The current code generates 8 oob sections:
|
|
S1 1-5
|
|
ECC 6-8
|
|
S2 9-15
|
|
S3 16-21
|
|
ECC 22-24
|
|
S4 25-31
|
|
S5 32-37
|
|
ECC 38-40
|
|
S6 41-47
|
|
S7 48-53
|
|
ECC 54-56
|
|
S8 57-63
|
|
|
|
Change it by merging continuous sections:
|
|
S1 1-5
|
|
ECC 6-8
|
|
S2 9-21
|
|
ECC 22-24
|
|
S3 25-37
|
|
ECC 38-40
|
|
S4 41-53
|
|
ECC 54-56
|
|
S5 57-63
