Abstract
The invention relates to a device and method for reproducing digital receiver signals. The claimed invention provides the user with a conventional radio receiver having a universal and comfortable operational concept for reproducing digital receiver signals.
Description
Vorrichtung und Verfahren zur Darstellung von digitalen Empfangssignalen Apparatus and method for displaying digital received signals
Die vorliegende Erfindung betrifft eine Vorrichtung und ein Verfahren zur Darstellung von digitalen Empfangssignalen. Durch die vorliegende Erfindung wird dem Bediener eines herkömmlichen Rundfunkempfängers ein universelles und komfortables Bedienkonzept zur Darstellung von digitalen Empfangssignalen an die Hand gegeben. The present invention relates to an apparatus and a method for displaying digital received signals. The present invention provides the operator of a conventional radio receiver with a universal and comfortable operating concept for displaying digital received signals.
Herkömmliche Rundfunkempfänger in Fahrzeugen sind im Allgemeinen lediglich für den Empfang analoger Rundfunksignale vorgesehen, nicht jedoch für digitale Rundfunksignale, insbesondere DRM und DAB. Ein Austausch der in großer Zahl vorhandenen analogen Rundfunkempfänger ist jedoch kostspielig und aufwendig, so dass digitale Rundfunksendungen bisher nur selten von Fahrzeugen empfangen werden können. Conventional radio receivers in vehicles are generally intended only for the reception of analog broadcast signals, but not for digital broadcast signals, in particular DRM and DAB. However, replacing the large number of existing analog radio receivers is costly and expensive, so that digital broadcasts so far can rarely be received by vehicles.
Komplettgeräte für den analogen und digitalen Empfang für mobile Verkehrsteilnehmer sind derzeit noch ausreichend nicht verfügbar und werden nach erfolgter Entwicklung zunächst oftmals für viele Nutzer in einem ungünstigen Preis-Leistungs-Verhältnis stehen. Complete devices for the analog and digital reception for mobile road users are currently still not sufficiently available and will initially often be for many users after the development in an unfavorable price-performance ratio.
Das der vorliegenden Erfindung zugrundeliegende Konzept der „Interactive RDS Broadcast"-Architektur, im Folgenden auch als IRB -Architektur bezeichnet, basiert auf der Aufgabenstellung gemäß der beim Abspielen und Anzeigen von Audioquellen über einen FM-RDS-Empfänger eine interaktive Kommunikation und Menüführung realisiert werden soll. The concept underlying the present invention of the "interactive RDS broadcast" architecture, also referred to below as the IRB architecture, is based on the problem according to which interactive communication and menu guidance are implemented when playing and displaying audio sources via an FM RDS receiver should.
FM-RDS-Empfänger, die zur Ausführung des erfindungsgemäßen Verfahrens geeignet sind, sind aus dem Stand der Technik - z.B. aus der Europäischen Patentanmeldung 0 333 194 - bekannt. Ein derartiger FM(UKW)-Empfänger wird durch einen Doppeltuner-FM-RDS- Empfänger mit einem ersten oder Haupttuner oder einem zweiten oder Hilfstuner verkörpert. Der Haupttuner dient zum Abstimmen des Empfängers auf eine Rundfunksenderstation mit einem gewünschten Audioprogramm und zum Verarbeiten der Audioprogrammsignale für die Klangwiedergabe. FM-RDS receivers suitable for carrying out the method according to the invention are known in the art - e.g. from European Patent Application 0 333 194 - known. Such an FM (FM) receiver is embodied by a twin tuner FM RDS receiver with a first or main tuner or a second or auxiliary tuner. The main tuner is for tuning the receiver to a broadcast station with a desired audio program and for processing the audio program signals for sound reproduction.
Wenn der empfangene Sender auch RDS-Daten sendet, extrahiert der Haupttuner außerdem die durch das empfangene RDS-Sendersignal geführten RDS-Daten (RDS- Datentelegramm], u.a. auch eine Liste von Alternativfrequenzen (AFs]. Eine solche Liste liefert Abstimmdaten von Senderfrequenzen, die dasselbe Programm führen, wie das, auf das der Empfänger tatsächlich abgestimmt ist. When the received transmitter also transmits RDS data, the master tuner also extracts the RDS data (RDS data telegram) passed through the received RDS transmitter signal, including a list of alternative frequencies (AFs) the same program as the one to which the recipient is actually tuned.

BESTÄTIGUNGSKOPIE
Das Format eines RDS-Datentelegrammes ist in Europa einheitlich. Hierbei werden neben den eigentlichen Rundfunksignalen weitere Informationen übertragen, die von Autoradios die über einen entsprechenden RDS-Decoder verfügen, ausgewertet werden können. So kann beispielsweise der Name des empfangenen Programms auf einer entsprechenden Anzeige bzw. einem Display des Radios angezeigt werden (PS-Code). CONFIRMATION COPY The format of an RDS data telegram is uniform in Europe. In addition to the actual broadcast signals, further information is transmitted here that can be evaluated by car radios which have a corresponding RDS decoder. For example, the name of the received program can be displayed on a corresponding display or display of the radio (PS code).
Zur Lösung der eingangs erwähnten Aufgabe wird die Senderliste des FM-RDS-Empfängers verwendet, um die auswählbaren Audioquellen und/oder Menüfunktionen gleichzeitig darstellen zu können. Wie benutzerfreundlich bzw. komfortabel die Senderliste dargestellt und bedient werden kann, hängt von dem jeweiligen FM-RDS-Empfänger ab. To solve the object mentioned above, the station list of the FM-RDS receiver is used to represent the selectable audio sources and / or menu functions simultaneously. How user-friendly or comfortable the station list can be displayed and operated depends on the respective FM-RDS receiver.
Die Länge der Senderliste wird lediglich durch die mögliche Anzahl empfangsfähiger Sender im UKW-Band begrenzt; sie ist somit unproblematisch und stellt für die Verwirklichung der vorliegenden Erfindung keine Einschränkung dar. The length of the station list is limited only by the possible number of stations capable of transmitting in the FM band; It is therefore unproblematic and does not constitute a restriction for the realization of the present invention.
Die „Interactive RDS Broadcasf'-Architektur basiert von ihrem Grundaufbau her auf folgenden Komponenten: a. Verwalten, sortieren und priorisieren von Audioquellen The "Interactive RDS Broadcasf" architecture is based on the following components from its basic structure: a. Manage, sort and prioritize audio sources
b. Echtzeit MPX-Coder mit FM-Modulator b. Real-time MPX coder with FM modulator
c. Echtzeit Sampleplayer c. Realtime sampleplayer
d. Echtzeit Addierer d. Realtime adder
e. MPX-Coder mit reduziertem RDS-Informationen e. MPX coder with reduced RDS information
f. FM-Modulator f. FM modulator
g. Speicher für die Samples G. Memory for the samples
h. Addierer H. adder
i. Decoder für den Rückkanal i. Decoder for the return channel
Hardwareseitig müssen die nachfolgenden Voraussetzungen erfüllt sein: On the hardware side, the following requirements must be met:
Die FM-modulierten Signale im UKW-Band müssen dem RDS-Empfänger mit einem Pegel von ca. 50 - 70 dBμV dem FM-RDS-Empfänger zur Verfügung gestellt werden. - Die NF(Niederfrequenz)-Ausgänge des FM-RDS-Empfängers sind digitalisiert, bzw. das ZF- Signal (Zwischenfrequenzsignal) des FM-RDS-Empfängers ist mittels des FM-RDS-
Demodulators decodierbar und kann auf den Softwaredecoder für den Rückkanal gegeben werden. The FM modulated signals in the FM band must be made available to the RDS receiver with a level of approx. 50 - 70 dBμV to the FM RDS receiver. - The LF (low frequency) outputs of the FM RDS receiver are digitized, or the IF signal (intermediate frequency signal) of the FM RDS receiver is digitized using the FM RDS Demodulator decodable and can be given to the software decoder for the return channel.
Die Kommunikation gemäß der erfindungsgemäßen „Interactive RDS Broadcast"- Architektur wird folgendermaßen durchgeführt, wobei zunächst anzumerken ist, dass wenigstens zwei Varianten existieren, nach denen sich die Kommunikation realisieren lässt: The communication according to the "interactive RDS broadcast" architecture according to the invention is carried out as follows, wherein it should first be noted that at least two variants exist according to which the communication can be realized:
1. Variante: Die Zwischenfrequenz wird vom Radio wieder ausgegeben und vom IRB ausgewertet. 1st variant: The intermediate frequency is output by the radio and evaluated by the IRB.
2. Variante: Ins MPX[Multiplex)-Signal wird eine eindeutige Kennung im Audiofrequenzbereich dazugerechnet, welche an den Endstufenausgängen von dem IRB ausgewertet werden kann. 2nd variant: The MPX [Multiplex] signal is assigned a unique identifier in the audio frequency range, which can be evaluated by the IRB at the output stage outputs.
Für alle vorselektierten Audioquellen wird der Name der Audioquelle als PS-Code in das MPX-Signal ohne Audiosignal gerechnet, Frequenz-moduliert und an den FM-RDS- Empfänger übermittelt. Durch die Reduktion des Umfangs des RDS-Protokolls, Zwischenspeichern und Zusammenfassen der FM-Signale kann der technische Aufwand gering gehalten werden. For all preselected audio sources, the name of the audio source is calculated as PS code in the MPX signal without audio signal, frequency modulated and transmitted to the FM RDS receiver. By reducing the scope of the RDS protocol, caching and summarizing the FM signals, the technical complexity can be kept low.
Die resultierende Senderliste zeigt alle PS-Codes - also die Namen der Audioquellen - als „Sender" im FM-RDS-Empfänger an. The resulting channel list displays all PS codes - the names of the audio sources - as "senders" in the FM RDS receiver.
Sobald einer der angezeigten„Sender" vom Bediener ausgewählt wird, empfängt der FM- RDS-Empfänger zunächst den Sender ohne Audiosignal (Stille). Gleichzeitig wird - je nach Variante - das ZF-Signal oder die Audiokennung dem IRB zur Verfügung gestellt. Erkennt nun das IRB einen PS-Code, welcher mit einem momentan aktiven Sender mit einem entsprechenden PS-Code identisch ist, schaltet das IRB auf die ausgewählte Audioquelle bzw. führt die entsprechende Menüfunktion aus. As soon as one of the displayed "stations" is selected by the operator, the FM-RDS receiver first receives the station without an audio signal (silence) and at the same time - depending on the variant - the IF signal or the audio identification is made available to the IRB the IRB switches a PS code which is identical to a currently active transmitter with a corresponding PS code, switches the IRB to the selected audio source or executes the corresponding menu function.
Die„Interactive RDS Broadcasf-Kommunikation hat folgende Vorteile: The "Interactive RDS Broadcasf communication has the following advantages:
Das IRB muss keine Steuerbefehle interpretieren, sondern basiert auf einer konzeptionell statischen Steuerinformation, die ihm vom Bediener gegeben wird. Die Kommunikation zwischen IRB und Bediener ist dadurch eindeutig und stabil. The IRB need not interpret control commands but is based on conceptually static control information given by the operator. The communication between IRB and operator is thereby clear and stable.
Das IRB-Bedienkonzept ist außerdem herstellerunabhängig in jedem FM-RDS-Empfänger realisierbar - beispielweise auch in der häuslichen und mobilen Unterhaltungselektronik.
Darüber hinaus ist für die Durchführung des erfindungsgemäßen IRB-Konzept kein CAN [Controller Area Network) erforderlich und es wird ferner keine Software-Anpassungen hinsichtlich der verschiedenen Fahrzeughersteller benötigt. The IRB operating concept is also vendor-independent in every FM RDS receiver feasible - for example, in the domestic and mobile consumer electronics. In addition, no CAN [Controller Area Network] is required for carrying out the IRB concept according to the invention, and further, no software adjustments are required with regard to the various vehicle manufacturers.
Des Weiteren wird keine Requalifizierung von nachgerüsteten Fahrzeugen erforderlich. Daneben wird kein Bedienelement des originären FM-RDS-Empfängers zweckentfremdet verwendet oder erhält zusätzliche Funktionen. Dies beinhaltet den Vorteil, das eine intuitive Bedienung und Bedienerführung erhalten bleibt und Stationstasten wie im gewohnten Betrieb eingesetzt werden können. Furthermore, no re-qualification of retrofitted vehicles is required. In addition, no control element of the original FM-RDS receiver is used for other purposes or receives additional functions. This includes the advantage that an intuitive operation and user guidance is maintained and station buttons can be used as in normal operation.
Darüber hinaus behält die Lenkradfernbedienung im Auto ihre originären Funktionen. Daneben sind die Fernbedienungen in der Unterhaltungselektronik ebenfalls uneingeschränkt verwendbar. In addition, the steering wheel remote control keeps its original functions in the car. In addition, the remote controls in consumer electronics are also fully usable.
Des Weiteren erfordert die erfindungsgemäße Vorrichtung bzw. das erfindungsgemäße Verfahren keine Beschränkung auf eine feste Anzahl von Favoriten oder Speicherplätzen. Furthermore, the device according to the invention or the method according to the invention requires no restriction to a fixed number of favorites or memory locations.
Daneben ist eine dynamische Gestaltung der Senderliste möglich. Das heißt, die Senderauswahl durch Scrollen und Weiterblättern ist weiterhin möglich und erfordert kein träges bzw. für den Bediener lästiges Durchschalten von Sender zu Sender. Der Senderwechsel kann vielmehr ohne Zeitverlust in beliebiger Abfolge erfolgen. In addition, a dynamic design of the station list is possible. That is, the station selection by scrolling and scrolling is still possible and requires no lazy or annoying for the operator switching from station to station. The station change can rather take place without loss of time in any order.
Des Weiteren ist der Einbau eines zusätzlichen Bedien- oder Anzeigeelements nicht erforderlich und die einfache Installation und Integration des erfindungsgemäßen Verfahrens kann ohne besonderen Konfigurationsprozess erfolgen. Furthermore, the installation of an additional control or display element is not required and the simple installation and integration of the method according to the invention can be carried out without special configuration process.
Fig. 1 gibt die technische Realisierung / Konzept eines Nachrüst-DAB-Tuners mittels FM- RDS-Empfänger mit dem„Interactive RDS Broadcast"-Bedienkonzept wieder. Fig. 1 shows the technical realization / concept of a retrofit DAB tuner using FM RDS receiver with the "Interactive RDS Broadcast" media concept again.
Für die technische Realisierung des eigentlichen DAB-Tuners und den Frontends gibt es mehrere Möglichkeiten, wobei in keinem Fall der Einbau eines speziellen Chipsatzes erforderlich wird. Zur Durchführung des erfindungsgemäßen Verfahrens ist ein Doppeltuner zu verwenden, der mit Blick auf den Einsatz in Kraftfahrzeugen über die entsprechende automotive Tauglichkeit und eine ausreichende Empfangsempfindlichkeit verfügt.
Die erfindungsgemäßen Konzeptalternativen stellen grundsätzlich mindestens folgende Schnittstellen zur Verfügung: a) Digitaler Audio-Datenstrom [Stereo) For the technical realization of the actual DAB tuner and the front ends there are several possibilities, whereby in no case the installation of a special chipset is necessary. For carrying out the method according to the invention, a double tuner is to be used, which has the appropriate automotive suitability and sufficient reception sensitivity with a view to use in motor vehicles. The concept alternatives according to the invention basically provide at least the following interfaces: a) Digital audio data stream [stereo]
b) Datendienste b) Data services
c) Kommunikationsschnittstelle zum Steuern des DAB-Tuners und zum Auslesen der DAB-Senderliste c) Communication interface for controlling the DAB tuner and for reading the DAB station list
Da das komplette Bedienen des DAB-Tuners über den RDS-Kanal des FM-Tuners in der PAG-Headunit realisiert wird, müssen sinngemäß folgende Aufgaben in der Software implementiert werden: Since the complete operation of the DAB tuner is realized via the RDS channel of the FM tuner in the PAG head unit, the following tasks must be implemented in the software:
Die DAB-Senderliste muss zweckmäßigerweise nach Relevanz sortiert werden. Dazu wird jeder„Sender" statistisch erfasst. Je länger demnach ein Sender gehört wird, desto weiter vorne erscheint der Sender in der Senderliste. Dabei muss die Statistik auch bislang nicht empfangene Sender erfassen; letzteres ist z.B. für Pendler oder bei Urlaubsfahrten wichtig. The DAB station list must expediently be sorted by relevance. The longer a station is listened to, the further forward the station appears in the station list, and the statistics must also include stations not yet received, which is important, for example, for commuters or when traveling on holiday.
Das Sendermanagement legt anhand der DAB-Senderliste und der Statistik die ersten n Sender fest und weist jedem Sender eine Frequenz zu, welche vorzugsweise immer dieselbe sein soll. The transmitter management determines the first n transmitters on the basis of the DAB transmitter list and the statistics and allocates a frequency to each transmitter, which should preferably always be the same.
In einem anschließenden Schritt wird von jedem der ersten n Sender ein MPX-Signal ohne Audio gerechnet. Das RDS-Protokoll wird dabei so reduziert, dass nur der Sendername übertragen wird. Dadurch hat der RDS-Datenstrom eine feste Länge und Dauer (z.B. ca. 500 ms). Die MPX-Signale werden mit den festgelegten Frequenzen rechnerisch frequenzmoduliert, und im Speicher als „Samples" abgelegt. Als Hintergrundaktivität können mehr Samples in den Speicher gelegt werden als aktuell ausgegeben werden (Umschaltperformance). In a subsequent step, an MPX signal without audio is calculated by each of the first n transmitters. The RDS protocol is reduced so that only the station name is transmitted. As a result, the RDS data stream has a fixed length and duration (e.g., about 500 ms). The MPX signals are frequency-modulated at the specified frequencies and stored in memory as "samples." As background activity, more samples can be stored in memory than are currently output (switching performance).
Einige dieser Samples befinden sich ständig im Speicher und haben als„Sendername" die Bezeichnungen Some of these samples are always in memory and have the names as "sender name"
„— DAB—„ ,„— NEXT—„ ,„— FM—„ oder„—CONFIG—,, .
Die vom Sendermanagement festgelegten n Sender (Samples), werden rechnerisch addiert und ggf. als Summensignal wieder in dem Speicher hinterlegt. "- DAB", "- NEXT", "- FM" or "-CONFIG". The n transmitter defined by the sender management (Samples) are added by calculation and possibly stored as a sum signal in the memory again.
Unabhängig von den Samples errechnet ein Echtzeit-Prozess ein MPX-Signal mit den DAB- Audiodaten einschließlich des RDS-Signals. Dieses RDS-Signal soll Radiotext und ausgewählte Datendienste als TMC (Traffic Message Channel) Informationen beinhalten. Das so generierte Live-MPX-Signal wird ebenfalls mit der festgelegten Frequenz rechnerisch frequenzmoduliert und zu dem Summensignal der Samples aus dem Speicher in Echtzeit addiert. Regardless of the samples, a real-time process calculates an MPX signal with the DAB audio data including the RDS signal. This RDS signal is intended to include radio text and selected data services as TMC (Traffic Message Channel) information. The thus generated live MPX signal is also frequency modulated at the fixed frequency and added to the sum signal of the samples from the memory in real time.
Ein DAC (Digital Analog Converter) erzeugt aus diesem digitalen Datenstrom ein analoges Signal. Mit einem Mischer wird das Signal in den FM-Frequenzbereich transponiert, wobei auf folgendes hinzuweisen ist: A DAC (Digital Analog Converter) generates an analogue signal from this digital data stream. With a mixer, the signal is transposed into the FM frequency range, indicating the following:
Wird die Frequenz aus dem DAC über 10 MHz gehalten, liegen die Spiegelfrequenzen des Mischers systembedingt außerhalb des FM-Bandes. Mit einem Combiner wird das gerechnete FM-Signal mit dem empfangenen FM-Band gemischt und der PAG Headunit über den FM Eingang zugeführt. Um Abstrahlungen und Rückwirkungen auf die FM-Antenne zu vermeiden, wird u.U. ein Verstärker benötigt, der auch die Dämpfung des Combiners, dessen Funktion lediglich dazu benötigt wird, um im bisherigen FM-Betrieb das Sample„— DAB—„ dazu zu mischen, kompensieren kann. If the frequency from the DAC is kept above 10 MHz, the mirror frequencies of the mixer are due to the system outside the FM band. With a combiner, the calculated FM signal is mixed with the received FM band and fed to the PAG head unit via the FM input. To avoid radiation and repercussions on the FM antenna, u.U. requires an amplifier that can also compensate for the attenuation of the combiner whose function is only needed to mix the sample "- DAB-" in previous FM operation.
Im DAB-Betrieb ist die FM Antenne abgetrennt. In DAB mode, the FM antenna is disconnected.
Als Besonderheit der PAG-Headunit muss der FM-Tuner im FM-Betrieb die ZF im selben FM-Antennenkabel wieder an das Antenna Diversity (Antennendiversität) des Fahrzeugs zurückliefern. As a special feature of the PAG head unit, the FM tuner in FM mode must return the IF in the same FM antenna cable back to the antenna diversity (antenna diversity) of the vehicle.
Parallel dazu kann dieses ZF-Signal ausgewertet werden. Dazu werden die RDS- Informationen durch einen einfachen Tuner wieder zur Verfügung gestellt. Bei der Auswahl eines bestimmten„Senders" durch den Bediener im DAB-Betrieb aus seiner FM-Sendeliste entspricht diese RDS-Information exakt einer gesendeten RDS-Information. Dem DAB- Modul wird auf diesem Wege vermittelt, welchen Sender der Bediener jeweils hören will. In parallel, this IF signal can be evaluated. For this purpose, the RDS information is provided by a simple tuner again. When the operator selects a particular "sender" in his DAB mode from his FM transmission list, this RDS information corresponds exactly to a transmitted RDS information, in which way the DAB module is informed which transmitter the operator wants to hear in each case.
Das Sendermanagement stellt anschließend den DAB-Tuner auf diesen DAB-Sender ein und stellt das Audio-Signal und die Datendienste knackfrei dem Echtzeit-MPX-Coder zur
Verfügung. Bis zu diesem Zeitpunkt wurde bereits ein neues Summensignal aus den Samples im Speicher ohne den jetzt aktiven Sender gerechnet. The transmitter management then sets the DAB tuner to this DAB transmitter and provides the audio signal and the data services to the real-time MPX coder without cracking Available. Up to this point, a new sum signal has already been calculated from the samples in the memory without the currently active transmitter.
Der Bediener hört jetzt den ausgewählten Sender. - Wählt der Bediener zum Beispiel den Sender„— NEXT—„ aus, wechselt die Frequenz des aktiven Audio-Pfads auf die„NEXT"- Frequenz, damit die vom letzten Sender gehörte Audio weiter gehört werden kann. Es wird weiterhin aus den nächsten n Samples ein neues Summensignal gerechnet und verwendet. The operator now hears the selected station. For example, if the operator selects the station "- NEXT-", the frequency of the active audio path changes to the "NEXT" frequency so that the audio heard by the last station can still be heard Samples a new sum signal calculated and used.
Zweckmäßigerweise sollten Statistik, Sendermanagement und die Samples persistent verwaltet werden, damit beim Startup sofort die letzten Samples gesendet werden können. Conveniently, statistics, sender management and the samples should be managed persistently so that the last samples can be sent immediately at startup.
Die PLL (Phasenregelschleife) des oben erwähnten Tuners sollte vorzugsweise so dimensioniert werden, dass mittels der Software sowohl die ZF als auch das komplette FM- Band empfangen werden kann. The PLL (phase locked loop) of the tuner mentioned above should preferably be dimensioned so that both the IF and the complete FM band can be received by the software.
Vorzugsweise sollte auf der Hardwareseite die FM-Antenne als DAB-Antenne genutzt werden. Weiterhin vorzugsweise sollte die Antennendiversität des Fahrzeugs mithilfe eines 10,7 MHz Oszillators mit regelbarer Amplitude eingebunden werden. Preferably, on the hardware side, the FM antenna should be used as a DAB antenna. Further preferably, the antenna diversity of the vehicle should be integrated using a 10.7 MHz variable amplitude oscillator.
Vorzugsweise sollte eine Möglichkeit vorgesehen werden, den DAB-Tuner auch ohne ZF- Auswertung betreiben zu können. Dazu kann eine leise Kennung im Audioband mit eingesampelt werden, welche beim Umschalten an den Endstufenausgängen bestimmt wird. Preferably, a possibility should be provided to operate the DAB tuner without ZF evaluation can. For this purpose, a quiet identifier in the audio band can be sampled, which is determined when switching over to the power amplifier outputs.

Technische Beschreibung technical description
Das DAB Modul für den Nachrüstmarkt besteht im Wesentlichen aus einem DAB Empfänger, einem leistungsstarken Digitalen Signal Prozessor [DSP], einem FM Tuner für die von der Headunit kommende Zwischenfrequenz (ZF) und einem Netzteil nach dem Automotive Standard. The DAB module for the aftermarket consists essentially of a DAB receiver, a powerful Digital Signal Processor [DSP], an FM tuner for the head unit coming intermediate frequency (IF) and an AC adapter according to the Automotive Standard.
Der Einsatz einer zusätzlichen Hardware ist nicht erforderlich, da die Bedienung des Empfängers durch bestehende Bedieneinheiten - wie z.B. dem Bedienteil der Headunit - erfolgt.
Die am Antenneneingang vieler Headunits zur Verfügung stehende ZF-Information wird als Rückinformationskanal verwendet. Alternativ kann eine Kennung am Audiosignal als Rückkanal verwendet werden, wodurch die erfindungsgemäße„Interactive RDS Broadcast"- Kommunikation ebenfalls realisiert werden kann. The use of additional hardware is not required because the operation of the receiver by existing control units - such as the control unit of the head unit - takes place. The IF information available at the antenna input of many head units is used as feedback information channel. Alternatively, an identifier on the audio signal can be used as the return channel, as a result of which the "interactive RDS broadcast" communication according to the invention can likewise be realized.
Um auf DAB umzuschalten, muss sich die Headunit im FM-Modus befinden. Das DAB-Modul mischt zum FM-Antennensignal auf einer freien Frequenz ein FM-Signal ohne Audio mit der RDS-Information z.B. „— DAB— ". Dieser Sender erscheint in der FM-Senderliste der Headunit an erster Stelle, da dieser im Vergleich zu dem über die Antenne empfangenen FM-Sender eine höhere Sendeleistung hat - oder ein Sonderzeichen am Anfang im Falle einer alphabetischen Reihenfolge aufweist. Der ausgewählte Sender ist als RDS-Information in der von der Headunit am Antenneneingang bereitgestellten ZF enthalten und steht über einen ZF-Filter und den Tuner dem DSP zu Verfügung. To switch to DAB, the head unit must be in FM mode. The DAB module mixes to the FM antenna signal at a free frequency an FM signal without audio with the RDS information e.g. "- DAB-." This station appears first in the FM station list of the head unit because it has a higher transmission power compared to the FM station received through the antenna - or has a special character at the beginning in the case of alphabetical order. The selected transmitter is included as RDS information in the IF provided by the head unit at the antenna input and is available to the DSP via an IF filter and the tuner.
Nachdem die Rückinformation des ausgewählten Senders beim DSP angekommen ist, schaltet das Modul in den DAB-Modus um. In dieser Situation wird die FM-Antenne weggeschaltet und n Sender aus der DAB-Senderliste ohne Audio mit definierter Frequenz und DAB-Information (Sendername vom DAB-Tuner) an die Headunit gesendet. Über die ZF bekommt der DSP wieder die Rückmeldung, welcher Sender ausgewählt wird und aktiviert das Audiosignal für diesen Sender. Dem Bediener wird dabei der Eindruck vermittelt, dass sich die Headunit im DAB-Modus genauso verhält, wie sie sich vorher im FM-Modus verhalten hat. After the return information of the selected transmitter has arrived at the DSP, the module switches to the DAB mode. In this situation, the FM antenna is switched off and n stations are sent from the DAB station list without audio with a defined frequency and DAB information (station name from the DAB tuner) to the head unit. The DSP gets the feedback on which transmitter is selected via the IF and activates the audio signal for this transmitter. The operator is given the impression that the head unit in DAB mode behaves exactly as it had previously behaved in FM mode.
Fig. 3 zeigt„-DAB— " als Sender in der FM-Senderliste gemäß eines Bedienkonzepts. Der Bediener findet in der FM-Senderliste einen weiteren Sender mit der Bezeichnung—DAB--. Bei Auswahl dieses Senders wird in den DAB-Modus umgeschaltet. Fig. 3 shows "-DAB-" as a station in the FM station list according to a control concept, and the operator finds another station in the FM station list-DAB--, which switches to DAB mode when this station is selected ,
Es baut sich eine neue Senderliste mit den ersten n (z.B. n=10) Sendern auf, die über DAB empfangen werden. An erster Stelle der neuen Senderliste erscheint jetzt -FM-, um wieder in den FM-Modus zurückzuschalten zu können. An zweiter Stelle erscheint die Information „-NEXT— ,„ um die nächsten n Sender anzuzeigen. Die Sender, die in der Senderliste angeboten werden, können in einer bevorzugten Ausführungsform - wie in dem FM-Betrieb - auf Stationstasten weiterhin gespeichert werden.
Der Einsatz des Bedienkonzepts ist vielfältig. Anstelle des DAB- Empfängers kann jedes beliebige analoge wie digitale Audiomodul (wie z.B. SDARS [Satellite Digital Audio Radio Services) Tuner, MP3 Player etc.) eingesetzt werden. A new station list is built up with the first n (eg n = 10) stations that are received via DAB. In the first place of the new channel list appears -FM- to be able to switch back to the FM mode. In the second place appears the information "-NEXT-" to display the next n channels. The transmitters that are offered in the station list can, in a preferred embodiment, continue to be stored on station buttons as in FM mode. The use of the operating concept is manifold. Any analog or digital audio module (such as SDARS tuner, MP3 player, etc.) can be used instead of the DAB receiver.
