Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a learning remote control transmitter used for various electronic devices such as a television receiver, and more particularly, to a plurality of individual transmitters. A reconfigurable learning remote control transmitter that can be programmed to emulate any of the remote control signals.

2. Description of the Related Art Referring to FIGS. 5 to 9, the operation and configuration of a conventional learning remote control transmitter will be described. Reference numeral 101 denotes a remote control transmitter to be emulated. PIN diode 112 of machine 111
The learning mode is changed from the normal mode 126 (the mode in which the learned remote control signal is transmitted when the key 124 of the learning remote control transmitter 111 is pressed) from the learning mode to the learning mode. Switch to 127 (mode for learning the signal of the remote control transmitter 101 that you want to emulate to a specific key 124 of the learning remote control transmitter 111), and confirm on the display circuit 121 that the learning remote control transmitter 111 is in the learning mode 127. I do. After that, the key 103 of the remote control transmitter 101 to be emulated is pressed to transmit the optical signal 104 from the light emitting unit 102.

The transmitted optical signal 104 is the PI of the learning remote control transmitter 111.
Received by N diode 112.

The PIN diode 112 is a photoelectric conversion element that converts the optical signal 104 from the remote control transmitter 101 to be emulated during the learning mode into an electric signal. The converted electric signal faithfully amplifies the incoming signal. This is sent to preamplifier section 113.

The signal output from the preamplifier unit 113 is transmitted to the next frequency circuit 1
14 and a waveform shaping circuit 117.

First, the frequency circuit 114 is a circuit for measuring the frequency of a pulse in each burst of a pulse group (hereinafter referred to as a carrier frequency) by a frequency counter 115 inside the frequency circuit 114 in the learning mode. The carrier frequency is measured by measuring the number of clocks output from the basic clock generation circuit 123 for driving the carrier. In addition, in the normal mode, the circuit is a circuit that measures in the learning mode when the key 124 of the learning remote control transmitter 111 is pressed and generates the carrier frequency simply by setting the stored carrier frequency value in the frequency counter 115.

In the frequency circuit 114, in the learning mode, the preamplifier 1
Measure the carrier frequency of the remote control signal coming from 13.
The carrier frequency is set to the latch
Output to 6 and latched.

The remote control signal output from the preamplifier unit 113 is
It enters the other circuit, a waveform shaping circuit 117 for extracting the envelope curve of the remote control signal. The signal output from the waveform shaping circuit 117 is a pulse signal from which the carrier frequency component of the remote control signal has been removed.
., The pulse widths T1H, T1L, T2H, T2L, T3H, T3L... Shown in FIG. As shown in (b), the data is stored in a random access memory 122 (hereinafter referred to as SRAM).

Next, a method of measuring the pulse width of the remote control signal will be described with reference to FIG. A change in the envelope curve input of the remote control signal, that is, the rising edge of the pulse of the remote control signal is detected, and an interrupt 128 is applied to the microprocessor 120. Then immediately microprocessor 1
Start counting the number of frequency-divided clocks (divided by 16 in this case) divided by the clock frequency divider 129 output from the basic clock generator 123 that drives 20 and measure the pulse width T1H To start. That is, “pulse width = count number of clock”. Then, at the same time as the falling of the pulse, the microprocessor 12
The interrupt 128 is again applied to 0. Immediately thereafter, the microprocessor 120 stops counting the divided clock and immediately transfers the measured pulse width T1H data to the SRAM 122.
In a work area with a capacity of about 500 bytes.

Further, the data of the counter 119 of the pulse width circuit 118 is immediately cleared, and the counting of the next pulse width T1L is started. The microprocessor 120 waits for time until the next rise of the pulse width T2H, or performs another job. At the next rising edge of the pulse width T2H, the counting is stopped, and the pulse width T1 of the envelope curve is set in the same manner as described above.
The L data is taken into the work area of the SRAM 122. In this manner, counting is performed until the work area of the SRAM 122 becomes full, and the work of storing the count is continued. At the same time as the termination, the data of the carrier frequency measured by the frequency circuit 114 is taken into a predetermined area of the SRAM 122. This completes the capture of data from the remote control transmitter to be emulated.

For the following description, a portion of the remote control signal where the carrier frequency is on is called a mark, and a portion without the carrier frequency is called a space. That is, the data in which the remote control signal is taken in is written in the work area of the SRAM 122 alternately by space and 2 bytes starting from the mark.

Next, the method of compressing and registering the data taken into the work area of the SRAM 122 will be described.
The first compression of the envelope curve data of the remote control signal taken into the work area of AM122 is based on the combination of mark and space as one unit, and classified into several groups of pulse widths. 4 in group
Pulse number composed of bits (in hexadecimal notation) 1,2, ...
.. A, F,... F, and the 2-byte data stored in the work area is replaced with the pulse number.

For this purpose, first, the mark and space data taken into the work area data of the SRAM 122 are shown in FIG. 6 (c).
Mark, mark + space ("Mark +
Space ").
Register again.

Next, the method of classifying the pulse width will be described with reference to FIG. 7. The classification of the pulse width is performed in order to classify the mark and the period into several pulse numbers. Grouping is performed so that marks and periods are appropriately classified into a certain number, and a lower limit value, an intermediate value, and an upper limit value are determined.

That is, the mark and the period upper limit value and the lower limit value are set for each of the pulse numbers 1, 2, 3,... Used. Next, as shown in FIG. 8 (a), the data stored in the work area is compared with the upper limit value and the lower limit value and replaced with data of an intermediate value. , 2, 3,..., And the pulse number is set to an intermediate value which is a representative value of the 2-byte width data of the mark and the period.
FIG. 8B is an explanatory diagram in which the remote control signal is represented by a pulse number.

In this manner, the first compression is performed by replacing the mark and space composed of each 2 bytes of the remote control signal with the pulse number composed of 4 bits.

In the next compression, the encoded remote control data, that is, the data of each key, must be further compressed.

FIG. 9 shows the compression process. This process is also a step of eliminating code repetition in the remote control code.

As shown in FIGS. 9A and 9B, the first number is compared with the second number, and if they do not match, the first two numbers and the next two numbers are compared. Compare.
And if the two numbers do not match again,
Compare the first three numbers with the next three numbers. In this way, the comparison is continued by increasing the number by one until the first half of the number stored in the work area is compared with the other half stored. If the match is still not found, the comparison is repeated from the beginning, but the first 1
The numbers are omitted, and if no match is found, the next two numbers are omitted. FIG. 9A shows a case where there is no head signal. “121213” is repeated. Therefore,
What is necessary is just to store the pulse number sequence “121213” and the fact that the leading pulse number of the repetition part is the 0th.

FIG. 9B shows a case where there is a head number. “12”
Is a head signal, and “3435” is a repetition signal. Therefore, it is only necessary to store the pulse number sequence “123435” and the fact that the first pulse number of the repetition portion is the second. As a result, the remote control data is compressed.

That is, the emulated remote control signal stored in the work area of about 500 bytes of the SRAM 122 includes the data number, the carrier frequency data, the number of types of pulse width data, the single-shot signal or the continuous signal, and the repetition number. The data which is converted from the pulse number to the data of the pulse width or the like and is sequentially compressed at a predetermined address of the SRAM assigned to the key number is registered.

In this way, the data of the captured remote control signal is compressed to a manageable storage size, and all of the data is re-decompressed to an uncompressed format to retransmit the data during emulation, The compressed data will also be retained.

Thus, the learning process and the storing process are completed. These steps are common to all keys in the emulated transmitter.

Next, an outline of the operation of transmitting the emulated signal by the transmitter 111 will be described. In order to transmit the emulated signal, it is possible to read out, expand, and send the stored code required by the transmitter. Required. This is done by first determining which source has been selected so that the correct data block in SRAM 122 is addressed. Then, a certain key 124 is pressed, and a predetermined data block is copied to the work area of the SRAM. At the same time, for remote control code duplication,
The compressed code is decompressed. Then, a start value, a length value, a value of the number of repetitions, and the like are added to the copied code. The remaining operation to be performed is to generate the required carrier frequency. This is performed by setting predetermined data in a frequency counter of the frequency circuit 114. A basic clock for driving the microprocessor 120 is input to the frequency circuit 114. The number of the basic clock is counted up to the set data, and when the value becomes the same, the output of the frequency counter 115 is inverted. It has become. By repeating this operation, a carrier frequency is created.

When transmitting the expanded code, first, the output of the pulse width counter 119 is set to “H” at the start of transmission, and the first data is set in the pulse width counter 119. After that, the data is subtracted one by one. The data
When it becomes "0", the output of the pulse width counter is set to "L". Then, the next data is set in the pulse width counter. Then, the same operation as described above is repeated.

The envelope curve of the emulated remote control signal is reconstructed. By taking the carrier frequency, the envelope curve, and the AND 130, it is possible to reconstruct the remote control signal. The reconstructed remote control signal is
By driving the infrared light emitting diode 132 through the driving circuit 131, the electric signal is converted into an optical signal and transmitted to a television receiver or the like that operates with the emulated remote control transmitter, thereby receiving the television reception signal. Machine can be operated.

In this way, a reconfigurable remote control transmitter that can emulate several remote control transmitters, is easy to operate, and does not require interconnection or modification of the controlled devices is provided.

However, as described above, after learning a remote control code for a predetermined key, when the registered remote control code is to be changed, the editing function of moving, exchanging, copying, etc., has been performed until now. There is no learning remote control transmitter having the above, and the learning operation and the like must be performed again from the beginning to perform the movement, the copy, and the like.

Further, even if the registered remote control code is erased by mistake using the delete key, the remote control code data cannot be restored, and such an error has to be re-learned again from the beginning and stored. Also, when exchanging the keys, if the memory registration capacity of the remote control data is the same, it can be realized by exchanging the remote control data of the keys as they are. Because it was packed and registered, it could not be exchanged without moving the data in the memory. In addition, there has been a problem that one of the data cannot be stored in the memory unless it moves.

In addition, there is a remote control with a multi-command key that has the function of continuously outputting the learned remote control signal when the remote control key is pressed only once. In fact, it was difficult to use multi-command keys even if they were learned by grouping into TV, video, audio, etc. . An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a learning remote control transmitter capable of easily editing, such as moving, copying, and exchanging, simply by operating keys on the learning remote control transmitter. Is what you do.

Means for Solving the Problems To solve the above problems, a key number table area, a data number table area and a data storage area are provided in a memory means of the learning remote control transmitter of the present invention, and the microprocessor means is compressed. When codes are sequentially registered in the data storage area, the registration start addresses of the registered storage data are sequentially stored in the data number table area, and the data numbers of the data number table area are stored in the key number table area corresponding to the key input section. Remember
The editing of remote control data between learning keys is enabled by performing editing operations such as moving, copying, and deleting data in the registration area of the memory means set for each learning key of the key input unit. is there.

According to the present invention, the key input section of the learning remote control transmitter is provided with editing keys for exchange, movement, copying, etc., and the memory means is provided with a key number table area, a data number table area and a data storage area. When the means sequentially registers the compressed codes in the data storage area, the registration start addresses of the registered storage data are sequentially stored in the data number table area, and the data number table is stored in the key number table area corresponding to the key input section. By storing the data numbers of the areas, editing operations such as moving, exchanging, and copying remote control data of learned keys can be easily performed, and when deleting remote control data registered in a learning key, a conventional method is used. , The registered remote control signal data itself was deleted,
According to the present invention, the remote control code can be deleted simply by changing the valid bits of the table area of the memory means. Also, remote control data with different amounts of memory registered for each key can be easily edited by using the table area in the memory.
Also, a multi-command key that outputs a continuous remote control signal by one key operation can be freely used as a multi-command key by using the table area. Also, there is an effect that the function of the multi-command key can be assigned.

Embodiment FIG. 1 explains the configuration and operation of a learning remote control transmitter with reference to FIG. 1 to FIG. In FIG. 1, 1
Is an emulated remote control transmitter. The light-emitting unit 2 of the remote control transmitter 1 is arranged to face the PIN diode 12 of the learning remote control transmitter 11 of the present invention, and the mode changeover switch 25 of the learning remote control transmitter 11 is set to the normal mode 26 (this learning remote control transmitter 11). When the learning key 34 of the key input section 24 of the learning remote control transmitter 11 is pressed, the learning mode is changed from the mode in which the learned predetermined remote control signal is transmitted to the learning mode 27 (the specific learning key 34 of the key input section 24 of the learning remote controller Mode to learn the signal of the remote control transmitter 1 you want to rate)
The display circuit 21 confirms that the learning remote control transmitter 11 has entered the learning mode 27. Of course, the learning remote controller transmitter 11 has copy, move, delete, etc. editing keys 33 for instructing the remote controller data editing operation of the present invention.
Also have.

After that, the key 3 of the remote control transmitter 1 to be emulated is pressed to transmit the optical signal 4 from the light emitting unit 2.

The transmitted optical signal 4 is the PIN of the learning remote control transmitter 11.
Received by the diode 12.

The PIN diode 12 is a photoelectric conversion element that converts the optical signal 4 from the remote control transmitter 1 to be emulated during the learning mode into an electric signal. The converted electric signal faithfully amplifies the input signal. The signal is sent to the preamplifier unit 13.

The signal output from the preamplifier 13 is divided into a frequency circuit 14 and a waveform shaping circuit 17, which are the next circuits.

First, the frequency circuit 14 is a circuit that measures the frequency of a pulse in each burst of a pulse group (hereinafter referred to as a carrier frequency as in the prior art) by the frequency counter 15 inside the frequency circuit 14 in the learning mode. Is a basic clock generation circuit 23 for driving the microprocessor 20
The carrier frequency is measured by measuring the number of clocks output from the. Further, in the normal mode, when the learning key 34 of the learning remote control transmitter 11 is pressed, the carrier frequency is generated simply by setting the value of the carrier frequency measured and stored in the learning mode to the frequency counter 15. .

In the frequency circuit 14, in the learning mode, the preamplifier 13
The carrier frequency of the remote control signal output from is measured, and the carrier frequency is output to the latch circuit 16 and latched simultaneously with the completion of the measurement.

The remote control signal output from the preamplifier 13 enters a waveform shaping circuit 17 which extracts the envelope curve of the remote control signal, which is another circuit. Its waveform shaping circuit 17
Is a pulse signal from which the carrier frequency component of the remote control signal has been removed, enters the counter 19 of the next pulse width circuit 18, and has a pulse width T1H, T1 shown in FIG.
L, T2H, T2L, T3H, T3L ... are measured in order and each pulse width 2
As shown in FIG. 2B, the data is stored in a random access memory 22 (hereinafter referred to as an SRAM) in units of bytes.

Next, a method of measuring the pulse width of the remote control signal will be described with reference to FIGS. 2 (A) and 2 (B). A change in the envelope curve input of the remote control signal, that is, the rising edge of the pulse of the remote control signal is detected, and an interrupt 28 is issued to the microprocessor 20. After that, immediately start counting the number of divided clocks (in this case, divided by 16) obtained by dividing the clock output from the basic clock generating circuit 23 that drives the microprocessor 20 by the dividing circuit 29. Then, measurement of the pulse width T1H is started. That is, “pulse width = count number of clock”. Then, an interrupt 28 is again applied to the microprocessor 20 at the same time as the falling of the pulse. Immediately thereafter, the microprocessor 20 stops counting the divided clock and immediately transfers the measured pulse width T1H data to the SRA.
The data is sequentially fetched and stored in the work area of M22 having a capacity of about 500 bytes (counter value storage). or,
Immediately, the data of the counter 19 of the pulse width circuit 18 is cleared (counter clear), and the counting of the next pulse width T1L is started. The microprocessor 20 waits for time until the next rise of the pulse width T2H, or performs another job. At the next rising edge of the pulse width T2H, the counting is stopped, and the data of the pulse width T1L of the envelope curve is taken into the work area of the SRAM 22 in the same manner as described above (counter value storage). In this manner, counting is performed until the work area of the SRAM 22 is full, and the work of storing the count is continued. At the same time as the end, the data of the carrier frequency measured by the frequency circuit 14 is taken into a predetermined area of the SRAM 22. This completes the capture of data from the remote control transmitter to be emulated.

Next, the compression of the data taken into the work area of the SRAM 22 will be described. In the compression, the pulse trains constituting the data of the taken remote control code are classified into two groups.
The pulse train composed of bytes is replaced with a pulse number composed of 4 bits, and is changed to remote control data encoded by the classification of the pulse train.

Subsequent compression is then performed by further compressing the data for each key, and this compression is also a process of omitting repeated codes in the remote control code.

By this operation, a repetition code is omitted and a pulse train composed of about several tens of bytes is compressed.

In this way, the emulated remote control signal stored in the work area of about 500 bytes in the SRAM 22 includes the data number, carrier frequency data, pulse width data, pulse number type, single-shot signal or continuous signal. The repetition is converted into compressed data such as from what pulse number.

The compressed remote control data is stored in an SRAM 22, which is composed of three blocks, a table area, a storage area, and a work area, as shown in FIG. Each of the compressed remote control data is sequentially stored and registered as storage data in an empty area of a storage area of the SRAM 22, which is a collection of compressed remote control data. Then, the compressed remote control data, that is, the stored data is registered in the key number learned this time in the table area in which the registration start address of the compressed remote control data corresponding to the key number of the SRAM 22 is registered. SRAM22
The registration start address is registered. In addition, a memory area for temporarily storing a registration start address necessary for editing operations such as movement and exchange (this area is called a temporary area and a work area may be used instead) is provided. Has an editing key 33 for instructing editing such as copy, exchange, deletion, and resurrection.

In addition, an area may be provided in the table address for storing editing data necessary for editing (for example, a valid bit indicating whether the head address of the storage data registered in the key number is valid).

Next, how to edit the remote control data registered in each learning key 34 will be described. As an example, the key input unit 24
The case of exchanging remote control data of keys 1 and 2 will be described.

In this embodiment, the present invention can be implemented by exchanging the registration start address registered in the key number corresponding to the key of the key input unit 24. If a person wants to exchange data between key 1 and key 2 of the key input unit of the learning remote control transmitter 11 that has learned the remote control code, the editing key 33 in the learning remote control transmitter 11 Press the exchange key first. Then, the microprocessor means 20
Reserves temporary for exchange. Next, when the key 1 to be exchanged is pressed, the registration start address of the key number 1 is temporarily copied. Next, when key 2 is pressed, the registration start address of key number 2 is changed to key number 1
Is copied to the table area. This time, the data of key number 1 that has been temporarily stored is copied to the table area of key number 2. Now key 1
And the data exchange of key 2 is completed. Thus, by directly changing the registration start address of the key number, the other edit keys 33 can be changed in the same manner as described above.

Next, an embodiment according to the present invention will be described with reference to FIG. 4. The configuration of a learning remote control transmitter is the same as that of the above embodiment, but a major difference between this embodiment and the method of registering data in a memory is shown in FIG. The only difference is. First, how to register this data will be described. The SRAM 22 is divided into five blocks of a work area, a multi-command key registration area, a data storage area, a data number table area, and a key number table area. As shown in the SRAM map of FIG. The data is sequentially stored and registered in the SRAM 22 data storage area as storage data, and the compressed remote control data, that is, the storage data is sequentially registered in the data number in the data number table area of the SRAM 22. The registration start address of the SRAM 22 is registered. The relationship between the key of the key input section 24 and the remote control code is completed by registering the data number of the data number table area with the learned key number in the key number table area. With such a configuration, the editing of the registered remote control data can be easily performed only by changing the relationship between the key number and the data number.

Next, how to edit the registered data will be described.

For example, when exchanging the remote control data of the key 1 and the key 2 of the key input unit 24, it can be realized by exchanging the data numbers registered in the key numbers of the key number table area. If the operator wants to exchange the data of key 1 and key 2 of the learning remote control transmitter 11 having learned the remote control code, the learning remote control transmitter
First, the exchange key in the 11 edit keys 33 is pressed.
Then, the microprocessor means 20 secures a temporary area for replacement in the SRAM 22. Next, when the key 1 to be exchanged is pressed, the data number registered in the key number 1 is temporarily copied. Next, when key 2 is pressed, the data number of key number 2 is copied to the data area of key number 1. Then, the data number of key number 1 which has been temporarily stored until now is copied to the data area of key number 2. This completes the data exchange between the key 1 and the key 2. In this way, by indirectly changing the registration start address of the stored data, the other edit keys can be similarly changed.

Also, a multi-command key that outputs a plurality of remote control codes by one key operation is also set to a preset data number indicating that it is a multi-command key. If there is, simply registering... As a key number will determine that the key number is a multi-command key. For the data number “FF”, a registration area is secured as a multi-command key area so that key numbers constituting a multi-command can be stored. By storing the key numbers in the registration area in the order of transmission, a multi-command key can be freely set to any key and can be easily changed. In order to increase the number of multi-command keys, the number is increased by increasing a preset data number.

In addition, by using the valid bit provided in the above-described embodiment in the table area, the remote control data itself is deleted by deleting the remote control data. It is possible to add the function that the original remote control data can be restored by enabling the valid bit using the resurrection key if the data has the same effect as deleting the data and deleting it by mistake. Become. In this case, the remote control data is lost as an entity when another remote control data is registered to the key.

Further, by creating other editing data, various functions can be increased, and editing can be performed easily.

Advantageous Effects of the Invention As is clear from the above embodiment, the present invention requires a learning operation to be performed from the beginning of a key to be moved when a key between remote control codes registered in the key is moved after learning. The remote control transmitter requires an emulated remote control transmitter, and the new remote control device allows the remote control code to be registered, changed, deleted, newly registered, etc. Up to now, the emulated remote controller transmitter had to be aligned and learned and changed from the beginning, but the key number table area and data were stored in the memory means of the learning remote controller. A number table area and a data storage area are provided. When the microprocessor means sequentially registers the compressed codes in the data storage area, the registered information is stored. The registration start address of the memory data is sequentially stored in the data number table area, and the data number of the data number table area is stored in the key number table area corresponding to the key input section, so that the data is registered in the key of the learning remote control transmitter. Remote control data can be easily changed and moved, and editing between remote control keys such as delete and restore functions can be performed. Also has an effect that a multi-command key can be set.
