First, keep in mind very few local channels are putting up their signal via satellite. The issue isn't the technology, it's the contracts the local channels have with the program providers (whether network, syndicators, or even advertisers). Those contracts could (and in some cases do) prevent locals from streaming to out of market locations.
Think you misunderstood my point.What I mean is,that several local channels that are available via sat can be watched outside of their dma,by (moving).As you said (I would still make the argument that only people in the DMA can get the signal).I'm sure that same argument is used currently for satellite.
