摘要： 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 Sn in each control unit time is obtained, and by using information on the input stream including the average input bit rate Sn, a quantization step value of an output stream is calculated.

摘要： In a transmission device, an image signal and an audio signal are played back at a speed n times normal speed from a recording medium and the played back image signal is encoded. The played back audio signal is sampled using a sampling clock signal of a sampling frequency which is proportional to the speed n times normal speed. When n>1, 1/n items of sampling data of the sampling data generated by sampling is encoded. When n

摘要： A quantization step determination part inputs an evaluation value (ACT_MB) indicating the dispersion in a macroblock and its average value (ACT_PIC). A subtracter obtains the difference between these values, and a multiplier multiplies the difference by raq ( 1) to obtain a converted quantization step value (Qstep_AVC). This optimizes a bit allocation in accordance with an Activity value of the macroblock, to thereby improve the quality of image.
