1. A method for searching for metadata relating to media content, the method comprising:
- receiving, from a first computing device, a content signal;
transforming the content signal into two or more different hash formats to derive digital watermark data embedded in the content signal, and using the digital watermark data to retrieve metadata for the content signal, wherein the two or more different hash formats correspond to different databases, and wherein the databases store hashes of content signals and corresponding identifying information;
using the two or more different hash formats to determine identifying information from the corresponding databases; and
based in part on the identifying information, retrieving metadata for the content signal.

Abstract
Metadata for a content signal is searched by transforming the content signal into different hash formats, each being used to retrieve identifying information from corresponding databases. The identifying information enables retrieval of metadata from metadata databases. These systems and methods enable devices to access a wide array of dynamic metadata from disparate sources through queries that are derived from intrinsic content attributes.

5. A computer readable medium on which is stored instructions that, if executed by a computing device, cause the computing devices to perform operations comprising:
-
receiving, from a first computing device, a content signal; transforming the content signal into two or more different hash formats to derive digital watermark data embedded in the content signal, and using the digital watermark data to retrieve metadata for the content signal, wherein the two or more different hash formats correspond to different databases, and wherein the databases store hashes of content signals and corresponding identifying information; using the two or more different hash formats to determine identifying information from the corresponding databases; and based on the identifying information, retrieving metadata for the content signal. - View Dependent Claims (10, 11, 12)

6. A system for searching for metadata relating to media content, the system comprising:
-
a memory for receiving and storing a content signal; a computing device programmed to transform the content signal into two or more different hash formats to derive digital watermark data embedded in the content signal, and using the digital watermark data to retrieve metadata for the content signal, wherein the two or more different hash formats correspond to different databases, and wherein the databases store hashes of content signals and corresponding identifying information; the computing device further programmed to use the two or more different hash formats to obtain identifying information from the corresponding databases; and the computing device further programmed to retrieve metadata for the content signal from one or more metadata databases using the identifying information. - View Dependent Claims (7, 8, 9)
