BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an in-vehicle multimedia device, and more particularly to a plurality of multimedia disks using a disk changer used in A / V (Audio / Video) and AVN (Audio / Video / Navigation). In a vehicle multimedia apparatus capable of playing, a vehicle multimedia that allows a user to designate and reserve songs in the plurality of multimedia disks (hereinafter, referred to as 'disks') and plays back the songs that are reserved by the user in a specified order. A disk content designation reservation method for a device.

In-vehicle multimedia device performs a function of playing music and video from the multimedia that the user wants to play in the vehicle, and outputs it through a speaker and a monitor. In general, contents storage means played in a vehicle multimedia apparatus includes magnetic tape, audio compact disk (ACD), video compact disk (VCD), and digital versatile disk (DVD).

Among them, ACD, VCD, DVD, etc. are mainly used because they can store a large amount of content as well as provide high-quality and high-definition content in a car multimedia device.

However, one disc cannot contain everyone's favorite content, for example, even if the content on the disc is the song of a favorite singer, the song that you listen to will be part of the stored content. Of the many contents contained in one disc, the song, music, and video that one wants to listen to are one part.

And at this moment, you can't keep listening to any one of the many discs that are constantly being made and sold. You may want to listen to the serene and lyrical music even when you are enjoying the cheerful and fast music of tempo, so to keep listening to the contents you want, you can continue to play the discs storing the contents whenever the contents are finished. There is inconvenience that needs to be changed.

In recent years, a disk changer is often used as a device to reduce the inconvenience of replacing such a multimedia disk. The disc changer can insert a large number of discs at a time, so that a user can save the trouble of replacing a disc with a new disc even if a single disc is finished playing.

However, the disc changer makes it easy to select another disc on one disc, but you can selectively listen to track 3 on the first disc, track 4 on the second disc, and track 1 on the fourth disc. There is no. Therefore, many people collect their favorite songs and store them on a single disk, and use MP3 which is easy to store, delete and move contents.

In particular, in a vehicle multimedia device, the special situation of driving does not allow one moment of vigilance, so even if the disc changer is used, the disc in the disc changer must be searched and the corresponding content is found in the replaced disc. The difficulty is still there.

Therefore, in a vehicle multimedia device that uses a disk changer for the driver's safe driving with efficient utilization of the vehicle multimedia device, each driver selects contents to be listened to from a plurality of disks in the disk changer, and replaces a separate disk or There is a great need for a technology that can listen to only selected content in succession without input of a control signal.

Accordingly, an object of the present invention for solving the above problems is to specify and reserve the desired content from the plurality of disks mounted on the disk changer used in the vehicle multimedia apparatus first, and then to reserve the content in a reserved order without any further operation during playback. A disk content designation reservation method for a multimedia device for a vehicle which enables playback of specified content is provided.

In order to achieve the above object, the present invention provides a disk content designation reservation method for a multimedia device for a vehicle having a disk changer.

Displaying the function buttons for playing the multimedia device, detecting the pressing of the function buttons to generate a corresponding input signal, and the disk content designation button and reservation button on the touch screen to display the disk insertion state of the disk changer More equipped,

In response to the pressing of the reservation button, the user switches to a disk content designation reservation screen that can designate one of contents stored in each of the disks inserted into the disk changer, and one for each disk in response to the pressing of the designation button. Designating each of the contents and reserve the order, and when the reservation of all the disks inserted into the disk changer is complete, the contents of the disk content designation reservation method of the multimedia device for the vehicle, characterized in that for playing the contents of the disk in the reserved order. to provide.

In addition, in the disk content designation reservation method of a vehicle multimedia apparatus according to the present invention, the disk insertion state of the disk changer may be displayed by distinguishing between the currently selected disk, a disk which is not selected but inserted and no disk. It is desirable to be able to clearly inform the status of the disk changer.

In addition, in order to achieve the above object, the present invention displays a function button for playing a multimedia device, detects the pressing of the function button to generate a corresponding input signal, and has a disk changer, In the disk content designation reservation method for a multimedia device for a vehicle further comprising a disk content designation button and a reservation button on a touch screen displaying a disk insertion state,

If there is an input signal for executing the disk changer, displaying the disk changer screen on a display device of the multimedia apparatus;

Checking the number of discs in the disc changer and displaying an insertion state;

Activating the designation button and the reservation button if the number of disks of the disk changer is two or more;

Switching to a disc content designation reservation screen when there is an input signal from the reservation button, displaying a current disc content designation reservation state, and waiting for a current playback track reservation;

If there is an input signal from the designated button, reserving a current playback track and displaying the reserved playback track corresponding to the disc;

When the reservation for the last disk is terminated, playing the contents of the disk in the order of the reservation; provides a disk content designation reservation method for a multimedia device for a vehicle.

In the method for displaying multimedia information of a vehicle multimedia apparatus according to the present invention, if the number of disks of the disk changer is one or less, deactivating the designation button and the reservation button.

In the disk content designation reservation method for a multimedia device for a vehicle according to the present invention, the step of displaying a disk insertion state of the disk changer may be performed by distinguishing between a currently selected disk, a disk which is not selected but is inserted, and no disk. By doing so, it is desirable to be able to clearly inform the user of the status of the disk changer.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. First of all, in adding reference numerals to the components of each drawing, it should be noted that the same components have the same reference numerals as much as possible even if they are displayed on different drawings. Detailed descriptions of well-known functions and configurations that are determined to unnecessarily obscure the subject matter of the present invention will be omitted.
