Abstract[English]
Methods and systems for two-dimensional (2D) coding are described for broadcast, multicast or groupcast applications. Two or more information code blocks (CBs) are transmitted to a plurality of intended receiving nodes. One or more cross-CB check blocks are generated, each cross-CB check block being generated based on a set of cross-CB bits, the set of cross-CB bits including at least one bit selected from each of at least two of the information CBs. At least one cross-CB check block is transmitted to at least one of the intended receiving nodes.[French]
L'invention concerne des procédés et des systèmes de codage bidimensionnel (2D) destinés à des applications de diffusion générale, de multidiffusion ou de diffusion en groupe. Au moins deux blocs de code (CB) d'information sont transmis à une pluralité de nœuds de réception prévus. Un ou plusieurs blocs de contrôle inter-CB sont générés, chaque bloc de contrôle inter-CB étant généré d'après un ensemble de bits inter-CB, l'ensemble de bits inter-CB incluant au moins un bit sélectionné parmi chaque CB d'au moins deux des CB d'information. Au moins un bloc de contrôle inter-CB est transmis à au moins un des nœuds de réception prévus.
