zero computing time 中文意思是什麼
zero computing time
解釋
計算開始時間-
With a view to dct that costs the longer computing time, fast dct is proposed, and the method of prejudgment of an macro - block of all zero coefficient of dct is adopted in this paper, which makes about 40 percent dct computation reduced, consequently, the encoding speed of h. 263 encoder can be further increased
263編碼器的編碼速率；對運算量較大的dct給出了快速演算法，並對全零dct系數塊採用提前判斷的方法，從而省去了約40的dct運算，進一步提高了h 263編碼器的編碼速率。
