CVD2-PB-1.0

Zoran’s CVD2 Video Decoder is a silicon efficient, cost effective,

high video quality Intellectual Property Core for IC designs requiring

video input. The CVD2 decodes NTSC/PAL/SECAM composite

video or S-video and converts it into YUV 4:2:2, 16-bit digital video.

Employing adaptive 3D comb filter technology, the CVD2 is able to

provide the highest quality Y/C separation while maintaining

excellent frequency response. Color transient enhancement

provides for fast transitions on color boundaries. The result is sharp,

high detail video that eliminates unwanted dot crawl and false color

effects. A fully digital design, the CVD2 requires the addition of only

an A/D (two for S-Video support), a DC restore circuit and frame

buffers for implementation.

CVD2 is based on Zoran’s extensive experience delivering high

quality, high volume video ICs to major OEMs worldwide. Proven in

silicon, the CVD2 Video Decoder greatly reduces the risk and time

involved when integrating the video decoding function into an IC.
