Averlogic's AL600 DTV Controller Chip is a highly integrated video processor which supports dual-port input with multiple graphics/video formats capable and mixing captured frames output with scaling, overlaying and alpha blending effects…etc. The AL600 can be used for most video conversion and processing applications.
The AL600 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. The AL600 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 outputs.
