@Bigmizzoufan got a chance to briefly dabble with some of the new channels. Some of my first impressions are 1. Slow channel changes compared to atsc 1.0. Takes 5-8sec vs 1sec. Don’t know if this would apply to ATV. 2. AC-4 multi channel audio will need to be considered in a 5/7.1 speaker setup. 3. A few of the channels are not in 1920x1080 resolution like 12xxX720. I think most all of them are 60fps though. This test was at 4am so resolution might change for prime time. It was either channel 4 or 5 that was not 1920x1080. 4. Picture quality seemed slightly better and I think the 60fps will make a nice difference in live sports. 5. Antenna Reception wise I didn’t have time to compare.
Except guide data my earlier problems were related to being remote. I’m going to start a new thread concerning channel load and changing times since we are using different clients. I’ll keep you posted as I have more time and use with 3.0 channels
