12.2.3 Protocol Table: Mimicking OSD
You can associate a function number to its description and valid parameters
intuitively by navigating the OSD menu according to the following logic:
A function number is directly related to its location in the OSD menu.
For example, the third menu on the OSD is Process (3 in the hundreds). The

the Process submenu (see also Section 6.1 ). When navigating in the OSD MENU
you will be able to see the Film Mode valid parameters.
Note that SDI is not applicable to the VP-770 and appears transparent
in the OSD. The commands related to SDI in the protocol commands
