Abstract
In an encoding apparatus for processing a video signal with a signal processing circuit, producing coefficient data by an orthogonal transform of differential data obtained by motion compensation, generating coded data by quantization of the coefficient data and converting the quantization step size at the time of the quantization according to the amount of generated data of the coded data, the signal processing circuit includes: a motion vector detecting circuit for detecting a motion vector of the video signal; a motion code vector amount detecting circuit for calculating the code amount of the motion vector on the basis of the motion vector and for detecting the amount of code of the coefficient data; and a pixel number converting circuit for converting the number of pixels of the video signal according to the amount of code of the motion vector and the amount of code of the coefficient data.
