Live Intel WiDi Demonstration At CES 2010

MojoKid writes "As we saw earlier this week, Intel's new WiDi (Wireless Display Interface) technology will start to be bundled with various Core i5 and Core i3 notebooks later this month, promising to address the Home Theater and Multimedia PC markets with a solution that enables wireless connectivity of your notebook over HDMI to an HDTV using standard 802.11n wireless technologies for transmission of the data. Intel was also demonstrating this technology live at CES 2010 and HotHardware captured video of the technology in action, with Intel Product Manager Joshua Newman. This new technology is obviously fairly mature at this point with retail products waiting in the wings, just a few weeks away."

Not good enough

This solution is simple transcoding, using a lot of CPU. They are probably picking the framebuffer from the display driver, providing it to a userland application that does the encoding and sending.

I expected a true lossless wifi link to the DVI/HDMI connector, this is a vendor-specific dirty hack.

802.11n doesn't have the bandwidth for lossless video of a decent resolution. Uncompressed 1080p is something like 3Gbps, right?

Don't get me wrong, I'd love to have wireless connections pushing 3Gbps. We just aren't there yet. You can get decent video quality at 802.11n rates, though. More than anything, I'm just a little surprised by the idea that they're able to do real-time high quality transcoding.

cool, but what about sound

[dan_in_dublin]

it's cool that I no longer need to drag cables across a room just to use a projector, but it would be even nicer if i could play back any media on my pc and have the images and sound on my tv.. does anyone know if this includes the sound? i owuld expect not as I dont see how it could capture and correclty sync the sound without being part of media framework and that would necessitate a particular playback applicatio. it seems from the article this is application independent. shame as that youtube video and sound redirected from pc to tv would have been cool

Or a 99 cent hdmi cable and a netbook.
