Content identification and management in content distribution networks
First Claim
1. A method comprising:
- receiving a content signal uploaded to a computer within a network of computers in a content distribution system;
computing a content fingerprint of the content signal, wherein the content fingerprint is derived from the content signal;
sending the content fingerprint to a database to access related metadata;
receiving related metadata from the database; and
managing use of the content signal in the content distribution system based on the related metadata, wherein managing use comprises determining from the metadata whether to permit sharing of the content signal throughout the content distribution system.

Abstract
Peer-to-peer file sharing and uploading of content to content server systems is increasing in popularity on the Internet. Content signals can be edited and combined with other content programming, and or altered in ways that make it difficult to identify using conventional techniques. Content identification based on content fingerprints is used to retrieve related metadata, which in turn, is used to manage use of the content signal in content distribution systems. The content signal is uploaded to a computer within a network of computers in the content distribution system. A content fingerprint of the content signal is computed and sent to a database to look up related metadata. The metadata is received and used to manage use of the content signal in the content distribution system based on the metadata. This can include blocking uploading or rendering of audio or video, controlling streaming of audio or video, linking to a licensing server, which provides usage control rules, etc.

6. A tangible computer readable media on which is stored instructions, which if executed by one or more programmed processors, cause the one or more programmed processors to perform operations comprising:
-
receiving a content signal uploaded to a computer within a network of computers in a content distribution system; computing a content fingerprint of the content signal, wherein the content fingerprint is derived from the content signal; sending the content fingerprint to a database to access related metadata; receiving metadata from the database; managing use of the content signal in the content distribution system based on the metadata; and determining from the metadata whether to permit sharing of the content signal throughout the content distribution system.

7. A system comprising:
-
a processor configured to compute a content fingerprint derived from a content signal; and a database configured to store content fingerprint data and metadata associated with the content signal; wherein data and metadata associated with the content signal is retrievable based on a search of content fingerprint data; wherein the processor is further configured to manage use of the content signal in a content distribution system based on the metadata associated with the content signal retrieved from the database and to determine from the metadata whether to permit sharing of the content signal throughout the content distribution system. - View Dependent Claims (8, 9, 10, 11)
