=== Fixed-Point Format ===
 
[https://en.m.[wikipedia.org/wiki/:Fixed-point_arithmetic |Fixed-point]] is a method of representing decimal numbers.
Unlike floating-point numbers, fixed-point numbers allocate a specific number of bits for the integer (X) and
fractional (Y) parts of the number, denoted as "X.Y format" (similar to [https://en.m.[wikipedia.org/wiki/:Q_(number_format) |Q-notation]]).
In this format, a certain number of bits are dedicated to the integer part, while the
remaining bits represent the fractional part. For instance, some VI registers employ
the 2.10 format, where two bits are used for the integer part and ten bits are
allocated for the fractional part, resulting in a total of twelve bits.

=== Interlace Mode ===
The NTSC (and PAL) standard support interlace mode which is commonly associated with high resolution, but it can be used for more than that.
