Description
The AL242 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. |
