Pre-Buffering Audio Streams

摘要

One embodiment of the present invention sets forth a technique for identifying and pre-buffering audio/video stream pairs. The method includes the steps of predictively identifying for pre-buffering at least one audio/video stream pair that may be selected for playback by a user subsequent to a currently playing audio/video stream pair, computing a first rate for pre-buffering an audio portion of the at least one audio/video stream pair and a second rate for pre-buffering a video portion of the at least one audio/video stream pair, downloading the audio portion at the first rate and downloading the video portion at the second rate, and storing the downloaded audio portion and the downloaded video portion in a content buffer.

1. A computer-implemented method, comprising:
sampling a plurality of performance characteristics associated with a streaming video service while streaming media content to one or more of users; for each performance characteristic included in the plurality of performance characteristics, determining a numerical contribution the performance characteristic makes to a single quality of experience (QoE) metric for the streaming video service; correlating the single QoE metric with a measure of user engagement to determine a plurality of weights, wherein each weight corresponds to the numerical contribution determined for a different performance characteristic; generating a computed single QoE metric based on the numerical contributions determined for the plurality of performance characteristics and the plurality of weights; and updating at least one configuration setting for the streaming video service based on the computed single QoE metric.
