    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： Auxialiary data subband samples representing an auxiliary data signal (315) are transported in a subband-coded compressed digital audio signal without decompressing the data. A pre-existing packetized data stream (305) is provided to an input of an encoder (310). Subband audio samples (406) are extracted from the packet stream and normalized (408). The data to be transported modulates data carrier subbands (SPD0, ---SPD-1, including a pseudo-noise (PN) spread spectrum signal, each subband of which has a bandwidth corresponding to those of the digital audio signal, The modulated data carrier sequence is combined with the audio subband samples (SS1, SS2---SSN-1) to form a combined signal (452), then muLtiplexed (460) into pre-existing packet stream (407). In the decoder (368), the combined signal is demodulated to recover the auxiliary data signal (672). The recovered auxiliary data signal is carried substantially inaudibly in the audio signal and is spectrally shaped according to the audio signal to enhance concealment.

    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： Broadcast audio (10) is automatically monitored for information of interest. A computer processor (12) has a memory associated therewith for storing a vocabulary (24) of keywords of interest. An audio receiver receives an audio broadcast. A voice recognition system (12, 22) associated with the audio receiver and computer processor detects (26) when one of the keywords appears in a received audio segment. A report generator (14) associated with the computer processor and responsive to the detection of a keyword generates a report detailing the detected keyword and its context. The system is particularly well suited to the verification of commercial messages and to assist in public relations efforts.
