1. Friends:

PAL system can be further divided into G, I, D and other systems according to different parameter details, among which PAL-D system is adopted in Chinese mainland. PAL and NTSC are incompatible with each other. If you play an NTSC image on a PAL TV, the picture will become black and white, and vice versa.

2.NTSC:

Each frame of a full-screen image has 525 horizontal lines. These lines are arranged from left to right and from top to bottom. Jump every other line. So every complete frame needs to scan the screen twice: the first scan is odd lines, and the second scan is even lines. It takes about 1/60 seconds to scan the screen every half frame; It takes 1/30 seconds to scan the whole frame.

Extended data

The difference between PAL and NTSC is that movies are played at a speed of 24 frames per second. The video image is 50 fields per second in PAL system and 60 fields per second in NTSC system. Because TV is an interlaced field, it can be roughly considered that PAL system has 25 complete video frames per second and NTSC system has 30 complete video frames.

However, since NTSC has 30 frames per second, it can't directly generate one frame at a time, so 24 movie frames should be converted into 30 video frames through 3-2 pull-down, and the contents of these 30 video frames are equal to those of 24 movie frames, so the playing speed of NTSC is the same as that of movies.
