2 PW1230(N11)
The major function of PW1230 is to convert the interlaced video signal into line-by-line video signal
so that the picture is clearer and realer and the picture frame becomes finer and smoother. In addition to
this conversion function PW1230 is capable of enhancing the image and can also be used to adjust the
brightness and contrast of the channel. Nevertheless, the brightness and contrast adjustment function of
this TV set is performed by regulating the front end VPC3230. After the digital video signal received by
PW1230 from VPC3230 is deinterlaced, it is output as 24bit digital RGB signal to GPORT of N15 PW113
where it is processed. The output signals as DDCK (CLOCK), DDVS (FIELD SYNCHRONIZING),
DDHS(LINE SYNCHRONIZING), DDEN (ENABLE SIGNAL) are also basic references for the
processing of lower level.
