Manual gain control on Video
What can be done ?
Beside the Automatic gain control there is the possibility to manually set the gain of the incoming video signal. When the Automatic
gain control is enabled (ON), the manual setting does not affect the gain, Automatic gain control must therefore be disabled. The
manual gain control must be done on an external pattern with white areas (grey scale bar pattern)

Aspect ratio
Aspect ratios
The standard aspect ratio used in broadcast television is the 4:3 ratio.
However, most of the (non-HDTV) DVD sources nowadays use the wide screen 16:9 or even the Cinemascope
TM
2.35:1 aspect
ratio.
Some DVD sources may even use the anamorphic 16:9 or anamorphic 2.35:1 to take advantage of the higher vertical resolution
offered by the 4:3 ratio. The term “anamorphic” means that the original wide screen image is squeezed in order to
fi
t the 4:3 aspect
ratio.
