Abstract: A method includes providing a variant playlist file that identifies a plurality of variant streams each corresponding to a different encoding of a same media presentation; tracking a first set of media segments encoded at a first bitrate that correspond to a first playlist file for a first variant stream associated with the variant playlist file; responsive to a second encoded bitrate associated with a second set of media segments that correspond to a second variant stream being higher than the first encoded bitrate: determining a number of media segments to include in a plurality of media segments from the second set of media segments that correspond to the first set of media segments; and providing, to the client device, a second playlist file that identifies a plurality of media segments from the second set of media segments that correspond to respective ones of the first set of media segments.
