Abstract
Systems and methods for fast startup of video playback in accordance with embodiments of the invention are disclosed. One embodiment includes identifying a location within the first video stream at which to commence playback, identifying a frame of video in the second video stream that corresponds with the identified location in the first video stream, requesting the identified frame of video in the second video stream, requesting and buffering video from the first video stream starting at the identified location, decoding the identified frame of video in the second video stream, displaying the decoded frame of video in the second video stream while buffering video from the first video stream, decoding video from the first video stream, and displaying the decoded video from the first video stream when the first video stream is sufficiently buffered for continuous playback.
