Description

Description: TECHNICAL FIELD OF THE INVENTION The present invention relates to a remote control device using electromagnetic waves, ultrasonic waves, light, electric signals, etc., and relates to a remote control device for operating a plurality of devices by one remote control section. Is.

[Background Art of the Invention]

Conventionally, as this type of apparatus, there has been one in which the configuration shown in FIG. 1 and the processing shown in FIG. 3 are combined.

In FIG. 1, 1 is a remote operation unit, 2 is an operated device controlled by the remote operation unit 1, 3 is a receiver included in the operated device 2, and 4 is a processing device. Also, 6a and 6b are
The operated device is connected to the control signal line 5 from the operated device 2.

In the configuration of FIG. 1, the command (control command) sent by the remote control unit 1 is received by the receiver 3,
The signal is sent to the signal line 5 by the signal processing device 4. The command signal transmitted from the signal line 5 causes the operated device 6a,
6b …… performs the specified operation.

At this time, the signal processing device 4 processes the received signal as a re-send command as shown in FIG. 3 (3a), sends one command (3b), and ends the process (3c).

That is, a process of sending one operation or one command (sending one command or a plurality of commands) is performed.

[Problems to be Solved by the Invention]

Since the conventional remote control device is configured as described above, it is necessary to consider whether or not that device is selected among the operated devices 2 and 6.

That is, it is necessary to consider which operated device is in the power-on state or which operated device 6a, 6b ... Is selected by the function switch provided in the operated device 2. If these are not taken into consideration, it is necessary to sacrifice the function of one of the operated devices, which complicates the operation, and there is a drawback that the function cannot be utilized.

[Object of the Invention]

The present invention has been made to eliminate the above-mentioned conventional drawbacks, and an object of the present invention is to provide a remote control device which is easy to use and has the functions fully utilized.

[Means for Solving the Problems]

The remote control device of the present invention is connected to a remote control section for transmitting a remote control signal, a receiving section for receiving the signal, a signal processing for processing a signal received by the receiving section, and a signal processing section. In a remote operation device comprising a plurality of operated devices having a common control operation, wherein the signal processing unit is configured to send a remote operation signal to the plurality of operated devices, wherein the signal processing unit is When one of the plurality of operated devices is in the operating state and the other operated device is in the non-operating state, a remote control operation common to the plurality of operated devices in the operating state and the non-operating state. When the operation signal is sent from the remote operation unit, one operated device in the operating state performs the common control operation instead of the operated device in the non-operating state. Characterized by being adapted to deliver it to convert to a different remote control signal from the remote control signal from the remote control unit.

[Action]

When one of the plurality of operated devices is in the operating state and the other operated device is in the non-operating state, the signal processing section is provided for the plurality of operated devices in the operating state and the non-operating state. When a remote operation signal related to a common control operation is sent from the remote operation unit, one operated device in an operating state performs a common control operation instead of the operated device in a non-operating state. , The remote control signal from the remote control section is converted into a remote control signal which is transmitted.

Example of Invention

An embodiment of the present invention will be described below. The configuration is similar to that of FIG. 1, in which the processing of the signal processing device 4 operates as shown in FIG.

That is, the command transmitted by the remote control unit 1 is received by the receiver 3 and decoded by the signal processing device 4.

Here, as shown in FIG. 2, the operated device 2 processes the received signal as a re-send command (2a), the signal processing device 4 judges the state of the operated device 2 (2b), and depending on the state. Among a plurality of processes such as X command transmission, operation control of the operated device 2 (2c) or Y command transmission (2d),
After executing either, the process is terminated (2e).

Here, the state determination process of step 2b is a process of determining which one of the operated devices 2, 6a, 6b ... Is selected in advance. Which of the operated devices 6a and 6b can be controlled by turning on / off the power of the operating device and the function switch provided in the operated device 2
.. is selected depending on whether or not is selected.

Further, the X command and the Y command are commands of signals different from the signal transmitted from the remote control unit 1.

Next, specific examples according to the present invention will be described.

In the case of a remotely controllable television and a remotely controllable stereo system, the remote operation unit 1 is an operation unit of the stereo system. The operated device 2 is a remote control tuner (or amplifier), and the operated devices 6a and 6b are an amplifier and a television, respectively. Further, although not shown, a speaker is connected to the amplifier 6a.

In the above system, the sound of the television 6b can also be output from the stereo system (speaker connected to the amplifier 6a) and the television 6b itself.

When the command for increasing the volume of the stereo system is output from the remote control unit 1, the command is received by the receiving unit 3 provided inside the remote control tuner 2. When the power of the stereo system (amplifier, remote control tuner) is on, the signal processing device 4 outputs a command for increasing the amplifier volume so that the volume of the stereo system itself is increased, and the signal is transmitted through the signal line 5. It is input to the amplifier 6.

On the other hand, when the power of the stereo system is off, the signal processing device 4 converts the command for increasing the volume of the stereo system into a command for sending a command for increasing the volume of the television 6b, and outputs the signal to the signal line 5 to output the volume of the television 6b. Will increase.

Next, a case of another form will be described.

For example, the remote control unit 1 is a remote controller for a stereo system, the operated device 2 is an amplifier, the operated device.
6a is a CD player, and the operated device 6b is a cassette tape deck.

When a play command is output by the remote controller 1, it is received by the receiver 3 provided inside the amplifier 2. When the function switch of the amplifier 2 is in the CD position, the signal processor 4 causes the CD player to start playing.
The play command of the CD player is output, and the signal line 5
Is transmitted to and input to the CD player 6a to start playing.

On the other hand, when the function switch of the amplifier 2 is set to the tape position, the signal processing device 4 sends it as a play command of the cassette tape deck, outputs it to the signal line 5, and the cassette tape deck 6b starts playing. .

As described above, when there are a plurality of operated devices having the same function, the user can operate the device without considering which function is operated, or when the power is on or in the off state. it can.

〔The invention's effect〕

As is apparent from the above description, according to the present invention, one remote operation unit is used for one operated device which is in an operating state among a plurality of operated devices having a common control operation. A person can operate a common control operation without considering it.
