Abstract

Digital audio data can be adapted and converted into analog audio data for playback on a commercial cassette recorder by using a semiconductor memory device and an electronics unit to enable the digital audio data files to be read from the main store and to be transmitted as an analog signal to the audio head of the replay device, for the conversion of the digital audio data into analog data. The M-tape-3 is inserted as an analog audio compact-cassette into the playback device drive.

Description

Die Erfindung ermöglicht es, Audiodaten, die auf digitalen Halbleiterspeichern abgelegt wurden, mit Hilfe eines handelsüblichen Cassetten-Abspielgerätes wiederzugeben.The invention enables audio data stored on digital semiconductor memories were reproduced with the help of a commercially available cassette player.

Musikdateien, wie sie häufig über das Internet übertragen werden, sind weder in ihrem Datenformat (z. B. MP1-Level3), noch in dafür sinnvollen Speichermedien (z. B. sog. Flashsticks oder MMC-Cards) abspielbar in Geräten wie Stereo-Cassetten-Recordern oder Walkmans, welche beide unter Konsumenten eine hohe Verbreitung finden.Music files, as they are often transmitted over the Internet, are neither in their Data format (e.g. MP1-Level3), still in meaningful storage media (e.g. so-called Flashsticks or MMC cards) can be played in devices such as stereo cassette recorders or Walkmans, both of which are very popular among consumers.

Um die Möglichkeit zu bieten, diese Dateien auf bereits vorhandenen Cassetten- Abspielgeräten wiederzugeben, ohne diese dafür umzubauen oder umzuprogrammieren, benötigt man ein Gerät, welches die äußere Form einer sog. Compact Cassette hat, aber kein Magnetband enthält, sondern einen Halbleiterspeicher und eine Elektronik, die es erlaubt, digitale Audiodateien vom Halbleiterspeicher zu lesen und diese als analoges Signal an den Tonkopf des Wiedergabegerätes zu übertragen. Diese Vorrichtung wird wie eine analoge Audio Compact Cassette in das Laufwerk des Abspielgerätes eingeführt, und vom Laufwerk auch als Audio Compact Cassette erkannt. Dadurch können die digital gespeicherten Daten mit Hilfe von analogen Geräten wie Walkmans, Radiorecordern oder HIFI-Anlagen in hoher Qualität und ggf. auch in Stereo wiedergegeben werden.In order to offer the possibility of storing these files on existing cassette Play playback devices without converting or reprogramming them, you need a device that has the outer shape of a so-called compact cassette, but not one Contains magnetic tape but a semiconductor memory and electronics that allows read digital audio files from the semiconductor memory and send them as an analog signal to the Transfer head of the playback device. This device is like an analog Audio Compact Cassette inserted into the drive of the playback device and from the drive also recognized as an audio compact cassette. This allows the digitally stored data with the help of analog devices such as Walkmans, radio recorders or HIFI systems in high Quality and possibly also in stereo.

Die Bedienung wie der bei Compact Cassetten üblichen Funktionen "WIEDERGABE"; "SCHNELLER VORLAUF"; "SCHNELLER RÜCKLAUF" etc. kann entweder über eine Funk- oder Kabelfernbedienung mit entsprechenden Tasten erfolgen und/oder durch Erfassen und Auswerten der Geschwindigkeit und der Drehrichtung der Capstan-Welle und der Wickelteller des Cassetten-Abspielgerätes.Operation is the same as for the "PLAYBACK" functions that are common with compact cassettes; "FAST FORWARD"; "FAST RETURN" etc. can either be over a radio or cable remote control with appropriate buttons and / or by Acquisition and evaluation of the speed and direction of rotation of the capstan shaft and the Winding plate of the cassette player.

Die Erfindung enthält, eingebaut in ein Gehäuse, welches dem einer Compact Cassette entspricht, die folgenden Module:
The invention contains the following modules, installed in a housing which corresponds to that of a compact cassette:

  • - Einen Halbleiterspeicher, austauschbar oder fest eingebaut und wiederbeschreibbar.- A semiconductor memory, replaceable or permanently installed and rewritable.

  • - Eine Anpassung der analogen Signale an die elektromagnetische Übertragungseinheit.- An adaptation of the analog signals to the electromagnetic transmission unit.
  • - Eine Übertragungseinheit, welche die aufbereiteten Analogsignale auf elektromagnetischem Wege an den Tonkopf sendet.- A transmission unit, which the processed analog signals sends electromagnetic way to the head.
  • - Wahlweise eine Empfangseinheit bzw. Auswerteelektronik für eine optimale Funk- oder Kabelfernbedienung.- Optionally a receiving unit or evaluation electronics for optimal radio or Cable remote control.
  • - Eine Sensorik zur Auswertung der Drehrichtung und der Geschwindigkeit der Wickelteller und der Capstan-Welle.- A sensor system for evaluating the direction of rotation and the speed of the winding plate and the capstan wave.
  • - Eine Energieversorgung für die o.g. Module.- An energy supply for the above Modules.

Die o.g. elektronischen Module können ganz oder teilweise integriert sein.The above electronic modules can be fully or partially integrated.

Diese Erfindung enthält also folgende neue Merkmale:
This invention therefore contains the following new features:

  • 1. Einbau eines festen oder Einstecken eines auswechselbaren digitalen Halbleiterspeichermediums in eine Vorrichtung, deren Abmessungen denen einer Compactcassette entspricht.1. Installation of a fixed or insertion of a replaceable digital Semiconductor storage medium in a device, the dimensions of which one Compact cassette corresponds.
  • 2. Die o.g. Vorrichtung enthält alle elektronischen aktiven oder passiven Bauelemente, die zum Auslesen, Konvertieren und zur Übertragung der gespeicherten Daten notwendig sind.2. The above Device contains all electronic active or passive components for reading, converting and transferring the stored data are necessary.
  • 3. Die Vorrichtung kann über eine Fernbedienung und/oder mittels der Detektierung des Zustandes des Cassettenlaufwerkes bedient werden.3. The device can be operated by remote control and / or by means of the detection of the Condition of the cassette drive.
