    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.

    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 and devices are provided for using preexisting content identification information by a content distributor. Content is received by a content distributor, the content including a pre-existing watermark conveying a preexisting content identifier associated with the content. The preexisting content identifier conveyed by the preexisting watermark is detected in the content. At least one additional watermark is embedded into the content, the additional watermark conveying an additional content identifier. A mapping is created that associates the preexisting content identifier with the additional content identifier. The content embedded with the additional watermark is then for delivery to a receiver device.

    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 creating a signaling file that contains metadata and signaling data about the broadcast service being presented. The signaling file may include URLs that can be used to access signaling information for supplementary signaling and content. The signaling also contains a mapping between a first timing system and a second timing system. The first timing system may comprise the watermark timeline represented in interval s and the second timing system may comprise a DASH presentation time.

    Abstract: The disclosed technology relates to methods, devices, systems and computer program products that facilitate access to metadata associated with a content. In one example, a method is described that includes receiving a multimedia content at a receiver device, extracting a watermark message from a first segment of the multimedia content, using at least a portion of the first watermark message to obtain additional information regarding the first segment of the multimedia content that includes the first watermark message, and associating and storing one or more values of the first watermark message and the additional information. The method further includes repeating the above operations to extract additional watermark messages from additional segments of the content and to form a table or array of items that can be accessed by specifying the one or more values of the first watermark message or one or more values of the additional watermark messages.

    IPC: G06F21/10

    Abstract: Content screening operations, which can include watermark extraction and the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted by different devices that are connected via connectors such as HDMI (High-Definition Multimedia Interface (HDMI), analog composite video, DVI (Digital Visual Interface), SDI (Serial Digital Interface), DisplayPort, or networked via Ethernet or wireless. Authentication and encryption methods are disclosed that can be used to establish the trust and secure communication between devices that conduct collaborative content screening. Delegation architecture may be based on ascertained screening capabilities of the sink device wherein the source device verifies that the sink device is capable and trusted to perform partial or whole screening operations delegated by the source. Alternatively, delegation architecture may be based on ascertained screening capabilities of the source device wherein the sink device verifies that the source device is capable and trusted to provide correct content credential and content use policy (“content credential”) that is needed for the sink device to determine whether content screening should be performed, and if yes, what content screening operations should be performed.

    Abstract: Methods and devices are provided to facilitate acquisition of information associated with a multimedia content through embedded watermarks. One such method includes obtaining a server code for embedding into a content. The server code identifies a particular domain name registered to a registrant entity and provides a mapping to an Internet address of a metadata server. Upon receiving an indication that a trigger event is associated with a particular segment of the content, a first watermark payload is formed and embedded in the content. The watermark payload includes the server code, an interval code and a first trigger value. The interval code identifies the particular content segment and the first trigger value indicates that additional information associated with the particular segment is. Detection of the first trigger value from a subsequently distributed content enables a query to the metadata server for acquisition of metadata.
