Abstract

An original content item and a first derivative content item are stored in a storage, the derivative content item being associated with the original content item. A request is received from a remote device, the request including information about the remote device and an identifier associated with the original content item. The first derivative content item is provided to the remote device upon determining that the remote device has a property that does not match a corresponding property of the original content item, and a second derivative content item that is a derivative of the original content item is generated, the second derivative content item having a property that matches a corresponding property of the remote device. The second derivative content item is provided to the remote device.

5. The method of claim 1 wherein determining that the remote device has a property that does not match a corresponding property of the original content item comprises determining that the remote device has a display resolution that does not match a pixel resolution of the original content item.

6. The method of claim 5 wherein generating a second derivative content item comprises generating a second derivative content item that has a pixel resolution that matches the display resolution of the remote device.

7. The method of claim 1 wherein determining that the remote device has a property that does not match a corresponding property of the original content item comprises determining that the remote device has a spectral resolution that does not match a spectral resolution of the original content item.

8. The method of claim 7 wherein generating a second derivative content item comprises generating a second derivative content item that has a spectral resolution that matches the spectral resolution of the remote device.

9. The method of claim 1 wherein determining that the remote device has a property that does not match a corresponding property of the original content item comprises determining that the original content item is encoded according to a first encoding algorithm and the remote device is not capable of decoding the encoded original content item.

10. The method of claim 9 wherein generating a second derivative content item comprises generating a second derivative content item that is encoded according to a second encoding algorithm that can be decoded by the remote device.

11. The method of claim 1 wherein receiving a request from a remote device comprises receiving an HTTP request from the remote device.

12. The method of claim 1, further comprising invalidating the derivative content items when the original content item is modified.

13. The method of claim 1, further comprising invalidating the derivative content items when a creation date of the original content item is more recent than the creation date of the derivative content items.

14. A computer-implemented method, comprising:

storing an original image and a thumbnail image in a storage of a server, the thumbnail image being derived from the original image;

receiving a first request from a first remote device, the first request including information about the first remote device and an identifier that identifies the original image;

determining that the resolution of the first remote device does not match the resolution of the original image;

providing the thumbnail image to the fist remote device;

generating a first derivative image that is a derivative of the original image, the first derivative image having a resolution that matches the resolution of the first remote device; and

providing the first derivative image to the first remote device.

15. The method of claim 14 further comprising

receiving a second request from a second remote device, the second request including information about the second remote device and an identifier that identifies the original image;

determining that the resolution of the second remote device does not match the resolution of the original image, and that the second remote device has a resolution that is more similar to the first derivative than the original image or the thumbnail image;

providing the first derivative to the second remote device;

generating a second derivative of the original image, the second derivative having a resolution that matches the resolution of the second remote device; and

providing the second derivative of the original image to the second remote device.

16. A computer-implemented method, comprising:

storing original content items and derivative content items in folders, each folder storing one original content item and one or more derivative content items that are derived from the original content item; and

adaptively providing content items to remote devices, including

for each request from a remote device requesting a particular original content item, determining whether any content item in the folder associated with the particular original content item has properties that match corresponding properties of the remote device, and

if none of the content items in the folder associated with the particular original content item has properties that match corresponding properties of the remote device,

providing one of the content items in the storage having properties that more closely match corresponding properties of the remote device,

generating a new derivative content item that is a derivative of the original content item, the new derivative content item having properties that match corresponding properties of the remote device, and

sending the new derivative content item to the remote device.

17. The method of claim 16 wherein storing the original content items and derivative content items comprise storing original images and derivative images in the folders.

18. The method of claim 16 wherein determining whether any content item in the folder associated with the particular original content item has properties that match corresponding properties of the remote device comprises determining whether any content item in the folder associated with the particular original content item has a pixel resolution that matches a display resolution of the remote device.

19. A computer-implemented method, comprising:

receiving requests from remote devices requesting multimedia content items;

generating new derivative multimedia content items if currently available original multimedia content items and derivative multimedia content items do not match the properties of the remote devices, the new derivative multimedia content items more closely matching the properties of the remote devices than the currently available original and derivative multimedia content items; and

adaptively providing the original or derivative multimedia content items to the remote devices by initially providing currently available original or derivative multimedia content items that most closely match the properties of the remote devices, then providing the new derivative multimedia content items as the new derivatives become available.

20. The methods of claim 19, further comprising organizing the original and derivative multimedia content items in folders, each folder including one of the original multimedia content items and derivative multimedia content items that are derived from the original multimedia content item.

21. The method of claim 19 in which generating new derivative multimedia content items if currently available original multimedia content items and derivative multimedia content items do not match the properties of the remote devices comprises generating new derivative multimedia content items if currently available original multimedia content items and derivative multimedia content items do not match the display resolutions of the remote devices.
