摘要:
The present invention relates generally to methods usable with handheld devices (e.g., music players or cell phones) and cell phones. One claim recites a cell phone including: an input or interface to receive first content corresponding to audio or video; a media player to render audio or video; an analyzer to derive a plural-bit identifier from portions of the first content representing audio elements of the audio or video picture elements of the video; data indicating at least some capabilities of the media player; and a controller to control: i) communicating the plural-bit identifier and the data indicating the at least some capabilities of the media player to a network resource to obtain enhanced content therefrom, the enhanced content being enhanced relative to the first content, and the enhanced content being associated with the plural-bit identifier and the media player; and ii) obtaining the enhanced content from the network resource. Of course, other claims and combinations are provided as well.
摘要:
A method of detecting an embedded signal in a media signal. The method comprises receiving blocks of the media signal and computing a detection metric for the blocks. The detection metric comprises a measure of coincidence of detection parameters of different blocks. The method performs subsequent detection operations based on the measure of coincidence of the detection parameters.

Two or more digital watermarks are embedded in a document. In one implementation the digital watermarks include characteristics that are chosen so that the watermarks will be affected in different manners if the document is subsequently copied or reproduced. A detection method or mechanism reads two or more of the watermarks and compares their characteristics. In another claim, two or more digital watermarks correspond to characteristics that are evaluated for authentication. Of course, other claims are provided as well.

The presently claimed invention relates to image sensors to be worn or attached on a human. One claim recites an apparatus including: an image sensor to capture image data, said apparatus to be worn or attached on a human so that said image sensor captures image data while said apparatus is worn or attached on the human; and an analyzer to analyze captured image data and to determine plural-bit identifiers for one or more objects represented in the captured image data. Of course, additional combinations are provided as claimed as well.
摘要:
A wireless device includes a data capture system, a radiant-energy data transmission system, and a steganographic encoder that hides a plural-bit auxiliary code within data captured by the data capture system prior to its transmission by the data transmission system. An illustrative system, operable with audio input data, is a cell phone that steganographically encodes a user's voice.

The present invention relates to systems and methods for managing images or video and related information. In one embodiment, geographic information system (GIS) layer information is registered or aligned to an image or video using digital watermark information embedded within the image or video. Other embodiments are provided as well.
摘要:
The presently claimed invention relates generally to processing data representing video and audio. One claim recites a method including: obtaining video, the video comprising at least picture portions and audio portions associated with the video; performing a first act of analyzing data representing picture portions of the video or audio portions associated with the video to determine whether the data satisfies first predetermined criteria; and if the data satisfies the first predetermined criteria, performing a second act of analyzing data representing picture portions of the video or audio portions associated with the video to determine whether the data satisfies second predetermined criteria. The first act of analyzing or the second act of analyzing utilizes steganographic decoding. A related claim recites that the first act of analyzing or the second act of analyzing utilizes pattern matching. Another related claim recites that the first act of analyzing or the second act of analyzing derives information from the data representing picture portions of the video. Of course, other claims and combinations are provided as well.
摘要:
Methods for decoding auxiliary control information from audio, and using same to control an audio appliance. Various arrangements are disclosed. One method correlates a filtered version of the audio with predetermined noise data to discern plural bits of hidden data. The data thereby extracted is used to trigger some response in the appliance, such as enabling or disabling certain operations.
摘要:
A multi-aperture interferometric optical system collects light propagating from a source of light and develops overlapping diffraction patterns on an optical detector that produces output signals for processing to automatically focus the optical system and form an image corresponding to the diffraction patterns. A preferred embodiment of the invention is a large aperture orbiting, earth-watching ring interferometric optical system configured such that there is no macro-structure pointing. Four mirror-ring structures direct incoming light to a multi-spectral primary optical detector that acquires light-pattern information to focus the optical system and derive an image.
摘要:
A method of indexing content for network searching comprises obtaining media content signals stored on a computer network; deriving content identifiers from the content signals; using the content identifiers to obtain metadata used to classify the media content signals; and creating a searchable index of the media content signals based on the metadata, wherein users access the searchable index on the distributed computer network to submit a search query for the searchable index to retrieve links to the media content signals.
