Suddenly very slow Channel-Switching

Added by hen fri over 5 years ago

Hello,

I first noticed it after a reboot, but I am not sure that this caused it:
since a short while switching channels is very slow (7 seconds).
This is both from Kodi, but also from TVHClient (android)
In the log I see:

In the web-interface, I see this status (I have triggered some recordings in order to ensure all adapters to be used):

Can you hint me, at a possible reason for this? I am not aware of changes in the configuration I made recently.
I am happy to provide additional information if needed.

Regards,
Hendrik

Hello,

I have the impression, that tuning to the channel takes that long. If I select a channel that is currently being recorded, switching is fast...

With so bad signal, it is miracle that you watch anything.

RE: Suddenly very slow Channel-Switching - Added by hen fri over 5 years ago

Hello,

how/where do you see, that the signal is weak?
The SNR/STR are not comparable between devices, that's why I ask.
I have another Receiver on the same Dish and it works flawlessly.

Greetings,
Hendrik

RE: Suddenly very slow Channel-Switching - Added by saen acro over 5 years ago

SNR /Signal to Noise/ ratio is less then minimal that's why is in red.
Do you use transcoding this also can reduce switching speed.
also how is wired your tuners there is high and low band on image

Ku-Band: low band from 10.7GHz to 11.7GHz and a high band from 11.7GHz to 12.75GHz.

RE: Suddenly very slow Channel-Switching - Added by hen fri over 5 years ago

Hello,

thanks for your help. I appreciate it.

I will check with the other receiver tomorrow. I do not know what the SNR was in the past. We had some windy days recently. Maybe the dish is out of direction.
I am not aware of using transcoding, but I will also check that.

Regarding "also how is wired your tuners there is high and low band on image"
Do you mean the Tuner #0 which is at 11493.75*H*? I think the H is the polarization. So I do not see where you see high/low band on that image.

Hendrik

RE: Suddenly very slow Channel-Switching - Added by saen acro over 5 years ago

Tuner #0 frequency is in low band other #2 and #3 are in high band
to work this scenario you need quad lnb or quattro lnb + multiswitch

RE: Suddenly very slow Channel-Switching - Added by hen fri over 5 years ago

Hello,

yes, I have a quattro lnb and a multiswitch.

Greetings,
Hendrik

RE: Suddenly very slow Channel-Switching - Added by hen fri over 5 years ago

Hello,

I understand now.
First, I checked the orientation of my dish --> no improvement possible
Then, I found that TVH always first tries to use tuner #3 and then uses another tuner.
I then deactivated #3. This fixed the problem.
Some hours later I found that one of the Cables was loose.

Thanks again fo the help!

Hendrik
