ABSTRACT:
Systems and methods for managing frame rates during multimedia playback are described herein. The ideal playback timing associated with video data is determined. If an actual playback timing of the video data lags the ideal playback timing, a frame rate associated with the video data is varied using a smoothing function to recover toward the ideal playback timing. An iterative frame-dropping algorithm is applied to vary the frame rate in accordance with the smoothing function. The smoothing function incorporates as a variable an average delay associated with playback of frames in the video data.
