I was trying to pull up the Cowboys game on channel 4 ATSC 3.0 (104.1 in HD app) and it is not working (no video data). RF 34 only showing like 22% signal strength.

I contacted the station and they're aware of the issue and working on it.

KSTR is back on the air and the HD channels are actually running at the proper framerate for the first time ever. Univision HD is now mapping to 23.4 (123.4 in the HDHomeRun's numbering) instead of 23.1/123.1, and the audio on 4.1/104.1 is just barely there.

Did they happen to say if they were going to fix the audio level?

I mentioned the audio issue on the Fox channel in a reply after they let me know it was back on air, but there hasn't been a response since then.

I am considering buying a HDHomeRun Flex for recording to Plex. I have a 2021 LG OLED TV that has the NextGen TV tuner. I am getting FOX and the info on my TV is saying 1080p. I thought this was supposed to be a 4K signal? BTW, I have no issues with audio.

Not aware of anyone doing 4K. In the future yes, for now this is just testing ATSC 3.

I gotta say... yesterday was the first time I could pull up the ATSC3 version of KDFW on my Apple TV and not have the channel freeze. I was excited! :shock: Yes, the audio was low, but turning up the soundbar, it eventually came in.

Which leads me to ask - is ATSC3 more about the MP4, or the 4K? 4K is attractive, but multiplexing a bunch of MP4 channels on a single transmitter would seem more alluring to me.

The real advantages are the broadcast OFDM (which makes it more resilient to multipath) and the increased efficiency of HEVC as the video codec. 4K OTA may or may not ever happen. It will require a huge investment in infrastructure at the network level, at the distribution level, and at the station level, and it will give them ~$0 of additional revenue. If a widespread move to ATSC 3 ever happens, it's more likely that it will look about like what it does now, except a step up. Instead of stations carrying the main network feed at 1080i or 720p and a bunch of subchannels at 480i, we'll see the main network at 1080p and a bunch of 720p subchannels. 95% of people don't sit close enough to their TVs to see the difference between 1080p and 4K anyway.
