This video covers the NEC family of protocols, which are widely used in typical consumer IR remote control devices, and explains how the 38 kHz carrier wave is used to encode a binary signal.

It supports several input and display devices such as infrared remote controls, LCD displays, network connections, and serial keypads.

As AGC3 devices, the receivers are optimized for noisy environments and short burst codes. The TSOP313, TSOP323, TSOP343, TSOP383, and TSOP393 series of ultra-noise-resistant AGC3 IR remote control ...
