This article explores WHDI (Wireless Home Digital Interface) technology, its core principles, and how it facilitates wireless HDTV connectivity. We’ll also clarify the differences between WHDI and WirelessHD.
WHDI, short for Wireless Home Digital Interface, is a consumer electronics specification conceived to handle wireless HDTV connections between various devices within homes or businesses. Essentially, it allows for the delivery of uncompressed HD digital video over an RF channel, linking video source devices with compatible display devices.
The WHDI Consortium champions the standardization and adoption of WHDI-based consumer products. Prominent members of this consortium include industry giants like Hitachi Ltd., Motorola, Sharp, Sony, Samsung, and LG.
