Wireless Home Digital Interface (WHDI) is a consumer electronic specification for a wireless HDTV connectivity throughout the home. WHDI enables delivery of uncompressed high-definition digital video over a wireless radio channel connecting any video source ( computers , mobile phones , Blu-ray players etc.) to any compatible display device .
Wireless HDMI is the wireless transmission of high-definition audio and video signals between devices, using unlicensed radio frequencies like 5 GHz, 60 GHz, or 190 GHz. This technology eliminates the need for an HDMI cable , allowing users to transmit signals wirelessly between the component device and the display device.
First-generation implementation achieves data rates from 4 Gbit/s, but the core technology allows theoretical data rates as high as 25 Gbit/s (compared to 10.2 Gbit/s for HDMI 1.3 and 21.6 Gbit/s for DisplayPort 1.2), permitting WirelessHD to scale to higher resolutions, color depth, and range.
twin DVI (for two monitors via an adapter cable) Apple Display Connector: Combines DVI, USB, and power. HDMI connector plugs (male): Type D (Micro), Type C (Mini), and Type A. High-Definition Multimedia Interface (HDMI) High definition digital video devices (HDMI protocol)
Any DVI-to-HDMI adapter can function as an HDMI-to-DVI adapter (and vice versa). [56] Typically, the only limitation is the gender of the adapter's connectors and the gender of the cables and sockets it is used with. Features specific to HDMI, such as remote-control and audio transport, are not available in devices that use legacy DVI-D signalling.
Supports wireless transmission of audio/visual data Enables wireless DisplayPort and other display interfaces that include the High-bandwidth Digital Content Protection 2.0 feature. Offers key A/V applications, such as the transmission of lightly compressed or uncompressed video from a computer or digital camera to an HDTV, monitor or projector
The latest model, the 6th generation, supports 802.11ac networking in addition to older standards. Versions of the same system with a built-in network-accessible hard drive are known as the AirPort Time Capsule. Apple discontinued developing its lineup of wireless routers in 2016, but as of 2023 continues limited hardware and software support.
HDMI lacks VGA compatibility and does not include analog signals. DVI is limited to the RGB color model while HDMI also supports YCbCr 4:4:4 and YCbCr 4:2:2 color spaces, which are generally not used for computer graphics. In addition to digital video, HDMI supports the transport of packets used for digital audio.
