INTERPOLATION / MUTE BLOCK
Interpolator
When a burst error occurs on a disc, sometimes the data can
’
t be corrected even if an ECC process is performed.
The interpolator block revises data by using a C2 pointer output through the ECC block.The data input to a data
bus is input to the left and right channel, respectively, in the order of the lower 8-bit and the upper 8-bit.
A pre-hold method is taken when a C2 pointer is
“
H
”
continuously. In case of a single error, an everage
interpolation method is carried out with the range of the data before and after an error happens.
When LRCH signal during one LRCH cycle is
“
L
”
, R-CH data is output, L-CH data is output when the check is
“
H
”
.

Mute and Attenuation
By using a mute terminal and the ATTM signal of the CNTL-S register, audio data is muted or attenuated.There are
two kinds of mute: zero-cross muting and muting
A. Zero-Cross Muting
The audio data is muted, after ZCMT of CNTL-Z register goes to
“
H
”
. In that case the mute is
“
H
”
and the upper 6-
bit of audio data became all
“
L
”
or
“
H
”
.
B. Muting
The audio data is muted when ZCMT of the CNTL-Z register is
“
L
”
and the mute terminal is
“
H
”
.
C. Attenuation
The signal attenuation occurs by the means of the ATTM of the CNTL-Z register, and the mute signal as shown the
following,.
