Patent

CA 2209744

In developing a receiver used for both 8-VSB system and 16-VSB system based upon the fact that there are so many common modulation parts which are commonly operated between the two systems, an operation mode is automatically switched by using the autocorrelation for operation modes of the received data without manual operation, and signals for controlling the entire system can be outputted, thereby recalizing efficiency and economy in operating the HDTV receiver.

Dans l'élaboration d'un récepteur utilisé dans les systèmes 8-VSB et 16-VSB, cette élaboration étant basée sur le fait que ces deux systèmes utilisent de nombreux éléments de modulation communs, un mode de fonctionnement est commuté automatiquement au moyen d'une autocorrélation des modes d'exploitation des données reçues sans opérations manuelles, et des signaux de commande pour le système tout entier peuvent être produits, ce qui augmente l'efficacité et permet de réaliser des économies dans l'utilisation du récepteur de TVHD.
