragment is presented. The presented quality score may be determined based on one or more of a bitrate used to encode the media segment, a device type of a device used to present the media segment, the content of the segment itself, etc.
