A corresponding method and a corresponding device are from the US patent 4,893,240 known.

Another, similar method and a corresponding device with the essential Recipients carrying out process steps are already known from German patent application no. 37 41 324.4 known. This known device and the corresponding method are used all for remote control of garage doors. This is in the sense of the present application Opening and closing a garage door as a single one, from a corresponding recipient Function to be triggered considered.

The system known from US-A-4,893,240 consists of a transmitter and one Receiver for remote control of a machine. In a remote control transmitter can from a code can be entered for a user and when a key is pressed or Key combination on an operating unit of the remote control transmitter is shared with a coded signal that determines a function to be triggered on the machine, at the same time the user's personal code is transmitted and it can be done in this way his access authorization to the machine is checked and ensured. It is However, it is essential that the same keys are always used to trigger certain functions or key combinations are retained so that there is no incorrect operation of the machine can come.

Other, conventional methods and devices, for example from EP-A-0.319.781, EP-A-0.037.238 and DE-33 32 667 A1 are essentially restricted to by actuating a transmitter to the receiver and the units connected to it activate, this activation process then depending on the prevailing state Example triggers an opening or closing of the garage door or another function. The coding makes sense, the activation of the receiver only then trigger when a specific, evenly coded, Pulse train was received. There is a code on the receiver of these known systems adjustable, which exactly corresponds to the code of one or more specific transmitters, so that the desired function of opening or closing a garage door or the like is only triggered if the receiver had received a pulse train, that corresponded exactly to the set code. This is to prevent the function the opening or closing of a garage door is triggered, for example, in the Another station is operating on the same frequency, but not in the neighborhood sends the coded pulse train and z. B. to operate another garage door is operated. The signal emanating from the transmitter is used for unambiguous signal recognition and a pulse train received by an RF receiver, preferably with a demodulator Gain control, which converts the pulse train into a digital signal, i.e. typically in a sequence of voltage values at two different levels, to which you can assign a logical "0" or "1".

In one of the known systems, several different ones could already be used in the receiver Codes are saved so that it was possible to use the intended function accordingly different, but each having one of the stored codes trigger. In this way you could, for example, achieve that a gate entrance for a large number of different users have been made available, their transmitters each one had different codes, but all of these codes in which the operation of the Tores triggering receivers were stored while at more distant garage doors additional receivers could be arranged, each only a part or a part of the Had stored station codes and therefore only by a few or a specific station were to be operated. However, this system has the disadvantage that even if a For example, users only use a specific garage door using the remote control wanted to actuate, the corresponding transmission impulse under certain circumstances also from the Receivers installed at the gate entrance were received and accepted, so unintentionally the corresponding gate entrance was also opened. This could only be avoided if the different receivers at the gate entrance or garage very far apart were, so that the range of the corresponding transmitter is already at half the distance was significantly exceeded between the receivers, or by the mentioned gate receiver For example, it was set to be very insensitive, but this was the case with unfavorable spatial conditions Conditions or due to shielding by car bodies, that an authorized user standing in front of the gate with his transmitter the could not operate the relevant gate if the level of the transmission pulses below the high set sensitivity limit of the receiver.

Another limitation of some known, relevant systems commonly used for the Remote control of garage doors or gate entrances is that they are in the essentially only have a single output, that after receiving a transmission pulse is either active or not. So it is not possible to use different ones independently Trigger functions. For example, the output of the receiver in addition to the connection to the door operator, for example with a switching relay for one Lighting are connected, however, this means that then in any case at the Actuation of the door operator also switches on the lighting, regardless of whether this is necessary or desired in the respective situation or not. At most one automatic switching to reverse to the other process, depending on whether an opening or closing process was previously completed, and in this respect possibly also a second exit was with the methods and devices according to the prior art possible. In the sense of the present invention, however, this only corresponds to the control a single function.

Everyday use are infrared or ultrasonic remote control devices for Known televisions, VCRs and stereos. Although they are able triggering various functions, however, are not codable and for certain users have the particular disadvantage that they are generally only in line of sight between the transmitter and receivers can work because of infrared and ultrasonic waves walls or other obstacles not penetrate, unlike the radio frequency waves with which the coded remote control systems are usually operated according to the present invention.

Compared to this prior art, the present invention is based on the object To create a method and an apparatus with the features mentioned above, which the Codability and ability to work without line of sight between transmitter and receiver with Greater design options and freedom when using different functions link.

With regard to the method, this object is achieved in that one is free on the receiver side Selectable assignment of functions to be triggered to the stored code words.

In other words, the data word sent can be understood as a code word in which in principle, any sections or areas are reserved for additional information. On the receiver side this data word is compared with a stored data word, whereby now but a certain function to be triggered is assigned to this stored data word while different data words at the same time are absolutely the same Functions to be triggered can be assigned if they are in the information section of the code word, that is, the area for the additional information mentioned reserved, match. The term "function to be triggered" is very extensive understand. For example, two functions to be triggered are considered different, if different outputs of the receiver are controlled. One can possibly also functions to be triggered as in the sense just described view differently if one and the same exit each with a different Time behavior, for example delayed, "flashing", as a string contact, as an impulse or in another Shape is driven. Such differences in the functions to be triggered can but can also be triggered in a controlled manner in that the data words sent are in their Distinguish code part, while the part reserved for the mentioned information is the same remains. This could, for example, be used by different users with their transmitter on the receiver control the same output, but this would then possibly be a different one Show time behavior. Ultimately, the entire data word sent is logically called "code" processed, but in the narrower sense under the term "code" that part of the sent and received data word would look at the same transmitter always remains unchanged while different stations are in these code sections fundamentally differentiate (insofar as this corresponds to the length of the code portion and the number of the total transmitters manufactured is possible). In contrast, the for the additional information or a function to be triggered reserves the same proportion of the data word for different transmitters, if it is to trigger the same function, that is, if for example the same channel should be controlled. However, the method according to the invention offers the freedom, too to use the pure code portion as additional information for the function to be triggered Example with regard to the time behavior already mentioned, since the entire sent and identically stored data word logically a certain function including the Time behavior is assigned.

The method according to the invention has a whole range compared to conventional methods essential advantages. For one thing, the receiver can now perform completely different functions trigger independently of each other, such as switching on a light as mentioned and the operation of a garage door. Likewise, the recipient could have two or more Open and close different gates arranged side by side or one behind the other independently of one another, so that it would be possible, for example, for a user to have access admit only to one of the gates or to a certain group of gates while others Users in turn have different access rights. This is possible because of the transmitter now, in addition to the code word, information about the one to be triggered Function is sent out, while the receiver not only compares whether the relevant Code word is stored and thus the basic access authorization of the user displays, but also checks whether this code word also in connection with a certain function to be triggered is stored, since only then the authorization for the This particular function is triggered.

There are basically different ways to ensure this way of working. It would be possible, for example, to assign different memory locations to the code words, each after whether and which functions or groups of functions should be triggered, if the relevant code word is received together with the corresponding function order. However, an embodiment of the method is preferred in which the triggering of the Function assigned to code regardless of the memory location of the data words, i.e. the code words and the related information. This can be achieved, for example, in that together with data about the function to be triggered, the respective code word in one single data block or a data word is stored, which leads to the fact that Code word portion of the transmitter may be stored several times if with the relevant, the code having transmitter several different functions can be triggered should, so that in the receiver for each information unit characterizing the function concerned the information units defining the code word are also stored.

The method according to the invention can be used meaningfully even if only a single function is to be triggered, for example in the case of closely spaced one Receivers that are to be operated independently of one another by the same transmitter (in this In this case, the information unit about the function to be triggered can be seen as an extension of the Code)), however, an embodiment of the method is preferred, in which the relevant receiver at least two different functions can be triggered.

A variant of the method according to the invention provides that the receiver emitted data word, at least as far as it contains the code word portion and the information data includes information to be triggered, possibly including its timing, is interpreted and treated as a code word on the receiver side overall, whereby on the receiver side in addition to this extended code word, the information data for the function to be triggered and their time behavior are saved. In this case you do not need a specific, in Sender and receiver identical assignment of information bits to certain to be triggered Functions.

It is understood that the number of different functions to be triggered is in principle not is limited and depends only on the practical circumstances and requirements. According to one embodiment of the invention, there are, for example, eight different outputs provided on a receiver according to the invention. Again in connection with garage facilities these functions could, for example, trigger different aggregates consist of 1. a common gate entrance, 2. path lighting, 3. a garage door, 4. the garage lighting, 5. a lifting platform in a double parker, 6. a lock actuation for an access door between the garage and a staircase, 7. a staircase lighting. It would also be possible to use all of these functions simultaneously or immediately one after the other triggered by a single button press if the transmitter is set up accordingly. In such a case, an embodiment of the method according to the invention is special preferred, in which the individual functions can be triggered with a time delay, wherein these time delays are preferably also individually adjustable. The aforementioned Functions can then be triggered in reasonable increments, so that for example, the last-mentioned function "switching on the staircase light" only triggered is when the user enters the driveway with his vehicle, possibly also in the garage has broken in and is just getting out of his vehicle. At this point in time For example, the closing of the entrance gate should have been completed long ago.

It is also useful if when comparing the stored data words with the received data words at least the information about the function to be triggered in parallel read from the relevant memory and with the corresponding data of the received Data word are compared. Depending on the width of a corresponding bus system of course, the entire stored data word including code in parallel read out and compared with the received data word.

Furthermore, it is expedient if the data word in question in addition to the information about the Function to be triggered additionally the information about the size of a certain Contains the time delay with which the function is to be triggered, if not generally one assigned a certain function, but a changeable time delay becomes.

It is for the comparison of the sent data words with the stored data words of course, useful if the information about the code word to be triggered Function and possibly also the time delay at predetermined positions in the Data word can be found.

According to the invention it is provided that the serving as a basis for comparison in which data words stored in the respective receiver are thereby stored or in the memory be entered that the receiver is switched into a so-called "learning state" and that the transmitter is then operated according to the desired function, wherein the transmitter sends out a pulse train which corresponds to a data word which results from the Codeword, information about the function to be triggered and possibly also information contains a corresponding time delay. It is particularly useful if the Sensitivity of the receiver system in the learning mode considerably, preferably at least is reduced by 10 dB. This means that the transmitter in question is very close to the Recipient must bring this so that the code sent out including the rest Receives and stores information while happening simultaneously from others nearby transmitters located outgoing transmission pulses due to the very low set Sensitivity of the receiver can not be detected and registered by this. In this way it ensures that only the code and the associated functional information is actually of the sender are transferred to the memory of the receiver, which specifically for this purpose is brought very close to the receiver.

An embodiment of the method according to the invention in which the internal clock frequency for reading and comparing the received and stored Data words at least one order of magnitude below the transmission frequency of the associated FH system lies. In other words, the internal clock frequency of the evaluation logic of the system is at most 1/10 of the transmission and reception frequency of the transmitter and receiver. Is preferred an even greater distance, for example, in which the internal clock frequency for the Data comparison below 1 MHz, better still below 100 kHz and in the preferred embodiment Is 32 kHz, while the transmission frequency is above 10 MHz, preferably at 27 or 40 MHz is. In the preferred embodiment, the frequencies in question are therefore approx. three orders of magnitude (a factor of 1000) apart, so that mutual interference by Crosstalk between the transmission frequency and the clock frequency are practically excluded. This contributes to a considerable increase in functional reliability. Still it works The inventive method extremely fast and by no means slower than conventional Procedure when the individual bits or information units of the data words each read out in parallel from the data memory and compared with the received data. With a clock frequency of 32 kHz and a complete parallel reading of the entire Data word including code information and information about the function to be triggered or Time delay could therefore be 32 complete data words within a thousandth of a second compared and corresponding functions are triggered. Even if for security reasons only the receipt of a complete data word, including one each, two or three times independent comparison is the triggering criterion for the desired function, in this case, around ten different ones could still occur within a thousandth of a second Function can be detected and triggered, for example, when pressing a corresponding Button the transmitter as a result of such a series requests ten different functions. The relatively low clock frequency is therefore none for the intended functional purpose Adversely, however, as already mentioned, the functional reliability is thereby considerable is improved.

With regard to the device mentioned at the outset, the object on which the invention is based becomes solved in that the control logic has a structure or has a programming which the freely selectable assignment of stored code words that contain at least one piece of information included via a function to be triggered, permitted to each of the outputs, and compares the received remote control signals with the stored code words.

However, it goes without saying that the assignment of a specific code word to a specific one Output from the additional information stored together with the code word the function to be triggered depends. The arbitrary assignment between any code words and any outputs are only available in the sense that the relevant code word can be saved together with any desired function, but this does not mean that each Code word must actually be saved together with all functions.

In the preferred embodiment of the invention, memory management is parallel Access to at least the data units of a data word indicating the function to be triggered, The data words are preferably accessed in parallel over the entire word width.

An embodiment of the invention is particularly preferred in which at least the decoder, the memory and the control logic on a common semiconductor circuit or chip are accommodated. In this case, the control logic can access the memory in parallel easily integrate into the system and the decoding of the received data words, their Evaluation and triggering the associated function can be done very quickly within a few Cycles of an associated clock generator take place. As already in connection with the preferred Embodiment of the method mentioned, a clock generator is provided, the frequency is at least one order of magnitude smaller than the transmission frequency, the clock frequency is preferably 42 kHz, while the transmission frequency is at least 27 MHz.

Furthermore, in the sense of the preferred method design for the device Embodiment preferred, in which one between the control logic and the outputs Time delay element is switched, for which the time delay is preferably adjustable. The control logic can, for example, consist of a stored data word that is associated with a sent data word matches in terms of code and function specification, information take the amount of the desired time delay and the subsequent time delay element set in the desired way so that the relevant output only after a corresponding time delay, measured from the time of the positive data comparison on, is triggered. Optionally, the data word sent can also be a corresponding one Contain time delay information, this also optionally in the data word comparison included or without comparison to the control logic and the time delay unit can be passed.

In the preferred embodiment of the invention, the memory has a minimum size of 30 data words, each with a word length of at least about 60 bits, which one The total amount of memory corresponds to approximately 1800 bits. Given the ongoing downsizing of semiconductor structures can, however, on a chip with all of the above, essential functional units also significantly larger memory with the ten or Can accommodate hundreds of times the amount of data.

A word length of approx. 60 bits has proven to be completely sufficient to be sufficient long code word on the order of 20 to 24 bits, 8 bits of information about the Function to be triggered, 8 bit information about a possible time delay or also Activity duration of an output and other bits, for example check and test bits, bits for marking the end of a word and the beginning of a word etc.

Further advantages, features and possible uses of the present invention will become apparent clear from the following description of a preferred embodiment using the only associated figure.

The figure is a schematic representation of the receiver according to the invention with its Periphery, but without a high-frequency receiver and without being connected to the outputs Aggregates.

One can see in the center of the figure one indicated by a dashed frame Integrated semiconductor circuit or chip 100, the on the dashed circumference of the The squares shown in chips 100 schematically represent the contacts of chip 100. The of outgoing signals are transmitted by means of an antenna and a subsequent one High-frequency parts, which are not shown, received, amplified and sent to the demodulator 10 passed on. The received pulse train is demodulated in the demodulator 10 and thus in converted, for example, a 60 bit long digital data word. The demodulator 10 gives this signal on the input 12 of the chip 100 on. A control output 11 of the chip is connected to a control input of the demodulator in order for a programming or Lemgangs reduce the sensitivity of the demodulator, so that in this mode only nor the signals to be learned or stored in the immediate vicinity of the receiver brought transmitter can be received to disturbances and incorrect storage to exclude.

The function of a number of elements of the chip 100 and the periphery should first be explained a simple example in normal operation of the receiver will be explained. Subsequently the remaining parts of Figure 1 are explained with their special functions and variants. To the serial input 12 connects a complex integration filter 101, which functions as a Signalformers has, which compensates for the width fluctuations of the individual bits and also the signal level, if necessary, be leveled again. At 112 are a flat rate internal data lines of chip 110 denote both serial and parallel Bus lines can be. Block 107 schematically designates a comparator; the block 102 a memory, in the example shown with a memory volume of 6 KB, with 103 an address management for the memory is designated and with 108 an evaluation logic. The converted by the input filter 101 into a sequence of uniform, digital data bits The pulse train is first checked to see whether it represents a valid data word at all, e.g. with a length of 60 bits and special bit sequences, e.g. Beginning and end of word characterize, whereby a check of so-called check and check bits also takes place, whereby any faults in the transmission of the data are recognized and faulty data words are eliminated should be.

The comparison then takes place with the data words stored in the memory 102. If a valid data word was found, i.e. is a match of the sent Data word with one of the stored data words has been determined, it is checked whether this word already immediately before or within a predeterminable, previous one Time interval has already been received once. The frequency of the Receiving a specific, valid data word either in succession or alternatively registered within a predeterminable time interval. After this counter a predeterminable Has reached or exceeded the limit, the command to trigger the function, which is according to an information contained in the data word to be triggered is considered valid and it will a corresponding trigger command is initially passed on to the timer 109. The timer 109 has eight different outputs, labeled 80 to 87, with each of the outputs 80 to 87, a time delay element is connected upstream of the timer 109. It can a certain fixed time delay can be assigned to each of the outputs 80 to 87, if necessary, however, the information about a specific setting of a particular one can also be given Delay element from the stored or received data word to the timer are passed on, which is then a corresponding one for the respective time delay element Value. The delays are preferably set in steps and in digital form Form, with the individual outputs 80 to 87 different maximum delay ranges can be assigned. The time delay for opening one, for example Outside gates, in front of which e.g. a vehicle at the moment of sending an opening command can be set to zero and the associated output channel 80 either requires no delay element at all or one that has maximum time delays in Range within a few seconds. In contrast, other time delay elements can be used for others Outputs e.g. gradually in the range from a few seconds to minutes or even Hours can be set.

The timer 109 and its time delay elements and outputs can also be used optionally be designed so that the associated output is not only one Activate certain, delayed point in time, but also so that this Activation during a predefinable time interval or until a trigger is triggered Stop command remains active. It is also possible to use individual channels of the timer to design that after receiving a valid trigger command the associated output is activated intermittently, which for example when the lamp is connected, a blinking of the Lamp would cause. Finally, evaluation logic and timers can also be designed in this way be that a certain output during a certain, preferably small time interval beyond the receipt of the last valid data word with the relevant function selection remains active. This means that, apart from a small time delay, this corresponds to the mentioned interval, an output remains active as long as the transmitter has the relevant data word sends out (so-called strike contact).

The so-called programming mode is considered below. The programming mode serves to enter certain data words in the memory 102, so that later when a such a data word, a specific function which is also desired in this data word optionally with an additional desired time delay or a largely arbitrary one Predefinable time behavior (flashing, activation duration) is triggered. The switch 40 is made from two pushbutton contacts 41 and 42. A short actuation of the contact 42 leads to switching in programming mode, i.e. the output 11 is activated and the demodulator thereby in reduced its sensitivity. At the same time, the output 80 of the timer is first 109 selected or addressed. A further actuation of the push button switch 42 switches on the following output 81 etc., until after a cyclical run through the outputs 80 to 87 a further actuation of the push button switch 42 selects the output 80 again.

After a certain output of the outputs 80 to 87 has been selected by correspondingly pressing the push button switch 42, the push button 41 is used to select a specific function. The function selection is shown in Table 1 below.

The selected output and then also the function can use the two-digit number LED display 50 can be read. Is a function with a for a selected output certain time behavior has been selected, then can at the BCD input 20 via a specific switch combination of the four BCD switches between 16 different time ranges to get voted.

All this information about the selected channel, the selected function with your Time behavior and the time range are saved together with a code word, which is then via the demodulator with its reduced sensitivity has been received. To do this, the appropriate transmitter that has a specific code transmits, operated in the immediate vicinity of the recipient. As soon as the control logic 108 is one has registered receipt of the same data word at the input 12 at least twice, that is relevant code word together with the information set at inputs 43 and 44 including the time frame information from the BCD switch 20 in a 60 bit Data word stored in the memory 102. Previously, the entire RAM 102 then checks whether the entire data word may already have been saved, which will be overwritten if necessary, otherwise a new, empty storage space will be created described.

This method requires at least 3 bits for the information about the channel selection, i.e. the information as to which of the eight outputs of the timer 109 is to be activated, and at least 4 bit information for function selection, i.e. for the concrete timing of this output according to Table 1. Overall, it is expedient to see at least 8 bits for the two aforementioned information. A further 4 bits of the BCD inputs 20 contain the Information about the entire available time frame. During the Programming or while learning, all this information is shared with the Data word stored, which is emitted by the transmitter and via the HF receiver, the demodulator 10 and the serial input 101 is detected. As soon as consecutive If exactly the same data word has been received twice, this will be sent together with the aforementioned information is stored in the RAM memory 102. That from the broadcaster The transmitted data word can, for example, consist of a 20 to 24 bit long, there are codeword permanently assigned to the transmitter as well as some changeable additional bits, which are changed, for example, by the fact that different keys or key combinations be operated on the transmitter. Corresponding keys or key combinations could, for example, be labeled with the different functions that are used for Programming was "learned" during the relevant key press. The In this respect, the receiver almost the entire amount emanating from the transmitter in a later comparison Information as a code word or comparison word, the presence of which in the memory 102 is checked. If he finds this "code word", he releases the associated functions on the associated output or channel.

If another button is pressed on the transmitter, the actual code word of the Transmitter does not change, but the bits assigned to a specific function change in the data word sent. Because the same key was used beforehand when programming or key combination of the transmitter has been pressed, it is changed accordingly Data word along with the associated channel and function information in the memory 102 has been filed. So later the same key or key combination of the Operated transmitter, the data word in question is only together with this channel and Functional information found in memory 102, which was also previously used for programming same button press on the transmitter were stored in the memory 102 of the receiver. Man generally receives a unique assignment between a certain key press or a key combination on the transmitter and the function to be triggered, so that the Transmitter buttons can be labeled or labeled accordingly. Here is the However, users are completely free to assign any output channels and functions to each any key or key combination of the transmitter. In addition, it is of course also possible, with one and the same button press and thus with one and the same from the transmitter outgoing data word several different channels with the same or different Activate or trigger timing behavior. This is simply done in programming mode corresponding to various selected channels and functions via inputs 43, 44 "Learned" the same transmitter word by using the same sender word sent, i.e. the same transmitter key or key combination is pressed. If the transmitter is used later and this data word is sent, the logic takes place 108 the relevant data word two or more times in the memory 102, in each case together with different channel or function options, so that the Timer 109 a corresponding number of channels with the selected and in Controls stored timing behavior.

The programming of the system is facilitated by the fact that the display controller 111 is on the LCD display 50 the selected channels by numbers and the selected functions indicated by letters or special characters according to Table 1. In the used 7-segment displays, for example, the letters "S" and "I" from the numbers "5" or "1" simply distinguished by a point after it. It is also next to it possible to display the digits only in the right segment field, while single letters in the left Segment field are displayed. Characters in both segment fields are always letters.

In order not to lose the stored data in the event of a power failure, EEPROMS 60 Provided at the outputs 61, 62 of an EEPROM controller 110 integrated in the chip are connected. In principle, a mode would also be conceivable for the function and channel selection, at which a certain storage space is deleted. However, one can also access delete the EEPROMS in this specific, stored data words and information by by interrupting the power supply, the entire memory 102 is erased and then corrected data can be read back into the system in the EEPROMS. As soon as the power supply is restored, the EEPROM controller 110 begins Reading of all data stored in the EEPROMS 60 into the RAM memory 102.

It goes without saying that the chip 100 can also be used with other ones, not described in more detail here Elements can be equipped, in particular also with a test circuit 120 and corresponding test connections 121.All other functions, i.e. especially that of serial input 101, comparator 107, logic 108, timer 109 and Address control permanently programmed or "hardwired", i.e. Functional changes are not programmable, but only memory contents can be stored in memory 102 be changed, which is ultimately just a selection of different channels and one for each channel Allows selection of the time behavior within the scope of the options specified in Table 1.

The operating cycle of the chip 100 is determined by the oscillator 104, which in turn is determined by an external quartz with a nominal oscillation frequency of 32 kHz via inputs 31, 32 is stabilized. Since the internal data bus width when accessing the memory 102 and when Comparison with the received data words corresponds to the length of the stored data words, accordingly, a full word comparison can be made with each bar, so that even then, if multiple data word reception and comparison for triggering a function it is assumed that the processing time for the data word until the function is triggered is negligible and typically in the range of or below a thousandth of a second lies.

The receiver according to the invention thus fulfills the function of a group of remotely controllable ones Relays with any predefinable time behavior and with a restricted one at the same time Access authorization according to the saved transmitter codes. A single recipient can trigger a large number of units and perform different functions, also arbitrary assignments between certain channels and through them triggerable functions can be made.

Claims (17)

1. A method of decoding and converting encoded remote control signals, in which a pulse train received by way of a high-frequency feed in a receiver is converted into a digital data word and at least partially compared to code words stored in the region of a receiver in order after a possibly positive comparison result to trigger at least one predeterminable function, wherein together with or beside a code word at the receiver end there is stored a function which is associated with the code word and which is to be triggered upon reception of the code word so that the sent data word besides the code component also acquires at least one item of information about a function to be triggered and the comparison of the received data word with the stored code words also includes comparison of the items of information about the function to be triggered, characterised in that a freely selectable association of functions to be triggered with the stored code words occurs at the receiver end.
2. A method according to claim 1 characterised in that triggering of the function associated with the received data word occurs independently of the storage place of the stored comparison data and only on the basis of the content of the received data word and identity with stored data.
3. A method according to one of claims 1 and 2 characterised in that at least two different functions can be triggered, with each of which are associated respectively different information data in the data words and the stored comparison words.
4. A method according to one of claims 1 to 3 characterised in that the information data about a function to be triggered are stored with a respective code component jointly as a data block at the receiver end.
5. A method according to one of claims 1 to 4 characterised in that the code component of the transmitter together with the transmitted items of information about a function to be triggered, possibly including the time characteristics thereof, is interpreted and treated overall as a code word at the receiver end.
6. A method according to one of claims 1 to 5 characterised in that the information data stored in relation to a data word are read in parallel out of a memory and compared to the corresponding information data of the received data word.
7. A method according to one of claims 1 to 6 characterised in that items of stored information about a time delay are associated with each function to be triggered, wherein the function is triggered with a time delay corresponding to the time delay information after the receipt of a data word and a concluded positive comparison with stored values.
8. A method according to claim 7 characterised in that the time delay information can be inputted into the transmitter or receiver from the outside and altered.
9. A method according to claim 7 or claim 8 characterised in that the time delay information can be stored together with the data block which contains the code word in question and the information about the function to be triggered.
10. A method according to claim 8 or claim 9 characterised in that the information data about code, function and/or time delay are provided at predetermined positions in the data word sent.
11. A method according to one of claims 1 to 10 characterised in that the internal clock frequency for reading and comparison of the received data word corresponds at most to 1/10 of the transmission frequency of the remote control signals.
12. A method according to claim 11 characterised in that the clock frequency is less than MHz, preferably less than 100 kHz, while the transmission frequency is greater than 10 MHz and is preferably about 27 or about 40 MHz.
13. Apparatus for converting encoded remote control signals which issue from a remote control transmitter and comprising a receiver with

    a) a current/voltage supply,

    b) an HF-receiving portion with demodulator,

    c) a decoder unit,

    d) an interface,

    e) a memory, and

    f) a control logic, wherein

    h) the interface has a plurality of outputs for different functions,

       characterised in that the control logic has a structure or a programming which permits the freely selectable association of stored code words which contain at least one information component about a function to be triggered with each of the outputs, and compares the received remote control signals to the stored code words.
14. Apparatus according to claim 13 characterised in that it has a memory management (MCTR) with parallel access to the information units contained in the stored data words.
15. Apparatus according to claim 13 or claim 14 characterised in that the decoder, the memory and the control logic are arranged on a common semiconductor circuit (chip).
16. Apparatus according to one of claims 13 to 15 characterised in that the memory has a minimum capacity of 30 data words of 60 bit length.
17. Apparatus according to one of claims 13 to 16 characterised in that adjustable time delay units are connected between the control logic and the outputs.
