 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.Analogue wireless video senders can achieve typical operating distances of up to 60 metres (clear line of sight) with DVD quality (720x576) video resolution and stereo audio.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.
