7.1.1
Figures 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
Input MP
the fader is then encoded simultaneously to composite
(and S-video) and RGB output (RGBIN = ENCIN = 1).
In this example, either MP
(menu) signal to be faded smoothly in and out.
7.1.1.2
Input MP
the fader is then encoded to RGB output, while the signal
coming from MP
output (RGBIN = 1, ENCIN = 0). Also in this example,
either MP
faded smoothly in and out, whereas the overlay appears
only in the RGB output connected to the TV set.
