context_page_description: A video sender is a device for transmitting domestic audio and video signals wirelessly from one location to another. It is most commonly used for sending the output of a source device, such as a satellite television decoder, to a television in another part of a property and provides an alternative to cable installations.
  A wide range of video sender technologies exist, including analogue wireless, digital wireless and digital wired. Other, less common, technologies also exist, such as those that use existing Ethernet networks.
  Video senders have been a frequent cause of RF interference, particularly with car key fobs.
context_section_description: Digital video senders are quickly becoming the most popular solution and combine the use of a system on chip (used for audio and video encoding/decoding) with a means of transmitting the signal, such as spread-spectrum, Wi-Fi and ultra-wideband.
  Early digital video sender models typically transmitted in DVD quality, but more recent models are capable of achieving 720p and 1080p high-definition resolutions.
