Abstract
Techniques for adaptive backfilling of media fragments are described. As one example, a computer-implemented method includes sending, by a media player, a request for a plurality of media fragments from a content data store, receiving the plurality of media fragments from the content data store with at least one media fragment at a first quality level into a front buffer of the media player via a network, starting playback of the plurality of media fragments from the front buffer after a startup threshold number of media fragments are received in the front buffer, detecting when a backfill threshold of the media player is exceeded by a backfill indicator, and replacing at least one of the plurality of media fragments at the first quality level in the front buffer of the media player with a second, higher quality level variant via the network when the backfill threshold is exceeded.
