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.
