I'm not nearly as versed in this subject as many of you so I thought I'd ask this here (though I'm not entirely sure this is the right place either).
I'm trying to replicate the viewing experience of old analog NTSC television, at least as best as one reasonably can in 2020. As I understand it, an NTSC composite video signal was transmitted in AM using a vestigial sideband. Chroma was transmitted in QAM and audio was transmitted in FM, often with multiple sound channels. These signals would then be demodulated by the TV.
What I'd like to know is how this degraded the already poor composite video signal, if it did at all, and how this form of modulation might compare in terms of video/sound quality to a home RF modulator you could buy online today for an affordable price, or one you might get in a VCR, DVD player, video game console, etc.?
Any help would be greatly appreciated.
