Bandwidth Estimation Based on Statistical Measures

摘要

Some embodiments provide a method for estimating bandwidth estimate based on a set of statistical measurements that quantifies bandwidth variation. The method receives a piece of media content at a receiving device and computes several instantaneous bandwidth measurements based on sample data blocks or media content received at the receiving device. The method computes the set of statistical measures that quantifies variation between the computed instantaneous bandwidth measurements. Based on the set of statistical measures, the method computes a revised bandwidth estimate for receiving media content at the receiving device. In some embodiments, the method uses the revised bandwidth estimate to determine an amount of media content data to buffer in order to provide an uninterrupted playback.
