Abstract

The radio receiver has a programme selection switch selecting tuning signals stored in a memory. Other memories store the operating states of other subassemblies in the receiver and are also addressed by the selection switch when the tuning signals are selected. The operating states stored in these other memories are the state of the stereo decoder (mono/stereo) a dynamic-range expander (on/off) and a noise suppression circuit (on/off). The advantage lies in making it easier for the user to obtain the same conditions when he selects a programme for the second time - i.e. the parameters are the same.

Description

Rundfunkempfänger mit einer Speicher- und Programmwahl-Radio receiver with a memory and program selection

schalteranordnung Zur Erleichterung der Bedienung eines Ton- oder Fernseh-Rundfunkempfängers ist es bekannt, die Abstimmgrö3en Cz.switch arrangement To facilitate the operation of a sound or Television radio receiver it is known to tune the tuning sizes Cz.

B. Abstimmspannungen für die Xapazitätsdioden des Tuners) für eine Reihe von bestimmten Sendern zugeordneten Frequenzen zu speichern und über Programmwahlschalter die schnelle Einstellung eines vorher eingespeicherten Senders zu ermöglichen.B. tuning voltages for the Xapacitance diodes of the tuner) for a Save a number of frequencies assigned to certain stations and use the program selector switch to enable the quick setting of a previously stored transmitter.

Neben der Abstimmung des Senders sind in der Regel noch einige weitere Einstellungen erforderlich, wie z.B. Einstellung der Lautstärke und gegebenenfalls Höhen- und Tiefeneinstellung, Wahl ob Stereo- oder Monowiedergabe oder Ein- und Ausschalten eines Expanders bei Übertragung von in der Dynamik komprimierten Programmen bzw. eines Rauschunterdrückungssystems. Ein Optimum an Bedienungskomfort ist also allein durch Programmwahlschalter, die nur den Sender auswählen, nicht gegeben. Darüber hinaus besteht die Möglichkeit, daß eine mit der Bedienung des Rundfunkempfängers nicht so vertraute Person die optimale Einstellung nicht oder erst nach längerem Probieren findet.In addition to tuning the station, there are usually a few more Settings required, such as setting the volume and, if necessary Treble and bass setting, choice of stereo or mono playback or input and Switching off an expander when transmitting dynamically compressed programs or a noise reduction system. So an optimum of ease of use is not given solely by program selector switches that only select the station. In addition, there is the possibility that one with the operation of the radio receiver Not so familiar person does not find the optimal setting or only after a long time Try finds.

Die der Erfindung zugrunde liegende Aufgabe besteht darin, den Bedienungskomfort eines Rundfunkempfängers gemäß dem Oberbegriff des Patentanspruchs 1 zu verbessern. Diese Aufgabe wird durch die im Kennzeichen des Patentanspruchs 1 angegebenen Erfindung gelöst. Eine Weiterbildung ist in einem Unteranspruch angegeben.The object on which the invention is based is to improve ease of use a radio receiver according to the preamble of claim 1 to improve. This object is achieved by the invention specified in the characterizing part of claim 1 solved. A further development is specified in a sub-claim.

Die Erfindung wird nun im einzelnen erläutert. Die Erfindung geht von der Erfahrung aus, daß die bei einem Rundfunkempfänger vorhandenen Einstellmöglichkeiten nicht ständig varriert werden, sondern daß vielmehr eine bestimmte für einen speziellen Sender als optimal herausgefundene Einstellung für diesen Sender immer wieder vorgenommen wird.The invention will now be explained in detail. The invention works from experience that the setting options available in a radio receiver are not constantly varied, but rather that a certain one for a special one Transmitter as the optimally found setting for this transmitter again and again will.

Die Einstellung kann also durchaus von einem Sender zum anderen unterschiedlich sein. So ist es denkbar, bei Sendern, die an sich Stereoprogramme ausstrahlen, die Umschaltung des Stereodecoders auf "Mono" vorzunehmen, um einen besseren Signal-Rausch-Abstand zu erhalten. Häufig wird nun z.B. vergessen, bei anderen Sendern diese Mono-Schaltung wieder rückgängig zu machen, wodurch unnötigerweise ein guter Stereo-Sender nur in Mono empfangen wird.The setting can therefore vary from one station to another be. So it is conceivable for stations that broadcast stereo programs that Switch the stereo decoder to "Mono" to achieve a better signal-to-noise ratio to obtain. Often people forget, for example, to use this mono switch on other transmitters Undo, unnecessarily making a good stereo station only is received in mono.

Ein weiteres mit dem Empfang eines bestimmten Senders verbundenes Merkmal besteht in der Ausstrahlung von in der Dynamik komprimierten Programmen, zu deren Decodierung die Einschaltung eines Dynamik-Expanders erforderlich ist.Another one associated with the reception of a particular station Feature consists in the broadcasting of dynamically compressed programs, for the decoding of which the activation of a dynamic expander is required.

Dieses letztere Merkmal hat sogar die Eigenschaft, daß das Vorhandensein eines Dynamik-Kompressors auf der Senderseite in einer Programmpause oder bei Ubertragung von Darbietungen mit kleinem Dynamikbereich nicht sofort bemerkt wird.This latter characteristic even has the property that the presence a dynamic compressor on the transmitter side during a program break or during transmission is not immediately noticed by performances with a small dynamic range.

Durch eine auf den Sender bezogene Voreinstellung des Stereodecoders und des Expanders wird so eine Fehlbedienung oder wenigstens eine von der optimalen Bedienung abweichende vermieden. Gleichzeitig erhöht sich der Bedienungskomfort, da diese Einstellungen bei der Senderwahl gar nicht mehr ausgeführt zu werden-brauchen. Zur Speicherung der Betriebszustände dienen Speicher, die mit dem Programmwahlschalter in der gleichen Weise adressiert werden wie die Speicheranordnungen für die Speicherung von Abstimmgrößen. Durch Mittel zur Voreinstellung werden dann im Rahmen einer Vorprogrammierung der Programmwahlschalter auf bestimmte Sender diese Merkmale einmalig mit eingespeichert.By presetting the stereo decoder based on the station and the expander thus becomes a mistake or at least one of the optimal ones Deviating operation avoided. At the same time, the ease of use increases, since these settings are no longer at all when selecting a station executed to become-need. Memories with the program selector switch can be addressed in the same way as the memory arrays for storing voting parameters. Presetting means are then used as part of a pre-programming of the program selector switch for certain channels these features are saved once.
