Abstract

L'invention concerne un procédé pour détecter un arrêt ou une pause dans une séquence de trames d'image comprenant la réception d'une séquence de trames, le calcul d'une valeur statique pour des trames de la séquence, l'accès à des données pour des trames comparables, la comparaison de la valeur calculée avec les données des trames comparables, et la production en conséquence d'une sortie pause/arrêt. L'étape de calcul d'une valeur statistique pour des trames de la séquence peut comprendre le calcul de la somme des différences temporelles entre une trame et une trame précédente.
