Abstract

In one embodiment, a method is provided. The method includes evaluating local codecs of a cellular telephone. The method further includes playing a content file with a media player on the cellular telephone. The method also includes accessing encoded media referred to by the content file in a format determined based on local codecs of the cellular telephone.

Claims

1. A method, comprising:

evaluating local codecs of a cellular telephone;

playing a content file with a media player on the cellular telephone; and

accessing encoded media referred to by the content file in a format determined based on local codecs of the cellular telephone.

2. The method of claim 1, further comprising:

receiving the content file at the cellular telephone.

3. The method of claim 1, further comprising:

downloading the encoded media from a remote storage device.

4. The method of claim 3, further comprising:

playing the encoded media with the media player using a local codec of the cellular telephone.

5. The method of claim 4, wherein:

the media is a movie.

6. The method of claim 5, wherein:

the movie is in a format decodable using an MPEG4 codec.

7. The method of claim 5, wherein:

the movie is in a format decodable using a 3GPP codec.

8. The method of claim 4, wherein:

the media is a still picture.

9. The method of claim 8, wherein:

the picture is in JPEG format.

10. The method of claim 8, wherein:

the picture is in PNG format.

11. The method of claim 4, wherein:

the media is a sound.

12. The method of claim 11, wherein:

the sound is in WAV format.

13. The method of claim 1, further comprising:

signaling an error when encoded media referred to by the content file in a format determined based on local codecs of the cellular telephone is not available.

14. The method of claim 1, wherein:

the method is executed by a processor responsive to instructions embodied in a machine-readable medium.

15. A system, comprising:

a cellular telephone including;

a processor;

a display coupled to the processor;

a network interface coupled to the processor;

a local storage medium coupled to the processor;

a set of codecs embodied in the local storage medium;

a media player embodied in the local storage medium;

wherein;

the media player is to play content in content files, the content files with references to encoded media, and the media player is to access encoded media through the network interface based on codecs of the set of codecs.

16. The system of claim 15, further comprising:

means for receiving commands from a user.

17. The system of claim 15, further comprising:

a user input interface.

18. The system of claim 15, wherein:

the media player is further to play encoded media using a codec of the set of codecs.

19. The system of claim 15, wherein:

the encoded media is one of a movie, a still picture or a sound.

20. A method of playing encoded media referred to in a content file played by a media player on a cellular telephone, comprising:

evaluating local codecs of the cellular telephone;

playing the content file;

accessing encoded media referred to by the content file in a format determined based on local codecs of the cellular telephone; and

playing the encoded media with the media player using a local codec of the cellular telephone.

21. The method of claim 20, wherein:

the encoded media is one of a movie, a still picture or a sound.

22. The method of claim 20, firther comprising:

downloading the encoded media from a remote storage device.

23. The method of claim 20, further comprising:

determining encoded media in a format determined based on local codecs of the cellular telephone is not available; and

signaling an error responsive to determining encoded media in a format determined based on local codecs of the cellular telephone is not available.
