AL260
1. General Description
AL260 is a highly integration Video Enhancement Processor which supports video input
with multiple video formats then output with De-interlacing and Scaling effects. It can be
used for most video conversion and processing applications.
AL260 is equipped with a high quality scaling engine that automatically maintains full
screen output display, regardless of the resolution of the incoming signals. Applying
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 which’s able to convert and
process the interlaced video to be displayed on progressive panels.
The On Screen Display (OSD) window provides overlay of a control menu, text, or caption
on the output display. It’s built-in OSD generator with 2K Bytes programmable RAM fonts
and also supports optional external OSD.
AL260 is built-in 3-channel DAC for non-interlaced analog output and also supports 24bit
digital output. It’s housed with 208-pin QFP.
