Our family watches TV trough IPTV and via streaming services and it's been fine enough for quite some time. However, now one of our broadcast companies got in a fight about streaming contract with our IPTV provider and we lost a few of the channels. Not that big of a deal for me personally, but apparently there's some shows the rest of the family wants to see. This isn't the first time and likely it won't be the last.

However, all the free channels are available over air as well (and that's one excuse for IPTV operators to exclude offerings, "you can watch it anyway"). We have an antenna, but previous house owners just left the cable loose at the outside wall and brough it trough a hole in window frame. I've removed the cable and patched the hole for it and it'd be pretty difficult to run antenna cable to our TV set cleanly. However, I could pull a new cable nearby to my server stack with reasonable effort.

It's been quite a while since I've played with capture cards and any kind of streaming, so maybe hive mind here has some ideas. TV already has Android TV box connected, so anything that works with it is a bonus, but not a requirement.

So, what software (and hardware) I could use to pull video from DVB-T2 and stream that over local network?
