Pixel/Blocks with some SD Channels

Added by David Simon about 7 years ago

Hi@all,
I´m running TVHeadend 4.1-2332~g38c9e89 on a Raspberry Pi as Server and two Libreelec Raspberries as TV Clients.
Everything works fine for about 6 Months now but one thing I couldnt figure out: Only two SD-Channels (German RTL and SAT.1) are unwatchable. It shows blocks/pixels always buffering and so on.
I´m using Cable-TV as Source and my Provider is Telecolumbus. As TV-Input I use two TV-Sticks on an Amplifier.

Does anybody have a hint/idea for me what I could try to do or where I can tune the particular channels?

I appreciate any kind of help.

Cheers, David

What are the frequencies?

Hi Thomas,
is 121/122Mhz I guess.

What range is the amplifier?
It could be that those frequencies are at the bottom end and not getting boosted as much.

Hm could be but I think there are also other channels on the same frequency as those two but I will definitely look it up when I'm home. Thanks for the hint

Or they are over-boosted

Sorry for the late response. I digged a bit deeper and I can say is not the amplifier. I bypassed the amplifier and checked the signal directly with one receiver and I have the same problems.

I tried to put the receiver also on my windows pc to check if it is a TVHeadend realted problem or just crappy signal but unfortunately my stick doesn't work on Windows 10 anymore.

If it matters the Amp works between 48 and 800 Mhz
