Description
The present invention relates to the remote control of operating electronic equipment, and be particularly related to able to programme with a kind of general remote-control device in the electronic equipment of operating the number of different types of producing by different manufacturers.
General remote-control device is can being programmed to it so that operate a kind of device in the electronic equipment of the number of different types of being produced by different manufacturers by the user of knowing.General remote-control device is through being usually used in control audio/video equipment, as TV, VCR, CD Player etc.Because their programmability, so the consumer usually uses general remote-control device to replace the remote control lost and/or control some independently audio/video elements as single control device.
Before using, generally must programme so that can work to general remote-control device with controlled electronic equipment.A general remote-control device programmed generally include: an identification and reference code or some other identifying information relevant with the correct signal form store in the memory circuit of this general remote-control device.In case programme, general remote-control device just sends the control signal with the signal format that is suitable for controlled device.This signal format is by comprising but be not limited to carrier frequency, pulse duration, pulse modulation and total regularly characteristic decision.
Have several to the general remote-control device method that has a control signal of desirable signal format with transmission of programming.A kind of method is manually to import the reference code relevant with controlled device.In the method, the reference code inventory of various device model be included in general remote-control device with the instruction set of printing in.The user seeks the reference code relevant with controlled device and by being positioned at the manual input code number of numerical key on the general remote-control device.The user is problem in this way, for general remote-control device is programmed, must know specific reference yardage.Therefore, must preserve the reference code inventory nearby, and can inquire about when a fresh code maybe needs to re-enter a particular code must importing.
The another kind of method that general remote-control device is programmed is automatic code search and storage method.In the method, by sending the remote signal based on the every kind signal format of storage in the inventory according to priority, general remote-control device is cyclic search signal format group automatically and continuously, till user's stop signal form search sequence.By by the key of one group of appointment, the user begins and keeps automatic search sequence.During cyclic search signal format, whether remote control suspends between each signal format to allow the user to observe controlled device and certain particular signal formats is responded.When controlled device reacted to remote signal in the way you want, signal format that the user is just correct as can be known and correct reference code therefore were identified, and stop automatic search sequence.Stop the cyclic search that this search sequence can make general remote-control device stop signal form, and reference code or other identifying information relevant with the signal format of nearest transmission stores in the memory circuit into.
The example of the system of an employing the method is open in EP-A-0 233 307.The system of the disclosure is a remote control, and by responding first input, this remote control produces and transmits a remote signal sequence, and wherein each signal all has different-format.User's facilities for observation and wait for that this equipment reacts in a kind of mode of expection.When this equipment was reacted, the user provided second input, and it makes this remote control preserve the last signal format that transmits.
Automatically the disadvantage of search method is that the method requires the user to react in the cycle at a predetermined time out.When controlled device is reacted to a remote signal according to expection, the user must react in the cycle at the time out that is distributed, so that the cyclic search of stop signal form and a reference code relevant with desirable signal format store in the memory circuit.If the user divert one's attention at this moment and/or reaction too slow, then may store inappropriate reference code in the memory into, thus the user must the duplicated code search operation with searching with store correct reference code.This shows that if the user over and over again can not react in the cycle at the time out that is distributed, it is difficult and a tax on one's mind that then this method can become.
Also having a kind of method that general remote-control device is programmed is semi-automatic code search method, and wherein the user progressively searches for a plurality of signal formats that are stored in the storage area, till the signal format that finds hope.In the method, the remote signal that transmits a remote signal sequence and each transmission by the key by one group of appointment one at a time all has a different signal format, and the user can progressively search for the signal format group that is stored in the memory.After each remote signal form transmitted, the user will observe the reaction of controlled device to this transmission signal, that is, and and on electric power on/off or the channel/down.When this equipment was reacted to signal by way of expectations, the user had just transmitted the appropriate signal form as can be known.At this moment, the user is by another group key termination code search operation, and reference code or other identifying information relevant with the signal format of last transmission stores in the memory circuit.
Use the difficulty of said method to be, because in memory circuit, stored a large amount of possible signal formats, a large amount of signal format so the user had to progressively search for before recognizing correct signal format.In fact because can use long form inventory, so reference code from double figures to three figure places and four figures can become more and more longer.This shows that this difficulty can make the method become irksome and consuming time.If desirable signal format is stored in the part near the ending of signal format inventory, so this method more is a problem.
What we needed is a kind of improved method, and it can be programmed to general remote-control device quickly and easily so that transmit remote signal with a kind of signal format of hope.Special hope needn't be with reference to the reference code inventory of printing and is manually imported specific reference code and just can programme to general remote-control device in general remote-control device.Wish also and can programme to general remote-control device that wherein the user can control the speed that transmits and check the signal format of being stored fast and convenient and effectively by the signal format group of cyclic search storage.
The present invention relates to a kind of general remote-control device and a kind of method that general remote-control device is programmed, it allows the user to check the signal format group of being stored quickly and easily, store in the memory circuit thereby discern a desirable signal format and reference code or other identifying information relevant with the signal format of this hope, remote signal so subsequently will transmit with the signal format of this hope.
General remote-control device of the present invention comprises a signal transmitter, allows one data input device in user input data and a plurality of code search order, a memory circuit and a controller.Controller produces and one group in a plurality of remote signal groups is applied in the signal transmitter by the first code search command of response user input.Every group of remote signal comprises that a plurality of remote signals and each remote signal have based on the signal format separately that is stored in the signal format inventory in the memory circuit.Controller also produces and uses one of them remote signal from the remote signal group of nearest transmission by response user's second code search command.The relevant identifying information of signal format that controller exits command storage and transmits recently by the code search that responds the user.Be valuably, by responding the second code search command of each user's input, controller produces with first predefined procedure and the remote signal from the remote signal group of nearest transmission is applied to signal generator, by responding the third generation code searching order of each user input, controller produces with second predefined procedure and the remote signal from the remote signal group of last transmission is applied to signal generator.
The present invention allows the user to comprise the signal format group of desired signal format by input first code search command quick identification, and passes through input second and the third generation code searching command key quick identification desirable particular signal formats from the signal format group of this identification subsequently.
The invention still further relates to a kind of method that general remote-control device is programmed, the step that comprises is: by send a plurality of sets of signals up to can be observed controlled device by way of expectations in response till, thereby identify the sets of signals that comprises desired signal format; Be contained in remote signal form in this identification signal group till can be observed controlled device and responding by way of expectations by independent transmission, thereby in the sets of signals of this identification, identify desirable signal format; And the relevant identifying information of this identification signal form in storage and the memory circuit is as reference code.
