Abstract

L'invention concerne un procédé servant à détecter la qualité d'un service multidiffusé, un terminal en ligne optique et une unité de réseau optique. Dans le procédé : un terminal en ligne optique sélectionne un ou plusieurs groupes de multidiffusion dédiés à la surveillance, et envoie des paramètres caractéristiques du groupe de multidiffusion à une unité de réseau optique désignée ; le terminal en ligne optique envoie un paquet de jonction multidiffusé du groupe de multidiffusion dédié à la surveillance à une source de multidiffusion, et à réception d'un flux de service multidiffusé de surveillance qui correspond au paquet de jonction multidiffusé et est envoyé par la source de multidiffusion, envoie le service multidiffusé de surveillance à l'unité de réseau optique désignée ; et à réception du flux de service multidiffusé de surveillance, l'unité de réseau optique désignée détecte la qualité du service multidiffusé de surveillance en fonction des paramètres caractéristiques du groupe de multidiffusion dédié à la surveillance. Selon la présente invention, la qualité de la vidéo multidiffusée fournie à un utilisateur peut être surveillée dans le temps.
