位率又称为“码率”。指单位时间内,单个录像通道所产生的数据量,其单位通常是bps、Kbps或Mbps。可以根据录像的时间与位率估算出一定时间内的录像文件大小。
该方法能有效地消除图象数据的空间相关性,获得低传输位率。
This method can efficiently remove correlation in image data, obtaining a low transmission bit stream.
为了得到可变的位率,在分形图像压缩中经常采用四叉树分割方法。
Quadtree partitions are often used in fractal image compression to achieve variable bit rates.
该策略以视频的长度和位率为参数,增加了请求的获准率,同时降低了获准延迟。
This strategy has the length and bit rate of the video as its parameters, increasing the admission ratio and decreasing the admission delay.
