> Worry about marketing once you have something to market.
After years of research and experimentation, I have written a spatiotemporal comb filter for NTSC TV signals which consistently outperforms the state of the art.
It's done. I use it for digitally archiving Laserdiscs.
Does it solve a problem / meet a demand in a significant fashion? If so, ask the right people and ye shall receive. I don't know anything about marketing.
For context, the other user alludes that building their dream project is trivial. I take this to mean it should be pursued regardless of how well the marketing outcome would be. If it's paramount that something sell well (because of upfront cost, time, preference, etc) then it's worth scrutinizing whether it can sell.

I think you slightly late, at least for Laserdiscs - they are gone to history, now all new video already digital from beginning.
Few years ago in 3rd world, was popular to make business for digitally archiving old analog home archives. Scheme was simple - just rent cup of square meters in some crowded place and gather clients.
If it could fit other cases, business schemes could be very different, depend on case.

How can I market this?
