Introduction
The AL260-EVB-A8 is an evaluation board
used to demonstrate the highly integrated
Video Enhancement capabilities of the
AL260 IC. It
supports video input with multiple video
formats and can 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 & vertical
directions. It also provides film detection,
advanced de-interlacing, filtering, and
scaling that can convert and process into
interlaced video to be
displayed on progressive panels.
AL260 has a built-in 3-channel DAC for
non-interlaced analog output and also
24-bit digital output.
