People under 25, how many of you are aware that you can get 1080p HD TV programming (and many live sports) for free over the air with no app sign-in or susbscription fee? (lemmy.world)

Multicast is a thing, though it doesn't seem to be widespread. That would make a lot more sense than this weird DRM broadcast system.

Multicast still requires more expensive less widespread bandwidth than sending out analog signals ota & shooting off a few packets of encryption information every now and then. US infrastructure has rapidly improved over the past few years, but we're still a farcry from anything robust and reliable enough to serve the people benefiting from this type of content.
