That is not NTSC. NTSC only defines how to encode colors in a composite
signal. It does not define any resolution or so.
What you mean is the CCIR norm, for the US it is norm M with the color
carrier at about 3.58 MHz, 525 lines with a bandwidth of about 4 MHz (and
*this* is the limiting factor for the horizontal resolution).
might get 640 x 480 with alot of flicker. If you want
color the resolution
went way down due to the way that the NTSC standard handled colors to be
backwards compatible with black and white televisions.
No, not at all. The resolution of the luminance signal was absolutely the
same.
