Genlock and Vertical Interval Switching

Vertical interval switching provides for clean switching between signals from
several devices during the vertical blanking period of each signal. Vertical
interval switching between the VSC and another source with an external
switcher can be achieved by applying a composite sync signal at the Genlock In
connector. The sync signal can also be 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 to allow 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.

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

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.

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 signals to the VSC, 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 VSC’s composite video output connector.

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

the signal’s horizontal phases. Adjust the horizontal phase by rotating
the horizontal Adjust (
this chapter). 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 the “Oscilloscope
displays” section in this chapter.

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

rotating the vertical Adjust (
difference between the genlock signal and the NTSC/PAL output (see
the “Genlock menu” section in this chapter).

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 VSCs 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 VSC 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.

The following diagram shows the genlock input signal (top) and an out-of­alignment 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.

A vectorscope is more accurate than a waveform monitor. The following diagram
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 rotating the Adjust horizontal (

Troubleshooting

The image should appear properly on the screen(s).

If the image does not appear

1. Ensure that all devices are plugged in.

2. Make sure that each device is receiving power.

3. Check the cabling, wiring and grounding, and make adjustments as

needed.

4. Verify that the output configuration is correct for the display being used

(RGBHV, RGBs, RGsB, or component).

5. Verify that the input type is correct (RGB or YUV).

6. To test the system setup and output, substitute a video test generator for the

computer input.

The VSC 900/900D can be remotely controlled via a host computer or other
device (such as a control system) attached to the rear panel RS-232 connector.
The control device (host) can use either the Extron Simple Instruction Set (SIS)
commands or the graphical control program for Windows.

The scan converter uses a protocol of 9600 baud, 1 stop bit, no parity, and no
flow control.

The rear panel RS-232 9-pin D connector has the following pin assignments:

RS-232 Programmer’s Guide

Host-to-scan converter communications

SIS commands consist of one or more characters per field. No special characters
are required to begin or end a command sequence. When the VSC 900/900D
determines that a command is valid, it executes the command and sends a
response to the host device. All responses from the scan converter to the host
end 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.

It is also possible to send several SIS commands back-to-back in sequence.

Video scan converter-initiated messages

When a local event such as a front panel selection or adjustment takes place, the
VSC 900/900D responds by sending a message to the host. No response is
required from the host. The scan converter-initiated messages are listed here
(underlined).

(C) Copyright 2003, Extron Electronics, VSC 900, Vx.xx
The VSC 900/900D sends the copyright message when it first powers on. Vx.xx
is the firmware version number.

X1

C hn
The VSC 900/900D sends this response when an input is switched.

Error responses

When the scan converter receives a valid SIS command, it executes the command
and sends a response to the host device. If the VSC 900/900D is unable to
execute the command because the command is invalid or it contains invalid
parameters, it returns an error response to the host.

The error response codes and their descriptions are as follows:
E01 – Invalid input channel number (the number is too large)

E09 – Invalid function number (the number is too large)
E10 – Invalid command
E13 – Invalid value (the number is out of range/too large).

(where X1 is the input number)

Using the command/response tables

The command/response tables on the next page list valid command ASCII codes,
the scan converter’s responses to the host, and a description of the command’s
function or the results of executing the command.

The ASCII to HEX conversion table below is for use with the
command/response tables.
