Abstract

Procédé de synchronisation séparée d'un rythmeur de télévision en couleurs selon la norme CCIR-PAL. Ce procédé est remarquable en ce qu'on utilise pour la synchronisation un signal d'entrée composite de couleur, d'image, de suppression de faisceau et de synchronisation provenant d'une caméra de télévision en couleurs du réseau de radiodiffusion de télévision, ou bien d'un magnétoscope, en ce qu'on sépare de ce signal d'entrée composite, d'une manière connue en soi des impulsions horizontales 11 et verticales 8 ainsi que la salve de synchronisation 40, en ce que la salve 40 et les impulsions horizontales 11 règlent, par l'intermédiaire de circuits de comparaison de phases 2,12 des oscillateurs de référence 4,13, qui engendrent la porteuse couleur F et une fréquence double de la fréquence horizontale 2 fH , ou par l'intermédiaire d'un diviseur de fréquence 17, des impulsions horizontales et verticales et en ce que le diviseur de fréquence 17 est actionné par une impulsion de retour 15 spécialement engendrée à cet effet, qui contient l'information de coordination correcte des trames et de phase de commutation PAL.Method of separate synchronization of a color television clock according to the CCIR-PAL standard. This method is remarkable in that a composite input signal of color, image, beam suppression and synchronization from a color television camera of the television broadcasting network is used for synchronization, or well of a video tape recorder, in that one separates from this composite input signal, in a manner known per se, horizontal 11 and vertical 8 pulses as well as the synchronization burst 40, in that the burst 40 and the horizontal pulses 11 adjust, via phase comparison circuits 2.12, reference oscillators 4.13, which generate the color carrier F and a frequency twice the horizontal frequency 2 fH, or via a frequency divider 17, horizontal and vertical pulses and in that the frequency divider 17 is actuated by a specially generated feedback pulse 15, which contains the correct coordination information of the frames and PAL switching phase.
