Intel presents Wi-Di technology for wireles video transfers

Televisions will require a special adapter made by companies such as Netgear - which will cost around $100 - to receive the wireless video signals.

It means users can download or stream HD content on their laptop, and watch the footage on a large HD screen at the press of a button.

Wi-Di was part of a keynote speech that was dominated by video, and especially 3D. Each of the thousands of attendees were given 3D glasses and were treated to big-screen footage of forthcoming 3D movies, as well as an Intel demonstration of on-the-fly 3D video editing using Core i7 processors.
