Abstract

Content identifiers are associated with respective metadata. Through use of the metadata, a user'"'"'s experience with the content can be enhanced. A variety of other arrangements are also detailed.

Claims

1. A method comprising:

at a first computer, receiving from a first device a first content identifier previously determined through a first type of operation;

at said first computer, receiving from a second device a second content identifier previously determined through a second type of operation different than the first;

from said first computer, forwarding at least part of said first content identifier to a second computer, based on a class to which said first content identifier belongs;

from said first computer, forwarding at least part of said second content identifier to a third computer, based on a class to which said second content identifier belongs;

at said first device, receiving first and second metadata corresponding to said first and second content identifiers, from first and second different metadata sources, respectively.

2. The method of claim 1 wherein the first type of operation is an audio watermark decoding operation.

3. The method of claim 1 wherein the first type of operation is a video watermark decoding operation.

4. The method of claim 1 wherein the first type of operation is discerning a machine readable indicia distinct from a digital watermark.

5. A method comprising:

at a first device, applying a first process to a first object to yield a first content identifier;

at said first device, applying a second process different than the first to a second object, to yield a second content identifier;

from the first device, sending the first content identifier to a remote computer, and sending the second content identifier to said same remote computer;

receiving, from one or more remote sources, at least one metadata corresponding to the first content identifier, and at least one metadata corresponding to the second content identifier;

wherein said received metadata is of at least first and second different types, said different types being selected from the consisting of;

a URL, a web page;

content ownership information;

content rights information;

software;

delivery of audio data;

delivery of video data;

presentation of an advertisement; and

initiation of an object-based action.

6. A method of compiling a data structure used for associating content identifiers with related metadata, comprising:

receiving a first identifier associated with a first party;

receiving first information related to said first identifier;

receiving a second identifier associated with a second party unrelated to the first party;

receiving second information related to said second identifier; and

storing said received identifiers and information.

7. The method of claim 6 that includes, in a first session, receiving said first identifier, and in a subsequent later session, receiving the first information related to said first identifier.

8. The method of claim 6 that includes receiving at least some of said first information from a second party distinct from said first party.

9. The method of claim 8 that includes receiving additional first information from a third party distinct from the first and second parties.
