Abstract

Disclosed an optical disc player discriminates an attribution of tracks recorded onto an inserted disc, and normally reproduce MP3 tracks recorded onto discs inserted into a plurality of disc drivers using an MP3 decoder. Also, according to a method of reproducing an optical disc player, the optical disc player discriminate a kind of an inserted disc at the optical disc player with an audio file disc, an MP3 file disc, and an general data file disc and normally performs a reproducing operation for the files or music recorded onto the inserted disc.

Claims

1. A method of reproducing a disc in an optical disc player, the method comprising the steps of:

(a1) obtaining a TOC(Table Of Content) information of an inserted disc;

(b1) obtaining an attributive information of the inserted disc file from the TOC information; and

(c1) discriminating a kind of the inserted disc using the attributive information obtained in (b1) step.

2. The method of claim 1, further comprising the step of reproducing tracks of the inserted disc by establishing a reproducing mode according to an attribution of the inserted disc after performing the discriminating step.

3. The method of claim 2, wherein the step of reproducing the track of the inserted disc by establishing the reproducing mode according to the attribution of the inserted disc, comprising the sub-steps of:

obtaining an information for the established reproducing mode at present; and

discriminating whether or not the track according to the reproducing mode established at present is recorded or not on the inserted disc with reference to the attributive information of the obtained track, and reproducing the track of the inserted disc according to the current reproducing mode if the track according to the present reproducing mode exists on the inserted disc.

4. The method of claim 3, further comprising the step of changing the current reproducing mode into the reproducing mode according to the track of the inserted disc and reproducing the track of the disc, if the track according to the reproducing mode does not exist on the inserted disc by discriminating whether the track according to the current reproducing mode is recorded or not on the inserted disc.

5. The method of claim 1, wherein the optical disc player interrupts a play operation for the inserted disc and transits a standby mode waiting for a next command from a user, if the attribution of the inserted disc does not correspond to the current reproducing mode.

6. The method of claim 1, wherein the optical disc player obtains the attributive information of the inserted disc file, the optical disc player perceives the attribution using an extension of the disc file from the TOC information obtained from the inserted disc.

7. The method of claim 6, wherein if the extension of the inserted disc is “

mp3”

, the optical disc player discriminates the disc file as an MP3 file.

8. The method of claim 6, wherein if the extension of the inserted disc is “

wav”

, the optical disc player discriminates the disc file as an audio file.

9. The method of claim 1, wherein if an extension of the disc file is “

mp3”

recorded onto the inserted disc after discriminating the kind of the inserted disc, further comprising the steps of;

obtaining a header information of the disc file;

deciding whether the disc file constructs normal MP3 streams or not by using the obtained header information; and

discriminating as a MP3 file for the disc file and as a MP3 disc for the disc, if disc file constructs the normal MP3 streams.

10. The method of claim 9, wherein the optical disc player discriminates as a text data file for the disc file, if disc file does not construct the normal MP3 streams.

11. The method of claim 1, wherein after discriminating the kind of the inserted disc, further comprising the step of classifying and numbering the tracks by each attribution using the attributive information obtained at the (b) step, respectively.

12. The method of claim 11, wherein if the tracks are MP3 tracks, the MP3 tracks are numbered according to a hierarchy order of a tree structure referring to a file information of the tree construction for a file system of the obtained MP3 tracks.

13. The method of claim 12, wherein the MP3 tracks are numbered according to the hierarchy order of the tree structure referring to the file information of the tree construction for a file system, the MP3 tracks are sequentially numbered according to a horizontal hierarchy of the tree construction.

14. The method of claim 12, wherein the MP3 tracks are numbered according to the hierarchy order of the tree structure referring to the file information of the tree construction for a file system, the MP3 tracks are sequentially numbered according to a vertical hierarchy of the tree construction.

15. The method of claim 11, wherein if the tracks are MP3 tracks, the MP3 tracks are arranged on the basis of a specific field and numbered according to the arranged order referring to information for a file system of the obtained MP3 tracks.

16. The method of claim 15, wherein the MP3 tracks are arranged on the basis of the specific field, the field selectively including MP3 tracks file name, MP3 tracks playing time, and MP3 tracks storing time.

17. The method of claim 1, further comprising the step of reproducing MP3 tracks of the disc and sequentially displaying information of the reproducing MP3 file on a displaying section of the optical disc player according to a user requirement, if the inserted disc is discriminated as the MP3 disc.

18. The method of claim 17, wherein the information of the reproducing MP3 file on the displaying section of the optical disc player according to the user requirement, are selectively displayed from a current reproducing MP3 track number, a current reproducing MP3 track name, a current reproducing MP3 track number, a current reproducing MP3 track elapsed time, and a current reproducing MP3 track remain time.

20. The optical disc player of claim 19, wherein each disc driver has the first control section, respectively.

21. The optical disc player of claim 19, wherein the second control section comprising:

a plurality of slave controllers for converting the MP3 track data recorded onto the disc inserted into the disc drivers into decodable data; and

Master controllers for controlling the decoding order for the converted signal of the plurality of slave controllers.

22. The optical disc player of claim 21, wherein the each disc driver has the slave controller, respectively.

19. An optical disc player comprising:

a plurality of disc drivers for receiving each disc;

a first control section for obtaining an attributive information of tracks of each disc inserted each disc driver and performing an overall control for the optical disc player;

a second control section for receiving an MP 3 track data from the first control section and converting the received MP3 track data into decodable data, and controlling a decoding order for the converted data;

an MP3 decoder for decoding the converted MP3 track data provided from the second control section and forwarding the decoded data to the second control section;

a digital to analog converter for converting the converted MP3 track data provided from the second control section into analog data; and

an output section for outputting the converted analog data.
