Remote controls aftermarket/legacy/grey market

A bit more

"rm series" "remote control" in google shows there is a generic physical form of 40 keys or higher keypad counts and within them subsets with differing legends for DVD/TV etc , for hundreds of different makes and models within those subsets. Just the data must be different inside and a different RMC number. Not all functions are necessarily present eg my one has no PiP function that is on the original r/c but never used anyway, but it does have the vital Menu and Enter key. What an enterprising idea on someone's part. I just wonder what lies behind the data accumulation/distribution, part of the dark web? If they pulled the data off "universal " r/c s then it was not on one of the 5 or 6 "universals" that I tried. A market stall near me has a few boxes of hundreds of assorted used r/cs for 1 or 2 quid each. Perhaps something like that or a large charity shop that gets hundreds of donated units with remotes , but are not sellable, is the source of the data. But usually like that only the maker name is there , not the unit model number that those r/cs relate to
