Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control transmitter that is capable of transmitting a plurality of control codes in a predetermined order.

[Conventional technology]

Currently, a remote control transmitter has a single function assigned to its operation button, and when the operation button is operated, the device to be controlled is controlled only once. For example, operating the power button turns the power on or off, and operating the TV/VTR button switches between the TV and VTR.

[Problem that the invention seeks to solve]

However, when playing a VTR using a TV receiver as a monitor, for example, first turn on the TV receiver, then change the TV receiver to video mode, then turn on the VTR, and then turn on the TV receiver. Finally, turn on the VTR.
It is necessary to set it to LAYJ mode.

In this way, depending on the specific purpose, the purpose can only be achieved by performing sequential operations, but with conventional remote control transmitters, it is necessary to perform these operations individually, and improvements have been desired.

The present invention has been made in view of these points, and it is an object of the present invention to provide a remote control transmitter that enables the above-described sequential control with a single operation.

[Means for solving problems]

To this end, the remote control transmitter of the present invention includes a storage means for storing a plurality of control codes as one group, and a shortening box for reading out and transmitting the plurality of control codes from the storage means in a predetermined order. I made it.

〔Example〕

Examples of the present invention will be described below. FIG. 1 is a diagram showing the internal blocks of a remote control transmitter according to an embodiment of the present invention. A program ROM 4 that stores programs or fixed code data, etc., and a work RAM that is used during registration operations.
5. Code data storage RAM 6 for storing registered code data, CG with built-in characters for displaying button functions
ROM7, LCD (liquid crystal display) that displays button functions
8, LCDC9 that controls the LCD8, the LCDC
An image RAM 10, etc., which sends function display data, is connected to 9. 11 is a power supply section, 12 is a synchronization signal generation section, 13 is an oscillation circuit that supplies CLK to each section, and 14 and 15 are interfaces.

FIG. 2 is a diagram showing the operation surface 20 of the remote control transmitter,
The operation surface 20 includes an individual operation section 21, a shortening operation section 22,
A shortened display section 23 is provided.

The individual operation section 21 includes a TV mode button 211, a VT
R mode button 312, multiple operation buttons 213, and its operation button 2
Thirteen function display sections 214 are provided. In addition, the shortening operation section 22 includes shortening boxes 221 to 223, a help button 224,
Display sections 225 to 22 that display shortened boxes 221 to 223
7 is provided.

FIG. 3 is a diagram showing the back side 30 of the remote control transmitter, and the back side 30 is provided with a preset button 31 and a character selection button 32 for selecting a display character.

Now, when the TV mode button 211 is pressed, the entire remote control transmitter becomes for TV control as shown in FIG.
The display is set for V control. On the other hand, when the VTR mode button 212 is pressed, the entire operation becomes for VTR control, and the function display section 214 of each operation button 213 is set for VTR control, as shown in FIG. 2 fbl. These function display sections 214 display the character data read out from the CGROM 7 into the image RAM10 according to the program written in the program ROMd.

Therefore, set it to one of the modes and press the operation button 213.
When one of the buttons is pressed, the code of the function displayed on the pressed operation button is read out from the program R○M4 and sent from the remote control transmitter 3.

Here, a case will be described in which a code for ■RT playback is registered in the shortcut box 221 of the shortcut operation section 22. First, turn on the preset button 31, and then press the assigned shortcut box 221. The character selection button 32 is operated to display "rVTR playback" on the display section 225 corresponding to the shortening box 221. Then, press the TV mode button 211 to set the mode to TV mode, press the r power button, and then press the video button. And this time it's a VTR
Press the mode button 212 to enter the VTR mode (Fig. 2(b)).
), press the "Power" button, and then press 'P.
Press the LAYJ button. As a result, the section corresponding to the above-mentioned shortening box 221 of the shortening display section 23 displays "rTV ON".
, "Video J %' VTR Off J, rVT
"R playback" will be displayed one after another, so check this and then
Finally, turn off the preset button 31.

As a result, the shortening box 2 in the code data storage RAM 6
"rTV on", "Video J, rV on the address corresponding to 21"
The codes of "TR ON" and "rVTR PLAY" are stored as one group in a predetermined order. At the same time, image RA
The rTV is placed at the address corresponding to the shortcut button 221 of Ml0.
"On", "Video", "rVTR On", "rVTR Playback"
display data is stored.

Therefore, if you press the shortcut box 221 after this, the codes will be read from the code data recorder QRAM 6 and transmitted from the remote control transmitter 3 in the order of "rTV on" → rvideo" → rVTR on → r TR playback". Ru. Further, display data of "rTV ON", "VIDEO", "VTR ON", and "rVTR PLAY" are read from the image RAM 10 and displayed in the portion of the shortening display section 23 corresponding to the shortening button 221.

Note that the above is about the case where the shortcut button 221 is provided with a VTR playback function, but the shortcut button 222.2 is also
23 may be provided with other functions such as teletext reception.

After the function is added, the function is displayed on each of the display sections 225 to 227, but its specific content is displayed on the upper abbreviation display section 23 only when the abbreviation is pressed. However, if the help button 224 is pressed, the specific contents of each of the shortcut buttons 211 to 223 are displayed on the shortcut display section 23.

In this case, the code is only displayed and no code is sent.

〔Effect of the invention〕

As described above, according to the present invention, a series of control codes for a plurality of devices for a specific purpose is transmitted by operating one shortcut button, thereby improving operability.
