Wireless Home Digital Interface (WHDI) is a consumer electronic standard for a wireless HDTV connectivity throughout the home. It is being driven by AMIMON, Hitachi Ltd., LG Electronics, Motorola, Samsung Group, Sharp Corporation and Sony.[1]
WHDI enables delivery of uncompressed high-definition video over a wireless radio channel, allowing consumers to connect any source in the home to any display device.
Versions
The WHDI 1.0 standard specification was finalized in December 2009.[2][3] Sharp Corporation will be one of the first companies to roll out wireless HDTVs.[4][5] AT CES 2010 LG Electronics announced a WHDI wireless HDTV product line.[6][7]
In June 2010, WHDI announced an update to WHDI 1.0 which allows support for stereoscopic 3D, and WHDI 2.0 specification to be completed in Q2 2011.[8]
WHDI 3D update due in Q4 2010 will allow support for 3D formats defined in HDMI 1.4a specification
WHDI 2.0 will increase available bandwidth even further, allowing additional 3D formats such as "dual 1080p60", and support for 4K x 2K resolutions.
Technology
WHDI 1.0 provides a high-quality, uncompressed wireless link which supports data rates of up to 3Gbit/s (allowing 1080p - HD video) in a 40 MHz channel, and data rates of up to 1.5Gbit/s (allowing 1080i and 720p - HD video) in a single 20 MHz channel of the 5 GHz unlicensed band, conforming to FCC regulations and worldwide 5 GHz spectrum regulations. Range is beyond 100 feet (30 m), through walls, and latency is less than one millisecond.[9]
