Multiple tuners?

Added by David Brown over 10 years ago

Just thinking. My setup is basic - one tuner. I was wondering how many tuners it might be possible to add? I assume you could feasibly put a workable number of 3 or 4 on it?

How would this work if they were all the same make and model of USB tuner - would TVheadend see them all? Also, if you program with the EPG does TVheadend just pick one of the tuners not in use if recordings clash?

I am interested as I'm thinking of getting one or more tuners to add to the system.

Thanks :)

As far as I know, the linux kernel supports up to 8 tuners. This can be extended if you recompile it.

I'm using 7 tuners in my setup, with multiple tuners of the same brand. TVheadend automatically picks a free tuner for recordings.

^^ wot he said.

I've got four tuners on my system - two the same, then one each of two other brands. The channels can be merged so I can pick whichever tuner is free, even across DVB-T(2) and DVB-S2. You need to think about how tvheadend works - networks, muxes, services, channels and tuners - they're not 1:1 mapped.

USB tuners can be a challenge because of the way in which Linux assigns numbers on boot - simply, it means they can move around. Using the same tuner type actually works in your favour here, as it doesn't matter whether identical tuners are ABC, ACB, BAC, BCA, CAB or CBA. There are ways and means to hold the buggers in one place otherwise, though.
