Definitions

  • the present invention relates to a switching device for a satellite reception system according to the generic term of Main claim.
  • Such devices are known as.
  • LNB Low Noise Block Converter
  • Satellite reception signals are used to optimize channel usage in two polarization planes (horizontal / vertical) and in two to be controlled separately Frequency bands before, so that, with every possible combination of these two parameters, each satellite typically can be received with four of these so-called IF levels.
  • IF levels IF levels
  • Multiswitch offers about eight input connections for connection of two satellite systems (e.g. Astra 1 and Hotbird in Germany) with four ZF levels each.
  • the means for selective high frequency connection of one of the plurality of input connections with the output connection in the frame Upstream of the invention configuration and storage means whereby this is configured via an interface and are programmable.
  • the configuration and Storage means provide a non-volatile Storage unit that permanently any of the Input connections (which is one of four possible IF levels an assigned satellite system) receives the Output port can be assigned in response to the associated selection control signal.
  • this programming is carried out by a commercially available PC or another, preferred portable programming unit, which then uses common Data buses, e.g. USB, with the device according to the invention or its configuration and storage means connected becomes.
  • a programming interface will then particularly preferably visual or graphic Have tools and control surfaces that it Allow operator (the configurator) in easier and clearly arranged for the system in question set the desired configuration and then - continue preferably - in a non-volatile memory unit of the System permanently.
  • the configuration according to the invention and storage means for each of the output ports prefers an individual configurability provide (however, realizations are also included uniform configuration conceivable and inexpensive). Especially are suitable for this purpose for each output connection provided configuration units that, ideally realized in the form of assignment tables, for each of those generated by an output user Selection control signals target the input required address and connect high frequency. It is also particularly preferred in this form of implementation as a multi-subscriber system if the user-specific provided allocation units, for example by means of a central data bus from a common, central one Storage unit, provided with configuration data can be.
  • a prerequisite for the proper implementation of this principle of invention is it typically about the Output connection brought in and from the connected Selection control signal generated, for example after the DISEqC protocol, from the (flowing into the receiver) High-frequency signal separated and then reliable data is interpreted so that the mentioned, according to training provided assignment unit reliably with control data can be provided.
  • a particularly preferred form of realization of the present Invention in terms of flexible and scalable Multi-user systems are located in the area provided for further training Modularization:
  • So-called basic module is provided, which is independently operational and receives all input connections (and to the expansion modules provided for further training loops) while only a limited number of output ports, typically 4, 6, 8 or none, is present in the basic module.
  • the basic module itself contains then in terms of data with each user-side output connection associated allocation units connected central Storage unit, as well as the (only) central Programming interface, so here, for example, at a more suitable central location within a larger house (or Residential complex or extensive distribution network), the common Setting and configuration can be done.
  • the extension modules that can be connected then enable the flexible assignment of further output connections, each, as described above, in the manner according to the invention through individual configuration selectively with the majority disconnected from input connections from the rigid limits of the conventional four IF level mapping scheme.
  • a non-volatile Storage unit is assigned, more preferably by a each assigned controller module controlled.
  • a complete or partial deactivation of an output connection is adjustable.
  • the present invention achieves that without receiver-side or other manipulative Interventions in extremely flexible and hardware-technically efficient Assignment of different satellite IF levels to the input connections of a multiswitch can; in particular it is achieved by the invention that the previous limit of "four input connections per satellite system" can be effectively broken.
  • a multiswitch 10 as a switching device has a plurality in the form of eight input connections 10 a to 10 h , to each of which a converter unit (LNB) of a satellite module can be connected at any high frequency.
  • LNB converter unit
  • SAT IF signals are present in the ranges 950 - 1,950 MHz or 1,100 to 2,150 MHz.
  • Each of the connections 10 is followed by a high-frequency amplifier 12, which is primarily intended to compensate for an attenuation caused by a downstream directional coupler field 14.
  • the directional couplers 14 provide the RF signal present on the input connections 10 a to 10 h to an RF changeover switch (selection switch) 16, via which the signal from one of the eight lines is then selectively selected and an output connection 18 for connection to an otherwise known, external satellite receiver is provided.
  • the multiswitch unit 10 duplicates the chain of directional couplers 14, selection switches 16 and output connection 18 for a second output connection 20 with a corresponding connection of directional couplers 22 and changeover switch 24 provided in parallel.
  • the device according to the invention has the Possibility of flexibly assigning input connections (and corresponding RF signals) to the output side Assign input selection control signals:
  • About the output connections 18 and 20 are one of a connected Selection control signal (not shown) generated by the receiver, usually a DISEqC control signal.
  • a low-frequency signal is generated by means of a Low pass 30 shown schematically from the to the selection unit 16 or 24 running high-frequency line decoupled and using a separate one for each output channel the provided decoding unit 32 is detected and interpreted, namely with regard to the necessary switching criteria.
  • This signal is a downstream allocation unit 34 ("mapping table") with the aim of from this table one belonging to the decoded switching criterion Switch configuration of the selection switches 16 or 24 to generate, hence the associated input connection to contact at high frequency.
  • the unit 10 which is designed as a basic unit or basic module, with an expansion module 50, which is looped through the eight input connections 10 a ... 10 h in parallel (and in turn is looped through to possible, subsequent further expansion modules).
  • the expansion module forms space for one or more output channels for an output connection 52;
  • an arrangement of directional couplers 54, changeover switches 56, low pass 30 for the selection control signal, decoding unit 32 and assignment unit 34 is again provided.
  • the radio frequency signal of the respectively selected input line to the output connection 52 then flows again, depending on the switch position of the unit 56.
  • the data bus 36 for the assignment unit (mapping table) 34 is looped through further.
  • the person responsible for the configuration now has the option of connecting several satellite units, in particular more than two, to the eight input connections 10 a to 10 h ; in particular, fewer than four IF levels can be connected and freely configured per satellite unit.
  • This is done by means of a visual and graphical user interface of a PC connected to the connection 42, shown as an example in FIG. 2; the associated configuration data are stored in the unit 38 and then individually made available to the mapping tables 34 via the data bus 36.
  • this makes it possible for each of the receivers connected to the output connections 18, 20, 52 to be able to selectively access the input connections simultaneously and freely configured in accordance with the respective mapping table, or else a common central configuration takes place.
  • the eight input connections are each fully occupied with active satellite IF levels.
