SmartKassette für den Einsatz als digitaleSmart cassette for use as digital
Musikkassette bei herkömmlichen KassettenrekordernMusic cassette in conventional cassette recorders
Aus der älteren deutschen Patentanmeldung P 39 03 454 AI ist ein in EDV-Einrichtungen einsteckbares Element (SmartKassette) bekannt, das als Kassette ausgebildet und mit einer besonderen Schnittstelle ausgerüstet ist. Diese Schnittstelle ist derart ausgebildet, daß eine Datenübertragung zwischen einem in der Kassette befindlichen Prozessor und der EDV-Einrichtung über die in der EDV-Einrichtung ohnehin vorhandenen Schreib-/Lese- einrichtung durchführbar ist. Der besondere, mit diesen Merk¬ malen verbundene Vorteil besteht darin, daß ein Datenaustausch zwischen dem Prozessor der Kassette und der EDV-Einrichtung möglich ist, ohne daß zusätzliche Schnittstellen erforderlich sind. Ferner ist das Element mit einem Stromgenerator ausge¬ rüstet, der, unabhängig von einer externen Steckverbindung den Prozessor und andere Komponenten des Elements mit dem not¬ wendigen Strom versorgt. Die Gestaltung des Stromgenerators ist aus der deutschen Patentanmeldung P 41 22 170.2 bekannt.From the older German patent application P 39 03 454 AI an insertable element in EDP devices (SmartKassette) is known, which is designed as a cassette and equipped with a special interface. This interface is designed in such a way that data can be transmitted between a processor located in the cassette and the EDP device via the read / write device which is present in the EDP device. The particular advantage associated with these features is that data can be exchanged between the processor of the cassette and the EDP device without the need for additional interfaces. Furthermore, the element is equipped with a current generator which, independently of an external plug connection, supplies the processor and other components of the element with the necessary current. The design of the current generator is known from German patent application P 41 22 170.2.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, diese Technologie nicht nur für den Austausch von Daten zwischen einer SmartKassette und einer EDV-Einrichtung zu benutzen, sondern für die Einsatz als digitale "Magnetband"-Kassette in Verbindung mit herkömmlichen Kassettenrekordern zu benutzen. Diese Aufgabe wird dadurch gelöst, daß die SmartKassette mit einer Magnetschnittstelle in der Ausprägung als Digital/Analόg- andler zum Abspielen von Musik über einen herkömmlichen, analogen Kassettenrekorder, einem Analog/Digital- andler zum Bespielen von Musik über einen herkömmlichen, analogen Kassettenrekorder, einer digitalen Schnittstelle zum Bespielen der SmartKassette in digitaler Form, einem Sensor in der Nähe des 'Magnetkopfs, damit die SmartDiskette feststellen kann, ob Musik abgespielt/bespielt werden soll oder ob schnell vorwärts /rückwärts gespult werden soll, einer Steckverbindung zur Stromversorgung der elektronischen Komponenten der Smart¬ Kassette während dem Bespielen mit digitalisierter Musik und zum gleichzeitigen Aufladen der wahlweise vorhandenen Batterie sowie mit einem Prozessor und digitalem Speicher in ent¬ sprechender Technologie zur Speicherung der digitalisierten Musik ausgerüstet wird.The present invention has for its object to use this technology not only for the exchange of data between a smart cassette and an EDP device, but for use as a digital "magnetic tape" cassette in connection with conventional cassette recorders. This object is achieved in that the SmartKassette with a magnetic interface in the form of a digital / analogue changer for playing music via a conventional analog cassette recorder, an analogue / digital changer for recording music via a conventional analog cassette recorder, one digital interface for recording the SmartCassette in digital form, a sensor near the 'magnetic head, so that the SmartDiskette can determine whether music should be played / played or whether fast forward / backward should be rewound, a plug connection for the power supply of the electronic components of the Smart¬ cassette while recording with digitized music and for simultaneous charging of the optionally available battery and a processor and digital memory in appropriate technology for storing the digitized music.
Die zur Zeit vorhandenen Träger für digitalisierte Musik wie Compact Disc (CD), Mini Disc (MD), Digital Audio Tape (DAT) oder Digital Compact Cassette (DCC) haben alle einen gemein¬ samen Nachteil: zum Abspielen werden entsprechende Geräte benötigt. Es ist nicht möglich, mit herkömmlichen Abspielge¬ räten die Vorteile der digital aufgezeichneten Musik auszu¬ nutzen. Ein weiterer Nachteil ist, daß die zur Zeit vorhan¬ denen digitalen Tonträger und Abspielgeräte bei Erschütte¬ rungen und großer Hitzeeinwirkung störanfällig sind.The currently available carriers for digitized music such as compact disc (CD), mini disc (MD), digital audio tape (DAT) or digital compact cassette (DCC) all have a common disadvantage: appropriate devices are required for playing them. It is not possible to utilize the advantages of digitally recorded music with conventional playback devices. A further disadvantage is that the currently available digital sound carriers and players are susceptible to failure in the event of vibrations and high heat.
Mit dieser Erfindung werden die genannten Nachteile gänzlich beseitigt. Als Schnittstelle zu herkömmlichen Kassetten¬ rekordern dient der Digital/Anlaog-Wandler über den die digital aufgezeichneten Musikstücke ohne Inhaltsverlust über¬ tragen werden. Mit herkömmlichen Kassettenrekordern kann auch Musik auf die SmartKassette aufgezeichnet werden, in diesem Fall jedoch nur mit geringfügig besserer Qualität als auf herkömmlichen Magnetbandkassetten.With this invention, the disadvantages mentioned are completely eliminated. The digital / analog converter, via which the digitally recorded pieces of music are transmitted without loss of content, serves as an interface to conventional cassette recorders. With conventional tape recorders, too Music can be recorded on the SmartCassette, but in this case only with a slightly better quality than on conventional magnetic tape cassettes.
Vorteile, Einzelheiten und Anwendungsmöglichkeiten dieser Erfindung sollen anhand den in den Figuren 1 und 2 schematisch dargestellten Ausführungsbeispielen erläutert werden.Advantages, details and possible uses of this invention will be explained with reference to the exemplary embodiments shown schematically in FIGS. 1 and 2.

Die Stromschnittstelle 15 wird dabei mit der Stromversorgung 16 des Geräts 13 verbunden. Die digitale Schnittstelle 14 wird mit dem Prozessor 17 des Geräts 13 verbunden, der seinerseits mit anderen, nicht darge¬ stellten Komponenten des Gerätes 13 verbunden ist.the interface to the SmartCassette 1 in a device 13, which is used to record the SmartCassette 1 with digitized music via the digital interface 14 and to supply the SmartCassette 1 with power during the recording via the current interface 15. The current interface 15 is connected to the power supply 16 of the device 13. The digital interface 14 is connected to the processor 17 of the device 13, which in turn is connected to other components of the device 13, not shown.
Im folgenden wird der Verarbeitungsablauf beim Bespielen und Abspielen von digitalisierter Musik mit der SmartKassette beschrieben.The processing sequence for recording and playing digitized music with the SmartCassette is described below.
Bespielen der SmartKassette mit digitalisierter Musik über ein spezielles GerätRecording of the SmartCassette with digitized music via a special device
Die in dem Gerät 13 vorhandene digitalisierte Musik wird im Prozessor 17 des Geräts 13 nach bekannten Verfahren wie z.B. MPEG oder ATRAC komprimiert und über die digitale Schnitt¬ stelle 14/11 in der Prozessor 4 der SmartKassette geladen. Es ist jedoch auch möglich die digitalisierte Musik im Prozessor 4 der SmartKassette 1 nach den bekannten Verfahren zu kompri¬ mieren. Im Prozessor 4 der SmartKassette 1 wird ein Datei¬ system verwaltet und die digitalisierten Informationen werden in die Speicherelemente 5 abgespeichert. Da zum Abspeichern der Informationen mehr Strom genötigt wird, als von dem Strom¬ generator 6 , 1 generiert werden kann, werden die elektro¬ nischen Bauteile der SmartKassette 1 während diesem Vorgang mit zusätzlichem Strom von dem Gerät 13 über die Stromschnitt¬ stelle 15/9 versorgt. Abspielen von digitalisierter Musik über einen herkömmlichen KassettenrekorderThe digitized music present in the device 13 is compressed in the processor 17 of the device 13 according to known methods such as MPEG or ATRAC and loaded into the processor 4 of the smart cassette via the digital interface 14/11. However, it is also possible to compress the digitized music in the processor 4 of the smart cassette 1 according to the known methods. A file system is managed in the processor 4 of the smart cassette 1 and the digitized information is stored in the memory elements 5. Since more current is required to store the information than can be generated by the current generator 6, 1, the electronic components of the smart cassette 1 are supplied with additional current from the device 13 via the current interface 15/9 during this process provided. Play digitized music on a conventional tape recorder
Zum Abspielen von digitalisierter Musik über einen herkömm¬ lichen Kassettenrekorder wird die SmartKassette 1 in das Lauf¬ werk des Kassettenrekorders gesteckt. Wenn sich der Antrieb 6 bewegt, wird über den Stromgenerator 6, 7 Strom erzeugt und der Prozessor 4 über den Stromregulator 8 gespeist. Je nachdem welcher Stromgenerator den Strom liefert, weiß der Prozessor 4 ob die Musikstücke vorwärts oder rückwärts ausgewählt werden sollen. Wenn ferner der Sensor 12 an den Prozessor 4 meldet, daß der Schreib-/Lesekopf des Kassettenrekorders sich gesenkt hat weiß der Prozessor 4, daß Musik abgespielt werden soll. Dazu wird aufgrund des Dateisystems auf die Speicherbausteine 5 zugegriffen und das entsprechende Musikstück ausgewählt. Die von den Speicherbausteinen 5 empfangenen Informationen werden im Prozessor 4 nach den bekannten Komprimierungsverfahren entkomprimiert und an den Digital/Analogwandler 3 weiterge¬ leitet. Im Digital/Analogwandler 3 werden die Signale umge¬ wandelt, verstärkt und an die Magnetschnittstelle 2 als ana¬ loge Signale weitergeleitet. Der Schreib-/Lesekopf eines her¬ kömmlichen Kassettenrekorders empfängt die Signale als ob sie von einem Magnetband stammen würden, jedoch nicht in der für Magnetbänder üblichen Qualität sondern in der bei digitalen Tonträgern üblichen Qualität.To play digitized music via a conventional cassette recorder, the smart cassette 1 is inserted into the drive of the cassette recorder. When the drive 6 moves, current is generated via the current generator 6, 7 and the processor 4 is fed via the current regulator 8. Depending on which power generator supplies the power, the processor 4 knows whether the music pieces should be selected forwards or backwards. Furthermore, if the sensor 12 reports to the processor 4 that the read / write head of the cassette recorder has lowered, the processor 4 knows that music should be played. For this purpose, the memory modules 5 are accessed on the basis of the file system and the corresponding piece of music is selected. The information received by the memory modules 5 is decompressed in the processor 4 according to the known compression methods and passed on to the digital / analog converter 3. In the digital / analog converter 3, the signals are converted, amplified and passed on to the magnetic interface 2 as analog signals. The read / write head of a conventional cassette recorder receives the signals as if they came from a magnetic tape, but not in the quality customary for magnetic tapes, but in the quality customary for digital sound carriers.
Wird bei einem herkömmlichen Kassettenrekorder die Taste "schneller Vorlauf" oder "schneller Rücklauf" gedrückt, stellt der Prozessor 4 der SmartKassette 1 dies dadurch fest, daß entweder der rechte Stromgenerator 6, 7, oder der linke Strom¬ generator 6, 7 den Strom liefert und ferner, daß der Sensor 12 nicht das Absenken des Schreib-/Lesekopfs des Kassetten¬ rekorders meldet. In diesem Fall wählt der Prozessor über das Dateisystem, abhängig welcher Stromgenerator 6,7 den Strom liefert das nächste oder das vorherige Musikstück aus. Bespielen von Musik über einen herkömmlichen KassettenrekorderIf the "fast forward" or "fast rewind" key is pressed in a conventional cassette recorder, the processor 4 of the smart cassette 1 detects this in that either the right-hand current generator 6, 7 or the left-hand current generator 6, 7 supplies the current and further that the sensor 12 does not report the lowering of the read / write head of the cassette recorder. In this case, the processor uses the file system to select the next or the previous piece of music, depending on which power generator 6,7 supplies the power. Record music on a conventional tape recorder
Zum Bespielen von Musik über einen herkömmlichen Kassetten¬ rekorder wird die SmartKassette 1 in das Laufwerk des Kassettenrekorders gesteckt. Wenn sich der Antrieb 6 bewegt, wird über den Stromgenerator 6, 7 Strom erzeugt und der Prozessor 4 über den Stromregulator 8 gespeist. Wenn ferner der Sensor 12 an den Prozessor 4 meldet, daß der Schreib-/ Lesekopf des Kassettenrekorders sich gesenkt hat weiß der Prozessor 4, daß Musik abgespielt oder bespielt werden soll. Wenn der Prozessor 4 über die Magnetschnittstelle 2 und den Analog-/Digital-Wandler Signale erhält, weiß er, daß Musik eingespielt werden soll. In diesem Fall werden die empfangenen Signale nach einem herkömmlichen Komprimierungsverfahren komprimiert und über ein Dateisystem werden die digitali¬ sierten Informationen in die Speicherelemente 5 abgespeichert. Beim Abspielen von Musikstücken, die auf diese Weise aufge¬ zeichnet wurden, ist die Qualität jedoch nur geringfügig besser als die auf herkömmlichen Magnetbändern aufgezeichneten Stücke.To record music via a conventional cassette recorder, the smart cassette 1 is inserted into the drive of the cassette recorder. When the drive 6 moves, current is generated via the current generator 6, 7 and the processor 4 is fed via the current regulator 8. Furthermore, if the sensor 12 reports to the processor 4 that the read / write head of the cassette recorder has lowered, the processor 4 knows that music should be played or recorded. When the processor 4 receives signals via the magnetic interface 2 and the analog / digital converter, it knows that music should be played. In this case, the received signals are compressed using a conventional compression method and the digitized information is stored in the memory elements 5 via a file system. When playing music pieces that have been recorded in this way, however, the quality is only slightly better than that recorded on conventional magnetic tapes.
Aus der folgenden Auflistung geht die Vielzahl der Anwendungs¬ möglichkeiten einer nach der Erfindung gestalteten SmartKassette mit den damit verbundenen Vorteilen hervor: Anwendungsmöglichkeiten/Vorteile:The following list shows the multitude of possible uses of a smart cassette designed according to the invention, with the associated advantages: Possible uses / advantages:
- Die Besitzer von herkömmlichen Kassettenabspielgräten erhalten die Musikqualität, die sonst nur mit digitalen Abspielgeräten möglich ist.- The owners of conventional cassette players get the music quality that is otherwise only possible with digital players.
- Das wirkt sich besonders vorteilhaft bei in Autoradios eingebauten Kassettenabspielgeräten aus, da die SmartKassette gegen Hitze und Erschütterungen unempfindlich ist.- This is particularly advantageous for cassette players installed in car radios, since the SmartCassette is insensitive to heat and vibrations.
- Mit der SmartKassette können Musikstücke auch über herkömmliche Kassettenrekorder mit besserer Qualität als bisher aufgezeichnet werden.- With the SmartCassette, music can also be recorded with conventional cassette recorders with better quality than before.
- Wenn man kein eigenes Gerät zum Aufspielen digitalisierter Musik besitzt, kann man z.B. in ein Geschäft gehen, sich bestimmte Titel auswählen und diese dann mit sehr hoher Geschwindigkeit (wenige Sekunden) auf eine SmartKassette aufspielen lassen.- If you don't have your own device for playing digitized music, you can e.g. go to a store, select certain titles and then have them loaded onto a SmartCassette at very high speed (a few seconds).
- Abhängig von den eingesetzten Speicherbausteinen können Musikstücke mit einer Laufzeit von mehreren Stunden aufgespielt werden. - Depending on the memory modules used, pieces of music with a running time of several hours can be played.
