Benefits Overview
Zoran’s CVD1 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 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.
Deliverables
• RTL (Verilog) source code
• Bit accurate C++ model
• Synopsis synthesis scripts
• Test input files
• Documentation
• FPGA evaluation board available
CVD1 is based on Zoran’s extensive experience delivering high qual-
ity, high volume video ICs to major OEMs worldwide. Proven in sili-
con, the CVD1 Video Decoder greatly reduces the risk and time
involved when integrating the video decoding function into an IC.
