Intel Wireless Display - transfer images wirelessly today
We started talking about wireless video transmission for quite some time. In 2006, the Wireless HD Consortium was created, which currently includes Broadcom, Intel, LG Electronics, NEC, Panasonic, Philips, SAMSUNG, SiBEAM, Sony and Toshiba. In 2008, the first specification of the Wireless HD 1.0 standard was approved, which implies the use of a 4Gb / s wireless channel at 60 GHz. The second version of the specification - Wireless HD Next Gen, adopted literally the other day, suggests the use of a 10 Gbit / s channel. All this naturally implies the development of fundamentally new, expensive equipment, which delays the mass distribution of this technology.
Intel, apparently, decided at this stage to go its own way, and together with Netgear at CES 2010 demonstrated in action the technology that allows you to transfer an image of 720p using all the usual Wi-Fi.
Meet: Intel Wireless Display.
The connection uses an 802.11n wireless connection and from the special equipment requires only a small device that connects directly to the screen.
The forces of the central processor compress the image, after which it is transmitted to the receiver, which decodes it and outputs it via the HDMI interface.
The processor load on the test bench (Sony laptop with an Intel Core i5 540M processor) was 15–20%. When broadcasting videos from the YouTube HD service, the use of the channel was within 5 Mbps.
Currently, the technology is limited to 720p resolution, HDCP support is also not, but Intel promises to present all this in the next version.
A special receiver so far offers only Netgear, it will be supplied with some notebooks, or separately, and at a very affordable price - $ 99.
The start of sales is scheduled for January 17th.

UPD: judging by the comments, not everyone understood the essence of technology. This is not streaming video over the network. This is a “wireless monitor”, to which you can display anything, respectively.
The title is also slightly corrected.
