摘要:
Die Patentanmeldung betrifft ein TV-Empfangsteil mit einem steuerbaren Eingangsfilter (FI) zum Unterdrücken von Störleistung in einem Eingangskreis (I HF ) einer HF-Abstimmeinheit (TUN) verursacht durch Sendespektren von terrestrisch empfangenen Funkdiensten und löst ein Problem, welches dadurch entsteht, dass in wenigstens einem Frequenzunterband (beispielsweise von 791 MHz bis 821 MHz) schrittweise ein Betrieb von weiteren Funkdienstarten über die bisherige Nutzung für terrestrische Fernsehfunkdienste oder Kabelfernsehen hinaus zugelassen ist. Gemäß der Aufgabe sind die im TV-Empfangsteil enthaltenen Eingangsfilter (FI) an den sich ändernden Status einer regionalbedingten aktuellen Empfangssituation anzupassen. Das TV-Empfangsteil enthält eine Steuereinrichtung (CTRL) und das Eingangsfilter (FI) zum frequenzselektiven Unterdrücken von Sendeleistung aus Sendespektren in einem Frequenzunterband. Das TV-Empfangsteil nutzt Analyseroutinen, welche die folgenden Merkmale aufweisen: Die Steuereinrichtung führt mit der Abstimmeinheit (TUN) Sendersuchläufe im entsprechenden Frequenzunterband zum Auffinden von Sendespektren aus. Erkennungsmittel für eine Dienstarterkennung bestimmen im Frequenzunterband die aktuelle Empfangssituation in der Empfangsregion anhand eines für selektierte Sendespektren benutzten Übertragungsstandards. Die Steuereinrichtung steuert das Eingangsfilter abhängig von der aktuellen Empfangssituation alternativ in Einstellzustände, die einen Durchlasszustand beziehungsweise einen frequenzselektiven Sperrzustand umfassen.

The present invention discloses a tuning circuit that includes a first band-pass filter that passes a first predetermined frequency band corresponding to the selected channel in the broadcast signal, a mixing circuit that generates a mixed signal by mixing a signal having a predetermined frequency band corresponding to the selected channel with the broadcast signal passed through the first band-pass filter, and a second band-pass filter that passes a second predetermined frequency band in the mixed signal. At least one of a first frequency of the first band-pass filter and a second frequency of the second band-pass filter of the selected channel is changed. The present invention provides a receiver that can improve a quality of the output signal. By using the tuning circuit for a receiver, a quality of the output signal can be improved.
