Content Identifier

Abstract: A method of performing digital asset management of media content. In this method, a watermark reader device reads a watermark embedded into media content. The watermark conveys watermark information, such as a content identifier and creator identifier. The reader forwards the watermark information to a router. The router then uses the watermark information to find a metadata database identifier. It then sends a request for metadata along with the watermark information to the metadata database identified by the metadata database identifier. The metadata database uses the watermark information to find related metadata for the media content and sends the related metadata to the reader device.

Abstract: A method of associating a content object with metadata uses a combination of a content identifier and a bounding identifier to enable handling of disparate sets of content identifiers for content objects with potentially conflicting content identifiers. The method receives a content identifier for a content object from among a set of content identifiers. It provides a unique bounding identifier for the set of content identifiers. This unique bounding identifier is used in combination with the content identifier to form a globally unique identifier for the content object. This globally unique identifier is associated with a metadata source, which enables routing of a user to the metadata source.

Abstract: A system for tracking usage of digital content on user devices. Content sites for distributing digital content over a computer readable medium to users. The content sites associate unique content identifier with the content associated. Electronic stores coupled to a network sell licenses to play digital content data to users. The licenses contain a unique transaction identifier for uniquely identifying the transaction, and the licenses contain a unique item identifier for uniquely identifying at least one item in the transaction. Content players, which receive from the network the licensed content data, are used to play the licensed content data. The content players produce a purchase identifier based upon the mathematical combination of the content identifier, the transaction identifier and the item identifier.

Abstract: A network includes one or more client computers which can retrieve Web pages and supplemental content items, such as advertisements, from one or more server computers, for display or other processing. Each Web page can have fixed content, one or more fixed URL's identifying supplemental content items to be, for example, displayed at particular locations on the Web page, and one or more sets of conditional items, with each conditional item set comprising content item(s) or content item identifier(s), such as URL's, and personal selection criteria to be used in selecting one of the content item(s) or identifier(s) to be, for example, displayed at a respective location on the Web page. When a client computer receives a Web page from a server computer, it (that is, the client computer) will, for example, display the fixed Web page content and, obtain supplemental content items identified by the fixed URL's to be displayed along with the fixed content. In addition, the client computer will process each set of conditional items in conjunction with personal information maintained by the client computer and selection criteria for the set to identify one of the conditional content item(s) to be displayed, or one of the conditional item identifier(s) to be used in obtaining a supplemental content item to be displayed along with the Web page. Since the client computer determines the particular conditional content or content identifier based on selection criteria provided with the Web page, and personal information maintained by the client computer itself, the personal information need not be provided to or otherwise obtained by the server computer to allow for personalization of the Web page.
