5.3.4 SDI Pattern Generation
When the SDI format is 12G, the same SDI pattern generation settings apply to all four
outputs.
When the SDI format is not 12G, the SDI pattern generation settings can be set separately
for each output. But the fixed pattern and user pattern cannot be generated simultaneously.
