Alot of people haven't heard of WHDI which is basically wifi for HD video.
Currently the technology is in its infancy with initial implementations being usb dongles that allow you to stream video from your phone or tablet to your tv like this product:
This technology will become the standard for wireless video technology because it uses HDCP to make the people in hollywood happy. Next generation tablets, laptops and phones will all support this technology and it will be standard in new televisions as early as this Christmas Season.
This product will be a massive success in that it solves the problem of the set top box or home theatre pc for retail consumers and will also simplify setup for anyone with alot of tvs.
Watch WHDI over the coming months and see what happens. I'm expecting all devices to support this at the next CES.
