Hi,

I do have 3 Panasonic's AX,CX,DX Series, minisatip is working here.
Check the divers for bugs in regards to mess up UDP packets, this was happen to me some time ago with a Intel eth.
Check with "nstat | grep -i udp" for dops, errors eth.
What need to be considered is tuning the network stack on the Server where minisatip runs and checking the network devices for duplex mismatches or if there are AVM Fritzboxes in the path (then disable "green mode" on the ports).

Code: Select all

net.core.wmem_max=20491520
net.core.rmem_max=20491520
#net.ipv4.tcp_rmem= 10240 87380 125829120
#net.ipv4.tcp_wmem= 10240 87380 125829120
net.ipv4.tcp_mem = 65536 131072 262144
net.ipv4.udp_mem = 65536 131072 262144
Wireless and Powerline should also avoided.

If artifacts showing up try adding "-H5:50" to the minisatip cmdline an check again, it helps here for my Pana AX and a small delay behind a MOCA bridge.
If there CI modules in the TV then try without, or if the CI module is a Diablo CAM increase the delay option in the config menu of the cam.

the only real issue I see atm is "Panasonic no signal after manual scan" https://github.com/catalinii/minisatip/issues/502

with this patch it works better for me but it's probably not the right way to solve it, so use it at your own risk.

there are some other issues but they are not specific to Panasonic TV's.

Hi,
I continue the test. While the signal was not lost once. But since this problem was not constantly manifested, I was in no hurry to answer. But I think that there is a positive result. Thanks again for the quick response and real help.
