LG Signs On WHDI Bandwagon LG, 14 Other Tech Companies Adapt WHDI Wireless Video Standard
space. We've seen Intel's WiDi (wireless display) technology, as well as
WirelessHD, but now AMIMON's new standard, dubbed WHDI (Wireless Home
Digital Interface), is gaining traction, as LG signed on to adapt the
standard at CES last month.
On the technical side, there isn't anything about WHDI that makes it
stand out form its competitors. It transmits on a 40 MHz channel in the
5 GHz radio band, wirelessly connecting your video devices and HDTVs.
The spec claims it's capable of 3Gbit/s and transmitting uncompressed
1080p video. Of course, that's in the United States, where the 5 GHz
band is unrestricted. Internationally, WHDI devices will transfer video
a bit slower at 1.5Gbit/s. AMIMON, the developers of the WHDI tech,
claim it has a range of 100 feet (30 meters) and the latency on WHDI is
less than 1 millisecond.
The new standard was only finalized in December of last year, and held
its big coming out party at CES 2010, where several big companies agreed
to adapt the technology, including LG, who vowed to deliver several HDTV
sets that carried the technology. Sharp will also delivery TVs that use
the technology. Other big names, including Sony, Hitachi and Samsung,
have signed on to adapt the technology, but haven't promised any
products carrying the tech yet.
No word what this means for Broadcom's WirelessHD standard, which Sony,
LG, Samsung and others had previously signed on to adapt. WirelessHD
operated in 60GHz band and offered theoretical transfer speeds of
25Gbit/s (famously, they said that their transfer speeds could be faster
than wired HDMI one day).
Despite all the excitement over WHDI, no word on when we can expect AV
gear and HDTVs carrying the technology to start appearing in stores.
