Interactive content acquisition using embedded codes
First Claim
1. A method for obtaining associated information for a multimedia content, comprising:
- receiving a content at a receiver device equipped with a watermark detector, the received content missing the associated information;
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 interval identifier identifying a specific interval of the received content, 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 metadata server identified by the Internet address; and
receiving a response to the query from the server, the response including metadata associated with the content comprising the associated information.

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.

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 or more watermarks from the received multimedia content, the received content missing an associated information, 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 interval identifier identifying a specific interval of the received content, 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 circuity to;
transmit the query to a metadata 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 comprising the associated information. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

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 received content missing an associated information, 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 interval identifier identifying a specific interval of the received content, the first field providing a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload; program code for, based on the detected watermark payload, forming a query and transmitting the query to a server identified by the Internet address; and program code for, receiving a response to the query from the server, the response including metadata associated with the content comprising the associated information.

28. A device, comprising:
-
a processor; and a memory including processor executable code, the processor executable code when executed by the processor configures the device to; extract one or more watermarks that are embedded in a multimedia content, the content missing an associated information, the extracted 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 interval identifier identifying a specific interval of the received content, the first field providing a mapping to an Internet address accessible to retrieve metadata associated with content segments identified by the watermark payload; form a query; transmit the query to a metadata server identified by the Internet address, and receive a response to the query from the server, the response including metadata associated with the content comprising the associated information.
