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, systems and computer program products are provided to facilitate signaling of digital rights management (DRM) information that is carried within a multimedia content as digital watermarks. The embedded watermarks enable signaling of a change in trustworthiness of particular DRM technology, enable addition of new DRM technologies to a trusted list of technologies, and facilitate revocation of obsolete or untrustworthy technologies. Once a content is received at a receiver that is equipped with a watermark extractor, extraction of watermark symbols from the content allows the determination of change in trustworthiness of DRM technologies associated with the content.

Abstract: Methods, devices, systems and computer program products improve the detection of watermarks that are embedded in a host content by providing information indicative of a ranking of watermark payloads to watermark extractors. A watermark extractor device obtains information indicative of a ranking of a plurality of watermark payload values, where such information designates each watermark payload value within a first subset of the plurality of watermark payload values as having an associated rank value. Based at least in-part on the information indicative of the ranking, the watermark extractor device is configured to prioritize resource allocation for extraction of payload values that are designated as belonging to the first subset over payload values that are not designated as belonging to the first subset. The watermark extractor then extracts a payload value, designated as belonging to the first subset, from one or more watermarks embedded in the host content.

Abstract: Methods, devices and computer program products are described that improve acquisition of metadata that is associates with a multimedia content, such an audio or video content. In one exemplary method, the multimedia content is received at a first device that is equipped with a watermark detector and watermark extraction operations are conducted to detect a plurality of watermark messages. Each watermark message includes a server code and an interval code. In this method, a server Internet Protocol (IP) address is obtained that corresponds to a server that stores at least a portion of the metadata associated with the multimedia content. The IP address corresponds to at least one of the server codes detected from the plurality of watermark messages. According to the above method, the metadata is requested from the server having the server IP address, and a response including the metadata associated with the multimedia content is received.

Abstract: Systems, devices, methods and computer program products respond to real-time piracy of broadcast streams. One method includes receiving requests from a requesting device for a plurality segments of a real-time content, where at least one of the requested content segments differs from another segment of the plurality of segments in at least one characteristic. In response to the request, a particular version of the requested segments is transmitted to the requesting device such that a unique sequence of the transmitted segments identifies the requesting device or a user or a transaction. A communication network is then monitored to obtain a disseminated version of the real-time content, and based on the at least one characteristic of the obtained real-time content, it is determined if the real-time content includes the unique sequence of segments, and if so, one or more actions are initiated to thwart further dissemination of the real-time content.

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 computer program products are described that facilitate enhanced interactions via social media that can be enabled, at least in-part, by using various content identification techniques. Enhanced viewing of a content can be accomplished by monitoring activities of a user related to the user's accessing of a particular content and analyzing information acquired from the monitoring in conjunction with stored data related to additional users. Next, a subset of the additional users that are associated with the user or with the particular content are identified, and enhanced viewing of the particular content is enabled amongst the user and the identified subset of the additional users.

Abstract: Methods and devices are provided for embedding auxiliary information in a host content in a manner that reduces memory, bandwidth and computational complexity of the embedding and transmission systems. One methodology relates to receiving a set of watermark embedding parameters produced at a pre-processing node by pre-processing the host content. The watermark embedding parameters enable embedding each of a plurality of host content segments with any one of at least two different logical values. To embed the auxiliary information, the host content is modified on a segment-by-segment basis using the set of watermark embedding parameters and in accordance with a control signal that designates one of the at least two logical values for embedding into a selected segment of the host content. The generation of watermark embedding parameters at a pre-processing node reduces storage, transmission and computational complexity of embedding operations that can occur at locations other than the pre-processing node.

Abstract: The disclosed embodiments relate to media devices implementing new television standards, such as ATSC 3.0, which includes audio/video essence and metadata/signaling. The disclosed embodiments include techniques for confirming an association between two media devices by augmenting media content with a watermark using an upstream device, wherein the watermark conveys an identifier. The media content is sent from the upstream device to a downstream device and the watermark is detected using the downstream device. The identifier is transmitted to a server upon the detection of the watermark using the downstream device. The server identifies an association between the upstream and downstream devices upon receipt of the identifier from the downstream device.
