WirelessHD 1.1 Specification Supports 4K Resolutions

Back at this year's International Consumer Electronics Show, the Wireless HD consortium revealed that it had just about finished defining the Wireless HD 1.1 specifications, meant to enable very high-quality videos to be transmitted without cables. Now, the consortium seems to have finally finished its work, having issued a press release detailing how Blu-ray players, HDTCs, PCs and portable devices may transmit, share and display content and instantaneously transfer large, multi-gigabyte media files.

The 1.1 specification has the highest wireless bandwidth ever achieved, namely of 10-28 Gbps. This will make sure that displays with higher resolutions, deep color and high frame rates are supported. The specification also has an optimized architecture, which handles multi-gigabit data rates for A/V streaming and media files at the lowest power. Also, connected devices that support WPAN Data will be able to carry out sync'n'go file transfers for portable and fixed electronics.

One of the most important features made possible by this newest specification is the support for 4K resolutions. Basically, the maximum HD resolution that can be transmitted over wireless is four times beyond 1080p. The other important element is support for 3D formats. Other benefits include scalability, which lets even portable devices take advantage of the new standard, and HDCP 2.0 content protection.

“We’re pleased to bring an outstanding second generation specification to market with significant feature enhancements and power efficiencies,” John Marshall, chairman of the WirelessHD Consortium, said. “Enhanced video support and added data support makes WirelessHD technology the best option for wireless video area networking (WVAN) and wireless personal area networking (WPAN) applications.”

WirelessHD 1.1 is the only standard that supports both streaming and copying of multimedia content. The technology also lets compatible devices connect to the network and the Internet, via WPAN. More information, of course, can be found on the official website.
