AL242 Video Decoder from AverLogic

AL242 Video Decoder Description:

The AL242 Video Decoder from AverLogic is silicon efficient, cost effective high quality NTSC/PAL/SECAM video decoder with 2D-Comb filter adapted Y/C separation process. The AL242 decodes NTSC/PAL/SECAM composite video, S-video or component video and converts it into YCbCr 4:2:2, 8-bti/16-bit or YCbCr 4:4:4, 22-bit digital video. Employing adaptive 2D comb filter technology, the AL242 is able to provide the high quality Y/C separation while maintaining excellent frequency response. The result is sharp, high detail video that eliminates unwanted dot crawl and false color effects. Fully programmable video characteristic controls, such as hue, contrast, brightness, saturation, are supported. The AL242 decoder incorporates an advanced vertical blanking interval (VBI) data processor to do data slicing, parsing and decoding teletext, closed caption, and other formats.
