Introduction

About the Picture-in-Picture Processors

The Extron PIP 422 is a 2-input video picture-in-picture processor. The PIP 444 is a
4-input picture-in-picture video processor. The processors accept up to two
(PIP 422) or four (PIP 444) composite video, S-video, or component video input
signals. Both units can output the signals simultaneously to three displays: one
composite, one S-video, and one component. Both PIPs feature window effects and
freeze control. The PIP 444 also features genlock capability. Ten (PIP 422) or
twenty (PIP 444) factory presets or user-defined presets save picture number, size,
position, and priority information as well as window text, and border and
background colors.

Features

Inputs — The PIP 422 has two video inputs that can be configured for composite

video, S-video, or component video. The PIP 444 has four video configurable
inputs.

Buffered loop-throughs — Each input is buffered, looped through, and output for

viewing on a local monitor.

Output — The processor has three simultaneous video outputs, one each for

composite video, S-video, and component video. All three outputs can be
configured for NTSC or PAL video.

Picture controls — Picture controls allow you to adjust size, position, brightness/

contrast, color/tint, detail, and zoom for each window.

Window presets — The processor has 10 (PIP 422) or 20 (PIP 444) factory presets

that the user can change to set custom presets. The presets save sizing,
positioning, priority, text, and color information for the windows.

Window effects — These effects enable or disable inputs using either a cut, wipe,

or dissolve effect.

Swap function (PIP 422 only) — A pr ess of a button swaps (exchanges)

configuration settings (size, position and overlay priority) between the two
windows.

Freeze control — Freeze control freezes (locks) selected windows of the current

image.

Remote control — Operate the processor remotely via an optional RS-232/RS-422

control device.

Genlock (PIP 444 only) — Allows seamless switching between inputs by using an

external black burst generator to synchronize devices.

Front panel security lockout (Executive mode) — Locks the picture control and

menu buttons on the front panel to avoid accidental changes to settings.
Input selection, freeze control, and recall of presets are still available while
the processor is locked.

Rack mountability — The 1U high and full rack wide metal enclosure can be

mounted in a rack.

RS-232/RS-422 port — The rear panel RS-232/RS-422 port provides for remote

control of the PIP from a PC or control system. Remote control can be via
either the Extron Windows
Instruction Set
you to perform most of the PIP operations.

Installation

Mounting the Processor

The PIP 422 and PIP 444 are housed in 1U high, 17.4" wide metal enclosures that
are rack- or desk-mountable. The appropriate rack/desk mounting kit (#70-077-03)
is included with the processor. The processor may also be surface-mounted under
a table, desk, or podium, or on a wall, using an optional Extron 1U enclosure
under-desk mounting kit (#70-222-01).

UL requirements

The following Underwriters Laboratories (UL) requirements pertain to the
installation of the PIP into a rack (figure 2-1) or furniture (figure 2-3.

1. Elevated operating ambient temperature — If installed in a closed or multi-

unit rack assembly, the operating ambient temperature of the rack
environment may be greater than room ambient. Therefore, consider
installing the equipment in an environment compatible with the maximum
ambient temperature (Tma) specified by the manufacturer.

2. Reduced air flow — Installation of the equipment in a rack should be such

that the amount of air flow required for safe operation of the equipment is not
compromised.

3.

Mechanical loading — Mounting of the equipment in the rack should be such

that a hazardous condition is not achieved due to uneven mechanical loading.

4. Circuit overloading — Consideration should be given to the connection of

the equipment to the supply circuit and the effect that overloading of the
circuits might have on overcurrent protection and supply wiring.
Appropriate consideration of equipment nameplate ratings should be used
when addressing this concern.

5. Reliable earthing (grounding) — Reliable earthing of rack-mounted

equipment should be maintained. Particular attention should be given to
supply connections other than direct connections to the branch circuit (e.g.
use of power strips.

Rack mounting

Rack mount the PIP as follows:

1. Remove the feet from the underside of the PIP, if installed.

2. Attach the supplied rack mounting brackets to the processor with the eight

provided #8 machine screws (figure 2-1).

The table/wall mounting brackets extend approximately 1/4" (6.4 mm) above the
top surface of the processor enclosure. This design allows for an air space between
the enclosure and the surface to which it is mounted. Table or wall mount the
PIP as follows:

1. Remove the feet from the underside of the PIP, if installed.

2. Attach the table/wall mounting brackets to the processor with the eight

provided #8 machine screws (figure 2-1).

3. Hold the processor with the attached brackets against the underside of the

table or other furniture, or against the wall. Mark the location of the screw
holes of the bracket on the mounting surface.

4. Drill 3/32" (2 mm) diameter pilot holes, 1/4" (6.4 mm) deep in the mounting

surface at the marked screw locations.

5. Insert #8 wood screws into the four pilot holes. Tighten each screw into the

mounting surface until just less than 1/4" (6 mm) of the screw’s head
protrudes.

6. Align the mounting screws with the slots in the brackets and place the

processor against the surface, with the screws through the bracket slots.

7. Slide the PIP slightly forward or back, then tighten all four screws to secure

the processor in place.

Setting Up Genlock and Vertical Interval Switching

For vertical interval switching (to allow clean switching between signals from
several devices during the vertical blanking period of each signal), a composite
sync signal can be applied at the Genlock In connector, and also passed to another
device via the Genlock Out connector.

If the genlock connectors are used only for vertical interval switching, no horizontal
or subcarrier phase adjustments are required.

Genlock setup

Genlock differs from simple vertical interval switching in that an external device (a
black burst generator) generates a reference sync signal for the system, and every
device that uses that signal has its output signal’s horizontal and subcarrier phases
adjusted to exactly match that of the generator, allowing precise timing and full
synchronization. Genlocked systems produce cleaner switches between inputs
than do those without this type of synchronization.

An oscilloscope is required for genlock setup, and a vectorscope is recommended.
Waveform monitors of types other than a vectorscope may give the appearance that
timing is adjusted correctly when it is 180 degrees out of phase, which will result in
incorrect colors or picture artifacts.

All equipment in the system must be powered up and turned on for at least
15 to 20 minutes before genlock setup adjustments can be made and before the
equipment is used in a genlocked application.

To synchronize the PIP’s video output with a genlock signal, follow these steps:

1. Power up and turn on all the devices that will use the genlock signal.

The devices must be on for at least 15 to 20 minutes before proceeding
with any adjustments.

2. Connect the active timing source signal to the Genlock In connector on

the rear panel.

3. Connect the video input devices to the PIP, as described previously in

this chapter.

4. Connect the oscilloscope (“scope”) probe A to the Genlock Out connector.

This will provide the scope’s reference signal. In order to avoid altering
the genlock signal, use the cabling configuration that will be used in the
installation. Either connect the genlock signal cable from the scope to the
next device in the system to be timed, or provide 75 ohm termination at
the scope’s genlock output.

5. Connect scope probe B to the PIP’s composite video output connector.

6. Using the instructions for the scope you are using, set the scope to view

the signals’ horizontal phases. Adjust the horizontal phase until there is
no (0°) difference between the composite video output’s horizontal sync
phase and the genlock signal’s horizontal phase. See “Genlock
configuration menu (PIP 444 only)” in chapter 3, “Operation”, and
“Oscilloscope displays” later in this chapter for details on adjusting the
horizontal phase.

7. Set the scope to view the subcarrier signals. Adjust the subcarrier phase

until there is a zero phase difference between the genlock signal and the
NTSC/PAL output. See “Genlock configuration menu (PIP 444 only)” in
chapter 3, “Operation”, and “Oscilloscope displays” later in this chapter
for details on adjusting the color subcarrier phase.

Oscilloscope displays

What you see on the oscilloscope while adjusting the PIP to match the genlock
signal depends on the type of signal used, the type of oscilloscope, and the
procedure the scope requires. This section shows some examples of oscilloscope
displays.

Figure 2-7 below shows the genlock input signal (top) and an out-of-alignment
NTSC composite sync output signal (bottom) displayed on a waveform monitor to
check for alignment. When the phases are aligned, the wave peaks on the bottom
waveform should line up with those in the reference signal above it.

With this method there is no way to know if the signals are 180º out of phase. A
delayed sweep on a time-based scope would allow a more accurate display of the
input and output signal phase relationships.

to each device, and repeat this procedure.

Figure 2-7 — Superimposed waveforms

A vectorscope is more accurate than a waveform monitor. Figure 2-8 shows an
example of a vectorscope display when the horizontal phase is adjusted to align it
with the burst (genlock) vector. Adjust the horizontal phase by accessing the
Genlock configuration menu and rotating either of the Adjust knobs until the
difference between the two vectors is 0º (see “Genlock configuration menu (PIP 444
only)” in chapter 3, “Operation” for more information). This example shows black
burst only (with no color). The burst vector is pointing to the left from the center.
