The present invention relates to a transmission and reception remote control device, and more particularly, to an input data display device and a method of a transmission and reception remote control for displaying the current information state while operating the system in the remote control unit.

In general, the remote control device operates a remote control key because the system is configured to display important information for the user in a recording medium such as a digital audio tape or a compact disc when the system is operated from a remote location by operating the remote control key. There was a problem that can not accurately recognize the information displayed on the system at the location.

Accordingly, an object of the present invention is to provide an input data display apparatus and method for transmitting and receiving remote control for displaying the important information of the system by remote control key operation so that the remote control can be recognized using a modulation signal generated inside the microcomputer.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 is a circuit diagram of an embodiment according to the present invention, a system for controlling a system by inputting a remote control unit 10 for generating a remote control signal by remote control key selection and a remote control signal of the remote control unit 10. It consists of a part 20.

In the above configuration, the remote controller 10 includes a microcomputer 11 for controlling the remote controller, a key signal input by remote controller key selection, a key input unit 12, and a key signal of the key input unit 12 to input the key signal. The remote control signal transmission unit 13 which transmits a key signal under the control of the microcomputer 11, and inputs a remote control signal from the system transmission number 24 of the system unit 20 to convert the digital key data into the microcomputer 11 And a display unit 15 for inputting a control signal from the microcomputer 11 to display the received information. The system unit 20 includes a modulation pulse output unit for outputting a modulation pulse. A system microcomputer 21 for controlling the system, and a system receiver 22 for inputting a remote control signal from the remote control transmitter 13 to convert the digital key data into a digital key data and outputting the digital key data to the system microcomputer 21; ), And the microcomputer 21 And a system transmitter 24 for inputting the modulation pulse signal of the modulation pulse output unit 23 to transmit the information signal of the system under the control of.

2 is a flow chart of an embodiment according to the present invention, in which a key signal is input from the remote controller 10 so that only the system is driven when the key data does not require information, and the remote controller 10 in the first process. The second step of transmitting desired information from the system transmitter when the key input signal of the current controller requests current status information, and the remote controller key from the remote controller 13 when the key signal of the remote controller 10 is inputted and does not request information. A third process of transmitting only data, and when a key signal of the remote controller 10 is inputted in the third process to request information, the controller receives the information transmitted from the system transmitter 24 and controls the remote controller microcomputer 11. A fourth process is displayed on the display unit 15.

Based on the above-described configuration, an embodiment of the present invention will be described in detail with reference to FIGS.

First, when a key signal is input by selecting the remote control key signal from the key input unit 12, the remote control signal is transmitted from the remote control unit 13 under the control of the microcomputer 11. The system receiver 22 for inputting a remote control signal from the remote control transmitter 13 converts and outputs a key signal in the form of digital data. When the key signal converted into the digital data form by the system receiver 22 is input to the system microcomputer 21, the system performs an operation. At this time, when the display request information signal is present, the modulation pulse output unit 23 of the system microcomputer 21 outputs the modulation pulse to the system transmitter 24 so that the system transmitter 24 transmits the information signal of the system unit 20. Send. The remote control receiver 14 receiving the system information signal from the system transmitter 24 converts the signal into a digital conventional signal and outputs the signal to the remote controller microcomputer 11. This causes the display unit 15 to display the information content of the current state under the control of the remote controller microcomputer 11. Therefore, the display method as described above is described in the flowchart of FIG. 2 (a) (b). In step (a1), it is determined whether the key signal of the key input unit 12 has been input, and if the key signal is input, step (a2) is performed. In step (a2), the key input unit 12 determines whether there is an information request key, and if there is no information request key, only the system is driven in step (a3), and if there is an information request key, step (a4) is performed. In step (a4), the modulation pulse of the modulation pulse output unit 23 inside the microcomputer is output, and the system transmitter 24 transmits desired information and performs step (a5). In the step (a5), the system transmitter 24 determines whether the information transmission is finished. If the transmission is not completed, perform the step (a4) to continue transmitting the request information, and when the transmission is completed, the transmission is terminated.

In addition, in step (b1), it is determined whether a remote control key input signal is input, and if a key is input, step (b2) is performed. In step (b2), it is determined whether there is an information request key. If there is no information request key, in step (b3), only the key signal input from the key input unit 12 is transmitted to the system, and if there is an information request key, step (b4) is performed. . In step (b4), the remote controller micom 11 prepares for reception, and in step (b5), the remote controller receiver 14 receives information transmitted from the system transmitter 24 and performs step (b6). In the step (b6), it is determined whether the reception is finished, and if the reception is not completed, the operation is continued by performing the step (b5). If the reception is completed, the information is displayed on the display unit 15.

As described above, the system can be operated by remote control key operation and at the same time, important data of the recording medium can be displayed and recognized in the remote control at any position.
