Infrared Remote Control Signal Decoding by rudra is a document available to read on EtoBox.

This document provides an overview of decoding infrared remote control signals using a Microchip 16C57 microcontroller. It explains that the NEC 6121 format uses pulse width timing of 2.24ms for a data "1" and 1.12ms for a data "0". Common modulating frequencies for infrared remote controls are 38kHz and 40kHz, and the receiver must use the same demodulating frequency. Interference from devices like fluorescent lights may prevent the receiver from detecting signals, so confirming functionality by switching
