No free adapter, need some info please
Added by Hyperion Moderkart over 7 years ago
Hello,
I've succesfully installed TVHeadend and everything is working including EPG. I wonder about something though. If I start watching a channel from one device, I can't watch another channel from another device since I'm getting the No free adapter error. Can someone explain why is this happening and how to solve it? Sorry I'm totally new to this.
Thanks in advace

A tuner can only tune to one frequency at a time, you need additional tuners to watch more than one. A single frequency can carry a number of services multiplexed together in a transport stream container, hence mux/multiplex.
See http://docs.tvheadend.org/before_you_begin/ for a much better explanation.

Thanks for your answer and expanation. Just to check if I get it right... lets say that I have 40 channels that belong to 10 different muxes and I have 10 users. And mets say that each of this user watches 1 channel that belongs to a different mux. Do I need 1 tuner for each mux in use? So do I really need 10 tuners?
Thanks again

Correct. Each mux tuned needs a free tuner. If your tuner is already tuned to a mux and a second channel is requested on a different mux, you need another tuner to open that second mux.

I have found the following article - How to stream multiple TV channels with a single DVB-T tuner using VLC: https://evilshit.wordpress.com/2013/08/10/how-to-stream-multiple-tv-channels-with-a-single-dvb-t-tuner-using-vlc/. So, maybe it is possible. I haven't checked yet.

Well, it's possible, but only for a specific situation. This is only the case if both channels/programs that you wish to watch/tune are on the same mux. If they're on the same mux, Tvheadend will change the PID filter to allow both programs to stream.
If the different channels that you wish to watch are not on the same mux, then you cannot stream both channels.
