Video/Color & PIP/POP Circuitry
Increased PIP functions in the VZ7+ chassis models
makes a more complex Video/Color signal path. The
above illustration shows the PIP (Picture In Picture)
and added POP (Picture Outside of Picture) features.
Pressing the "PIP/POP" remote button activates the
Side by Side mode, available in VZ7+ models. The
main and sub pictures are compressed horizontally
and displayed Side by Side.
Pressing the "PIP/POP" button a second time acti-
vates the Channel Scan mode. The sub picture source
scans through channels and displays the channels in
three inserts. The current channel is live and the two
previous channels are still pictures.
Pressing "PIP/POP" a third time activates the con-
ventional PIP mode, a single sub picture insert, avail-
able in all VZ7 models. The insert may be moved
using the "Adjust" direction buttons. The "PIP Size"
button allows the user to select any of five sizes for
the single insert picture.

In all of the PIP/POP modes, pressing the "PIP/
POP" button after 10 seconds terminates the PIP
mode.
Familiarity with the Video/Color signal path in the
various PIP/POP modes helps isolate problems to a
specific section of the circuitry. The following lists
key points that are valuable when isolating a prob-
lem.
• In a PIP insert mode, the main picture signal
does not pass through the PIP/POP circuitry.
• In the POP mode, both the main and sub
picture signals are processed in the PIP/POP
circuitry (VZ7+ models only).
• In a PIP insert mode, the sub picture signals
are input to the VCJ at pins 7, 10 and 8.
• In the Side by Side mode, the main Y signal
is input to the VCJ at pin 63, and the UV
color signals are input at pins 10 and 8.
