Abstract
An MPEG2 conforming encoding apparatus and method wherein a control unit adjusts a target number of bits depending on the result of dividing by at least 2 the error between a target number of bits corresponding to the target bit rate and the number of generated bits required for encoding an immediately preceding image segment group, and controls a quantizing parameter for encoding the image segment group in accordance with the adjusted target number of bits.
