Abstract

A hybrid Discrete Cosine Transform (DCT) coder processes blocks of (e.g., 8.times.8) pixels from interlaced or progressive scanned image signals. Processing of image lines by the coder is modified in the presence of image motion to avoid switching between 8.times.8 and 2.times.(4.times.8) transformations. For motion, the lines of two vertically superimposed image blocks are rearranged to produce first and second modified blocks. The modified first block contains pixels from lines in a first field, and the modified second block contains pixels from lines in an associated adjacent second field.
