Abrégé
(EN)
A digital broadcast system is disclosed. Particularly, the present invention is advantageous in that supplementary data having information included therein or supplementary information having patterns generated under a mutual agreement between transmitting/receiving ends are included in an adaptation field within a transport stream packet and then transmitted. Thusr the present invention may be highly compatible to the conventional receiving system. Furthermore, when using the supplementary data having information included therein, additional encoding is performed on the supplementary data, which are then transmitted- Thus, a channel with severe ghost effect and noise may also receive the supplementary data without any errors.

L'invention concerne un système de télédiffusion numérique. Elle est plus particulièrement avantageuse en ce que des données complémentaires incluant des informations, ou des informations complémentaires contenant des motifs générés d'un commun accord entre des terminaux d'émission et de réception, sont insérées dans un champ d'adaptation contenu dans un paquet de flux de transport, puis transmises. La présente invention s'adapte donc parfaitement au système de réception classique. En outre, en cas d'utilisation des données complémentaires incluant des informations, un processus de codage supplémentaire est appliqué aux données complémentaires, qui sont ensuite transmises. Un canal présentant d'importants effets d'écho et de bruit peut donc également recevoir les données complémentaires sans erreur.
