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： Methods, devices and computer program products facilitate the extraction of embedded watermarks in the presence of content distortions. Pre-distorted synchronization templates are used to detect synchronization portions of embedded watermark frames. A pre-distorted synchronization template that best matches the synchronization portion of the embedded watermark frame produces an estimation of one or more distortions that are present in the content. The remainder of watermark frame can be evaluated based on the outcome of the comparison.

摘要： Apparatus and methods are provided for embedding or embedding digital data into an analog host or cover signal. A distributed signal feature of the cover signal in a particular domain (time, frequency or space) is calculated and compared with a set of predefined quantization values corresponding to an information symbol to be encoded. The amount of change required to modify the signal feature to the determined target quantization value is calculated and the cover signal is modified accordingly to so change the feature value over a predefined interval. Information symbols are extracted by the opposite process. In one embodiment, the predefined value is a short term autocorrelation value of the cover signal.

摘要： Methods, devices and computer program products enable embedding and extraction of multiple watermark messages in a coordinated fashion to improve watermark transparency, robustness against impairments, security, and computational complexity of embedding and extraction of watermarks. Coordinated watermark embedding and extraction operations take advantage of a pre-defined relationship between the symbols of two watermark messages. The improved aspects of the watermarking system provide significant value to content owners, content distributors, and consumers at a small incremental cost.

摘要： 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.

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, 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. These operations can be conducted by one or more trusted devices that reside in a networked environment. Real-time access to a content can also be facilitated by utilizing existing watermark extraction records. To facilitate real-time access to the content, the extraction records may contain segmented authentication information that correspond to particular segments of the content that is being accessed. Additionally, or alternatively, new watermark extraction operations can be conducted in real-time to produce new watermark extraction records.

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.
