Parametric audio quality model for IPTV services

摘要

The present invention relates to a method and an apparatus for assessing the quality of an audio signal, and in particular for assessing the quality of an audio signal transmitted by using encoding methods and/or encrypting methods. The method for estimating the perception quality of a decoded audio signal being decoded from an encoded and/or encrypted audio signal comprises the steps of: a) estimating the compression quality impact Icod A due to audio compression; b) estimating the perception quality Q A of the decoded audio signal using the estimations obtained in at least one of the foregoing steps.
