例句與造句

1. 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
   在基于包的無線視頻傳輸中，最佳帶寬分配時，不僅要考慮信源編碼失真，也要考慮由于信道差錯引起的信道失真；已有的宏塊層碼率控制算法以矩陣掃描的順序計算一幀中所有宏塊的量化參數，事實上量化失真與宏塊的編碼順序有很大關系，改變宏塊的編碼順序，使復雜的宏塊分配到更多的比特數，顯然能大大提高編碼效率。
2. It's difficult to find quantization distortion in a sentence. 用quantization distortion造句挺難的
