Circuit and method for determining a received signal for a receiver such as a simulcast receiver or an HDTV receiver are provided. The circuit includes a first detector for detecting a first reference signal included in a received signal and outputting a first detection signal, a second detector for detecting a second reference signal included in the received signal and outputting a second detection signal, and a generator for generating a determination signal which indicates that the received signal is an analog broadcasting signal, if the first detection signal is detected, and indicates that the received signal is a high definition signal, if the second detection signal is detected. Therefore, the received signal can be determined correctly, according to channel selection.
Circuit et méthode de détermination d'un signal reçu par un récepteur, p. ex. un récepteur de diffusion simultanée ou TVHD. Le circuit comprend un premier détecteur pour détecter un premier signal de référence compris dans un signal reçu et produire un premier signal de détection; un deuxième détecteur pour détecter un deuxième signal de référence compris dans le signal reçu et produire un deuxième signal de détection; et un générateur pour générer un signal de détermination qui indique que le signal reçu est un signal de radiodiffusion analogique, si le premier signal de détection est détecté, et que le signal reçu est un signal TVHD si le deuxième signal de détection est détecté. Il est ainsi possible de déterminer correctement le signal reçu, conformément au choix de canal.
