Method For Reducing Pre-Fetching Of Multimedia Streaming Data With Minimal Impact On Playback User Experience

摘要

Systems, methods, and devices of the various embodiments enable a receiver device to determine a high watermark margin and a low watermark margin for a cache based on data associated with a selected media instance and control the download of portions of the media instance based at least in part on the determined high watermark margin and low watermark margin. The high watermark margin and the low watermark margin may be determined based on a playback rate of the media instance and a high watermark margin time value and low watermark margin time value, respectively. The low watermark margin may be determined based on a rate of change in 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.

主权项

1. A method for pre-fetching a media instance on a receiver device, comprising:
determining, in a processor of the receiver device, a high watermark margin and a low watermark margin for a cache of the receiver device based on data associated with a media instance to be downloaded; and controlling, in the processor, download of portions of the media instance to the cache based at least in part on the determined high watermark margin and the determined low watermark margin.
