Abstract
Description
Die
vorliegende Erfindung betrifft eine Kommunikationsvorrichtung zur Übertragung
von Kommunikationsdaten innerhalb eines Fahrzeugs umfassend eine
Empfangseinrichtung zum Empfangen eines Eingangssignals (
Eine derartige Kommunikationsvorrichtung kann beispielsweise eine Kfz-Freisprechanlage sein. Kfz-Freisprechanlagen nach dem Stand der Technik dienen zur Übertragung von Daten von einem Mobiltelefon an eine Audiowiedergabeeinrichtung, meistens an ein Autoradio. Wird beispielsweise ein Fahrer während einer Autofahrt über sein Mobiltelefon angerufen, so erleichtert eine Kfz-Freisprechanlage die Entgegennahme des Anrufes erheblich. Der Fahrer drückt nur kurz auf eine Eingabevorrichtung an dem Mobiltelefon zur Abnahme des Anrufes. Über die Kfz-Freisprechanlage, welche die Sprechsignale zur Wiedergabe an das Radio weiterleitet, kann der Fahrer die Stimme des Anrufers vernehmen, ohne dass er das Mobiltelefon an den Kopf halten muss.A Such communication device may, for example, a car-handsfree system be. Automotive hands-free systems according to the prior art are used for transmission data from a mobile phone to an audio player, mostly to a car radio. For example, a driver during a Drive over Called his cellphone, so facilitates a car handsfree the receipt of the call considerably. The driver only presses briefly on an input device on the mobile phone for acceptance of the call. about the car handsfree, which the speech signals for playback to the radio, the driver can hear the voice of the caller without having to hold the mobile phone to his head.
Der Fahrer muss keine Umstellungen am Autoradio vornehmen, um die Stimme des Anrufers über das Autoradio ungestört von Musik hören zu können, da über eine Mutesignalisierung (Stummschaltung) von der Kfz-Freisprechanlage dem Radio mitgeteilt werden kann, ob ein Telefongespräch vorliegt oder nicht. Dies erspart dem Fahrer ein zusätzliches Ein- und Ausschalten der Musik des Autoradios, wann immer er einen Anruf entgegen nehmen oder beenden will.Of the Driver does not have to make any changes to the car radio to get the vote of the caller the car radio undisturbed to listen to music to be able to over there a Mutesignalisierung (mute) of the car handsfree system the radio can be informed if there is a telephone conversation or not. This saves the driver an additional on and off the music of the car radio whenever he takes a call or wants to quit.
Moderne Mobiltelefone besitzen immer häufiger auch einen integrierten Mediaplayer für komprimierte Musikdateien, z.B. einen MP3-Player, mit Speicherkarte. Über diese Zusatzausrüstung kann der Benutzer ein beliebiges Musikstück zum Abspielen auswählen. Allerdings eignen sich Kfz-Freisprechanlage nach dem Stand der Technik schlecht zum Übertragen von Musikstücken, da herkömmliche Kfz-Freisprechanlagen MP3-Dateien nicht mit Stereoqualität wiedergeben können.modern Mobile phones are becoming more common also an integrated media player for compressed music files, e.g. an MP3 player, with memory card. About this additional equipment can the User any song to play. However, automotive hands-free system according to the prior art are suitable bad to transfer of music, as conventional car handsfree Can not play MP3 files with stereo quality.
Die Aufgabe der vorliegenden Erfindung besteht darin, eine Kommunikationsvorrichtungen zu entwickeln, mit der auch Musikstücke von einem Mobiltelefon auf ein Autoradio so übertragen werden können, dass sich für das Ohr des Zuhörers ein gefälliger Stereo-Sound ergibt.The Object of the present invention is a communication devices to develop, with which also pieces of music from a mobile phone so transferred to a car radio can be that for himself the ear of the listener a pleasing one Stereo sound results.
Erfindungsgemäß wird diese Aufgabe durch eine Kommunikationsvorrichtung nach Anspruch 1 und ein Verfahren nach Anspruch 7 gelöst. Vorteilhafte Weiterbildungen der erfindungsgemäßen Kommunikationsvorrichtung sind in den Unteransprüchen definiert.According to the invention this Task by a communication device according to claim 1 and a method according to claim 7 solved. Advantageous developments the communication device according to the invention are defined in the subclaims.
Die vorliegende Erfindung wird nun anhand der beigefügten Zeichnung näher erläutert, die ein Prinzipschaltbild einer erfindungsgemäßen Audioanlage für ein Kraftfahrzeug zeigt.The The present invention will now be explained in more detail with reference to the accompanying drawing which a schematic diagram of an audio system according to the invention for a motor vehicle shows.
Das nachfolgend näher geschilderte Ausführungsbeispiel stellt lediglich eine bevorzugte Ausführungsform der vorliegenden Erfindung dar.The below described embodiment merely represents a preferred embodiment of the present invention Invention.
