摘要:
A system for a mobile wireless device to receive and display a video stream while preventing overflow or starvation of its receive buffer by requesting changes to the video streaming or encoding rates and by controlling the video playback frame rate. The current receive buffer level is used to make comparisons with several thresholds, the results of which are used to trigger actions. If the current receive buffer level has risen above a start level, then playback of the video can begin. If the current receive buffer level rises above an early detection threshold, then the video streaming device is requested to slow its streaming rate. If the current receive buffer level rises above a high level threshold, then the video streaming device is requested to stop streaming the video. If the current receive buffer level drops below a low level threshold, then the playback frame rate is slowed.
