When I interviewed ATSC’s Madeline Noland and Pearl TV’s Anne Schelle a few months ago to see how things were progressing with the NextGen (a.k.a. ATSC 3.0) broadcast system rolling out across the country, I admit to being surprised when I was told “4K is not yet on-the-air.” I wrongly assumed 4K broadcasting was underway in at least a few markets. Not so, though I did learn that high-dynamic range (HDR)-enhanced 1080p broadcasts are happening in some markets.
