| Méthodes d'évaluation subjective de la qualité de transmission |
 |
La présente Recommandation décrit des méthodes et des procédures permettant d'effectuer des évaluations subjectives de la qualité de transmission. La principale révision reprise dans cette version de la Recommandation a consisté à ajouter une annexe décrivant la procédure d'évaluation par catégories de comparaison (CCR, comparison category rating). D'autres modifications ont été apportées pour aligner la présente Recommandation sur la révision récente de la Recommandation P.830. |
