Zoran's NRED-1 Noise Reduction Processor is a silicon efficient, high
performance Intellectual Property Core for video IC designs requiring
noise reduction. NRED-1 is based on Zoran's extensive experience
delivering high quality, high volume video ICs to major consumer
products manufacturers worldwide. NRED-1 employs impulse, spatial
and temporal noise reduction techniques along with robust motion
detection to achieve the highest quality video possible in the presence
of noise. NRED-1 enables display processors to provide superior
video output and is useful for video compression systems where
reducing noise is essential for eliminating unwanted artifacts.
The NRED-1 Noise Reduction Processor greatly reduces the risk
and time involved when integrating the video noise reduction func-
tion into an IC. Expensive, discrete components can be eliminated
from system designs. When used in conjuntion with Zoran's Frame-
It-1 Deinterlacer, a silicon and memory efficient implementation can
be achieved for systems requiring progressive output.
VIP-II Demonstration System
Zoran offers the VIP-II FPGA demonstration system for evaluation of
the NRED-1 Noise Reduction Processor. The VIP-II allows cus-
tomers to input composite, s-video or component video to test
NRED-1's performance.
