Electronista: The WHDI wireless HD video standard that uses 5GHz, Wi-Fi-based technology has been finalized recently.

The technology was found by chip designer Amimon and is one of at least four technologies aimed to bring wireless HD video distribution in the home. The technology will allow sending 1080p HD video at 60Hz refresh rates and 12-bit color depth up to 100 feet away and through multiple walls.

Maximum data rates are said to be fixed at 3Gbps using a 40MHz channel. Initially, Amimon promised only support for 720p video, but the technology has evolved and it now also supports the full High-Bandwidth Digital Content Protection (HDCP) version 2.0.

There is also a version of the Consumer Electronics Control protocol from HDMI included, which would allow users to send video to multiple rooms. The Amimon chips comprise of individual two-chip receivers and transmitters that use a 90nm CMOS baseband and a silicon germanium radio, while consuming up to 3W of power.

Members of the consortium can have access to the technology for a fee of $2,000 per year if they sign up in 2009. The WHDI Consortium hopes to create an interoperability test suite and certification lab in the autumn of 2010, with the first products using the standard available at around the same time. Competitors include the WirelessHD standard and the Wireless Gigabit Alliance, though the former doesn’t have HDCP 2.0 support.

Several TV makers have already committed to the WHDI standard, including Sharp and Sony, but LG, Hitachi, Motorola and Samsung are also part of the consortium.

Cdfreaks.com: During the Consumer Electronics Show (CES) next month, several companies will discuss at least four different wireless high-definition TV standards.

A panel discussion between vendors and representatives of the following formats will take place:  AMIMON, a WHDI supporter; Pulse-LINK, HDMI supporters; SiBEAM, wireless HD supporters; and ProVision, the 802.11n backer.

Out of the four standards, only 802.11n “is the only standard capable of cost-effectively transmitting interactive wireless HD video across all rooms within a home,” said Professor Andrew Nix.

Broadcom, Hitachi, Motorola, Samsung, Sharp, and Sony joined the WHDI Special Interest Group (SIG), in the hope of creating and promoting a new 5 GHz platform. Intel, Panasonic, LG Electronics, NEC, Toshiba, Samsung and Sony also are supporting a 60Hz technology used by Wireless HD.

“SiBEAM has recently completed a new round of fundraising, successfully securing the participation of two major backers, Panasonic and Samsung,” ABI Research analyst Steve Wilson said in a statement.  “Broadcom has also joined the consortium.  Meanwhile Mitsubishi has announced its choice of the Amimon chipset.”

SlashGear: We’re finding out more details about the Sony DMX-WL1t, the companies first WHDI device to transmit video wirelessly in your home.

The device first showed up in January at CES, and is making another appearance now, but now with more details.

The DMX-WL1T will have four HDMI inputs, a stereo analog input, a digital audio input, and a component input.

The system will have the ability to transmit uncompressed 1080i video and audio to any BRAVIA HDTV with Sony DMex compatibility.

The device reportedly has a transmission range over 100 feet, so you could hook everything up in one room, and then play it onto a television in another.

DVICE: Imagine watching any HD video wirelessly from any Blu-ray player, PC, TiVo, set-top box, video camera, Xbox — any video source, anywhere in your house, up to 100 feet away.

Now add the ability to instantly control that video from wherever you’re watching it. That’s what WHDI (wireless high definition interface) can do.

This week a group of the largest consumer electronics companies in the world were agreeing to standardize this new way of moving wireless high-resolution uncompressed video, so that all their products with the WHDI logo will be interoperable. They say we’ll start seeing a variety of products with WHDI technology by 2009.

The revolution has already started. The idea is the brainchild of Amimon, an Israeli company that’s figured out how to move the highest-resolution video around with no added noise, no annoying waiting after you push the Play button, and, eventually, low cost. We’ve already seen products demonstrated using WHDI, including a TV from Sharp now shipping in Japan, a set-top pair from Belkin set for late 2008 release, and a wireless HDTV demo from Sony at CES 2008 in January.
