PAL generates 25 full frames per second with 635 lines per frame while NTSC produces 30 frames a second with 525 scan lines per frame. Due to screen interlacing (in which all the odd lines and then all the even lines of the frame are presented), the vertical scan frequencies for PAL are 50Hz (50 scans per second) and 60Hz for NTSC. This basically means that the NTSC system sacrifices video clarity to minimize flicker, while PAL accepts more flicker to gain an improvement in clarity. A PAL signal can not be replayed on an NTSC TV or Video, and conversely an NTSC signal can not be replayed on a PAL TV or Video. However many current TVs and Video Players are
