You know... if you have access to, and licensing for, equipment that will send video that far,
you should know the answers to your questions better than the rest of us
Not trying to be sarcastic... just stating facts here.
If you don't have the license already, I doubt you'll find anyone, with enough knowledge
to help you, who will actually spend the time to help you... until you acquire it.
I see that you're not here in the states, so the above may or may not apply to you.
