Description

State of the art

The The invention relates primarily to a satellite receiving and Home distribution system with wireless and wired transmission links and feeding several transponders (protection claim 1).

For the reception Of TV programs, there are basically three options today either the direct reception over the satellite antenna (parabolic antenna, this would be the actual satellite TV), terrestrial or over the cable television.

• 1. lässt sich das System mühelos mit einer einzigen Antenne empfangen, und
• 2. gelingt es mit dieser Anordnung, alle ausgestrahlten Kanäle_{[bku 1]} der Astra-Satelliten, welche mit insgesamt 64 Transponder (Sende-/Empfangseinheit) ausgestattet sind und im sogenannten unteren Frequenzband (10,70 bis 11,70 Gigahertz) arbeiten – auf einmal zu empfangen.

For this purpose, ground stations first transmit relatively large parabolic antennas in the signals transcoded television broadcasts to the satellite (so-called uplink), the frequency range is between ten and 13 gigahertz. The signals are received by the satellite in a receiving unit and forwarded to the transmitting unit (transponder uplink) of the satellite. Typical television satellites, e.g. Astra satellites are capable of receiving and transmitting at least 16 TV programs and the associated sound. To make better use of the available frequency range, the satellites emit radiation at various levels. Common here are the emissions on a horizontal and a vertical plane and the division into a lower frequency band L of 10.7 to 11.7 GHz and an upper frequency band H of 11.7 to 12.75 GHz. The individual Astra satellites are only a few kilometers apart (about 140 kilometers) from each other. Due to the long distance to the earth (36,000 kilometers), the distance between the satellites "shrinks" to practically one point - this is located at the position 19.2 ° East, which has two main advantages:

• 1. the system can be easily received with a single antenna, and
• 2. succeeds with this arrangement, all the broadcast channels _{[bku 1] of} the Astra satellites, which are equipped with a total of 64 transponders (transmitting / receiving unit) and in the so-called lower frequency band (10.70 to 11.70 gigahertz) work - to receive at once.

For the transmission digital services (eg digital television, digital radio) other satellites also on the position of the other Astra units positioned. The satellites Astra 1E to 1G work in the upper Frequency band (11.70 to 12.75 gigahertz) and are total with 56 transponders equipped. With the help of digital technology (data reduction) is always a transponder The satellite Astra 1E to 1G is able to transmit up to ten digital TV channels (instead of an analog TV channel). In this way, the transfer succeeds of several hundred digital TV channels.

About the Transponders send the signals to the receiving stations on the Earth sent (so-called downlink, Ku band: 10.700 MHz to 12.750 MHz). In cable television, these are large ground stations that come with connected to the cable network and the corresponding shipments in feed this network. For direct reception, also direct-to-home satellite broadcasting (DTH), are the respective private households with satellite reception system to small ground stations. The reception system consists essentially from a parabolic antenna ("satellite dish") and a satellite receiver (the receiver). It uses a transmitting and receiving technology on the Base of polarized waves (waves only propagate in one particular Direction (oscillation plane) off). The converter, which also as LNB (Low Noise Block) or LNC (Low Noise Converter) is called, reinforced and converts the satellite signals from the high frequency range in a lower intermediate frequency range from the high frequency range in a lower intermediate frequency range from 950 to 2150 MHz.

From the EP 1 177 647 A2 For example, the DTH concept is known with a transparent embodiment of satellite television in which, in a ground station, the correspondingly transmitted broadcasts are transmitted wirelessly to the private households. For this purpose, special converters are required both in the ground station as well as in the private households, the individual participants via a reverse control channel independently of each other, the various outputs of the converter control or select the different levels of reception.

Furthermore, the concerns EP 1 602 237 A1 a hybrid system of cable television and connection of other participants to a central office via a wireless network. In a further embodiment, it is provided that instead of the wireless network, the connection via Ethernet or the PC or HiperLAN2 is performed in MPEG-2 format. The billing of the participants via a return channel to the center, such as a telephone connection.

If several subscribers, ie several receivers, are to be connected to a satellite antenna or to the converter, then a special converter for the simultaneous reception of several receiving levels is necessary. So that the individual participants can independently control the different outputs of the converter or select the different reception levels In satellite reception systems, a switching device - a so-called "multiswitch" or "multiswitch" or a "branching device" - is provided, which serves as a connection node Each subscriber can then select by switching between one of the four reception levels mentioned above takes place in that the subscriber (receiver) a switching voltage (14V / 18V), a switching frequency (low-frequency tone signal, usually 22 kHz) or a serial control code (eg DiSEqC data telegram, "DiSEqC" = Digital Satellite Equipment Control, which uses a modulated 22 kHz signal) is given to the multi-switch. A switch matrix formed in the multiswitch connects the respective subscriber in accordance with the pending control signal to the corresponding input of the multiswitch.

In practice, an increasing complexity of satellite reception systems, in particular community systems (sluice gate, multi-switch), introduction of digital radio and TV receivers and new services such as the Internet, combination devices such as multimedia PC, automatic turning systems, among others, and associated digital remote control concepts to watch. To cope with this increasing complexity, twin converter arrangements have long been known by which subscribers can independently receive programs broadcast over one or the other polarization in a lower or upper frequency band. From the EP 1 217 836 A2 For example, a twin-converter arrangement is known which is designed so that it can also serve as part of a multifeed arrangement for receiving programs broadcast via a further satellite position. Typically this is done by means of a single satellite dish, when two satellite positions are arranged in a close orbital position to each other geo-stationary, so that with a "squinting" multifeed arrangement, the programs broadcast by both geostationary satellites can be received. To implement this concept, the twin converter arrangement has at least one further connection, namely an additional input, which is designed as a loop-through input. This loop-through input allows an assigned, connected subscriber to receive the programs broadcast via another satellite position. In this case, the actual output, to which an associated subscriber can be connected, can be switched as required between the actual output of the twin converter arrangement (twin LNBs) for receiving the programs broadcast via a first satellite position and the loop-through input. In a preferred embodiment, a crosswise interconnection of the two twin converter arrangements is made, wherein each of the two twin receivers has a corresponding additional loop-through input. In such a multi-feed arrangement, only one subscriber is connected to the two twin converter arrangements, with the respective output for the second subscriber being connected to the loop-through input of the respective further twin converter arrangement. Thus, both subscribers may receive the programs broadcast from both satellite positions, optionally in a lower or upper frequency band in both polarizations. Since, from the perspective of the respective subscriber, the programs received from a first and second satellite position are received at different setting positions, it is preferably provided that the twin converter arrangement has, in addition to the two outputs and the additional loop-through input, a further coding input which does not contain any RF signals supplies and so far "passive" is switched. Due to the coding device effected thereby, however, the position value of an LNB branch can be changed from the default setting "Default A" to "Default B". The second LNB branch thus contains a corresponding assignment of the respective other satellite position. Thus, after the corresponding coding has been activated for a subscriber, this leads to the fact that both participants via the apparently same twin converter, for example via the first twin converter for the satellite position X and the second twin converter for the further satellite position Y, receive the broadcast programs.

In further education this is from the WO 03/094397 A1 or the corresponding thereto EP 1 502 371 A1 a method and a device for generating at least one transponder in the satellite intermediate frequency plane known. In order to realize a one-cable structure, in a first embodiment, a first implementation of the lower satellite frequency band with a local oscillator of z. B. 9,600 MHz and a first implementation of the upper satellite frequency band with a local oscillator of z. B. 13,850 MHz proposed. Because of these other local oscillator frequencies than the prior art, it is possible for the lower limit of the lower band to coincide with the lower limit for the upper band of 1100 MHz. For the second mixer is not a local oscillator frequency of, for example, 10600 MHz is used, but in contrast a local oscillator frequency, which is above the upper end of the upper frequency band. In this case, an inverse conversion is carried out in such a way that the frequency range lying above the upper limit of the upper frequency band (ie above 12.750 MHz) is converted into a range below 1100 MHz, which otherwise results from transponders and satellite signals lig is free. As a result, by simply implementing the mixer using only one tunable oscillator (for example, 2025 to 3100 MHz) and only a subsequent selection of a suitable bandpass filter (eg, 950 MHz center frequency and a bandwidth of 40 MHz), a freely selectable transponder, for example be implemented with a Sat.-ZF1 / Sat.-ZF1 center frequency of 950 MHz. For example, a so-called one-cable tripple converter solution can be realized in which two offset transponder frequency ranges are combined with a satellite IF band range. Or it can also be a single-cable quad LNB solution are constructed in which a plurality of frequency spaced apart transponder are generated, and these transponder branches are then combined at the respective output of a switching matrix arrangement via a crossover. As a result, several transponders can be fed to a single common antenna line.

Furthermore, from the DE 44 07 831 C2 discloses a method for accessing passive broadband coaxial cable networks with M subscribers connected to network nodes providing uplink and downlink N transmission channels, where M> N, where an uplink (backchannel) frequency band and a downstream band of frequency band the same coaxial cable are provided, and wherein the participants each have a receiver and a transmitter. The method is used for bidirectional operation on a coaxial cable with a tree or ring structure, in which the participants can communicate with each other via a network node or via other network nodes connected to these participants or in the network node available retrieval services. Specifically, it is provided that the receiver of a subscriber in its attempt to access the frequency band of the upward direction is searched for a free carrier frequency channel that this is then occupied by turning on the subscriber's transmitter and thus the network node is signaled the connection request and that of this then a transmission channel allocated in the downlink direction. It is assumed that in view of the expected traffic statistics never all participants at the same time want access to the system, so that a larger number M of subscribers than the number N of the available channels at any time access is made possible. The receivers of all subscribers can be tuned to the carrier frequencies of all channels in the up and down direction. In the same way, the transmitters of all subscribers can be tuned to the carrier frequencies of all channels in the upward direction (return channel). In the network node, the number of transmitters and receivers is equal to the number of channels N available in the system. By switching on the carrier and transmitting corresponding signaling information, the network node notifies the newly connected subscriber a transmission channel in the downward direction. The bidirectional communication, which can be both symmetric and asymmetric, with other participants connected to the network nodes, with participants that are connected to other network nodes, or z. B. databases of polling services available in the network node can begin.

Furthermore, from the DE 197 49 120 C2 a satellite receiving system or an associated method for their operation known in the or in which a single antenna line z. B. four or eight participants are connected, without causing problems in terms of data transmission and control of participants and assignment of specific addresses. For this purpose, a converter block is provided in the head station, in which a separate converter stage is provided for each connected subscriber. There, each satellite program selected by each individual subscriber, ie the corresponding satellite program channel frequency is converted into different channel frequencies with sufficient frequency spacing and fed via a sum circuit with a common receiver bus leading to all participants, ie an antenna derivation. Specifically, in the respective converter stage, conversion takes place into a frequency channel assigned to a single subscriber and thus receiver, which lies in the region of the received satellite frequency level, so that conventional receivers can be connected on the subscriber side in principle. The connected receivers work together with a controller unit in such a way that the converter stage assigned to this receiver is controlled by means of a corresponding receiver signal such that the selected program at the corresponding output of this converter stage of the converter block is converted to a preset frequency channel and fed into the sole antenna line becomes. The data bus for controlling the connected subscribers / receivers in interaction with the controller unit can be referred to as a multimaster bus, since the connected subscribers are not operated in a master-slave configuration but are in principle connected to this multimaster bus on an equal basis are. Via this multimaster bus, it is then possible to assign each receiver a specific address in the converter stage from the controller so that a program selected by the subscriber is converted to a different channel, ie a different channel frequency, via the converter stage assigned to the respective receiver all connected subscribers / receivers via the The channel assigned to them can select and receive all programs which can basically be received by the satellite receiving antenna. The converter block is preceded by a matrix that allows the individual subscribers, ie the connected receiver, independently of each other, to select and receive any program, regardless of whether it is transmitted with vertical or horizontal polarization in a lower or upper frequency band. The matrix arrangement can be designed such that control can be effected by switching from 14 V / 18 V and / or from 0 KHz / 22 KHz or by means of DiSEqC. In order to carry out the corresponding control in the matrix arrangement, each converter stage comprises a voltage switch and a downstream 22 KHz modulator. Furthermore, each converter stage in the receive direction following parallel to the switching branch comprises a capacitor for galvanic isolation, a first mixer, a downstream amplifier, a further downstream SAW filter and a further mixer connected on the output side. While the first mixer via a voltage controlled oscillator having a selectable oscillation frequency varies about operable, the oscillator frequency of the second mixer is driven for example by a fixed local oscillator frequency f ₁ to f _n of an associated local oscillator. The connected receivers work together for multimaster communication with a controller unit so that each receiver can only send and receive control signals if no other receiver is activated or the controller does not send any signals to the bus. For this purpose, measures for collision protection (bus observation phases, address and various collision protection headers) are provided, which ensures that at any given time only one receiver on the bus can be active, ie send out data or receive from the controller. For this purpose, the multimaster bus is operated by means of a DC level switching so that it is always recognizable whether the multimaster bus for transmitting new transmission signals by another receiver is ready or disabled. As soon as a receiver emits or receives transmission signals to and from the controller stations, the multimaster bus, referred to above, preferably has its status "disabled" so that other receivers can not enter into communication with the controller. The transmission protocol is structured in such a way that if two or three receivers are operated at the same time, they should check after a different set time whether another receiver is still in the "communication stage". If this is detected, the respective receiver that recognizes this, returns to its original position and must wait for another waiting cycle. In this way, it can be ensured that only one receiver ever controls a converter stage at a time, the subscriber channel (frequency channel) being presupposed as the default.

Especially for larger antenna systems that have a great many antenna doses and / or multiple trunk lines, and in which more than one participant is connected per trunk, stands by the measure until the commissioning of a subscriber to assign this a frequency converter (multiple converter) with the appropriate output frequency , a cost effective solution available. Due to the dynamic allocation, n subscribers will be used only m multiple transformers (m <= n) are required, since in a typical building installation with n antenna doses and m residents, usually the highest m subscriber connections are simultaneously in operation. Since the cost of such a system with frequency converters is determined primarily by the frequency converter with the associated filters, the saving of frequency converters means a massive cost savings, especially in installations with m << n. Due to the central assignment of the occupancy can be surprisingly simple and cost-effective way an access conflict can be avoided.

The above-described embodiments of the device according to the DE 10 2005 040 012.4-35 The applicant has the advantage that in larger buildings, the construction of satellite distribution systems without restrictions as in known "Einkabellösungen", especially that only a certain section of the entire range of programs is available, is possible. In particular for the installer, this device according to the DE 10 2005 040 012.4-35 Considerable simplifications, since the extension to a new participant in a tree structure not automatically as in the prior art, the laying of a new antenna cable (star structure) means. Furthermore, this device according to the DE 10 2005 040 012.4-35 can be used independently of the structural conditions and allows the flexible assignment and controlled implementation of transponders for the subscriber provision via a ZF channel permanently assigned to the subscriber.

As the above appreciation of the state of the art shows, differently configured configurable multiswitches or multifeed satellite reception systems with switching matrixes and transponder branches and "single cable solutions" with or without the possibility of subsequent extensions with regard to the connectable subscribers are known. In general, the cost of such systems with frequency converters are determined primarily by the frequency converter with the associated filters. The same applies to the flexible allocation and controlled implementation of transponders according to the various embodiments of the device according to the DE 10 2005 040 012.4-35 the applicant in order to allow subsequent extension. There are also known methods with which data rates of 54 Mbit / s and more can be transmitted over a radio link, z. For example, the WLAN standards IEEE 802.11 (b, g and more recently n). But for no current standard there is enough bandwidth to transmit all the transponders of a satellite simultaneously. According to a selection of the transponder to be transmitted must be made in a radio transmission and lack in practice cost-effective methods or devices in which - even in retrofitted Er extensions - the entire frequency spectrum is recorded and therefore there are no restrictions with regard to the range of programs available. This is particularly important because consumer electronics, especially the satellite receiver manufacturing industry, has for many years been considered a highly advanced, adventurous industry that is quick to pick up on improvements and simplifications and put them into action.

problem

Of the Innovation lies opposite the object of the known methods or devices, to develop these so that for channels with limited bandwidth a transponder selection is made that is in the market satellite receivers is compatible.
