Description

Die Erfindung betrifft eine Einrichtung zum automatischen Ausblenden von Werbebeiträgen oder anderen unerwünschten Abschnitten aus laufenden Fernsehsendungen gemäß dem Oberbegriff aus Patentanspruch 1.The invention relates to a device for automatically hiding advertising articles or other undesirable sections from current television programs in accordance with the Preamble from claim 1.

Die von vielen Sendeanstalten in die laufenden Sendungen eingeschobenen Werbebeiträge werden von den meisten Zuschauern als störende Unterbrechung empfunden. Insbesondere bei der Aufzeichnung von Sendungen auf Videoband entsteht noch zusätzlich ein unnötiger Bandmehrverbrauch. Hier bietet es sich an, das Band schon bei der Aufnahme für die Dauer dieser Werbeeinschübe anzuhalten und die Aufnahme danach wieder fortzusetzen.The advertising contributions inserted by many broadcasters into the current programs are perceived as a disturbing interruption by most viewers. Especially at the recording of programs on videotape also creates an unnecessary one Additional tape consumption. Here it makes sense to start the tape for the duration pause these inserts and then resume recording.

Das zentrale Problem ist dabei die Identifikation der unerwünschten Szenen oder Beiträge. Es sind Vorschläge bekannt, wo mit Hilfe von Bildspeichern das Anfangsbild des Beitrags durch Vergleich erkannt werden soll (DE 41 06 246 C1). Dieses System ist aber teuer und von der Sendeanstalt leicht zu unterlaufen indem einfach jeder Werbeblock mit einem anderen Anfangsbild begonnen wird. Ein weiterer Vorschlag (DE 42 05 762 A1) greift auf Änderungen im Ton- und Bildsignal zu, hierbei müssen jedoch aufwendige Verfahren wie Spektralanalysen angewendet werden. Der Nachteil besteht hier in der aufwendigen und damit teuren Analyseelektronik deren Arbeitsweise zudem bei entsprechender Gestaltung der Werbebeiträge durch die Sendeanstalt unterlaufen werden kann.The central problem is the identification of the unwanted scenes or contributions. It Proposals are known where, with the help of image memories, the initial image of the post Comparison should be recognized (DE 41 06 246 C1). This system is expensive and of the Broadcasters easily subvert by simply placing each ad block with a different one Starting picture is started. Another proposal (DE 42 05 762 A1) is based on changes in the sound and image signal, but this requires complex methods such as spectral analysis be applied. The disadvantage here is the complex and therefore expensive Analysis electronics also work with the appropriate design of the advertising contributions can be circumvented by the broadcaster.

Ziel der Erfindung ist die Vermeidung der Aufzeichnung von Werbeeinblendungen oder anderen unerwünschten Abschnitten (wie z. B. Gewaltfilme) in Sendebeiträgen, unabhängig von Übertragungsverfahren, senderseitigen Steuersignalen und der Zeitdauer sowie Gestaltung der Werbebeiträge bei Aufnahmen in An- oder Abwesenheit des Benutzers. Das System soll weiterhin unabhängig von der Fernsehübertragungsnorm arbeiten.The aim of the invention is to avoid the recording of advertisements or others unwanted sections (such as violent films) in broadcasts, regardless of Transmission process, transmitter-side control signals and the duration and design of the Advertising contributions for recordings in the presence or absence of the user. The system is supposed to continue to work independently of the television broadcasting standard.

Dieses Ziel wird erfindungsgemäß mit einer Einrichtung nach Patentanspruch 1 erreicht.This object is achieved according to the invention with a device according to claim 1.

Der Erfindung liegt die Idee zugrunde, daß die Identifikation der auszublendenden Abschnitte in einer zentralen Stelle und nicht im Kundengerät stattfindet sowie insbesondere der vom Fernsehkanal unabhängigen Übertragung der Steuercodes an die Kunden.The invention is based on the idea that the identification of the sections to be hidden takes place in a central location and not in the customer device and in particular that of TV channel independent transmission of tax codes to customers.

Damit werden folgende Vorteile erreicht:The following advantages are achieved:

  • - Keine aufwendige Identifikationsschaltung, d. h. preiswertes Endgerät- No complex identification circuit, d. H. inexpensive device
  • - das System ist durch eine Änderung in der Gestaltung der Werbebeiträge nicht manipulierbar- The system cannot be manipulated due to a change in the design of the advertising contributions
  • - das System bietet eine nahezu 100-prozentige Identifikationssicherheit- The system offers almost 100 percent identification security
  • - Es können auch Gewaltfilme ausgeblendet werden.- Violent films can also be hidden.
  • - einfache Steuerzentrale: Es werden nur ein Fernsehempfangsanschluß, Überwachungs­ monitore, ein Telefonanschluß, ein Rechner und eine Eingabeeinheit benötigt.- Simple control center: there will only be a television reception connection, surveillance monitors, a telephone connection, a computer and an input unit are required.
  • - unabhängig von der Fernsehübertragungsnorm.- regardless of the television broadcasting standard.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Developments of the invention are the subject of the dependent claims.

Die Erfindung wird im folgenden näher beschrieben und erläutert.The invention is described and explained in more detail below.

Die Fig. 1 zeigt in vereinfachter Darstellung das Blockschaltbild der erfindungsgemäßen Einrichtung mit dem zu steuernden Videorecorder. Fig. 1 shows a simplified representation of the block diagram of the inventive apparatus with the to be controlled video recorder.

Die Programmkanäle werden in einer Überwachungszentrale (1) auf Monitoren wiedergegeben. Beginnt oder endet nun auf einem Kanal ein Werbebeitrag, so wird vom Beobachter manuell ein Bedienelement der Eingabeschalteinheit (2) betätigt. Ein Rechner (3) setzt diese Information in ein Signal um, das die Zugehörigkeit zu einem bestimmten Kanal und den Status (Ausblenden/nicht Ausblenden) enthält und dann über ein Modem (4) dem Übertragungskanal zugeführt wird. Die Übertragung zu den Empfangseinheiten (7) kann dabei drahtgebunden (5) oder drahtlos (6) sein. Es wird jedenfalls ein vom Fernsehkanal unabhängiger Weg gewählt. Als Übertragungswege kommen u. A. die Rundsteuerungen der Energieversorgungs­ unternehmen, Cityrufsysteme, Funknetze und ähnliche Einrichtungen in Frage. Diese Übertragungsverfahren garantieren die Erreichbarkeit praktisch aller Teilnehmer und sind störsicher. In den Empfangseinheiten (7) werden die Steuersignale einem Decoder (8) zugeführt. Dieser stellt dann die Information der Steuereinheit (9) zur Verfügung, die schließlich die Ansteuerung des Videorecorders (10) vornimmt. Die Steuereinheit ordnet dabei die Information dem jeweils gewünschten (aufzunehmenden) Fernsehkanal zu und leitet den Steuerbefehl in geeigneter Weise (vergl. Unteranspruch 2 und 3) dem zu steuernden Videoaufzeichnungsgerät zu. Die Steuereinheit kann auch einen Ausgleich eines durch den Übertragungsweg bedingten Zeitversatzes (vergl. Unteranspruch 7) herbeiführen.The program channels are displayed on monitors in a monitoring center ( 1 ). If an advertising contribution now begins or ends on a channel, the observer manually actuates an operating element of the input switching unit ( 2 ). A computer ( 3 ) converts this information into a signal which contains the membership of a specific channel and the status (hide / not hide) and is then fed to the transmission channel via a modem ( 4 ). The transmission to the receiving units ( 7 ) can be wired ( 5 ) or wireless ( 6 ). In any case, a path that is independent of the television channel is chosen. As transmission paths come u. A. The ripple controls of the energy supply companies, city call systems, radio networks and similar facilities in question. These transmission methods guarantee the accessibility of practically all participants and are immune to interference. The control signals are fed to a decoder ( 8 ) in the receiving units ( 7 ). This then makes the information available to the control unit ( 9 ), which finally controls the video recorder ( 10 ). The control unit assigns the information to the desired (to be recorded) television channel and passes the control command in a suitable manner (see subclaims 2 and 3) to the video recording device to be controlled. The control unit can also compensate for a time offset caused by the transmission path (cf. subclaim 7).
