The apparatus of reproducing a subtitle used in a DVD player comprises a subtitle information processing section for receiving and storing a subtitle of a language wanted by a user, and reproducing the subtitle information of the language wanted by the user on a screen.

Claims

1. A method of reproducing subtitle information in a DVD player, the method comprising the steps of:

displaying a set menu of the subtitle information;

selecting the subtitle information of a language wanted by a user;

if the subtitle information of the language wanted is not provided, receiving the subtitle information of the language wanted from a subtitle information storing section;

selecting the subtitle information of the language wanted among the subtitle information received by the subtitle information storing section; and

reproducing a picture and the subtitle information of the language selected by the user.

2. The method as claimed in claim 1, wherein the step of receiving the subtitle information comprises the steps of:

receiving the subtitle information from the subtitle information receiving section by use of a floppy disk, and storing the subtitle information in the subtitle information storing section;

receiving the subtitle information by connecting the subtitle information receiving with a network such as Internet, and storing the subtitle information in the subtitle information storing section; and

receiving the subtitle information from the subtitle information receiving section via a terminal such as a PDA, and storing the subtitle information in the subtitle information storing section.

3. The method as claimed in claim 1, wherein the step of reproducing the picture and the subtitle information comprises the steps of:

when operation of the DVD player starts, receiving an operation timing signal from an A/V signal detecting and extracting section respectively extracting an audio signal and a video signal from the received signal; and

reproducing the subtitle information corresponding to the operation timing signal of the audio signal through the subtitle information reproducing section to synchronize the subtitle information with the picture.

4. The method as claimed in claim 1, wherein the subtitle information includes subtitle head information having a title of the DVD title, a subtitle language, a font name for reproducing the subtitle, a font size, a font color and so forth, and a subtitle text information having actual subtitles having a frame number of the picture to be displayed and lines information when the picture corresponding to the frame number is displayed.

5. An apparatus of reproducing a subtitle used in a DVD player including a DVD reproducing section for driving a DVD title, an A/V signal detecting and separating section for reading audio and video signals stored in the DVD title and separating the audio signal and the video signal from the detected A/V signal, an audio signal decoding section for decoding the separated audio stream to output it to a loudspeaker, and a video signal decoding section for decoding the separated video stream to output it on a screen of a display, the apparatus comprising:

a subtitle information processing section for receiving and storing a subtitle of a language wanted by a user, and reproducing the subtitle information of the language wanted by the user on a screen.

6. The apparatus as claimed in claim 5, wherein the displayer comprises a monitor connected to a TV, a terminal of a computer, and so forth.

7. The apparatus as claimed in claim 5, wherein the subtitle information processing section includes

a subtitle information receiving section for receiving the subtitle information of the language wanted by the user, in addition to the subtitle information of a language provided the DVD title;

a subtitle information storing section for storing the subtitle information inputted from the subtitle information receiving section; and

a subtitle information reproducing section for reproducing the subtitle information stored in the subtitle information storing section.

8. The apparatus as claimed in claim 6, wherein the subtitle information receiving section includes

a floppy disk capable of receiving the subtitle information of the language wanted by the user, in addition to the subtitle information of a language provided the DVD title;

a network connecting section for receiving the subtitle information from a subtitle information providing server via Internet or receiving the subtitle information from a computer of the user; and

an infrared ray receiving section for receiving the subtitle information from a portable information terminal such as PDA.

9. The apparatus as claimed in claim 6, wherein the subtitle information storing section includes a floppy disk, a hard disk, a flash memory and so forth to store and provide the subtitle information.

10. The apparatus as claimed in claim 6, wherein the subtitle information reproducing section includes a video mixing section for erasing the subtitle information stored in the DVD title to synchronize the subtitle information selected by the user with the picture during operation of the DVD player, and superposing or mixing the subtitle information with a video signal inputted from the video signal decoding section.
