Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control device suitable for use in a video tape recorder or the like.

[Prior Art] Conventionally, video tape recorders (VTRs) have been equipped with a remote control function in order to make them easier to use. It is possible to operate.

In such a remote control transmitter, each operation button provided on the transmitter has one function, and when one of the operation buttons is pressed, data with a code representing the assigned function is generated and transmitted to the VTR. sent to. The VTR receives and decodes this data and performs the function represented by this data.

By the way, in conventional remote control transmitters, the data that is generated and transmitted is determined, and although it is possible to change the function assignment for each operation button, Of course, it cannot be used for VTRs, and it cannot be used for other products such as video disc players.For this reason,
Each product required a remote control transmitter.

To solve this problem, Japanese Patent Application Laid-Open No. 61-234
In Publication No. 99, a means for storing data is provided,
A remote control in which necessary data is sent from the outside and stored in this storage means in correspondence with a predetermined operation button, and when the operation button is pressed, the corresponding data is read out and transmitted. A transmitter has been proposed.

Such a remote control transmitter has a receiving function, and another remote control transmitter whose operation buttons and data have already been corresponded is used as the transmitting side, and the function consisting of the remote control transmitter on the transmitting side is By transmitting the data representing the data, putting the proposed remote control transmitter in the receiving state, and pressing a predetermined operation button,
This operation button is activated in response to the received code.

In this way, one remote control transmitter can be used for multiple different products.

[The problem that the invention tries to solve! [9i] However, in the conventional remote control transmitter described above, although it is a transmitter, it needs to have a receiving function and a device for this is required. A high-capacity microprocessor and a large-scale program are required to analyze and decode the data, and write and read this data in a storage means.Furthermore, an E2FROM for data storage is required.
This also requires a power source such as a lithium battery for backup, which inevitably makes the remote control transmitter large and expensive.

Furthermore, the conventional remote control transmitter described above merely stores data representing a single function from the transmitting side remote control transmitter, and is capable of retransmitting this data as necessary. There was a problem in that it was not possible to add functions desired by the user.

An object of the present invention is to solve such problems, suppress the increase in size and high cost of the remote control transmitter, and enable remote control using any remote control transmitter with different transmission methods. An object of the present invention is to provide a remote control device capable of executing a series of a plurality of functions with a single operation.

[Means for Solving the Problems] In order to achieve the above object, the present invention receives a remote control signal transmitted from a remote control transmitter by operating its operation button, and extracts compressed data from the remote control signal. A first means for generating and storing the compressed data, and a second means for storing control information representing an operation mode of a device to be remotely controlled in correspondence with the stored compressed data are provided.

[The action control information is generated in response to the operation of an operation button for setting the operation provided on the device, the detection operation of the detection means, etc. When the control information is stored in the means of the second means in correspondence with the compressed data stored in the first means, the operation button of the remote control transmitter that has generated the compressed data by operation is pressed to release the compressed data. It functions as an instruction button for the operation mode represented by the control information stored in the second means corresponding to the data.

Therefore, when this operation button is operated to remotely control the above device, the corresponding control information is read from the second means using the compressed data generated by this, and the mode corresponding to this control information is set. The above equipment works.

In this way, since the operation buttons of the remote control transmitter are functionalized, the device can be remotely controlled regardless of the transmission method.

Furthermore, a single piece of compressed data can be associated with a plurality of pieces of control information, so that a single operation of the remote control transmitter can cause the device to perform a series of different operations.

[Example] Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a remote control device according to the present invention, in which 1 is a remote control transmitter, LA, IB, and IC are operation buttons, 2 is a remote control signal receiving section, and 3 is a microprocessor. , 4 is a data compression section, 5 is a storage section, 6A to 6C are compressed data storage sections, 7A to 7B are control information storage sections, 8A to 8C are operation buttons, 9 is a mode switching button, 10 is a controlled section, 11 1 is a tape end detector, 12 is a tape start end detector, and 13 is an object to be controlled.

In this figure, a device remotely controlled by operation of the remote control transmitter 1 is shown as V.
The illustrated parts other than the remote control transmitter 1, such as a remote control signal receiving section 2, a microprocessor 3, and a controlled section 10, are provided in this VTR. Operation buttons 8A to 8C and mode switching button 9 are VT.
It is provided on the front panel (not shown) of R, and information corresponding to these operations is supplied to the microprocessor 3. Here, the operation button 8A is a stop button, the operation button 8B is a playback button, and the operation button 8C is a record button. Buttons for other operating functions have been omitted.

Mode switching button 9 is used to select between normal mode and storage mode. As a result, when the normal mode is selected, the VTR performs operations corresponding to the operations of the operation buttons 8A to 8C. That is, if the operation (record) button 8C is operated now, this is the microprocessor 3.
control information representing recording is generated and supplied to the controlled unit 10 as a recording command. The controlled unit 10 is.

This recording command controls a controlled object 13 such as a capstan motor or a cylinder motor to execute a recording operation.

During recording, when the tape end detector 11 detects the end of the magnetic tape (not shown), the controlled unit 10 automatically rewinds the magnetic tape in response to this detection output, and also detects the beginning of the tape during this rewinding. When $12 detects the starting end of the magnetic tape, it automatically stops the magnetic tape in response to this detection output.

The microprocessor 3 is provided with a storage unit 5, and the storage unit 5 stores each operation button LA,
IB and IC are associated with the operation of a VTR, and below,
A method for making this correspondence will be explained. In addition, in order to simplify the explanation, each control information is expressed as follows.

The control information from the operation (record) button 8C is re 1 tt The control information from the operation (playback) button 8B is '2' The control information when the tape end detector 11 detects the end of the tape is '3' Tape start end detector 12 The control information obtained by detecting the beginning of the tape is 4n (1) First, we will explain the case where the operation button IA of the remote control transmitter 1 corresponds to one operation mode of the VTR. do.

First, the mode switching button 9 is operated to set the microprocessor 3 to the storage mode, and the operation button IA of the remote control transmitter 1 is operated. As a result, the remote control transmitter 1 transmits a remote control signal of data representing the operation of the operation button IA.

The remote control receiver 2 receives this remote control signal and supplies it to the microprocessor 3. In the microprocessor 3, this remote control signal is stored in the storage unit 5, but if the remote control signal were stored in its waveform, the amount of information would be extremely large, so the storage unit 5 would have to have a large capacity. Is required.

For this purpose, this remote control signal is compressed by the data compression section 4, and the compressed data obtained thereby is stored in the storage section 5.

By the way, the 1.0-bit waveform of the remote control signal transmitted by the remote control transmitter 1 varies depending on the type of device being remotely controlled or due to differences in the transmission method depending on the manufacturer of the device even if the device is of the same type. , different from each other.

For this reason, it is difficult to accurately reproduce data consisting of 1.0 bit from the received remote control signal. For this purpose, the data compression unit 4 captures the waveform characteristics of the received remote control signal and
From this, 1 and 0 bits are defined and 1 and 0 bit data corresponding to the waveform of this remote control signal is generated.

For example, if a remote control signal having the waveform shown in FIG. Every T4, a waveform is detected based on a count value between edges by an internal timer of the clock shown in FIG. 2(a), and data is generated by making the difference in waveform correspond to 1.0 bit. Second
According to the waveform shown in Figure (b), period T1. In T2,
L from its starting falling edge to its next rising edge
Yo.

The L2 period count value is 2, H1 from this rising edge to the final falling edge, and the count value 16 of the H2 period is 4. On the other hand, in the period T3°T4, from the starting falling edge to the next rising edge,
, the count value for the L4 period is 2, and the count value for the H3 and H4 periods from this rising edge to the final falling edge is also 2. In this way, T, , T2 period and T, ,
The waveforms in the T4 period are different, and this shows that the waveforms in the T1.
The waveform for the T2 period is defined as 1 bit, and the waveform for the T, , T4 periods is defined as O bits. As a result, the received remote control signal is converted into 1100 4-bit compressed data.

The compressed data generated by the data compression unit 4 in this manner is supplied to the storage unit 5, and is written to an empty portion of the compressed data storage units 6A to 6C, for example, the compressed data 6A.

Here, in the storage section 5, the compressed data storage section 6A and the control information storage section 7A correspond to each other, and similarly, the compressed data storage sections 6B and 6C correspond to the control information storage sections 7B and 7C, respectively. .

Next, when the operation (recording) button 8C is operated, the microprocessor 3 generates recording control information +r 1 tt, and the compressed data storage unit 6 in which the previous 1100 compressed data is stored.
Write to the control information storage section 7A corresponding to A.

As a result, the operation button I of the remote control transmitter 1
A is made to function as a recording button, and in the same manner, each operation button IB and IC of the remote control transmitter 1 can be made to function.

After activating the desired operation buttons of the remote control transmitter 1 in this way, when the mode switching button 9 is operated to switch to the normal mode, the remote control transmitter 1 can remotely control the VTR. That is, when the operation button IA functioning as a recording button of the remote control transmitter 1 is operated, a remote control signal resulting from the operation is received by the remote control signal receiving section 2 and supplied to the microprocessor 3.
The data compression unit 4 generates 1100 pieces of compressed data using the method described above. Then, it is checked that the same compressed data as this compressed data is stored in the compressed data storage section 6A, and the corresponding control information "'1" stored in the control information storage section 7A is read out. , is supplied to the controlled unit 1o as a recording command.Thereby, the controlled unit 1o
The state is the same as when the operation (recording) button 8C is operated, and the VTR is set to recording mode.

(2) Next, a case will be described in which a desired operation button of the remote control transmitter 1 is made to correspond to a series of a plurality of operation modes of the VTR. Here, this series of operating modes starts recording, then automatically rewinds when the end of the magnetic tape is detected, and automatically starts playback when the start of the magnetic tape is detected. It is assumed that this operation consists of a composite operation and is associated with one operation button IB of the remote control transmitter 1.

As in the case (1) above, first operate the mode switching button 9 to set the memory mode, and then use the remote control transmitter 1.
Operate operation button IB. The resulting remote control signal is received by the remote control signal receiving section 2 and supplied to the microprocessor 3, and the data compressing section 4 generates compressed data of, for example, 1101 as described above.

This compressed data is supplied to the storage section 5, and assuming that the above 1100 compressed data is currently stored in the compressed data storage section 6A, it is written to the next compressed data storage section 6B.

Next, the operation (recording) button 8C is operated, whereby the microprocessor 3 generates recording control information 1/I II and writes it into the control information storage section 7B corresponding to the compressed data storage section 6B of the storage section 5. At the same time, a recording command is sent to the controlled unit 10. As a result, the VTR starts recording.

Thereafter, when the tape end detector 11 detects the end of the magnetic tape, the controlled unit 10 switches to the rewind mode and rewinds the magnetic tape.At the same time, the tape end detector 11 detects the end of the magnetic tape. Control information "3" indicating that it has been detected is sent to the microprocessor 3.

In the microprocessor 3, this control information rt 3 u is written into the control information storage section 7B of the storage section 5.

Thereafter, when the tape start edge detector 12 detects the start edge of the magnetic tape, the controlled unit 1o stops the magnetic tape and enters the stop mode.At the same time, the tape start edge detector 12
Control information 11 indicating that the start end of the magnetic tape has been detected.
4 Send PI to microprocessor 3. In the microprocessor 3, this control information It 4 IT is written into the control information storage section 7B of the storage section 5. When the magnetic tape stops and the operation (playback) button 8B is operated, the microprocessor 3 generates playback control information "2",
It is written in the control information storage section 7B of the storage section 5 and also sends a reproduction command to the controlled section 10. As a result, the VTR starts playing.

When the series of operations is completed in this way and the mode switching button 9 is operated to switch to the normal mode, the operation button IB of the remote control transmitter 1 is made to function as an operation button for performing the above series of operations.

Therefore, when this operation button IB is operated after that, compressed data of 1101 is generated in the data compression section 4 of the microprocessor 3, and based on this compressed data, 1101 of the data of the recording section 5 is generated.
Compressed data storage unit 6 in which compressed data of 01 is stored
B is retrieved and the corresponding control information u I II “3 II LL 471 is retrieved from the control information storage unit 7B.
, 142 # are read out sequentially. Then, the microprocessor 3 sends the control information "1" to the controlled unit 10 as a recording command, and causes the VTR to start recording. Thereafter, when the tape end detector 11 detects the end of the magnetic tape, the controlled unit 10 starts rewinding the magnetic tape and sends control information "3" to the microprocessor 3. The microprocessor 3 recognizes that the magnetic tape is being rewound by comparing the sent control information "3" with the control information "3" read from the control information storage section 7B. Next, when the tape start end detector 12 detects the start end of the magnetic tape, the controlled unit 10 stops the magnetic tape and sends control information "4" to the microprocessor 3.
” Send.

As a result, as in the case of control information 113)l, the microprocessor 3 recognizes that the magnetic tape has been rewound to the starting end and has stopped, and immediately sends the control information "2" to the controlled unit 10 as a reproduction command. send. This allows the VTR
starts playing.

As described above, in this embodiment, each operation button of the remote control transmitter is used to set the operation mode of the remotely controlled device (VTR), and the operation mode of the device (VTR) is controlled by one operation of the one operation button. It also becomes possible to execute a desired series of composite operations.

By the way, in this embodiment, when one operation button of the remote control transmitter is made to function as a composite operation of the VTR, the VTR is made to perform the composite operation, and therefore, it takes a long time to perform the function operation. FIG. 3 is a block diagram showing an embodiment of a remote control device according to the present invention that improves this point, in which 14 is a storage section, 15
16 is a selection button, 16 is a setting display section, and parts corresponding to those in FIG. 1 are given the same reference numerals.
Not only control information generated by operating the operation buttons for setting the operation mode such as C, but also control information generated by means other than the above operation buttons, such as control information representing tape end and start edge detection generated by the controlled section 1°, is generated. do. Control information other than the operation of these operation buttons is generated in order every time the selection button 15 is operated, and which control information is generated is displayed on the setting display section 16. The storage unit 14 stores control information generated by operating the selection button 15 in control information storage units 7A to 7.
This is an operation button for writing to C.

When you operate the mode selector switch 9 to enter the memory mode,
The microcomputer 3 causes, for example, the word "MEMORY" to blink on a part of the screen of the setting display section 16 to indicate that the device is in the storage mode. In this state, press operation button 8.
When any of A to 8c operates, for example, the operation (recording) button 8c, the microcomputer 3 generates recording control information tr I J+ and stores it in the storage unit 5, similarly to the embodiment shown in FIG. The control information is stored in one of the control information storage sections 7A to 7c, and at the same time, the setting display section 16 displays in text or the like that the control information "1" has been generated.

The operation of this embodiment will be explained below, but the operation method when the operation buttons IA to IC of the remote control transmitter 1 function only in one operation mode of the VTR is the same as in the embodiment shown in FIG. Therefore, we will explain how to operate the composite operation mode.

Here, recording is started, and then when the end of the magnetic tape is detected, rewinding is automatically performed, and when the beginning of the magnetic tape is detected, playback is automatically started. When operating the operation button IB of the remote control transmitter 1 in the operation mode, first operate the mode switching button 9 to set the storage mode, and then operate the operation button IB of the remote control transmitter 1. Due to this.

Similar to the embodiment shown in FIG. 1, in the microprocessor 3, compressed data, for example 1101, corresponding to the operation of the operation button IB is generated in the data compression section 4, and is stored in the compressed data storage section 6B of the storage section 5, for example. written. After that,
When the operation (recording) button 8c is operated, recording control information 1 (IN) is generated in the microprocessor 3 and stored in the compressed data storage section 6B in the storage section 5, as in the embodiment shown in FIG. It is written into the corresponding control information storage section 7B.

Although the setting display unit 16 displays that the control information “1n” has been generated, writing of the control information to the control information storage units 7A to 7C is performed by operating the storage unit 14. This makes it possible to check whether the correct operation button among the operation buttons 8A to 8C has been operated and to correct the operation.

In this way, the control information it 1 is stored in the control information storage section 7B.
When pp is written, control information 1 (3j+), which is the same as that generated when the controlled unit 10 detects the end of the tape by the tape end detector 11 in the microprocessor 3, is generated, and this is displayed in the setting display unit 16. Continue operating the selection button 15 until .

When this display is made, the generated IIJ control information "3" is written into the control information storage section 7B of the storage section 5 by operating the storage section 14. Next, the selection button 15 is operated again, and in the same way, the microprocessor 3 selects the controlled unit 1.
By causing the same control information II 411 that is generated when 0 detects the tape start edge by the tape start edge detector 12 and then operating the storage unit 14, the generated control information LL 4 II is written into the control information storage section 7B of the storage section 5. Next, when the operation (playback) button 8B is operated, the microprocessor 3 outputs the playback control information it2, similar to the embodiment shown in FIG.
y+ is generated and stored in the control information storage section 7B of the storage section 5.

In this way, similarly to the embodiment shown in FIG. 1, the operation button IB of the remote control transmitter 1 is made to function in the above-mentioned composite operation mode.

FIG. 4 is a block diagram showing still another embodiment of the remote control device according to the present invention, in which 17 is an external storage section, and parts corresponding to those in FIG. 1 are given the same reference numerals.

In this embodiment, as shown in FIG. 4, the microprocessor 3 is provided with an external storage section 17 in which compressed data and control information of the remote control signal from the remote control transmitter 1 are stored. Operation button 8A~
8C, a mode switching button 9, etc. are connected to the controlled unit 10 side, and when the mode switching button 9 is in the storage mode, the controlled unit 10 generates various control information and supplies it to the microprocessor. This embodiment differs from the embodiments shown in FIGS. 1 and 3 only in this respect, but the other configurations, operations, and effects are the same.

Note that in the embodiment shown in FIG. 1, as shown in FIG. A setting display section 16 is provided.

When the operation buttons of the remote control transmitter 1 are made functional using these, the operations of the operation buttons 8A to 8C, etc. may be confirmed and corrected.

Furthermore, in each of the embodiments described above, the microprocessor 3 and the external storage section 17 may be those that are already provided.

[Effects of the Invention] As explained above, according to the present invention, even remote control transmitters of other models or products of other companies using different transmission methods can be remotely controlled without having a microprocessor or receiving function. As the remote control transmitter is inexpensive, small and easy to handle, it can be shared for remote control of other models or products of other companies, and the remote control transmitter has a single operation button. Not only can a single operation mode be implemented, but also a composite operation mode consisting of a desired series of operations can be implemented, greatly improving usability for the user.
