Introduction
The AL260-EVB-A6 is an evaluation board
used to demonstrate the highly integrated
Video Enhancement Processor capabilities
of the AL260 chipset. Its supports video
input with 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 & vertical
directions. It also provides film detection,
advanced de-interlacing, filtering, and
scaling that can be converted and processed
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.
