Abstract
Systems, methods and apparatus are provided for computing quality scores for a media session delivered using an adaptive streaming protocol, where the quality score may be an estimate of a mean opinion score. The quality score reflects the impact of network delivery on a viewer's quality of experience (QoE). In particular, the quality score is generally based on the effects of stream switch events, as stream switches may be the result of impaired network delivery. Other network events, such as re-buffering events may also be incorporated in the score.
