Universal remote control

The present invention relates to a universal remote controller that allows a manufacturer to conveniently control different device bodies with a single remote control. More specifically, the present invention relates to a memory processor and a microprocessor capable of storing a plurality of TV main body control codes of different manufacturers. It is provided with a reset means capable of initializing the control unit and a control key for them so that the microprocessor of the remote controller can recognize, and a key selection means provided with a manufacturer selection key for selecting each TV maker. The present invention relates to a universal remote controller that allows a manufacturer to remotely control a plurality of different TV bodies by using one remote controller.

In general, the remote control mainly used for VIAL or TV set is a type of integrated remote control (for example, a remote control that can control only Daewoo Electronics' VIAL set and Daewoo Electronics TV set). Since the device is configured to operate only after pressing the Run key, there is a hassle of having to use each remote control individually when there is a VSI or TV set of another manufacturer.

Therefore, in order to improve the inconvenience of using the conventional integrated remote controller as described above, a universal remote controller has been developed that can be controlled by one remote controller even if the VSI or TV set makers are different from each other. They are being developed as a universal remote control according to their needs or their needs.

The conventional universal remote controller includes a power supply unit 50 for supplying operating power to the entire remote controller as shown in FIG. 1, and a key input unit including a power control key for controlling the system main body, a plurality of digit keys, and a manufacturer selection key.

And a light emitting unit 40 which is composed of light emitting diodes and generates an actual key code.

In particular, in the universal remote controller, as shown in the operation flowchart of FIG. 2, the microprocessor 20 stores the TV or VSI key codes of each manufacturer so that the TVs and VSIs of different manufacturers can operate. If the execution key is pressed together with the manufacturer selection key in (10) (Y branch of S22), the execution key code of the corresponding manufacturer is generated (S23), and only the execution key is pressed (Y branch of S24). The key code set in the step of being programmed is generated (S25).

That is, the universal remote controller as described above is a remote controller developed by a certain manufacturer (for example, Daewoo Electronics) to operate the TV of another manufacturer (for example, Sanyo; Sanyo) Sanyo in the key input unit 10 of the remote control After pressing the TV select key, the key code for controlling Sanyo TV can be generated only when the next desired execution key is pressed at the same time. This operation must be repeated every time the execution key is used.

Therefore, in the conventional universal remote controller as described above, if there are Daewoo VSI and Sanyo TV in each home, the remote control is operated by one remote control, and when operating the TV, each manufacturer's selection key and execution key must be pressed at the same time. There was a hassle.

Accordingly, the present invention has been made to solve the above problems, and the present invention provides a memory means capable of storing a plurality of TV main body control codes, a reset means capable of initializing a microprocessor, and control thereof. One remote controller is provided with a key so that the microprocessor can recognize it, and a maker selection key for selecting each TV maker is provided in the key input means, and the corresponding key code generation of the maker is controlled according to the key input state. The purpose of the present invention is to provide a universal remote controller and a control method for allowing a manufacturer to remotely control a plurality of TV bodies different from each other.

Hereinafter, the configuration of the universal remote controller according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a block diagram schematically illustrating a configuration of a universal remote controller according to an embodiment of the present invention.

That is, as shown in the drawing, the universal remote controller includes a power supply unit 50 for supplying operating power to the entire remote controller, a power control key for controlling the system main body, a plurality of digit keys, and a manufacturer selection key. And a key input section 10A provided with a storage key and a reset key and configured to allow the microprocessor to recognize the key input state.

And the manufacturer is provided with a memory unit 70 that can store a number of different body control codes, check the key input unit to determine whether to generate a control code of a different manufacturer from the current, according to the determination result And a microprocessor 20A incorporating a series of control programs for reading and storing the manufacturer's key data from the memory unit and setting it as reference data for execution key code output.

Remote control transmitter 30 for transmitting the key code control signal generated by the microprocessor to the system main body, and a light emitting unit 40 consisting of light emitting diodes to generate the actual key code, the externally selectable It includes a reset switch (60) provided with a set switch (SW1) to initialize the microprocessor according to the user's intention.

Figure 4 is a reference diagram showing a part of the external configuration of the universal remote control according to an embodiment of the present invention, the key input section 10A is a plurality of manufacturers selection keys (AI) in addition to a predetermined position of the key matrix. And a storage key for allowing the microprocessor to store the state when the manufacturer selection key is pressed, and a reset key (SW1) for initializing the microprocessor (20A). It is shown.

FIG. 5 is a flowchart illustrating a control process of the universal remote controller according to the present invention. FIG. 5 is a diagram illustrating a control program embedded in the microprocessor of FIG. 3.

That is, in the drawing, the control program checks whether the manufacturer selection key and the storage key are continuously input through the key input unit (S211-S213), and if the manufacturer selection key and the storage key are continuously input as a result of the check. The second step (S216) of storing the state and reading the key data of the manufacturer selected above from the memory unit and setting it as reference data at the time of generation of the key code for the execution key input, and the reset key through the key input unit When inputted, the third step (S217-S220) initializes the currently stored key data, reads and stores the key data of the first manufacturer from the memory unit, and sets it as reference data when the key code is generated for the subsequent execution of the key input. It is shown.

In this case, if the manufacturer selection key is input in the first step and the memory key is not continuously input, and the execution key is input again, a processing step (S214-S215) of generating a key code of the manufacturer that is previously stored by the manufacturer is included. It is also preferable to.

The operation of the present invention as described above is as follows.

First, the microprocessor 20A of the remote controller checks whether the manufacturer selection key and the storage key are continuously input through the key input unit 10A (S211-S213), and when the manufacturer selection key and the storage key are continuously input (S213). Y branch) Recognizing the state, the key data of the manufacturer selected above is read from the memory unit 70 and stored (S216), and when the execution key is input (Y branch of S217) to the stored execution key of the manufacturer. The corresponding key code is generated (S218).

However, in this case, when the manufacturer selection key is input in the first step, when the memory key is not continuously input and the execution key is input again (Y branch of S214), a process of generating a key code of the manufacturer that has been previously stored by the manufacturer is stored. Process S215 is executed.

When the microprocessor 20A subsequently checks the key input unit 10A again (S217, S219) and determines that the reset key is input (Y branch in S219), the microprocessor 20A initializes the currently stored key data. By performing the operation of reading and storing the key data of the preferred manufacturer from the memory unit 70 and setting the key data as reference data when the key code is generated for the subsequent execution key input, the remote controller is initialized even after the manufacturer selection key is not input. You will be able to execute the functions you have.

That is, for example, if the TV key code of each manufacturer is stored in the memory unit 70 using the Daewoo VSI remote controller, and then the Sanyo selection key of the key input unit 10A is to be used when the TV produced by Sanyo is used. When the memory key is pressed, the microprocessor 20A reads and stores the Sanyo TV's key code stored in the memory unit 70. When the execution key is input, the microprocessor 20A generates a code corresponding to the Sanyo TV's execution key. Each time you press, you can control Sanyo TV automatically without pressing the Sanyo Select key each time.

In addition, if the TV is changed to that of another manufacturer (for example, Daewoo) while using the Sanyo TV as described above, by pressing the reset key to initialize the microprocessor of the remote controller, the stored Sanyo TV keycode can be deleted. At the same time, it reads and memorizes key data (ie, the remote control made by Daewoo Electronics, which can be the first priority), so that Daewoo TV can generate key codes in the case of subsequent execution key input. do.

In addition, if you want to use the TV of another manufacturer (for example, Philips) after inputting the reset key, press the Philips selection key and then press the memory key to output the key code of the manufacturer as in the above case. It becomes possible.

According to the present invention as described above, even if there are several TVs in each home, one VSI remote controller automatically stores the TV keycode of the corresponding manufacturer whenever the user enters an execution key. As a result, the remote controller can be used conveniently without cumbersome key operation.
