CES2006: Amimon Offers Wireless Transmission of Uncompressed HD
Amimon will demonstrate its new WHDI (wireless high definition interface) semiconductor technology at CES this week, using what it calls a "wireless video-aware modem chip" to transmit HD streams that will be provided through uncompressed HD video interfaces such as DVI, HDMI and component video.

Amimon said the new technology will permit HD flat-panels and multimedia projectors to interface to all HD video sources via wireless links. In a statement, the firm said initial rollout of retail product is set for the second half of 2006. The company also said it recently completed two weeks of demos for manufacturing execs in Japan and South Korea.

Several technologies are under development to deliver compressed HD video, including Ultra Wideband (UWB) and IEEE 802.11n, although compressed video streams such as MPEG are typically not provided at the outputs of most consumer video devices such as DVD players, STBs and gaming consoles. Adding re-compression hardware to UWB or 802.11x solutions increases costs and inevitably degrades the quality of HD video, Amimon said.

The company says its patented WHDI eliminates the need for additional compress/decompress components. It says latency response is equivalent to wired HD, at less than one millisecond. The technology enables wireless delivery of original HD video with video data rates of up to 1.5 GB, according to Amimon, and operates in the 5 GHz unlicensed band.

The Best Deconstruction of a 4K Shoot You'll Ever Read
With higher resolutions and larger HD screens, wide shots using very wide lenses can be a problem because they allow viewers to see that infinity doesn’t quite resolve into perfect sharpness.
