- METHOD FOR REDUCING PRE-FETCHING OF MULTIMEDIA STREAMING DATA WITH MINIMAL IMPACT ON PLAYBACK USER EXPERIENCE

摘要

The systems, methods, and devices of various embodiments may be configured such that the receiver device determines a high watermark margin and a low watermark margin for the cache based on data associated with the selected media instance, and the determined high watermark margin and low watermark And to control the downloading of portions of the media instance based at least in part on the margins. The high watermark margin and low watermark margin may be determined based on the playback rate and high watermark margin time value and low watermark margin time value of the media instance, respectively. The low watermark margin may be determined based on the rate of change in the buffered portions of the media instance, and the high watermark margin may be determined based on the determined low watermark margin and the playback rate.;
