HD AV Sync
Sometimes Digital TV encounters a delay between
picture and sound. If this happens you can
compensate by setting a delay on the sound so
that it effectively ‘waits’ for the picture to arrive:
this is called HD AV Sync. Use AD to scroll up and
down through the delay amount, which you can
set at anything between 0 and 300 ms.
