Da, wie bereits oben erwähnt, der CRT-Controller 5 sich im Videoaufzeichnungsgerät befindet, können ihm zusätzlich noch Daten über die Spieldauer des verwendeten Aufzeichnungsmediums, beispielsweise der eingelegten Magnetbandkassette eines Videorecorders, eingegeben werden, was beispielsweise automatisch Uber mechanische, die Magnetbandkassette abtastende Kontakte erfolgen kann.Since, as already mentioned above, the CRT controller 5 is in the video recording device is located, it can also provide him with data on the playing time of the recording medium used, for example, the inserted magnetic tape cassette of a video recorder, entered be what, for example, automatically via mechanical, the magnetic tape cassette Sensing contacts can be made.
Sind die fUr ein Aufnahmeereignis erforderlichen Schaltfunktionen vollständig eingegeben (Kanal, Einschalt- und Ausschaltzeit, Datum), so berechnet der Uhrencomputer 3 die resultierende noch vorhandene Reserve an Aufzeichnungsmedium (im vorliegenden Beispiel die Bandreserve) und stellt diese Reserve ebenfalls über den Computer dar.Are the switching functions required for a recording event fully entered (channel, switch-on and switch-off time, date), calculated in this way the watch computer 3 the resulting remaining reserve of recording medium (in this example the band reserve) and provides this reserve also via the computer.
Zeigt es sich, daß der Benutzer des Aufzeichnungsgerätes versehentlich die Spieldauer des Aufzeichnungsmediums Uberzogen hat, kann beispielsweise ein Schriftzug "Reserve" blinkend dargestellt und die Uberzogene Zeitdauer mit einem Minuszeichen gemeldet werden.If it turns out that the user of the recording device inadvertently has exceeded the playing time of the recording medium, for example, a lettering "Reserve" shown flashing and the excessive time with a minus sign be reported.
DarUber hinaus ist es neben den für die Vorprogrammierung bedeutsamen Fakten auch möglich, die Realzeit und ggf.In addition, it is important for preprogramming Facts also possible, the real time and possibly
den Bandzählerstand bei bandförmigem Aufzeichnungsmedium anzuzeigen. Erhält der Computer über den Bandzählerstand eine Information, daß das Magnetband der eingelegten Kassette nicht vollständig zum Anfang zurUckgespult ist, und somit die reale verfügbare Spieldauer kleiner ist, kann dies selbstverständlich bei der Reserveberechnung benutzt werden.display the tape count for tape-shaped recording media. If the computer receives information from the tape counter that the magnetic tape the inserted cassette is not fully rewound to the beginning, and thus the real available playing time is shorter, this can of course be done with the Reserve calculation can be used.
Neben den vorstehend geschilderten Möglichkeiten kann die Darstellung von Programmierdaten auf dem Bildschirm eines Fernsehgerätes auch noch die Archivierung von Videoaufzeichnungen erleichtern. Wird nämlich vor Beginn jeder automatischen Aufzeichnung fUr beispielsweise ca. 10 Sekunden der aktuellste Platz der Bildschirmliste mit aufgenommen, so kann später durch diesen "Titel" Auskunft Uber die Videoaufnahme gewonnen werden.In addition to the options outlined above, the representation archiving of programming data on the screen of a television set facilitate video recordings. Namely, before the start of each automatic Recording of the most recent position in the screen list for approx. 10 seconds, for example recorded, so this "title" provides information about the video recording later be won.
Wird dafür gesorgt, daß das CRT-Videosignal (Ausgangssignal des Signalgenerators 5) mit einer charakteristischen Normabweichung (Kennung) versehen wird, kann durch die Identifikation dieser Abweichung sogar eine automatische Suche der Anfangspunkte der einzelnen Videoaufnahmen erfolgen.Is it ensured that the CRT video signal (output signal of the signal generator 5) is provided with a characteristic standard deviation (identifier), can be done by the Identification of this deviation even an automatic search of the starting points of the individual video recordings.
Neben der vorstehend beschriebenen Wirkungsweise der erfindungsgemdßen Anordnung ist es im Rahmen der rfindung auch möglich, daß das Videoaufzeichnungs- und Wiedergabegerät ein von einem Sender abgegebenes Videosignal, vorzugsweise ein Testbildf als Synchronprogramn empfängt und verarbeitet, um dazu die entsprechenden Informationen eines Zeichengenerators einzutasten, was jedoch einen höheren schaltungstechnischen Aufwand erfordert.In addition to the above-described operation of the inventive Arrangement, it is also possible within the scope of the invention that the video recording and playback device a video signal emitted by a transmitter, preferably a Testbildf receives and processes as Synchronprogramn in order to do this the appropriate To key in information from a character generator, which, however, has a higher level of circuitry Requires effort.
