(FR) DÉCODEUR, ENCODEUR, PROGRAMME INFORMATIQUE, ET PROCÉDÉ
Abstract:
(EN) A broadcast decoder operable in a low power mode and a high power mode, comprising circuitry configured to: receive physical layer data in the low power mode; detect a parameter in the physical layer data, and in the event of a positive detection of the parameter, the circuitry is further configured to: determine delay data; switch the broadcast decoder to operate in the high power mode at a specified time after detection of the parameter, the time being defined by the delay data; and trigger an alert.
(FR) L'invention concerne un décodeur de diffusion utilisable dans un mode de basse puissance et un mode de haute puissance, comprenant de la circuiterie configurée pour : recevoir des données de couche physique dans le mode de basse puissance ; détecter un paramètre dans les données de couche physique, et en cas de détection positive du paramètre, la circuiterie est aussi configurée pour : déterminer des données de retard ; faire passer le fonctionnement du décodeur de diffusion en mode de haute puissance à un instant spécifié après la détection du paramètre, l'instant étant défini par les données de retard ; et déclencher une alerte.
