AL250 General Description
The AL250/251 Video Scan Doubler (De-Interlacer) is a video conversion chip for consumer video and multimedia applications. It converts interlaced NTSC or PAL, ITU-RBT 601 (CCIR 601) or square pixel, YUV422 or RGB565 digital signals into computer monitor RGB signals for direct connection to a computer monitor or progressive scan TV.
By using I2C interface control, the AL250/251 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 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) provides programmable bitmap RAM for custom design icons and on-screen control panels.
Overlay function is supported to create titling or on-screen-display menus for video adjustment.
The AL251 provides all the features of the AL250. Additionally, it has digital output in YUV422 or RGB565 format, and can convert NTSC video for VGA LCD panels.
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.
