1080p or 1080i?

Post by jachin99 » Mon Oct 07, 2019 7:57 pm

Does the prime broadcast a 1080p signal or does it knock everything down to 1080i. I know each channel will be different but I want to confirm that it's possible to receive a 1080p signal from my prime. Thanks

It is possible as it only passes the bits but it is extremely rare for a 1080p broadcast.

Cable content in the US is almost always 720p60 or 1080i60.

Verizon is doing a few events in 4kp60 which is fun - this is supported by the HDHomeRun PRIME + HDHomeRun app.

1080p60 is supported but we typically only see that in Europe.

Yea, my cable feed can get pretty nasty. Since the prime can do 4k, my any chance would it be compatible with hdr as well?

It simply passes the bits being broadcast... it has "no" concept of what those bits are, whether sd, 720p, 1080i 1080p, or 4k or anything else... i am not aware of any linear broadcasts that have hdr as usually that is with vod content that the prime doesn't do. I think comcast had a few college games in 4k with hdr but not sure if they were a linear channel... most cable systems it is expected that 4k content will be delivered by ip, not linear qam.

After it passes the bits, it is up to a client to render.

That was ALMOST really good news anyway. Thanks for reading my post and explaining things though. Hopefully there will be a atsc 3.0 hdhr tuner and some content to watch within the next few years. I don't even have a 4k set just yet because it's nearly pointless for me at the moment

The HDHomeRun apps will pass 4k HDR content to the hardware decoder on the platform you are using for playback. If the playback device hardware supports 4k HDR then it will work.

Right but I'm not worried about the video player. My main planning concerns are the hardware and lack of content. It seems the primes may not be sent any hdr content (because it will likely be delivered via ip) and the hardware to receive hdr content from the sources most likely to deliver it (atsc 3) hasn't hit the market yet if that makes sense. I want to use a projector but none of those have tv tuners which is why I'm looking to you for the hardware.

ATSC 3 isn't particularly likely to deliver 4K HDR either, at least not for a long time. Broadcasters would be looking at millions of dollars in infrastructure upgrades to handle it, and zero additional revenue generated to pay for it. ATSC 3 first and foremost will be used to deliver more services, and perhaps upgrading the existing SD services carried to HD (many of the existing subchannel networks are actually delivered in HD, and get downconverted to 480i due to bandwidth constraints). 4K is probably going to remain primarily a streaming format for at least the lifetime of any hardware you buy today.

That's also good to know. I'm in one of the markets it is supposed to be rolled out in at some point in the not too distant future so Im glad I made this topic

What will probably happen in your market is that either the otherwise pointless class A repeater of the Fox station will be converted to ATSC 3 and everything else will be left as-is (best solution), or one of the NBC, Fox, and MyTV stations will get all of its services redistributed to the others, and it will convert and probably carry all 3 of those networks in HD and whatever else they decide to put on there.
