zero coefficient meaning in English

零系数

Exp - golomb codes are applied to code the pairs of the run - length of zero coefficients and the nonzero coefficient for lower storage requirement . c2dvlc is a low complexity coder in terms of both computational time and memory requirement
以往视频编码标准如h . 263定义了可选择的算术编码器，新近的h . 264 avc标准也采用了高效的算术编码方法cabac 。
To reduce the runtime of the software , fast algorithms are adopted in the motion estimation and dct modules . moreover , this paper introduces early detection of zero motion vector and all zero coefficients to optimize the coding process
为了提高软件运行速度，对运算时间较长的运动估计和dct模块采用快速算法，并对编码过程进行优化，采用了零运动矢量和零系数提前判决的方法，节省了很大一部分块匹配搜索和dct运算时间。
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编码器的编码速率；对运算量较大的dct给出了快速算法，并对全零dct系数块采用提前判断的方法，从而省去了约40的dct运算，进一步提高了h 263编码器的编码速率。
