Description
Zoran’s CVD1 Video Decoder is a silicon efficient, cost effective,
high video quality Intellectual Property Core for IC designs requiring
video input. The CVD1 decodes NTSC/PAL/SECAM composite
video or S-video and converts it into YUV 4:2:2, 16-bit digital video.
Employing adaptive 2D comb filter technology, the CVD1 is able
to provide 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. A fully digital design, the CVD1
requires the addition of only an A/D (two for S-Video support),
a DC restore circuit and line buffers for implementation.
CVD1 is based on Zoran’s extensive experience delivering high
quality, high volume video ICs to major OEMs worldwide.
Proven in silicon, the CVD1 Video Decoder greatly reduces the
risk and time involved when integrating the video decoding
function into an IC.
