NVIDIA says they will be embracing the upcoming Miracast Wireless Display standard with their mobile Tegra 3 chipset, and are actively working with other vendors and OEMs to bring this technology to market once the Wifi alliance gets all the details worked out. What we're talking about here is an open standard and method of sharing what you see on your screen, with any other screen that supports the new technology. Things like televisions, computer monitors, tablets, and even smartphones should be able to instantly, and wirelessly, share screen output. Playing Shadowgun THD is fun, but playing it on your 42-inch TV is even more fun, and of course full-length HD movies just scream for thi type of tech.

NVIDIA will be optimizing the experience by using the existing Tegra 3 architecture and new industry standard Miracast stack to process and accelerate content, then transmit it via a device's Wifi chipset as an H.264 bitstream. In practice, it should work much like current offerings from Intel or HTC's Media Link dongle package, but using an open standard. Open is good, as it allows other vendors to use and enhance things as well. More bright minds at work means more and better features and scalability.

NVIDIA expects the standard to be ratified by the Wifi alliance within the next few months, and will release more information once that happens. There will be new hardware involved, but it's possible that using docks and dongles your existing devices and displays could take advantage.

NVIDIA announces plans to support Miracast Wireless Display standard

I've been waiting for this kind of technology. AirPlay looks cool, but I'd love to have this technology without requiring an Apple TV and iOS device.

I can't believe lag is low enough to play games on it.

The HTC/Intel WiDi ones are too laggy (1-2sec lag)...this looks like it has almost 1/2sec lag too...

As long as this becomes THE standard rather than A standard for wireless android, I'm happy.

The real question is whether or not existing Tegra 3 devices would be able to take advantage of this. Would cover up one of the only flaws in the Nexus 7.

Most of the hardware in today's SOCs (Qualcomm Snapdragon, TI OMAP4, NVIDIA Tegra) already have built in H.264 and audio encoding (they use it for the camera already) to make conforming to Miracast a reality. As some of the other commenters pointed out, the real question is whether or not they can do it with acceptable latency for gaming. It's very likely that older and current generation TVs would need a dongle if they don't support Wi-Fi Direct or have playback support for the bitstream format. I would therefore think that Nexus 7 and today's latest and greatest smartphones should be able to support Miracast to some degree.

Can you not do this by WiFi, now? All I know is having a hdmi cable hook up is a pain, you got a mini hdmi to deal with, and you need at least a 6 m cord to run to th tv if you want to actually use your tablet...
