Abstract
A coding apparatus includes a large block forming unit for forming a large block of sample values of an input signal, a small block forming unit for dividing the large block into a plurality of small blocks, a first coding unit for coding the small blocks of the input signal by using a difference signal obtained by subtracting a predicted value from the small blocks of the input signal, a second coding unit for coding the small blocks of the input signal without using the difference signal, and a selecting unit for selecting the first or second coding unit in units of large blocks.
