Description

Music input / output device and input / output method of optical disc player

The present invention relates to a music input / output device and an input / output method of an optical disk player, and more particularly, a character input when playing a corresponding song after briefly inputting a song recorded on an optical disk such as a DVD (Digital Versatile Disk). The present invention relates to a music input / output device and an input / output method of an optical disc reproducing apparatus.

In general, an optical disk such as a compact disk (CD), a laser disk (LD), a video compact disk (VCD), a DVD, or the like is a storage medium that is made so that data such as audio or video is recorded in a predetermined effective area and reproduced therefrom. In addition to being robust, the recorded data is not easily damaged, and the utilization thereof is gradually increased because of the advantage that it can be reproduced cleanly without noise using a light beam.

FIG. 1 is a schematic block diagram for explaining a general optical disc player, and its configuration is as follows.

The disc motor 1 rotates the optical disc 2 mounted on the deck to be reproduced.

The optical disc 2 is largely divided into three area signal areas, that is, a lead-in area, a program area, and a lead-out area, each signal area being the center of the optical disc. It has data in the form of a projection called a pit along a track that is spirally wound from the outside to the outside.

The lead-in area is commonly referred to as a table of contents (TOC), such as the type of optical disc, the number and size of programs stored on the optical disc, the address of each program, i.e. the position on the optical disc, the start time of each track, the total playback time of the optical disc, and the like. It has data called

The program area has substantial program data, and the lead-out area has data indicating the end of the program.

The objective lens 3 focuses the light beam on one surface of the optical disc 2 and receives the reflected light beam.

The optical pickup 4 converts the light beam incident by the objective lens 3 into an RF signal and outputs the RF signal.

The RF amplifier 5 amplifies the RF signal input from the optical pickup 4 to a predetermined level and performs waveform shaping.

The signal processor 6 converts an RF signal input from the RF amplifier 5 into a digital signal under the control of the controller 7 to be described later, and then outputs the processed signal.

The control unit 7 stores various information about the optical disc 2 output through the signal processing unit 6 and controls the overall operation accordingly, and in response to the tracking error signal output through the RF amplifying unit 5 A signal for focusing adjustment is output in response to a signal for tracking adjustment and a focus error signal.

The information of the optical disc 2 recorded in this control unit 7 is stored only while the optical disc 2 is mounted on the deck, and the information of the recorded optical disc 2 is lost when the deck is opened to replace the optical disc.

The motor driver 8 outputs a drive control signal so that the motor 9 is driven by the tracking adjustment signal and the focusing adjustment signal input from the control unit 7.

The decoder 10 restores an image signal input from the signal processor 6 and outputs the video and audio signals separately.

The encoder 11 encodes the video signal output from the decoder 10 into a single video signal, converts the video signal into a composite video signal, and outputs the video signal to an image display device (not shown) such as a television receiver.

At this time, the encoding unit 11 encodes by a National Television System Committee (NTSC), Phase Alternating by Line (PAL) or Sequentiel couleur a memoire (SECAM) method, and outputs a composite video signal according to the method adopted in each country. do.

The audio amplifier 12 amplifies the audio signal output from the decoder 10 and outputs the audio signal to a video display device or a speaker connected to the outside.

When the user mounts the optical disc 2 on the deck (not shown) in order to use the optical disc player having the above-described configuration, the disc motor 1 is driven to rotate the optical disc 2 while the optical pickup 4 ), Data recorded on the upper surface of the optical disc 2 starts to be reproduced.

In order to play the optical disc 2, the lead-in area is first read by the optical pickup 4, and the type of the optical disc, the number and size of programs stored on the optical disc, the address of each program, i.e. the position on the optical disc, the start of each track General information of the disc, such as time and total reproduction time of the optical disc, is applied to the control unit 7 and recorded.

Thereafter, corresponding control signals are output in accordance with various key inputs of the user to perform the overall reproducing operation of the optical disc 2.

However, when using the conventional optical disc player as described above, since the total play time of the optical disc, the play time of each track, etc. are simply displayed, the information on the recorded song cannot be displayed. In order to find out, the user has to look at the contents printed on the upper surface of the optical disk or the inconvenience of having to look at the contents written on the case containing the optical disk.

Accordingly, it is an object of the present invention to provide a music input / output device and an input / output method of an optical disc reproducing apparatus that can display a character input when playing a corresponding song after briefly inputting a song recorded on an optical disc such as a DVD.

A control unit which outputs a control signal and outputs a control signal to find and display a stored song when the optical disc is played, and stores a song input through a key input unit under control of the controller and outputs a song input when playing the corresponding song. EEPROM and a display unit for displaying the songs recorded in the EEPROM under the control of the control unit during the playback of the optical disk, and if the optical disk mounted on the deck is not recorded in the EEPROM Inputted and recorded in the EEPROM together with the data of the lead-in area of the optical disc. Songs of music played back according to the playback signal by the user are displayed on the display unit, and if an optical disc mounted on the deck is pre-recorded in the EEPROM, the music played in accordance with the playback signal by the user is not required without a song input process. The music piece is displayed through the display unit.

Hereinafter, a music input / output device and an input / output method of an optical disc player according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a block diagram schematically showing the configuration of a music input / output device of an optical disc player according to the present invention. The disc motor 100, the optical disc 101, the objective lens 102, the optical pickup 103, and the RF amplifier unit are shown in FIG. The signal processor 105, the motor driver 107, the motor 108, the decoder 109, the encoder 110, and the audio amplifier 111 are the same as those described in FIG. Detailed descriptions thereof will be omitted.

The control unit 106 controls the overall reproducing operation of the optical disc according to the user's key input, and controls the EEPROM 113 to store the songs contained in the optical disc input by the user through the key input unit 112 described later. Outputs a control signal to search for a piece of music stored in the EEPROM 113 and display it on the display unit 114 when the optical disc is reproduced.

The key input unit 112 inputs music pieces recorded on the optical disc currently mounted on the deck by the user.

When selecting and inputting a piece of music, the characters appearing on the display unit 114 to be described later are selected one by one, and input by using keys provided in a remote controller (not shown).

In this case, the song title input by the user may input Korean or English, and input the entire song name or information summarized by the user.

The EEPROM (Electrically Erasable and Programmable Read Only Memory) 113 stores a piece of music input through the key input unit 112 under the control of the controller 106 and outputs a piece of music input when the song is played.

When music pieces are stored in the EEPROM 113, the data recorded in the lead-in area of each optical disc mounted on the deck are stored together, and the stored contents are retained as long as they are not erased by the user.

That is, even if the deck is opened to replace the optical disc mounted on the deck, the stored information is not lost, and when the optical disc of the previously stored contents is played again, information such as music pieces does not need to be input again.

The display unit 114 displays a piece of music output from the EEPROM 113 under the control of the control unit 106 when the piece of music is recorded.

Next, the operation of the music input / output device of the optical disk player according to the present invention configured as described above will be described in detail with reference to FIG.

Figure 3 is a flow chart showing in detail the flow of the music input and output process of the optical disk player according to the present invention.

When the user intends to use the optical disc player, it is first determined whether the optical disc is mounted on the deck (S100).

If it is determined that the optical disc is mounted on the deck, the data of the lead-in area of the optical disc is read through the optical pickup 103 (S101).

After that, it is judged whether or not data of the read-in area to be read is recorded in the EEPROM 113 (S102).

If the determination result is not recorded in the EEPROM 113, it is now determined whether the music piece selection key is input by the user (S103).

When the song selection key is input by the user, the song title for the corresponding song input by the user is input (S104).

The music pieces thus input are recorded together with the data of the lead-in area in the EEPROM 113 under the control of the controller 106 (S105).

However, when the music piece selection key is not input by the user as a result of the determination in step S103 described above, various operations of the optical disc player according to the user's key input are performed (S106).

After the input of the music piece input of the optical disc by the above-described method, it is determined whether the optical disc is reproduced by the user's selection (S107).

As a result of the determination, when the play key signal is input by the user, the music piece input by the user of the music being played under the control of the controller 106 is displayed on the display 114 (S108).

On the other hand, when the optical disk in which the data of the lead-in area of the optical disk read through the optical pickup 103 in the above-described step S102 has already been recorded in the EEPROM 113 is mounted, there is no need of the music piece input process as described above. The above-described step (S108) is performed.

As described above, according to the music input / output device and the input / output method of the optical disk player according to the present invention, the user can display the music input input by the user together with the total playback time of the optical disk, the playback time of each track, and the like. There is a convenience that can immediately recognize what kind of music is currently playing without having to look for each one.
