Definitions

  • the invention relates to an antenna socket, in particular for attachment to building walls, with a first coaxial socket for extracting TV signals, with a bandstop filter for radio broadcast signals, the output of which is connected to the first coaxial socket, with a second Coaxial socket for taking radio broadcast signals, with a bandpass filter for radio signals, the output of which is connected to the second coaxial socket, with a first connection for a coaxial cable for antenna signal supply, with a second connection for a coaxial cable for antenna signal transmission and with a directional coupler in the form of a line coupler or a transformer coupler, the feed-through line input of which is connected to the first connection.
  • antenna socket is from DE-AS 27 33 200, from DE-PS 27 33 220 and from the Siemens brochure "New antenna sockets - the sum of your and our experience", order no. N285 / 5072. The latter further shows that the antenna sockets contain a directional coupler and filter.
  • an antenna socket is provided with a third connection, which is used to feed back channel signals for a control center.
  • Such signals are used in television, radio broadcasting, text and image distribution Warning services of interest to subscriber signals, telemetry, surveillance, local programs, order service, information service, library service, interactive services, inventory management and remote data processing.
  • the invention has for its object to realize such a third connection using conventional antenna sockets.
  • this object is achieved according to the invention in that the through line output of the directional coupler is connected to the inputs of the bandpass filter and the bandstop filter and that the output of the coupling loop of the directional coupler is connected to the second connection.
  • the socket connected according to the invention represents a stub socket, via whose “outgoing” coaxial line additional signals can be fed in or taken out.
  • additional signals can be fed in or taken out.
  • carrier-frequency digital signals can be used for addressing subscribers.
  • the "outgoing" coaxial line then leads to a modem.
  • the frequency of the signals fed in can be below 40 MHz; the extracted signals can occupy the frequency band from 40 to 860 MHz.
  • the antenna socket according to the invention can also contain a corresponding crossover circuit instead of a directional coupler.
  • connection 4 now offers a connection option for devices for additional services which can emit signals both in the reverse direction and, if appropriate, also receive additional signals from the system distribution direction, such as, for example, carrier-frequency digital signals for subscriber addressing.
  • a connection can be made from port 4 to a modem which receives the carrier frequency additional signals in the downward direction, which can be transmitted, for example, in the frequency range 40 to 860 MHz, and feeds carrier-frequency additional return signals below 40 MHz into the system.
  • the broadband directional coupler 5 'offers the advantage of mutual decoupling of television (TV) or radio broadcasting devices connected to the coaxial sockets 2 and 3 and the device for additional services.
  • FIG. 5 shows an arrangement corresponding to the arrangement according to FIG. 4 with a transformer coupler 5 ".
  • a corresponding crossover circuit can also be used, depending on the frequency assignment.
