A big story from this years CES is the impending roll-out of atsc 3.0. Getting past the usual hype of transitioning from mpeg2 and 8vsb to HEVC and ofdm (digital encoding and rf physical layer) which allows expanded resolution (4k) and sub-channel support, one particular 'feature' that most either skip over or say it will never be used is the capability to encrypt the transmitted stream, turning the atsc 3.0 station into a virtual pay-TV outlet. Avoiding high cable tv fees by putting up an ota antenna? Do so until your local station decides to upgrade to 3.0 and passes on the revenue it gets from cable, satellite, and streaming services to the ota folks. Again, virtually all the commentary I've read says this will never happen, but really, these stations have gotten very used to the revenue stream from the cablecos and others, revenue that was zero until they got the federal law changed in the 90's. I remember when stations were jumping for joy that cable companies came to remote towns and enabled folks to increase their viewership. Then they were sold the idea that doing so was piracy. What do you think it will take to convince them that ota viewers are doing the same thing, stealing their signal without paying for it?
