| NRED-1 Noise Reduction Processor DVD Digital Camera Driving the Digital Lifestyle Digital TV Imaging IP Cores Product Brief Description Zoran Corporation 1390 Kifer Road Sunnyvale, CA 94086-5305 Te l 408.523.6500 Fax 408.523.6501 www.zoran.com 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 function into an IC. Expensive, discrete components can be eliminated from system designs. When used in conjuntion with Zoran's FrameIt-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 customers to input composite, s-video or component video to test NRED-1's performance.
