Abstract

The present disclosure relates generally to audio and video processing. One claim recites a portable apparatus comprising: electronic memory comprising one or more identifiers, each of the identifiers being associated with previously accessed audio or video items, with each previously accessed audio or video item including an identifier associated therewith; and a logic processor programmed for: a. restricting access to an encountered audio or video item if an identifier associated with the encountered audio or video item is one of the one or more identifiers associated with the previously accessed audio or video items, and b. limiting a number of content items with different user identifiers that can be accessed in a predetermined amount of time. Other claims and combinations are provided as well.

Claims

1. A portable apparatus comprising:

electronic memory comprising one or more identifiers, each of the identifiers being associated with a respective previously accessed audio or video item, with each previously accessed audio or video item including an identifier associated therewith;

a logic processor programmed for;

a. restricting access to an encountered audio or video item if an identifier associated with the encountered audio or video item is one of the one or more identifiers associated with the previously accessed audio or video items, and

b. limiting a number of content items with different identifiers that can be accessed in a predetermined amount of time.

2. The portable apparatus of claim 1 where the predetermined amount of time is decided by the portable device.

3. The portable apparatus of claim 1 in which one identifier from the one or more 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.

4. The portable apparatus of claim 1 where at least one identifier from the one or more 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.

5. The portable apparatus of claim 4 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.

6. The portable apparatus of claim 4 where if the audio or video item associated with the one identifier to be replaced has been rendered at least a predetermined number of times, the one identifier is tracked for a longer time relative to other identifiers.

7. The portable apparatus of claim 4 where the one identifier can be replaced dependent upon a difference equation involving an access or rendering count.

8. The portable apparatus of claim 7 where the access or rendering count for tracked identifiers is decremented or reduced after the expiration of a set time, and the one identifier also can be replaced if it has a zero count.
