    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.

    Abstract: A watermark-based dynamic ad insertion (DAI) technique for presenting different users of content different advertisements based on the user's profile for content viewed on broadcast channels or in multichannel video programming distributor (MVPD) channels. A number of solutions issues with watermark-based DAI are presented. Interoperability is addressed by providing a multiplexing technique so that the DAI watermarks do not interfere with other watermarks, such as ATSC 3.0 watermarks. Reliability is addressed by providing a matched filtering technique. Security is addressed by providing a mutual authentication technique.

    Abstract: Methods, devices, systems and computer program products enable enhances delivery and use of metadata that is associated a primary multimedia content. Watermarks that are detected by a watermark extractor produce an indication as to a state of the watermark detector as being in one of a an unmarked content state, a marked content state or a gap state, and cause the watermark extractor to transition from one state to another state based on event that are recognized based a failure or a success in detecting watermarks, an indication of low content activity and a previous state of the watermark extractor. The events and states associated with the watermark extractor further allows retrieval of new metadata associated with the primary content, use of an existing metadata in a modified manner or a change in presentation of a secondary content that is associated with the primary content.

    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, 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: Systems, devices, methods and computer program products improve various aspects of a content management system. In one scenario, one or more contents are accessed at a content handling device. The content handling device is configured to operate using multiple abstraction layers including an application layer, an operating system layer, a firmware layer and a hardware layer. Content management operations are conducted on the one or more contents using at least two abstraction layers. Such content management operations include conducting watermark extraction and content screening operations at a first layer for a first watermark message having a first value, conducting watermark extraction and content screening operations at a second layer for a second watermark message having a second value, and initiating one or more enforcement actions corresponding to the first value and the second value based at least in-part on respective results of the content screening.

    Abstract: Methods, devices, systems and computer program products facilitate embedding and extraction of transactional watermarks into and from a video content. One method for selecting an area for watermark insertion includes selecting a candidate area within a frame of the video content that is smaller in size that the frame itself, adding a first and a second watermark value to obtain corresponding first and second versions of the area, add noise to each of the first and second versions, and perform watermark extraction operations to obtain corresponding correlation values for the selected area. The above operations are repeated using different areas that are selected at pseudo-random offset values from the previously selected areas until the entire video frame is exhausted. One or more areas with the highest correlation value(s) are selected and designated as areas that are suitable for watermark insertion.
