Abstract
A video encoding control method for controlling encoding of an input video signal. The method includes the steps of detecting an underflow of a decoder buffer; if the underflow of the decoder buffer has been detected, suppressing an amount of generated code by skipping an encoding target picture or by encoding the encoding target picture so as to produce a minimum amount of generated code; after suppressing the amount of generated code, comparing a current rate of occupancy in the decoder buffer with a predetermined threshold for the rate of occupancy in the decoder buffer; and performing a control for continuously suppressing the amount of code generated for each encoding target image by using the above step of suppressing the amount of generated code until the rate of occupancy in the decoder buffer exceeds the threshold based on a result of the above comparison.
