Abstract
Systems and methods for performing smooth visual search of media encoded for adaptive bitrate streaming using trick play streams are disclosed. One embodiment of the invention includes requesting and buffering portions of video from at least one of the alternative streams using a playback device, decoding the buffered portions of video using a decoder on the playback device, receiving at least one user instruction directing the playback device to perform a visual search of the media, requesting and buffering potions of video from the trick play stream using the playback device, and decoding the buffered portions of the trick play stream using a decoder on the playback device.
