Have you tried compile from source on possibly a newer version?

Without really looking into it, I dont have much of a clue, on a brighter note though, my install is still running sweet!
Good luck!

So in this case, whit the physical tuner over the same frequency, you can stream for unlimited devices?

for example, can 40 devices see the channel 71 whitout problem?

Hi Federico, Each tuner can handle all the channels on the frequency it is using at the time. For example, Channel 71, 72 and 70 in Australia all use the same frequency. If a user is viewing ch 71, and another user is viewing ch 72, then only the one physical tuner is being used. However is a user is viewing ch 91, and another user is viewing ch 71, then two physical tuners are being used. (91 and 71 are on different frequencies.)
I have 3 tuners to cover the big tv stations in Australia. (7, 9 and 10). However, I really should add one or two more tuners to cover the smaller stations just in case. I hope that makes sense.

David, I think I understand 80% of that! So what I do know is that tzap is part of dvbutils and you’re using this to extract adapter status… Does this deserve its own blog post? hahaha, you don’t want to write for DO by any chance? 😉 On a serious note, what is the main problem this solves for you? Does your signal strength drop often? Are you setting it up to give you a graphical indication that its down?

Hi Dwayne, here’s the solution I found:
1 – create a channel.conf file in zap format, containing the channels/services I want to monitor
2 – for each of the services, run this command (in my case via python subprocess e.g.
tzap -c my_channels.conf -t 5 -x “ABC1”
3 – parse the subprocess.STDOUT to extract the data I want
(frequency, unixtime, FE_HAS_CARRIER, FE_HAS_SIGNAL, FE_HAS_SYNC, FE_HAS_VITERBI, FE_HAS_LOCK, video_pid, audio_pid, signal_strength, signal_to_noise, bit_error_rate, uncorrected_block_errors, FE_REINIT, FE_TIMEDOUT)
4 – save these values to a local SQLite database, so I can see the current status of all the channels, or follow the performance of a specific service over time.
I tried w_scan, dvbv5-scan, dvdb5-zap, dvbtune, but in the end tzap gave me the information required, and was the fastest. Needed to mess about with parsing, hex and binary conversions since it’s not totally human-friendly, but I’m happy with the result.

Hi George, I cannot remember the exact process, but from what I remember you can grab the driver and put it on the Pi. https://www.linuxtv.org/wiki/index.php/Astrometa_DVB-T2 This website lists the Realtek driver as being compatible. Maybe see if you can get a copy of it and install manually on the Pi. Also check this thread out for similar issues, maybe they have a fix: https://tvheadend.org/boards/4/topics/32993

Im using Astrometa DVB T2, problem is “dvb0-frontend1-not-found”, maybe you know what could be the problem?
