摘要： Methods, devices and computer program products allow improved detection of watermarks into and from a multimedia content. One method for detecting watermarks from a host content includes performing watermark extraction to obtain a first sequence of watermark symbols from the host content and generating a plurality of predicted watermark templates. Each template corresponds to a sequence of watermark symbols that is predicted based on the first sequence of watermark symbols. A section of the host content is processed to obtain a candidate sequence of watermark symbols and correlation operations between the candidate sequence of watermark symbols and symbols of the predicted watermark templates are performed until a correlation result that is indicative of a successful watermark detection is obtained. An indication that the candidate sequence of watermark symbols represents at feast a portion of a reliably extracted watermark message can then be produced.

摘要： Methods, devices and computer program products allow embedding and detection of watermarks into and from a multimedia content. One watermark embedding method includes selecting a content segment that lacks inherent features for embedding of watermarks without producing perceptible artifacts, and obtaining a first dither pattern corresponding to a first watermark symbol of a watermark symbol alphabet, where each symbol is associated with a particular dither pattern. Further, each particular dither pattern, upon combination with the multimedia content segment that lacks inherent features, produces a composite content segment without perceptible artifacts. By combining the first dither pattern with the multimedia content segment that lacks inherent features, a first composite content segment with the first embedded watermark symbol is produced. The detection of watermarks messages can be carried out quickly by examining a small portions of the multimedia because even the featureless content segments include embedded watermarks.

摘要： Techniques for thwarting piracy of real-time content such as broadcast streams are described. In one technique, when portions of a real-time content is received at a user device, the device embeds a particular code in the received content that associates the real-time content to that user device. When further portions of the real¬ time content that has one or more codes is received at the user device, the device determines if the particular code matches the one or more codes that are incorporated into the real-time content, and if a match if found, one of more actions is initiated at the user device to thwart further dissemination of the real-time content. The initiated actions can interfere with the playback of the real-time content or provide warning messages, and thus eliminate or discourage the use of the user device as a source of real-time content piracy.

摘要： 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 feast 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.

摘要： Methods, devices and computer program products facilitate conditional access to a content embedded with watermarks. For such a content, when copy control rules associated with an embedded watermark message prohibits unconditional access to the content, it is determined whether or not an exception to the copy control rules exists, and if an exception to the copy control rules exists, the content is conditionally accessed. Additional watermark messages can be extracted while the content is being conditionally accessed, and based on the additionally extracted watermark messages, it is verified that conditional access to the content has been fulfilled.

摘要： Method, devices, systems and computer program products are described that improve speed and accuracy of watermark detection from multimedia content, and allow faster and better content recognition. One technique for improving detection of boundaries of an embedded multimedia content segment includes detecting a synchronization header and a full watermark from the multimedia content, constructing a predicted watermark segment that is positioned at a predicted distance from the synchronization header, and comparing the group of candidate watermark symbols obtained from the multimedia content to the first predicted watermark segment to obtain a match. The disclosed techniques enable extraction of watermarks from short content segments, and can utilize a shortened payload design to establish media time during content usage.

摘要： 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.

摘要： Methods, devices, systems and computer programs facilitate presentation of a second content in synchronization with a first content. In one method, at least a portion of a first content that is being presented by a first device is received at a second device. The first content includes substantially imperceptible watermarks that are embedded in one or more components of the first content. A first watermark detection result is obtained by performing a watermark detection operation. Additionally, a second watermark detection result associated with the first content is received at the second device from a device other than the second device. The first watermark detection result and the second watermark detection result are augmented to obtain a combined watermark detection result, and the combined detection result is used to enable presentation of a second content in synchronization with the first content.

摘要： Methods, devices, systems and computer program products facilitate embedding and extraction of transactional watermarks into and from a video content. One such method includes selecting a first number of frames from a video content and performing temporal and a spatial psychovisual analysis on the selected frames. For each selected frame, at least one area for insertion of watermarks is identified. A first and a second watermark symbol is embedded separately in the identified area(s), and the embedded frames are re-encoded to obtain a first and a second alternative data. An inserter manifest is formed that includes the first and the second alternative data to enable insertion of a watermark into the video content by selecting one or the other of the first and second alternative data for insertion into the video content.
