Abstract

PURPOSE: A VCR system having a displaying function for the operating mode of a VCR is provided for a user to conveniently check the operating state of a set side by displaying the present operating mode of the VCR set on the displaying unit of a remote controller. CONSTITUTION: A user inputs a certain function key by using the key inputting unit of a remote controller for operating a function in a VCR system. A certain functional key signal is fed to a remote controller microcomputer. Herein, the remote controller microcomputer transfers a controlling signal to a first generating unit for transferring a controlling code of function according to the input of the functional key as an optical signal. Then, the optical signal transferred from the first generating unit is received by a first receiving unit of the VCR set for converting the received optical signal into a certain signal to be transferred to a system controlling unit. After operating the operating mode of the VCR set, the system controlling unit transfers the information signal of the operating mode of the set to a second generating unit. Then, the second generating unit converts the information signal into an infrared ray optical signal for transferring to a second receiving unit of the remote controller. And, the second receiving unit converts the received optical signal into a certain signal to transfer to the remote controller microcomputer. Herein, the remote controller microcomputer controls a displaying unit to display the state of the operating mode of the VCR set.

Remote control system with operating mode display function of VSIAL

The present invention relates to a VSI system having an operation mode display function of a VSI, and more particularly, to display a current operation mode of a VSI set on a display unit of a remote controller, thereby allowing a user to conveniently check the set side operation state. A VSI system having an operation mode display function is provided.

In general, the remote controller 10 includes a power supply unit 11 for supplying operating power to the entire remote controller as shown in FIG. 1, a power on / off key and a digit key of 0 to 9 for an interface with a user. The key input unit 12 having a plurality of function keys for setting a unique function for each of the key input unit 12 and a key input unit 12 operated by the power supplied from the power supply unit 11 in a state of being communicatively connected to the system control unit of the main body. Check the key input signal selected by the user through the input unit to determine the key input state and generate a signal to generate a control pulse corresponding to the key input signal 13 and the control pulse output from the micom The light emitting unit 14 emits light and transmits a control signal to the system control unit of the main body.

In addition, the system main body 20 receives a key control signal transmitted from the light emitting unit 14 of the remote controller and outputs it to the control unit, and judges the data transmitted from the light receiving unit 21, such as reservation recording. A system control unit 22 for generating an OSD control signal for generating a guide character, and an OSD processing unit 23 for generating a character designated by the system control unit, mixing it with an image signal supplied from an image processing unit, and then outputting it to an image signal output terminal. I include it)

In the conventional remote controller operation, the remote controller micom 13 is always in the standby state by the power supplied from the power supply unit 11, and the user selects a desired key through the key input unit 12 by checking the key input state. Then, the remote controller micom 13 checks the key input state to determine the corresponding control function, and generates a control pulse to control the light emitter 14 according to the determination result, thereby to the VCR main body through the light emitter 14. Transmit control signals to control the various functions in the main body

On the other hand, when the system main body 20 receives the key control signal transmitted from the light emitting unit 14 of the remote controller from the light receiving unit 21 and outputs it to the system control unit 22, the system control unit 22 at the light receiving unit 21 By judging the transmitted data, the OSD processor 23 controls OSD processing unit 23 to generate OSD characters, synthesize or switch the video signal, and configure a guide screen such as a reservation recording.

However, if the user wants to know the current operating mode of the operating system as described above, there is a hassle of having to go through the menu to check the setting state after outputting the OSD screen to the CRT unit by operating the remote controller. .

Some models display the current operation mode of the VSI set through a digitron provided at a predetermined portion on the front side of the VSI set, but this is not applicable to all models, too.

Accordingly, the present invention is to solve the above problems, V to display the current operating mode of the V-set to the display unit of the remote control to enable the user to conveniently check the operating state of the V The purpose is to provide a sial system.

In order to achieve the above object, the present invention provides a remote control system having a function of transmitting a predetermined infrared light signal under the control of a remote controller microcomputer to provide a key input unit for interface with a user so as to communicate with a system control unit of a main body. And a first transmitter for transmitting a key input signal under the control of the remote controller micom as an optical signal carrying predetermined control code information, and receiving the optical signal transmitted from the first transmitter to the corresponding control code information. A first receiver to convert the first control unit to the system control unit, a second transmitter unit for receiving the current set of operation mode information from the system control unit, converting the signal into an optical signal, and transmitting the optical signal to the remote controller unit; A second receiver which receives an optical signal and sends the predetermined signal to the remote controller micom and received from the second receiver; The display unit may include a display unit which displays the operation mode information of the current main body set under the control of the remote controller microcomputer.
