BVU-800P录象机台阶闪烁现象的产生与录象和放象两方面都有关系。录象机放象时产生台阶闪烁现象是由于录象机重放电路中的失落补偿电路误动作所造成的。本文从记录和重放两方面分析了产生台阶闪烁现象的原因,对解决台阶闪烁现象的几种方法进行了分析比较,介绍了一种解决方法——改变失落脉冲形成电路输入滤波网络。笔者认为,最根本的解决办法是做好录象机的维护保养工作。
BVU-800P video recorder flashes the phenomenon of the stage and video and play are related. When the video player to produce the level of flashing phenomenon is due to the video playback circuit in the loss of compensation circuit caused by malfunction. In this paper, the reasons for the step flashing phenomenon are analyzed from two aspects of recording and replaying. Several methods to solve the step flashing phenomenon are analyzed and compared, and one solution to this problem is to change the input filtering network of the lost pulse forming circuit. The author believes that the most fundamental solution is to do a good job VTR maintenance work.
