Abstract

L'invention concerne la télédistribution. Un disque 25 qui constitue une matrice de programmation à codage optique tourne sous la dépendance d'un détecteur de synchronisation 90 qui est attaqué par un circuit d'horloge 55. Le lecteur optique 120 commande le commutateur SW1 par l'intermédiaire d'une mémoire 105 et d'un comparateur 110. Application aux réseaux de télédistribution comportant un grand nombre de stations émettrices.
