    摘要: The disclosure describes methods and apparatus of providing steganographic indicia or digital watermarking in image or video data. One implementation provides a method of embedding a digital watermark in image data captured by an imager, with watermark embedding occurring on-chip with the imager. Another implementation provides a method of managing images. Each of the images comprises plural-bit data steganographically embedded therein in the form of a digital watermark, with the plural-bit data corresponding to a geo-location. Yet another implementation provides a method of identifying locations on a map, with the map being for display via a computer display. Still another implementation provides a method of introducing a watermark message to a watermark embedder located on-chip with an image array. Other implementations and embodiments are provided as well.

    摘要: Digital data is decoded from media signals (e.g., audio, images, video, etc.) using a distributed processing in which a first device receives and pre-processes the signal, and transmits it to a remote device for further decoding. One method pre-filters the media signal, leaving a residual from which digital data is decoded. Other arrangements progressively send portions of the signal for decoding operations.

    摘要: A method of identifying content in a distributed computing system. The method receives an image or audio signal in a first device in the distributed computing system, such as a cell phone or other wireless device. In this device, the method performs an analysis of characteristics of the signal to identify portions of the signal from which to derive a content identifier. The method then sends the portions to a second, remote device in the distributed computing system, such as a server. The server further processes the portions to derive a content identifier, which in turn, is used to look up data corresponding to the content, such as a Uniform Resource Locator. In the case of a wireless telephone network, for example, the method distributes the task of identifying content signals captured through the microphone or camera on the phones in the network.
