Abstract: An error correction and detection interface between a high speed data channel and a high capacity digital data recording tape system includes a data scrambling and translation scheme which provides an additional layer of error correction to the data as it is recorded. The data scrambling and translation scheme permits the correction of normally uncorrectable large error bursts on digital tape devices.

Abstract: Systems, methods, and processor executable code for high quality wide-range multi-layer image compression of a sequence of video images. A computer-implemented method of adding signal-to-noise improvement layers which are targeted to specific aspects of a sequence of images. The method comprises selecting one or more aspects of a coded image to improve, isolating those image aspects using the selection criteria, and coding a signal-to-noise layer using the isolated coded image aspects. A computer-implemented method for generating a signal-to-noise correction layer from a digitized video image represented as pixels. The method comprises quantizing and dequantizing the digitized video image to create a coded image, subtracting the coded image from the digitized video image to create a signal-to-noise difference image represented as pixels, and applying one or both of quantization weighting and pixel weighting to the signal-to-noise difference image pixel values such that larger difference image pixel values have smaller quantized values.

Abstract: A method and apparatus for image compression using temporal and resolution layering of compressed image frames, and which provides encryption and watermarking capabilities. In particular, layered compression allows a form of modularized decomposition of an image that supports flexible encryption and watermarking techniques. Using layered compression, the base layer and various internal components of the base layer can be used to encrypt a compressed layered movie data stream. By using such a layered subset of the bits, the entire picture stream can be made unrecognizable by encrypting only a small fraction of the bits of the entire stream. A variety of encryption algorithms and strengths can be applied to various portions of the layered stream, including enhancement layers. Encryption algorithms or keys can be changed at each slice boundary as well, to provide greater intertwining of the encryption and the picture stream. Watermarking tracks lost or stolen copies back to the source, so that the nature of the method of theft can be determined and so that those involved in a theft can be identified. Watermarking preferably uses low order bits in certain coefficients in certain frames of a layered compression movie stream to provide reliable identification while being invisible or nearly invisible to the eye. An enhancement layer can also have its own unique identifying watermark structure.

Abstract: A method and system for accurate and precise representation of color for still and moving images, particularly sequences of digitized color images. Spectral and/or extended dynamic range information is retained as images are captured, processed, and presented during color adjustment. Using this extra spectral information, various methodologies for further presenting or processing the color within these images can be optimized. Presentation-device independence is achieved not by attempting to discover a device-independent intermediate representation, but rather by deferring the binding and mapping of color representation onto a presentation device until its actual use.

Abstract: Motion compensation for video compression using a “flowfield” comprising a per-pixel field of motion vectors and confidence values. Flowfields can be quantized transform coded for compression motion compensation. Encoding-only flowfields match with one or more previous and subsequent frames to determine both modulation for resolution-enhancing layers, as well as sharp/soft filtering for an original image, a base layer, and for resolution-enhancing layers. Encoding-only flowfields can be used with various codec types by using the flowfield motion vector length and confidence to drive sharp/soft filters to improve efficiency via in-place noise reduction. Pixels may be displaced using encoding-only flowfields to nearby frames, and weighted for efficient noise reduction. Encoding-only flowfields are discarded after their use in encoding, and therefore do not require coded bits. Encoding-only flowfields can be applied to all frame types, including intra, predicted, forward flowfield-predicted “F” frames, and multiply-predicted “M” frame types, and improve intra coding efficiency.

Abstract: A system and method for bit-exact lossless compression coding of still and moving images. An original image is encoded to produce a lossy compressed image, and is also used to construct a sorted list of bin values to which the lossy image is compared to generate output from which the original image can be losslessly reconstructed. The similarity of corresponding pixel values between the lossy image and the original image permits efficient generation of a lossless residual that allows for bit-exact reproduction of the original image. Pixel values nearly equidistant from two sorted list values are on a “cusp” and either directly coded or flagged as cusp values from which corresponding lossless values can be re-determined. Non-cusp pixel values are coded as the difference between the index of the sorted bin having a value nearest to the floating point value being processed, and the index of the sorted bin containing the exact pixel value of the original image.

Abstract: An image processing system uses a pseudo-random pixel interlace method and apparatus for capturing groups of pixels as image frames. This pseudo-random method eliminates the artifacts commonly present in standard regular line raster scan imaging systems. Moreover, the pixel interlacing method permits the construction of higher resolution frames from a series of orthogonal lower resolution frames. An enhancement circuit deduces information from previous pixel group frames and contributes additional detail to the pixels of the frame being processed. The format of the pixel interlaced groups permits the present invention to be used in a wide variety of normally incompatible target display rates. The present invention can also be used in a computing system as an auto-synchronizer for processing signals from different sources.
