Abstract

The disclosure describes a method of connecting multimedia content to a network resource. This method operates in a computer network environment. Operating in a network connected device, the method extracts an identifier from a media signal, such as from a digital watermark, perceptual hash, or other machine extracted signal identifier. It then sends the identifier to a network along with context information indicating device type information. From the network, the method receives related data associated with the media signal via the identifier. The related data is adapted to the network connected device based on the device type information. This device type information may include a display type, so that the related date may be formatted for rendering on the display type of the device. This device type information may also include a connection speed so that the related data may be optimized for the connection speed of the device.

Claims

1. A method comprising:

receiving an identifier extracted from a media signal at a network connected device, wherein the identifier is configured for identifying metadata for the media signal, wherein the metadata includes a descriptor and a link to a network service; and

using the descriptor to initiate a search at the network service in response to a user selection at the network connected device.

2. The method of claim 1, wherein the identifier comprises a digital watermark embedded in the media signal.

3. The method of claim 1, wherein the identifier comprises a hash of attributes of the media signal.

4. The method of claim 3, wherein the attributes comprise frequency components of the media signal.

5. The method of claim 1, further comprising:

providing a device context for the network connected device; and

formatting the metadata according to the device context.

6. The method of claim 5, wherein the metadata comprises metadata tags in XML format, and the metadata tags are configured to format the metadata for display on the network connected device.

7. A system comprising

a network of computing devices;

and

a network connected device configured to extract an identifier from a media signal and send the identifier to the network, wherein the identifier is configured for identifying metadata for the media signal, and wherein the metadata includes a descriptor and a link to a network service;

wherein a computing device in the network of computing devices is configured to receive the metadata and initiate a search at the network service, in response to a user selection, using the descriptor.

8. The system of claim 7, wherein the identifier comprises a digital watermark embedded in the media signal.

9. The system of claim 7, wherein the identifier comprises a hash of attributes of the media signal.

10. The system of claim 9, wherein the attributes comprise frequency components of the media signal.

11. The system of claim 7, wherein the network connected device is configured to provide a device context and the metadata is formatted according to the device context.

12. The system of claim 11, wherein the metadata comprises metadata tags in XML format, and the metadata tags are configured to format the metadata for display on the network connected device.

13. The system of claim 11, wherein the media signal includes music and the identifier is a digital fingerprint contained within the music.

14. The system of claim 11, wherein the network service includes an internet search engine.

15. A method comprising:

receiving perceptible attributes of a media signal dynamically derived at a network connected device, wherein the attributes are configured for identifying metadata for the media signal, wherein the metadata includes a descriptor and a link to a network service;

using the descriptor to initiate a search at the network service in response to a user selection at the network connected device.

16. The method of claim 15, wherein the attributes comprise frequency components of the media signal.

17. The method of claim 15, further comprising:

providing a device context for the network connected device; and

formatting the metadata according to the device context.

18. The method of claim 17, wherein the metadata comprises metadata tags in XML format, and the metadata tags are used to format the metadata for display on the network connected device.

19. The method of claim 15, wherein dynamically deriving includes computing a hash.

20. The method of claim 15, further comprising caching in memory the metadata of the media signal, wherein the memory comprises a cache of metadata for previously identified media signals.
