Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a learning remote control unit (hereinafter referred to as a learning remote control), and particularly relates to a configuration for registering correspondence information between a signal sending key and a remote control signal. .

[Prior Art] Learning remote controllers in which a user can assign arbitrary remote control signals to each signal sending key on the remote controller have come into widespread use.

This learning remote control is applicable to at most 1 electronic device.
It was designed to be controlled with a remote control, and therefore has a large number of signal sending keys. With such a large number of signal sending keys, it is difficult for the user to reliably remember which remote control signal is assigned to which signal sending key.

Therefore, alphabet keys are provided, and at the time of registration, key assignment information indicating which command or which electronic device the assigned signal sending key is for is entered.
It has been proposed to display key assignment information on a liquid crystal display for user confirmation if necessary.

[Problems to be Solved by the Invention] However, inputting key assignment information using alphabet keys is a complicated operation, and furthermore,
In the case of a learning remote control, many signal sending keys are provided, so it is very difficult to input key assignment information for all the signal sending keys. Furthermore, providing a large number of alphabet keys that are not used to send out the original remote control signal reduces the installation area of the original signal sending keys, which may reduce the advantages of the learning remote control.

The present invention has been made in consideration of the above points, and it is an object of the present invention to provide a learning remote control unit that allows a user to register key assignment information for a signal sending key to which a remote control signal is assigned by a simple operation. That is.

[Means for Solving the Problem] In order to solve the problem, in the present invention, a learning remote control unit that assigns a remote control signal given from an external remote control unit to a signal sending key captures an audio signal. a voice capturing means that recognizes the captured voice signal,
voice recognition means for outputting key assignment information regarding the remote control signal assigned to the signal transmission key; key assignment information storage means for storing the key assignment information output from the voice recognition means in association with the signal transmission key; The apparatus further includes key assignment information display means for extracting and displaying the key assignment information from the key assignment information storage means when confirmation of the key assignment details is instructed.

[Operation] The voice capturing means captures the voice signal and provides it to the voice recognition means, and the voice recognition means recognizes the captured voice signal and obtains key assignment information regarding the remote control signal assigned to the signal sending key. . The key assignment information obtained in this way is given to the key assignment/storage means and stored in association with the signal transmission key.

When the key assignment information display means is instructed to confirm the contents of the key assignment, the key assignment information display means retrieves the key assignment information from the key assignment information storage means and displays it for the user's confirmation.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

In FIG. 1, a learning remote controller 1 basically includes a control circuit 2 configured with a microcomputer that controls registration and transmission of remote control signals, and a remote control signal (not shown) given from a learning source remote controller (not shown). a light receiving section 3 which photoelectrically converts the optical signal) and provides it to the control circuit 2;
, a key switch circuit 4 equipped with a mode key for instructing various modes such as a registration mode, and a signal transmission key for signal transmission, a data memory 5 for storing a remote control signal designated for registration, and a key switch circuit 4 for storing a remote control signal for which registration is instructed; control port f
Il! 2 is comprised of a light emitting unit 6 that converts a remote control signal read from a data memory 5 into an optical signal and sends it to a target electronic device.

In addition to the above configuration, this embodiment has a configuration for registering key assignment information for remote control signals assigned to signal sending keys and having the user confirm the key assignment information as necessary. It is provided.

In other words, the audio signal (key assignment information) pronounced by the user
a microphone 10 that captures and converts it into an electrical signal;
Audio signals (electrical signals) such as the names of various electronic devices (for example, television receivers, video tape recorders) and operation command names targeted by the learning remote control 1 are stored in advance, and matching with the stored audio signals is performed. The voice recognition decoder circuit r#111 recognizes the voice signal given from the microphone 10 and outputs key assignment information consisting of code information, and converts the key assignment information code into a code that can be processed by the control diagram 12. A code conversion circuit 12 is provided which converts the signal and outputs it to the control circuit 2. As will be described later, such key assignment information is included at the time of registration and stored in the data memory 5 in association with the signal transmission key.

Note that since the voice recognition decoder circuit 11 is intended for several fixed types of electronic device names and fixed operation command names, its own configuration is not particularly complicated.

Further, a liquid crystal display section 13 for displaying key assignment information as necessary, and a liquid crystal driver circuit 14 for driving the liquid crystal display section 13 under the control of the control circuit 2 are provided.

The key switch unit 4 described above is provided with at least a registration mode key 4a and a key assignment information read mode key 4b.

Next, we will explain the process when the user registers any remote control signal to any signal sending key.
This will be explained using FIG.

First, the user presses the registration mode key 4a to instruct the learning remote controller 1 to select the registration mode (step 5P1). Thereafter, key assignment information (for example, television receiver, contrast) of the electronic device name and operation mode name to be assigned to the signal transmission key is sequentially input by voice (step S
P2>. At this time, the key assignment information is transferred from the voice recognition decoder circuit 11 to the control circuit 2 via the code conversion circuit 12.
given to. After that, the user presses one of the signal transmission keys to specify the signal transmission key to be registered, and points the light emitting part of the learning remote control (not shown) toward the light receiving part 3 of the learning remote control to select the learning remote control. A control signal is sent out (step SP3.4).

At this time, the control circuit 2 stores the remote control signal and its key assignment information in the area of the data memory 5 corresponding to the pressed signal transmission key, and also drives the liquid crystal driver circuit 14 after editing the signal. Liquid crystal display section 13
Then, the signal sending key information and key assignment information are displayed for a predetermined period of time as shown in the blocks of the liquid crystal display section 13 in FIG. 1, and the registration process is completed (step 5P5).

Next, a case in which a remote control signal is output without checking the assignment contents of the signal sending keys will be explained without using diagrams.

When the user knows the signal sending key for the command, etc. that he or she wants to instruct, he or she points the light emitting part 6 of the learning remote control 1 toward the light receiving part of the electronic device (not shown) to be controlled, and then Press the specified signal sending key. At this time, the control circuit 2 extracts a remote control signal from the area of the data memory 5 corresponding to the signal sending key based on the key information given from the key switch section 4, and supplies it to the light emitting section 6 to cause it to emit light. Depending on the control content, such an operation may be performed at least twice: when specifying the operation content (sound 1, contrast, etc.) and when specifying the change content of the operation content (volume level, contrast ratio). Ru. Further, for example, when instructing the playback mode of a video tape recorder, this is done only once.

Thus, a remote control signal is given to the controlled electronic device, and the controlled electronic device takes in the operation content and changes the operation content.

Next, the case where a remote control signal is output after confirming the assignment contents of the signal sending keys will be explained with reference to FIG.

In this case, the user first presses the key assignment information read mode key 4b (step 5 PIO). At this time, the control circuit 2 extracts the key assignment information from one area of the data memory 5 in a predetermined order, processes it together with the signal sending key information corresponding to the area address, and processes it into the liquid crystal driver circuit #114. is driven to display the contents on the liquid crystal display section 13 (step 5P11).

The user looks at the displayed content and presses the displayed signal sending key if it is the desired command, and does not perform any operation if it is not the desired command. The control circuit 2 monitors the press of the signal sending key, and when it detects the press, extracts a remote control signal from the area at that time and gives it to the light emitting unit 6 to send out the remote control signal (Step 5P12.13). .

On the other hand, if the button is not pressed, it is determined whether the display operation for all areas has been completed, and if it has not been completed, the above-mentioned steps are performed in order to display the q-allocation information, etc. regarding the next area. Returning to SpH, when the display of key assignment information and the like regarding all areas is completed, the series of processing is terminated (step 5P14).

Therefore, according to the above-described embodiment, when registering a remote control signal to a signal sending key in order to confirm the content assigned to the signal sending key, the key assignment information for the signal sending key is input by voice. This makes the input operation for such information much easier than in the past.

Note that in the above embodiment, when checking the key assignment information assigned to a signal transmission key, the key assignment information of one signal transmission key is sequentially displayed. Key assignment information regarding the sending key may also be displayed at the same time. In this case, if the plurality of displayed signal sending keys are related to the same electronic device, the usability for the user will be further improved. Further, a mode may be provided in which only one signal sending key is checked.

Further, in the above-described embodiments, the electronic device name and the operation command name are input by voice, but it is sufficient if at least the operation command name is input.

[Effects of the Invention] As described above, according to the present invention, key assignment information for confirming a remote control signal assigned to a signal sending key is input by voice and is registered in association with the signal sending key. Therefore, it is possible to obtain a learning remote control in which the key assignment information input operation is very easy.
