ATSC3.0 Broadcast and AC-4 Sound

If they’re going to be this annoying about adding ATSC 3.0 support, why not just make it included with plex pass or something. This is just taking way too long. Unacceptable!

I really don’t want to pay for Emby just to try the live tv. Please PLEX.

I found, living in Columbia, I get a lot of channel breakup and pixillation with 1.0 that I don’t get with 3.0 but then again no sound. So, I’m back to 1.0 for now.

@Dadrepus Can Plex not even transcode the AC-4 sound to AC-3?

Not when I tried it. It just said unknown audio and would not transcode, unless I didn’t know what box to check or something.

That sucks! Thanks for the quick reply.

You don’t need to “pay for Emby to try the live tv”. Live TV from 3.0 signal works fine with HDHR’s player.
But your comment seems to imply that you think this is more than what it is. As noted by aaronwt just a few posts before yours, “the quality is basically the same as their ATSC 1.0 counterpart”. You should not be excited or feel like you somehow missing out on something as you aren’t. You will just be very disappointed if you have those expectations, get it, and then realize that it essentially the same image as 1.0. Until 4k end-to-end images start getting broadcast (could be years from now), and/or good HDR, there isn’t anything to get worked up about.

You are correct that aaronwt said that ATSC 3 will not help him, many others, including myself, have noted a huge quality improvement with the new format. Mainly because of weak signal strength, and improvements built into the 3.0 signal. Most here asking for this to be completed are not asking because they want 4k, it is so we can watch OTA channels at all.

In Denver, the 3.0 channels are in 4k with Dolby Digital 5.1 sound vs 1080 stereo feeds on 1.0. The current plex TV guide doesn’t have entries for the 3.0 channels, so I can’t watch or record them in Plex.

I’d like to see this resolved. The better picture and sound have me using the HDHomeRun app wen I watch OTA.

You need to select the 3.0 channel and map it to the ATSC 1.0 channel. So it gets the guide info from the 1.0 channel listing. You just need to make sure you disable that ATSC 1.0 channel in the list first. Since you can’t map the same channel to more than one location.

Of course, even if you do this you will not get audio from the 3.0 channels. Since Plex can’t handle the Dolby AC-4 audio that ATSC 3.0 uses yet.

I have been mapping the ATSC1 channel to the main ie 24.1, and the ATSC3 channel to to 24.2. That way they show up next to each other on the guide, and are both available to watch. Just know that the guide for the 3.0 channel is wrong (:

There might be a minor improvement, depending on how your TV handles the signal, but again, the source is the same in every market. Your TV might handle the 1080p signal better than the 1080i, or there could be some other reason for a perceived improvement, but it would be a minor change (and likely still less quality that what people get from the same shows via streaming service). As for reception, the technology does allow for some edge cases to overcome reception issues, such as if you have trees that partially block your antenna or you have some buildings that give you multi-path. But for most it won’t make a difference as it can’t be received from further away.
In the majority case that I’ve seen, when we’ve looked at what channels were problematic for 1.0 that are good for 3.0, the reason was because the lighthouse where all 3.0 signals were being broadcast from currently, was closer to the person than the antennas where the 1.0 signal was broadcast from. While that is great for those people for now, once the 1.0 signals drop in a few years, the problem will reemerge when stations move the 3.0 signals back to their primary towers.

Any update from Plex on this issue?

Is there any actual official announcement from the Plex team about ATSC 3.0? Regardless, add my name to the growing list of users who need ATSC 3.0 support!

TBF, ATSC 3.0 is a hot mess. Even the fact that the broadcasters will send 3.0 signals with encryption adds further reason to just wait another year. It’s a hot mess. You all want to jump on the 3.0 band wagon but the fact that much of the ins and outs are still haven’t been solidified yet. Good luck to you all. I’m sitting out on this for another year until this nonsense gets straightened out. Yes, Plex should have had some things taken care of but Plex still has to rely on manufacturers of these tuners to send continuous updates until this all irons out. They should at least continue to make the dvr and epg guide elements as solid as possible so when 3.0 does get implemented properly, it all works.

That’s gross. There should be poison pills associated with these spectrum grants - play stupid games, lose the allocation. The spectrum is valuable, and the social contract was for open access.

That includes the idea of encrypted premium sub-channels. We gave out huge swaths of spectrum back when it was necessary and when a “channel” was a very different thing from today. Today’s megacorps shouldn’t be allowed to divert spectrum for profit.

I respect that but the fact is the format of the signal has been set for some time now:
HEVC 10bit for the video and AC-4 for the sound. plex already supports the video part of that and just needs to close the deal with Dolby and incorporate the Dolby provided code into there servers to transcode into something the client can play.

What happens with DRM or 4K etc. is something the tuner people need to handle not plex. What ever way the broadcasters go has little to do with plex they simply need to handle the AC-4 sound. plex has never dealt with DRM nor stated they will.

If they plan on charging for these channels, they might as well package the signals both as OTA 3.0 signals and have a streaming platform for IPTV that’s localized per market. Have interested households pay a license fee like the UK do for the BBC television licenses. It makes no sense to try to make money off of those channels if not everyone is able to have a proper antenna setup.
