FIELD: physics, computer engineering.SUBSTANCE: invention relates to computer engineering. A video coding control method for controlling input video signal coding, which includes detecting decoder buffer underflow; if decoder buffer underflow is detected, calculating the period of time for reducing the size of the generated code based on a predetermined threshold value for the filling rate in the decoder buffer and data transmission rate when coding; and performing control for continuous reduction of the size of the code generated for each coded target image during the calculated period of time, by passing the coded target image or by coding the coded target image to form a minimum size of the generated code.EFFECT: improved image quality.4 cl, 8 dwg |
