  2. RC-5 - Wikipedia

    en.wikipedia.org/wiki/RC-5

    Each bit of the RC-5 code word contains 32 carrier pulses, and an equal duration of silence, so the bit time is 64×27.778 μs = 1.778 ms, and the 14 symbols (bits) of a complete RC-5 code word take 24.889 ms to transmit. The code word is repeated every 113.778 ms (4096 ÷ 36 kHz) as long as a key remains pressed.

    For example, a :30 second spot might have had a code of XECA1263, while the same commercial in a shortened :20 or :15 version (or in a different language such as Spanish) might have had a slightly different code of XECA1264. The ISCI code was unique to each individual commercial. The slightest change to an ad led to the use of another code.
