Abstract
Procédés et dispositifs de contrôle de transmission d’un flux vidéo Procédé de contrôle de transmission d’un flux vidéo comprenant des images (50) séparées par des intervalles de rafraîchissement (52), caractérisé en ce que ledit procédé de contrôle de transmission comprend les étapes suivantes mises en œuvre par un bloc électronique de contrôle suite à la réception, par un récepteur électronique, du flux vidéo transmis : pour chaque image d’un ensemble d’images successives dans le flux vidéo reçu, capture de la valeur d’au moins un bit à une position prédéfinie (31) dans l’intervalle de rafraîchissement succédant à ladite image reçue ;comparaison d’une séquence prédéfinie de valeurs avec la séquence desdites valeurs déterminées pour l’ensemble d’images et ordonnées en fonction de la succession desdites images dans l’ensemble ;détection d’une anomalie de transmission en fonction de ladite comparaison.
