/* The G.I. Cable protocol is is used by many Motorola brand cable boxes manufactured by
 * General Instruments. The IRP notation for this protocol is 
 * "{38.7k,490}<1,-4.5|1,-9>(18,-9,F:8,D:4,C:4,1,-84,(18,-4.5,1,-178)*) {C = -(D + F:4 + F:4:4)}"
 * It is a 16-bit code which uses an unusual "ditto" repeat sequence similar to NEC.
 * In fact it is so similar that IRLib generally not distinguish between the two.
 * The header timing for G.I. Cable ditto is 8820,1960 and for NEC is 9024,2256
 * If you are using both protocols and you receive an NEC ditto immediately after 
 * receiving a G.I.Cable then you should presume it is a G.I.Cable and vice versa.
