How to Display Playback CD Information on Video CD Player

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a device that applies a moving picture expert group (MPEG) coding scheme such as a video compact disk player or a video CD auto-changer. The present invention relates to a method of displaying playback CD information of a video CD player, which stores information about a video CD in a memory and displays the information on a monitor when necessary.

1 is a block diagram of a general video CD player.

As shown, a program storage unit (1) for storing a program to perform the playback operation of the video CD player; A central processing unit (2) for performing overall control to operate a video CD player according to a program stored in the program storage unit (1); A compact disk kit (3) for reading data from the video CD under the control of the central processing unit (2); An MPEG decoder 5 for decoding data transmitted from the CD kit 3 in an MPEG manner; A TV (6) for displaying a video signal output from the MPEG decoder (5); The speaker 7 is configured to output an audio signal output from the MPEG decoder 5 to the outside.

The operation of the video CD player configured as described above is as follows.

First, when a playback key is input from the outside, the central processing unit 2 controls the video CD to read data from the video CD through the CD kit 3. When the data is read from the video CD, the CD kit 3 transfers the read data to the MPEG decoder 5, and the MPEG decoder 5 decodes the data into MPEG and decodes the data into a video signal and an audio signal. The output will be sorted.

Then, the TV 6 displays the video signal output from the MPEG decoder 5, and the speaker 7 outputs the audio signal transmitted from the MPEG decoder 5.

Thus, the conventional video CD player has a disadvantage in that duplicate purchase of a disc may occur because it does not have the ability to store information about the played video CD. In particular, when storing and loading dozens of video CDs in a video CD auto changer, it is inconvenient not to know which video CD is present without opening the slot directly.

Disclosure of the Invention An object of the present invention is to solve the conventional problems as described above. In particular, the playback CD information of a video CD player that can easily know information about the disc by recording the information on the reproduced disc and displaying the information if necessary. To provide a display method.

In order to achieve the above object, the present invention (method) is,

A CD information input step of reading a CD title (title name) together with Table Of Content (TOC) information from a video compact disk; A playback status display step of displaying whether or not playback is performed by comparing the inputted CD information with previously stored CD information stored in a memory; When the play key is input, the video CD is played, and the CD information storage step of storing the information of the played video CD is characterized in that the method configuration.

Hereinafter, the configuration and operation of an embodiment according to the technical spirit of the present invention "method of displaying playback CD information of a video CD player" will be described in detail with reference to the accompanying drawings.

<Example>

First, as shown in FIG. 2, a video CD player to which the present invention is applied comprises: a program storage unit 1 storing a program for storing and displaying information on a played video CD; Performs overall control to operate the video CD player according to the program stored in the program storage unit 1, reads the information on the played video CD from the memory 8, and stores the information about the first played video CD. A central processing unit (2) for recording in (8); A compact disk kit (3) for reading data from the video CD under the control of the central processing unit (2); A dynamic RAM 4 for temporarily storing information on the video CD being played; A memory (8) for storing information on the video CD read from the CD kit (3) and drawing out information on the played video CD to the central processing unit (2); An MPEG decoder (5) which analyzes the data read from the CD kit (3), provides information to the central processing unit (2), and decodes the data in an MPEG manner to output a video signal and an audio signal; A TV (6) for displaying a video signal output from the MPEG decoder (5); The speaker 7 is configured to output an audio signal transmitted from the MPEG decoder 5 to the outside.

The playback CD information display method of the video CD player performed in the video CD player configured as described above includes a CD information input step of reading a CD title together with TOC (Table Of Content) information from the video CD as shown in FIG. ST11-ST15); A playback status display step (ST16-ST18) which displays whether or not playback is performed by comparing the inputted CD information with the CD information stored in the memory 8; When a play key is inputted, a CD information storage step (ST19-ST22) of playing a corresponding video CD and storing information of the played video CD is performed.

In the above-described CD information input step (ST11-ST15), if the version of the video CD reading the TOC information is 2.0, the step of reading the CD title at the corresponding position (ST11-ST13), and the video CD reading the TOC information If the version is not 2.0, a step of receiving a CD title from the outside (ST14) and a step of temporarily storing the obtained CD title in the dynamic RAM 4 (ST15).

In addition, the storage of the CD information (ST19-ST22) includes the step of starting the playback of the video CD when the play key is input (ST19-ST20), and the information of the disc in the memory 8 when the playback of the corresponding disc is completed. It is made up of steps ST21-ST22.

A method of displaying playback CD information of a video CD player according to the present invention will be described as follows.

First, when a power key of a video CD player is turned on and a video CD to be played is inserted, the CD kit 3 is controlled from the video CD under the control of the central processing unit 2. Of Content) information is read and the central processing unit 2 is informed whether the version of the video CD for reading data is 1.1 or 2.0 (ST11). At this time, if the version of the video CD that reads data is 2.0, information about 2.0 in the data area is read and transmitted to the MPEG decoder 5. Then MPEG decoder 5 analyzes the video CD title (title name) included in this information and transmits it to the central processing unit 2 (ST12-ST13). The processing device 2 temporarily stores information on the CD in the dynamic RAM 4 (ST15).

If the version of the video CD driven above is 1.1, since the title of the video CD is not recorded in the video CD 1.1, information about the video CD is received from the outside and temporarily stored in the dynamic RAM 4 (ST14-). ST15).

When the information on the video CD being driven in the dynamic RAM 4 is stored, the central processing unit 2 compares the information on the video CD that was previously played back stored in the memory 8 (ST16). It is determined whether the video CD being driven is the video CD which has been played before (ST17). As a result, if the disc has been played before, it displays the played video CD on the monitor and informs the user (ST18).

Then, when a play key is input, the CD kit 3 drives the video CD under the control of the central processing unit 2 to start playback (ST19-ST20). At this time, when the video CD is played to the end and the playback operation is completed, the CPU 2 stores the information about the video CD temporarily stored in the dynamic RAM 4 in the memory 8 (ST21-ST22).

In addition, when the information on the video CD that has been played back is manipulated from the outside to be displayed, the central processing unit 2 displays the information on the played video CD stored in the memory 8 on the monitor. The central processing unit 2 allows the user to play the same video CD again.

As described above, the present invention "method of displaying the playback CD information of the video CD player", in particular, stores the information on the playback video CD in the memory, and when the corresponding key is operated by the user to display the video CD It is effective to make it easy to know information about.
