    摘要: A video signal is converted into compressed frame signals, each comprising 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 extracted from the discrete cosine terms. Each block coefficient signal contains a background component representing a coefficient of the constant term, a linear component representing the coefficients of the polynomial terms, and a nonlinear component representing the coefficients of the discrete cosine terms.

    摘要: 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).

    摘要: Disclosed is a method for generating a high-resolution, real-time, digital video signal from an analog composite video signal such as an NTSC, PAL, or SECAM signal. The analog video signal is digitized and consecutive fields in the signal are merged to produce a frame. Non-uniform interpolation is performed between adjacent scan lines in the frame to generate the high-resolution video signal.
