Abstract
A coding controller takes a buffer occupancy at present from a transmission buffer, and a first normalized value evaluating device outputs a first normalized value, independent of a video rate. A frame rate for the number of bits per block (n.times.QB) is determined and a second normalized value evaluating device outputs a second normalized value for the number of bits per one frame. When the number of bits is relatively small, a second quantization characteristics control table is selected in a selector and the coding control is performed every frame. When the number of bits is large, a first quantization characteristics control table is selected in the selector and the control is performed every block (n.times.QB), instead of the control every frame. The quantization characteristics control signal is then outputted.
