Gennum Showcases HDTV 10-Bit Image Processing Solutions At CEDIA EXPO 2002

Gennum Corporation demonstrated their recent additions to their Visual Excellenceô image processing product family at CEDIA EXPO 2002.The chipset demonstrated offers 10-bit broadcast-quality deinterlacing and scaling. The GF9330/GF9331/GF9320 devices work in a variety of configurations to deinterlace and scale HDTV/SDTV video for home theatre projection systems and large flat-panel displays.The GF9331 Motion Coprocessor and the GF9330 High Performance Deinterlacer address the need for higher image quality in progressive scan displays by implementing motion-adaptive deinterlacing algorithms with multi-directional edge detection techniques. These solutions perform pixel-by-pixel motion-adaptive processing with automatic 3:2 detection and compensation on HDTV/SDTV video signals up to 1080p/60 frames per second.The GF9320 Scaling Processor allows the user to scale any 10-bit input video format to the desired output format, using a 24-tap poly-phase filter. It is ideal for aspect ratio conversion as well as dynamic pan, scan, and zoom effects. A built-in color space converter allows for a variety of output modes such as HDTV, WXGA, and user-defined arbitrary modes.For cost-sensitive applications, product designers can use the built-in spatial deinterlacing capabilities of the GF9320. Higher quality, motion-adaptive deinterlacing can be achieved with the addition of the GF9330 and the GF9331 through a seamless interface. All three devices employ 10-bit broadcast-quality algorithms. For more information, visit www.gennum.com.
