Tvheadend

Hello ppl,

i would like if someone could help me with some inputs what i need to achieve this goal.

We have local operator which give us TV over coax.
Is it possible to use one receiver and record multiple channels at same time.
What hardware - setup we need?

I am Linux familiar, Tvheadend is fired up, tested with some IPTV streams, works fine, but I am total newbie regarding question mentioned.

If someone is interested in paid job? please let me know.
