Mode 12 is used to support dual zone OSD output without disturbing either video stream. Using this mode, two inputs (for example, 480p
from the video TTL input port and 720p from the Serial Video Rx) can be applied to the part, processed and connected to the OSD core.
The OSD can be blended onto one or other of the two video streams and switched between the two video streams without causing any
disturbance to either.
