Functional Description 

he AL251 Video Scan Doubler (De-interlacer) is a video conversion chip for consumer video and multimedia applications. It converts interlaced NTSC or PAL, ITU-R BT 601 (CCIR 601) or square pixel, YUV 422 or RGB 565 digital signals into computer monitor RGB signals for direct connection to a computer monitor or progressive scan TV. 

By using I2C interface control, the AL251 can also be programmed to co-ordinate with various input resolutions, adjust screen positioning and crop video noise from around the original input video boundary. 

The internal RGB video lookup tables (LUT), which are controlled via the I2C interface, can provide gamma correction for calibrating the color accuracy of different types of CRT's and improving the contrast level to display more vivid pictures. 

A built-in on-screen-display (OSD) with programmable bitmap RAM allows custom design icons and on-screen control panels. Overlay function is supported to create titling or on-screen-display menus for video adjustment. 

The AverLogic proprietary digital signal processing technology creates a highly stable video image without tearing effects or jagged edges. The output picture is smoother and has less flicker than the original input signal/picture. This technology also keeps the gate count of the AL250 scan doubler low while outputting high quality video compared to competitors products. This will help expand the market for video applications, especially the cost sensitive ones.
