Abstract

Methods and devices are provided to obtain associated information for a multimedia content. One such method includes receiving a content at a receiver device equipped with a watermark detector, performing watermark detection on the received content to extract a payload of an embedded watermark. The payload comprises a first field that includes a server identifier and a second field that includes an interval identifier associated with the server identifier. The first field provides a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload. In this method, based on the detected watermark payload, a query is formed and transmitted to a server identified by the Internet address, and a response to the query is received from the server that includes metadata associated with the content.

Claims

1. A method for obtaining associated information for a multimedia content, comprising:

receiving a content at a receiver device equipped with a watermark detector;

performing watermark detection on the received content to extract a payload of one or more embedded watermarks, the payload including a first field that includes a server identifier and a second field that includes an interval identifier associated with the server identifier, the first field providing a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload;

based on the detected watermark payload, forming a query and transmitting the query to a server identified by the Internet address; and

receiving a response to the query from the server, the response including metadata associated with the content.

2. The method of claim 1, wherein value of the first field is assigned by a central authority to domain registrants, each domain registrant controlling an assignment and usage of the second field.

3. The method of claim 1, wherein a correspondence between the first field and the Internet addresses is pre-established at least in-part by a registrar server.

4. The method of claim 1, wherein the mapping is stored in the receiver device in a memory.

5. The method of claim 1, wherein the receiver device receives the mapping or the Internet address in response to a lookup request including the first field to a lookup server.

6. The method of claim 1, wherein the query is a standardized query that is used to obtain the metadata corresponding to a particular value of the interval identifier.

7. The method of claim 1, wherein the payload includes a third field that is indicative of availability of the metadata associated with a content interval that is identified by the interval identifier.

8. The method of claim 7, wherein the query is formed and transmitted to the server upon detection of a change in a value of the third field.

9. The method of claim 1, wherein the payload is further structured to include a payload type field that identifies the payload as corresponding to one of a small domain, a medium domain or a large domain.

10. The method of claim 9, wherein the payload is 50 bits long and the payload type field is a 2-bit field.

11. The method of claim 1, wherein the first field specifies a server code, the second field specifies an interval code that is associated with a specific interval of the content, and each server code is assigned by a central authority to one of a content producer, a content distributor, or a service provider.

12. The method of claim 1, wherein the metadata includes instructions that allows the receiver device to execute particular interactive services associated with a content interval that is identified by the interval identifier.

13. The method of claim 1, wherein the metadata identifies one or more of the following:

an Internet address of an interactive services server;

or

one or more parameters that indicate when and how an interactive service can be configured.

14. A device capable of receiving a multimedia content, the device comprising:

a watermark detector implemented at least in-part using electronic circuitry to detect one of more watermarks from the received multimedia content, the detected watermarks including a payload that comprises a first field that includes a server identifier and a second field that includes an interval identifier associated with the server identifier, the first field providing a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload;

a processor and a memory including processor executable instructions embodied thereupon, the instructions upon execution, cause the processor to form a query; and

a communication component implemented at least in-part using electronic circuitry to;

transmit the query to a server identified by the Internet address, and to receive a response to the query from the server, the response including metadata associated with the content.

15. The device of claim 14, wherein value of the first field is assigned by a central authority to domain registrants, each domain registrant controlling an assignment and usage of the second field.

16. The device of claim 14, wherein a correspondence between the first field and the Internet addresses is pre-established at least in-part by a registrar server.

17. The device of claim 14, wherein the mapping is stored in the receiver device and is accessible for use by the receiver device for retrieving the Internet address based on the first field.

18. The device of claim 14, wherein the communication component is configured to transmit a lookup request including the first field to a lookup server and to receive the mapping or the Internet address in response to the lookup request.

19. The device of claim 14, wherein the instructions executed by the processor form a lookup query based on a value of the first field, the communication component is configured to transmit the lookup request to a lookup server and receive the Internet address, the instructions executed by the processor further form the query as a standardized query based on the Internet address and a particular value of the interval identifier, and the communication component further configured to transmit the standardized query to a server and to receive the metadata corresponding to the particular value of the interval identifier.

20. The device of claim 14, wherein the payload includes a third field that is indicative of availability of the metadata associated with a content interval that is identified by the interval identifier.

21. The device of claim 20, wherein the instructions executed by the processor form the query upon detection of a change in a value of the third field.

22. The device of claim 14, wherein the payload is further structured to include a payload type field that identifies the payload as corresponding to one of a small domain, a medium domain or a large domain.

23. The device of claim 14, wherein the payload is 50 bits long and the payload type field is a 2-bit field.

24. The device of claim 14, wherein the first field specifies a server code, the second field specifies an interval code that is associated with a specific interval of the content, and each server code is assigned by a central authority to one of a content producer, a content distributor, or a service provider.

25. The device of claim 14, wherein the instructions executed by the processor causes the processor to use the metadata to execute particular interactive services associated with a content interval that is identified by the interval identifier.

26. The device of claim 14, wherein the metadata identifies one or more of the following:

an Internet address of an interactive services server e;

or

one or more parameters that indicate when and how an interactive service can be configured.

27. A computer program product embodied on one or more non-transitory computer readable media, comprising:

program code for receiving a content at a receiver device equipped with a watermark detector;

program code for performing watermark detection on the received content to extract a payload of one or more embedded watermarks, the payload including a first field that includes a server identifier and a second field that includes an interval identifier associated with the server identifier, the first field providing a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload;
