Abstract

Divers modes de réalisation concernent des procédés, des appareils, et des produits-programmes informatiques. Un appareil donné à titre d'exemple comprend au moins un processeur ; et au moins une mémoire stockant des instructions qui, lorsqu'elles sont exécutées par le ou les processeurs, amènent l'appareil au moins à : sélectionner une première trame comme étant une trame de point d'accès aléatoire (RAP) ; définir un drapeau RAP d'unité de flux binaire ouvert (OBU) égal à une première valeur pour des OBU dans une unité temporelle de la première trame ; définir un type de trame en tant que trame clé dans un en-tête de trame de la première trame ; et coder la première trame en tant que trame intra.
