Abstract

A method of reproducing an audio file includes: identifying a type of audio data in the audio file based on an extension information of the audio file separated from but associated with the audio data of the audio file; and determining whether the audio file is reproducible by checking whether a part of the audio file constructs a specific format stream corresponding to the identified audio type.

Claims

1. A method of reproducing an audio file, comprising:

identifying a type of audio data in the audio file based on an extension information of the audio file separated from but associated with the audio data of the audio file; and

determining whether the audio file is reproducible by checking whether a part of the audio file constructs a specific format stream corresponding to the identified audio type.

2. The method of claim 1, wherein the determining step is performed under a reproducing mode established based on the type of the audio data.

3. The method of claim 2, further comprising automatically changing the established reproducing mode to another reproducing mode if the audio file is not reproducible under the established reproducing mode.

4. The method of claim 2, further comprising skipping the audio file if the audio file is not reproducible under the established reproducing mode.

5. The method of claim 2, further comprising controlling for continuously reproducing audio files reproducible under the established reproducing mode.

6. The method of claim 2, further comprising controlling for selectively reproducing audio files reproducible under the established reproducing mode.

7. The method of claim 1, further comprising displaying information including at least title information of a current reproduced audio file.

8. An apparatus for reproducing an audio file, comprising:

a file type identifier for identifying a type of audio data in the audio file based on an extension information of the audio file separated from but associated with the audio data of the audio file; and

a checking controller for determining whether the audio file is reproducible by checking whether a part of the audio file constructs a specific format stream corresponding to the identified audio type.

9. The apparatus of claim 8, further comprising a mode establishing controller for establishing a reproducing mode based on the type of the audio data, wherein the controller determines whether the audio file is reproducible by checking whether a part of the audio file constructs a specific format stream corresponding to the identified audio type under the reproducing mode.

10. The apparatus of claim 9, wherein the mode establishing controller automatically changes the established reproducing mode to another reproducing mode if the audio file is not reproducible under the established reproducing mode.

11. The apparatus of claim 9, wherein the apparatus skips the audio file if the audio file is not reproducible under the established reproducing mode.

12. The apparatus of claim 9, further comprising a reproducing controller for controlling continuously reproducing audio files reproducible under the established reproducing mode.

13. The apparatus of claim 9, further comprising a reproducing controller for controlling selectively reproducing audio files reproducible under the established reproducing mode.

14. The apparatus of claim 8, further comprising a display for displaying information including at least title information of a current reproduced audio file.
