I've had that but the other way round. I did have the equipment to transfer a NTSC tape over to UK PAL system though :-) The difference is the fact that NTSC has 425 scanning lines whereas PAL uses 625 (I think I have those figures correct but they are from memory) The new HD format will be universal :-) NTSC is 525 lines
Where do you get that? Pal is 720x576 and NTSC is 720x480, both in the traditional 4x3 format. widescreen has changed it a little, but I don't see 525 anywhere
There is something called NTSC/525, but in that there are only 480 lines of video, and the rest is used to transmit extra data
In both NTSC and PAL &SECAM. The number refers to the total number of horizontal lines per frame, including the superblack sync bar. For NTSC, that number is 525 and it's 625 for PAL & SECAM. NTSC has had 525 lines, since before WW2. These numbers predate personal computers by many years. Also, NTSC is 60 fields/second or 30 frams/sec. PAL & SECAM are 50 fields and 25 frames.
