DVB-T2 ZDF Mux in Leipzig/Germany at 482MHz not working

Hello, I use DVB-T2 with tvheadend server on my Raspberry Pi3 B (Kodi 18 - libreelec 9.2.6). I got all public channels working but ZDF, 3Sat and arte. These...

Hallo Tobias,

That’s good that you got it working, nothing appeared for me at all even with the aerial pointing at the Colonius tower out of the window, the ARD works perfectly, including receiving the separate version of the WDR mux from Düsseldorf/Rheinturm in addition.

I would be very interested in a full MPEG-TS dump of the ZDF mux if you would be able to provide one? I’m curious to see if anything is different with the configuration which causes some tuners to fail. Thank you.

Kind regards,
Adam

Hallo Adam,

maybe I can do it, if you tell me what a MPEG-TS dump is. But remember that I'm on a raspberry pi4. So maybe it's not so easy.

Yesterday I updated libreelec on version 10. I feel as the DVB-T2 works better. Bevor that, there were some stoppings in the sound. And when I watched soccer in the afternoon, shortly pictures of the game were seen when I watched news in the evening. Now these disturbtions vanished, as I think. My TVheadend Server is now version 4.2.8-32.

For you I made a short test with some unfavor positions of the antenna. The signal is now really stable. And in a worse position ARD still works, but ZDF not.

My stick is a Haupage WinTV soloHD. And it is a Kernel version 5.

To make a full multiplex MPEG-TS dump, all you should need to do is go into the TVHeadend web admin, and go to Configuration > DVB Inputs > Muxes

Then, copy the URL from the play button for the 482MHz ZDF mux. It'll look something like -

http://192.168.1.2:9981/play/ticket/stream/mux/0123456789abcdef0123456789abcdef?title=482MHz%20%2F%20Network%20Name

Remove the question mark and everything afterwards, and also /play/ticket, then in your Terminal in Linux or Powershell in Windows, run the following, with the example URL from above modified -

wget http://192.168.1.2:9981/stream/mux/0123456789abcdef0123456789abcdef -O zdf_dvbt2_482mhz.ts

If you're using a username/password, you would maybe need to do -

wget --user user --password pass http://192.168.1.2:9981/stream/mux/0123456789abcdef0123456789abcdef -O zdf_dvbt2_482mhz.ts

This will start dumping the full multiplex to a TS file. Let this run for something like 30 seconds, then hit Ctrl+C to stop it. You should then have a file called zdf_dvbt2_482mhz.ts that contains 30 seconds of full multiplex data. You can then upload it here on the file upload option when replying.

Thanks!
