Abstract: front page image
(EN)A device and method are provided for implementing digital baseband separation of composite video signals with reduced memory requirements. The method and device require that only the composite signal be stored in a large delay element(501, 502). Multiple quadrature demodulators(503) are employed to generate multiple delayed complex baseband signals. Therefore, no large complex baseband delay element is required.
(FR)L'invention concerne un dispositif et un procédé pour mettre en oeuvre la séparation digitale de la bande de base des signaux vidéo composites nécessitant un encombrement mémoire réduit. Le procédé et dispositif nécessitent la stockage du signal composite seul dans un grand élément de retard (501, 502). Des démodulateurs multiples en quadrature (503) sont utilisés pour générer des signaux multiples retardés à bande complexe de base. Ainsi, un grand élément de retard des signaux à bande complexe de base n'est pas nécessaire.
