Abstract:
1. A video playback system adapted to perform a method of video playback upon a channel start or file seek, the method comprising: receiving an instruction to perform a channel start or file seek for a bit stream of encoded video data, the channel start or file seek indicating a seek location; retrieving one or more tuning parameters selected to set a preference between potential for latency before beginning to display video and potential for defects in the displayed video, wherein different values of the one or more tuning parameters provide different ways to tradeoff the potential for latency versus the potential for defects in the displayed video; based at least in part on the one or more tuning parameters and the seek location, determining a start location at which to start display of pictures from the encoded video data of the bit stream; and decoding at least part of the encoded video data from the bit stream to support display of the pictures beginning from the start location.
