Abstract

The invention relates to a system that comprises a TV classification signal receiver and a TV source switch, which allows to suppress certain program contents in cable networks or to replace them by a defined signal. The system can be used for suppressing images of sex or violence or advertising in hotel cable networks or in the cable networks of hospitals. Undesired program contents can be replaced in the cable head-end by desired programs, for example by an information channel which informs about the facility (hotel environment, hospital services).

Description

TV-Signalquellen-Umschalter TV signal source switch
Beschreibungdescription
Die Erfindung bezieht sich auf einen TV-Signalquellen- Umschalter für KabelkopfStationen.The invention relates to a TV signal source switch for cable head stations.
Kabelnetze bestehen aus einem Signalverteilnetz und einer Kopfstation, in der die Kanalbelegung definiert wird. In dieser Kopfstation werden die oftmals über Satellit empfangenen TV-Kanäle den einzelnen Frequenzbereichen zugeordnet. Hierzu verwendet man meist Modulatoren, damit man jeden TV-Kanal einer bestimmten Frequenz im Kabelnetz zu- ordnen kann.Cable networks consist of a signal distribution network and a head-end station in which the channel assignment is defined. The TV channels, which are often received via satellite, are assigned to the individual frequency ranges in this head-end station. For this purpose, modulators are mostly used so that each TV channel can be assigned to a specific frequency in the cable network.
Am Ausgang der KopfStation befindet sich ein Kabel, welches auf verschiedenen Frequenzen sämtliche TV- Programminhalte transportiert. Aus der DE 43 03 942 AI ist es bekannt, eine selektive Steuerung je nach Programminhalt (Genre; Werbung; Sex-, Gewaltszenen) zu ermöglichen. Weiterhin werden in dieser Druckschrift Set-Top- Boxen offenbart, die Informationen über das aktuelle Pro-- gramm aus einem zentralen Studio erhalten. Diese Klassi- fikations-Informationen bestehen u.a. aus Angaben zum aktuellen Programmthema bzw. Genre wie etwa Werbung; Sport; Film; Gewalt; Erotik, etc.. Dieses Gerät ist als Set-Top- Box jedoch für jeden Fernseher notwendig. Bekannt sind ebenfalls KabelkopfStationen und deren Anordnung von Satelliten-Tunern und Modulatoren.At the exit of the head station there is a cable that transports all TV program content on different frequencies. From DE 43 03 942 AI it is known to enable selective control depending on the program content (genre; advertising; sex, violence scenes). Set-top boxes are also disclosed in this publication, which receive information about the current program from a central studio. This classification information consists, among other things, of information on the current program topic or genre, such as advertising; Sports; Movie; Violence; Erotic, etc. This device is necessary as a set-top box for every television. Cable head stations and their arrangement of satellite tuners and modulators are also known.
Diese Lösungen haben jedoch einige technischen Nachteile. Jedes Empfangsgerät benötigt zur Ausblendung unerwünschter Szenen eine eigene Set-Top-Box, welches Zusatzkosten verursacht und dem Bediener eine Einarbeitung abverlangt. In Hotels- und Krankenhäusern ist dies jedoch meist nicht möglich. Zudem kann durch Abbau der Set-Top-Box wieder auf unerwünschte Programminhalte zugegriffen werden.However, these solutions have some technical disadvantages. Each receiving device needs its own set-top box to hide unwanted scenes, which incurs additional costs and demands training from the operator. However, this is usually not possible in hotels and hospitals. In addition, unwanted program content can be accessed again by dismantling the set-top box.
In einem Hotel oder in einem Krankenhaus bedeutet dies, das erhebliche Zusatzkosten auf den Betreiber zukommen.In a hotel or hospital, this means that the operator has to pay considerable additional costs.
Aufgabe der Erfindung ist es, ein kostengünstiges und einfaches Verfahren zu erreichen, mit dem die Bedienung der Empfänger für den Zuschauer gleich bleibt und unerwünschte Programminhalte erst gar keinen Einlass in das Kabelnetz finden. Es sollen auch keine individuellen Ein- Stellungen vorgenommen werden können, sondern das Verhalten der Programmeinspeisung soll für alle Benutzer gleich sein.The object of the invention is to achieve a cost-effective and simple method with which the operation of the receiver remains the same for the viewer and undesired program content does not find its way into the cable network at all. It should also not be possible to make individual settings, but the behavior of the program feed should be the same for all users.
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass die TV-Signalquellen-Umschalter anhand der ProgrammzusatzInformationen, wie z.B. der Klassifikation des TV-Programms in "Werbung" oder "Programm", eine sofortige Umschaltung für jeden einzelnen Programmplatz vornehmen kann, dergestalt, dass für jeden Programmkanal bereits vor Einspei- sung in das Kabelnetz vom Original-Kanal auf einen Ersatzkanal umgeschaltet werden kann, sobald und solange die unerwünschten Programm-Inhalte auf dem Original-Kanal ausgestrahlt werden.According to the invention, the object is achieved in that the TV signal source switch can carry out an immediate switchover for each individual program position on the basis of the additional program information, such as the classification of the TV program in "advertising" or "program", in such a way that for everyone The program channel can be switched from the original channel to a replacement channel before it is fed into the cable network, as soon and for as long the unwanted program content is broadcast on the original channel.
Somit werden unerwünschte Programminhalte direkt an der Quelle ausblendet, also vor Einspeisung in das Kabelnetz. Dies wird zudem noch kostengünstig erreicht. Ferner können die unerwünschten Programminhalte nicht nur ausgeblendet (Schwarzbild) , sondern durch unterhaltsame und nützliche Informationen ersetzt werden.This means that unwanted program content is hidden directly at the source, i.e. before it is fed into the cable network. This is also achieved inexpensively. Furthermore, the unwanted program content can not only be hidden (black screen), but can be replaced by entertaining and useful information.
Folgenden Komponenten werden für Kabelkopf-Stationen als dem Stand der Technik entsprechend vorausgesetzt:The following components are required for state-of-the-art cable head stations:
Satelliten-TunerSatellite Receiver
Modulator - TV-Klassifikations-EmpfängerModulator - TV classification receiver
Steuerungs-PC (Personal-Computer) oder ControllerControl PC (personal computer) or controller
Die genannten grundlegenden Nachteile bisheriger Set-Top- Box-Lösungen werden durch die Anordnung und Teilkomponen- ten der Erfindung umgangen. Folgende Vorteile stellen sich heraus:The basic disadvantages of previous set-top box solutions mentioned are avoided by the arrangement and subcomponents of the invention. The following advantages emerge:
1. Die Gesamtkosten verringern sich drastisch.1. The total cost is drastically reduced.
2. Die Wartung reduziert sich auf eine zentral zugäng- liehe Stellung.2. Maintenance is reduced to a centrally accessible position.
3. Der End-Benutzer bedient wie gewohnt ohne Einweisung per Fernbedienung.3. The end user operates as usual without instruction by remote control.
4. Die Qualität der Steuerung ist vorhersagbar und niemals zufällig, die Qualität daher gleich bleibend. 5. Das System kann nicht umgangen werden 6. Das System ist einfach nachrüstbar. 7. Das System ist nahezu wartungsfrei.4. The quality of the control is predictable and never random, so the quality remains the same. 5. The system cannot be bypassed. 6. The system can be easily retrofitted. 7. The system is almost maintenance free.
Erreicht werden diese Vorteile durch eine neuartig Kombination folgender Teilmaßnahmen:These advantages are achieved by a new combination of the following sub-measures:
1. Der TV-Klassifikations-Empfänger wird zentral in der KabelkopfStation oder am Einspeisepunkt des Kabel- netzes angebracht.1. The TV classification receiver is attached centrally in the cable head station or at the entry point of the cable network.
2. Der TV-Klassifikations-Empfänger versorgt eine zen- tral im PC oder in einem Controller geführte Sendertabelle mit Event-Informationen. Auf diese Weise ist für jeden Kanal ein Status abrufbar z.B. "Werbung Ja/Nein" oder "Jugendfrei Ja/Nein" .2. The TV classification receiver supplies event information centrally to a transmitter table that is managed in the PC or in a controller. In this way, a status can be called up for each channel, e.g. "Advertising Yes / No" or "Family Yes / No".
3. Je nach Status eines Senders unterbricht der Con- troller die Zuführung dieses Kanals durch Umschalten des Modulators auf das Ersatzprogramm.3. Depending on the status of a transmitter, the controller interrupts the supply of this channel by switching the modulator to the replacement program.
4. Das Ersatzprogramm besteht z.B. aus einem definierten problemfreien Programm (also einem TV-Sender der jedrzeit werbefrei und jeugendfrei ist) oder aus einem selbst erzeugten Info-Kanal, der ständig Informationen zu Sehenswürdigkeiten der Stadt oder zu Einkaufsmöglichkeiten bietet.4. The replacement program is e.g. from a defined problem-free program (i.e. a TV station that is always free of advertising and free of youth) or from a self-generated info channel that constantly provides information on sights of the city or on shopping opportunities.
Der der Erfindung zu Grunde liegende Gedanke wird in der nachfolgenden Beschreibung anhand eines Ausführungsbei- spiels, das in den Zeichnungen dargestellt ist, näher beschrieben. Es zeigen:The idea on which the invention is based is described in more detail in the following description with reference to an exemplary embodiment which is illustrated in the drawings. Show it:
Fig. 1 eine schematische Darstellung der Verfahrens- weise gemäß dem Stand der Technik und Fig. 2 eine schematische Darstellung der Verfahrensweise unter Verwendung von erfindungsgemäßen TV-Signalquellen-Umschaltern.1 is a schematic representation of the procedure according to the prior art and Fig. 2 is a schematic representation of the procedure using TV signal source switches according to the invention.
Die Steuersoftware erlaubt die Eingabe des Umschaltverhaltens (Sex- und Gewaltszenen oder nur ganze Filme ausblenden; Werbung ausblenden etc.) und die Angabe, woher die TV-Programmklassifikationen empfangen werden (z.B. Internet-Adresse) .The control software allows you to enter the switching behavior (sex and violence scenes or only hide entire films; hide advertisements, etc.) and specify where the TV program classifications are received from (e.g. Internet address).
Danach schaltet die Steuerungseinheit die jeweiligen Umschalter ein oder aus . Im eingeschalteten Zustand wird auf die jeweilige Kabel-Frequenz das Ersatzprogramm auf- moduliert. Im ausgeschalteten Zustand wird das Original- TV-Programm wie gehabt aufmoduliert.The control unit then switches the respective changeover switch on or off. When switched on, the replacement program is modulated onto the respective cable frequency. When switched off, the original TV program is modulated as usual.
Die beiden genannten Ausgestaltungsbeispiele unterscheiden sich je nach Einspeisung über Satellit oder über Breitbandkabelnetz. In der Zeichnung wird eine Satelli- ten-KabelkopfStation beschrieben. Bei Einspeisung über Breitbandkabelnetz, sind statt Satelliten-Tuner einfache Kabeltuner notwendig, um das Mischsignal in Einzelkanäle zu zerlegen. The two design examples mentioned differ depending on the feed-in via satellite or via broadband cable network. A satellite cable head station is described in the drawing. When feeding in via broadband cable network, simple cable tuners are required instead of satellite tuners in order to break down the mixed signal into individual channels.
