Abstract

PURPOSE:To operate many devices by a transmitter by providing a transmitter of controlling signals and a receiver that receives signals from the transmitter, displays device or function menu on a television picture, compares the received signal and menu number and outputs controlling signals to each device. CONSTITUTION:In a receiver 6, a device menu as shown in the figure A is displayed on a television by a microcomputer (MC)3 through an output terminal B4. The MC3 compares the device menu displayed on the television 10 at present with received signals, and interprets them as, for instance, 'VTR', and a function menu of VTR as shown in the figure B is displayed, and at the same time, the MC3 stores 'VTR'. On receiving signals from a transmitter 1, the MC3 interprets them as 'VTR, power source ON/OFF' from the received signals and stored 'VTR' and the menu, and turns power source of VTR on through an output terminal A5.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a remote control device that can be used to remotely control a large number of devices such as VTRs and compact disc players in the home.

2. Description of the Related Art A conventional remote control device has a configuration as shown in FIG. was. Therefore, basically one remote control device was required for one device.

However, in recent years, it has become necessary to operate a large number of household appliances such as televisions, VTRs, compact disc players, air conditioners, and electric fans using remote control devices.

In this case, as shown in FIG.
Dedicated remote control devices for each 15b and 15C (receivers 16a, 16b, 160 and television 10.VT
Consisting of R11 and Compact Disc Player 12)
was used. Alternatively, as shown in FIG. 8, one transmitter 16 of the remote control device transmits the television 10. He was operating equipment such as 11 VTRs and 12 compact disc players.

Problems to be Solved by the Invention In such conventional remote control devices, the number of transmitters increases, and it is troublesome to select a transmitter for each device to be operated. There is also a problem that there is a limit to the number of devices that can be operated with one transmitter, or the number of keys on the transmitter increases, and if the number of keys is reduced, the functions that can be operated are limited. .

The present invention has been made in view of this problem, and an object of the present invention is to provide a remote control device that can operate a large number of devices with a single transmitter.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention provides a transmitter that includes a numeric keypad as an input key and transmits a signal corresponding to the numeric keypad, and a transmitter that receives the signal from the transmitter and transmits a signal that corresponds to the numeric keypad. It consists of a receiver that displays the device or function menu on the screen, compares the received signal with the menu number, and outputs control signals to devices such as VTRs and compact disc players.One transmitter can operate many devices. It is a monkey.

Function: With the above-described configuration, the present invention can switch the operation menu each time a control signal is output, and output a different control signal for each menu, and as a result, it is possible to operate a large number of functions of a large number of devices.

Embodiment FIG. 1 is a block diagram showing an embodiment of the remote control device of the present invention. In FIG. 1, 1 is a transmitter of the remote control device, 6 is a receiver, and the receiver 6
is the receiving circuit 2 and the microcomputer 3. Output end 1,000 people 6
．． It consists of an output terminal B4. The output of the receiving circuit 2 is input to the microcomputer 3, and the output of the microcomputer 3 is sent to multiple output terminals A6 and one output terminal B.
4 is input. Figure 2 shows a connection diagram between the remote control device and each device. Output terminal B4 and TV 1o are connected, output terminal 10 is connected to TV 10, VTR 11, compact disc player 12, air conditioner 13. Devices such as an electric fan 14 are connected.

FIG. 3 shows an example of the key arrangement of the transmitter 1 of the present invention, and the keys include a numeric keypad 9 of "0" to "9" and an "input" key 7.
and a "menu" key 8.

Initially, a device menu as shown in FIG. 4 is displayed on the television 1o by the microcomputer 3 through the output terminal B4. So, for example, key "1" of transmitter 1,
When you press ``Input'', the transmitter transmits a signal corresponding to ``1'', ``Input''.

This signal is transmitted using infrared rays, radio waves, or ultrasonic waves, is received by the receiving circuit 2, and then input to the microcomputer 3. The microcomputer 3 compares the received signal with the equipment menu shown in FIG. 4 currently displayed on the television 10, decodes it as "VTR", and displays the VTR function menu as shown in FIG. 5 on the television 1o. At the same time, the microcomputer 3 stores "VTR".

Next, when keys ``2'', ``0'', and ``input'' on transmitter 1 are pressed, the microcomputer reads the received signal, the stored ``VTR'', and the menu shown in Figure 6, ``VT''.
R, deciphered from source o N10 F F-t.

The power of the VTR, which is initially OFF, is turned ON through the output terminal 5.

Next, press the keys °1", 9", and "input" on transmitter 1.
'/TR 11 enters the playback state, and at the same time the menu shown in FIG. 6 disappears from the screen of television 1o, the video of the VTR appears. In this manner, VTR playback is performed by pressing the transmitter key in accordance with the menu screen of the television.

Next, press the "Menu" key 8 on transmitter 1 and TV 1o will be displayed.
The device menu shown in Fig. 4 is displayed again on the screen, and by selecting the device menu number and then the function menu number, you can also select other devices such as the compact disc player 12 in the same way as in "/TH". can be operated.

Effects of the Invention As described above, according to the present invention, a single transmitter can satisfy many functions of many devices, and the number of keys on the transmitter can be reduced. It is extremely useful in practical terms.
