Video sender

Most video sender systems will consist of three separate components, a transmitter, a receiver and a remote control relay (also known as a magic eye or IR blaster).

ASK/OOK schemes such as RC5 and RC6 work best over the RF link as the receiver uses a data slicer and AGC designed for ASK/OOK with Manchester encoding.

Within the video sender market, these techniques allow for a wireless signal to be transmitted with much less chance of interference from, and to, local Wi-Fi networks.

By also employing externally mounted antennas, operational ranges in excess 2,000 metres (6,600 ft) (clear line-of-sight) have been achieved and several such models are sold under the Digi-Sender brand.

These include technologies that allow for mobile device screen-mirroring, such as Miracast and AirPlay, as well as media streaming features such as DLNA.

Ultra-wideband is a technology for transmitting information spread over a large bandwidth (>500 MHz) and is generally used for short-range applications (typically 10 metres (33 ft) or less) where a simple link is required from the source device to a monitor or television.

This provides similar benefits to a wireless video sender i.e. no additional cabling, as well as the ability to transmit in high-definition and even ultra-high-definition resolutions.

In 2010 a new standard for cabled applications was released called HDBaseT a consumer electronic (CE) and commercial connectivity technology for transmission of uncompressed high-definition video (HD), audio, power, home networking, Ethernet, USB, and some control signals, over a common category (Cat5e or above) cable with a standard connector (RJ45).

The regulator is the Federal Communications Commission (FCC) in the United States who are responsible for the efficient use of radio bandwidth.
