A method of processing a digital broadcasting signal includes generating a transport stream including a plurality of transport packets; selecting one of the transport packets as a starting packet to be mapped into a first data segment of an encoded data frame; and constructing deterministic data frames in the transport stream beginning with the starting packet; wherein at least one of the 52 transport packets does not have an adaptation field; wherein all remaining ones of the 52 transport packets do have an adaptation field; and wherein the at least one transport packet that does not have an adaptation field is provided at a fixed location in each of the slices.

La présente invention concerne un procédé de traitement d'un signal de diffusion numérique. Ce procédé consiste à générer un flux de transport comportant une pluralité de paquets de transport; à sélectionner l'un au moins des paquets de transport comme paquet de départ à mettre en correspondance dans un premier segment de données d'une trame de données codée; et à construire des trames de données déterministes dans le flux de données commençant par le paquet de départ. En l'occurrence, l'un au moins des 52 paquets de transport ne comporte pas de zone d'adaptation, alors que tous les autres des 52 paquets de transport ont vraiment une zone de transport. Enfin, le paquet de transport démuni de zone d'adaptation est fourni à une emplacement fixé dans chacune des tranches.
