A method for processing a 3D video signal and a digital broadcast receiver for performing the method are disclosed. The method for processing a 3D video signal includes receiving a digital broadcast signal including a multiple hierarchy descriptor, identifying at least one of a second dependent Elementary Stream (ES) based on a first field included in the multiple hierarchy descriptor, wherein the second dependent ES is to be accessed before decoding of a first dependent ES, identifying signaling information of the second dependent ES based on a second field included in the multiple hierarchy descriptor, decoding the first dependent ES and the second dependent ES, and outputting a three dimensional (3D) video signal by formatting the decoded first and second dependent ESs.

Procédé de traitement d'un signal vidéo 3D et récepteur de diffusion numérique correspondant. Ce procédé de traitement d'un signal vidéo 3D consiste : à recevoir un signal de diffusion numérique comprenant un descripteur pluri-hiérachique; à identifier au moins un second flux élémentaire dépendant (ES) sur la base d'un premier champ inclus dans le descripteur pluri-hiérarchique, l'accès au second ES dépendant devant se faire avant le décodage d'un premier ES dépendant; à identifier des informations de signalisation du second flux élémentaire dépendant sur la base d'un second champ inclus dans le descripteur pluri-hiérachique; à décoder le premier ES dépendant et le second ES dépendant; et à émettre un signal vidéo tridimensionnel (3D) par formatage des premier et second ES dépendants.
