摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： Methods, apparatus, and systems for signal continuity assessment using embedded watermarks are provided. 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.

摘要： Systems, methods, devices and computer program products are provided that improve stego key management of watermarking systems and reduce the impact of leaked secrets related to watermark embedding and extraction operations. In the event that a watermark extractor is compromised and its extraction stego key is revealed, new extraction stego key sets are generated and assigned to a particular group of devices with similar security features. The new extraction stego key sets have significant overlap with one another, and can be retired once a device within the particular group of devices is compromised. The described techniques are complementary to other security enhancement practices, such as obfuscation and tamper resistant techniques, to strengthen the security of a watermarking system.

摘要： 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.

摘要： 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.

摘要： Methods, devices, and computer program products facilitate the application of a content use policy based on watermarks that are embedded in a content. Watermark extraction and content screening operations, which can include the application of content usage enforcement actions, may be organized such that some or all of the operations can be conducted at different times by different devices. The watermark extraction results can be stored in a secure location and accessed by other devices at different times. These operations can be conducted by one or more trusted devices that reside in a home network. The home network can also include a gateway device that can coordinate the operations of the various network devices and/or delegate the various watermark extraction and content screening operations.
