That is, when a signal for controlling the output of video or audio signals and other functions by the user is applied to the remote controller 20, the second microcomputer 5 of the remote controller 20 transmits the corresponding data to the VTR main body 10. In order to output the data to the light emitting diode 26. Accordingly, the light emitting diode 26 emits light and outputs data to the VTR main body 10.

Should be handled. In this case, the audio signal is illustrated as being output through the headphones of the remote controller. The data output from the audio output unit 4 is output to the RF (high frequency) modulator 5 to be modulated and transmitted through the transmitter 6. It is applied to the receiver 21 of the remote control 20. When the audio signal is applied to the receiver 21, the second microcomputer 25 controls the remote controller 20 to output the audio signal to the headphones attached to the remote controller through the demodulator 22 and the amplifier 23.

As shown in the figure, the VTR main body 30 of the present invention includes a remote control data receiving unit for receiving output data of the remote control 40 generated from the light emitting diode LED2 of the remote control 40 in the conventional VTR main body of FIG. 39 and the optical data of the remote controller 40 by selecting the optical data of the remote controller 40 by preventing crosstalk between the optical data coming through the remote controller data receiver 39 and the optical data generated from the light emitting diode LED1 of the VTR main body 30. A first bandpass filter 38 for transmitting the received data from the first microcomputer 31 to the first microcomputer 31,

The remote controller 40 according to the present invention, which can confirm the operation mode of the VTR, receives the data indicating the operation mode state of the VTR generated from the VTR main body 30 to the remote controller 20 configured as shown in FIG. 1B. And preventing the crosstalk between the optical data input to the light receiving unit 47 and the optical data generated by the remote controller 40 itself, and selecting only the optical data applied from the VTR main body 30 to transfer to the second microcomputer 49. If key data is not input from the two-pass filter 48 and the key 45, the data to be applied is checked while maintaining the standby state for a predetermined period of time.

3A and 3B are flowcharts for performing the VTR operation status check according to the present invention. FIG. 3A is a control flowchart performed by the first microcomputer 31 in the VTR main body 30, and FIG. 3B is a remote controller 40. Is a control flow chart performed by the second microcomputer 49 of FIG.

The operation of FIGS. 2A and 2B will now be described in conjunction with FIGS. 3A and 3B.

When the user inputs the first mode confirmation key data signal for confirming the operation mode through the key 45 to the second microcomputer 49 (step 58), the second microcom 49 outputs the mode confirmation data to the LED. Data is output to LED2 (step 59). Accordingly, the light emitting diode LED2 transmits mode confirmation data to the remote control data receiving unit 39 of the VTR main body 30.

The remote control data receiver 39 of the VTR main body 30 receives the mode confirmation data for mode confirmation from the remote controller 40 and provides it to the first band pass filter 38, and the first band pass filter 38 Is filtered and applied to the first microcomputer 31. If the mode confirmation data applied from the first bandpass filter 38 is the first mode confirmation data, the first microcomputer 31 checks whether the video tape is mounted on the current video tape recorder and checks the current time to display the data. The light emitting diode LED1 is output to the light emitting diode LED1 and the light emitting diode LED1 is converted into an optical signal and provided to the remote controller 40 (steps 51 and 52). Accordingly, the light receiving unit 47 of the remote controller 40 receives data indicating whether the video tape output from the light emitting diode LED1 is mounted and the current time and provides the data to the second band pass filter 48, and the second band pass filter. 48 filters it and passes it to the second microcomputer 49. The second microcomputer 49 outputs whether the video tape is mounted on the liquid crystal display 50 and the current time data so that the video tape applied through the second band pass filter 48 can be displayed and the current time can be displayed. (Step 60).

After this process, the second microcomputer 49 of the remote controller 40 checks whether mode key data for controlling the operation mode of the VTR main body 30 is applied through the key 45 (step 61). If it is recognized that the mode key data for controlling the operation mode is not applied, the second microcomputer 49 enables the counter operation of the second counter 46 to maintain the standby state for the input data for a predetermined time. . At this time, the second microcomputer 49 compares the preset value set in advance for a predetermined time with the count value of the second counter 46 to continue counting when the count value is smaller than the set value, and the count value is larger than the set value. If equal, the control is reset to reset (step 62, 63, 64).

When mode key data for controlling the operation mode of the VTR main body 30 is applied through the key 45, the second microcomputer 49 may allow the VTR main body 30 to perform a function corresponding to the mode key data. The control signal is output to the VTR main body 30 through the light emitting diode LED2, and at the same time, data for confirming the operation mode of the VTR main body 30 is output to the VTR main body 30 through the light emitting diode LED2. (Step 65).

The remote control data receiver 39 of the VTR main body 30 receives mode key data for controlling the operation mode and mode confirmation data for confirming the operation mode of the VTR main body 30 and transmits the result to the first band pass filter 38. The first band pass filter 38 filters the first band pass filter 38 and applies it to the first microcomputer 31. The first microcomputer 31 continuously inputs the mode key data and the mode confirmation data from the first band pass filter 38 to allow the VTR main body 30 to perform a function corresponding to the mode key data. Step 53 and 54), the state of the operation (or execution) mode currently being performed in the VTR is checked and output to the light emitting diode LED1. The light emitting diode LED1 provides data to the light receiving unit 47 of the remote controller 40 indicating the operation state currently being performed at the VTR main body 30, and the light receiving unit 47 receives the second band pass filter 48. ) Is applied to the second microcomputer 49 (step 66). Accordingly, the second microcomputer 49 outputs data so that the operation state currently being performed in the VTR main body 30 can be displayed through the liquid crystal display 46 (step 67).

At this time, when the mode key data is not applied through the remote controller data receiver 39, the VTR main body 30 controls the function of the first counter 37 like the second counter 46 of the remote controller 40 for a predetermined time. In step 55, 56, and 57, the standby state is maintained for the data applied from the remote controller 40.

As described above, the present invention enables the current operating mode state of the VTR main body to be confirmed through the liquid crystal display of the remote controller, thereby enabling the current state of the VTR to be checked on the remote controller without driving the VTR main body.
