Introduction
This
evaluation board demonstrates the capabilities
of the AL260 IC, which is a highly integrated
Video Enhancement Processor. It
supports video input in multiple video
formats which is then output with De-interlacing
and Scaling effects .It can be used for
most video conversion and processing applications.
The AL260 is equipped with a high quality
scaling engine that automatically
maintains full screen output display,
regardless of resolution of the incoming
signals.
Employing Averlogic’s proprietary
scaling algorithm, the primary input video
can be scaled up and scaled down independently
in horizontal and vertical directions.
It also provides film detection, advanced
de-interlacing, filtering and scaling
which allows it to convert and process
the interlaced video to be displayed on
progressive panels.
The AL260 has a built-in 3-channel DAC
for non-interlaced analog output and also
24-bit digital output.
