Usage rights to digital content are dynamically assigned. Various dynamic conditions are monitored and the usage rights are adjusted in a predetermined manner based on the status of dynamic conditions. The dynamic conditions include the time of day, the load on a server or network, or the like. The resolution of an image can be determined based on the conditions and the image can be rendered using subband decomposition techniques to permit variable resolution images to be constructed on the fly.

1. A method of dynamically assigning usage rights to digital content comprising:storing the digital content on computer media;associating a usage right with the digital content, said usage right specifying the type of use for which authorized users can use the digital content and being enforceable by a repository;determining the status of one or more dynamic conditions that are external to said usage right; andadjusting said usage right in a predetermined manner based on the status of said dynamic conditions determined in said determining step. 2. A method as recited in claim 1, wherein said adjusting step comprises adjusting the resolution of a processed image of the content that is available for use by a user. 3. A method as recited in claim 2, wherein said adjusting step comprises determining a resolution for download of the content, applying a subband decomposition algorithm to the content to create at least one sub-image, and combining sub-images created in said applying step into the processed image. 4. A method as recited in claim 1 wherein said determining step comprises determining the time of day. 5. A method as recited in claim 1 wherein said determining step comprises determining the load on a computer system used to distribute the digital content. 6. A method as recited in claim 1 wherein said adjusting step comprises adjusting a fee charged for the digital content. 7. A method as recited in claim 1 wherein said adjusting step comprises adjusting a distribution right for the digital content. 8. A method as recited in claim 1, wherein the digital content is a digital image, and the type of use is a resolution of the digital image to which a user is entitled, and said adjusting step comprises adjusting the resolution to which the user is entitled, said method further comprising:applying a subband decomposition algorithm to the image to create plural sub-images of predetermined resolutions; andcombining sub-images created in said applying step into a processed image having the resolution to which the user is entitled as adjusted in said adjusting step. 9. A method as recited in claim 8 wherein said applying step comprises applying a wavelet decomposition algorithm to the image. 10. Computer readable media having instructions for dynamically assigning a usage right to digital content, said usage right specifying the type of use for which authorized users can use the digital content and being enforceable by a repository, said media comprising;instructions for determining the status of one or more dynamic conditions that are external to said usage right; andinstructions for adjusting the usage rights in a predetermined manner based on the status of said dynamic conditions. 11. Computer readable media as recited in claim 10, wherein said instructions for adjusting comprise instructions for adjusting the resolution of a processed image of the content that is available for use by a user. 12. Computer readable media as recited in claim 11, wherein said instructions for adjusting comprise instructions for determining a resolution for download of the content, instructions for applying a subband decomposition algorithm to the content to create at least one sub-image, and instructions for combining sub-images into the processed image. 13. Computer readable media as recited in claim 10 wherein said instructions for determining comprise instructions for determining the time of day. 14. Computer readable media as recited in claim 10 wherein said instructions for determining comprise instructions for determining the load on a computer system used to distribute the digital content. 15. Computer readable media as recited in claim 10 wherein said instructions for adjusting comprise instructions for adjusting a fee charged for the digital content. 16. Computer readable media as recited in claim 10 wherein said instructions for adjusting comprise instructions for adjusting a distribution right for the digital content. 17. A method as r ecited in claim 1, wherein the type of use specified by the usage rights is at least one of the ability to print the content, the ability to distribute the content, the number of times the content can be used, and the resolution of an image of the content, and wherein said adjusting step comprises adjusting said at least one of the ability to print the content, the ability to distribute the content, the number of times the content can be used, and the resolution of an image of the content subsequent to said associating step. 18. A computer readable media as recited in claim 10, wherein the type of use specified by the usage rights is at least one of the ability to print the content, the ability to distribute the content, the number of times the content can be used, and the resolution of an image of the content, and wherein said instructions for adjusting comprise instructions for adjusting said at least one of the ability to print the content, the ability to distribute the content, the number of times the content can be used, and the resolution of an image of the content subsequent to the usage rights being associated with the content. 19. A method as recited in claim 1, wherein the digital content comprises textual content. 20. A method as recited in claim 1, wherein the digital content comprises audio content. 21. A method as recited in claim 1, wherein the digital content comprises video content. 22. A method as recited in claim 1, wherein the digital content comprises software. 23. Computer readable media as recited in claim 10, wherein the digital content comprises textual content. 24. Computer readable media as recited in claim 10, wherein the digital content comprises audio content. 25. Computer readable media as recited in claim 10, wherein the digital content comprises video content. 26. Computer readable media as recited in claim 10, wherein the digital content comprises software. 27. A method as recited in claim 1, wherein said determining step is conducted continuously. 28. A method as recited in claim 1, wherein said determining step is conducted periodically. 29. A method as recited in claim 1, wherein said determining step is conducted at the time of distribution of the digital content. 30. Computer readable media as recited in claim 10, wherein said instructions for determining comprise instructions for determining the status of one or more dynamic conditions continuously. 31. Computer readable media as recited in claim 10, wherein said instructions for determining comprise instructions for determining the status of one or more dynamic conditions periodically. 32. Computer readable media as recited in claim 10, wherein said instructions for determining comprise instructions for determining the status of one or more dynamic conditions at the time of distribution of the digital content.
