The Intel Wireless Display technology (WiDi) was first introduced at Consumer Electronics Show 2010 in January.
WiDi implies transmitting compressed graphical content over Wi-Fi.
At IDF 2010 the technology was showcased in action on the example of a regular ASUS notebooks with 802.11n support. The notebook used a standard Wi-Fi connection to send content to a device created by Netgear.
Except for a Wi-Fi receiver, the device featured a decoder and could output content to HDMI as well as composite and component interfaces.
In general this all means that you can launch a movie player on a computer and watch the movie on a large-screen TV. HDCP isn't supported yet, but the company promises it will be added. When that happens, you'll also be able to watch licensed content, e.g. Blu-ray movies.
It's interesting that, while playing a movie, the notebook display can be used for other tasks.
Of course, you can output your desktop onto the TV as well.
Note that WiDi is aimed at regular Wi-Fi connections used by PCs and notebooks. You won't be able to connect a PS3 to a TV set this way. But that has never been the goal anyway.
