Abstract

L'invention concerne un système de distribution vidéo (par exemple un système de diffusion par câble) comprenant un point de distribution en amont (par exemple une extrémité de tête de câble), une voie de communications (par exemple un câble) et un ou plusieurs points d'extrémité (par exemple un boîtier numérique). L'extrémité de tête du câble transmet un canal de programme en aval le long d'une partie redondante du canal de programme vers le boîtier numérique dans une première bande de fréquence. Le boîtier numérique lit le contenu associé au canal de programme et utilise la partie redondante du canal de programme, de manière à acheminer une durée temporelle, lors de laquelle le syntoniseur du boîtier numérique est syntonisé sur une autre bande de fréquences, par exemple un canal hors bande.
