They can share spot beams for different channels? I assumed it was a certain spot beam for a certain channel per market? Maybe I don't understand the tech at all.
I'll just give an abstract example. Let's say a spot beam can carry 8 unique channels (again, I don't know what the exact number is). It can be different sizes and say it's big enough it covers 2 markets that are next to each other, one big, one small.
So the big market has 4 stations. Say the small market only has 2. Then can then put those 2 up on the that spot as well and leave room for the local RSN in HD.
I'll take my neck of the wood as a great example, Michigan.
A good bit of the east side of the state is the Detroit market.
Most of the west half is my market, Grand Rapids/Kalamazoo. In between are 2 quite small markets for Flint/Bay City/Saginaw and Lansing. They certainly won't waste a whole spot beam just for those 2 smaller markets if they can help it. Most likely they have 2 large spots covering both Grand Rapids and Detroit and both cross over to cover the 2 smaller ones. Betwen the space left on those two spots they can toss in the stations of the smaller markets. Thus a small market like Flint is scheduled to go up before many larger markets because a spot beam from a near by large market has space left on it.
They did and do this alot with the SD local spotbeam, I see no reason why they wouldn't with the HD ones.
Green Bay is probably going to have it's own spotbeam to be able cover most of the UP of Michigan, some of the western part of which is part of the Green Bay DMA. They could also make a pretty large one to cover both Green Bay and Duluth, MN. Lots of options.
