1. Introduction

This quick reference guide provides information related to the greenMachine Testor AV Syne analyzer. The function of an AV Syne Analyzer is to detect the presence of an AV sync test signal and measure/verify the audio/video time delays. It is also used for verifying if the audio channels are swapped.

The AV Sync Analyzer will allow AV sync measurements via GUI as well as in the form of overlays on the output video. The analyzer enables simultaneous timing measurement of up to 4 AV sync input test signals (Testor Quad mode) via greenGUI or via 3* party applications using RemotelF, a LYNX Technik Protocol.

Additionally, in Testor Quad mode one input can be overlayed with the syne measurements
and made available on the OUT 4 electrical port or on optical HDMI ports. In Testor 4K mode, for quad-link 12G signals, the output with overiay will be available on all ports (electrical, optical, HDM). For single link 12G signal, the output will be available on OUT 4 electrical port and Opt Out 2 optical port.

In Testor quad mode, the overlay feature is available on only one processing channel, while the remaining channels can be used as Test Generators. Testor 4K mode consists of only one processing channel and therefore when AV Sync overlays are activated, the test
generator functionality will be disabled

This Quick Reference Guide is designed to help you setup a greenMachine Testor AV Sync
analyzer and provides step-by-step instruction on its operation,

2. Application

The application of A/V Sync Analyzer as below:

Allows measurement of audio and video timing in the broadcast system
It allows an operator to identify AV timing mismatch via GUVoverlay promptly and make adjustments accordingly.
It avoids guesswork and provides a more accurate measurement. It reduces unwanted errors significantly.

3. Setup requirements

Before setting and configuring the Testor AV Sync Analyzer, ensure the following requirement are met:

The greenMachine Titan version used is 868 and above.
The greenGUI version installed must be 2.13 for Windows
The Testor constellation is deployed on the greenMachine.

Note: The Testor AV Syne Analyzer is supported on both Testor 3G Quad and 4K mode.

4. Quick-Setup Guide

4.1. Supported Formats

The greenMachine Testor AV sync analyzer supports the same video format as supported
by the greenMachine Testor constellation.

mode

4.2. Deploying Testor Constellation

Anew greenMachine Testor comes with the pre-deployed Testor constellation. In case the
constellation type needs to be changed. follow the below steps:

zoom

4.3. AV Sync Analyzer

The Testor AV Sync Analyzer allows viewing of timing syne of a AV sync input test signal via, the output overlay of the greenMachine or via greenGUl. The third party application can also use RemotelF for timing measurement information.

Note: The Testor Quad mode consists of four 3G processing channel while Testor 44 mode consists of one 12G single link processing channel. The Testor AV Sync analyzer overlay is supported only on one channel

4.3.1.Viewing AV timing sync on greenGUI
Auser can get the AV timing sync information on the greenGU! by following the below steps:

4.3.1.1. Testor Quad Mode

Step 4: The AV timing gives the following information:
1, Embedded SDI AV timing
2. External Audio AV timing

Step 5: The Embedded SDI tab will provide timing information of the embedded
audio on the AV sync input test signal. The information will be displayed
based on the scenarios discussed below:

Scenario 1: An AV synctest signal connected at the input source:

I the audio channel frequency does not match with the Glits tone
frequency, then the actual audio channel frequency will be displayed as,
shown in the picture below:

An audio channel-swap can be easily identified by checking the sequence
Of the audio group and the left and right channels, as shown below:

In the example above, AES 2 (Group B) is swapped with AES 1 (Group A).
The middle section will represent the audio early or audio delay graphically

The “Syne” column will provide the audio delay measurement in ms.
Delayed audio will have a measurement in +ms and early audio will have @
measurement in -ms.

Note: When an existing AV sync test signal is disconnected from the greenMachine, the values displayed in the A/V timing will a man and will not reset to 0. This may also happen to the audio channels that are not present on the SDI. This is @ known Ksue and will be resolve Subsequent releases.

4.3.1.2 Testor 4K Mode

4.3.2.Viewing AV timing sync via overlays

A. user can get the AV tiring syne information via overlays by following the below steps:

Step 1: On the Control > Main > Video page, zoom into the AV Syne block inside the Global container as shown below:

source

Step 5:

Connect output port for monitoring
Testor Quad Mode:

In Testor Quad mode, the electrical output for the AV Sync Analyzer overlay is
fixed to OUT 4, Atemativey, fie HOM! and optical ports can also be routed via
output video crossbar to receive AV Sync measurement overlay, Electrical
Cuput 1 t0’8 are fied forthe Test generator purpose,

Testor 4K Mode:

In Testor 4K Mode, for signals up to 3G, the selected overlay will be displayed
signal the output ports including electrical, HOM and optical pots, For 126,
SD! single lnk, the video signal with the selected overlay will be available on
OUT 4 electrical port, Optical OUT 2and HDMI out

Step 6: Connect Out 4 port for monitoring and viewing the AV Syne information overlay as shown below:
