NTSC co-channel interference is reduced in an HDTV receiver by developing an interference signal that is representative of the high energy components in the NTSC signal and subtracting the interference signal from the received HDTV signal to produce an enhanced HDTV signal for processing.

Le brouillage dans le même canal NTSC est réduit dans un récepteur TVHD en créant un signal brouilleur représentatif des éléments à haute énergie d'un signal NTSC, puis en soustrayant le signal brouilleur du signal TVHD reçu pour produire un signal TVHD amélioré pour fins de traitement.
