STD strokes

STD OMR codes use standard strokes, i.e. each stroke position in the code has a predefined meaning.

Stroke position	Value	Explanation
1	1	Synchronization
2	0	Space, double row-distance
3	1	Read control
4	Seq1	1st bit of the sequence
5	Seq2	2nd bit of the sequence
6	Seq4	3rd bit of the sequence
7	Seq8	4th bit of the sequence
8	notlast	1 – if the sheet is not the last one. 0 – if the sheet is the last one.
9	last	1 – if the sheet is the last one. 0 – if the sheet is not the last one.
10	0	Call slave – this stroke is not supported by StreamServe, always 0.
11	Ins1	1st bit of insert mask
12	Ins2	2nd bit of the insert mask
13	Ins3	3rd bit of the insert mask
14	Ins4	4th bit of the insert mask
15	Parity	1 – if the sum of strokes with value 1 is even 0 – if the sum of strokes with value 1 is odd.
Only for STDE and STDHE
16	1	Extra bit at the end.
