quantization distortion meaning in English
量化畸变
量化误差
量子化畸变
量子化失真
Examples
- In packet based wireless video communications , when best band distribution , not only source distortion should be considered , but also channel distortion caused by channel errors . the existing macroblock - layer rate control schemes calculates quantization parameters of all macroblocks ( mb ) in a frame in a raster scan order , and then encodes the mbs in the same order . actually , the quantization distortion is heavily dependent upon the coding order of mbs
在基于包的无线视频传输中，最佳带宽分配时，不仅要考虑信源编码失真，也要考虑由于信道差错引起的信道失真；已有的宏块层码率控制算法以矩阵扫描的顺序计算一帧中所有宏块的量化参数，事实上量化失真与宏块的编码顺序有很大关系，改变宏块的编码顺序，使复杂的宏块分配到更多的比特数，显然能大大提高编码效率。
