The AL260 Video Enhancement Processor is a highly integration Video Enhancement Processor which supports video input with multiple video formats then output with De-interlacing and Scaling effects. The AL260 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 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 mode detection, advanced motion adaptive de-interlacing, filtering, and scaling which's able to convert and process the interlaced video to be displayed on progressive monitor or panel.
