KR100273332B1 - Method of replaying compact disk player memory - Google Patents

Abstract

PURPOSE: A method of replaying a compact disk player memory is provided to immediately store a song selected by a user in a specific memory by adding a memory function to a compact disk player, so that the user listens to the song by reproducing the song after the replay. CONSTITUTION: A micro processor converts a compact disk player into the second program mode while replaying an optical disk. The micro processor checks whether a specific memory key is inputted by a user. If so, the micro processor stores a presently-reproduced compact disk number and a song number in a memory. If the user requests to reproduce a song, the micro processor automatically reproduces stored songs in order.

How to Play Compact Disc Player Memory

1 is a block diagram of a general compact disc player circuit.

2 is an operation flowchart according to the method for reproducing a compact disc player memory of the present invention.

* Explanation of symbols for main parts of the drawings

The present invention relates to a method of playing a compact disc player, and more particularly, to a memory of a compact disc player, in which a memory function is added to a compact disc player so that a song in play can be memorized and later played back to repeatedly listen to the memorized song. It relates to a regeneration method.

A conventional compact disc player generally used has an optical unit 1 for reading data from a compact disc and an amplifier for amplifying a signal input from the optical unit 1, as shown in FIG. (2), a digital signal processor (3) for processing the signal input from the RF amplifier (2), and a key signal from the key input unit (8), and the entire digital signal processor (3) and the like. A microprocessor 5 for outputting a control signal for controlling operation, a servo signal processor 4 for receiving a control signal from the microprocessor 5 and outputting a servo control signal, and the digital signal processor 3; The D / A converter 6 converts the digital signal input from the analog signal into an analog signal and outputs the signal, and the audio is received from the D / A converter 6 and the audio is received. Audio section 7 for outputting signals It is.

When a compact disc player wants to listen to only the desired songs from the compact discs and records them using a cassette tape recorder, the desired functions are selected and programmed using the program function.

That is, after checking the songs of the compact disc, selecting the desired songs and entering the program mode, input the desired song number or disc number (for a multi-changer compact disc player) to the microprocessor 5 through the key input unit 8. Program it.

Also, when listening to music on a compact disc player, when a song of your choice is played back, the number or title of the song is memorized and programmed.

However, such a conventional compact disc programming method has difficulty in selecting all the songs that are suitable for taste when selecting unfamiliar songs among the songs contained in the compact disc by using the program function, and when a song that matches the taste is found during playback. When you want to listen to the program again later, you have to look up the title of the song or memorize the number of the song so that you can program it later. When I was doing it was difficult to put down the title or number of the song.

Therefore, in view of the problems of the conventional method, the present invention provides a disc number and a corresponding disc number which are currently reproduced so that the corresponding music part can be recognized by a specific memory key input when music to be heard later is found during compact disc playback. Invented a compact disc player memory reproducing method in which the song number is stored in a memory and can be reproduced and listened only to the tunes according to the stored tastes by a simple operation without reprogramming at a later time. When described in detail as follows.

When playing a compact disc with a compact disc player, find a song of your choice and memorize it. If you want to listen to it again later, turn on the compact disc player and play it. Then switch the compact disc player to the second program mode and press the memory key.

When the memory key is pressed, the microprocessor memorizes the disc number currently playing (in the case of a multi-changing compact disc player) and the song number by the input signal of the memory key. At this time, the compact disc player may continuously play back the music, and when it is desired to select and memorize the music again, the compact disc player may repeatedly repeat the process and memorize the music.

When the playback of the compact disc is finished or a song to be memorized is to be played, stop the compact disc player, switch to the second program mode, and press the play key to play the compact disc. At this time, the compact disc player selects and plays only the songs stored in the memory.

Using this method of the present invention, when a music that matches the taste is found during playback, it is immediately memorized by a specific memory key input, and when the playback is completed, it is possible to play and listen to the music according to taste with a simple operation.
