4K is a giant con.

    ATSC is an even bigger con, and it's not even a very funny joke among the electrical engineers who know its origin.

    NTSC = Never Twice the Same Color
    ATSC = Always Twice the Same Color

    ... except when you can't even receive a clean signal from a tower that's a mere twelve miles away from you, then the noise is Never Twice the Same Color in blocky noisy splotches.

    DVB-T2 works so much better, but heaven forbid that the US winds up using a European standard for television ...

    ... like GSM and its evolutions over the years into UMTS and LTE, because obviously that was so horrible for mobile phones as well.

    8K works great over DVB-T2 with adequate bandwidth for it.

    4K over ATSC? It's a total con.

  2. I just don't understand how we can be this many years into this and still not have any content.

    ATSC 3.0 also pushes an IP stack into the ATSC television standard at a terrestrial signaling level ...

    Wikipedia article on ATSC 3.0

    Right now the FCC requires ATSC 3.0 broadcasts to include an ATSC 1.0 simulcast which may or may not operate within the same allocated channel and frequency. ATSC 2.0 (which never deployed) supports ATSC 1.0 backward compatibility, but I'm not sure the same provisions are in place for ATSC 3.0.

    ATSC 1.0 is the version with the crappy signaling specs and blocky Never Twice the Same (Digital) Color, and although ATSC 3.0 potentially fixes this problem with better signaling technologies, it brings along with it a whole range of other problems.

    Are you ready for "Minority Report" TVs and "behavioral advertising"?
