I am experiencing a great amount of continuity errors with Tvheadend on my newly purchased Vero 4K+, with the original DVB-T2 TV dongle. This can be seen as artifacts while playing a TV channel.
Shortly after reboot there are no errors, but after about half an hour they begin to accumulate more and more. Both SD and HD channels are affected. Tvheadend is installed from OSMC App store, Tvheadend HTSP Client is used as a PVR client.
Tvheadend logs obtained with journalctl -u tvheadend:
No, I have a desktop PC with Debian Stretch installed, and it will be some effort to move it closer to the TV cable, and there is also a MacBook, but I doubt if macOS is a good choice for testing. If it is important to know how the dongle behaves on another device, I’ll give it a try.
I’ve noticed one more thing: in the beginning the signal strength is at about 80 dBm, but just before the first continuity error it suddenly drops to 45 dBm. The same with SNR, which jumps from 20 dB to 35-40 dB.
Maybe, but the signal starts dropping/jumping just 25-30 minutes after reboot, so it is rather related to the device, not cable or aerial. And when plugged directly into the TV set (with built-in tuner), there are no problems.
