Abstract

PURPOSE:To widely attain the control of an encoding information quantity at respective steps by controlling adaptively the dimention number of a vector in a vector/sub-vector converter and a sub-vector/vector converter and an encoding decoding processing after a second step with an encoding control part for respective steps. CONSTITUTION:A vector/sub-vector converter 4 to form the sub-vector to reduce the dimension number of an input vector from L (=amXbn) ((a), (b), (m) and (n) are natural numbers) to K (mXn), a sub-vector/vector converter 14 to interpolate and reproduce the vector of the dimension number L (=amXbn) with a sample value in the sub-vector of the dimension number K (mXn), and an encoding control part 22 to generate a control signal to switch adaptively the dimension number of the input vector and the sub-vector in accordance with the number of the encoding steps and the encoding decoding processing after the second step are equipped. Consequently, without accompanying the increase in the arithmetic scale of an inner product vector quantizing device, a block size can be made variable. Thus, the control of the encoding information quantity at respective steps can be widely executed.
