This tells the VLS-2000 what type of video source material is being presented to the
device input. Combined with the Screen setup, the VLS automatically calculates the
best image transformations to perform to get the largest possible image in the correct
aspect ration on the display. Source should be set to either 16:9, 4:3Full, or 4:3LtrBx,
depending on the format of the supplied input. Figure 3-3 shows the 6 possible
combinations of input Source and output Screen, with the image processing that will
be performed.
Some examples of setup combinations are given to show the flexibility provided by the
VLS-2000, when connected to a 4:3 format projector or monitor:
 Showing a cable TV broadcast, set Source to 4:3Full to display the video on
the entire screen.
 Showing an anamorphic DVD movie on a 4:3 monitor, set the DVD output to
16:9 and let the VLS-2000 do the scaling to letterbox format by setting source
to 16:9.
 Showing an anamorphic DVD movie on a 4:3 computer type projector, set the
DVD output to 16:9 and let the VLS-2000 do the scaling to letterbox format by
