Abstract
If the number of frames in a GOP of an input stream is not less than 15, the GOP is determined as a control unit time. If the number of frames in the GOP is less than 15, the following GOP is connected thereto until the number of frames becomes not less than 15 and the connected GOPs are determined as a control unit time. After correcting the control unit time, the average input bit rate Sin each control unit time is obtained, and by using information on the input stream including the average input bit rate S, a quantization step value of an output stream is calculated.
