ECC FEATURE

 Euclid's Algorithm Use.

 Same circuits are used for DVD and CD.

(1) For DVD (primitive polynomial : x8 + x4 + x3 + x2 + 1)

: Error correction capability for DVD Data.

→ PI (182, 172, 11) CODE : 5 error correction / 10 errata correction

→ PO (208, 192, 17) CODE : 8 error correction / 16 errata correction

 33.8688 MHz Clock : at 1X operation (PI+PO+PI)/1 EFM BLOCK satisfied

->Basic operation

(2) For CD (primitive polynomial : x8 + x4 + x3 + x2 + 1)
