The following bitmaps are waveforms measured with a digital oscilloscope. The signals were transmitted with a sony remote control
| SONY infrared remote protocol |
| The Sony remote control is based on the Pulse-Width signal coding scheme. | |
| The code exists of 12 bits sent on a 40kHz carrier wave. The code starts with a header of 2,4ms or | |
| 4 times T where T is 600µS. The header is followed by 7 command bits and 5 adres bits. | |
| The address and commands exists of logical ones and zeros. A logical one is formed by | |
| a space of 600µS or 1T and a pulse of 1200 µS or 2T. A logical zero is formed by a space of 600 µS | |
| and pulse of 600µS. | |
| The space between 2 transmitted codes when a button is being pressed is 40mS | |
| The bits are transmitted least significant bits first. The total length of a bitstream is always 45ms. | |
