Abstract
Abstract Initially, control data are transmitted from the pickup of the remote control to the system when the remote control is initially operated. The system responds to the control data and transmits the current system values back to the pickup of the remote control where, after verification of the current system values data received by the remote control pickup, a control command is transmitted by the remote control pickup to the system, with the command causing the system to accept the control data transmitted by the initial operation of the remote control.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
135 words
A method of operating a system by a remote control, wherein control of the system is in a two-way mode with a bidirectional data transmission between the remote control and the system, said method comprising the steps of: transmitting control data from said remote control to said system when said remote control is initially operated; in response to receipt of said control data, transmitting the current system values from said system back to said remote control; receiving the transmitted current system values and verifying same in said remote control; after said step of verifying, transmitting a control command from said remote control to said system; and receiving said control command in said system and, in response to receipt of said control command, accepting the control data transmitted by said initial operation of said remote control.
Claim 2
Independent Claim
135 words
A method of operating a system by a remote control, wherein control of the system is in a two-way mode with a bidirectional data transmission between the remote control and the system, said method comprising the steps of: transmitting control data from said remote control to said system when said remote control is initially operated; in response to receipt of said control data, transmitting the current system values from said system back to said remote control; receiving the transmitted current system values and verifying same in said remote control; after said step of verifying, transmitting a control command from said remote control to said system; and receiving said control command in said system and, in response to receipt of said control command, accepting the control data transmitted by said initial operation of said remote control.
Claim 3
Dependent Claim
26 words
A method according to claim 1, further comprising the step of displaying the received said current system values on a display means in said remote control.
Claim 4
Dependent Claim
71 words
A method according to claim 1, wherein said bidirectional data transmission from said remote control to said system and from said system to said remote control are in the form of data telegrams via a transmission path, wherein said data telegrams are made up of pulses or pulse sequences of a predetermined carrier frequency, and wherein the respective bit value is coded using the pulse length of the carrier frequency pulses.
Claim 5
Dependent Claim
27 words
A method according to claim 3, wherein different data telegrams are transmitted from said remote control to said system depending on the status of said remote control.
Claim 6
Dependent Claim
37 words
A method according to claim 4, wherein said data telegrams transmitted by said remote control comprise one of power-on information, an enquiry of the current system values, new control data for the system and an acknowledge command.
Claim 7
Dependent Claim
24 words
A method according to claim 3, wherein said system transmits only one system data telegram containing the current system values to said remote control.
Claim 8
Dependent Claim
136 words
A method according to claim 5, wherein: said step of transmitting control data is initiated upon operation of said remote control to switch on said system to enquire the current system values or to enter new control data for said system, and includes transmitting the appropriate remote control data telegram via said transmission path to said system where it is evaluated and checked; said step of transmitting current system values includes transmitting said system data telegram with the current system values back to said remote control via said transmission path; said step of transmitting a control command includes transmitting said acknowledge command telegram from said remote control to said system via said transmission path to effect transfer of the transmitted data of said remote control data telegram if the data has been transmitted free of errors.
Claim 9
Dependent Claim
61 words
A method according to claim 7, wherein the respective steps of receiving by said system and by said remote control include the sequential steps of receiving, filtering, evaluating, decoding and checking the pulse sequences of the respective data telegrams with the aid of a respective series arrangement of a receiver, a filter element, a signal processing stage and a computer, respectively.
Claim 10
Dependent Claim
64 words
A method according to claim 8, wherein said step of evaluating includes integrating the received and filtered pulse sequences of said data telegrams by said signal processing stage, with the output level of said signal processing stage changing at a certain threshold value, and retaining said output level in this switching state until no more pulses are being received from the associated said receiver.
Claim 11
Dependent Claim
43 words
A method according to claim 9, further comprising initiating an interrupt routine upon changeover of the output level of said signal processing stage, with the data transferred by means of pulse sequences being read in, checked, decoded and evaluated during said interrupt routine.
Claim 12
Dependent Claim
29 words
A method according to claim 10, wherein the respective said computer comprises a respective micro processor, and wherein said transmitted data are stored in an associated respective said microprocessor.
Claim 13
Dependent Claim
53 words
A method according to claim 1, wherein: said bidirectional data transmission takes place in alternating time intervals, with each said time interval in which data transmission takes place is followed by a time interval in which no data may be received by an associated receiver of said remote control or of said system.
Claim 14
Dependent Claim
58 words
A method according to claim 1, wherein said step of verifying further includes in the event of a faulty transmission, so that no verification can be found, transmitting no return control command signal from the remote control, and further comprising the step of repeating the transmission of the current system values when said return signal is not received.
Claim 15
Dependent Claim
23 words
A method according to claim 13, wherein said step of repeating includes repeating the transmission twice when said return signal is not received.
Claim 16
Dependent Claim
51 words
A method according to claim 1, wherein said step of transmitting a control command include transmitting three consecutive control command signals to said system from said remote control as acknowledge commands, and further comprising ignoring other received acknowledge commands in said system after one of said acknowledge commands has been recognized.
Claim 17
Dependent Claim
15 words
A method according to claim 1, wherein said data transmission is in the IR range.
Claim 18
Dependent Claim
17 words
A method according to claim 16, wherein the carrier frequency for the data pulses is 400 kHz.
Claim 19
Independent Claim
172 words
A method of operating a system by a remote control, wherein control of the system is in a two-way mode with a bidirectional data transmission between the remote control and the system, said method comprising the steps of: transmitting control data from said remote control to said system when said remote control is initially operated; in response to receipt of said control data, transmitting the current system values from said system back to said remote control; receiving the transmitted current system values and verifying same in said remote control; after said step of verifying, transmitting a control command from said remote control to said system; and receiving said control command in said system and, in response to receipt of said control command, accepting the control data transmitted by said initial operation of said remote control; wherein data communication is accomplished using non-line-bound transfer segment and a low data-transfer speed as compared to a line-bound transfer speed; and wherein a transfer frame for a successful transfer of data ends after three communication cycles.
Claim 20
