摘　　要：通过介绍数码摄像机的磁带记录格式,说明了不同制式机器记录参数的差异,同时利用矢量合成的方法分别计算出PAL和NTSC制数码摄像机(DVC)磁迹与磁带走行方向的夹角,对解决这两种制式数码摄像机彼此播放对方录制磁带的兼容性问题,进行了理论性探讨.This article gives the explanation of the tape format recorded by digital video camcorders, it also describes the difference between sets which has different systems as well. On base of the known parameters, it uses the method of vector synthesis to calculate the angle between tape moving direction and the recording track in PAL and NTSC systems separately, so it is helpful to solve the problem of the capability that a NTSC set can not playback a PAL tape.
