The original NVIDIA SHIELD (before the Tablet or the set-top box, so just called "SHIELD" at the time) was a surprise revelation at CES 2013. This high-powered Android device with an Xbox-style controller and a flip-up screen was unlike anything we had seen before, and though it never became a runaway hit, many (including yours truly) have been hoping that NVIDIA would update the design in addition to its more conventional SHIELD entries.
NVIDIA has just announced that the Tegra 3 chip will support the Wi-Fi Alliance's upcoming wireless display technology, called Miracast. Miracast uses Wi-Fi Direct to wirelessly deliver HD content - including movies, images, and games -from mobile devices directly to supported devices, like HDTVs and set-top boxes.
For an example of what will be possible with Miracast, have a look at this:
The Miracast wireless display certification program should launch within the coming months, enabling display manufactures and other vendors to start incorporating the standard into future devices.
