摘要:
A portable device for use with audio or visual content (e.g., an MP3 player-like device, or a camera-enabled device) is equipped with one or more features/capabilities, including: a user interface through which a consumer can instruct that content be delivered to a different consumer's device, the ability to derive identifiers from content and take action(s) based thereon, the ability to count playbacks of content; and/or the ability to interact with remote web services. A variety of other features and arrangements are also detailed.

The disclosure describes a method of connecting multimedia content to a network resource. This method operates in a computer network environment. Operating in a network connected device, the method extracts an identifier from a media signal, such as from a digital watermark, perceptual hash, or other machine extracted signal identifier. It then sends the identifier to a network along with context information indicating device type information. From the network, the method receives related data associated with the media signal via the identifier. The related data is adapted to the network connected device based on the device type information. This device type information may include a display type, so that the related date may be formatted for rendering on the display type of the device. This device type information may also include a connection speed so that the related data may be optimized for the connection speed of the device.
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.

The present invention relates to steganographic systems and methods. One claim recites an apparatus including: electronic memory to buffer a compressed digital watermark object, the digital watermark object is a separate object relative to a compressed video object; and an electronic processor. The electronic processor is programmed for: decompressing the compressed video object to yield a decompressed video object, the decompressed video object comprising data representing video picture elements and data representing audio elements; decompressing the digital watermark object to obtain digital watermark data; steganographically hiding the digital watermark data in the data representing video picture elements or in the data representing audio elements to yield digital watermarked video or audio; and rendering the digital watermarked video or audio. Other claims and combinations are provided too.

The present invention relates to steganographic systems and methods. Once claim recites a method including: obtaining video content, wherein the video content comprises a steganographic signal embedded in picture elements of the video content, with multiple instances of the steganographic signal embedded in the picture elements of the video content, the steganographic signal comprising a plural-bit identifier that is uniquely associated with an intended recipient of the video content; encrypting—utilizing a processor or electronic processing circuitry—the video content with an encryption key that comprises mathematical relationship to the plural-bit identifier that is uniquely associated with the intended recipient of the video content; obtaining a decryption key that comprises a cryptographic relationship to the encryption key; communicating the encrypted video content and the decryption key to the intended user of the video content; and maintaining an association of the plural-bit identifier with the intended recipient. Other claims and combinations are provided as well.
摘要:
This application relates, e.g., to processing video and audio. One claim recites a method including: utilizing a multi-purpose electronic processor programmed for analyzing a video signal to derive or calculate an identifier from data representing picture elements of the video signal or from data representing audio accompanying the video signal; providing the identifier to memory or to a remote repository to obtain advertizing information; receiving advertizing information from the memory or the remote repository; and controlling rendering of the advertizing information such that the advertizing information is synchronized with at least a portion of the video signal when rendered. Of course, additional claims and combinations are provided.

Embedded data in gaming objects is used to authenticate the gaming object and to enhance the gaming experience in gambling venues The gaming object is authenticated automatically using information about the venue encoded in the gaming objects. The behavior of electronic gambling game systems is enhanced by extracting covert data from gaming objects and using the extracted data to control behavior of the gambling game.

摘要:
Media objects are transformed into active, connected objects via identifiers embedded into them or their containers. In the context of a user's playback experience, a decoding process extracts the identifier from a media object and possibly additional context information and forwards it to a server. The server, in turn, maps the identifier to an action, such as returning metadata, re-directing the request to one or more other servers, requesting information from another server to identify the media object, etc. The linking process applies to broadcast objects as well as objects transmitted over networks in streaming and compressed file formats.

This disclosure describes several video watermarking and fingerprinting enhancements. These enhancements include synchronizing watermark detectors with one-dimensional calibration signals, layering digital watermarks, watermarks for version control, compressed domain watermarking, watermarking of video object layers, key channel watermark embedding for video, robust fingerprinting of video and watermarking of scalable video.
