At the recent infoComm EXPO, Sanyo demonstrated wireless transmission of high definition video between an HD DVD player and projector, using WHDI (Wireless High-Definition Interface) technology developed by Amimon.
The technology enables wireless transmission in the 5GHz band. Theoretically, uncompressed high-definition 1080p video can be streamed with the equivalent video data rate of 3Gbps using 40 MHz of bandwidth. Data rates up to 1.5Gbps (enough for 1080i and 720p, says Amimon) can be delivered using a more economic 20MHz of bandwidth.
Amimon claims the technology is robust enough to transmit HD over a 100ft, through walls. Semiconductor chips based on WHDI are expected to be available to consumer electronics manufacturers in 2007.
InfoComm, the AV communications and technology EXPO, which ran in Orlando, Florida, June 3-9, claimed brisk business on its opening day, with over 25,000 attendees. A record 770 exhibitors participated at the event, representing an increase over the previous record of 725 in 2005
