The WHDI chipset supports most video resolutions, at up to 720p and 1080i (including XGA), with no line of sight required between the transmitter and receiver and with latency of less than 1 millisecond. This means the video can be streamed over a standard wireless LAN 20 MHz connection, reaching a speed of 1.5 Gbps. The chip also enables the delivery of uncompressed 1080p HD content transmission at a 3Gbps rate through a 40MHz channel. Amimon is focusing on information coding and their strong, 256-bit AES encryption system significantly reduces the relatively high bit error rate present in other wireless links.
Unlike a wireless data modem, where all data bits are treated equally, WHDI takes the uncompressed HD video stream and breaks it into elements of importance. These are later mapped onto the wireless channel and elements with more visual importance get a greater share of the channel resources and are transmitted in a more robust manner. The result of this approach is that errors in the wireless channel are unnoticed as they only affect less important bits. In this way, very high rates of video information can be transmitted without any visible defects.
The company’s products were recently presented at the 2007 Consumer Electronics Show (CES) in Las Vegas, Nevada. The differences in quality between a wired screen and a WHDI system were unspotted at the CES demonstration. “Wireless video has been talked about for many years, but it never became a reality. It hasn’t been practical to deliver it without compression, until now” – said Amimon’s Vice President of Marketing, Noam Geri.
The company is looking forward to start integrating its technology into consumer electronics products by the end of this year. DVD’s, gaming consoles, projectors, LCD’s and plasmas – all these are devices that can be paired with Amimon’s technology to create an all-wireless home and office environment. Geri says that consumers will see a variety of WHDI-based consumer electronic products in 2008.
