Signal Loss - Reboot. Rescan?

Sam

Ahoy.

I am new to the world of DVR, RPi and DVB. I work for a radio station where we use DVB tuners to receive terrestrial TV for our newsroom. We use quite a lot of these for various news sources. We've had loads of issues with our existing DVB tuners, and a large part of this is to do with our RF system throughout our building.
Long term we need to redesign or replace the RF system. That is not a project we can undertake at the moment.

SO I looked at LibreELEC running Kodi with a PVR client (TVHeadEnd) running on a Pi5 with a DVB tuner. I have this working. Sounds great right? No.

Because our RF system is plagued with issues, the RF attenuation across the system drops significanlty causing ALL of our DVB tuners and TV's to drop signal.

This caused the DVB to drop reception. On our existing DVB tuners they generally recover, sometimes not. Our TV's have a high sucsess rate of recover. Our Pi running Kodi? Nope. Drops out and will only recover after a reboot.

Your thoughts and direction is greatly apprecaited.

Sam Your thoughts and direction is greatly apprecaited.

Install a masthead amplifier. Some models can be powered off the RF coax with power injected at the receiver end.
Investigate various USB or IP>Sat tuner options. You did not say exactly which tuner you are using, if it is the RPi hat, then maybe look for something more rugged. There are also 'IP>Sat' tuners that cater for DVB-T.
Look for a legal IPTV source for your FTA channels. Internet delivery would circumvent your RF problems.

Thanks for your thoughts.
To clarify we are using the Pi DVB Hat. We are looking at other options. Balance between cost and reliability.
We do have several IPTV sources for FTA. Unfortunately, the latency that is inherit with IPTV makes it not appropriate for use in our newsroom.

Are you aware of a way to have TVheadend reconnect after reception is lost? If we can automate this process it would be an appropriate solution short term.
