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 .
Miracast is "effectively a wireless HDMI cable, copying everything from one screen to another using the H.264 codec and its own digital rights management (DRM) layer emulating the HDMI system". The Wi-Fi Alliance suggested that Miracast could also be used by a set-top box wanting to stream content to a TV or tablet.
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.
Wi-Fi over Coax is a technology for extending and distributing Wi-Fi signals via coaxial cables.As an in-building wireless solution, Wi-Fi over Coax can make use of existing or new cabling with native impedance of 50 Ω shared by a Wi-Fi access point, cabling run, and antenna.
A converter box takes the digital signal from the antenna and outputs composite video (for SD TVs) or HDMI (for HD TVs). A RF/antenna output, if present on a converter box, is usually just a passthrough ("LOOP OUT" which does not provide the box's output signal, but only provides the raw antenna input signal to watch analog channels via a TV ...
The 60 GHz band usually requires line of sight between transmitter and receiver, and the WirelessHD specification ameliorates this limitation through the use of beam forming at the receiver and transmitter antennas to increase the signal's effective radiated power, find the best path, and utilise wall reflections.

A typical modern set-top box, along with its remote control - pictured here a digital terrestrial TV receiver by TEAC. A set-top box (STB), also known as a cable box, receiver, or simply box, and historically television decoder or a converter, [1] is an information appliance device that generally contains a TV tuner input and displays output to a television set, turning the source signal into ...
The TV set usually connected via a HDMI (or SCART) cable works as a multimedia monitor. The device may connect to a home audio system either via TOSLINK or Bluetooth. The box can be accessed with terminal emulation protocol telnet, ssh, or via FTP. The OpenWebif module implements a web server that allows control of the box from a PC using a web ...
