“Unità elettronica DAB-FM per la conversione di dati audio in radiodiffusione digitale DAB in dati audio in radiodiffusione FM (Frequency Modulation) stereo che permette l’ascolto di emittenti in DAB da parte di autoradio (OEM o aftermarket) FM (Frequency Modulation) stereo, pilotabile attraverso comandi al volante”. "DAB-FM electronic unit for converting audio data in DAB digital broadcasting into audio data in FM (Frequency Modulation) stereo broadcasting that allows car radios (OEM or aftermarket) FM (Frequency Modulation) to listen to DAB broadcasters stereo, controllable via steering wheel controls ”.
La presente invenzione riguarda un’unità elettronica denominata “DAB-FM” volta alla acquisizione di dati audio in radiodiffusione digitale DAB e loro riconversione in dati audio in radiodiffusione FM (Frequency Modulation) stereo che contiene un dispositivo che la rende pilotabile attraverso i comandi a volante del veicolo (se presenti). The present invention relates to an electronic unit called "DAB-FM" aimed at the acquisition of audio data in DAB digital broadcasting and their reconversion into audio data in FM (Frequency Modulation) stereo broadcasting that contains a device that makes it manageable through the commands to vehicle steering wheel (if any).
Più dettagliatamente, l’invenzione concerne un’unità elettronica capace di effettuare una conversione del segnale in radiodiffusione digitale DAB (Digital Audio Broadcasting, che consente la multiplazione del segnale, ovvero la possibilità di far condividere a più segnali lo stesso canale e di conseguenza più utenti in grado di condividere lo stesso mezzo trasmissivo senza interferenza tra di essi), rendendolo compatibile con lo standard FM stereo (Frequency Modulation, che consiste nel modulare la frequenza del segnale radio che si intende utilizzare per la trasmissione in maniera proporzionale all'ampiezza del segnale che si intende trasmettere), ricevuto da qualsiasi autoradio e che può essere gestita tramite l’utilizzo di comandi al volante OEM o aftermarket qualora presenti sul veicolo. More specifically, the invention relates to an electronic unit capable of converting the signal into DAB (Digital Audio Broadcasting) digital broadcasting, which allows signal multiplexing, i.e. the possibility of making multiple signals share the same channel and consequently more users able to share the same transmission medium without interference between them), making it compatible with the FM stereo standard (Frequency Modulation, which consists in modulating the frequency of the radio signal to be used for transmission in a manner proportional to the amplitude of the signal to be transmitted), received by any car radio and which can be managed through the use of OEM or aftermarket steering wheel controls if present on the vehicle.
Nel seguito, la descrizione sarà rivolta all’applicazione ad un’autoradio, ma è ben evidente come la stessa non debba essere considerata limitata a questo impiego specifico, in quanto laddove esista la possibilità di captare la programmazione di emittenti radiofoniche si potrà comunque giovarsi dei vantaggi della presente invenzione, realizzando ugualmente le di essa peculiari intenzioni descritte nel presente brevetto d’invenzione. In the following, the description will be addressed to the application to a car radio, but it is very clear that it should not be considered limited to this specific use, since where there is the possibility of capturing the programming of radio stations, it is still possible to benefit from the advantages of the present invention, also realizing its particular intentions described in the present invention patent.
Al presente stato di cose, l’utente non ha facoltà di interagire, tramite i comandi al volante del veicolo, con emittenti DAB (Digital Audio Broadcasting), in quanto non esistono sistemi capaci di convertire il suddetto segnale DAB (Digital Audio Broadcasting) in segnale FM (Frequency Modulation) stereo attraverso le tradizionali autoradio che operano sullo standard FM (Frequency Modulation) stereo. At the present state of things, the user is not entitled to interact, via the steering wheel controls of the vehicle, with DAB (Digital Audio Broadcasting) broadcasters, as there are no systems capable of converting the aforementioned DAB (Digital Audio Broadcasting) signal into FM (Frequency Modulation) stereo signal through traditional car radios operating on the FM (Frequency Modulation) stereo standard.
Alla luce di quanto sopra, lo scopo della presente invenzione è quello di fornire un’interfaccia in grado di acquisire, elaborare, codificare dati audio in radiodiffusione digitale (DAB) in modo che possano essere riconvertiti in dati audio FM (Frequency Modulation) stereo standard modulati attraverso un’interfaccia gestita tramite comandi al volante. In light of the above, the object of the present invention is to provide an interface capable of acquiring, processing, encoding audio data in digital broadcasting (DAB) so that it can be converted back into standard stereo FM (Frequency Modulation) audio data. modulated through an interface managed via steering wheel controls.
Forma pertanto oggetto specifico della presente invenzione una unità (1) “DAB-FM”; e un mezzo di controllo interno all’unità che operi con i comandi al volante, se presenti nel veicolo, (2). Therefore, the specific object of the present invention is a unit (1) "DAB-FM"; and a means of control inside the unit that operates with the steering wheel controls, if present in the vehicle, (2).
L’unità in oggetto del presente brevetto può essere anche gestita tramite remote control da radiocomando (3). The unit in question of this patent can also be managed via remote control by radio control (3).
3⁄43⁄4inoO≤ Preferibilmente secondo l’invenzione, l’apparato di riproduzione dei dati audio è l’impianto audio normalmente utilizzato negli autoveicoli, cioè quello in FM (Frequency Modulation) stereo. 3⁄43⁄4inoO≤ Preferably according to the invention, the audio data reproduction apparatus is the audio system normally used in motor vehicles, ie the one in FM (Frequency Modulation) stereo.
