Tuner management

Added by Michael Weser about 3 years ago

Hi!

I'm using TVheadend 4.3-1980~g1ee9c5b9c on Debian bullseye with a TBS 6504 quad tuner card. The inputs are assigned as follows:
1. Astra 19E/Astra 28E/Hotbird 13E/Astra 4,8E
2. Astra 19E/Astra 28E/Hotbird 13E/Intelsat 1W
3. Astra 19E/Astra 28E/Hotbird 13E/Eutelsat 9E
4. Astra 23,5E

All of these satellites are assigned via their corresponding network. Input 1-3 are hooked up to a DiSEq switch and as far as I can tell, all of these work.

The problem:
Currently there is a recording on Astra 19E, which happens to use Input #3. Now I would like to watch a channel from Eutelsat 9E, which is only available at Input #3. This request got rejected, as there was "no input source available". Somehow I would have expected that the recording would move to Input #1 or #2, as they were free at the time and carry the same satellite feed (Astra 19E) as input #3.
Did I expect too much and such a feature is not implemented or might there be an error in my setup?

Cheers!
Michael

TVH doesn't have any kind of 'strategy' capability. When a new subscription is requested (for recording or to watch live TV) TVH finds which service / tuner combinations are available at that time and selects the one with the highest priority; if several have the same priority it seems to choose the first one it finds. AFAIK TVH only switches to an alternative source if its first choice supplies no data from the time it was selected.

Unfortunately in your case there is no way of changing priorities which will remove the possibility of a clash. However if, for example, you seldom use 4.8E you could increase the priority of tuner 1 so that recordings from 19E 28E and 13E default to using it, leaving the others free.

Thanks for clearing that up for me. I guess I make due with prioritizing inputs, at least for now. If this bugs me long enough I might give it a try and see, if I could implement that feature.
