Abstract
Methods and devices for controlling trick-play video streaming. Upon receipt of a request to play video at a fast-play (e.g., fast-forward or fast-reverse) speed that is some multiple of a normal playback speed, one of multiple possible frame-rate versions of a trick-play track may be selected based on the requested fast-play speed and an available network bandwidth, and a server may stream the selected frame-rate version of the trick-play track to a client for playout. The various frame-rate versions may differ from each other in terms of a rate at which they skip I-frames of the video.
