Patent

CA 2255925

A BTSC encoder (200) includes a left digital high pass filter (212) for receiving a digital left channel audio signal (L) and generating a digital left filtered signal; a right digital high pass filter (214) for receiving a digital right channel audio signal (R) and generating a digital right filtered signal; a matrix includes an adder (216) for summing the digital left and right filtered signals and generating a digital sum signal (L+R), and including a subtractor (218) for subtracting one of the digital left and right filtered signals from the other of the digital left and right filtered signals and generating a digital difference signal (L- R); a difference channel processor (230) for digitally processing the digital difference signal (L-R); and a sum channel processor (220) for digitally processing the digital sum signal (L+R).

La pésente invention concerne un codeur de standard BTSC (200) qui comprend un filtre passe-haut numérique gauche (212) destiné à recevoir un signal numérique audio de voie gauche (G) et à produire un signal numérique gauche filtré; un filtre passe-haut numérique droit (214) destiné à recevoir un signal numérique audio de voie droite (D) et à produire un signal numérique droit filtré; une matrice comprenant un additionneur (216) qui fait la somme des signaux numériques filtrés gauche et droit et qui produit un signal somme numérique (G+D), et un soustracteur (218) qui soustrait le signal numérique filtré gauche ou droit de l'autre signal numérique filtré et qui produit un signal différence numérique (G-D); un processeur de voie différence (230) qui assure le traitement numérique du signal différence numérique(G-D); et un processeur de voie somme (220) qui assure le traitement numérique du signal somme numérique (G+D).
