6. Random Access Adjustment Mode
Direct
This sync processing has the disadvantage that glitches and other disturbances in the video signal
sometimes get passed and hence may cause problems in the image.
Indirect
This sync processing throws away any disturbances that are not really sync signals. By source switching a
rolling effect on the image can occur. This sync processing is preferred especially with low quality material.
