Tvheadend

Hi everyone,

I plan to build a TV headend Docker on Unraid. 9 users should be able to stream from it at the same time.
Do I need 9 tuners here or is it sufficient to operate 4 tuners each with one level (HH, HL, VH, VL)?

I am currently using TV-Headend privately. Here I use a satellite IP receiver. Would this also be a recommendable variant for the project described above?

Greetings and stay healthy
