Create the same one mix channel... but have it mirrored on several channels, and then only authorize people to see the game mix channel that wont break the blackout rules... Not sure if they can do that with mirrored channels or not, but its the only thing I can think of that might work. If there is four games though, that would mean they may need up to four mirrors for the afternoon games, and six mirrors for the morning games, I believe.
I can't quite tell whether you're advocating for...
1. "The same one mix channel" containing every game, blacked out in areas where a game may be blacked out.
2. Separate mix channels for areas where there's a blackout, i.e., if a Buccaneers home game is blacked out, then most of the country gets a mix channel containing every game, and Central Florida gets a mix channel that contains all games except the Bucs game.
Neither scenario would involve "mirrors," a term which implies that the content is the same on all channels. #1 only requires one channel; #2 would require DirecTV to produce and distribute two completely separate mix channels.
