But, a new major update of ffmpeg just came out, and AC4 decoding was nowhere to be seen, so I am not holding my breath on that one. If ffmpeg ever supports AC4 decoding (there is a forked version out there that supposedly does but getting it installed may be beyond the capability of most users), you could run the output of the HD Homerun into a computer running Tvheadend and then pipe the audio through ffmpeg to decode it to AC3.

If your TV or receiver can decode Dolby Atmos then I think it will be able to decode the AC4 audio without the need for transcoding but unless you have fairly new equipment it probably won't have Dolby Atmos built in. But still, I'd much rather have the audio transcoding built into the HDHomerun device itself as opposed to relying on some cloud-based service and a possibly flaky (especially during prime time) internet connection.

The real reason they want to go to ATSC 3.0 is to target advertising based on your location and viewing habits. If you thought it was to give you a better TV signal, silly you, that's just the carrot they are using to get people to upgrade. If you don't like Dish Network or DirecTV or your local cable company because they track what you watch, now this device may be doing the same.Īlthough that said, part of the whole point of ATSC 3.0 was so broadcasters could know where you are and what you are watching. But the bigger issue is that if they are sending the audio to be transcoded, what else are they sending? Maybe they are building a nice record of your viewing habits? In theory they could know every channel you tuned to, and when and how long you were tuned to it.
Of course the implications of that are that if your internet connection goes down you lose the ability to watch TV, or if the network is congested and the round trip for the audio takes a while you could be several seconds behind everyone else. Instead, Silicon Dust (makers of the HD Homeruns) is apparently offering some kind of cloud-based transcoding service that will (in theory transparently to the user) transcode the AC4 audio. If and when the new ATSC 3. When it comes to TV antennas, some may reference 4K or HDR support in marketing materials, but in reality, theres no such thing as a 4K antenna. Just beware that the Hd Homerun 4k Flex is unable to natively transcode AC4 audio (the format inexplicably used by many ATSC 3.0 broadcasters) to the more standard AC3 that most TV sets can decode. ATSC 3.0, otherwise known as NextGen TV, is a whole new way of delivering free, broadcast TV over the air (OTA), and 2020 will be the year most Americans can get their first taste of the new. The maximum resolution youll be able to get Over-the-Air today is 1080i or 720p, and the best sound quality would be Dolby 5.1 audio.
