Title (EN) APPARATUS AND METHOD FOR PROCESSING A PILOT SIGNAL
(FR) APPAREIL ET PROCEDE DE TRAITEMENT D'UN SIGNAL PILOTE
Abstract: front page image
(EN)An apparatus (100) such as a television signal receiver processes a pilot signal to enable, among other things, proper generation of an L-R stereo difference signal. According to an exemplary embodiment, the apparatus (100) includes a signal source (702) operative to provide a pilot signal, and a processing circuit (704-724) operative to process the pilot signal to generate a first processed pilot signal having an AC component and a DC component. The processing circuit (704-724) uses the DC component to control a signal parameter of the AC component and generate a second processed pilot signal that may be used to generate the L-R stereo difference signal.
(FR)L'invention concerne un appareil (100), par exemple un récepteur de signaux télévisuels, qui traite un signal pilote afin de faciliter notamment la génération appropriée d'un signal de différence stéréo G-D. Dans le mode de réalisation selon l'invention, l'appareil (100) comporte une source de signaux (702) destinée à produire un signal pilote, et un circuit de traitement (704-724) destiné à traiter le signal pilote de façon à générer un premier signal pilote traité ayant un composant CA et un composant CC. Le circuit de traitement (704-724) utilise le composant CC pour commander un paramètre de signal du composant CA et générer un second signal pilote traité susceptible de servir à générer le signal de différence stéréo G-D.
