CONFIGURATION EXAMPLES
Figs 4 to 7 show examples on how to configure the fader
between the input ports and the outputs, separated into
the composite (and S-video) encoder and the RGB
encoder.
7.1.1.1
Conguration 1
Input MPA can be faded into MPB. The resulting output of
the fader is then encoded simultaneously to composite
(and S-video) and RGB output (RGBIN = ENCIN = 1).
In this example, either MPA or MPB could be an overlay
(menu) signal to be faded smoothly in and out.
7.1.1.2
Conguration 2
Input MPA can be faded into MPB. The resulting output of
the fader is then encoded to RGB output, while the signal
coming from MPB is fed directly to composite (and S-video)
output (RGBIN = 1, ENCIN = 0). Also in this example,
either MPA or MPB could be an overlay (menu) signal to be
faded smoothly in and out, whereas the overlay appears
only in the RGB output connected to the TV set.
7.1.1.3
Conguration 3
Input MPB is passed directly to the RGB output, assuming
e.g. it contains video including overlay. MPA is equivalently
passed through the inactive fader to the composite (and
S-video) output, assuming e.g. it contains video excluding
overlay (RGBIN = 0, ENCIN = 1).
7.1.1.4
Conguration 4
Only MPB input is in use; its signal appears both composite
(and S-video) and RGB encoded (RGBIN = ENCIN = 0).
