Abstract

An optical disc player discriminates an attribution of tracks recorded onto a disc inserted in the player, and normally reproduces 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, the optical disc player discriminates a kind of an inserted disc as an audio file disc, an MP3 file disc, or a 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 audio data, the method comprising the steps of:

(a) reading an attribute information associated with audio file and discriminating a type of audio file using the attribute information, wherein the attribute information includes an extension of the audio file; and

(b) establishing a reproducing mode in response to the type of audio file as a result of the step (b), and reproducing the audio file according to the reproducing mode.

2. The method of claim 1, wherein the audio file includes one of first type audio discriminated by the extension of “

wav” and

second type audio discriminated by the extension of “

mp3”

, according to each attribute information.

3. The method of claim 2, wherein the step (b) comprises steps of:

(b1) checking a current reproducing mode; and

(b2) changing the current reproducing mode into another reproducing mode based on the attribute information, if the audio file can not be reproduced according to the current reproducing mode.

4. The method of claim 1, wherein the step (b) comprises steps of:

(b1) identifying a current reproducing mode prior to reproducing the audio file discriminated by the attribute information; and

(b2) determining whether to maintain the current reproducing mode according to the attribute of the audio file.

5. The method of claim 4, further comprising the step of (b3) changing the current reproducing mode into another reproducing mode to reproduce the audio file if the current reproducing mode cannot reproduce the audio file according to the attribute information.

6. The method of claim 1, wherein if an extension of the audio file is “

mp3”

as a result of step (a), further comprising the steps of;

(c1) obtaining a header information of the audio file; and

(c2) deciding whether the audio file constructs normal MP3 audio data or not, based on the obtained header information.

7. The method of claim 6, further comprising the step of (c3) discriminating the audio file as normal MP3 audio data, if the audio file constructs the normal MP3 audio data as a result of step (c2).

8. The method of claim 6, further comprising the step of (c3) discriminating the audio file as text data, if audio file does not construct the normal MP3 audio data as a result of step (c2).

9. The method of claim 1, further comprising steps of (c) displaying information associated with the reproduced audio file on a displaying section.

10. The method of claim 9, wherein the information is at least one of a file number, a file name, an elapsed time, and a remaining time of the reproduced audio file.

11. The method of claim 10, wherein the information is associated with MP3 audio file if the attribute information indicates the extension of “

mp3”

.

12. The method of claim 1, wherein the step (b) reproduces MP3 audio file if the attribute information includes the extension of “

mp3”

.

13. An apparatus for audio data, comprising:

a controller for obtaining attribute information associated with an audio file, discriminating an attribute of an audio file based on the attribute information, and outputting a control signal to decode an audio file according to the attribute information, wherein the attribute information includes an extension of an audio file; and

a processor for decoding a first audio file or a second audio file in response to the control signal from the controller, wherein the first audio file is discriminated by the extension of “

mp3” and

the second type audio is discriminated by other extension, according to each attribute information.

14. The apparatus of claim 13, wherein the controller outputs a control signal to decode MP3 audio file if the attribute information indicates the extension of “

mp3”

.

15. The apparatus of claim 13, wherein the controller outputs a control signal such that the processor decodes the first audio file if the attribute information indicates the extension of “

mp3”

, the first audio file being an MP3 audio file, while the processor decodes the second audio file if the attribute information indicates another extension different than “

mp3”

.

16. The apparatus of claim 15, wherein another extension includes “

wav”

.

17. The apparatus of claim 13, wherein the controller further determines a current decoding mode to decode the discriminated audio file, wherein the controller outputs a control signal to change the current decoding mode into an alternative reproducing mode if the current reproducing mode cannot decode the discriminated audio file.

18. The apparatus of claim 13, further comprising:

a digital to analog converter for converting the MP3 audio file of the first audio file or another audio file decoded from the processor into an analog signal; and

an output section for outputting the analog signal.

19. The apparatus of claim 18, further comprising:

a display unit to display at least one of a file name,

an elapsed time, and

a remaining time for at least the MP3 audio file.

20. A method of reproducing audio data, the method comprising the steps of:

(a) identifying type of audio data based on an attribute information, wherein the attribute information includes extension information indicating an extension of audio data; and

(b) determining whether to reproduce the audio data as a result of step (a).

21. The method of claim 20, wherein the step (b) comprises the steps of:

(b1) identifying a current reproducing mode to reproduce the identified audio data; and

(b2) determining whether to change the current reproducing mode in response to the identified audio data.

22. The method of claim 21, further comprising the step of (b3) interrupting an operation for reproducing the audio data if the type of the audio data does not correspond to the current reproducing mode.

23. The method of claim 20, wherein the step (b) reproduces the audio data normally if an established decoding mode corresponds to the attribute information while the step (b) does not reproduce the audio file if the established decoding mode does not correspond to the attribute information.

24. The method of claim 20, wherein the audio data is at least one of first type audio discriminated by the extension of “

mp3”

, the first type audio being MP3 audio data, and second type audio discriminated by the extension of “

wav”

, according to each attribute information.

26. The method of claim 24, wherein the audio data is at least one of first type audio discriminated by the extension of “

mp3”

, the first type audio being MP3 audio data, and second type audio discriminated by another extension, according to each attribute information.

27. The method of claim 26, wherein another extension includes “

wav”

.

25. A method of reproducing audio data, the method comprising the steps of:

(a) identifying a type of audio data based on an attribute information, wherein the attribute information includes an extension of audio data; and

(b) controlling a reproduction of the identified audio data as a result of step (a).

28. A method of reproducing audio data, the method comprising the steps of:

(a) identifying type of audio data based on an attribute information, wherein the attribute information includes an extension of audio data; and

(b) determining a decoding mode to decode the identified audio data in response to the attribute information.

29. The method of claim 28, wherein the audio data is at least one of first type audio discriminated by the extension of “

mp3”

, the first type audio being MP3 audio data, and second type audio discriminated by other extension, according to each attribute information.

30. The method of claim 29, wherein other extension includes “

wav”

.

31. A method of reproducing audio data, the method comprising the steps of:
