Abstract
L'invention concerne un procédé et un système de mise en oeuvre d'une matrice de programmation à temps morts réduits (520) pour un fichier de données mis sous forme de blocs de données. On génère une matrice de programmation et les temps morts sont remplis avec des blocs de données qui apparaissent plus tard dans la matrice, en gardant la séquence originale des blocs de données. Ce processus est répété (550), ou bien il est procédé à la création d'une nouvelle matrice de programmation à temps morts réduits (560). Des décodeurs spécialement conçus permettent de recevoir ces blocs de données.
