So the chapter introduces the compressed domain transcoding technologies , including dct - domain image down - conversion ( i n case of the simple conversion ratio ) , dct - domain motion - compensation and inverse motion - compensation
针对第二类转码，本文第三章主要研究mpeg - 2到mpeg - 4压缩视频流转码。
And the retrieval algorithms of mismatched macroblock for dct - domain requantization trancoder are introduced in the chapter . many simulation results testified that the motion - compensation only for p - pictures transcoding solution is a better compromise between the complexity and video quality
大量仿真结果证实，本文提出的省略b帧运动补偿转码器是视频质量和运算复杂度的一种较好的折衷算法。
