Methods and arrangements employing digital content items
First Claim
1. A digital watermark detection method for use with a digital content item, the method comprising:
- receiving an identification of a sub-portion of the digital content item through a graphical user interface of a software-configured processing device; and
applying a digital watermark detection procedure only to the sub-portion, wherein if the digital content item is a composite of plural digitally watermarked portions, a tendency of a digital watermark in a dominant element of the composite to dominate a digital watermark detection procedure to the exclusion of other digital watermarks is overcome.

Abstract
Methods and arrangements for identifying content, and employing such identification, are detailed. One method embeds a plural-bit digital watermark into content, but first checks to see if the content is previously watermarked. Another method applies a digital watermark detection procedure to only a sub-portion of a digital content item. Yet another arrangement involves plural-portion content, where one portion is watermarked with first data governing its rights management, and another portion is watermarked with second data governing its rights management. Still another method concerns distribution of content items, where each is watermarked with a unique ID as part of the distribution process. Yet another method concerns deriving an identifier from content, and using the content to access related metadata from a remote computer system. Still other methods concern arrangements for recognizing content, and then providing links to information about the content creator, etc., in response. A variety of other technologies and improvements are also detailed.

- 2. A computer readable medium storing digital content comprising plural portions, wherein a first portion is digitally watermarked with first data that governs rights management of the first portion in a processing device responsive thereto, and a second portion is digitally watermarked with second data that governs rights management of the second portion in a processing device responsive thereto.

4. A method of distributing plural items of digital content, the method comprising:
using a software-configured processing device to digitally watermark each of the items of content with a unique plural-bit identifier in the course of distributing the items, wherein the watermarking is automated and proceeds without an operator'"'"'s attention as part of a content distribution process.
-
5. A metadata method comprising:
-
rendering a first item of digital content on a software-configured processing device; and receiving an input from a user in conjunction with a screen of a user device, wherein the user input causes metadata related to the first item of digital content to be identified in a database in a remote computer system, and an action to be taken based thereon. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A metadata method comprising:
-
receiving a first digital content item comprising a file with header data and content data; deriving first content identification information from the content data of the first digital content item using a software-configured processing device; transmitting the first content identification information to a remote computer system, and as a consequence, receiving a first set of metadata related to the first content item; taking an action based on the received first set of metadata; receiving a second digital content item, also comprising a file with header data and content data, wherein the second digital content item is by an artist different than the first digital content item; deriving second content identification information from the content data of the second digital content item; transmitting the second content identification information to the remote computer system, and as a consequence, receiving a second set of metadata related to the second content item; and taking an action based on the received second set of metadata, wherein at least one of the actions includes displaying information based on the received metadata. - View Dependent Claims (21, 22)

23. An apparatus comprising:
-
a user interface configured to receive an identification of a sub-portion of a digital content item; a processor configured to apply a digital watermark detection procedure to only the sub-portion, wherein if the digital content item is a composite of plural digitally watermarked portions, a tendency of a digital watermark in a dominant element of the composite to dominate a digital watermark detection procedure to the exclusion of other digital watermarks is overcome.

24. An apparatus comprising:
a processor configured to digitally watermark each of a plurality of items of content with a unique plural-bit identifier in the course of distributing the plurality of items, wherein the watermarking is automated and proceeds without an operator'"'"'s attention as part of a content distribution process.
-
25. An apparatus comprising:
-
a screen configured to render a first item of digital content on the apparatus; a user interface configured to receive an input from a user; and a processor configured to; identify, in a remote database, metadata related to the first item of digital content; and take an action based upon the identification of the first item of digital content.

26. An apparatus comprising:
-
a receiver configured to; receive a first digital content item, wherein the first digital content item comprises a file with header data and content data; and receive a second digital content item, wherein the second digital content item comprises a file with header data and content data, wherein the second digital content item is by an artist different than the first digital content item; a processor configured to; derive first content identification information from the content data of the first digital content item; and derive second content identification information from the content data of the second digital content item; a transmitter configured to; transmit the first content identification information to a remote computer system; and transmit the second content identification information to the remote computer system; the receiver further configured to; receive a first set of metadata related to the first content item in response to the transmitted first content identification information; and receive a second set of metadata related to the second content item in response to the transmitted second content identification information; and the processor further configured to; take an action based on the received first set of metadata; and take an action based on the received second set of metadata, wherein at least one of the actions includes displaying information based on the received metadata.
