CODING METHOD AND CODING APPARATUS |
摘要 |
A coding method and apparatus for coding a digital video signal of interlaced type. Three-dimensional (horizontal, vertical and temporal directions) blocks are constructed for every plurality of picture elements, orthogonal transform is performed to each of the three-dimensional blocks and coefficients area coded. Coefficients non-effected by pseudo-moving part are performed weighting with low rate, and coefficients effected by pseudo-moving part are performed weighting with high rate. After the vertical positions of picture elements of odd-number fields and those of even-number fields are coincided with each other by intra-field picture elements operation, the digital video signal is formatted and three-dimensional orthogonal transform is performed. <IMAGE> |
