Description
AL600 is a highly integration video processor
which supports dual-port input with multiple
graphics/video formats capable and mixing
captured frames output with scaling, overlaying
and alpha blending effects…etc. It can be used
for most video conversion and processing
applications.
AL600 is equipped with a high quality scaling
engine that automatically maintains full screen
output display, regardless of the resolution of the
incoming
signals.
