The trouble of repacking the TV band is: It won't work! A 6 mHz HDTV channel has 19.3 mbps of bandwidth available SD (480p) requires 3+ mbps bandwidth 720p HDTV requires 12+ mbps bandwidth 1080i HDTV requires 15+ mbps bandwidth Do the math: there simply isn't enough bandwidth in one HDTV channel for even 2 720P pictures. -D
