In einem Programmkennungsspeicher sind andererseits die vom Benutzer gewünschten Programme mit entsprechenden Kennungsdaten eingespeichert. Durch Vergleich der Kennungsdaten wird dann der Tuner über eine Abstimmstufe so lange abgestimmt, bis das empfangene Programm mit dem eingespeicherten Programm übereinstimmt. Mit Hilfe dieser Schaltungsanordnung kann z. B. eine zu einem späteren Zeitpunkt ausgestrahlte Sendung dann automatisch aufgezeichnet werden, d. h. es findet eine Vorprogrammierung statt. Wird andererseits das Gerät eingeschaltet, ohne daß der Benutzer sich vorher auf ein bestimmtes Programm festgelegt hat, so besteht die Wahrscheinlichkeit, daß der Benutzer von ihm favorisierte Programme auf anderen Kanälen übersieht.From DE 33 07 885 C2, for example, a Circuit arrangement for program selection in a television / radio receiver or for a videotape recorder in which a channel signal detector programs on receives different channels and determines their identifier. In a program identifier memory, on the other hand, are from the User desired programs with corresponding identification data stored. By comparing the identification data is then the Tuner tuned over a tuning step as long as that received program with the stored program matches. With the help of this circuit z. B. a broadcasted at a later time broadcast then be recorded automatically, d. H. it finds one Pre-programming takes place. On the other hand, the device switched on without the user being on a previously has defined a specific program Probability that the user favored it Programs on other channels overlooks.
Der Erfindung liegt die Aufgabe zugrunde, eine Schaltungsanordnung der vorstehend genannten Art so weiterzugeben, daß dem Benutzer automatisch Programme nach der von ihm gewünschten Priorität dargeboten bzw. diese automatisch aufgezeichnet werden. The invention is based on the object, a circuit arrangement of the aforementioned type so that the Users automatically programs according to the one he desires Prioritized or automatically recorded.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Patentanspruches 1.The solution to this problem arises from the Features of claim 1.
Die erfindungsgemäße Schaltungsanordnung sucht Fernseh- oder Rundfunkprogramme von den verschiedenen Stationen, zeigt diese Programme auf einem Fernsehschirm oder einer Anzeige eines Rundfunkgerätes an und stellt sich automatisch auf denjenigen Kanal ein, der ein vom Benutzer gewünschtes Programm ausstrahlt. Ferner steuert diese Schaltungsanordnung die Aufzeichnung auf einem Videoband derart, daß bei der Aufzeichnung unerwünschte empfangene Werbesendungen ausgelassen werden. Mit Hilfe der Erfindung werden somit unerwünschte Informationen ausgeblendet. Die Erfindung vermeidet somit die vorstehend genannten Nachteile bekannter Anordnungen. Die erfindungsgemäße Schaltung findet die gewünschten Programme anhand ihrer entsprechenden Merkmale oder Kennzeichen und ordnet sie nach der gewünschten Präferenz des Benutzers für die Abspeicherung. Gemäß dieser Ordnung wird automatisch der gewünschte Kanal für den Empfang oder die Aufzeichnung auf einem Band abgestimmt, das derart gesteuert wird, daß unerwünschte Signale von der Aufzeichnung ausgeschlossen werden, während nach Durchlauf der unerwünschten Signale die Aufzeichnung wieder aufgenommen wird.The circuit arrangement according to the invention seeks television or Broadcasting programs from the various stations, this shows Programs on a TV screen or a display of a Radio and automatically adjusts to those Channel that emits a program desired by the user. Furthermore, this circuit controls the recording a videotape such that when recording unwanted received commercials are omitted. With the help of Invention thus become undesirable Information hidden. The invention thus avoids the above mentioned disadvantages of known arrangements. The inventive Circuit finds the desired programs by their corresponding characteristics or characteristics and assigns them according to the desired preference of the user for the storage. According to this order, the desired channel automatically becomes tuned for reception or recording on a tape, which is controlled so that unwanted signals from the Record are excluded while after the run unwanted signals recording is resumed.

Die Erfindung wird nachstehend anhand der Zeichnung näher erläutert. Es zeigen: The invention will be described below with reference to the drawing explained. Show it:
Fig. 1 ein Gesamtschaltbild der Schaltungsanordnung, Fig. 1 is an overall diagram of the circuit arrangement,
Fig. 2 eine beschreibende Darstellung der Arbeitsweise eines Fernsehempfängers, der die Schaltungsanordnung verwendet, und Fig. 2 is a descriptive diagram of the operation of a television receiver using the circuit, and
Fig. 3A und B Flußdiagramme zur Veranschaulichung der Funktion der Schaltungsanordnung in bezug auf Fernsehempfänger und Videorecorder. Fig. 3A and B are flowcharts for illustrating the operation of the circuit arrangement with respect to the television receiver and VCR.
Fig. 1 zeigt die gesamte Anordnung mit einem Fernseh-/ Rundfunkprogrammdetektor, einer Selbstabstimmschaltung zur Kanalwahl und einer Bandsteuerung eines Videorekorders für die Aufzeichnung. Ein Kanalsignaldetektor 1 detektiert alle (Programm-)Kanalsignale von den Sendestationen, leitet diese zu einer Hochfrequenzverstärkerschaltung in einem üblichen Fernsehempfänger TV und auch zu einem die von dem Benutzer gewünschten oder favorisierte Programmkennungen speichernden Speicher 2 und zu der Kanalanzeigesteuerschaltung 3 für eine Anzeige der Kanäle. Die Kanalanzeigesteuerschaltung 3 ist mit der Anzeigeeinheit 4 und dem Speicher 2 verbunden, der wiederum mit der Selbstabstimmschaltung 5 in Verbindung steht, die an den Empfangsoszillator im Fernsehempfänger angeschlossen ist. Der Speicher 2 steht auch mit der Videorecordersteuerung 6 in Verbindung mit einem weiteren Anschluß zum Videoantriebsmotor. Fig. 1 shows the entire arrangement with a television / radio program detector, a self-tuning circuit for channel selection and a tape control of a video recorder for recording. A channel signal detector 1 detects all (program) channel signals from the transmitting stations, routes them to a high-frequency amplifier circuit in a conventional television receiver TV and also to a memory 2 storing the user's desired or favored program identifiers and to the channel display control circuit 3 for display of the channels. The channel display control circuit 3 is connected to the display unit 4 and the memory 2 , which in turn communicates with the auto-tuning circuit 5 which is connected to the local oscillator in the television receiver. The memory 2 is also connected to the video recorder controller 6 in connection with another connection to the video drive motor.
Nachstehend wird nun unter Bezugnahme auf die Zeichnungen die Arbeitsweise und die Funktion der Schaltungsanordnung näher beschrieben.Hereinafter, with reference to the drawings Operation and the function of the circuit arrangement described in more detail.
Eine Antenne nimmt die von den Sendestationen ausgestrahlten elektromagnetischen Wellen auf und der Kanalsignaldetektor 1 findet alle Programme in den empfangenen Wellen aufgrund von Programmerkmalen oder Programmkennungen (z. B. Filme, Schauspiele, Shows, Werbesendungen usw.). Die vom Detektor 1 zum Speicher 2 gesandten Signale werden mit denjenigen Programmkennungen in dem Speicher 2 verglichen, die der Benutzer favorisiert, um die Prioritätsreihenfolge der Abstimmung festzulegen. Die vorgenommene Kanalauswahl wird in Form von Steuersignalen an die Selbstabstimmschaltung 5 angelegt, so daß diese Ausgangssignale zur Abstimmung des Empfangsoszillators abgibt und die Selbstabstimmung vorgenommen wird.An antenna picks up the electromagnetic waves radiated from the transmitting stations, and the channel signal detector 1 finds all the programs in the received waves due to program features or program identifiers (e.g., movies, plays, shows, commercials, etc.). The signals sent from detector 1 to memory 2 are compared with those program identifiers in memory 2 which the user favors to determine the priority order of the tuning. The channel selection made is applied to the auto-tuning circuit 5 in the form of control signals, so that it outputs output signals for tuning the local oscillator and the self-tuning is performed.
Die Ausgangssignale des Detektors 1 werden auch über die Kanalanzeigesteuerschaltung 3 der Anzeigeeinheit 4 zugeführt, um eine visuelle Darstellung der Auswahl zu geben, sowie die ferngesteuerten Signale dem üblichen Empfangsoszillator gemäß der Präferenz oder Priorität der Speicherinhalte gemäß Fig. 2 (ra) anzulegen.The output signals of the detector 1 are also supplied through the channel display control circuit 3 to the display unit 4 to give a visual representation of the selection and to apply the remote control signals to the usual local oscillator according to the preference or priority of the memory contents of Fig. 2 (ra).
Soll lediglich der Inhalt eines Programms aufgezeichnet werden, dann bewirkt das über die Leitung 7 an den Programmkennungsspeicher 2 von dem Detektor 1 angelegte Merkmalssignal, daß der Speicher 2 ein Ausgangssteuersignal an die Videobandaufzeichnungssteuerung 6 abgibt und der Videobandantriebsmotor zur Steuerung des Videobandes aktiviert wird. Intended merely to the contents of a program to be recorded, then effected via the line 7 to the program identifier memory 2 applied from the detector 1 feature signal that the memory 2 outputs an output control signal to the video tape recorder controller 6 and the video tape drive motor for controlling the video tape is activated.
Als Beispiel wird zunächst auf folgende Tabelle I Bezug genommen.As an example, reference is first made to the following Table I.
Es wird somit einerseits angenommen, daß die verschiedenen Senderstationen ihre entsprechenden Programme gemäß der Tabelle I abstrahlen. Zum anderen sei angenommen, daß der Benutzer den verschiedenen Programmarten eine Prioritätsordnung zuteilt, wie sie aus Tabelle II ersichtlich ist.It is therefore assumed on the one hand that the different Sender stations their corresponding programs according to Table I. radiate. On the other hand, it is assumed that the user the allocates a priority order to different types of programs, such as it can be seen from Table II.
Unter diesen Annahmen stellt sich der Fernsehempfänger beim Einschalten automatisch auf den Kanal 2 (Tabelle I) ein, so daß der Benutzer den laufenden Film anschauen kann.Under these assumptions, the television receiver adjusts itself Automatically turn on channel 2 (Table I) so that the user can watch the movie in progress.
Beginnt jedoch nach einem ersten Filmteil ein Werbespot, dann schaltet die Selbstabstimmung automatisch auf den Kanal 4 um, so daß das Showprogramm wiedergegeben wird. Läuft dann nach Abschluß der Werbesendungen der Film wieder an und wird fortgesetzt, dann kehrt der Empfang automatisch vom Kanal 4 auf den Kanal 2 zurück und es wird der nächste Filmteil wiedergegeben.However, after a first movie part starts a commercial, then automatically switches self-tuning to channel 4, so that the show program is played. Then runs to completion the commercials the movie again and will continue, then the reception returns automatically from channel 4 to channel 2 and it will play the next movie part.
Am Ende des Films erfolgt wiederum automatisch eine Abstimmung auf Kanal 4 gemäß der Prioritätsreihenfolge im Speicher 2 (Tabelle II), so daß die Show zu sehen ist. Hat dabei der Videorecorder den Film aufgenommen, dann wäre die Aufzeichnung beim Umschalten auf den Kanal 4 unterbrochen und erst bei erneuter Abstimmung auf den Kanal 2 wieder aufgenommen worden.At the end of the movie, a vote is again automatically made on channel 4 according to the order of priority in memory 2 (Table II) so that the show can be seen. If the video recorder has recorded the film, then the recording would be interrupted when switching to the channel 4 and only resumed on re-tuning to the channel 2.
Fig. 2 erläutert anhand von beschrifteten Feldern die Funktion eines das erfindungsgemäße System verwendenden Fernsehempfängers. Die in dem Speicher 2 gespeicherten Anfangszustände ergeben sich aus den Fig. 2 (ga) und (na), während die augenblicklich empfangenen Sendungen in Fig. 2 (da) dargestellt sind und die Fig. 2 (ra) automatisch die Vorderseite des Fernsehempfängers wiedergibt. Fig. 2 illustrates the function of a television receiver using the system according to the invention on the basis of labeled fields. The initial states stored in the memory 2 are shown in Figs. 2 (ga) and (na) while the presently received transmissions are shown in Fig. 2 (da) and Fig. 2 (ra) automatically reproduces the front of the television receiver ,
In Fig. 1 sind die einzelnen Einheiten des Fernsehempfängers TV und des Videorekorders VCR mit Angabe ihrer Funktion gezeigt. Da diese Einheiten dem Fachmann bekannt sind, sollen sie nicht mehr im einzelnen erläutert werden.In Fig. 1, the individual units of the television receiver TV and the video recorder VCR are shown with indication of their function. Since these units are known to those skilled in the art, they should not be explained in detail.
