What is WHDI?- Wireless Home Digital Interface

Wireless Home Digital Interface ( WHDI ) is a consumer electronic specification for a wireless HDTV connectivity throughout the home, it revolutionizes the home multimedia experience by wirelessly delivering interactive HD Video from any device to any display.

WHDI Consortium

   WHDI Consortium was formed by Amimon, Hitachi, Motorola, Samsung, Sharp, Sony and LG Electronics in 2008. Its goal is to “ send video audio to all display devices wirelessly”. Not only the TV adapter, but also consider using WHDI embedded in a projector for meetings.

They are very responsible, developing the WHDI Standards, public education and promotion as well as the certification and compliance programmers required to ensure interoperability is maintained between all equipment whatever the manufacturer.

 Since then many companies joined WHDI as Adaptors and Contributors, now its members are all over the world.

WHDI Technology

   WHDI setting a new standard for wireless HD Video connection, provide a high-quality, uncompressed wireless connection. It using MIMO technology and OFDM modulation to come true the transfer rate up to 3Gbps. WHDI work at 4.9GHz-5.87GHz frequency bandwidth, 20MHz or 40MHz Channel, conform to worldwide 5GHz spectrum regulations, the range is within 30 meters, through walls, and latency is less than 1ms.
