A method of formatting a digital broadcast transport stream packet, a digital broadcast transmitter, and a signal processing method thereof, includes constructing a transport stream packet that includes a stuffing region for an insertion of a known supplementary reference s equence (SRS) data therein, randomizing the packet that includes the stuffing region is randomized, and the SRS data is inserted into the stuffing region of the randomized packet. Adding a parity for an error correction to the packet into which the SRS data has been inserted, the packet to which the parity has been added is interleaved, and a trellis encoding of the interleaved packet is performed. Inserting a segment sync signal and a field sync signal into the trellis- encoded packet, and a vestigial side band (VSB) modulation and an RF conversion of the packet are performed to transmit the VSB-modulated and RF- converted packet.
L'invention porte sur un procédé de formatage d'un paquet de transport de flux d'émissions en numérique, d'un émetteur d'émissions en numérique, et de la méthode de traitement des signaux associée. Ledit procédé consiste: à créer un paquet de transport de flux comportant une zone de remplissage permettant d'y introduire des données de séquence de référence supplémentaire (SRS); à aléatoiriser ledit paquet; à introduire les données SRS dans la zone de remplissage dudit paquet; à ajouter audit paquet une parité de correction d'erreurs; à entrelacer le paquet auquel on a ajouté une parité de correction d'erreurs; à effectuer un codage en treillis du paquet entrelacé; à insérer dans le paquet codé en treillis un signal de synchronisation de segments et un signal de synchronisation de champ; à effectuer une modulation à bande latérale résiduelle (VSB) et une conversion RF du paquet; puis à transmettre le paquet ainsi modulé et converti.
