Abstract

The present invention relates to a stationary song song title display device that displays the name of a song recorded on a disc on a monitor during a pause mode in a disk-based video player, thereby relieving the inconvenience of having to take out a disc in order to know the name of a song on the disc. will be.

To this end, the present invention includes a RAM 700 that reads the song song name data of the lead-in area that is read during the initial playback after the disk 100 is mounted, and reads the stored data during the stop mode.

The control unit 600 controls the memory and the read operation of the RAM 700, and applies the song song name data read in the lead-in area of the disk 100 to the RAM 700 while being read from the RAM 700 By providing a signal demodulation unit 300 for mixing the data with the blue back screen signal, and outputting the name of the song song recorded on the disk in the still mode.

The present invention provides a disc-recorded video signal reproducing apparatus (LDP.CD-FMV) in which a song song name display device is displayed on a monitor to display a song song name recorded on a disc in a stop mode when a disc containing a song is played. In particular, when playing a song disc containing a variety of songs, you can find the song you want quickly and accurately.

When watching a video signal recorded on a disc using a disc-using device and listening to a song (music), that is, during playback, the way to know the name of the song on the disc is to read the song name written on the storage case for storing the disc or It was possible to take it out and read the song name on the front of the disc.

Otherwise, starting with the first song on the disc, finding and listening to the desired song was a common usage.

As such, it is inconvenient to know the name of the song recorded on the disc during the playback of the disc. The present invention makes it easy to display the song song name of the disc on the monitor when the disc stops during playback of the disc. It is to be recognized.

The present invention, which aims to display the name of the song recorded on the disc on the monitor during the stop mode, includes memory means for memorizing the song name data recorded in the read-in area of the disc;

Control means for controlling the operation of the memory means and controlling the operation of reading the memorized data during the stop mode;

And signal demodulation means for displaying the title data read out from the memory means on a monitor.

This invention is described in detail based on the accompanying drawings as follows.

Information contained in the disk 100 mounted on the turntable and rotated is detected by the pickup device of the optical system 200.

The data detected by the optical system 200 is applied to the signal demodulator 300 and demodulated into video and audio signals, and then output to the monitor and the speaker of the rear stage.

The turntable on which the disk 100 is mounted is rotated by the rotation of the motor, which is the rotary mechanism 500, and the operation of the rotary mechanism 500 is controlled by the surge tool 400.

The search tool 400 recognizes a micom command of the manipulation control unit 600 that recognizes a key input and applies a control signal to the rotating mechanism 500.

Such a configuration of the disk 100, the optical system 200, the signal demodulation unit 300, the servo gear 400, the rotation mechanism 500, the microcomputer 600 is a general technical content of the existing disk using apparatus.

The present invention includes a RAM 700 for recording song title data in the lead-in area of the disc 100 and storing and reading song title data separated from the signal demodulator 300.

The memory and read operation of the RAM 700 is configured to be controlled by the operation control unit 600.

Here, the signal demodulation unit 300 outputs a blue back screen processing signal to the monitor when the stop mode is not a song playback operation, and in the present invention, the RAM back to the blue back screen processing signal described above during the stop mode. By mixing the read song song data to display the song song name on the blue back screen during still mode.

Hereinafter, the present invention will be described in detail.

The microcomputer of the operation control unit 600 recognizes key data of a key input unit (not shown) to control the operation of the set. When a reproduction key is input, the microcomputer issues a reproduction command to the servo mechanism 400.

The servo mechanism 400 sends a rotation control signal to the motor, which is the rotating mechanism 500, to rotate the motor when there is a regeneration command from the operation controller 600.

The servo mechanism 400 stops the motor by sending a stop control signal to the rotary mechanism 500 when a stop command is received from the operation controller 600.

When the motor, which is the rotating mechanism 500, rotates, the disk 100 mounted on the turntable rotates.

When the disk 100 rotates, the optical system 200 sends light to the disk 100 to detect the light reflected from the disk 100 and changes the current value to a current value to convert the data contained in the disk 100 into the optical system 200. Will be detected.

The signal detected by the optical system 200 is applied to the signal demodulator 300 to be demodulated into an image and an audio signal and then output to a monitor or a speaker at the rear end.

The above operation is a general operation for the disc-using video player.

According to the present invention, the data stored in the lead-in area of the disk 100 is stored in the RAM 700 and then read in the stop mode and displayed on the blue back screen.

That is, when the reproduction operation of the first disc 100 starts, the optical system 200 picks up a lead-in area set separately at the innermost side of the disc 100.

At this time, all information (song name, order, actual playing time, position recorded on the disc, etc.) of the disc 100 is stored in the lead-in area, and the information about the disc 100 is read before the disc 100 is played. The first lead-in area is read because all operations are available on the set.

Data of the lead-in area read by the optical system 200 is stored in the RAM 700 through the signal demodulator 300.

At this time, the RAM 700 memorizes the song song name of the lead-in area by the recording signal from the operation control unit 600, and the operation control unit 600 outputs the recording signal with the reproduction command at the beginning of the disc 100 playback. In 700, the song song name of the lead-in area is memorized.

When the memory operation with respect to the lead-in area is completed, the operation controller 600 blocks the write signal applied to the RAM 700.

Therefore, in the RAM 700, the song song names recorded on the disc 100 are stored before the playback of the songs recorded on the disc 100 starts.

The song song name data stored in the RAM 700 is read when one song is finished and the set is stopped.

In other words, when the song recorded on the disk 100 is finished, the operation control unit 600 sends a read signal to the RAM 700 to read data stored in the RAM 700.

Song song data read from the RAM 700 is applied to the signal demodulator 300.

In this case, the signal demodulator 300 outputs a blue back screen signal during the stop mode instead of playing a song to display the monitor screen in blue.

The present invention is to mix and output the song song name data read from the RAM 700 to the blue back screen signal output from the signal demodulation unit 300 during the stop mode

The song song name is displayed on the blue screen during the still mode.

As described above, the present invention displays the song song name of the disc on the monitor when one of the songs is finished playing on a disc-enabled video player, so that the user can simply view the name of the song on the disc currently installed. It is easy to see.

This makes it easier to find the song you are looking for and offers superior ease of use compared to existing products.
