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.
