Product Brief
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.
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.
Deliverables
• RTL (Verilog) source code
• Bit accurate C++ model
• Synopsis synthesis scripts
• Test input files
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.
• Documentation
• FPGA evaluation board available
Features
• Decodes NTSC, PAL or SECAM composite video or S-Video into
the YUV 4:2:2 format
• Adaptive 2D Comb Filter provides high quality video:
– 3-line 2D Comb Filter for NTSC & PAL
• Component video inputs supported
– 5-line 2D Comb Filter for PAL (optional)
• Decodes all variations of the NTSC standard
• Decodes all variations of PAL standard
– (I, B, G, H, D, N, M, combination N)
• Auto-detects video standard (NTSC, PAL or SECAM)
• Auto-detects and locks to VCR trick modes
• Decodes weak and noisy off-air signals
• Excellent quality Y/C separation
• Auto-detects and decodes Macrovision copy protection
• VBI decoding supported
– minimizes cross luma and cross color effects
• Superior frequency response preserves fine detail
• Accepts up to 11-bit inputs from A/D converter
• Digital automatic gain control (AGC) supported
• Silicon efficient design of approximately 130k gates
• Requires only a single clock input ranging from 20 to 30 MHz
• Process technology independent, fully synchronous design
