A normalize score for evaluating customer perceived quality

摘要

This paper proposes an S-model to normalize the parameters measured from MPEG TS [1][2]. Using the additive normalized scores, an overall assessment score of the quality customer perceived is derived. This paper also provides a systematic approach to calculate the coefficients used in this model. This model has been applied to the actual operational environment, not only to detect the streaming quality, but also to provide quality trend analysis and degradation area judgment.
