Abstract

Cette invention concerne un procédé et un dispositif qui permettent de définir la qualité de transmission dans un système de transmission. Ce dispositif comprend un système (504) qui va émettre des informations de test pouvant être reconnues sur un canal de transmission. Afin d'obtenir une estimée fiable de la qualité de transmission, le dispositif comprend un système (510) qui va effectuer une mesure des informations afin de révéler si elles sont reconnues ou non par rapport aux informations de test reçues. Ce dispositif comprend également un système (510) qui va mesurer la qualité de transmission à un moment donné en fonction des mesures effectuées sur une période prédéterminée.
