The receiver records sampled durations, tracks the gap before the frame separately, and can compensate timing distortion introduced by a demodulating IR receiver. A transmitter, by contrast, expects an array that starts with the first mark and alternates mark and space durations.</p> <p>That boundary matters for AC remotes because their frames can be long and are frequently replayed as RAW data when no protocol-specific encoder is available.</p>
