Abstract
A method for trick play (fast forward, rewind, etc.) in video streams using adaptive bitrate HTTP delivery protocols includes playing only portions of a video at a current bitrate to achieve the initial trick play functionality. A new trick play bitrate is selected based on a trick play playout rate, the trick play bitrate for the duration of the trick play is retrieved, and operation is switched back to a previous bitrate when normal playback resumes. A system is also specified for implementing a client and server infrastructure in accordance with the method.
