Abstract

PURPOSE:To execute a series of remote control operation only by depressing one function key by providing the function key to execute a general remote control operation. CONSTITUTION:When a function setting key is depressed and a series of the desired remote control operation key is successively inputted, a series of the code is successively written into the prescribed memory area of a memory means 106. Thereafter, when a function key 12 is depressed, a control means 104 reads a series of the code stored in the memory means 106 and transfers it to a transmitting means 108. Thus, a series of the code is sent from the transmitting means 108 to a TV main body. Consequently, for example, the remote control operation to execute the reproduction from the condition of a power source off to VTR can be executed only by depressing one function key.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a remote control transmitter that allows a series of remote control operations to be performed by simply pressing one function key.

(Prior art) Recent television receivers (TV) and video tape recorders (
VTR), video discs (VD), etc. are usually equipped with a remote control.

Such a remote control is like replacing the operation panel of the main body of the device with the keyboard of the remote control transmitter for remote control, and the key operation procedure is almost the same as that of the operation panel.

Therefore, for example, when selecting a television channel using a remote control, the user only needs to press the corresponding channel selection button on the remote control transmitter, and to make the VTR perform fast forwarding, the user only needs to press a send button. Then, from remote control transmission 2K, select that button (
A remote control operation signal corresponding to the key) is emitted, and the desired operation is executed by giving it to the TV or VTR by wireless or A-line.

(Problems to be Solved by the Invention) As mentioned above, using a remote control has the advantage of allowing you to select the desired operation at any time from the remote control transmitter at hand, so you do not have to go all the way to the device itself. However, the usability of key operations has not been improved much.
In particular, when operating a device such as a VTR that requires a complicated operation procedure with a remote control, a large number of key operations corresponding to the operation procedure must be performed at the same time.

For example, to make a VTR perform playback from a power-off state, the power button, TV/VTR selection button, channel selection button, and playback button on the remote control transmitter must be pressed in sequence.

This series of key operations is tedious even for experienced users.
Especially when you are in a hurry, you may make mistakes in your haste, and it is difficult for people who are weak in operating machines, such as the elderly, to handle it.

The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a remote control transmitter that allows a series of remote control operations to be performed simply by pressing one function key.

(Means for Solving the Problems) The configuration of the present invention for achieving the above object includes: a keyboard including a function key and a setting key assigned to the function key to set a series of remote control operations; a decoder that decodes key inputs and generates a corresponding code; a transmitter that modulates the code and outputs a remote control operation signal; stores a series of codes corresponding to a series of key inputs that instruct the series of remote control operations; In the function setting mode using the setting key, a series of codes from the decoder is written into the storage means, and when a key other than the function key is pressed in the normal mode, the code from the decoder corresponding to the key input is written in the memory means. Setting/transfer control means that transfers the code to the transmission means, and when a function key is pressed in the normal mode, reads a series of codes corresponding to the function from the storage means and sends them to the transmission means at predetermined time intervals; It is characterized by comprising the following.

(Function) The keyboard according to the present invention is provided with a function key and a function setting key in addition to ordinary keys such as a channel selection key, a recording key, and a playback key.

When performing one-by-one remote control operations, press the key that instructs the desired operation (For example, when you press the channel selection key, the channel indicated by that key is selected. In this case,
The code from the decoder that corresponds to that selection key is set/
The information is immediately transferred to the transmitting means through the transfer control means.

Then, when performing batch remote control operations according to the present invention, the function key is pressed. A predetermined series of remote control operations is assigned to this function key, and when this key is pressed, the setting/transfer control means reads out a code instructing the series of remote control operations from the code storage means and sends a certain number of remote control operations to the transmission means. Send at time intervals. Thus, the transmitting means intermittently transmits remote control operation signals in the same manner as when a series of keys are pressed one by one, and the device body executes a series of operations instructed by the remote control operation signals.

(Embodiment) An embodiment of the present invention will be described with reference to FIGS. 1 to 3.

FIG. 1 shows the basic configuration of a remote control transmitter according to this embodiment. The keyboard 100 has a normal circuit configuration, but includes special keys (function keys, function setting keys) as described later. Decoder 102
is of conventional construction and decodes each keystroke on keyboard 100 to generate a corresponding predetermined code. The setting/transfer control means 104 is composed of a microprocessor (CPU), and the code storage means 106 is a memo IJ (RAM) that can be written at any time.
). The transmitting means 108 has a wireless configuration and transmits the code received from the setting/transfer control means 104 at 40 KHz.
A remote control operation signal is created by modulating it with a nearby carrier and output from the infrared light emitting diode 110.

FIG. 2 shows the keyboard of the remote control transmitter according to this embodiment.

This remote control transmitter can selectively control a television receiver (TV) and a video tape recorder (VTR) with one unit, and the keyboard 100 has a TV key 46 for selecting the TV and a TV key 46 for selecting the VTR. VTR key 4 for
8 is provided.

Keys 20-42 are ordinary keys that serve two functions. For example, the key 20 functions as a selection key for instructing the first channel when TV is selected by the TV key 46, and as a key for instructing rewinding when a VTR is selected by the VTR key 48. It has become.

Keys 12 to 18 are function keys, and pressing each of these keys instructs a series of preset remote control operations. The key 44 is a function setting key, and when setting a function, first press this key, then press the keys instructing the desired series of remote control operations in sequence, and finally press any function key Fi. It looks like this.

For example, when setting a function for a series of remote control operations to search for and automatically play the previous recorded program from a power-off state, first press the function setting key 44 to enter the function setting mode, then press the power key 44. 45 → 2 channel selection key 22 → VTR key 48 → Counter display (CB) key 34 → Program search (PS) key 36 → Rewind key 20, press each of the above keys in this order, and finally press any function key, e.g. Just press function key 12. Once a series of remote control operations have been set in this manner, simply by pressing the function key 12, a remote control operation signal corresponding to the above series of key operations will be generated.

Reference numeral 50 is a window through which infrared remote control operation signals emitted from the inside pass through to the outside, and in the normal mode for remote control operation, point this window 50 at the TV or VTR body and press the corresponding key. However, since no remote control operation signal is emitted when setting the function, there is no need to direct the window 50 toward the TV or VTR body.

Next, the operation of the remote control transmitter will be explained with reference to the flowchart shown in FIG.

First, when some key input is made on the keyboard 100, a code corresponding to the key input is generated by the decoder 102 and given to the setting/transfer control means 104.

Based on the code, the control means 104 checks whether the pressed key is the function setting key 44 (step 2), and if so, enters the function setting mode.

In this mode, when there is a next key input, the corresponding code from the decoder 102 is written into a predetermined storage area of the code storage means 106 (step 3.4). for example,
In the case of the above setting example, power key 45 → 2 channel selection key 22 - VTR key 48 → power counter display (CB)
Since key inputs are made in the order of key 34 → program search (PS) key 36 → rewind key 20, codes corresponding to these key inputs are sequentially written into a predetermined storage area of code storage means 106. Then, when the function key 12 is finally pressed, the control means 104 identifies the code corresponding to the key input and performs processing to make the series of codes correspond to the function key (Fl) 12 (step 5).゜6). That is, an identification code (pointer) indicating that the series of codes written in the memory area corresponds to a function key (Fl) is written in a predetermined memory location, and at the same time the number N of the series of codes is determined.
Also write.

If it is determined in step 2 that it is not a function key, then check whether it is a function key (step 7), and if so, read out a series of codes corresponding to that function key from the code storage means. The data is transferred to the transmitting means 108 (Steps 9 and 10). At this time, code reading and transfer are performed sequentially in the same order as writing.

That is, in the above example, the code of the power key 45 → 2
Code of channel selection key 22 - 4 - VTR key 48
The code is read out in the order of the code → counter display (CB) -1-34 code → the code of the program search (PS) key 36 → the code of the rewind key 20 and is transferred to the transmitting means 108 at fixed time intervals.

Then, the number N of those codes is counted, and when all the codes have been transferred, the initial state is returned (step 11.1).
2). As a result, remote control operation signals are intermittently emitted from the infrared light emitting diode 110 of the transmitting means 108, and the TV main body and VTR main body receiving these signals demodulate,
It performs signal processing such as decoding, sequentially executes a series of operations in response to a set series of remote control operations, and in the case of the above example, automatically plays back the previous recorded program.

Also, if it is not a function key in step 7,
It is determined that the key is an ordinary key, and the code corresponding to the key input is immediately transmitted to the transmitting means 108 (Step 13).The transmitting means 108 modulates the code with a carrier signal of about 40 KHz and operates the remote control using the infrared light emitting diode 110. A signal is issued (step 14). Then, the device that effectively receives the remote control operation signal executes the operation instructed by the key operation.

Although one preferred embodiment has been described above, various modifications can be made.

For example, the transmitting means 108 may be of a wired type, and the key arrangement on the keyboard 100 can be arranged in various ways. In particular, the order of key operations when performing funk setting is the same as that of the above embodiment. It is not limited to those of.

(Effects of the Invention) As described above, according to the present invention, an arbitrary series of preset remote control operations can be performed by simply pressing one function, so (1) there is no need to repeat a series of troublesome key operations; (2) One touch? ! ! It is very convenient for the elderly as it allows them to perform various operations such as VTR operations.
3) User-friendliness of remote control operations has been greatly improved, such as eliminating the problem of making mistakes when performing a series of key operations in a hurry.
