DVI & RGB Input Block Explanation

)

Main Picture (Input 5 or 6 DVI 480P)

From the selector IC inside the DVI module the user selects input 5 or 6 and that
DVI-RGB signal and sync is sent to IC3901 to be converted to Y/CB/CR and
separate H and V sync. The outputs of IC3901 go directly to IC2803 but only pass
through this IC as they are already component signals and the sync has been
separated. From IC2803 the signals are sent to the progressive unit for size and sync
processing and onto IC4608 for final picture, color correction and sync processing.

Sub Picture (Input 5 or 6 DVI 480P)

Only one DVI input can be used to produce a sub picture (split screen effect) along
with one of the other inputs. If the user selects input 5 or 6, the selector IC inside the
DVI module sends that output to IC3906 for RGB to Y/CB/CR converting along
with sync separating of the H and V sync signals. At this point all signals pass
through IC2806 and onto the progressive unit for twin picture and sync processing.

Main Picture (1080I 33k and 480P 31K Full-Mode)

IC3901 (the main picture DVI output selector) selects input 5 or 6 and converts the
RGB signals into Y/CB/CR signals in 1080I or 480P full-mode format and sends the
signals to IC4305 (the full component switch). From IC4305 the signal directly
enters IC4606 for picture, color and RGB processing. The separated 31k or 33K
sync signals from IC3901 also go directly to IC4606 after passing through switch
IC4610 for sync processing. 480P full-mode requires no size conversion from the I/P
converter inside the progressive unit.

Main Picture (DVI Pure Digital Mode 1080I)

If the user selects Pure Digital mode than the path for input 5 or 6 will go through
IC3907 (DVI/RGB selector IC) and switch IC4601 to IC4606 and enter the RGB
matrix area for final processing before being sent onto the CRT drives. The sync
signal is separated by IC3901 and passes through switch IC4610 and finally
processed by IC4606.

Main Picture RGB 1080I (DSUB Connector 3)

The signal path for the (DSUB) RGB input 3 connector is exactly the same as DVI
Pure Digital Mode. As you can see in the block diagram RGB cannot be used as a
sub picture or in any other scan or screen mode other than 1080I full.
