Abstract

A method of reproducing an audio file includes: determining whether the audio file is reproducible by checking whether a part of the audio file constructs a specific format stream corresponding to a predetermined audio type; and controlling for selectively reproducing only audio files reproducible based on a result of the determining step.

Claims

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

determining whether the audio file is reproducible by checking whether a part of the audio file constructs a specific format stream corresponding to a predetermined audio type, the part of the audio file being separated from but associated with audio data of the audio file; and

controlling reproduction to selectively reproduce only audio files reproducible based on a result of the determining step.

2. The method of claim 1, wherein the determining step is performed based on an extension information of the audio file separated from but associated with the audio data of the audio file.

3. The method of claim 1, wherein the controlling step is performed under a reproducing mode established based on a result of the determining step.

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

5. The method of claim 3, further comprising skipping the audio file if the audio file is not reproducible under the established reproducing mode.

6. The method of claim 3, further comprising controlling to continuously reproduce 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 checking controller configured to determine whether the audio file is reproducible by checking whether a part of the audio file constructs a specific format stream corresponding to a predetermined audio type, the part of the audio file being separated from but associated with audio data of the audio file; and

a reproducing controller configured to control reproduction to selectively reproduce only audio files reproducible based on a result of the determining step.

9. The apparatus of claim 8, further comprising a reader configured to read an extension information of the audio file separated from but associated with the audio data of the audio file, wherein the checking controller performs based the extension information.

10. The apparatus of claim 9, further comprising a mode establishing controller configured to establish a reproducing mode based on the extension information, wherein the reproducing controller performs under the established reproducing mode.

11. The apparatus of claim 10, 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.

12. The apparatus of claim 10, wherein the apparatus skips the audio file if the audio file is not reproducible under the established reproducing mode.

13. The apparatus of claim 10, wherein the reproducing controller controls to continuously reproduce audio files reproducible under the established reproducing mode.

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