a little expense meaning in English

少量费用

For video codec , after analyzing and researching the newest standard h . 264 , an efficiency algorithm was proposed in this paper using self - feature , spatial correlation and temporal correlation to judge the encoding mode of one macro - block . through this method , the best prediction mode can be obtain before encoding , then , the coding time can be reduced dramatically with a little expense of bit - rate . for video transmission , in this paper , a transmit method was proposed using tcp / ip protocol under the environment of local networks
首先,在分析及研究最新的视频编码标准h . 264的基础上,利用宏块自身的特点和其时间、空间的相关性来判断宏块应该采用的编码模式,从而提前得到该宏块的最佳编码模式,新方法有效地克服了原标准算法中穷举式的复杂算法,在压缩码流只有少许增加的情况下,大幅度地提高了帧内及帧间编码的速度。
