Description

Pour chaque média temporel seulement son, seulement vidéo ou synchronisé, le contenu textuel adjacent permet-il d’identifier clairement le média temporel (hors cas particuliers) ?

Particular cases (criterion 4.7)

Il existe une gestion de cas particulier lorsque le média temporel est utilisé à des fins décoratives (c’est-à-dire qu’il n’apporte aucune information). Dans cette situation, le critère est non applicable.
