摘　　要：高清晰度电视(HDTV)信号传输的基础是高效信源压缩编码技术的实用化。目前不同HDTV系统的视频压缩都采用MPEG-2算法。为检测其运动估值和运动补偿核心算法的性能、测定运动图像各向清晰度等,文中设计并用计算机生成模拟推拉镜头的HDTV变焦序列测试信号。The practice of high - efficiency source compression coding is the basis of the transmission of HDTV signal. Now different HDTV systems all adopt MPEG - 2 algorithm to compress video information. In order to check and measure the core algorithm of its motion prediction and motion compensation, and to determine the all - direction definition of moving pictures, this article design and generate the zoom sequence test signal for HDTV by computer, to simulate the tracking shot.
