some questiones about LDPC

[tarkyss]

How many bits can be corrected when LDPC decoding at most?
Actually, my question is how many bits can be changed when LDPC decoding at most, including the case of decode error.
It can be calculated by Dmin - 1 / 2 as the same as normal ECC ?
It seems the definition of Dmin of LDPC different with normal ECC?
who can explain it for me?
thanks
