Figure 8-2. X75OPT-V2A Video/Audio Timing Feature
Transmitter
Firmware versions 1.7 or later are capable of transmitting a special V2A
video/audio test pattern. This pattern may be used directly to measure a
system's relative video/audio timing delays, or recorded for later use. To
manually configure an X75HD/X75SD unit to output this test pattern,
follow these steps:
1. If an X75HD sub-module is present, perform the following steps to
enable the HD TSG:
i. Navigate to the Video Setup>Processing>HD TSG &
Slide menu.
ii. Set the HD-TSG Select parameter to Color Bars 100%.
iii. Set the HD-TSG Enable parameter to On.
2. Enable the SD TSG by performing the following steps:
i. Navigate to the Video Setup>Processing>SD TSG &
Slide menu.
ii. Ensure that the Keyer/TSG Insert parameter is configured
to the correct video path.
iii. Set the SD-TSG Select parameter to Bars 100%.
iv. Set the SD-TSG Enable parameter to On.
3. Set all audio left-channel outputs to Tone 3 and all audio
right-channel outputs to Tone 4.
4. Navigate to the Video/Audio Timing menu and set the V2A Tx
Enable parameter to Enable.
To disable the V2A blank insertion, set the V2A Tx Enable parameter
to Disable.
