Abstract

The present application relates generally to content management (e.g., managing audio and video items in portable devices). One claim recites a method comprising: utilizing electronic memory housed in a portable device, maintaining a listing of up to N identifiers associated with previously accessed audio or video items, where N is an integer, and where each previously accessed audio or video item has an identifier associated therewith; utilizing a programmed electronic processor housed in the portable device, i) restricting access to a new audio or video item if an identifier associated with the new audio or video item is one of the N identifiers associated with the previously accessed audio or video items, or ii) limiting a number of content items each with a different user identifier associated therewith that can be accessed in a certain amount of time. Of course, other claims and combinations are provided as well.

Claims

1. A method comprising:

utilizing electronic memory housed in a portable device, maintaining a listing of up to N identifiers associated with previously accessed audio or video items, where N is an integer, and where each previously accessed audio or video item has an identifier associated therewith;

utilizing a programmed electronic processor housed in the portable device, i) restricting access to an encountered audio or video item if an identifier associated with the encountered audio or video item is one of the N identifiers associated with the previously accessed audio or video items, or ii) limiting a number of content items each with a different user identifier associated therewith that can be accessed in a certain amount of time.

2. The method of claim 1 where N is decided by rendering rules associated with the encountered audio or video item.

3. The method of claim 1 where N is decided by the portable device.

4. The method of claim 1 wherein N comprises 10 or more.

5. The method of claim 1 where the certain amount of time is decided by the portable device.

6. A portable device comprising instructions stored in memory, said instructions are executable by said portable device to perform the acts of claim 1.

7. A portable device comprising instructions stored in memory, said instructions are executable by said portable device to perform the acts of claim 1.

8. A computer readable media comprising instructions stored thereon to cause a multi-purpose electronic processor to perform the acts of claim 1.

9. The method of claim 1 where at least one of the N identifiers can be replaced if an audio or video item associated with an identifier to be replaced has not been accessed for a certain period of time.

10. The method of claim 9 in which the existing identifier listed in the listing of N identifiers cannot be replaced with an identifier associated with the encountered audio or video item when the audio or video item associated with the existing identifier has been accessed within the certain period of time.

11. The method of claim 9 where the certain period of time is influenced by a number of times the audio or video item associated with the identifier to be replaced has been rendered.

12. A portable device comprising instructions stored in memory, said instructions are executable by said portable device to perform the acts of claim 11.

13. A computer readable media comprising instructions stored thereon to cause a multi-purpose electronic processor to perform the acts of claim 11.

14. The method of claim 11 where if the audio or video item associated with the identifier to be replaced has been rendered at least a predetermined number of times, the identifier is tracked for a longer time relative to other identifiers.

15. A portable device comprising instructions stored in memory, said instructions are executable by said portable device to perform the acts of claim 14.

16. A computer readable media comprising instructions stored thereon to cause a multi-purpose electronic processor to perform the acts of claim 14.

17. The method of claim 9 where the identifier can be replaced dependent upon a difference equation involving an access or rendering count.

18. The method of claim 17 where the access or rendering count for tracked identifiers is decremented or reduced after the expiration of a set time segment, and the identifier also can be replaced if it has a zero count.

19. A portable apparatus comprising:

electronic memory comprising a listing of up to N identifiers associated with previously accessed audio or video content items, where N is an integer, and where each previously accessed audio or video content item has an identifier associated therewith;

an electronic processor programmed for;

i) restricting access to an encountered content item if an identifier associated with the encountered content item is one of the N identifiers associated with the previously accessed audio or video content items, or

ii) limiting a number of content items each with different user identifier associated therewith that can be accessed in a certain amount of time.

20. The portable apparatus of claim 19 in which said electronic memory is operating to restrict access to the encountered audio or video item.
