WHDI (Wireless Home Digital Interface) is a technology standard that has been designed to deliver high quality video and audio content within a multimedia network in the house. WHDI uses the 5 GHz frequency band to wirelessly stream interactive HD video and audio from any device to a display unit over an effective range of 100 - 150 feet with video rates of up to 1080p. This technology provides consumers with flexibility and convenience to connect HDTVs wirelessly to video sources such as mobile phones, iPADs, playstations, notebooks, set-top boxes etc.

WHDI provides wireless connectivity for a wide range of media-centric devices like televisions, media players, audio devices, recorders, etc. in the home.

WHDI Standards

WHDI 1.0

  • It supports data rates of up to 3 Gbit/s in a 40 MHz channel and up to 1.5 Gbit/s in a single 20 MHz channel. 
  • It enables full 1080p/60 Hz video streaming beyond 100 feet (30 m), through walls. 

WHDI 2.0

  • It supports the next-generation 1080p 60 Hz x 2 3D format.
  • It also supports 2K x 4K HD format with four times the resolution of 1080p.
  • Provide support for stereoscopic 3D images.

The WHDI Consortium, the organization who has created this standard was supported by leading consumer electronic companies like Hitachi Ltd., LG, Samsung Group, Motorola, Sharp Corporation and Sony. The WHDI Consortium was founded in 2008 and was active till 2012. However the website for this consortium is no longer operational. This could mean that this standard is no longer supported by companies. Post 2012, a number of other technologies and standards were developed for streaming HD Video and WHDI seems to no longer be active/supported.
