Generalnt : long paquet de 1 pour stabilisation recepteur sur niveau
------------------------------------------------------------
Protocole courant

2 sortes de paquets :
 - normal : touche appuyee = AGC pulsr + 50 info bit. 1 bit = 0.5*bit + 0.5*0(RAZ)
 - repeat packet = AGC pulse + 1 bit stop

Normal
 AGC pulse = 9.15 ms * 1
 Pause = 4.33 ms * 0
 data bit = 750 us * ?
 stop bit = 375 us * 0
Repeat packet
 AGC pulse = 9.15ms * 1
 Pause = 2.10ms * 0
 stop bit = 750us * 1
 -attente suivant = 38.6ms * 0

------------------------------------------------------------
Protocole Sony

12 bits = 5bit device + 7bit command (LeastSignificantBitsfirst)
AGC = 2.4 (ou 9.15ms ???)
1 bit = 600us*0 + (600us * 1 =Bit0 || 1200us * 1 =Bit1)
Total = 45ms

-------------------------------------------------------------
Protocol Japanese Format (=Toshiba, =Pioneer, !=RCA)

Preambule : 8ms * 1 + 4ms * 0
1Part : 16bits = 8 bits DC (Device Control) + 8 bits NOT DC
2Part : 16bits = 8 bits FC (Function Code) + 8 bits NOT FC

1bit = 0.6ms * 1 + (0.4ms * 0 = Bit0 || 1.2ms = Bit1)
! Least Significant Bit first.

Debut : Long MARK pulse suivi de long SPACE pulse
Donnees repetees 2x : le deuxieme est le complement du 1er -> 1 AND 2 -> Pb transmission
Fin : EOT pulse (???)
Data bit = 1 rapide suivi de 0 long (pour 0) et encore plus long pour 1
