Abstract

La présente invention concerne un procédé de signalisation d'information de division de signal. Ce procédé de signalisation divise un signal en plusieurs signaux et représente efficacement des informations de division de ces signaux divisés. Cette invention concerne le procédé de signalisation permettant de signaler des informations de division de signal qui consiste à attribuer un nombre de noeuds inférieur ou égal au nombre de divisions à une couche inférieure si un noeud d'une couche supérieure est représenté par un identificateur de division (ID), à annuler l'attribution de n'importe quel noeud inférieure à la couche inférieure si le noeud de la couche supérieure est représenté par un identificateur de non division ( (ID), ces informations de division de signal comprenant l'identificateur de division et l'identificateur de non division indiquant la présence ou l'absence d'une division de signal au niveau d'un noeud d'une couche.:
