Abstract
Systems and methods for creating trick play streams for use in adaptive bitrate streaming in accordance with embodiments of the invention are disclosed. One embodiment includes a set of encoding servers that encode source content as a set of streams that are each stored in a separate container file, where the set of streams includes: alternative video streams; an audio stream; and at least one trick play stream. In addition, the trick play stream is encoded at a lower frame rate than the frame rates of the alternative video streams, and each frame of the trick play stream is a picture encoded without reference to another picture in the trick play stream. In addition, the trick play stream is stored in a container file including a trick play index having entries that include a timecode and a location of a frame in the track play stream.
