File size for the 4K broadcast of Super Bowl LIV?

Thanks for the link.

Are you saying that Channels is going to pick up the 4k TVE feed?

Just to set some expectations for the big game, the Apple TV has had issues rendering the 4K stream direct off the HDHomeRun in the past. So if you want the 4K stream, get the fox sports app ready just in case you have issues.

We haven’t done any optimizations for 4K as it isn’t something that’s been around long.

Is this for the people that are in a FOX O&O area? If there was a national 4K TVE feed, I'd love to record it.

Yeah, just Prime owners.

There won’t be a 4K tve feed. Here’s info on how to watch in 4K:

Thanks for the quick reply.

Sorry for posting incorrectly early today; that's what I get for posting at 5 AM before I go to sleep. When I saw the high channel number of 1498 I thought it was a TVE channel. I was wrong about TVE; if you have a Prime and FIOS TV the 4K broadcast is on 1498.

Is anyone able to successfully transcode off channel 1498? I just tried as a test with the pregame and it seems to be stuck in a loop.

Wonder if our NAS is just not powerful enough to handle 4K transcoding or if something else is wrong.

Guide data for OTA is showing HD HDR?

That’s cool there’s a tag for HDR. The future is finally happening.

The HDR format of the broadcast is HLG which is only supported by TVs and no streaming boxes.

I thought the Fox sports 4k HDR feed is using HLG

Only on the fire tv app. Everything else is SDR. And the broadcast one (cable and satellite) is HLG.

Ok, when it works the HDR on the Fire tv is amazing, but it’s inconsistent.

Same on my Firetv 4k and Apple TV 4K. Haven't been able to watch for more than 5 minutes without it gown down to like a less than hd stream. My Apple TV is hardwired connection to a 1gb fiber. Pathetic.

Is the 4K HDR streaming working for anyone else? The HDR Looks stunning when it works.

I'm watching in on my nVidia Shield - the AppleTV just couldn't handle it. I checked the stream info on my DVR and it's 3840 x 2160 @ 60fps and 20 Mbps HEVC. When using the standard HDHomeRun app it seems to trigger the 10-bit Rec. 2020 mode on the Shield but it doesn't seem to do the same via Channels, but honestly I can't be sure. What I will say, even though it's upscaled 4K, it looks significantly better than the 720p feed that is coming in via my regular Fox channel.

I did check the HDR stream via the Fox Sports app and it was super-washed out - more so that typical HDR and I didn't want to mess with it.

I get the "washed out" look on my AppleTV4k randomly. I find that if I go to settings->video->check hdmi connection that it corrects immediately. I cancel the test and everything is as expected. Must be a bug in AppleTV or my SonyTV as it misses the formatting tags.

Recorded. FOX OTA with HDHR tuners, Nvidia Shield, Channels DVR OK. Great image on playback. No idea of image specs on DF W feed.
Washed out image and hangups on FOX Sports app streaming on 2018 Roku TCL 4K HDR R617. Got HDR notification, but could not watch very long. TV image OK on 4K HDR BlueRay and Amazon Prime streaming on Roku TV channel. Got HDR notification on both media sources.

Can the HDHomeRun even process a 4k input? I assumed anything in or out of the HDHR was 1080p at most.

The HDHR does not care about the stream format at all. It merely passes the bits it receives across the network. It's up to your viewing applications to support the streams being sent by the hardware, not the hardware itself.

FireTV using Fox app was HDR10. HLG was only thru Cable boxes and FuboTV app on Sony Android TV. I don't know of any other TVs that supported HLG with FuboTV App.
