NTSC和PAL的区别 

PAL和NTSC，指的是信号的不同的制式。除此之外，另外还有SECAM等制式。
NTSC应该叫正交平衡调幅制，PAL为逐行倒像正交平衡调幅制。现在咱们国家普遍用的是PAL制式。PAL和NTSC制式区别在于节目的彩色编、解码方式和场扫描频率不同。
这个问题比较专业了，好在俺在电视台工作过，呵呵。

    I can’t say much but with my experience through divorce, I had no one until I met hackingsetting50@gmail.com online then I contacted him, surprisingly he helped me hack into my partner's phone and all his social media platforms and i can now access everything and even documented and printed stuffs to show as evidence , now I’m happy with my kids and working for Riches. I hope this helps anyone in need.

    Thanks.
