    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".
