Abstract

L'invention concerne un système de collage sans solution de continuité de programmes vidéo comprimés. On règle divers paramètres de données de collage afin de pouvoir manipuler ces données en fonction du collage, puis on détermine les points de collage admis, pour les programmes en cours ou suivants, qui sont les plus cohérents par rapport au temps de collage souhaité, de manière à effectuer une transition sans heurt du programme en cours au programme suivant.
