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

FIG. 1 is a block diagram showing a function display apparatus of an optical disk player according to a preferred embodiment of the present invention, in which a function display apparatus 100, a memory 110, a microcomputer 120, a key input unit ( 130, the OSD processing unit 140, and the optical disc player 200.

Referring to the functions for each block of the component shown in FIG. 1, first, the memory 110 includes data on function keys that can be used in each mode provided in the optical disk player and use of each function key. The description data is stored.

The microcomputer 120 detects a key signal input from the key input unit 130, controls the operation of the optical disc player according to each key signal, detects the operation mode of the optical disc player, The OSD processing unit 140 is controlled so that the data of the usable key or the usage description data according to the selection key signal is withdrawn from the storage unit 110 and the extracted data is OSD processed.

The key input unit 130 includes a plurality of keys such as a function confirmation key, a numeric key, a direction key, and generates a key signal corresponding to each key according to a user's key input.

The OSD processor 140 outputs data drawn from the memory 110 under predetermined control information on the OSD screen under the control of the microcomputer 120.

Hereinafter, an operation process of the volume display device made of the above-described constituent members will be described in detail.

2 is a flowchart showing a function display method of an optical disc player according to a preferred embodiment of the present invention.

First, when a user inserts a disc deck to be played, the optical disc player 200 loads a disc to read information of a table of content (TOC) in a load-in section of the disc. After (S 1), a key signal is generated in the key input unit 130 through a key input as desired by the user, the microcomputer 120 detects a key signal from the key input unit 130, the optical disk player A control signal for controlling the operation of 200 is generated.

By the control signal from the microcomputer 120, the optical disc player 200 operates in a mode desired by the user (S 2).

On the other hand, when the user presses a function check key provided in the key input unit 130 to check the currently available function keys to use any other function during the operation of step 320, the key input unit 130 generates a function check key signal Then, the microcomputer 120 detects a function confirmation key signal and generates a control signal to the optical disk player 200 to stop the operation of the currently operating optical disk player (S 3).

The optical disc player 200 is stopped by the control signal from the microcomputer 120 (S4), and the microcomputer 120 detects an operation mode in which the optical disk player 200 is operating before stopping again. After (S5), the data of the function key usable in the operation mode detected in S5 is withdrawn from the memory 110 (S6) and the OSD processing unit 140 is controlled to perform OSD processing.

Under the control of the microcomputer 120, the OSD processor 140 outputs the data drawn from the memory 110 to the OSD screen as predetermined information characters.

At this time, the OSD screen of S 7 outputs the information of the function keys available in the mode immediately before being stopped by the function confirmation key signal among the plurality of modes provided by the optical disc player, and also the multiple functions displayed on the OSD screen. One function key of the key is inverted and output on the OSD screen. Accordingly, the user can select a desired function key on the OSD screen by pressing a direction key or a numeric key provided on the remote controller or the key panel.

Thereafter, in S 7, the microcomputer 120 detects whether the selection key signal is input from the key input unit 130 (S 8), and if there is no input of the selection key signal, detects whether the function key signal is input. )

Meanwhile, when the selection key signal is input from the key input unit 130 in S 8, the microcomputer 120 extracts the description data of the function key corresponding to the selection key signal from the memory 110 (S 9) and outputs the OSD. Control 140.

Under the control of the microcomputer 120 in S 9, the OSD processor 140 outputs data drawn from the memory 110 to the OSD screen as predetermined information characters.

In this case, a description of the usage of the function key selected in S 8 is output on the OSD screen of S 10.

Subsequently, when a function key signal from the key input unit 130 is input (S 11), the microcomputer 120 releases the function check mode and the control signal so that an operation corresponding to the function key signal can be performed in the optical disc player. To generate (S 12).

As described above, according to the present invention, the function keys available in each mode of the optical disc player and the description of each function key can be checked on the monitor by the key operation of the key input unit, and thus the functions provided in the optical disc player are used. This has the effect of increasing convenience and efficiency.
