METADATA ACQUISITION USING EMBEDDED CODES

摘要

Methods and devices are provided to obtain metadata associated with multimedia content. One method includes performing watermark detection on a content that is received at a receiver device to detect one or more watermarks. At least one of the detected watermark includes a payload with a server code and an interval code. The method includes forming a uniform resource locator (URL) based on the watermark payload. The URL includes a first section with server domain name the includes at least a portion of the server code. The URL also includes a second section that includes at least a portion of the interval code. Upon transmission of a request based on the URL using a hypertext transfer protocol (HTTP) for delivery to a metadata server, a response is received that includes metadata associated with the content.
