Yes agreed! And while it is not quantized as such there is an element of semi-digital protocol to it. The concept of "scanline" is quantized and there's "protocols" for indicating when a line ends, and a picture ends etc. that the receiver/send needs to agree on... and "colorbursts packets" for line, delay lines and all kinds of clever technique etc. so it is extremely complicated. Many things were necessary to overcome distortion and also to ensure backwards compatibility - first, how do you fit in the color so a monochrome TV can still show it? Later, how do you make it 16:9 and it can still show on a 4:3 TV (which it could!).
