Abstract
La présente invention a pour objet un procédé et un dispositif de filtrage des sections utiles d'un flux de données émises sous forme numérique. Le procédé consiste à ajouter à la tête des fragments (15) correspondant chacun à une partie d'une section (13) située dans un paquet (9) unique un en-tête (16) de fragment indiquant la position dudit fragment dans la section, le numéro du filtre ayant filtré la section, et le 'PID' ayant traité le paquet contenant le fragment, tous les fragments utiles étant envoyés à l'utilisateur à la fin de chaque paquet de façon à ne pas nécessiter de mémoire de stockage temporaire dans le bloc de filtrage. L'invention se rapporte d'une manière générale au domaine de la réception d'informations numériques transmise par un réseau de télécommunications et utilisant le codage par 'paquets' constitués d'un ensemble de données acheminées en blocs, et plus particulièrement des diffusions émises selon le protocole MPEG 2.
