Abstract
A method and apparatus can determine the VBV delay from the bit rate without limiting the encoding time and raising the cost. An image compression-coding apparatus adapted to control the volume of generated codes on the basis of the occupied volume of the VBV buffer at the decoder side comprises an MPEG encoder for computationally determining the cumulative value of the number of input bits of each frame and output as volume of generated information, a number of input bits generating section for computationally determining the theoretical value of the number of input bits from the bit rate, a B(n) counter for replacing the value of the volume of generated information by the theoretical value at the end of a number of frames when the theoretical value of the number of input bits becomes equal to an integer and a VBV delay computing section for computationally determining the VBV delay on the basis of the occupied volume of the VBV buffer from the B(n) counter
