Basic tuner - ATSC 3.0 to HDMI out

Post by bgpmed »

Hi:
Has there been any thought to creating a simple ATSC 3.0 tuner box with HDMI out? I have not been able to find anything like that.
Since you already have the tuner part, this seems like a great market opportunity for you. As more TV stations go to ATSC 3.0, a lot of people are going to be looking for an inexpensive box they can buy at WalMart, instead of buying a new 65" TV.
Thanks!

You could just use a Raspberry Pi running Kodi mounted behind your TV. Most newer TV's running Android/WebOS support ARC/CEC that allows user to navigate Kodi. If you include HDHR's DVR service you'll have EPG too.

The Raspberry Pi doesn't currently work well with ATSC 3.0. Linux based platforms like the Pi won't get support for key requirements like AC-4 audio or interlaced HEVC until the open source FFmpeg project catches up.

The easiest thing would be to get something that already has built in AC-4 support like the 2019 models of the NVidia Shield or the new Google TV/Chromecast devices and wait for the upcoming updates to the firmware and apps that will fix the audio decoding issues affecting some stations. The Apple TV 4K is also an option, but because of developer restrictions imposed by Apple, it won't support ATSC 3.0's interactive/web functions.

If you're looking for a cheap all in one ATSC 3.0 converter settop box that you can get now, you're out of luck. Like what happened with ATSC 1.0, the first all-in-one set top boxes were very expensive and targeted towards high end early adopters who had HDTV sets that didn't come with ATSC tuners. The more discount boxes for the average consumer didn't come around until several years later. And back in 2009 the cheap converters only had to worry about outputting SD for analog TVs with RF and RCA inputs, this time it's more complicated since any cheap converters will need to output in at least 1080i HD, and still support people who are using TVs that might not have any spare inputs. So converters targetting those types of consumers would need to support HDMI input with an internal switch to pass another device like a BluRay player, DVR, Chromecast or game console and preserve the HDCP handshakes and CEC commands.
