Good day! I am very confused with Single Frequency Networks and
Multiple Frequency Networks when used in digital TV broadcasting.

I grasp the concept of MFN architecture okay. I can see that different
TV stations will require a different transmitter at a different
frequency when transmitting the same program in order to increase
coverage.

With this, I can safely assume that a TV station using a SFN setup
will still require multiple transmitters for the same program, but
this time only use one frequency.

But I do not have the answer to whether multiple TV stations with
different programs is possible in 1 SFN setup. I keep reading about an
SFN architecture being spectrum efficient. What exactly does this
mean? Is this indicating that different TV stations can transmit their
programs just using 1 SFN setup?

Include physical distance in the SFN concept. Also called "area of
coverage".
