The present invention relates to a remote control device that can be operated with a small number of operations.

[0002]

2. Description of the Related Art Generally, in electronic equipment such as VTRs and TVs,
From a position away from these electronic device main body, its operation,
There is a remote control device that can control the function. This remote control device
It is equipped with a hand unit provided with operation keys for each control item, and by operating the operation keys, for example, a remote control signal modulated using infrared light as a medium is transmitted toward the electronic device body, and the electronic device body Upon receiving the remote control signal, the corresponding control item is controlled.

As control items by the remote control device, for example, in a VTR, in addition to basic operations such as power on / off, recording, reproduction, pause, stop, fast forward, and rewind, a built-in tuner is used. Channel selection, recording timer settings, etc. The TV has control items such as power on / off, channel selection, volume adjustment, color adjustment, and selection of whether to receive an input signal via a tuner or an external input terminal.

In a normal use state in which a VTR and a TV are combined, a signal reproduced by the VTR is set to be viewed on the TV. The VTR sends the reproduced signal to the TV as a high frequency signal having a TV channel frequency. In the VTR, the channel of the high frequency signal to be supplied to the TV is set before the power is turned on and the reproducing operation is performed. On the TV side, the channel is selected by the channel selection key of the remote control device so as to correspond to the output signal frequency of the VTR, or the input switching key is set to receive the signal supplied from the VTR in the baseband. It

As described above, in the electronic equipment, the functions are diversified and the items that can be controlled by the remote control are increasing, and the key operation of the hand unit is becoming complicated. It may be necessary to set a plurality of different control items before the device is controlled to reach a desired operating state, and the user must perform many key operations on the hand unit.

[0006] In particular, in a device such as a VTR and a TV that uses a combination of a plurality of devices, the control method is specified or the procedure for performing the intended control changes depending on the operating state of the other party. In some cases, the operation becomes more complicated.

Therefore, it is desired to realize a remote control device capable of performing a desired control with a simpler operation. For example, an attempt has been made to make a hand unit common to a VTR and a TV. Since each is executed with a different key, it is not so effective in terms of simplifying the operation.

It is apparent that the efficiency can be remarkably improved by sequentially controlling a plurality of related items by using a single operation key, and a remote control device as shown in FIG. 6 is conceivable. .

In the remote control device shown in FIG. 6, the key input means 1 is composed of a key input operation unit such as a ten-key pad. Here, the key input signal 11 is output by a key input operation by a specific key. If the specific key of the key input means 1 is operated, the key input signal 11 is supplied to the transmission code creating means 2, the time counting means 6 and the order counting means 7.

The transmission code creating means 2 uses the key input signal 1
Whenever 1 is input, the transmission code 41 is read from the transmission code table storage means 4 each time. The transmission code table storage unit 4 is, for example, a storage circuit that stores a transmission code table of a plurality of control items for a single electronic device or a plurality of electronic devices. The transmission code table is stored in a predetermined address order. It is composed of a plurality of transmitted codes.

The transmission code creating means 2 reads the transmission code from the transmission code table storage means 4 in correspondence with the count data 71 from the order counting means 7, and supplies the read transmission code 41 to the transmission means 5. .

The transmitting means 5 modulates the transmission code 41 to create a remote control signal and transmits it to a receiving device (not shown) such as an electronic device.

The order counting means 7 counts the number of key operations based on the key input signal 11. The count data 71 sets the read address of the transmission code table storage means 4 and every time the key is operated. Then, the transmission codes are sequentially read from the transmission code table storage means 4. Further, it is configured to return to the initial value when the count number reaches a predetermined value. Further, the order counting means 7 is set to an initial state by a reset signal 21 from the transmission code creating means 2, and the reset signal 21 is generated when a key other than a specific key is operated or by a signal from the clock counting means 6. To be done.

Transmission code 4 supplied to the transmission means 5
1 is frequency-modulated by the transmitting means 5 using, for example, infrared rays, and is transmitted from the light emitting diode as a remote control signal.

On the other hand, the time counting means 6 initializes the time count value and starts counting when the key input signal 11 from the key input means 1 is supplied. Here, for example, a time of 30 seconds. When elapses, a signal 61 is output to the transmission code creating means 2 to request the order counting means 7 to be reset.

Such a remote control device is
When used to control the output signal form of the VTR and the receiving form of the TV, for example, every time a specific key such as a standby key (hereinafter referred to as STANDBY key) is operated, the control shown in the flowchart of FIG. 7 is performed. You can

That is, first, the count of the time counting means 6 shown in FIG. 6 is stopped and set to t = 0 (step 71), and then the count value n of the order counting means 7 is set to 0 (step 72). . Next, it is determined whether or not the STANDBY key has been operated (step 73), and the count value of the order counting means 7 is incremented by 1 by the first key operation to become 1 (step 74), and at the same time, the time counting means 6 becomes 0. To start counting (step 75). When it is determined that the count value of the sequence counting means 7 has become 1 (step 76), the power of the VTR is turned on and at the same time T
A code for setting the receiving channel of V to 1 is transmitted (step 77). At the same time, the VTR outputs a video signal for confirmation, for example, a character signal such as "STANDBY". Here, if the power of the TV is on and the output of the VTR is the signal form of channel 1, "S" appears on the TV screen.
TANDBY "is displayed, and the operation ends here.
When the count value t of the time counting means 6 becomes larger than the predetermined value T, it is judged (step 83), and the count values of the time counting means 6 and the order counting means 7 are reset to zero. Alternatively, when another key is operated to determine it (step 84) and the corresponding code is transmitted, the count values of the time counting means 6 and the order counting means 7 are reset to zero.

If "STANDBY" is not displayed,
When the second key operation is performed, the count value of the order counting means 7 becomes 2 by the operation, and it is determined (step 78) that the code for changing the TV channel to 2 is transmitted. (Step 79). At the same time, a video signal for confirmation is output from the VTR. "STANDBY"
If no display is made, the TV is switched to receive the external input signal by the third key operation (steps 80, 8).
1) At the same time, a video signal for confirmation is output from the VTR. Here, if "STANDBY" is not displayed, it is determined that the power supply of the TV is off, the power supply of the TV is switched by the fourth operation, and the process returns to the beginning again to perform the same control (step 82).

Therefore, in this case, the target setting is made by operating the specific key a maximum of seven times.

However, in the remote control device having such a configuration, the intended control can be performed by operating a single specific key, but the count data 71 and the transmission code 41 have a one-to-one relationship, and the control is performed. Since the processing routine is started from the initial state every time it is needed, there is a disadvantage that the key operation must always be performed a maximum of seven times.

[0021]

As described above, in the remote control device, the target control can be performed only by operating a single specific key, but the number of key operations is increased and the target control is performed. There was a problem of poor operability.

In view of the above problems, the present invention is directed to a remote control device for controlling a plurality of control items by operating a single specific key, thereby reducing the number of key operations and achieving a desired control with a simple operation. An object is to provide a remote control device that can be operated.

EXAMPLES Examples will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a remote control device according to the present invention, and elements similar to the constituent elements shown in FIG. 6 are designated by the same reference numerals.

In FIG. 1, the key input means 1 outputs a key input signal 11 each time the user operates a key using the same key. For example, "STANDBY" in the hand unit 10 shown in FIG. When the key 300 of the key input means 1 is operated including the key 300, the key input signal 11 is supplied to the transmission code creating means 2, the time counting means 6 and the order counting means 7.

The transmission code creating means 2 uses the key input signal 1
When 1 is input, the table selection data 31 stored in the storage 3 is read from the table selection data storage 3.

The table selection data 31 is data for selecting a corresponding transmission code table from a plurality of transmission code tables stored in the transmission code table storage means 4, and the key input signal 11 is input to generate a code. Each time it is transmitted, the data corresponding to the transmission code is stored. In the initial operation of the remote control device, predetermined table selection data is stored.

The transmission code table storage means 4 stores, for example, a plurality of transmission code tables each composed of a plurality of transmission codes. In each transmission code table, predetermined transmission codes are transmitted in a predetermined order. Are arranged as follows. When the key input signal 11 is input to the transmission code creating means 2, the transmission code creating means 2 selects one of the transmission code tables based on the table selection data 31 from the table selection data storage means 3.

In the example shown in FIG. 4, the transmission code table storage means 4 has three transmission code tables with table numbers 1-3. Here, the function of each transmission code will be explained. "TV 1CH" is a transmission code that makes the receiving channel of TV 1 channel, and "TV 2CH" is T
"TV VIDEO" is a TV code, which is a transmission code that converts V into 2 channels
"TV POWER" is a transmission code for turning on / off the power of the TV, and "VTR ON" is a transmission code for turning on the power of the VTR. In FIG. 4, table selection data is shown in parentheses, and the numeral is the table number to be selected.

The sequence counting means 7 is set to a count of zero in the initial state, receives a specific key input signal from the key input means 1, counts the number of times the specific key is operated, and outputs count data 71 to the transmission code creating means 2 This count data 71 is used as data for specifying the transmission code in the selected transmission code table.

Therefore, the transmission code creating means 2
As described above, when the key input signal 11 is input, the transmission code table corresponding to the table selection data 31 is recognized from the transmission code table, and the counter by the order counting means 7 is further detected from this transmission code table. The transmission code 41 based on the data is selected, and this transmission code 41 is supplied to the transmission means 5.

The transmitting means 5 is the transmission code creating means 2
The transmission code 41 supplied from the device is transmitted as a remote control signal to a remote control receiving device such as another electronic device (see 818 and 825 in FIG. 5). For example, the supplied transmission code 41 is frequency-number modulated. However, the light emitting diode transmits it as a remote control signal by infrared rays, for example.

The time counting means 6 starts counting the time count value t when the key input signal 11 from the key input means 1 is supplied, and then a predetermined time T, for example, 30 seconds elapses. If the specific key is not operated until then, the table selection data update request signal 61 is output to the transmission code creating means 2, and the count value is reset to 0 to stop the counting operation. The time counting means 6 also resets the count value to 0 by the signal 22 from the transmission code creating means 2 when another key different from the specific key is operated, and simultaneously stops the counting operation.

Now, a signal supply path from the VTR to the TV will be described with reference to FIG.

The VTR 81 receives the broadcast signal supplied to the antenna terminal ANT via the cable or the antenna by the tuner 811, and outputs the video / audio signal processing circuit 812.
While converting to baseband video and audio signals and deriving to the recording / reproducing means 813, switches SW1 and SW2
Supply to. The output of SW1 is converted into a high frequency signal of the TV channel by the RF modulator 814 and is led to the RF output terminal ROUT via SW3. The output of SW2 is led to the video output terminal VOUT. The frequency of the output signal of the RF modulator 514 is switched by the frequency switching means 815 so as to correspond to, for example, one channel or two channels. In addition, the broadcast signal supplied to the antenna terminal ANT is the switch S as it is.
It can also be led to the RF output terminal ROUT via W3. Further, a specific signal source 816 is provided, and for example, “S
TANDBY "character video signal is generated.
The R81 has a power supply circuit 817 and remote control signal receiving means 818. The switches SW1 and SW2 are switched so as to derive the output of the video / audio signal processing means 812 as shown in the figure, except in the reproduction mode.

The TV 82 has an RF output terminal R of the VTR 81.
The signal output from OUT is R via the cable 819.
It is supplied to the F input terminal RIN and received by the tuner 821. The received television signal is converted into a baseband video / audio signal by the video / audio signal processing means 822, and is led to the video / audio output means 823 having, for example, a CRT and a speaker via the switch SW4 to be viewed by the user. To be done. Furthermore, a video input terminal VIN for directly receiving a baseband video / audio signal from the outside is provided, and a video output terminal VOUT of the VTR and a cable 83.
You can connect with. Further, the TV 82 has a power supply circuit 8
24 and remote control signal receiving means 825.

Next, the operation of the remote control device shown in FIG. 1 will be described with reference to the flow chart of FIG.

In the initial state, first, the table selection data storage means 3 is initialized (step 211) and predetermined initial data is stored. The initial data is, for example, data for selecting the table 1 shown in FIG. Further, in the initial state, the time counting means 6 is reset to 0 count and stops counting (step 214), and the order counting means 7 is also reset to 0 count (step 215).

If the "STANDBY" key, which is the specific key of the remote control handset 10 in FIG. 3 is operated (step 216), the count of the order counting means 7 becomes 1 (step 217), and the clock counting means 6 is further added. Is 0
To start counting (step 218). The fact that the count n of the order counting means 7 has become 1 is discriminated (step 219) and the transmission code A is transmitted (step 220). This transmission code is a transmission code that sets the TV reception channel, which is the first code in Table 1, shown in FIG. 4, to channel 1 and turns on the power of the VTR. By transmitting this code, the TV shown in FIG.
The tuner 821 of 82 is switched to receive the channel 1, and at the same time, the SW4 is turned on by the video / audio processing means 82.
It is switched to select 2 outputs. Where V
If the output of TR is a high frequency signal corresponding to one channel of TV, the signal of the specific signal source 816 is output via SW1, the RF modulator 814 and the switch SW3,
It is received by the tuner 821 of the TV, and the video / audio signal processing means 822 and the video / audio output means 823 via the SW4.
Output to the CRT screen (not shown)
The character "NDBY" is displayed. The user recognizes that no further operation of the specific key is necessary. The selection data a is stored in the table selection data storage means 3 simultaneously with the transmission of the code A. (Step 221).
The selection data a is (* 1) as shown in FIG. 4, and corresponds to the table 1 of the transmission code table storage means 4.

After that, the count t of the time counting means 6 is counted.
Is determined to be greater than T (step 2
22) Alternatively, when the operation of a key other than the specific key is recognized (step 223), the selection data a of the table selection data storage means 3 is read (step 212), and the transmission code table is changed (step 212). Step 213). In the case of the selection data a, since the table 1 of the transmission code table storage means 4 is selected, no substantial change is made, and the TV reception mode is changed to the VTR by one operation of the key input means 1 thereafter. It can be adapted to the output form of.

If the character "STANDBY" is not displayed even after the code A is transmitted in step 220, the specific key is operated again. It is determined that the count value n of the order counting means 7 has become 2.
When (step 224), the transmission code B is transmitted (step 225), and the selection data b is stored in the table selection data storage means 3 (step 226). This transmission code B is the second code in Table 1 shown in FIG. 4, and changes the TV channel to 2. As a result, when the character "STANDBY" is displayed on the CRT screen (not shown), the operation of the specific key ends there.
After that, the selection data b is read out through step 222 or 223, and the transmission code table is changed. The selection data b at this time is (* 2) as shown in FIG.
Then, the table 2 of the transmission code table storage means 4 is selected, and the code for switching the TV to channel 2 and turning on the VTR is set as the transmission code A.
After that, when you operate the specific key, the code A is sent and the T
The V channel is set to 2 and the VTR is turned on, but at the same time, the table selection data storage means 3 selects the second table as the selection data a (* 2).
Is memorized. Therefore, after that, the transmission code table is not substantially changed, and every time the specific key is operated, the TV channel is set to 2 for the VT.
R is turned on.

If the character "STANDBY" is not displayed even after the transmission of the code B in step 224, the specific key is operated again, and it is determined that the count value n of the order counting means 7 has become 3. Ru
When (step 227), the transmission code C is transmitted (step 228), and the selection data c is stored in the table selection data storage means 3 (step 229). The transmission code C switches the TV to the video input, and the SW4 of the TV 82 shown in FIG. 5 is switched to the video input terminal VIN side. Video output terminals VOUT and T of VTR81
If the video input terminal VIN of V82 is connected by the cable 83, the signal from the specific signal source 816 of the VTR 81 is supplied to the video / audio output means 823 via the input terminal VIN and the switch SW4, and the character "STANDBY" is displayed. Is displayed. The selection data c at this time is for selecting the table 3 of the transmission code table storage means 4 by (* 3) as shown in FIG. 4, and the transmission code A is a code for switching the TV to the video input and turning on the VTR. Is set. In the subsequent operation of the specific key, the TV is set to the video input for the first time and the VTR is turned on. Further, since the data (* 3) for selecting the third table is stored as the selection data a in the table selection data storage means 3 by the transmission of the code A, the transmission code table is not changed thereafter.

If the character "STANDBY" is not displayed even when the code C is transmitted in step 224, it can be determined that the TV is not operating, and the specific key is operated again. When it is determined in step 227 that the count value n of the order counting means 7 has changed from 3 to another value, that is, 4, the transmission code D is transmitted (step 230), and the selection data d is further stored in the table selection data storage means 3. Is stored (step 231). The transmission code D is for switching the power supply of the TV, and in this case, the power supply is turned on. The selection data d is (* 1) as shown in FIG. 4, which selects the table 1 of the transmission code table storage means 4, and the transmission code is transmitted again from the beginning by the operation of the specific key thereafter. Become.

Incidentally, in the transmission code tables 2 and 3 shown in FIG. 4, if the transmission code having the first transmission order is transmitted,
As a general rule, the operation is completed by that, but the second to fourth codes are stored in consideration of the case where the TV cannot normally receive due to a key operation error or the like.

Further, the signal from the specific signal source 816 provided in the VTR 81 may be output from the time when the specific key is first operated to the time when the setting on the TV side is completed, and it is not shown in the drawing. The transmission of the code that controls to output a specific signal is started by the first operation of the key, and the transmission is stopped when another key is operated or when 30 seconds have elapsed from the operation of the specific key. Alternatively, a transmission code for controlling to output the specific signal for a predetermined period may be transmitted at the same time as the transmission of the code A-D.

If the broadcast signal is reliably received by the tuner 811 of the VTR 81, it is not necessary to intentionally provide a specific signal source.

According to the embodiment of the present invention as described above, when the specific key is operated within the predetermined time, for example, 30 seconds, the transmission codes are transmitted in the order stored in the transmission code table storage means 4. can do. In addition, when the key is operated at intervals of 30 seconds or more,
Alternatively, when another key is operated, the last transmission code transmitted last time can be transmitted by the operation of a specific key thereafter, and the transmission code is placed in the first rank. Since it is possible to automatically specify and transmit the transmission code in that order, after that, basically, the operation of the TV is set to match the operation state of the VTR and the connection state with the VTR with one key operation. It is possible to

By the way, although a plurality of code tables for determining the order of the transmission codes are provided in the above-mentioned embodiment, another embodiment of the remote control device in the case of using one code table will be described below.

For example, the transmission code creating means 2 stores the transmission codes in advance in a predetermined order so that the code transmitted by the last operation of the specific key is transmitted first. You may make it interrupt in the 1st of one code table.

Further, the transmission codes transmitted by the last operation of the specific key are accumulated for each code, and the transmission code creating means 2 is used to set the code table in order from the transmission code with the highest frequency. You may allow it.

Further, in the above embodiment, the table selection data stored in the table selection data storage means 3 was operated to automatically select the transmission code table in the transmission code table storage means 4. Even if a storage key and other keys are provided and operated so that the table selection data can be set as selection data desired by the user and can be stored in the table selection data storage means 3, Of course, it is possible to obtain the same effect as the example.

In the embodiment according to the present invention, the order of data in each table in the transmission code table storage means 4 has been described as a predetermined one. However, a data input key and a storage key are provided and the user desires. The code table may be freely configured in the order of transmission codes to be executed.

Further, according to the present invention, it is needless to say that the effect can be obtained with respect to all the electronic equipments provided with the remote control device, and the same effect can be obtained even when the carrier wave which is not the infrared ray is used. be able to.

The desired transmission code can be transmitted first by a simple operation without performing any operation, and then the transmission code can be sequentially transmitted from this transmission code.

As a result, the operability of the user's remote control device can be improved.
