Abstract

Parmi des données représentant une partie centrale principale de trames contenues dans des données numériques constituant un signal téléciné, on forme des premières données de signal vidéo numériques HD de manière à avoir une partie de ligne valable là où les données de rangées de mots dépendant d'une première partie des données précitées sont disposées, et on forme des secondes données de signal vidéo numériques HD de manière à avoir une partie de ligne valable là où les données de rangées de mots d'après une seconde partie des données précitées sont disposées. Les premières et secondes données de signal vidéo numériques HD sont converties en données numériques en série et transmises.
