Abstract
Before receiving an instruction from a media player to encode a media program, a placeshifting device or other video encoder pre-encodes at least a portion of the media program to a low-bandwidth format that can be readily transmitted to the media player upon request. When the media player does instruct the placeshifting device to encode the media program, the placeshifting device initially provides the pre-encoded portion of the media program to thereby allow the media player to begin immediate playback of the pre-encoded portion. After providing the preencoded portion of the media program, the placeshifting device live encodes the remaining portions of the media program according to then-current network conditions to thereby provide the placeshifted video stream to the media player.
