  • Patent number: 6069919
    Abstract: A method of low-delay-encoding digital video data for moving pictures, comprises the steps of determining a first row position of first intra-segments in an image frame and a second row position of second intra-segments therein, with respect to odd-numbered first intra-segments and even-numbered second intra--segments having a respectively predetermined size which are interposed between each other when the first and second intra-segments are disposed in the row direction on a screen and are placed in the same row axis, intra-frame-encoding video data contained in the first and second intra-segments among the video data in the image frame, inter-frame-encoding video data which exists outside of the first and second intra-segments, and re-determining row positions of the first and second intra-segments with respect lo the image frame to be used for encoding, by shifting the first row position of the first intra-segments from the upper end of the screen to the lower end thereof by a predetermined interval, and t

  • Patent number: 5793897
    Abstract: An adaptive variable-length coding/decoding method performs an optimal variable-length coding and decoding depending on an intra mode/inter mode condition, quantization step size and a current zigzag scanning position, such that a plurality of variable-length coding tables having different patterns of a regular region and an escape region according to statistical characteristics of the run level data are set. One of the variable-length coding tables is selected according to mode, quantization step size and scanning position, and the orthogonal transform coefficients according to the selected variable-length coding table are variable-length-coded.

  • Patent number: 5745180
    Abstract: A method and apparatus for low-delay-encoding digital video data for moving pictures. For removing artifacts appearing on a screen, where there is a large amount of motion in a vertical direction, a modified intra-slice method is used. Similarly, for removing artifacts appearing on a screen, where there is a large amount of motion in a horizontal direction, a modified intra-column method is used. For both the modified intra-slice method and the modified intra-column method, first and second rows of hatched rectangles, called intra-segments, are used to determine where in a given frame intra-frame-encoding is to be performed. Regions outside of these intra-segments are inter-frame encoded. However, while the intra-segments are disposed in a horizontal direction for the intra-slice method, they are disposed in a vertical direction for the intra-column method. Both of these methods can be performed simultaneously, as well.
