Abstract

Procédé de transmission de porteuse couleur et d'impulsions de synchronisation à plusieurs caméras de télévision en couleurs à synchronisation extérieure selon la norme CCIRPAL Dans ce procédé, un signal de synchronisation complexe, exclusivement constitué par le mélange de trois signaux individuels, à savoir la porteuse couleur F, une impulsion au double de la fréquence de lignes 2H et une impulsion de retour X au quart de la fréquence verticale, est transmis aux caméras à synchronisation extérieure, signal dont sont alors tirés dans les caméras tous les signaux de commande nécessaires.
