Intel WiDi is a solution that enables a user to wirelessly project his or her
PC display to a TV across the living room or a projector conference room. The
experience is similar to a consumer connecting his or her Notebook PC to a TV
via an HDMI cable. Full desktop (including text, presentations, pictures, web
content, commercial video discs such as DVD and Blu-ray, and online premium
content services like Intel® Insider video) are sent to the TV and audio, up to
6-channel 16-bit/48 kHz LPCM multi-channel audio is rendered in-sync with up to
1080p HD video. This is made possible through a TV adapter that is connected to
the TV via a standard HDMI connection or integrated into the HDTV. The TV
adapter or integrated receivers wirelessly communicates over 802.11g/n with the
WiDi enabled PC and receives its display information in a standard video format.
The usage model is simple: a user with an Intel WiDi Technology-enabled
laptop is in the same room as a TV (e.g., living room) with a TV adapter
attached or integrated in to the TV. The user selects the adapter/receiver as
the source in the TV input selection, and initiates wireless connection from PC.
The PC display and audio, if present, will be sent over the wireless connection.
Though it is generally useful for desktop remoting, applications requiring very
low latency interactions may not be usable.
The adapter setup (first time use) is secure & simple. At the first power on
and connection attempt, the adapter displays a security code on the TV screen.
The user enters this security code during the initial launch of the WiDi host
software, thereby pairing the adapter and host.
