(Comment) : If the SQOK of the subcode Q data is
“
H
”
, the subcode data is output to SQDT according to the
SQCK signal.
If the SQOK is
“
L
”
, it is output to SQDT with
“
L
”
.
VCOI, SBDT, SBCK Timing Chart.
Figure 10. Timing Chart of Subcode Data Output
(1) : After PBFR becomes negative edge, SBCK becomes
“
L
”
for about 10 msec.
(2) : If S0S1 is
“
L
”
, subcode P is output, and if
“
H
”
, S0S1 is output.
(3) : If a period of VCOI is
“
T
”
, the width of (3) is 4T.
(4) : If the pulse input to the SBCK terminal is over seven, subcode data (P, Q, R, S, T, U, V, W) is repeated.
ECC (ERROR CORRECTION CODE) BLOCK
The function of the ECC block is to recover damaged data to some extent when data on a disc is damaged. By
using the CIRC (Cross Interleaved Reed-Solomon Code), 2-Error correction is performed for C1 (32, 28) and 4-
erasure correction is performed for C2 (28, 24).
ECC is performed by the unit of one symbol of eight bits. In correcting C1, a C1 pointer is generated, and in
correcting C2, the C2 pointer is generated. C1, C2 pointers send error information to the data which ECC is given.
After correcting C2, against uncorrectable data, error data is sent to display by outputting a C2 FLAG.
This information data is input to the interpolator block in order to handle error data.
The monitoring flow for error correction is available through FLAG1 ~ FLAG5 terminals.
