Description

Compact Disc regenerating device and the method using an Index}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a compact disc reproducing apparatus using a list and a method thereof, wherein a disc reproducing apparatus stores a list of data in a program area of a disc in a disc start area (hereinafter referred to as a "list area"). And to a method thereof.

The data stored on the compact disc is a digital signal made up of a combination of 0's and 1's, and the music is played according to the order, and information on the start and end points of each song can be stored to select a desired song. But it was inconvenient to search from the beginning to select the required song. In particular, it is difficult to select a song to listen to the desired music by operating a compact disc player while moving, such as driving a car. Therefore, there is a demand for a technology for selecting a song to be listened to conveniently by a user within a short time.

In order to reduce the time required to search from beginning to end in order to select a compact disc, the user arbitrarily sets a time for reproducing the list portion in the program area of the disc, and only during the setting time. It is published in Korean Patent No. 10-260355 to play back the first part of the song for the list so that the user can select a list to listen to.

The registered patent No. 10-260355 does not only play for a predetermined time from the start of playing the corresponding list during partial play for the list introduction, but also introduces the time arbitrarily set by the user from the time when the reproduction output signal is detected over a certain value. The present invention relates to a method of controlling the list introduction data replay, which plays the corresponding list only and then sequentially reproduces the contents of the list for the next list.

The method for controlling list introduction data reproducing according to the prior art includes: a first step of reproducing and outputting corresponding data of an arbitrary list, a second step of detecting a time point at which the output signal becomes a predetermined reference value or more, and starting from the detected time point Including the third step of reproducing the list of the data only for a preset introduction time, the list can be introduced reliably regardless of the nature and genre of the list, thus making it easy to select the list. In addition, by allowing the user to set a variable time for a predetermined time from the predetermined value or more, an appropriate list introduction time can be set according to the type and genre of the disk owned by the user.

This prior art has the effect of shortening the time for selection by appropriately reducing the time required to play the first part of the song corresponding to the list by the set time, but the list itself in the lead-in area at the beginning of the disc. Since it is not possible to select the song that the user wants, it takes a lot of time because the user has to select all the songs in the program area one by one and play them for the set time for each song until the user finds the desired song.

The present invention has been devised to solve the above problems, and a list having data information in a program area of a compact disc is stored in the list area of the disc, so that the disc can not be selected without selecting all the songs in the program area of the disc. The present invention provides a compact disc reproducing apparatus using the list, and a method thereof, by allowing a listener to select a song to be listened to within a short time by reproducing and selecting only a list in the list area of the list.

Another object of the present invention is to display or voice output the list stored in the list area of the compact disc on the screen through the monitoring unit by the input signal of the list playback request key input unit by the user, One-touch screen to select the song you want to listen to the automatic playback of the song.
