Abstract: Methods, devices, systems and computer program products facilitate accessing metadata associated with a primary audio visual content. Upon reception of a primary content, one or more watermark messages are extracted from the primary content obtain a server code and an interval code. A query to a metadata server is initiated based on the information obtained from the extracted watermark messages. In response to the query, service recovery information is received that includes information identifying one or more timed events, where each timed event identifies an operation to be performed at a corresponding instance in time as the primary content is being presented by the receiver device. One or more operations identified the timed events are initiated at the corresponding instance(s) in time.

Abstract: Methods, apparatus, and systems use embedded watermarks to determine whether the segments of a multimedia content has been rearranged. The embedded watermarks are recovered from the content and one or more attributes associated with the recovered watermarks are identified. A continuity of the content can then be assessed in accordance with the one or more attributes. The continuity assessment may be based on a variety of factors, including but not limited to a determined heartbeat of the recovered watermarks, a density, separation, location, or extent, of the recovered watermarks, as well as information associated with the watermarks, such as a stego key, channel bits, packet numbers, a fingerprint, or the like.

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.

Abstract: Methods, systems and devices enable enhanced delivery of metadata, as well as auxiliary programs and services associated with a primary content. In one method, a primary content with pre-existing watermarks is received at a content distributor device. The pre-existing watermark include specific fields that allow retrieval of a first metadata. The values and boundary locations of the symbols of the pre-existing watermark messages are determined, and symbols of a new watermark message are embedded in the primary content to render the pre-existing watermarks undetectable. The new watermark message includes symbol values that different from those in the pre-existing watermark messages and enable retrieval of a second metadata. Upon transmission of the primary content to a client device, detection of the new watermark message, and initiation of a request by the client device, access to the first or the metadata, as well as associated programs or services, are enabled.

Abstract: Methods, devices and computer program products facilitate management of multimedia content and recognition of a content that is being acoustically or optical presented using web-based technology. One method includes capturing an audio or a video content that is in acoustic or optical form via a microphone or a video camera that is coupled to an environmental sensing web-based mechanism integrated as part of a web page published by a server. Watermark or fingerprinting techniques are used to obtain identification information for the captured audio or the video content is produced, and based on the identification information, a customized response is received at the client device that includes a customized content or a customized information.

Abstract: A system for using a watermark embedded in an audio signal to remotely control a device. Various devices such as toys, computers, and appliances, equipped with an appropriate detector, detect the hidden signals, which can trigger an action, or change a state of the device. The watermarks can be used with a “time gate” device, where detection of the watermark opens a time interval within which a user is allowed to perform an action, such as pressing a button, typing in an answer, turning a key in a lock, etc.

Abstract: Methods, systems, and apparatus are disclosed which enable flexible insertion of forensic watermarks into a digital content signal using a common customization function. The common customization function flexibly employs a range of different marking techniques that are applicable to a wide range of forensic marking schemes. These customization functions are also applicable to pre-processing and post-processing operations that may be necessary for enhancing the security and transparency of the embedded marks, as well as improving the computational efficiency of the marking process. The common customization function supports a well-defined set of operations specific to the task of forensic mark customization that can be carried out with a modest and preferably bounded effort on a wide range of devices. This is accomplished through the use of a generic transformation technique for use as a “customization” step for producing versions of content forensically marked with any of a multiplicity of mark messages.
