The present invention relates to a remote control device using an RF signal that enables control.

In general, when a house is divided into a living room, a bedroom, a small room, and a kitchen, most of the TVs are installed in the living room, and most of the homes and children's rooms are separately installed.

In such a situation, a separate setup box is installed and a video output signal of the setup box is connected to two or more TVs through a splitter for reasons such as content use and digital broadcasting viewing by an interactive service. As shown in (A), the TV 4 and the setup box 6 are installed in the living room, and the setup box is installed when watching a broadcast provided by the setup box company while being connected by the connecting line 3. The TV can be used to change channels, adjust volume, and change other functions with the remote control (5) .However, if you operate the setup box remote control (2) to watch a program provided by the receiver company on a TV screen (1) covered by a wall, Infrared signal does not reach the setup box (6).

Therefore, at present, the viewer is inconvenient to move to the living room and select the desired program with the receiver remote controller 5 or to finish the other operations and come back to the room to watch again.

The present invention is devised to solve the above-mentioned shortcomings, and has an infrared receiver and has an RF remote control having a learning ability to receive and store the infrared signal of the existing setup box and the TV remote control and convert it into an RF signal. By providing RF remote control by learning more various types of remote controllers and using RF signals, regardless of obstacles such as walls, the remote controller can be conveniently used anywhere in the house. For the purpose.

In order to achieve the above object, the present invention provides a TV remote control, comprising: an infrared receiver for receiving an infrared signal and a caste code of a device to be learned, and an infrared signal and a caste code received from the infrared receiver and a user ID; A control unit for controlling the signal stored in the storage unit, and converting the signal stored in the storage unit into an RF signal, an RF signal transmitter and antenna for transmitting the changed RF signal from the control unit, and allowing the user to control the setup box with a remote controller. An RF remote controller comprising a key input unit; An antenna and an RF receiver for receiving an RF signal transmitted from a remote controller, a user ID storage unit for storing the user's ID, an RF signal received from the RF receiver and an RF signal received from the RF receiver are analyzed and compared with the user ID.

Hereinafter, the configuration and the operation of the embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The present invention, as shown in (B) of FIG. 1, when a viewer operates a button with an RF remote control in front of the TV, the signal is transmitted by RF, and the RF receiving infrared transmitting device located outside the obstacle receives the radio wave and the infrared ray is set in the setup box. It is a device that can control the setup box by sending out the key value received as a signal.

In other words, the infrared remote controller does not work even if there is a wall or other obstacles, so the signal is inputted to the wireless RF remote controller that can go beyond such a barrier, and then the control signal is transmitted as an RF signal using the RF remote controller. The signal is to be received by the infrared transmitter near the controller to control the setup box.

On the other hand, the radio frequency communication is used to insert a 4-byte user code into the transmission data header so as not to cause problems to other devices using the same frequency, thereby preventing malfunction.

In addition, the present invention does not have two bytes of the caste code used for controlling each home appliance and the infrared remote controller, so that the user can directly register with the infrared remote controller.

On the other hand, by storing the castum code of the various devices in advance in the storage unit of the RF remote control, it is possible to select and control the RF remote control to omit the infrared receiver to reduce the manufacturing cost of the RF remote control.

Figure 2 is a block diagram showing the internal configuration of the RF remote control capable of remotely controlling the infrared control device of the present invention, Figure 3 is a block diagram showing the RF receiving infrared control signal generator.

The RF remote control is equipped with an infrared receiver for receiving and registering 2 bytes of the castom code of the device or receiving and storing control signals of each key of the infrared remote controller, and various calculations and control such as reading this value or reading the key value pressed. And a control unit for performing a key, a key input unit for inputting a key, a storage unit 17 for storing a castum code and a user ID of the device, an RF transmitter, and an antenna.

When using the RF remote control for the first time, use the infrared receiver to register and receive 2 bytes of the caste code of the remote control that transmits the infrared control signal, or the user directly receives the infrared signal to the RF remote control from the infrared remote control, The learning process of storing the control signal for the key in each key input unit of the RF remote control is performed.

The input signal is transmitted together with the user ID and the castum code to the RF signal and transmitted to the RF receiving infrared signal transmitter, and the received RF receiving infrared signal transmitter interprets it and sends the signal to the setup box or the infrared controller for control. Do it.

On the other hand, the infrared receiver of the RF remote control is removed, and the caster code of the remote controller being used in the market and the control signal for the caster code are input to the storage unit in advance, and various caste codes can be selected from the key input unit of the RF remote controller. By making the infrared receiver removed, the manufacturing cost can be lowered. The stored castum code can be updated later.

3 is an RF receiving infrared control signal generator, and includes an antenna for receiving an RF signal from an RF remote control unit, an RF receiving unit, a control unit for various operations and control, and a user ID storage unit. 4 bytes of ID, 2 bytes of device castum code, 1 byte of button value, and nucleus OFFH-The value of the button indicates the RF remote control device that controls the setup box or the infrared actuator by emitting an infrared LED.

4 is a schematic diagram of communication between devices according to the present invention, in which the RF receiving infrared transmitter is placed in front of a setup box or other controller on the B side divided by a separating wall, and pressing the RF remote control on the A side, the control unit via the key input unit. Reads and reads 4 bytes of user ID, 2 bytes of device castum code and 1 byte of control signal from the device caste code and user ID storage unit, and transmits the antenna radio wave through the RF transmitter, and the antenna and RF receiver of the RF receiver infrared signal transmitter. Reads 4-byte value pre-registered in the user ID storage unit and compares it with the user ID sent from the RF remote control, and if it is the same, 2 bytes of castum code, 1 byte of button value, nucleus OFFH-button value through the infrared transmitter. Infrared LED can be used to control the setup box or the infrared actuator.

FIG. 6 is a flowchart illustrating an operation of the RF remote control. As shown in FIG. 6, the operation of the RF remote control is read. First, the user ID is read into 4 bytes of user ID and 2 bytes of manufacturer's castum code in order to set an initial value.

After that, after reading the key value, if the key is pressed, it is checked whether the pressed key is the castum setting key.

When the caste setting key is pressed, the RF remote control waits to receive a signal from the infrared device, receives the caste code from the infrared receiver, and stores 2 bytes of the manufacturer's caste code.

When the castum setting key is not pressed, a signal corresponding to the pressed key is transmitted as an RF signal, and 4 bytes of a user ID and 2 bytes of a manufacturer's castum code are transmitted together with the RF signal.

On the other hand, the infrared receiver can be omitted by inputting the castum code and the control signal for the code in advance to the storage unit and setting the selection of the castum code in the RF remote control. This reduces the selection of a variety of remote control, but has the advantage of lowering the manufacturing cost by omitting the infrared receiver.

 FIG. 7 is a flowchart illustrating an operation of an RF receiving infrared signal transmitter. As shown in FIG. 7, after reading RF reception data in an initial state and checking the presence or absence of received data, the received data is stored again if it returns to the receiving operation. The reception ends after that.

After the reception is completed, if the user ID of the stored received data and the value of the initial stored user ID are the same, the setup box is controlled by transmitting a signal suitable for the received data as an infrared signal.
