Nvidia Supporting Miracast Standard with Tegra 3

From Tom's Hardware: Nvidia, a member of the Wi-Fi Alliance, announced that it's supporting the new Miracast WiFi-Direct based protocol which is expected to launch by the Wi-Fi Alliance within the next few months.

For the uninitiated, Miracast will be an open standard, so any mobile device or display manufacturer will be able to implement the technology. It will also be a direct competitor to closed eco-systems like Intel's WiDi and Apple's AirPlay which enable users to wirelessly stream videos and games to external displays.

There are also other open standards for streaming media such as DLNA, but these are plagued with interoperability issues that have limited their traction in the market place. To address the limitations of these solutions, the Wi-Fi Alliance created its upcoming open wireless display standard called Miracast.

"Underpinning the Miracast specification is Wi-Fi Direct – a specification defined for peer-to-peer, direct wireless connectivity between devices," Nvidia said on Thursday in its whitepaper. "Miracast Certified devices will be able to connect with each other directly, without the mediation of a wireless access point, by leveraging the functionality introduced by Wi-Fi Direct. When two devices connect with each other directly, one assumes the role of the source (transmitting device) and the other becomes a sink (the devices receiving and rendering the content to the user)."
