Sony, Sharp, Hitachi, Samsung, Motorola and Amimon Create Wireless HD Standard

By Dennis P. Barker
Several major manufacturers are backing a new initiative to promote and develop WHDI.

Amimon, Hitachi, Motorola, Samsung, Sharp and Sony are announcing the formation of a special interest group to promote and develop the WHDI (Wireless High Definition Interface) Protocol as a comprehensive new industry standard for multi-room audio, video and control connectivity that allows the streaming of secure, encrypted HD video. Other smaller companies like Belkin may join later. The group's objective is to enhance the current WHDI technology. The consortium's primary focus right now is to complete the new worldwide standard this year, and launch WHDI-enabled products in 2009 that will offer secure wireless streaming of uncompressed HD video and audio.

Developed by Amimon, WHDI is capable of sending uncompressed HD signals with a maximum resolution of 1080p/24 frame rate @ 120Hz refresh at a frequency range of 5.1 - 5.8GHz. This technology reportedly offers a range of up to 100-feet, and is capable of passing through walls. Reportedly, the WHDI Protocol maintains superb image quality and robustness of sights and sounds with less than 1 millisecond latency. Pre-standard products have been announced by Belkin in their new FlyWire products as well as Sony with their BRAVIA Wireless HD Link. A key ingredient of WHDI technology is a seemingly revolutionary video-modem that operates in the 5GHz unlicensed band that helps to enable wireless delivery of uncompressed HD video (including signals up to1080p).
