  • Patent number: 5831872
    Abstract: A video signal is converted into a coefficient signal for each frame in a video image. Each coefficient signal comprises block coefficient signals which represent the pixels in a pixel map block (420) in a pixel map (410) with the coefficients in a hybrid polynomial. The coefficient signal for only selected frames is transmitted to a receiving computer (130). The coefficient signals are selected based on a number of coefficients in the coefficient signal for a current frame that vary from corresponding coefficients in the coefficient signal for a sequentially previous frame.

  • Patent number: 5793892
    Abstract: A pixel map signal is converted into a coefficient signal of block coefficient signals, each representing the pixels in a pixel map block (420) in a pixel map (410) with the coefficients in a hybrid polynomial. The coefficient signal is quantized by dividing each of the coefficient values in each of the block coefficient signals by quantization factors to produce quantized coefficient values which replace the coefficient values. Block coefficient signals which represent an edge block (424) in the pixel map (410) are divided by larger quantization factors than block coefficient signals which represent a center block (422) in the pixel map (410). As a result, smaller quantized coefficient values are obtained so that block coefficient signals which represent an edge block (424) are compressed to a greater extent than block coefficient signals that represent a center block (422) in the pixel map (410).

  • Patent number: 5768427
    Abstract: A video signal is converted into a coefficient signal of block coefficient signals for each frame in a video image. Each of the block coefficient signals represents the pixels in a pixel map block (420) with the coefficients in a hybrid polynomial. The hybrid polynomial contains discrete cosine terms, a constant term separated from the discrete cosine terms, and polynomial terms separated from the discrete cosine terms. Coefficient signals for selected frames only are transmitted to a receiving computer (130). The coefficient signals for the selected frames are converted to decompressed pixel map signals and the pixel map signals for unselected frames are interpolated using nonlinear interpolation. The decompressed pixel map signals and interpolated pixel map signals are ordered into an original frame sequence to produce a decompressed video signal.

  • Patent number: 5752012
    Abstract: A computational array includes a self timed computational element that performs self timed calculations internally independent of a global clock. The self timed computational element includes a computational unit (100) which produces a complete signal upon the completion of calculation of a result value. The self timed computational element also includes a self timed control unit (200) which determines whether a new result value is to be calculated by the computational unit (100) based on an iteration signal which indicates a number of times the new result value is to be calculated, and based on the complete signal received from the computational unit (100) indicating that each previous calculation has been completed. Upon determining that a new result value is to be calculated, the self timed control unit (200) provides a self timed clock signal to the computational unit (100) and the computational unit (100) calculates the new result value accordingly.

  • Patent number: 5727084
    Abstract: A pixel map signal is separated into block signals, each representing pixels in a pixel map block (420) in a pixel map (410). The blocks signals each contain an overlap component having pixel values representing pixels contained both by the corresponding pixel map block (420) and an adjacent block. The pixel map signal is compressed by converting the block signals into a coefficient signal of block coefficient signals, each of which represents a pixel map block (420) with the coefficients in a hybrid polynomial. When the pixel map signal is decompressed, the pixel values in the overlap component for each pixel map block (420) are averaged with the pixel values in the overlap component for the adjacent block and replaced by the averaged pixel values in the corresponding pixel map block (420) and the adjacent pixel map block (420).

  • Patent number: 5696875
    Abstract: A speech signal is sampled to form a sequence of speech data. The sequence of speech data is segmented into overlapping segments. Speech coefficients are generated by fitting each segment to a nonlinear predictive coding equation. The nonlinear predictive coding equation includes a linear predictive coding equation with linear terms, and additionally includes at least one cross term that is proportional to a product of two or more of the linear terms. If the segment is voiced, a sinusoidal term is included in the nonlinear predictive coding equation and sinusoidal parameters are generated. Otherwise, a noise term is included in the nonlinear predictive coding equation. The speech coefficients, a voiced bit, and, if the segment is voiced, the sinusoidal parameters are included as compressed speech data.

  • Patent number: 5613106
    Abstract: A transaction, consisting of a compilation of changes made to one or more data objects of a database, is transfered to a primary transaction engine of a primary database for processing. A copy of the transaction is sent by the primary transaction engine to a shadow transaction engine of a mirror database for processing in the local store. The transactions are then processed by the respective transaction engines. If the transaction is successfully processed by both transaction engines, the respective databases are updated from the local data store. If one of the transactions is not successfully processed, the system takes corrective action and optionally notifies the user.
