Abstract

The decoding system is of modular design, with a facility for subsequent incorporation in prepared VHF and TV receivers. Thus the receivers can evaluate program-accompanying, or program-simulating RDS, NICAM, D2-MAC etc. data. Pref. the system contains a Prager decoder so that the entire system is suitable for transmission of Alpha numeric messages, switching signals, tuning data etc. to a classifiable USW or TV receiver, using radio, cable, link and/or satellite paths. The used systems are typically fitted in housings with an outer dimension of a commercial audio cassette. ADVANTAGE - Enables data instead of audio signals to be fed and evaluated at reception side.

Description

Neue digitale Technologien erlauben es, in unhörbarer Weise progammbegleitende Daten im Hörfunk und im Tonkanal des TV-Rundfunks übertragen zu können. Andererseits ist es - zwecks Aufbau eines Datenübertragungssystems - möglich, Daten anstelle des Audiosignals einzuspeisen und auf der Empfangsseite auszuwerten.New digital technologies make it possible to inaudibly accompany the program Broadcast data in radio and audio channels of TV broadcasting to be able to. On the other hand, it is - for the purpose of building a data transmission system - possible to feed in data instead of the audio signal and evaluate on the reception side.

RDS RADIO PAGINGRDS RADIO PAGING

Das RDS Radio Paging nach supplement 2 der EBU 3244-E ermöglicht eine Adressierbarkeit des UKW-Empfängers (Personenrufsystem). So können z. B. Systeme nach Anspruch 2. mit Hilfe von UKW- Rundfunk bequemRDS radio paging according to supplement 2 of the EBU 3244-E enables one Addressability of the VHF receiver (paging system). So z. B. Systems according to claim 2. with the help of FM Broadcasting conveniently

  • - alle Ampeln einer Stadt ferngesteuert- Remote control of all traffic lights in a city
  • - Fahraufträge an Taxifahrer angezeigt oder- Driving orders displayed to taxi drivers or
  • - diverse einseitig gerichtete Punkt-zu-Punkt-Datenverbindungen aufgebaut werden.- Various one-way point-to-point data connections being constructed.

Die Einspeisung des RDS Radio Paging-Datenstroms in das NICAM- bzw. NICAM/D2-MAC-System wiederum ermöglicht die drahtlose oder drahtgebundene Datenübertragung an einzeln adressierbare bzw. klassifizierbare TV-Empfänger. So kann z. B. mit diesem System der Descrambler eines zahlungssäumigen TV-Abonnenten (Pay-TV) ferngesteuert abgeschaltet werden (Patentanmeldung Rohde & Schwarz v. 8. 12. 89). Anspruch 2 ermöglicht die einfache empfängerseitige Realisierung dieses Systems.The feeding of the RDS radio paging data stream into the NICAM or NICAM / D2 MAC system in turn enables wireless or wired Data transmission to individually addressable or classifiable TV receivers. So z. B. with this system of descramblers of a paying TV subscriber (Pay-TV) can be switched off remotely (patent application Rohde & Black v. 8. 12. 89). Claim 2 enables the simple receiver side Realization of this system.

Die Erfindung nach Anspruch 3 bietet die Möglichkeit, vorhandene Cassettenschächte für die platzmäßige Unterbringung des Decoders zu nutzen.The invention according to claim 3 offers the possibility of existing Cassette slots to accommodate the decoder use.

Es zeigt Fig. 1 die Lösung nach Anspruch 3. Ein cassettenförmiger Decoder 1 befindet sich in einem Schicht 7 eines Heim- oder Autoempfängers. Die Unterscheidung zu einer normalen Cassette wird mit einem mechanischen oder elektrischen Sensor 2 festgestellt und damit die Motorspannung unterbrochen und andere Funktionen eingeschaltet. Die elektrische Schnittstelle zum Empfänger wird mittels eines Steckers 3 o. ä. realisiert. Bei einem Heimempfänger wird die 8- od. mehrstellige Anzeige 4 im Klarsichtbereich des Cassettenschacht-Deckels plaziert. Im Falle Autoradio kann die 8- od. mehrstellige Anzeige 5 in Stecktechnik hinzugefügt werden, z. B. über ein Flachkabel 6.It shows Fig. 1, the solution according to claim 3. A tape-shaped decoder 1 is located in a layer 7 of a home or car receiver. The distinction from a normal cassette is determined with a mechanical or electrical sensor 2 , thus interrupting the motor voltage and switching on other functions. The electrical interface to the receiver is implemented using a plug 3 or the like. For a home receiver, the 8 or multi-digit display 4 is placed in the clear area of the cassette cover. In the case of car radio, the 8- or multi-digit display 5 can be added using plug-in technology, e.g. B. via a flat cable 6 .

Der Decoder nach Anspruch 3 kann bei Nichtbenutzung - z. B. beim Abspielen einer Toncassette- im Cassettenfach untergebracht werden.The decoder according to claim 3 can be used when not in use - e.g. B. at Play a cassette in the cassette compartment.
