What's so great about WHDI? You'll be able to connect a TV wirelessly to a home theater receiver, TV can be extra-slim TV because they don't need all of those internal electronics. Or, think of being able to watch and control a Blu-ray disk wirelessly from your home theater on any TV in the house, even 100 feet away. Imagine being able to play and control your Xbox 360 located in the bedroom, wirelessly while you sit in your home theater. That's what's coming with WHDI 2.0.
Now what would be nifty, is if you can decide what channel should be sent to which source. So as mentioned in the earlier article, the race is on between USB 3.0 and WHDI.
