| CVD2 3D Comb Filter NTSC/PAL/SECAM Video Decoder DVD Digital Camera Driving the Digital Lifestyle Digital TV Imaging IP Cores Product Brief Zoran Corporation 1390 Kifer Road Sunnyvale, CA 94086-5305 Te l 408.523.6500 Fax 408.523.6501 www.zoran.com Benefits Overview 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.
