Recording media such as an optical disk having a large recording capacity have been developed, and data having a large capacity such as a movie can be recorded on one optical disk. Generally, a DVD-R (Digital Video Disk-Read), which is an optical disk player, is recorded only once and subsequently reproduces the recorded data. An optical disc recording and reproducing apparatus for recording, erasing and rewriting data on an optical disc such as a DVD includes DVD-RAM, DVD-RW, DVD + RW, and the like.

At present, such an optical disc recording and reproducing apparatus reproduces the data recorded on the magnetic tape and integrates the VCR device for recording the data on the magnetic tape into a single integrated system in the DVD apparatus.

By the way, the optical disc recording and reproducing apparatus provides a user interface oriented OSD menu screen for setting the function of the system during recording or reproduction. The OSD menu has a sequential or tree structure that goes from large classification to small classification.

Accordingly, the user selects the menu key to select the audio volume during recording, selects the menu screen when recording from the main screen displayed on the display, selects the desired audio volume setting on the recording menu screen, and then selects an arbitrary volume size. I'm typing. This sequential menu setting method has a disadvantage that it takes a very long time.

To this end, a separate hot key or hot key is provided on the remote controller, and when the key is pressed, the optical disc recording and playback device immediately displays an OSD menu screen corresponding to the corresponding key.

However, if a separate hotkey or hotkey is provided on the remote control, there is a problem of excessive key abuse. Furthermore, a hotkey or hotkey for selecting an OSD menu which is frequently used in an optical disc recording and playback device having a combination of two or more systems is combined. There was a problem to be provided with a plurality.

An object of the present invention is to solve the problems of the prior art as described above, by dividing each setting function of the OSD menu into codes, when a user inputs a code of a desired setting function, the OSD menu screen corresponding to the corresponding code is immediately displayed. The present invention provides a menu code input method of an optical disc recording and reproducing apparatus that can increase user convenience.

In order to achieve the above object, the present invention provides a method of outputting an OSD main menu screen displayed as a code for distinguishing each setting function of a pre-stored OSD menu when a menu key and a specific key are input, and a specific code of the OSD main menu screen. Providing an OSD submenu screen corresponding to a code when a specific key is input, and setting a control function of a device corresponding to the setting value when a setting value of each setting menu in the OSD submenu screen is input. It includes a step.

The control unit 18 controls the overall components of the optical disc recording and reproducing apparatus. In the present invention, when a menu key and a specific key are input from the key input unit / remote control receiver 22, the OSD stored in the OSD menu code storage unit 20 is stored. The numeric or character code for distinguishing each setting function of the menu is transmitted to the OSD generator 48, and the OSD generator 48 generates the OSD main menu screen indicated by the code and provides it to the video output 46. . When a specific code and a specific key are input from the key input unit / remote control receiver 22, the controller 18 transfers the OSD submenu information corresponding to the corresponding code stored in the memory (not shown) to the OSD generator 48. The OSD generating unit 48 controls to generate the OSD submenu screen of the corresponding setting function and provide the OSD submenu screen to the video output unit 46. In addition, the controller 18 controls to set a control function of a device corresponding to the setting value when one setting value of each setting menu in the OSD submenu screen is input from the key input unit / remote control receiving unit 22.

The OSD menu code storage unit 20 stores numeric or character codes that distinguish setting functions of the OSD menu of the optical disc recording and reproducing apparatus.

The key input unit / remote control unit 22 receives a signal received from a key button or a remote controller of the optical disc recording and reproducing apparatus and provides it to the controller 18.

The decoder 24 decodes a video image input through a TV, a VCR, or an external device (camcorder, etc.) and delivers it to the packet video encoder 28. The ADC 26 converts the audio input through a TV, a VCR, or an external device (camcorder, etc.) into digital and delivers it to the audio encoder 30.

The packet video encoder 28 encodes the packet video signal to a multiplexer 32 by encoding the packet video signal using a compression algorithm such as MPEG-2. The audio encoder 30 encodes the audio signal using a compression algorithm such as AC-3 and delivers the audio signal to the multiplexer 32.

The multiplexer 32 multiplexes each signal of the packet video encoder 28 and the audio encoder 30 and delivers them to the error correction coding unit 34.

The error correction coding unit 34 inserts an error correction code into the data of the multiplexer 32 and transmits the error correction code to the optical pickup unit 14.

The error correction unit 36 extracts an error correction code from the data reproduced by the pickup unit 14, checks whether the error correction code is correct, and provides it to the demultiplexer 38.

The demultiplexer 38 demultiplexes the data of the error corrector 36 into a video signal and an audio signal, passes the separated video signal to the packet video decoder 42, and transmits the separated audio signal to the audio decoder 40. To pass.

The audio decoder 40 decodes the audio signal separated by the demultiplexer 38 by using an AC-3 decompression algorithm, and delivers it to the DAC 44. The packet video decoder 42 transmits the video signal separated by the demultiplexer 38. Decoded by a decompression algorithm such as MPEG-2 and transmitted to the video output unit 46.

The DAC 44 converts the audio signal decoded by the audio decoder 40 into an analog and outputs it to a speaker or the like, and the video output unit 46 processes the decoded video signal by the packet video decoder 42 to TV or Output to a monitor, etc.

The OSD generator 48 generates an OSD main menu screen by using a number or a letter code to distinguish each setting function of the OSD menu stored in the OSD menu code storage unit 20 under the control of the controller 18. The output unit 46 is provided. The OSD submenu of the corresponding setting function is generated using the OSD submenu corresponding to the specific code and provided to the video output unit 46.
