Abstract

PURPOSE:To send plural control signals made by different manufacturers continuously by one key operation by receiving a signal of remote controllers made by different manufacturers at a reception section sequentially and providing a storage section storing the data to the remote controller. CONSTITUTION:A changeover switch 16 of the remote controller 15 is set to the storage mode and by depressing a reproduction button 30, a computer outputs an address corresponding to the button 30 to the memory. Then when a power switch signal of a general remote controller 1 is sent, the device 15 receives it by a photodetection section 22 and the data is stored in the said memory. Similarly, the CH 1 of the device 1 and the power switching of a television receiver are inputted and stored in the said memory. The video power supply and reproducing signal of the remote controller 2 are stored similarly. When the switch 16 is set to the transmission mode and the button 15 is depressed, the stored data is read in the order of registration and a remote control signal is reproduced based on the data and outputted continuously.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a remote control device for audiovisual equipment and the like.

BACKGROUND ART FIG. 4 is a system configuration diagram of a conventional remote control device, FIGS. 6 Δ to C are transmission waveform diagrams thereof, and FIGS. 6 a to c are front views of the conventional remote control device.゛This will be explained below based on the drawings.

In FIG. 4, when the remote control device 1 attached to the television receiver 6 is operated, a signal & is transmitted, and the television receiver 6 receives it and operates. On the other hand, when the remote control device 2 attached to the video deck 6 is operated, a signal is transmitted, and the video deck 6 receives the signal and operates. The same applies to the video deck, the remote control device 3 attached thereto, and the signal C transmitted from the remote control device 3.

Signals a and b consist of a head pulse d, a 6-bit custom code e, and a 6-bit data code f, as shown in FIG. The head pulse d indicates the start of the remote control transmission signal, and the custom code e indicates the start of the remote control transmission signal. The 06-bit data code, which is different for each device such as a video deck 6 or T, and is used to distinguish between each other's operation targets, is used in the television receiver 6 as the T source O.
N.

OFF, channel 1. Channel 2, etc., and video deck 6 or 7 are assigned by function such as playback, stop, etc., and up to 64 functions can be assigned. Signal C is only data code f.

By using such a signal, the following actions and effects can be obtained.

As a function, the television receiver 5 is operated by the data code f accompanied by the predetermined custom code e, and therefore is operated only by the signal a transmitted from the remote control device 1.
Remote control device 2. A signal transmitted from the remote control device 3,
It does not work in c.

Similarly, the video deck 6 is operated only by signals transmitted from the remote control device 2. The video deck 7 is also operated only by the signal C transmitted from the remote control device 3. Therefore, the video deck 6.7 cannot be operated by the remote control device 1. The same applies to others. It cannot be operated with anything other than the remote control device that comes with the tab.

As an effect, the operator turns on the power of the television receiver 6.
When operating the remote control device 1 with the intention of turning it off, the desired operation can be performed accurately without the video deck 6 or 7 operating.

Although such an effect can be obtained, it is common to install the television receiver 5 and the video deck 6 or γ at the same place and operate them at the same time. If you want to play a videotape on the video deck 6 or 7 at the same time as operating it at hand, turn on the power to the television receiver 5, set the channel to 1',
Next, the video deck 6 or 7 was turned on, the antenna was switched to video, and then playback started.

Problems to be Solved by the Invention In such a conventional configuration, if the remote control devices 1 to 3 attached to the television receiver 6 and the video deck 6 or 7 are manufactured by the same manufacturer, even if they are designed by different departments, the design technology may differ. Unification can be done relatively easily; both the television receiver 6 and the video deck 6 or 7 can be operated with one unit, and both the television receiver 6 and the video deck 6 or 7 can be operated with a single key operation. Although it is possible to realize a remote control device that can output multiple operation signals, general consumers do not necessarily use a combination of a television receiver 5 and a video deck 6 or 7 from the same manufacturer. First, when combining a television receiver 6 and a video deck 6 or 7 made by different manufacturers, two remote control devices were used to perform each operation. Remote control devices from different manufacturers have different transmission waveforms, so in order to combine them into one device using conventional technology and output multiple signals with a single key operation, various combinations can be made, and a specific method specified by the manufacturer is required. It has not been put into practical use because it is technically difficult and expensive because only multiple signals can be output.

The present invention solves these problems and provides an inexpensive remote control device that can transmit arbitrary signal waveforms in the order of registration.

Means for Solving the Problem In order to solve this problem, the present invention includes a receiving section, a driving section, a key input section, and a storage section for storing a plurality of data in registration order in response to one key input. , extracting data for reproducing the remote control signal received by the receiving unit from the remote control signal, storing the data in the storage unit in an extraction class, and inputting the key. Based on the data read from the storage section in response to input from the drive section, a plurality of remote control signals are reproduced in the order in which the registration data was registered and outputted via the drive section.

Therefore, according to the present invention, signals of remote control devices of different manufacturers are provided, including a receiving section, a driving section, a key input section, and a storage section that stores a plurality of data in the order of registration in response to one key input. can be received in order by the receiving section and stored in the storage section in the order in which they were transmitted, which has the effect that a plurality of control signals from different manufacturers can be transmitted continuously with a single key operation.

Embodiment FIG. 1 shows a front view of an embodiment of an infrared wireless type remote control device according to the present invention, and FIG. 2 shows a block diagram of its circuit. The following will explain FIGS. 1 and 2 with reference to FIG. 6, which is a conventional diagram.

Signals are registered in the input key so that when the playback key of the remote control device of the present invention is pressed, optical signals for TV power, CR1, video power, antenna switching, and playback are serially generated. Explain the method.

First, the slide type changeover switch 1 of the remote control device 16
Set 6 to the memory side and set it to memory mode. As a result, even if a button on the remote control device 15 is pressed, no transmission occurs.

The 18 buttons on the remote control device 16 correspond to the key matrix 17 in FIG. When the playback button 3o is pressed in the storage mode, the microcomputer 19 detects from the key matrix 17 that the playback button 3o has been pressed, and outputs the address corresponding to the playback button 3o to the memory 20. Memory 20 is of the random access type. Next, a signal for turning on and off the power of the general television receiver remote control device 1 shown in the conventional example shown in FIG. 6 is transmitted.

Next, the transmission signal 21 is received by the light receiving section 22 in the remote control device 16, amplified to a voltage level that can be input to the microcomputer 19, and outputted. The microcomputer 19 samples the signal input from the light receiving section 22 in time series, converts it into quantized data, and stores it in the memory 2.
Stored at the address of o.

In the same procedure, CH1 of the remote control device 1 is input, and the TV receiver is turned on 10 FF, and then stored in the address of the memory 20.

Using the same procedure, the video power source, antenna switching, and reproduction signal of the remote control device 2 are stored in the address of the memory 20.

Next, the changeover switch 16 of the remote control device 16 is set to the transmission mode.

By the above procedure, the power supply of remote control device 1 is set to 0N10FF.
, CHl, video power supply of remote control device 2.

This means that the data transmitted when the antenna is switched and the playback button is pressed is continuously stored in the address of the memory 20 corresponding to the playback button 30 of the remote control device 15.

When the changeover switch 1e is set to the transmission mode, the changeover switch 16 of the remote control device 15 is set to the transmission mode.When the playback button 3o of the remote control device 16 is pressed, the microcomputer 19 selects the playback button 3o from the key matrix 17. , detects that it has been pressed, and outputs the address corresponding to the playback button 30 to the memory 20. The address is output to the memory 2o. The microcomputer 19 reads out the data stored at the address in the order in which it was registered.
The transmitter 2 regenerates a remote control signal based on the data.
Output to 3. The transmitter 23 converts it into infrared light and continuously outputs it as a remote control transmission signal 24.

This remote control transmission signal 24 and the power supply of the remote control device 1 are 0N.
The remote control transmission signals sent from the remote control device 1.2 when the video power, antenna switching, and play buttons of the remote control device 2 are pressed successively are the same.

The function display section 25 is a plain label on which the operator writes symbols and characters that will help him understand the memorized functions.

FIG. 3 shows a waveform 9 of the received remote control transmission signal 21,
The relationship between the sampling b for converting the waveform into data to be stored in the memo IJ20, the sampling data C, the memory 2o, the timing d for reading out the data stored in the memory 2o and reproducing the waveform, and the reproduced transmission waveform e. show.

Data C is obtained by quantizing the received waveform using a sample timing b whose period is shorter than the minimum pulse width U of the received signal waveform &. This data C is stored in and read out from the memory 20. By sequentially outputting the data C according to the output timing d having the same period t as the period C of the sample timing b, a transmission waveform e is obtained by reproducing the reception waveform λ. When the transmitted waveform e is compared to the received waveform, an error occurs due to quantization. The maximum error is the period t of the sample timing b.

Therefore, in order to reduce the error between the received waveform a and the transmitted waveform e, it is sufficient to make the period of the sample timing b sufficiently small with respect to the minimum pulse width U of the received waveform a.

Effects of the Invention As described above, according to the present invention, a plurality of remote control devices are kept at hand for using remote control devices attached to each device to remotely control a plurality of devices such as a television receiver and a video deck. Each time you perform an operation, you can perform multiple operations with a single button operation by storing the transmitted signals of multiple remote control devices in one button in sequence. This eliminates the need for remote control devices attached to each device.

Therefore, it is possible to eliminate the hassle of selecting and switching all the necessary remote control devices from multiple remote control devices, and to improve operability by producing the same effect as pressing multiple buttons by pressing one button. It will be done.
