Dynamic bit rate encoding

Abstract

Systems and methods for performing bit rate encoding are described. One of the methods includes receiving data indicating a change in a first connection speed that is associated with a first network. The change generates a second connection speed. The method further includes determining whether a media file is being downloaded. The method also includes determining that a current segment of the media file is being downloaded. The current segment is downloaded at a first bit rate and the first bit rate is associated with the first connection speed. The method includes determining whether the media file includes a remaining segment to be downloaded. The current segment precedes the remaining segment. The method includes identifying a second bit rate based on the second connection speed, receiving the remaining segment at the second bit rate, and stitching the remaining segment with the current segment.
