We select "10" in example data.
10
In next 3 bit, we put mask pattern indicator which is selected in previous section.
10 011
We put error correcting data which is Bose-Chaudhuri-Hocquenghem(BCH)(15,5) in right 10 bit.
First, polynomial F(x) which coefficients are above 5 bit and x10 times is divided by below G(x).
G(x)=x10+x8+x5+x4+x2+x+1
In example data,5 bit data is "10011" and F(x) is below. F(x)=x14+x11+x10
divide by G(x)....
Remainder R(x)=x8+x7+x6+x
So we get result as 10011 0111000010
Finally,we calculate exclusive logical sum "101010000010010" and above result to avoid that result data is not all 0.
Format information is "001100111010000".
We put results in number of below figure. (left side of bit data is upper bit[14]. )
