DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller capable of controlling operations of a plurality of devices, for example.

[0002]

2. Description of the Related Art In recent years, video tape recorders (hereinafter referred to as VT) have been developed.
R (abbreviated as Video Tape Recorder), monitor device (including television receiver), compact disc (C
D) can be remotely controlled using a remote controller in various devices such as a CD player. Further, when a so-called AV system is configured by the various devices as described above, since it is troublesome for a user to use a dedicated remote commander for each device, a large number of these devices can be operated by one remote controller. Known remote control systems are known.

In a remote controller used in such a remote control system, for example, when power on / off operation of a plurality of devices is performed, specifically, power on / off of a television receiver and a VTR is performed.
In the case where the power is turned off, a power key for turning on / off a power supply corresponding to both the television receiver and the VTR is provided to the remote controller. By performing the operation, the power of each device is turned on / off. Alternatively, one power key is configured to be shared by the television receiver and the VTR, and a select key for selecting operation on the television receiver side and operation on the VTR side is provided. After selecting either the TV receiver side or VTR side,
By operating the power key, the TV receiver or VT
R power on / off operation can be performed.

[0004]

By the way, as a use form of the above-mentioned AV system, when the television receiver and the VTR are used by reproducing the VTR from a state where the power is off, only the VTR is used. In addition, the television receiver for displaying the video signal of the VTR also needs to be turned on. Furthermore, VTR
When the audio output of the audio amplifier is connected to an audio device such as an audio amplifier, the device such as the audio amplifier also performs an operation of turning on the power. Further, even after the power of the television receiver and the VTR is turned on, it is necessary to perform an input switching operation for displaying the video of the VTR on the television receiver. Therefore, even if it is possible to operate a plurality of devices with one remote controller, in the case where a plurality of devices are used at the same time as described above, various operations such as turning on / off a power supply and other necessary devices are performed. The switching operation and the like must be performed one by one, which is very troublesome.

With respect to the operation for turning on / off the power, for example, when a predetermined key operation is performed, a command signal for turning on / off the power of the television receiver and the VTR is continuous. It is also conceivable to output it. However, usually, such power-on /
As a command signal for turning off, a so-called toggle signal, a command signal having the same code for both on and off, is used. Then, every time the toggle signal is received on the device side, the power is turned off if the device is currently turned on, and the power is turned on if the device is currently turned off. I have.

For this reason, if the television receiver and the V
If the user operates the power key to turn off both devices at the same time from the state where both TRs are turned on, the command signal is sent to one device due to the incorrect orientation of the remote controller. Is not supposed to be received. As a result, it is conceivable that one device is turned off while the other device remains on. However, in this case, since the power on / off command is a toggle signal, the power on / off states do not match each other no matter how many times the power key is operated. It is highly likely that both will be in an inconvenient state such that they cannot be turned off or on.

Therefore, as is conventionally known, if devices are connected to each other by a data bus line or the like to supply operation control signals, each device can be operated in conjunction with one key operation. Is possible, but in this case, the wiring becomes troublesome and complicated, and
Only devices that can be systematized according to the same standard in advance can be operated, and versatility is poor.

The control unit 1 is composed of, for example, a chip component, and is connected to a power supply E formed of, for example, a single battery as shown in the figure, and a DC voltage of the power supply E is supplied as an operation power supply. ing. The voltage of the power supply E is, for example, about 3V.

Further, the light emitting unit 5 is intended to emission output a command signal via infrared e.g., resistor R to the anode side of the light emitting diode D _L in the light-emitting portion 5
The DC power supply voltage of the power supply E is supplied via ₂ and the cathode is connected to the collector of the transistor Q. Together with the base of the transistor Q is connected to the control unit 1 side through the resistor R _1, the emitter is grounded to earth ground.
In this case, from the control unit 1 serves as a base current in response to the command signal is supplied to the base of the transistor Q via the resistor R _1, the transistor Q in response to the base current collector - between the emitter The conduction is controlled. Then, the light emitting diode D _L emits light by the collector current, so that a command signal by infrared rays is transmitted and output from the light emitting unit 5.

The remote controller R according to the present embodiment
Has a key operation unit 6 provided with keys for various operations.
Is provided. Here, FIG. 2 is an enlarged view of a portion of the key operation section 6 where various power keys for powering on / off various devices are provided. In the present embodiment, for example, the AV system shown in FIG. Power key 21 for simultaneously turning on / off the power of all the devices constituting the apparatus, mainly the television receiver 14
TV / power key 22 for turning on / off the power of the VTR, mainly for turning on / off the power of the VTR 12.
A power key 23 and an audio power key 24 for turning on / off the power of audio equipment such as the CD player 13 and the audio amplifier 11 are provided. The operation of the remote controller R when operating each of these power keys will be described later. FIG. 3 shows the key operation unit 6.
It is an enlarged view mainly showing a portion where keys related to the operation of the VTR 12 are provided. As shown in the figure, a reproduction key 31, a pause key 32, a stop key 33, a recording key 34, a rewind key for performing reproduction. A key 35, a fast forward key 36 and the like are provided. The layout patterns and shapes of the keys shown in FIGS. 2 and 3 are merely examples, and can be changed according to various conditions. The display unit 7 is formed of, for example, a liquid crystal display, and is provided on a panel surface of the remote controller R, and a predetermined display is performed by display control of the control unit 1.

Furthermore, the manufacturer setting switch SW ₁ shown in Figure 1 is provided to enable operations on manufacturer and model, such as the format of the command code is different. For example, as shown in the figure, an electronic switch terminal corresponding to each device manufacturer prepared in advance from Company A and Company B to Company n is provided, and even if the same manufacturer, a command code format for each model is provided. Are different, switch terminals are provided corresponding to each model.

For example, the maker setting switch SW ₁ is set to V
In this embodiment, if it corresponds to the TR, the ROM 3
_First , the format data of the maker / model command corresponding to each switch terminal of the maker setting switch SW1 is stored in advance. Then, if actually selected a manufacturer or user maker set switch SW ₁ corresponding to the model of VTR12 shown in FIG. 11, since, when transmitting a command signal against VTR12 is selected by the manufacturer setting switch SW ₁ The control unit 1 operates so as to output a command signal in the format of the specified manufacturer / model.

[0022] Thus, although not shown for convenience only one manufacturer setting switch SW ₁ in this figure, by providing the same manufacturer setting switch for other VTR12 other devices, for all devices of the AV system Even when the manufacturers are different, the operation can be performed by the remote controller R. Note that the manufacturer setting switch SW ₁ by the hardware configuration shown in FIG, for example may be provided, such as DIP switches, are also possible by software configuration, for example, the predetermined at the key operation unit 6 Based on the simultaneous operation of a plurality of keys, the CPU 2 sets the data of the selected maker / model in the RAM 4, or displays a setting menu on the display unit 7 or the like and selects the maker / model from the menu screen. May be performed.

The automatic input changeover switch SW ₂ shown in FIG. 1 is operated by a key operation for reproducing the VTR 12 in a manner to be described later. When a switching command for switching the television receiver to a displayable state is transmitted, a switching command to be transmitted to the television receiver 14 is to be selected in accordance with a connection mode described below. You.

For example, in the AV system shown in FIG.
A plurality of connection modes for supplying the output of the VTR 12 to the television receiver 14 are conceivable.
In addition to the configuration in which the video output terminal of the VTR is connected to the video input terminal corresponding to the composite signal or the S video signal on the television receiver 14 side, the reproduction RF signal output on the video side is connected to the television receiver. A configuration for connecting to the antenna input on the 14 side is conceivable.
Therefore, in this embodiment, according to the actual connection between the playback output of the VTR 12 and the video input of the television receiver 14,
Advance automatic input switch SW ₂ that the user previously selected set, if the operation for VTR playback is made, will be switched to the input corresponding to the reproduction output of VTR12 simultaneously.

Specifically, in a mode in which the VTR output is connected to the television receiver 14 by an RF signal, the reproduced image is usually displayed on one or two channels of the television receiver 14, for example. (Note that the settings for channel 1 and channel 2 are set on the VTR 12 side according to the convenience of the broadcast channel for each area, for example).
Automatic input switch SW ₂ users in advance in such a case, it suffices to keep switching the 1CH terminal or 2CH terminal. Alternatively, if you connect the video output of VTR12 to the video input terminal of the television receiver 14 side, for example in response to a video input terminal that is actually connected, Video1 terminal automatic input switch SW ₂ or, You can switch to one of the Video2 terminals. In addition, in a use environment in which it is not necessary to perform automatic switching, a switch terminal corresponding to automatic switching off may be selected. Since the total number of video input terminals installed on the television receiver 14 is not always _two , the above-mentioned Vide
o The number of terminals may be changed. Although also automatic input switch SW ₂ is shown as a hardware configuration, in the same way as described in the manufacturer setting switch SW _1, it may be configured to be set by software configuration.

In the remote controller R of the present embodiment configured as described above, for example, FIG.
The command signal for controlling the power on / off of each device of the AV system shown in FIG. 1 is not based on the toggle code as described above, but is a command signal dedicated to power on (hereinafter abbreviated as an on command) and a power off. A dedicated command signal (hereinafter abbreviated as “off command”) is stored in ROM beforehand.
3 is set. For example, when a key operation for powering a required device is performed by the remote controller R, an ON command and an OFF command corresponding to the required device are output alternately for each key operation in principle. To be. Further, in this embodiment, every time the various power keys described with reference to FIG. 2 are operated, an operation of continuously outputting an ON command corresponding to a plurality of required devices and an operation of sequentially outputting an OFF command are sequentially performed. Are performed alternately. This makes it possible to turn on / off the power by synchronizing the required devices with a single key operation. Less than,
The respective operations of the remote controller R of the present embodiment as described above will be described with reference to the flowcharts of FIG. 4 to FIG.

First, the remote controller R of this embodiment
The case where the system power key 21 (see FIG. 2) is operated in the above will be described with reference to the flowchart of FIG. The system power key 21 is used, for example, when the user wants to simultaneously turn on / off all the power supplies of the AV system as shown in FIG. For example, in this routine, when the system power key 21 of the key operation unit 6 is operated, the CPU 2 determines this in step F101, and proceeds to step F102 to operate the system power key 21 last time. It is determined whether the series of command signals output at this time is from the processing system of steps F103 to F106 to be described below or from the processing system of steps F107 to F110. It is assumed that the CPU 2 sequentially stores the data in the RAM 4 as to which processing system the series of command signals output when the previous operation of the system power key 21 was performed. You. In step F102, when it is determined from the stored contents of the RAM 4 that the processing of steps F107 to F110 was performed at the previous operation of the system power key 21, the entire AV system shown in FIG. 11 is turned on. Processing is performed. That is, as shown in steps F103 to F106, for example, an ON command for the television receiver 14 is output, then an ON command for the audio amplifier 11 is output, and then the VTR 12 and the CD player 13 are sequentially output. The processing is performed so as to output the ON command of That is, a signal corresponding to each of the above ON commands is sequentially supplied from the control unit 1 to the base of the transistor Q of the light emitting unit 5.

On the other hand, if it is determined in step F102 that the processing in steps F103 to F106 has been performed at the time of the previous operation of the system power key 21, if the television receiver 14, the audio amplifier 11, the VTR 12, and the CD player 13 Processing for outputting an off command is sequentially performed for each of them (the processing of steps F107 to F110).

In the following description, a case in which an ON command is output continuously to turn on the power of a plurality of required devices will be referred to as an “ON command system”. The case where the off command is continuously output so as to turn off the power of the plurality of devices is also referred to as an “off command system”. For example, in the case of FIG. 4 described above, steps F103 to F106 are "ON command type".
Is output, and steps F107 to F110 are processing for the "off command system".

Through the above processing, each time the system power key 21 is operated, the above-mentioned devices (the television receiver 14, the audio amplifier 11, the VTR 12, the CD player 13) alternately repeatedly turn on / off the power. Can be operated as follows. That is, A is operated by one key operation on the remote controller R of the present embodiment.
It is possible to control on / off of the entire V system. Further, even if the command signal is output from the remote controller R, even if a certain device cannot receive the command signal for some reason and the power on / off states of the respective devices of the AV system become inconsistent, In this embodiment, as described above, the command signal by the toggle code is not used, and the ON command and the OFF command are used individually.
It is possible to match the power on / off state of each device soon. For example, when the television receiver 14, the audio amplifier 11, the VTR 12, and the CD player 13 are all powered on and the system power key 21 is operated to simultaneously turn off the power of these devices (off) Command-related operation), the television receiver 14 cannot receive the off command and the other audio amplifier 11, VTR 12, C
It is assumed that the D player 13 has been turned off, but the television receiver 14 remains on. In this case, if the system power key 21 is operated again by pointing the remote controller R in an appropriate direction, all the above-mentioned devices are once in a power-on state by the output of the ON command of each device at this time. Will be. Thereafter, by operating the system power key 21 again, all the devices can be simultaneously turned off at this stage as desired by the user.

Even if the maker differs among the devices constituting the AV system, as described with reference to FIG. 1, a maker setting switch is selected in advance for each type of device, and the device of each maker is selected. Is enabled, an ON command and an OFF command corresponding to the manufacturer of each device are output, and the processing operations of steps F103 to F106 and F107 to F110 shown in FIG. 4 are executed. become.

Next, referring to the flowchart of FIG.
The operation of the remote controller R when the TV / power key 22 (see FIG. 2) is operated on the key operation unit 6 will be described. In the AV system shown in FIG. 11, the audio signal output from the television receiver 14 is output from the audio amplifier 1 so that the sound from the television receiver 14 can be reproduced and output by the speakers 15 and 15 as described above.
Therefore, at the time of using the television receiver 14, at least the television receiver 1 is used.
When the television receiver 14 is not used when the power supply of the audio receiver 11 and the audio amplifier 11 is turned on, the power supply of the audio amplifier 11 is also turned off together with the television receiver 14. Originally TV / Power key 22
Is provided to perform on / off control of the power of the television receiver 14. In consideration of the above-mentioned usage, in this embodiment, the television / power key 22 is operated when the television / power key 22 is operated. The power on / off control of the audio amplifier 11 as well as the receiver 14 is set so as to be able to be performed in synchronization.

For example, in the present embodiment, step F201 in FIG.
When it is determined that the operation has been performed in a state of waiting for the operation of the TV / power key 22 as shown in FIG.
The CPU 2 proceeds to step F202 to determine whether the command was output from the on-command system or the off-command system at the time of the previous operation of the TV / power key 22 by, for example, RA
The determination is performed with reference to the data content of M4.

If it is determined in step F202 that an off-command system was output during the previous operation of the TV / power key 22, the CPU 2 outputs an on-command for the television receiver 14 by the CPU 2. (F203), and then the audio amplifier 11
An on-command-type process for outputting an on-command is performed (F204), and the process returns to the original routine.
On the other hand, in step F202, the previous TV / power key 2
If it is determined that the on-command system has been output at the time of the operation of 2, the off-command system for outputting the off command for the television receiver 14 and then outputting the off command for the audio amplifier 11 The processing is executed (steps F205 → F206).

By performing such processing, TV /
Each time the power key 22 is operated, the television receiver 1
The power-on and power-off operations are alternately repeated so that the audio amplifier 4 and the audio amplifier 11 work together. As a result, the power control of both devices can be performed simultaneously by operating only the TV / power key 22.

Next, the operation of the remote controller R when the VTR / power key 23 is operated will be described. For example, if the user decides to switch on the power supply of the VTR 12 and use it in the case of the AV system shown in FIG. 11, in addition to the television receiver 14 on which the video output is displayed, an audio signal of the VTR is input. A usage form in which the audio amplifier 11 is also turned on and used together can be considered. Therefore, in this case, the VTR
Every time the power key 23 is operated, the remote controller R operates so that on-command and off-command operations for the VTR 12, the television receiver 14, and the audio amplifier 11 are alternately performed.
The TR 12, the television receiver 14, and the audio amplifier 11 are synchronized so that the power on / off operation state is repeated at once.

As a process of the control unit 1 of the remote controller R for realizing such an operation, as shown in the flowchart of FIG.
From the state of waiting for the operation of the TR / power key 23,
If it is determined that the operation has been performed, the CPU 2 proceeds to step F302. In this step, at the time of the previous operation of the VTR / power key 23, it is determined whether a command output of an on-command type or an off-command type has been performed, and it is determined that the previous time was an off-command type. For example, for example, the CPU 2 sequentially performs a process for outputting an ON command for the television receiver 14, the VTR 12, and the audio amplifier 11 (steps F303 → F304 → F305). If it is determined in step F302 that the on-command system has been output last time, the television receiver 14, the VTR 12,
Processing for outputting each off command signal for the audio amplifier 11 is sequentially executed (steps F306 → F3).
07 → F308).

Next, the case where the audio power key 24 is operated will be described. The audio power key 24 is a key capable of controlling the power on / off of a plurality of devices required when listening to music or the like with an audio device. For example, in the case of an AV system as shown in FIG. CD player 13 as a sound reproducing device
The power on / off control of the audio amplifier 11 for amplifying and outputting the reproduced audio signal of the CD player 13 is performed in synchronization.

As a processing operation when operating the audio power key 24, as shown in the flowchart of FIG. 7, if it is determined in step F401 that the audio power key 24 has been operated, the previous audio・
The command output at the time of operating the power key 24 is determined. If it is determined that the output of the off-command type has been previously output, the audio amplifier 11 is followed by the CD.
A process of outputting an ON command for the player 13 is performed (steps F403 → F404). If it is determined in step F302 that the on-command system has been output last time, an off-command signal for the audio amplifier 11 and the CD player 13 is sequentially output (steps F405 → F406).

By the above-described processing, the audio power key 2 is operated in the same manner as the operation of each power key described above.
4 each time the remote controller MR
As a result of the ON command and the OFF command being alternately output to the audio amplifier 11 and the CD player 13, the audio amplifier 11 and the CD player 13 can perform the power on / off switching operation in conjunction with each other.

As described above, in this embodiment, the system power key 21 and the TV are used as power on / off keys in accordance with various conceivable usage modes of the AV system.
・ Power key 22, VTR ・ Power key, audio ・
Various power keys such as a power key 24 are provided, and each time an operation is performed by each power key, on and off commands of a plurality of required devices are alternately output. Thus, when the user selects and operates the power key most corresponding to the usage mode of the AV system at that time, the user performs the power on / off operation of a plurality of target devices by one key operation each time. be able to. Further, in this embodiment, since the power-on / off command signal does not use the toggle code but uses the power-on-only ON command and the power-OFF-only OFF command, for example, the device to be operated for some reason Even if the power on / off of the power supply is out of synchronization, it is possible to almost certainly make the power on / off state coincide again by the subsequent key operation.

In the case where only required devices in the AV system are individually turned on / off individually, for example, various power keys for turning on / off only specific devices are provided, and the user can use these keys. It is conceivable to turn on / off only the desired device by operating a key.

Next, another embodiment of the present invention will be described. In this embodiment, the configurations of the remote controller R and the key operation unit may be the same as those shown in FIGS. 1, 2 and 3, and the AV system in this case is also shown in FIG. The following description is based on the configuration shown. For example, as one of the usage modes in the AV system shown in FIG. 11, after displaying the video reproduced by the VTR 12 on the television receiver 14, the VTR 12
May be terminated, and then the television receiver 14 displays a broadcast-wave video program. In this embodiment, corresponding to such a usage pattern, for example, as an outline, the VTR / power key 23 shown in FIG.
When the ON command for the VTR 12 is output by the operation described above, the ON commands for the VTR 12, the television receiver 14, and the audio amplifier 11 are sequentially output in the same manner as described with reference to FIG. However, when outputting an off command for turning off the power of the VTR 12, it is necessary to switch to a state in which broadcast waves are displayed on the television receiver 14 continuously. It is configured to output a simple command signal. Thus, in this embodiment, the VTR 12 is operated by operating the VTR / power key 23 of the remote controller R.
When the power supply of the VTR 12 is turned on, the television receiver 14 and the audio amplifier 11 are also switched on in synchronization with this. On the other hand, when the power supply of the VTR 12 is turned off, Automatically, the television receiver 14 is switched from the state for displaying the reproduced image of the VTR to the state for displaying the image by the broadcast program.

Accordingly, in the present embodiment, the operation of the “on command system” is the same as that of the above-described embodiment,
The on command is sequentially output to each of the TR 12, the television receiver 14, and the audio amplifier 11. The “off command system” includes outputting an off command to the VTR 12 and broadcasting to the television receiver 14. An operation of outputting a switching command for displaying a wave is performed.
Each time the power key 23 is operated, the above-mentioned "ON command type" and "OFF command type" operations are alternately performed.

It is assumed that the user turns on the power of the VTR 12 after turning off the power of the VTR 12 by operating the VTR / power key 23 or the like. Then, when the user operates the VTR / power key 23 to turn off the power of the VTR 12 by operating the remote controller R next time, the operation of the remote controller R is in the order of outputting the on-command system. Therefore, the VTR 12 is still powered on. In other words, the order of the power supply on the device side and the corresponding order of the on / off command of the remote controller R are shifted, and a good feeling of use cannot be obtained.

Therefore, the remote controller R of this embodiment is
Then, when the VTR / power key 23 is operated, the previous stage (here, the previous VTR / power key 23
During the period from the time when is operated to the time when the current VTR / power key 23 is operated).
A key for causing the R12 to execute a predetermined operation including, for example, reproduction, pause, recording, and the like (hereinafter, such keys are collectively referred to as a "VTR operation key").
However, only when it is actually operated,
At the stage before the operation of the power key 23, since the possibility that the VTR 12 is in the ON state is very high, the above-described operation of the off-command system is performed. As a result, even when the power-on operation is performed on the VTR 12 main body side as described above and the correspondence between the on-off relationship between the device side and the remote controller R is deviated, the reproduction / recording or other operations are normally performed by the remote controller. If it is performed by the operation of R,
Next, when the VTR / power key 23 is operated, the remote controller R performs an off-command operation, and
Since the power of the TR 12 is switched off, the possibility of the above-described inconvenience can be significantly reduced. The "VTR operation key" includes, for example, a play key 31, a pause key 32, a stop key 33, a recording key 34, a rewind key 35, a fast forward key 36, and the like as shown in FIG. Other various keys not shown here, for example, used for setting a reserved recording, setting various modes, and the like may naturally be the “VTR operation keys”.

FIG. 8 is a flowchart showing the processing operation of the control unit 1 for realizing the operation of the remote controller R of the present embodiment as described above. In this routine, first, the CPU 2 executes the VTR
The operation of the power key 23 is on standby, and if it is determined that the operation has been performed, the process proceeds to step F502, and the operation is previously selected at a stage before the operation of the VTR / power key 23 determined in the previous step F501. It is determined whether any one of the “VTR operation keys” is operated. For example, in the case of this embodiment, when a VTR operation key is operated, a required command signal is output based on the specific contents of the VTR operation key.
Data indicating that the operation of the TR operation key has been
It is assumed that a process of setting to M4 is performed. Therefore, the determination processing in step F502 can be executed by referring to the operation data of the VTR operation key in the RAM 4.

If it is determined in step F502 that the VTR operation key has not been operated, step F5
Proceeding to 03, if it is determined that the VTR operation key has been operated, the flow proceeds to step F507 and the "off command system"
Is performed. If the process proceeds to step F503, it is determined whether the operation of the on-command system or the off-command system was performed at the time of the previous operation of the VTR / power key 23, and the on-command system was output last time. If it is determined that the off-command type has been output, the process proceeds to step F507.
Proceeding to F504, processing for the "on command system" of this embodiment is sequentially performed. That is, VTR1
2. Television receiver 14, and audio amplifier 1
The process of outputting an ON command for 1 is performed in step F5.
Executed for each of 04, F505, and F506. Then, the process proceeds to step F510 to clear the VTR operation key data previously set in the RAM 4, and then returns to the original routine.

On the other hand, if it is determined in step F502 that the VTR operation key has been operated,
If it is determined that the operation of the on-command system was performed last time, the process for the "off-command system" of the present embodiment is executed, that is, the process proceeds to step F507, and the off-command for the VTR 12 is firstly performed. In the next step F508, a command signal for switching the input selection so that the broadcast program can be displayed on the television receiver 14 is output. As the reception channel to be switched at this time, for example, the channel of the broadcast wave selected before switching to the video input channel on the remote controller R side is set to R.
A method of storing data in the AM4 or the like and outputting a command signal for switching to this channel is conceivable.

By the processing of steps F507 → F508, the power supply of the VTR is turned off, and for example, the television receiver 14 changes from the state in which the channel or the input terminal is selected so that the video of the VTR can be displayed. ,
This automatically switches to a state in which a broadcast program is displayed.

Then, in the processing of the "off command system" of this embodiment, in step F509, a command for switching the antenna input from the video input side to the broadcast wave input side is output to the television receiver 14. To be. This process is provided, for example, when the output of the VTR 12 is modulated by an RF signal and connected to the antenna input of the television receiver 14. That is,
Assuming that the process of step F509 is omitted, by simply switching the channel of the television receiver 14 to the broadcast wave side by the process of step F508, the antenna remains in a short term until the VTR 12 is completely turned off. In the input unit, since the state where the VTR side is input continues, a noise screen may be displayed on the television receiver 14 during that time. Therefore, in the above-described step F509, the television receiver 14 transmits the antenna input from the VTR side to the broadcast wave (antenna 1).
6) If you immediately switch to the side, visually VTR
The image display by the broadcast wave is performed almost simultaneously with the operation of the power key 23, and the noise screen can be prevented from being displayed. After the processing in step F509 has elapsed, the flow proceeds to step F510 to clear the VTR operation key data, and then returns to the original routine.

The operation of the remote controller R has been described as being performed by operating the VTR / power key 23.
For example, a "VTR power / TV switching key" (not shown) is newly provided so as to correspond to the operation described with reference to FIG. 6 in the previous embodiment, and the "VTR power / TV switching key" is provided. The operation described in the present embodiment may be performed when is operated. In the embodiment shown in FIG. 6, the VT shown in FIG.
A process of determining whether or not the R operation key has been operated (step F502) may be added so that when the VTR operation key is operated, off-command processing in steps F306 to F308 is executed. Can be Further, although the VTR 12 is an operation target as a video reproducing device here, the present invention can be applied to other video reproducing devices such as a video CD player and a laser disk player.

In this embodiment, the VTR is operated in accordance with the operation of the remote controller R described with reference to FIG.
When the playback key 31 (see FIG. 3) is operated, the remote controller R outputs a VTR playback command signal for causing the VTR 12 to perform video playback and also outputs a VTR playback command signal to the television receiver 14. For example, VTR
It is configured to perform an operation of outputting a command signal for switching the 12 outputs to the connected video input.
In this case, the command output for switching the video input to the VTR side, the required command signals based on the setting of the automatic input changeover switch SW ₂ described in FIG. 1 is selected.

FIG. 9 is a flowchart showing the processing of the control section 1 for realizing the operation of the remote controller R. If it is determined in step F601 that the VTR playback key 31 has been operated, the CPU 2 proceeds to step S601. Proceeding to F602, first output a VTR playback command, then step
Proceeding to F603, the automatic input changeover switch S shown in FIG.
To determine the setting state of the W _2. Here, if the automatic input changeover switch SW ₂ of FIG. 1 is set to "1CH", and outputs a command signal to switch to one channel to the television receiver 14 (step F604),
Similarly, if "2CH" is set, a command signal for switching to two channels is output (step F6).
05) If "Video1" is set, a command signal for signal switching is output so that the video signal connected to the video input terminal 1 of the television receiver 14 is displayed (step F606). If "Video2" is set, a command signal for switching to the video of the video input terminal 2 is output (step F607), and the process returns to the original routine. Although not shown here, in the processing of each step F604 and step F605, V
Since this corresponds to the case where the reproduction output of the TR 12 and the television receiver 14 are connected by an RF signal, for example, the switching of the antenna input from the broadcast wave receiving antenna 16 to the RF output of the VTR 12 is performed. A command signal is also output.

When the VTR playback key 31 is operated by operating the remote controller R in this manner, the VT
In conjunction with the start of the reproduction operation by R12, the television receiver 14 is also automatically switched to a state in which the reproduction output of the VTR is displayed.

By the way, in each of the above-described embodiments, even when the makers of the respective devices constituting the AV system are different from each other, the maker setting switch shown in FIG. 4 can output a command signal in a format corresponding to the maker. In the processing operation shown in each of FIGS. To output a command signal.

For example, the processing operation of the controller 1 at the time of setting the maker is performed as shown in the flowchart of FIG. In this case, the case where the type of the device to be set is VTR is shown. For example, in this routine, first in step F701,
To determine the settings of the manufacturer setting switch SW _1, for example, when it is set to Company A, with respect to data RAM14 indicating that for example the command signal for the VTR12 is due Company A format Is set,
(Step F702), if Similarly manufacturer setting switch SW ₁ is set to the B company, data indicating the B company RAM4
Is set to (Step F703). Further, if it is set to a maker or a model of other n companies, step F704
As described above, data corresponding to the set maker and model is set in the RAM 4. When outputting a command signal to the VTR 12 in response to a predetermined key operation, for example, the CPU 2 determines the manufacturer and model data stored in the RAM 4, and further outputs a required command in a format corresponding to the data. ROM data
3 to execute a command signal output process. In this case, the manufacturer setting switch SW ₁
Although it is assumed that it is provided corresponding to the TR12, if it is configured so that the maker setting can be similarly performed for the other devices constituting the AV system as described above, the other devices are also provided with the above-described VTR12. As in the case of, the operation by the remote controller R can be performed for different manufacturers and models.

As described with reference to FIGS. 4 to 8 above, when either an on-command type or an off-command type is output as a command signal corresponding to the power key operation, a specific example will be described. Although not shown, the display unit 7 provided in the remote controller R displays, for example, whether the command signal output by the current power key operation is an on-command type or an off-command type. If the operation status related to the on / off command can be visually confirmed, the usability can be further improved.

Further, in each of the above embodiments, the remote controller R of the present invention has been described as corresponding to the AV system as shown in FIG. 11, but it is not limited to the AV system as shown in FIG. No. For example, even in the case of an AV system configured by combining more video / audio devices and the like, it is possible to configure so as to simultaneously control a plurality of required devices as in the present invention. The type of a plurality of devices to be operated for each power key can also be arbitrarily set. For example, the user can arbitrarily perform this setting by performing a predetermined key operation or the like. Further, the remote controller R of the present invention is not limited to the one corresponding to the AV system as described above, and is configured by combining a plurality of computer devices and mechanical devices in, for example, an office, a factory, and even a home. It can be applied to remote controllers for operating various systems. Further, the command signal output from the remote controller R is, for example, a signal that can output the same command indicating the model and its operation several times continuously as used in a conventional remote controller. Not even.

ing. As a result, the on / off operation of a plurality of required devices can be performed almost certainly in conjunction with a single key operation without performing a power operation for each device. Has the effect of simplifying and improving usability. Such an interlocking operation of the device of the present invention is realized by a command signal from a remote controller. In particular, since there is no need to connect the devices by a wire such as a bus line, troublesome wiring work is not required, and system devices are not required. The wiring between them can also be reduced.

Further, when a predetermined power key operation of the remote controller is performed, if a key operation for causing the device to execute a predetermined operation is performed before the power operation, an off command is output. Therefore, for example, even if the power of the device is turned on by a switch on the main body side and the correspondence between the power state of the device and the output order of the on / off command on the remote controller side is shifted, the power operation at this time causes the device to be turned on Since the power supply of the remote controller can be turned off, the usability of the remote controller is improved.

When a playback operation for playing back a predetermined video playback device such as a VTR is performed,
At least a playback command signal for playing back the video playback device, and a display switching command for switching the display so that the video of the video playback device is displayed on the display device to which the video output of the video playback device is connected. By sequentially outputting signals, the AV operation can be performed only by the playback operation of the video playback device.
As a result, the system is in a state where the reproduced video can be viewed, and similarly, there is an effect that the usability of the system is improved.

Further, since the present invention can be realized by a software configuration in the control unit of the remote controller, the cost is not particularly increased, and it is possible to cope with an existing system almost as it is.
