The signals are then converted back to analog and
output at the YUV outputs of the IC.
The PIP-Y signal is applied directly to pin 7 of the
VCJ. The PIP UV signals are selected by IC2Y01
and are directed to pins 10 and 8 of the VCJ. The
YUV-SW signal from the Control circuitry is LOW
selecting the PIP UV signals.
The FBL (Fast Blank Switch) signal from pin 68 of
IC6P01 is applied to the YUV-SW input of the VCJ.
This signal times the insertion of the PIP signals into
the main signals.
Side by Side Mode (VZ7+ only)
The internal circuitry in IC6P01 converts both the
main and sub picture YUV signals to digital, and
writes them into memory. The memory is then read
in the sequence required to produce the signal for
the Side by Side pictures. The signals are converted
back to analog and directed out the YUV outputs of
the IC.
IC6Y01 directs the POP-Y signal to pin 63 of the
VCJ. The signal selection of IC6Y01 is controlled
by the PIP-SW line from the Control circuitry. A
HIGH selects the POP-Y signal. The PIP-SW line
also drives the YUV-SW input of the VCJ HIGH,
selecting pins 10 and 8 as the U and V inputs.
DVD Component as the Main Picture Source
The YUV-SW line goes HIGH selecting the DVD
UV signals and via R6P81 drives pin 5 of the VCJ
HIGH, enabling the UV input at pins 10 and 8. The
PIP-SW line is held LOW, so the logic at pin 2 of
IC6Y01 does not go HIGH from the YUV-SW line.
