(EN) RECEIVER AND PACKET FORMATTER FOR DECODING AN ATSC DTV SIGNAL
(FR) RECEPTEUR ET FORMATEUR DE PAQUETS POUR LE DECODAGE D'UN SIGNAL DE TELEVISION NUMERIQUE ATSC
Abrégé
(EN)
A packet formatter for use in a television receiver capable of receiving a dual bitstream signal comprising a standard stream compatible with the Advanced Television Systems Committee (ATSC) standard and a robust stream. The packet formatter comprises: 1) a first processing block capable of receiving the dual bitstream signal and removing therefrom header bits and parity bits associated with the robust stream to thereby produce a first output signal; and 2) a second processing block capable of receiving the first output signal and removing therefrom duplicate bits associated with the robust stream to thereby produce a second output signal that is output from a data path output of the packet formatter.
(FR)
Formateur de paquets destiné à être utilisé dans un récepteur de télévision capable de recevoir un signal à deux trains de bits composés d'un train de bits standard compatible avec la norme ATSC et d'un train de bits robuste. Le formateur de paquets comporte: 1) un premier bloc processeur capable de recevoir le signal à deux trains de bits et d'en extraire les bits d'en-tête et les bits de parité associés au train de bits robuste pour produire un premier signal de sortie; et 2) un second bloc processeur capable de recevoir le premier signal de sortie et d'en extraire des bits dupliqués associés au train de bits robuste pour générer un second signal de sortie au niveau d'une sortie de chemin de données du formateur de paquets.
