Abstract

A digital media player is disclosed. The digital media player can permit one or a group of users to play digital media in a convenient and user-friendly manner. Typically, a memory card stores the digital media to be played by the digital media player. After the memory card is coupled to the digital media player, the digital media player can operate to play (e.g., view) or manipulate (e.g., zoom, rotate, delete, etc.) digital media. The digital media player can also operate to archive the digital media in a reduced resolution format. The reduced resolution format is adequate for an intended output device, yet has a substantially reduced file size.

a housing having a plurality of slots for receiving at least one removable storage card, the at least one removable storage card storing digital media items; and

a processor operable to access the digital media items from the at least one removable storage card, modify the digital media items to have a reduced resolution format, and store the modified digital media items having the reduced resolution format to the at least one removable storage card or another storage card.

2. A digital media viewer as recited in claim 1, wherein the digital media items are digital images.

3. A digital media viewer as recited in claim 2, wherein the digital media items were previously stored to the at least one removable storage card by a camera.

5. A digital media viewer as recited in claim 1, wherein the at least one removable storage card is a FLASH data storage card.

6. A digital media viewer as recited in claim 1, wherein the at least one removable storage card is a memory card.

7. A digital media viewer as recited in claim 1, wherein the reduced resolution format is user-determinable.

8. A digital media viewer as recited in claim 1, wherein the reduced resolution format is substantially a VGA format.

9. A digital media viewer as recited in claim 1, wherein said digital media viewer further comprises a video output port for supplying video signals to a display device so that the modified digital media items can be displayed.

10. A digital media viewer as recited in claim 1, wherein the reduced resolution format is associated with a resolution of an Intended display device.

11. A digital media viewer as recited in claim 1,

wherein said processor accesses the digital media items or the modified digital media items and then produces digital video output, and

wherein said digital media viewer further comprises:

a digital-to-analog converter operatively connected to receive the digital video output and to produce analog video display signals; and

a video output port that outputs the analog video display signals.

12. A digital media viewer as recited in claim 11, wherein the video display signals being output are supplied to a television that displays the digital media items or the modified digital media items.

13. A digital media viewer as recited in claim 1, wherein said processor accesses the digital media items or the modified digital media items and then produces digital video output.

14. A digital media viewer as recited in claim 11, wherein the video display signals being output are supplied to a display device.

15. A dedicated digital media player, comprising:

a housing having a plurality of slots for receiving at least one removable storage card, the at least one removable storage card storing digital media items; and

a processor operable to access the digital media items from the at least one removable storage card, and to produce output signals for presenting the digital media items to one or more interested persons.

16. A dedicated digital media player as recited in claim 15, wherein at least one of the slots of said housing accepts removable storage cards having different formats.

17. A dedicated digital media player as recited in claim 15, wherein the output signals are analog video signals.

18. A dedicated digital media player as recited in claim 15,

wherein said processor accesses the digital media items and then produces digital video output, and

wherein said digital media player further comprises:

a digital-to-analog converter operatively connected to receive the digital video output and to produce analog video display signals; and

a video output port that outputs the analog video display signals.

19. A dedicated digital media player as recited in claim 18, wherein the video display signals being output are supplied to a television that displays the digital media items.

20. A dedicated digital media player as recited in claim 15, wherein said processor further modifies the digital media items to have a reduced resolution format.

21. A dedicated digital media player as recited in claim 20, wherein said processor further stores the modified digital media items having the reduced resolution format to the at least one removable storage card or another card.

22. A digital media player as recited in claim 15,

wherein the at least one removable storage card provides non-volatile semiconductor data storage, and

wherein the slots support a plurality of different storage card formats.

23. A digital media player as recited in claim 15, wherein said digital media player further supports wireless interaction with a remote controller.

24. A method for reducing resolution of media items to be commensurate with a display device for viewing media items, said method comprising:

reading high resolution media files from a first removable media storage card, the first removable data storage card having the high resolution media files pertaining to media items stored thereon in a high resolution format;

identifying a reduced resolution format to be used;

processing the high resolution media files to produce reduced resolution media files in accordance with the reduced resolution format; and

storing the reduced resolution media files to the first removable data storage card or a second data storage card, whereby the storage space consumed by the reduced resolution media files is substantially less than the storage space consumed by the high resolution media files.

25. A method as recited in claim 24, wherein the storage space consumed by the reduced resolution media files is at least one-fifth that of the storage space consumed by the high resolution media files.

26. A method as recited in claim 24, wherein the storage space consumed by the reduced resolution media files is at least one-tenth that of the storage space consumed by the high resolution media files.

27. A method as recited in claim 24, wherein the storage space consumed by the reduced resolution media files is at least one-twentieth that of the storage space consumed by the high resolution media files.

28. A method as recited in claim 24, wherein the reduced resolution format is approximately commensurate with the maximum resolution supported by the display device.

29. A method as recited in claim 24, wherein said identifying comprises:

determining whether a user-specified resolution has been set; and

selecting the user-specified resolution as the reduced resolution format when said determining determines that a user-specified resolution has been set.

30. A method as recited in claim 29, wherein said identifying further comprises:

selecting a default resolution as the reduced resolution format when said determining determines that a user-specified resolution has not been set.

31. A method as recited in claim 24, wherein the high resolution media files and the reduced resolution media files are digital files pertaining to images.
