Introduction

About the Picture-in-Picture Processors

Features

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 press 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®-based control program or the Extron Simple Instruction Set™ (SIS™). The SIS is a set of simple ASCII commands that allow you to perform most of the PIP operations.

Setting Up Genlock and Vertical Interval Switching

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).

Figure 2-1 — Mounting a PIP

1. Insert the processor into the rack, align the holes in the mounting bracket with those of the rack.

2. Secure the processor to the rack using the supplied machine screws.

Table or wall mounting

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.

Through-desk mounting

Mount the PIP through a desk or podium as follows:

1. Remove the feet from the underside of the PIP, if installed.
2. Attach the supplied mounting brackets to the processor with the machine screws provided (figure 2-1).
3. Cut the proper sized hole in the mounting surface (figure 2-2).

Figure 2-5 — Video input and buffered loop-through connections

NOTE

Connect only one video format to each input.

You must configure each input to identify the connected video format. See chapter 3, "Operation".

③ Input loop-through (bottom) connectors — If desired, connect local monitors to these female BNC connectors. The processor buffers the video input and loops it out on these connectors.

NOTE

The processor does not alter the video signal between the input and the buffered loop-through in any way. The processor's buffered loop-through output is in the same format as the input.

④ Output connectors — Connect a component video, S-video, and/or composite video display device to these BNC connectors. Figure 2-6 shows how to connect the various video formats.

Figure 2-6 — Video output connections

NOTE

The component video, S-video, and composite video outputs are all active simultaneously, so multiple displays can be connected.

⑤ Genlock connectors (PIP 444 only) —

In(put) connector — Connect an external black burst signal to this BNC connector for genlocking the video signal in broadcast or other sync-critical applications.

Out(put) connector — Connect any downstream equipment that requires genlocking to this BNC connector to route the black burst signal throughout the system in broadcast or other sync-critical applications.

NOTE

If no device is connected to the output, terminate the Genlock output with the included 75-ohm terminator.

See "Setting Up Genlock and Vertical Interval Switching", on the next page, for detailed Genlock instructions.

⑥ RS-232/RS-422 connector — Connect a host computer or control system to this female 9-pin D connector to allow remote control of the PIP using Extron's Simple Instruction Set ^™ (SIS ^™ ) or control software for Windows ^® . (See Chapter 4, "Remote Control", for more information.)

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.

NOTE 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.

8. View the horizontal phases again. If the phase difference is not zero, repeat steps 6 and 7 until the settings do not change.

9. Once the settings are stable, disconnect the oscilloscope, and reconnect the genlock cables.
10. Check the display(s) for proper colors and for undesirable artifacts in the image(s). Make adjustments as necessary.
11. If other PIPs are part of this genlock daisy chain, connect the oscilloscope to each device, and repeat this procedure.

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 180^ 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.

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 0^ (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.

Circular gauge or dial with numerical markings from 0 to 360, no readable text or symbols beyond the scale markings.

Figure 2-9 below shows an example of a view of a vectorscope during adjustment of the color subcarrier phase (SC/H). The subcarrier phase should be aligned to 0^ (indicated in the figure by the triangle).

Power-on Indications

Power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks all of the front panel LEDs and then lights only the LEDs for the inputs previously selected for the display. The self-test also displays the model name, part number, and the firmware version in the LCD display. After approximately 2 seconds, the LCD reverts to its default display cycle, alternating among several displays; one for each input that shows that input's configuration, and the last showing the selected output standard (figure 3-3). An error-free power up self-test sequence leaves all of the LEDs, with the exception of the selected inputs' LED(s), off and the LCD displaying the default display cycle.

The selected inputs and their size and position on the display, the picture adjustments, and other current settings are saved in nonvolatile memory. When power is applied, the latest configuration is retrieved.

NOTE

On figure 3-3 and all other flowcharts in this chapter, solid lines indicate screen changes initiated by the operator. Dashed lines indicate screen changes that are the result of a timeout function.

Remote Control

Simple Instruction Set Control

Control Software for Windows®

The PIP's RS-232/422 port is used to connect to a host or external controlling device, such as a computer or control system, which can generate the proper command codes and recognize the processor's responses.

NOTE The cable used to connect the RS-232/RS-422 port to a computer or control system may need to be modified by removing pins or cutting wires. If unneeded pins are connected, the processor may hang up. See chapter 2, "Installation", for more information on wiring the connectors.

The RS-232/RS-422 connector is a 9-pin D female (figure 4-1). The default protocol is RS-232, 9600 baud, 8-bit, 1 stop bit, no parity, and no flow control.

NOTE See "Selecting the baud rate and RS-232/RS-422 protocol" in chapter 3, "Operation", to change the protocol.

Simple Instruction Set Control

Host-to-PIP communications

The PIP 444 and PIP 422 accept SISTM (Simple Instruction SetTM) commands through the RS-232/RS-422 port. SIS commands consist of one or more characters per command field. They do not require any special characters to begin or end the command character sequence. Each response to an SIS command ends with a carriage return and a line feed (CR/LF = ) which signals the end of the response character string. A string is one or more characters.

PIP-initiated messages

(C) Copyright 2005, Extron Electronics, PIP 422 (444), V. x.xx

Error responses

When the PIP receives a valid SIS command, it executes the command and sends a response to the host device. If the processor is unable to execute the command because the command is invalid or contains invalid parameters, it returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (too large)

E09 — Invalid function number (too large)

E10 — Invalid command

E11 — Invalid preset

E13 — Invalid value (out of range)

E23 — Checksum error

Control Software for Windows®

The Windows-based Extron PIP 422 & 444 Control Program, which communicates with the processor via the RS-232/RS-422 port, provides an easy way to configure and operate the PIP. The program is compatible with Windows 2000 and Windows XP.

Installing the software

The program is contained on the Extron Software Products CD-ROM, disk B. Install the software as follows:

NOTE

For full functionality, install both of the following programs:

• The PIP 422 & 444 Control Program
• The Firmware Loader

1. Insert the CD-ROM into the drive. The installation program should start automatically. If it does not self-start, run Launch.exe from the CD.

The Extron software CD window appears (figure 4-2).

Figure 4-2 — Software CD window

1. Click the Software tab (figure 4-2).
2. Scroll to the desired program and click Install (figure 4-3).

Figure 4-3 — Software installation

1. Follow the on-screen instructions. By default, the Windows installation of the PIP 422 & 444 Control Program creates a C:\Program Files\Extron\PIP 422 & 444 directory, and it places four icons into a group folder named "Extron Electronics\PIP 422 & 444." The four installed icons are:

2. PIP 422 & 444

3. PIP 422 & 444 Help
4. Check for PIP 422 & 444 Update
5. Uninstall PIP 422 & 444

Starting the control program

To run the software:

1. Click Start > Programs > Extron Electronics > PIP 422 & 444 > PIP 422 & 444. The Communication Connection Settings window appears (figure 4-4).

PIP 422 & 444

Figure 4-4 — Communication Connection Settings window

1. Select the comm port that is connected to the PIP's remote connector and the baud rate at which the PIP is operating. Click Connect.

NOTE

If you don't want to take this step every time, select the Automatically connect with this setting when it starts up next time check box.

The PIP 422 & 444 program window appears (figure 4-5).

Figure 4-5 — PIP 422 & 444 program window

The program window is divided into three areas: a tool bar on the top of the window, a graphic area on the right side of the window, and a controls area on the left side of the window.

Tool bar

The tool bar (figure 4-6) provides a number of buttons that provide shortcuts for common tasks such as connecting and disconnecting, saving and recalling the current configuration, uploading new firmware, and system help. Saving and restoring the current configuration and uploading firmware are covered in more detail below.

Figure 4-6 — Tool bar

Open and Save buttons

Any changes that you make to the display, including size, position, border and background color, and selected inputs, can be saved in a file with the extension *.pip. To save the values, click the Save button shown at right. If you haven't already saved the values before, the program prompts you to name the file.

To restore the settings from the *.pip file, click the Open button, shown at right, and select the desired file.

Data trace button

The data trace button calls the trace log window (figure 4-7), which shows the serial communications, in ASCII and Hex, between the controller and the PIP. Reference to this window can be helpful when writing your own control scripts.

Figure 4-7 — Trace log window

Upgrade firmware button

The firmware upgrade utility provides a way to replace the firmware that is coded on the processor's control board without taking the processor out of service.

NOTE Upgrading the firmware does not overwrite the settings or presets.

Update the processor firmware as follows:

1. Start the PIP 422 & 444 control program and connect to the processor. See "Starting the control program" in this chapter, starting on page 4-10.

2. Visit the Extron web site (www.extron.com), click the Download tab, and select either the PIP 422 or PIP 444. Select the appropriate firmware file to download and copy it to your computer. Note the folder to which you save the firmware file.

3. Click the update firmware button (figure 4-8). The Extron Firmware Loader appears.

Figure 4-8 — Open window

4a. Click Browse. The open file window appears.
4b. Navigate to the folder where you saved the firmware upgrade file. Select the file. The Firmware Loader returns to the top.

NOTE Ensure that the firmware upgrade is for the PIP.

NOTE Valid PIP firmware files must have the file extension ".pkg". Any other file extension is not a firmware upgrade for your PIP.

4c. Click Upload. The File Loader reports, "This process could take several minutes. Please wait..." and then displays a scroll bar that shows the status of the upload.

4c. When the Firmware Loader reports, "Transfer complete!", click Exit.

NOTE If the firmware loader utility exits before the status bar has progressed completely across the indicator window, try using a control cable with only pins 2, 3, and 5 connected. If necessary, modify the cable by removing pins or cutting wires.

Check for software updates button

This button forces the controlling computer, if connected to the Internet, to check the Extron Web site to see if any firmware update (firmware of a version newer than that installed in the PIP) is available for the PIP. If a newer firmware version is available, the program prompts you to download and install the firmware.

Graphic area

The graphic area (figure 4-9) represents the PIP's video output and the associated four (PIP 444) or two (PIP 422) picture-in-picture windows.

Figure 4-9 — Graphic area

• To resize a window, click an anchor point ( ■) and drag it to resize the window.
• To move a window, click in the desired window and drag it to the new location.

NOTE To retain the aspect ratio when resizing, select the Lock Aspect Ratio checkbox.

NOTE If you have dragged a window so far out of the picture that you have "lost" it, click View > Expanded View to show the entire horizontal and vertical video stream.

• Right click any window area to bring up the image area for the associated window or to execute the center image function.
• Right click outside of the window area to change the border color, background color, or to change the text position and style.
• Double-click any window to activate the image view for that window (indicated in dark blue). To return to the window view, double-click the image again.

Controls area

The controls area, figure 4-10, consists of four tabs, Control, Preset, Picture, and Advanced, that allow you to perform many of the same functions as the PIP's front panel.
