Intra field coder using irregular approach

摘要

Field of the Invention [0002] The present invention relates to an intra-field coder using an irregular approach which eliminates image deterioration that appears as a flow of a wave appearing in an image by irregularly performing the coding in the field internal enhancement of a digital high definition television Field coding in units of slices or macroblocks, the conventional scheme is to sequentially code from top to bottom or from left to right. In this case, the intra-field coded slice or inter-macro-field coding The image quality deterioration such as a ripple from top to bottom or from left to right due to a difference in encoding method between a slice or a macroblock is displayed. The present invention adopts a random number generator so that a randomly selected slice Or intra-field coding is performed on a macroblock-by-macroblock basis, it is possible to apply the present invention to digital high-definition television and digital television, since it can eliminate the deterioration of the wavy image in the conventional scheme, which is a sequential approach. have.
