  • Publication number: 20050102506
    Abstract: A system for reducing piracy of protected digital content. An integrated module with public and private keys sends the public key along with a request for content to a transaction manager. The transaction manager uses the public key to produce a specially encrypted content bitstream which is sent to the integrated module. The integrated module uses the private key to decrypt the specially encrypted content bitstream to produce analog information that is available for subsequent use. The decrypted content bitstream is physically protected from access. Furthermore, the analog information can be watermarked such that re-digitizing the analog information would produce a traceable watermarked copy of the content.

  • Patent number: 6870331
    Abstract: In a cathode ray tube, plural electron beams are directed towards a faceplate biased at screen potential and are magnetically scanned by a non-self-converging deflection yoke across the faceplate to impinge upon phosphors thereon to produce light depicting an image. The plural electron beams are substantially converged near two opposing edges of the faceplate. A processor changes the raster of the image from a first raster corresponding to position of the image to a second raster corresponding to the position of the plural electron beams on the faceplate. One or more electrodes between the tube neck and the faceplate are biased above and/or below screen potential to deflect electrons landing near the periphery of the faceplate.

  • Patent number: 6771795
    Abstract: A channel is inserted into a sequence of frames for an image, by varying one or more display characteristics of the resulting image across the display. The watermark and other data channel may be employed to watermark the video signal, and the watermark may correspond to the presence of the channel or may be data in accordance with watermark information carried within the channel. For most display devices, display variations are minimized during the design process, but human viewers may still tolerate and accept subtle variations in a displayed image. For exemplary embodiments in accordance with the present invention, slightly changing one or more display characteristics from center-to-side in accordance with watermark information allows for watermarking of the image since viewers may not be aware that display characteristics are changing. For example, a tapering function may be used in a transmitter to vary one or more color components of the video signal representing the image.

  • Patent number: 6687384
    Abstract: A method and apparatus for embedding data in an encoded video bitstream, for example, an MPEG or MPEG-like bitstream, wherein the bitstream includes redundantly coded syntax element values of which one is an overriding value, includes mandatorily coding the syntax element overriding value and replacing the non-overriding syntax element value with the data to be embedded. Apparatus for embedding data in such bitstream includes a coder creating the coded video bitstream with such value mandatorily coded in the overriding syntax element position therein, and a data inserter for inserting the data to be embedded into the non-overriding syntax element position. In an MPEG compressed bitstream, the quantization scale code (QSC) value is mandatorily explicitly coded in the first coded macroblock following a slice header and the embedded data is inserted into the QSC position in the slice header.

  • Patent number: 6563936
    Abstract: A channel is inserted into a sequence of frames for an image, by varying one or more display characteristics across a display in accordance with a spatio-temporal pattern applied to, for example, successive lines of each modified frame. The channel may be employed to watermark the image, and the watermark may be defined as W(x) and its complement [1−W(x)] in counter-phase rotations of successive lines in pairs of frames. The watermark information is applied in relatively still portions of the image with sufficient lightness level. A receiver includes a watermark detector that has a priori information about the watermark. The watermark detector examines specific regions of the displayed image over time, and tests the regions for the watermark during time intervals when the image remains relatively still.

  • Publication number: 20020027612
    Abstract: A channel is inserted into a sequence of frames for an image, by varying one or more display characteristics of the resulting image across the display in accordance with a spatio-temporal pattern applied to, for example, successive lines of each modified frame. In some cases, a reverse of the pattern is applied to a successive frame, and the frames modified are preferably B-frames if the image may be encoded in accordance with an MPEG standard. The channel may be employed to watermark the image, and the watermark may correspond to the presence of the channel or may be data in accordance with watermark information carried within the channel. For most display devices, display variations are minimized during the design process, but human viewers may still tolerate and accept subtle variations in a displayed image.
