Get ready to ditch multiple cable boxes. Maybe
Several industry giants, including Sony and Samsung have tentatively embraced WHDI. What's this WHDI of which we speak? In short, it's a wireless protocol intended to move HD video from TV to TV wirelessly around the house. Yes friend, imagine one cable box to get your HD channels anywhere in the house. At least that's the theory. Unanswered questions include how many different channels can be watched at once, and what happens when more house have these systems: What about interference? Apple is not part of the consortium, which isn't huge surprise since it's focused on TV manufacturers, and as of today, there's no "TV" in the AppleTV.
But for those in the Apple world, the question becomes will Apple products play nice? Will you be able to have an AppleTV in one room, and watch the content in other rooms without additional Apple TVs/Airport base stations/MAcs/etc.? This might just mean an extra box after all.
