Abstract

A method for the synchronous recording of information signals on a recording medium and, in particular, a method for the synchronous post-audio dubbing of a pre- recorded magnetic video tape consists in the fact that, before the synchronous recording is started, a start- related time code is recorded onto the recording medium to be pre-recorded. This enables a rapid access to the desired start address of a magnetic video tape, without recording a VITC signal.

 zum Film-Tonschnitt auf AUDIO SPUR 1 und 2 im Einsetz-Schnittverfahren durchzuführen. Die Zeitcodeaufzeichnung bleibt dabei erhalten. Nachfolgend kann, kompatibel mit dem startbezogenen Zeitcode, von jedem Synchronstudio ein Internationales Tonband (Geräuschband ohne Sprache) hergestellt werden. In weiterer Folge kann die Abmischung mit einer entsprechenden Sprache erfolgen. 



   Auch kann, gesteuert von der nun in jeder Aufzeichnung integrierten stetig von 09 59 50 00 startbezogenen, stetig aufsteigenden Zeitcode-Information, im Studio die Videobandmaschine oder eine Filmprojektionsmaschine ab dem Norm-Startpunkt, welcher, bedingt durch die ständig gleiche Adresse, jederzeit reproduzierbar ist, bildgenau synchron zugeschaltet und der Ton, also mit den bewährten Methoden der Filmtechnik, sendefertig gemischt werden. 



   Ein weiterer Vorteil besteht darin, dass mit Hilfe eines Zeitcodelesers jederzeit die bereits bespielte Länge (von Bildbeginn NULL an) bzw. die Restlänge des Bandes abgelesen werden kann. 



  Auch ist es einfach, zusätzliche Signale an jeder gewünschten Stelle des Bandes einzusetzen oder gewisse Stellen zu löschen und dort andere Signale aufzuzeichnen. 



   Mit der Anwendung der Erfindung kann erreicht werden, dass in jedem Studio ein genormter Start ohne spezielle Programmierung erreicht bzw. synchron reproduzierbar gemacht wird. 



   Die 6 s Hochlaufzeit wurden zuerst mit Rücksicht auf die zur Zeit gängigen Filmprojektionsmaschinen festgelegt. Da in einem modernen Studio eine sehr grosse Anzahl von Maschinen synchron

   Es sind natürlich auch andere Zeitwerte für die Startadresse, jeweils mit Rücksicht auf den technisch notwendigen Vorlauf, denkbar. Die Bedingung hiefür ist immer ein exakter Beginn der Informationsaufzeichnung bei dem Zeitwert 10 00 00 00 mit anschliessend ständig aufsteigendem Zeitwert. 



    PATENTANSPRÜCHE :    
1. Verfahren zur synchronen Aufzeichnung von Informationssignalen auf einem Aufzeichnungsmedium, dadurch gekennzeichnet, dass vor dem Start der synchronen Aufzeichnung ein startbezogener Zeitcode auf das zu bespielende Aufzeichnungsmedium aufgezeichnet wird.

 for film sound editing on AUDIO SPUR 1 and 2 using the insert editing process. The time code recording is retained. In the following, compatible with the start-related time code, an international tape (noise band without speech) can be produced by each dubbing studio. Subsequently, the mixing can be done with an appropriate language.



   Also, controlled by the time code information that is now continuously start-up-related from 09 59 50 00 in every recording, the video tape machine or a film projection machine can be reproduced in the studio from the standard start point, which, due to the constantly identical address, can be reproduced at any time , switched on synchronously and the sound, that is, with the proven methods of film technology, can be mixed ready for broadcast.



   Another advantage is that with the help of a time code reader the length already recorded (from the beginning of the picture ZERO) or the remaining length of the tape can be read.



  It is also easy to insert additional signals at any desired point on the tape or to delete certain points and record other signals there.



   With the application of the invention it can be achieved that a standardized start is achieved in each studio without special programming or made synchronously reproducible.



   The 6 s ramp-up time was first determined with regard to the currently used film projection machines. Because in a modern studio a very large number of machines are synchronized

   Of course, other time values for the start address are also conceivable, each taking into account the technically necessary lead time. The condition for this is always an exact start of the information recording at the time value 10 00 00 00 followed by a continuously increasing time value.



    PATENT CLAIMS:
1. A method for the synchronous recording of information signals on a recording medium, characterized in that a start-related time code is recorded on the recording medium to be recorded before the start of the synchronous recording.

2. Verfahren zur synchronen Aufzeichnung nach Anspruch 1, dadurch gekennzeichnet, dass der startbezogene Zeitcode ein Longitudinal-Zeitcode ist, dessen Aufzeichnung bei einer vorgegebenen, ständig gleichen Startadresse mit dem Zeitwert 09 59 50 00 bzw. 09 59 54 00 entsprechend einem Speichermediumvorlauf von 10 bzw. 6 s bis zum Aufzeichnungsbeginn der Informationssignale synchron zu einer optischen START-Anzeige beginnt.  2.

Verfahren zur synchronen Aufzeichnung nach Anspruch 1 oder 2, wobei der startbezogene Zeitcode auf einem MASTER-STARTVORLAUFBAND aufgezeichnet wird, dadurch gekennzeichnet, dass dieser kalibrierte MASTER-STARTVORLAUF im Rahmen eines normalen Kopiervorganges auf das zu bespielende Aufzeichnungsmedium übertragen wird.  3. The method for synchronous recording according to claim 1 or 2, wherein the start-related time code is recorded on a MASTER-STARTVORLAUFBAND, characterized in that this calibrated MASTER-STARTVORLAUF is transferred to the recording medium to be recorded as part of a normal copying process.
